The Bernoulli Chest # 1

$

One of my puzzling mates recently commissioned a rather special puzzle chest - the pictures he sent me looked spectacular, so when he offered to write up a guest blog post on it I dodn't take long to mull it over. Here it is - over to Matt:

A very special thanks to Allard for letting me ramble on in his place in the interwebs.

I’ve been seeking an everyday functional trick chest that has a few drawers that open rather simply and a few more drawers that have a vastly more complex opening sequence.

As I was pondering what type of wood I wanted the chest to made out of and look like I was reminded of the very complex and beautiful yosegi (bits of different wood formed in such a way to make geometric patterns) made by Mr. Yoshiyuki Ninomiya of the Karakuri Group. 


After searching the internet for yosegi for a while I happened across a beautiful wood jewelry chest with a strip of yosegi going around its front edge. This beautiful jewelry chest was made by Mr. Nicholas Phillips of Affine Creations and is currently the cover photo of Affine Creations Facebook account


I contacted Nicholas to see if he could make me a special trick chest with different yosegi on the drawer fronts. He was very enthusiastic about the potential project and mentioned he is fond of making Japanese style puzzle boxes and the challenge of making tricks for the chest is something he would love to take on. Based on his past work and enthusiasm I decided to take a chance and commission him to make me a trick chest.

After a few back and forths with Nicholas on drawer layout we decided on a 14 drawer layout that would bring the chest to a size of 17-1/2" tall x 14-1/4" wide and 11" deep.


Next we discussed that I would like multiple differing yosegi patterns covering the front of the drawers on the trick chest so when the chest is not being played with it will look beautiful and mesmerizing. Nicholas quickly began sketching out yosegi patterns and started building. The woods chosen for the chest were figured cherry, kiaat, and Caribbean Rosewood.


The tricks to The Bernoulli Chest # 1 vary from somewhat simple for easy access to a drawer when I’m half awake in the morning to vastly more complex for puzzling. For example, the second row has four drawers that work together in a sequential discovery puzzle in order to unlock the drawer, but to get to the key item in the first drawer that will help one open another drawer in that row one must learn how the drawer opens by itself. 

One drawer is a separate entity unto itself inasmuch as it's a self-contained Japanese-style puzzle box with sliding keys and panels. 

The last 2 rows contain a total of six drawers that work together in a kind of binary logic puzzle that releases one drawer when its corresponding drawer(s) is closed or open. 
 
One of the cool pictures of Nicholas building the chest on his tumblr shows how the aforementioned binary logic mechanism works, but even with a picture of the “mechanical computer” it's still quite puzzling to figure out its operation.

I’m very excited to have this trick chest in my collection and use everyday as a functional piece of art. I hope Nicholas Phillips of Affine Creations continues to make trick chests and puzzles into the future.

SMS Box

I should warn you before we start, this blog post is going to be a little different! 

Trust me, there are no spoilers in here - I know that some people will still be thinking about buying one, and MANY will still be playing with this puzzle...


I spent months on this box (on and off, as you do) and I failed to solve it… I needed help… TWICE! It is a BEAST of a puzzle … and I’m a big fan!


The SMS Box, or to give it its full pedigree name: SMS Box sequential discovery Limited Edition puzzle is Brian Young’s latest special project. While the design is credited to Brian, he makes no bones about the fact that its very existence owes a lot to Junichi Yananose’s skills at both CAD-ing and crafting. 

Getting the design properly ironed out and making 130(!) of these beauties has taken up a lot of their time over the past year… 

I resolved some time ago that I wouldn’t ever miss out on any of Brian’s limited editions again – since I started collecting puzzles more or less seriously, I have passed on one round of them and immediately regretted it, and I’ve been trying to pick up copies of those puzzles in auctions ever since – no luck yet! When Brian first offered the SMS Box, I piled in and ordered one, along with a couple of other goodies that I’d been meaning to get from him for a while, you know, to make the postage from down under worthwhile?


That package duly arrived in early July and the SMS Box really is a statement piece – it looks brilliant! Brian has literally crafted an old-fashioned telephone out of wood and hidden some puzzly-bits in the gubbins. The goal of the puzzle is to use the phone to receive an SMS… which sounds quite hi-tech for a wooden phone, but hey, I reckon Brian can do just about anything with wood… 


There’s obviously a handset on the top – which when lifted shows a couple of sprung buttons – one of which appears temporarily disabled – hopefully that wasn’t shipping damage! The cord attached to the handset tugs out of its hole in the side of the phone without showing much interesting… and there’s a huge dial on the front – beautifully made, looking rather realistic (albeit wooden!) and it turns quite freely, with the occasional interesting sounding noise…


You’ll find all of that in the first 15 seconds of playing with one of them, and that’s about as much as I progressed for several days! 


I couldn’t find anything interesting on the handset and for all I knew, the dial was purely decorative and I’d bought a solid block of wood with some strange noise-makers inside it… surely Brian wouldn’t be THAT evil, would he?


After a chat with a mate, and a little more inspiration I managed to get the dial to play a different tune, and then actually managed to make something interesting happen… PROGRESS! I had finally managed to get something to actually happen, and not only that, I could undo and re-do it at will… 

That tiny little step (a positive step, but as I now know, an infinitesimally small part of the total solution) was all I managed in my first month with this puzzle…


At about this stage I found myself in Japan where I bumped into Brian and Sue in the back streets of Japan’s second city… and as you’d expect at some point the conversation turned to the SMS Box – and I admitted to my virtually non-existent progress on said puzzle. Brian was quite sympathetic, and said that not many people had made much more progress, and then the conversation moved onto something else more interesting – probably “I’m hungry. Let’s find some dinner.”


Not much the wiser on my return from Japan, I’d pick it up every now and then and try something different… in fairness I also kept trying the same old things expecting something different to happen (yes I know! I’ve used that quote myself in the past in this very blog!). Once or twice I’d even had some brilliant flashes of inspiration in my sleep and then tried them out in the morning, only to be disappointed, again. 


One or two of my similarly confused mates would send the odd email now and then sharing their tribulations, but none of us was getting anywhere at all…


... and then an angel sent out a partial solution, suitably spoiler-warned with zero chance of anyone unwittingly seeing anything they didn’t want to… but by that time, I wanted to – so I worked my way through the document – pausing at several critical junctures to think to myself “Good grief! I would never try that…” 

Now to put things in perspective, this document talked you through the first main lock – and then stopped – that mechanism alone is thoroughly evil, brutal even… and I feel no shame in not solving it myself… if I hadn’t been given the solution to that bit, I’d probably still be where I was before I toddled off to Japan. 


Solution in hand I walked through opening the first main lock and it’s perfect… now that I understand it I can open it repeatedly – but there is NO WAY IN HECK that I’d have worked that out myself… Respect, Mr Puzzle. Deep. Respect.


From there on I was back on my own again… I had more to play with, I’d even found a use for a rather esoteric tool that I suspect many will have overlooked… found something important and I was pretty sure what needed to happen next – but I couldn’t find the right secret sauce to make it happen… 


Of course one of my mates did and duly sent me a photo proving he’d finished the puzzle – without any spoilers… he taunted me for a little while before giving me a hint – just enough of a hint to allow me to discover all manner of magic myself and experience the final reveal – which is a magical little piece of revelation all on its own – complete with Brian’s great Aussie wit. 

A lovely end to the journey…


So what do I think – of the puzzle where I needed a step-by-step solution for the first part and a hint for the second part? 

It’s terrific! 

Cheap, it ain’t. 

Brutal as a puzzle, it is. 

Buy one, you should. 

Little Kenny & Little Bruce

$

I have a new go-to puzzle to give to unsuspecting puzzlers when I’m around and they don’t seem to already be working on something else: Little Bruce. 

Little Bruce joins Little Kenny in that category of puzzles that I know I can give to virtually any puzzler and they’ll enjoy solving it. Both have been designed and made by Ken Irvine. They both consist of just four pieces, they share a common size and shape (4*4*3) and even share an unusual little half-block somewhere that really confuses things. And they’re both named after his grandsons.


Little Kenny was a gift at IPP in Ottawa and Little Bruce was thrust into my puzzling paws in Kyoto earlier this year. Now I know that I’ve written a little about them in my various IPP blog posts, but I’ve been feeling for a while that they really need their own blog posts to give them their rightful place… so here goes!

Now, the first thing you need to know about these is that Ken is a big fan of using rotations in his puzzles – I’ve written about a couple of his designs in the past and the one thing they share, is a rotation somewhere along the way… now ordinarily, that might seem like a bit of a spoiler… trust me, it isn’t!


With both of these puzzles, the eventual shape is pretty clear from the start… as is the positioning of the various pieces – your only challenge is to work out how to get there from having a pile of pieces in your hands. 

Now when I first got my hands on Little Kenny back in Ottawa last year it took a couple of days of fiddling on and off before I finally managed to assemble it for the first time… I went through my usual stages of solving puzzles:
1.    Thinking “this should be easy”
2.    “I must be missing something obvious”
3.    Thorough bafflement
4.    Believing it isn’t possible, until finally
5.    Solving it!  


I spent quite a while on steps 3 & 4, at one time wondering if Ken was having me on and was substituting an assembled copy just to convince me that 4 incompatible pieces would actually go together… 


The final “A-Ha!” moment was worth it though!


… and a year later I was delighted to see that he’d entered it in this year’s design competition – exposing it to a whole new audience and hopefully getting a few new fans in the process!

While they were all playing with Little Kenny, Ken had given me a copy of Little Bruce which had me confuzzled all over again. 


Four pieces, a couple of spare voxels inside somewhere – lots of ways to assemble some of the pieces – and no way in heck of getting the final piece into the right place… it definitely requires some Think©ing and it rewards experimentation and rigour… and everyone I’ve given it to so far has not only solved it, but enjoyed solving it… you can’t really ask for more than that! 

[…before you ask, my copies were made by Ken and I don’t think he makes puzzles for sale… the copy of Little Kenny in the Design Competition was made by Tom (who does, and might be open to a polite request or two)… that's Tom's version on the left in Lacewood... and recently a chap called Eric has posted a picture of a Little Bruce prototype... so watch that space. You're welcome.]

Celebration of Mind 2016

Just over a week ago I had a message from Simon Bexfield to check that I’d received an invitation to his Celebration of Mind in Letchworth last Saturday. It turned out I hadn’t and I’d thought it was the following weekend (when I’d been planning to be in The Hague for DCD), so after I’d checked with management if there was anything important happening that weekend, I told him I’d be delighted to join the gathering…

…and so I found myself tooling down to Northern London on a Saturday morning – delighting in the relatively light traffic, even if there was a 15 mile section of road works with average speed cameras along the entire length. In Letchworth my sat-nav and I had a little bit of an altercation when it helpfully took me to the wrong end of the road I was trying to find … with an impassable railway bridge between me and where I wanted to be… a few minutes and a short detour later I’d found the school building I was looking for and recognised Simon unpacking as I arrived… nothing like the sight of a familiar face to confirm you’re in the right place after all.
Grabbing my plastic crate of wonders, I joined the queue inside to get a custom-made name badge from the senior junior Bexfield… complete with its own code to be solved during the course of the day…something I failed at totally!

I found an empty table and laid out a pile of Indian trick locks (and one or two recent wooden puzzles for the more hardened puzzlers) in the hopes of attracting one or two new converts to the joys of trying to solve trick locks… before wandering off to catch up with old friends.

Steve was walking around with his half-brick in a bottle – which looks a lot more impressive in real life than on FaceBook, FWIW – pointing out that it was just a half-brick, because a whole brick would obviously be impossible!

Several tables of interesting games (most of which I’d never seen before) had quite a few takers during the course of the day – at one point someone was being taught to play Hive and I should have paid attention and picked up the basics (I’ve been meaning to learn to play for a while!) but I probably got distracted by something shiny somewhere…

Simon had printed off several odd semi-spherical shapes for us to play with… they look pretty odd until you put a light source (like a camera- phone flash)  in the right spot and notice that the shadows unexpectedly cast a regular rectangular lattice…

Louise Mabbs had a wonderful display of mathematical quilting and fabric knots – hands-down the most colourful table!

Most folks got roped into giving a short talk on something vaguely Martin Gardner-related – mine was literally the briefest possible introduction to Indian Trick Locks and an invitation to play with the dozen or so I’d brought along… especially if you haven’t played with them before… and I’m delighted that I had a good few folks settle down for a good spell of puzzling…

The talks ranged from the really simple (mine!) to the wonderfully complex (Alex’s talk on counting partitions of integers had me Googling several things he’d mentioned during the following week and enjoying a little trip down a mathematical memory lane), Louise talking about her quilting designs and Natasha talking about her book on the development of the chess mind, Tim demonstrating his latest toys and Alison telling us just how interesting the number 2016 really is…

Simon set us a lovely statistical challenge: you have a tea caddy with 100 tea bags in it – they’re joined in pairs initially (it must be a North London thing!) – you successively dip in and take out a tea bag… sometimes you’ll get a pair, in which case you separate them and replace one of them in the caddy, using the other… Now clearly your first draw is never going to be a singleton, and the last draw must be a singleton… but what about the chances along the way … and when you get to the end of your supply of tea bags, what was the average probability of drawing out a single tea bag during that process?

(I should admit to feeling very silly when I checked my answer… I had massively overcomplicated things as usual!)

In between all the talks there was a cracking bring-and-share lunch and plenty of coffee to keep us going throughout the day….

Stimulating company (there were some VERY BRIGHT people there!!), toys and games, interesting talks – a damn fine thing to do in memory of the guy who did more to popularise our vices than anyone else. :-)

DCD 2016

What a fantastic weekend!

It started for me with a rather rude alarm waking me at 3:05am on the Saturday morning (I’d given myself 5 minutes extra… it didn’t really make things all right!). Shortly before 5am I was sitting in an airport coffee shop moaning about my fate on social media – I won’t bore you with all of the sympathy I received here (mainly because there was none!) but after a leisurely cup of coffee I was heading cross-country at about 35,000 feet (best achieved in an aircraft, in case you were wondering). It always amuses me in aircraft how people stand up as soon as they can and then have to wait 10 or 20 minutes while airbridges are connected before they can actually go anywhere… and then they amble gently down the concourse like this is the morning stroll they’ve come here for… I digress – this is supposed to be a puzzle blog… sort of…

…as I walked out of baggage reclaim and customs I spotted Louis walking in my general direction, and knowing that the others wouldn’t be arriving from London for at least half an hour, we sat down for a coffee and a general catch up on respective families, work, etc. At the appointed hour we wandered down to the appropriate arrivals exit to wait for the London crowd… who seemed to take quite a while – we knew we were at the right exit because we knew they were arriving at 9:05 from London… and yet After waiting a little longer, we headed back up to the next exit, with a similar lack of results… just after we’d headed back to the “right” exit, my phone rang and it was Ali.  While I’m talking to him trying to work out where he is, I spot wee Steve who recognises us and waves – at which point Ali spots Steve and then the two of us… which confuses me a little because wee Steve was supposed to be travelling with Ali and big Steve… we set that aside for a while and regroup at another coffee shop to kill some time.

While we’re enjoying a calm coffee we establish that the Steves and Ali have indeed all travelled from London, and some of them even travelled on the same plane (they moaned like drains about having to sit next to some big bloke that pretty much pinned them into their seats the entire flight and made it almost impossible to enjoy the complimentary French pastries being served on-board (not all of that last sentence is true… it is left in as an exercise for the interested reader to work out which bits weren’t)). Wee Steve, having been told when the others were flying, booked himself similar arrangements, and indeed, if he hadn’t chosen a different airline and a different airport to leave from, he might have been on the same flight as big Steve and Ali… but what matters in the end is that we found one another and more importantly, I had a good story for my blog...

We spent an hour or two chatting and sipping coffees before heading out to Rijswijk where Rob had offered anyone arriving early some lunch…so we got there very early! So early in fact that we ended up loitering outside the library for a while discussing the architecture, and the local take-away joints.  We are, after all, a rather diverse bunch… once we’d established that Rob was home, we headed up and made ourselves at home… puzzles came out and then got cleared away pretty smartly to make way for lunch – for there was a lot of itLaurie arrived as we were setting it all up and we enjoyed a wonderful spread of all things good for lunch…even better than the previous year’s Subways – which were pretty darn nice!

After the lunch things had been packed away, puzzlers began drifting in and we pretty soon had a rather entanglement of puzzlers, although not that many that we’d creating a packing puzzle of puzzlers.

Big Steve and I found a big box of Altekruse-style pieces on a side table that we felt the need to assemble so we asked Rob what puzzle it was… he was very helpful and told us he’d bought it in pieces and had no idea what it was as he’d never seen it assembled. Steve decided to apply his mathematical mind to the problem and determined that there were 36 pieces in the box, quickly leaping to the conclusion that it was a 36-piece puzzle, possibly an Altekruse. Big Steve knows puzzles! 

For what felt like the next few hours we sat on the floor with a tiny fold up table between us trying to work out how to assemble a large Altekruse… Rob had a similar one which would have been useful, only we couldn’t work out how to get that one apart, so we were pretty much on our own… well, I say we were on our own, but in fact we were surrounded by helpful friends all yelling out really helpful suggestions (NO I WILL NOT TRY SPINNING IT!)

We had several false starts, seemingly making progress only to decide that we’d put something in the wrong way around quite early on in the process and having to dismantle everything. Once we’d got the basic structure going more or less right, we found the handy push-pull feature would work and we’d be able to slide another layer into place… there was however a downside in that the process would dump a layer of pieces out the bottom if you didn’t remember to turn gravity off before performing the slide… so we spent a while adding a layer at the top while a layer fell out of the bottom, with Steve eventually getting quite exasperated and asking me why I was doing that… reducing me to tears of laughter for quite a while as we discussed whether it was my fault for sliding the pieces or his for not turning gravity off… I haven’t laughed that much in ages… the tears were literally rolling… and then a short while later we actually managed to get the last pieces in place and declared victory – took a pic or two and then Rob took it away from us lest we considered reducing it back to a pile of sticks again…

I’m not sure about Steve, but I suspect that I used up all of my puzzle-solving mojo (there wasn’t a lot to start with, mind) on that damn Altekruse because I’m almost certain I didn’t solve anything else that day.

By the time we’d finished that puzzle, Rob’s was looking pretty packed with puzzlers: Taus and Isabel had arrived from Denmark, Frans, Wil & Sveta, Rik, Maarten and Chris had assembled from sundry Dutch cities, Nigel arrived from Spain and Goetz and Hussein arrived from Germany…not bad for a lounge-ful of puzzlers! (And I’ve probably forgotten someone from somewhere even more exotic!) 


Sometime around early evening a bunch of us headed toward the hotel to check in and get some dinner…we assembled in the bar (it’s always the bar, with puzzlers…) and when there were about ten of us we enquired about the possibility of a table for dinner – this apparently scared them a little and they asked us to give them half an hour as they were a little busy. So we did, and we drank and puzzled and generally abused one another (figuratively, damnit!)… we eventually sat down for dinner – which was a rather drawn-out affair where we were worried for a while that they’d forgotten that we still needed to order, then forgotten to bring us our food, and then forgotten to bring some of us our main courses… but in the end the food was great and worth waiting for, and we had plenty of chatter and puzzling and fiddling with various little challenges… before settling up with a wonderful combination of cash and vouchers they’d insisted on giving us when we checked in…turning it into a really reasonable meal (for those of us staying in the hotel – and the Danes who kept telling us how cheap eating out in The Hague really is!).

I crashed at about 10 o’clock (see opening line, and I did not take a nap on Rob’s couch like some cough-wee-Steve-cough– people) , with the rest of them playing away in the bar until at least midnight…

We’d agreed to meet at around 8am for breakfast and Louis and I were fashionably late…so we joined big Steve and Ali for breakfast. Wee Steve was somewhat more than fashionably late – I assumed his wooden watch hadn’t coped well with the combination of the humidity and the change-over to winter time. Or it was his phone that hadn’t coped well with one or both of those…?

By 9am we were all wandering down the familiar road in the crisp, sunny morning air to Sint Maarten’s College for DCD proper. In return for a little cash we're loaned a name tag and given a couple of little souvenirs: a puzzle and a customised set of DCD cube stickers (I’m going to have to buy a cube now, aren’t I?).

We headed straight over to Strijbos corner to dump our stuff and somehow I got sucked into trawling through crates and crates of treasures – I must have spent ages combing through a variety of boxes finding all manner of unexpected treasure and making piles of “definitely”, “hopefully” and “probably not” before pulling out my calculator and shifting some treasures from left to right until I was merely broke and not thoroughly in debt!

Having largely exhausted my spending money for the day, I handed over my cash to Wil and wandered off in search of puzzlers to chat to…

Jack had brought me a little more Power for my Tower and then promptly gave me a beautiful copy of his CFF burr – a burr with the letters C, F and F on the faces designed as an entrant for the CFF 100th issue giveaway. No good deed should go unpunished, so I gave him a copy of my IPP36 exchange, tipping the pieces into his trusting hands as I always do…briefly the shoe was on the other foot and I was able to give him a little challenge to amuse him after all the joy his craftsmanship and designs have given me over the past few years.

Michel tried to flog me an enormous Arjeu copy of the Atom puzzle – a one foot ball-of-shiny-balls [he’d recently found two of them!] when I gave him the puzzle I’d brought over from the UK for him … and a copy of Phive Pack, in bits, of course.

Christoph Lohe had produced laser-cut acrylic versions of seven of his symmetry puzzles so I joined the queue to collect a set of them, knowing that I’m almost certainly never going to solve them – but it’s good to have a few puzzles in the cabinet to humble you… although in my case those ones might be gaining the upper hand among the collection!

Tony Fisher had made the trip across the channel with a few bits of his Guinness World Record twisty cube and they are humbling to see up close…seeing Tony constantly pushing the boat out further and further and doing more and more spectacular things is just brilliant!

Lunch was provided in great quantities as usual and I suspect there were several trays of ham and cheese rolls left over at the end of the day…

After lunch there were three lectures:


  • Derk introduced us to the Dutch mathematical magazine Pythagoras aimed at schoolchildren (perfectly pitched for us puzzlers!) introducing us to a number of their puzzles and on-going themed articles – with plenty of audience interaction;
  • Chris demonstrated an interesting feat with a 4*4 sheet of paper that when folded any which way and cut always produced the same  sum of digits facing upwards before challenging the audience to work out why it worked… cue fantastic discussion about chequer boards and origami cranes; and
  • Rob gave a whistle-stop tour through a number of the IPP36 exchange puzzles, describing several of them accurately!

All the while there was a speed-cubing competition happening in the same hall… with the usual suspects solving twisty puzzles really fast – sometimes without blindfolds on! Some seriously impressive skillz on display!

When things started winding down, there was one last whizz around the sales tables to make sure that we hadn’t missed anything important before heading back to the station for our trains to Schipol, where Ali, the Steves and I managed to meet up on the far side for burgers of various descriptions before flying back to Brum and London (several flavours!)

What a fantastic weekend!



Some co-ordination required…

$

Every now and then Johan Heyns posts an interesting picture or three on FaceBook, something he’s experimenting with, something he’s made for his own collection and sometimes it’s something he’s considering offering for sale…


Sometimes those pictures find their way into the odd email from Johan, with prices attached.


Sometimes I reply to those emails quite quickly and then then send some PayPal in his direction…


Recently that rather rash behaviour resulted in the rapid arrival of a pair of new co-ordinate motion puzzles … wooden sculptures that come apart, really…


First is Tadao Muroi’s Triangle Explosion – assembled it displays as a pair of triangles back to back – disassembled you have three identical spikey pieces that look nothing like the assembled version!


Johan had removed the spikey ends on his improved design and they will probably be a lot more puzzler-friendly and significantly reduce the chances of dinging an end or unwittingly damaging a puzzler – I couldn’t stop myself going for the thoroughly dangerous version!


…and going from disassembled to assembled is a wonderfully tricky process requiring more than a bit of careful alignment. Johan’s bits all line up beautifully and he’s taken the trouble to pin the bits together so that they won’t be tempted to come apart with even the most enthusiastic puzzling.


Johan understands the importance of being able to properly display his creations to really show off their features properly, so as with his 4L Co-Mo DD, he’s included a stand that will allow you to display the Triangle Explosion in mid-explode… where it looks great!


Next up was Johan’s own design for a Nest 4L(ayer) Co-Mo which combines a pair of classic four-layer co-ordinate motion puzzles into a single creation.


Pop the centre out and you have a pair of co-mo’s that slide sweetly open and closed…Johan’s got the tolerances so sweet on these that when you half open them and put them into their stand, they will literally close up under their own weight…


Opening is simply a case of knowing when to do what and they will slide apart beautifully…


Some lovely wooden examples of a classic mechanism – Dankie Oom!

Sandfield’s Unlocked Drawer

Way back in October 2012 I wrote about Robert Sandfield’s Locked Drawer– I really liked it, you may recall. 


What I didn’t mention at the time was that it had a younger brother, also beautifully crafted by Kathleen Malcolmson, called the Unlocked Drawer… it’s taken me a couple of years to find a copy for sale, but earlier this year I was able to find a copy of Robert Sandfield’s IPP27 exchange puzzle, and I feel obliged to yabber about it on here…


Now when I saw it has a younger brother, there is a very clear family resemblance: they share the same external features, but they’re made of different woods. The Unlocked Drawer has a beautiful Lacewood exterior surrounding a rather similar looking drawer to the one in the Locked Drawer… and there’s a similar rattle when you shake it. 


You’re told your goal is to retrieve the Texas Quarter from inside the drawer… 


Unlike it’s younger sibling, however, this drawer doesn’t simply slide open and present the coin, in fact, a fair amount of coaxing and tugging will not encourage it to budge a mere millimetre. 


A very close inspection of the drawer itself doesn’t yield much at all – except that it is VERY firmly locked in place… there is literally no play on the drawer whatsoever.


As you’d expect, when you finally work out how to open this box, there are a pair of beautifully crafted dovetails keeping everything where it should be… did I mention that Kathleen presented a masterclass on dovetails in puzzles at IPP36? :-)

MPPXXIV

MPPXXIV was a little different… Gill had fled to warmer climes and she’d left Ben in charge at home. Louis arrived on his customary flight on the Friday evening and by the time I crashed for the night, we’d nattered and puzzled for quite a while… and the next morning there was a row of solved puzzles on the desk showing what Louis have been up to while I’d been asleep… one of the solved puzzles included Eric’s latest Button Box – now opened with its little diamond prominently displayed… I’d been trying to open it for weeks!

After breakfasting on baked goods, Louis and I headed down to the hall to get everything set up ahead of the gang arriving… we’d pretty much got all the tables set up before the first random puzzler arrived – a Spanish refugee called Nigel! Having had enough of it pi$$ing down sunshine, he’d come back to his puzzling roots for an MPP top-up – and he had some unkind things to say about our English weather (Oh how quickly he’s forgotten!) which – to be fair - was being particularly English that day! Quick greetings in the carpark were followed by purchases of soft drinks and milk and we were all set for the rest of the gang to arrive… and arrive they did.

Caption competition anyone?
Wee Steve brought a Danish refugee called Taus along and Big Steve brought the Michael and Ali. Kevin and Shane rolled in on their own and Tim brought hundreds of antique and vintage puzzles along for sale…

Warm cup of coffee in hand, I set about catching up with folks I hadn’t seen in a while (Hey, it’s been almost a month since I saw most of them at DCD!) – sometimes with a puzzle in hand and sometimes with a biscuit – well, there was after all a handy supply of the best biscuits known to man!

Soon enough we settled into a pattern of puzzling, banter and the occasional warm beverage…

Wee Steve brought along his impossible half-brick-in-bottle and a number of puzzles for sale or swap – including a box-full of Nutty Bolt #2’s. I think he managed to maintain the distinction between those that were there for playing with and those that were there for sale / swap…

Shane had brought along a whole bunch of interesting locks and had a great time taunting several of us into trying our hands at them… one that remained stubbornly locked was a combination lock with the combination written onto the back of it (!) … I found the little gas meter locks fascinating – or more accurately, I found the keys for the little gas meter locks fascinating… :-)

Tim had his usual selection of Timeless Treasures for us to rake through – and we spent a while chatting about a stained glass puzzle window in a nearby church and a bunch of mythology around the Knights Templar and their holy loot – some of it apparently re-buried with some puzzling sign-posting somewhere around the turn of the previous century… I had no idea some of this stuff was literally right on our doorstep!  

I’d taken along a copy of the new Stickman Burl Tile Puzzlebox and I had the pleasure of seeing a few people solve it before me … I’d had it since earlier that week and while I’d made a few helpful discoveries, I hadn’t actually come close to opening it yet. Shane had brought along a copy as well, so several folks got the chance to play with a copy of the latest Stickman beauty…


NOT a spoiler!
At one point several of us were in stitches with Shane challenging Louis to a speed-solving contest on the new Stickman(s) – Shane’s technique (I use the word lightly!) was possibly best described as hubristic disassembly – paying scant attention to where any of the pieces came from until he had opened the secret compartment and had a fistful of pieces in one hand and a large pile of bits on the table in front of him… having said that, (a) I’ve never seen anyone solve a Puzzlebox faster than Louis before, and (b) it was a highly entertaining spectacle! (History does record that Shane’s copy was fully reassembled in the proper configuration shortly afterwards – partly by reference to Louis’ copy which had its bits laid out in a slightly more analytical manner.)

Lunch was the traditional combination of piggy buns and fish suppers (you chose your poison – nobody had both, although someone did manage more than one piggy bun!) washed down with those soft drinks I’d acquired earlier.

The afternoon saw some highly successful puzzling, as several folks successfully disassembled and reassembled the two old Mike Toulouzas creations I’d recently acquired, with everyone being super-complimentary about Mike’s wood crafting skills.


Hmm, not quite!
Chris was uncharacteristically slightly less than successful on Steve’s disassembled hex-sticks and dowels puzzle – he’s generally been bringing one or two along in bits to MPPs for a while now, and to date Chris has managed to defeat every single one of them – much to Steve’s delight as he thought they’d never see their fully assembled states ever again… this time either we didn’t give Chris enough peace and quiet, or it was too hard for him – I’m going to go with the former on the grounds that I may need his puzzle-solving skills again in the future… and he’d printed out a couple of copies of a puzzle especially designed for Gill by Stephan Baumegger.

Kevin had a couple of us thoroughly gob-smacked when Chris decided to get his own back on Steve for a piece of particularly amusing banter by scrambling a rather vicious looking twisty puzzle (Curvy Copter Plus?) he’d brought along… Kevin then calmly set about solving the thing, and talking about how it yielded well to a simple intuitive solving approach – you know: move something from here to there – if that moves something out of the way, then move it out of the way first and then replace it once you've done what you wanted… Yeah right! Steve and Kevin then blew our minds even further by demonstrating why this Plus version was even more horrible than even we’d realised by doing a series of 30 degree twists and shifting shapes something horrid – and then yes, solving it from there too… the boy’s a machine!

Louis had brought along a couple of new locks, including a remake of an earlier design and a new  wooden lock with a vaguely familiar ring to it… (we seriously hope that Dick Hensel will get around to making some of those!). The other one was a re-print of a previous design that we all liked, but now that Shapeways allows a little extra specifying of print orientation, they can be made to brilliant tolerances every time, and not require fettling after printing – they’re that good that it was catching me out the night before and I could actually remember the solution! That wooden one greatly entertained me the night before and several people at MPP had a play with it – with everyone saying good things about it… now if only we could get some manufactured… :-)

Nick’s Triangular Prism amused several people during the course of the day, and everyone had something nice to say about the Dream of Zebra.

Around 6pm we tidied up the hall and I invited anyone who was interested back to mine for a fish supper (quite generous of me, given that Big Steve and Ali ended up paying for it!). Several more hours of puzzling followed, and the next morning it took quite a while to re-solve and replace the puzzles that had been played with… another jolly great day’s puzzling with friends.



Dream of Zebra

As with quite a few lust-worthy puzzles, the first time I got to see and play with a copy of Iwahara’s Dream of Zebra was on a visit to James’ Puzzle Museum. It’s a gorgeous big ball of a puzzle and several of us had a great time playing with it that day…

The next time I ran into one was at my favourite puzzle shop in Hakone, after the crowds had left, when the proprietor emerged form the back room fiddling with a copy… and in answer to my pleading looks,  “Sorry, not for sale!” unfortunately.

Dream of Zebra won an Honourable Mention for Iwahara in the 2001 IPP21 Puzzle Design Competition… it’s been around for a while. Yet, if you look back through the historic records of the puzzles auction sites you’ll only see a few of them changing hands, most seem to have remained in the grateful hands of their current owners… and there’s a good reason for that… so when I was offered one recently, I handed over a small pile of cash, swiftly.

Back at home a couple of days later I finally got to enjoy it properly… it’s not that challenging as a puzzle – there is a fixed set of moves to be made, with no blind alleys or detours along the way… follow the path and the final panel can be removed, revealing the maker’s mark inside (the anglicised “Rockfield” in this case).

It’s a lovely item to play with and the fit and finish is stunning…something which must have provided a significant challenge to the craftsman is the fact that the twelve moving panels have been turned into the shape of a ball… and while I’m no expert on lathe-work, one of my (crazy Australian) mates is… and he’s afraid of the sort of wood-turning that would be required here – because there are gaps in the corners between the pieces that would be just begging to grab hold of a tool and throw it across the room rather violently…

Not just a beautiful object, one that required considerably more skill than usual to create in the first place – respect, Hiroshi Iwahara.

A double-double helping of dovetails

I’ve had a slowly growing pile of dovetail puzzles on my shelf-of-things-to-be-blogged-about for a little while now and the time has come to rectify that! So here you go – a bonus-length blog post featuring 4 fantastic puzzles!

The Sandfield Jointwas, I suspect, the first of the genre – crafted by Perry McDaniel, it was Norman Sandfield’s exchange puzzle at IPP14 in Seattle. It consisted of a pair of wooden blocks (Mahogany and Padauk) apparently joined by a pair of intersecting dovetail joints – the first classic impossible dovetail? 

It’s not a super-tricky puzzle, particularly if you’ve already seen the impossible dovetail idea before, but the locking mechanism might take you a little while to figure out. Probably the simplest and most honest of the various dovetail puzzles out there… another reason why I’m inclined to believe it was the beginning of the genre... a good introduction to the series, one to give you a false sense of accomplishment! 

At the next year’s IPP in Tokyo, Robert Sandfield exchanged his Dovetail and a Half– a triangle where each side of the triangle has a dovetail joint on it… so clearly one half of a dovetail must be missing somewhere, inside? Perry McDaniel was on puzzle-crafting-duty once again and the same woods (Mahogany and Padauk) make up the opposing halves of this puzzle. 



Whereas the Sandfield Joint may be a reasonably straightforward puzzle, Dovetail and a Half is not!


My copy came from a friend and I struggled for quite a while to separate the two halves… failing miserably. When a puzzling mate came around to collect some puzzles, I gave it to him to demonstrate for me quickly, and he failed to open it as well… at the next MPP I gave it to the solver-of-all-puzzles not expecting it to remain locked together for more than a few seconds in his dextrous hands… but it would not yield to him either… had I bought a copy that had somehow become locked up? I began to have some doubts, so I did the only sensible thing and bought a second copy – one that came with a copy of the solution… which was a bit different to what we’d all assumed the solution was – and that extra step or two had totally baffled every single one of us – of course if you do the right thing on my supposedly impossibly-locked-up copy, it opens up perfectly… Perry’s tolerances remain perfect fifteen years on – it’s just the stupid puzzler who thinks he knows what he’s doing that can’t open the thing! 
 

Next up is Sandfield’s Cutaway Dovetail Puzzle– Robert’s 1999 exchange puzzle. From the pictures you should be able to tell that it’s form Perry McDaniel and once again uses the same woods – nice little bit of continuity in there?


At first glance, this one resembles a slightly enlarged Sandfield Joint, except that someone has taken a bandsaw to it and cut out one of the corners – leaving the inside edges significantly rougher than the rest of the puzzle. (Nice touch, that!) 


Interestingly on this puzzle, a casual shake of the puzzle reveals something rattling around inside… treasure perhaps, or just part of the locking mechanism – who knows, eh? ;-) 


The locking mechanism on this one is a wee bit different and hopes to catch the unwary who think they’ve understood the ones that have come before and know where this one’s probably heading… 


Finally in this bunch of dovetails, one that looks totally out of place – Dovetail Cherry Surprise Cake was Norman Sandfield’s IPP23 exchange in Chicago… it doesn’t take much imagination to see Perry McDaniel’s lovely creation as a mouth-watering slice of (wooden) cake. This one really stands out from the others, both in terms of its size and its complexity…


If you look carefully at the sides, you can make out a couple of dovetails which should give you a clue as to how things might come apart, but this chap has a few nasty surprises for puzzlers – there are a few distinct phases to getting into the final secret compartment to discover the hidden cherry surprise (cute touch!) – but not only that, there are some rather unusual discoveries long the way – and there’s definitely a sequential discovery aspect to it all as well… a lot of the old tricks, and some news ones are used in there – it’s not just beautiful, it is a seriously testing puzzle!

Stumbling Blocks

I’m ashamed to say that I didn’t spend much time playing with this puzzle in the Design Competition room at IPP36… there were so many other attractive puzzles and I don’t have the skills of a Pletcher who can literally work through solving every single puzzle in the Design Competition in the time available. 


After IPP, I was aware that Tom Lensch was making a few things available so I signed up for a couple of them in the hope that they’d turn out to be fun puzzles… Stumbling Blocks by Goh Pit Khiam was a wonderfully serendipitous discovery in that regard. (I should mention that it was one of the Top 10 most popular puzzles among the puzzlers at IPP36!]


Consisting of a simple frame with a base on it and four simple pieces, your object is to insert the four little pieces into the frame… of course there are a few protruding tabs on the pieces that get in the way a little and then there’s the little matter of the tiniest little cut off corners on one side of each piece and matching little triangular fillers in the frame… 


When the puzzle first arrived I had a quick bash at slotting the pieces into the frame and quickly found that it’s trivial to put any three pieces into the frame – but getting a fourth in there seems pretty darn impossible…


I idly fiddle around with it whenever I’m at the PC in the study over the next few days, with virtually no progress at all. 


At some point my mind turns to the designer and I try something different, and that seems to be an interesting path to explore a little further… until I find a rather clumsy solution – or it seems clumsy to me… 


A little more perseverance and I figure out a rather elegant solution and it is a pure little piece of delight! And of course, if you step back and Think© about things a little, it’s entirely sensible!

Super little “A-Ha!” moment beautifully executed by Tom… with this puzzle the maker’s art is almost as important as the designer’s! 


Heartily recommended to all puzzlers – find a copy and play with it – you’ll enjoy it!

It wouldn't be Christmas if I didn't mash up some barely recognisable pictures into a big ole mess and challenge you to identify as many as you could... so here you go!

This year I've been deliberately kind in my choice of pictures - I think they are are instantly recognisable andI haven't fiddled with any of their aspect ratios at all... it should be simple! :-)

Usual rules apply: send me an email (don't put your answers in the comments- it pretty much ensures that everyone else has a starter-for-ten!) to my first name dot walker at gmail dot com - and if you can't work out my first name, there's a pretty solid clue in the blog's name! Send me a list of puzzle names and designers (bonus points if you tell me who made the puzzle in question - in case we need a tie-breaker!). 

Entries close at the end of 2016... my time.

The winner is the puzzlist who gets most right and they will receive something puzzling (of my choice) in the post.

...and have a very Merry Christmas and a wonderfully puzzling 2017!

The scores have been counted. The results are in. 

So who featured this year? A big shout-out to Goetz for getting in a mighty speedy reply and being the first entry received... Big Steve followed with the first of his entries... with a follow-up set of additions / corrections a few days later... after he'd managed to con me into telling him part of one of the answers at Peter Hajek's EPP: he pulled me aside during some idle banter and took me into Peter's study, pointed at a puzzle in the corner and said "Please tell me who deigned that puzzle." Of course it was one of the puzzles in my collage and without giving it a second though I told him it was Ronald Kint-Bruynseels. And then I realised what he'd just done to me! Chutzpah! 

We also had a first time entry from Steven Canfield, who amused the judges (me!) with some interesting attempts that sounded (intentionally!) more like album and band names ("I know I've seen this before by Early Dementia") - thanks for playing along Steven! 

Nick Baxter played it cool and submitted his entry five minutes before the deadline, blaming his tardiness and some missing names in his entry on some American football (an odd mixture of chess, rugby and full body armour, I believe) games. [I assume he was watching, not playing.] 

FWIW I gave points for designers and puzzle names and didn't use the makers in the end as there wasn't any need for a tie-breaker... and in the end we have Steven Canfield in third place on 83 points, Nick Baxter in second on 94 and Big Steve Nicholls in first place (again?!) on 100 (out of a possible 102) - having only failed to identify a single puzzle... something in common with the others in the top three, although Goetz managed to identify Yusei by Takeyuki Endo... :-)

...next year's will clearly need to be harder! 

Thanks to all who played along - Steve, I shall be in touch and send you something puzzling... 

Hope your 2017's are all wonderfully puzzling!

[I've had this post teed up ready to go for a while but I wanted to put some space between my write-up and Kevin's - over here... a suitable time has now passed.]

 
A few months’ back Shane was visiting along with a fair bunch of other puzzlers. At one point during the afternoon he pulled me aside and said he wanted to show me something… actually he had a few things to show me, but one of them is the subject of this blog… he had a candidate design for Haleslock 2 and he was looking for thoughts on it… in his usual self-effacing style, he wasn’t sure if it was good enough… so a couple of us played with the prototype and we all told him to stop worrying and make up a large batch of them – it’s a great puzzle!


…a couple of months later I came home to find a padded envelope from a familiar London address. Inside was a preview copy of Haleslock 2 in all its glory, along with a sealed solution sheet. I love coming home to unexpected puzzles!


After dinner, I set about running through the solution and was delighted that (a) I could remember how I’d solved it the first time, and (b) it still puts a smile on my face even though I already know the solution. 


Shane’s taken the prototype and produced a highly professional version here – the doctoring of the lock has been beautifully done and the finishing and attention to detail – right down to the stamped signature and number “2” on the top plate of the lock… it looks the business!


OK – let’s talk about the puzzle a bit then – this is nominally a puzzle blog after all! 


Haleslock 2 started out life as a size 37 Squire Strongholdpadlock– but I suspect there’s only a passing resemblance to that original state now… it comes with a useful length of chain locked to the padlock with the appropriate keys on a ring… although one of those keys doesn’t look very useful in the traditional sense… and as you might expect, trying the keys in the lock has little or no discernible impact! (It wouldn’t be much of a puzzle if it just opened, now would it?) 


Along the course of your solve, you will be allowed to see some of Shane’s rather nice handiwork and might even learn a little bit about padlocks along the way… it’s not extremely complex or complicated, but it will definitely put a smile on your dial…


[As I write this, Shane has sold out of all of his copies of Haleslock 2 … they should be available from the usual fine purveyors of puzzles… ]

Peter Hajek hosts a cracking puzzle party at the end of each year where he invites puzzlers from around the world to submit their best puzzle (-related) finds of the year… those that can attend in person present their choices to the assembled puzzlists and then Peter combines those and his written submissions from around the globe to pull together a fantastic little booklet, which is then available to (only) those who have submitted something. I’ve been lucky enough to go along to a few of these now and they’re a wonderful opportunity to catch up with friends from far and wide (there’s usually a few Netherlanders there!), puzzle a little, see some impressive magic and eat a lot!


This year was no different… a couple of days after Christmas, I headed down to London and enjoyed the wonders of English traffic that added an hour and a half to my journey… good thing I set off a little early! When I arrived (late) I received the usual warm welcome from our host, which was even warmer after I’d pulled out a couple of Gill’s walnut cinnamon swirl cakes (they went down quite well during the course of the afternoon/evening). 


I grabbed a drink and set about wishing everyone a Merry Christmas and catching up with puzzlists I hadn’t seen in a while. Oli, Shane, Big Steve, Wee Steve, Tim, Joop, Wil, Laurie and Ethel, Gerard, Clive, David and Louis had all beaten me there so I had a lot of catching up to do… having dispensed with the greetings, Peter herded us all into his living room for the show and tell session for each of us to present our finds of 2016. 


This year Peter had introduced a possible fourth choice – if none of your three main choices were a commercially available puzzle… which was handy if you were struggling to whittle down your puzzle finds of the year! 
 

My three picks for 2016 (plus a bonus commercially available puzzle) were: 



Another of Jane Kostick’s wooden wonders from me this year: Quintetra is a ball-shaped object made up of 30 identical pieces held together with magnets. Inside is a triacontahedron box made up of six identical panels held together by magnets. Inside that box is a great little packing puzzle consisting of twelve identical, if oddly shaped pieces of wood, and a wooden cube, all of which need to be placed inside the box. Fiendish!


MikeToulouzas’ Fairy’s Door is really special – it is a thoroughly beautiful object and a delightful puzzle that won the Puzzler’s Choice award at IPP34! Broadly speaking, it’s a puzzle box with an exquisitely detailed Fairy’s Door on the front of it. (Stunning details in the distressed panels and wooden hinges.) Finding your way through a series of puzzling locks is a whimsical experience until you’re finally able to open the box and reveal the surprise inside.


From the slightly twisted puzzling mind of Ken Irvine comes Little Bruce – the successor to Little Kenny. Four simple pieces, a couple of spare voxels inside somewhere – lots of ways to assemble some of the pieces – and no way in heck of getting the final piece into the right place… it definitely requires some Think©ing and it rewards experimentation and rigour… and everyone I’ve given it to so far has not only solved it, but enjoyed solving it… you can’t really ask for more than that! 


A thoroughly unconventional hedgehog puzzle from Radek Micopulos– definitely a puzzler’s puzzle that will amuse even the most jaded of puzzlists. Each end of the cage has an embedded (swivelling!) ball bearing race in it… giving it a brilliantly industrial look. The spiked ball is clearly(!) too wide to get between the bars on the cage, and the spikes are too long to permit any sort of passage through or around the bearing races…


Little Bruce appeared a few times, and Shane’s Haleslock 2 appeared several times, as did Radek’s Axis Hedgehog, Kagen’s Lotus Box and our host's How Box.

After the puzzle presentations, we all tucked into Peter and Katja’s wonderful dinner spread (it’s always terrific!). Some of us had several goes at it and it was brilliant… and after supper Clive treated us to a highly entertaining if somewhat self-deprecating magic show – in spite of his own protestations he was both highly entertaining and mildly baffling. (Thanks Clive!)

Post magic there was coffee and (more!) cake (have I mentioned Gill’s delicious walnut and cinnamon swirl cake?) alongside gentle banter and sociable puzzling.

Some highlights that won’t easily be forgotten: I now know exactly where Wally is, the look on Gerard’s face when Louis decided his Goblin’s Door wouldn’t be fully solved until the solid silver coin jigsaw had been scrambled and reassembled, Steve’s spontaneous disassembly of his Parsellus (sp?) puzzle during his presentation and Wil’s presentation taking the Michael out of Clive after they’d both nominated the same wonderful little Karakuri box.

Another superb EPP thanks to Peter and Katja’s excellent host-age.

The drive home was a lot more pleasant than the drive out on two accounts – the traffic was significantly lighter and I had Louis for company as Mieke and the kids had dropped him off outside London en routeto my place where they’d be spending the next few days visiting us…



Sinterklaas 2016

One of the wonderfully unexpected side-effects of having Louis and his family around for a few days after Christmas was Gill and I being showered with gifts from Sinterklaasthat had thoughtfully been left at the Coolen’s in early December. All we had to offer in return was a few days board and lodging and some time with the new puppy – I suspect we’ll be let off!


One of the gifts was a large wooden lock in the style of Richard Hensel… although it had a few strangely familiar features on it. 


Richard sold quite a few of his wooden locks on Puzzle Paradise a while back with the offer of a partial refund if you could solve it within a week – all of the puzzlers I know politely refused the refund offer, but he kept offering it! His original design went through a couple of iterations and it’s pretty much settled down now… and I’ve been meaning to buy a copy for a while now! 


Opening this present from the Coolens made me grateful that I hadn’t yet, and then I realised it wasn’t quite what I thought it was at first glance – there were a few unusual features on this one (that sprung panel on the front, that thing in the slot at the bottom) that seemed familiar – as well they should because I wrote about a lock that Louis had designed a couple of years ago that shares those features – except that one was a small, white 3Dprinted version... designed to take advantage of a number of the inherent qualities of the material it was being printed in – this was made of wood!


Over a cup of coffee Louis then told the story of sending a copy of his lock to Richard and Richard then asking if he could make a copy in wood – uncharacteristically, Louis said “No” and then went on to explain about his use of the material’s inherent qualities – it’s not called white strong and flexible for nothing, after all! Richard persisted and said he had some ideas… and then a while later Richard’s wooden version duly appeared – and there was a certain degree of gob-smackedness! 
 

Louis subsequently asked Richard to run off a copy for me and my Dutch Christmas present appeared… 


Richard has done a great job of maintaining the original solving process and has only had to resort to a non-wooden artefact for one piece … and he’s working on a wooden version of that piece too! 

A treasured addition to the collection – thank Sinterklaas!



Nutty Bolt No.2

Back over here I wrote about Stephen Miller’s Nutty Bolt No.1…


Nutty Bolt No.2 arrived just in time for MPP XXXiii so several folks managed to get their puzzling paws on a copy in Shrewsbury – sadly(!) I was on a boat in the Mediterranean at the time so I had to wait a little while for the Royal Mail to deliver mine after I’d made it back to Brum…


The rather compact, extremely dense package duly arrived and I have to say that Steve’s delivered on his promises - #2 looks pretty darn similar to #1 – same size bolt, same name plate on the bolt head (‘cept this one says #2 instead of #1!) – even the nuts and washers look the same and they're in the same place – the only difference between them is the name plate and the two dimples in the shaft instead of the single dimple on #1… can you see a pattern emerging there?

Puzzle-wise – this one’s totally different to #1 – and it shouldn’t yield to random fiddling at all – there’s enough in there to make sure that you’ll be locking yourself up some of the time if you’re just randomly playing around…


For puzzlers with good memories and some wider experience, you’ll recognise the locking mechanism from a couple of other puzzles, including another bolt from quite a while back…


I like it as a puzzle and think that it’s going to make a great little set of puzzles… glad to have the beginnings of a nice little set of matching bolts courtesy of Pyro Puzzles.


Hales' Viper

One night last week I had a function after work so I ended up getting home quite late... to my surprise, there was a parcel waiting for me from my mate Shane... he'd mentioned that he'd been working on something "interesting" that he thought we'd like when I ran into him at Peter Hajek's EPP, and then followed that up a few weeks later with an offer email inviting us to opt out if we felt we might not be up to the challenge, along with a number of rather odd health warnings for folks with pacemakers and pregnant women - all of which sounded a bit strange, but hey, why not, eh? I'd duly opted in and signed away my life and then this package arrived... 

So I get home late, but he's piqued my interest and it's a new puzzle after all, so I can't resist the urge to open the package... inside is Shane's usual introduction for his Puzzling Agents (just call me 002!) and an interesting looking wooden object: a box with a square cross section and holes at either end, easily big enough to poke your fingers in but rather ominously covered with a brush like curtain that obscures all view of the insides... A signature on the bottom and the ominous Viper moniker on the top... 

I consider putting it aside until I can spend some quality time puzzling, probably the next evening, but my baser instincts take over and soon I'm fiddling around and exploring the outsides ... Nothing
Try and peek inside... Not much use at all... Listen for things moving around inside and yes, indeed, there's something in there that moves around when you tilt the box... Promising! 

Poke a finger inside expecting the worst... Not quite sure what I'm really expecting... Feel something inside moving but can't get it to do anything... 

Try the other hole - feels different and all of a sardine, it nips me! 

Somehow I manage not to fling it across the room by pure reflex and put it safely down on my desk and then calmly send the following email to Shane - it's titled "You bastard!":

....got home from a team dinner to find Viper #2 waiting for me... couldn't resist the urge and it duly bit me!

You bastard! :-)

I've put it aside until I can play with it properly...

I will report back in due course - when I get the new pacemaker fitted...

You bastard!

Thanks (I think...)

allard



...by return I receive a string of "Crying-with-laughter" emojis... It seems that Viper is working as expected and has claimed 002 as its first victim... 

I give up for the night and plot my revenge... 

The next night I'm home at the usual time and after a suitable stint on puppy duty I attack the Viper once again... 

This time, wary of its bite I'm a lot more circumspect - and it helps not a jot, I still get bitten, several times, while I learn about the innards... 

It's a slow and sometimes painful process, but the box eventually opens and yields up its secrets - including a truly thoughtful gift from the maker...  

Once it's open you have to smile at the wonderful elegant simplicity of it all - the locking mechanism is really straight-forward, yet thoroughly beguiling when you're trying to feel your way without incurring the Viper's wrath... 

My second email to Shane has a lot less swearing in it... 

Great fun and well worth the pain! 

Thanks Shane!

…several ways! 

Shane’s been busy again… a while back he mentioned he’d had an idea for a variation onStewart Coffin’s Three Piece Block puzzle– knowing it was Laurie’s favourite puzzle, we’d seen him work his magic on a rather obtuse variant at Peter’s place just after Christmas. He’d then gone on to tell everyone about a variation he’d discoveredamong my collection that he hadn’t seen before – I’d thought it was a bog-standard version only forLaurie to explain that it was subtly different and he wanted to know where I’d got it from… I pointed him at Brian Menold who hadn’t realised that he’d varied it slightly from the original – and Laurie duly commissioned a pair of variants from him… 


Seeing this, Shane decided he wanted to make a version in Laurie’s honour with some traditional Hales’ Secret Sauce, and a week or two later he sent me a pic of a locked up set of Three Piece Block bits and I duly shouted lots of encouragement down the old email tube… a few weeks later he was back on the blower offering me a special patchwork version in honour of something that Gill had organised for Laurie last year… somewhat humbled by the offer, and the thoughtfulness behind it, I was never going to turn it down. 


Last week I received the well-packed box from Hales HQ – a well and truly locked up set of familiar-looking pieces… except there’s a bath chain locking them together with a neat little padlock… and not a key or other suitable tool in sight anywhere… so I did the obvious and took out the packaging and raked through it carefully (nope, hadn’t missed anything!) and then re-read the accompanying Hales-doc (nope, no clues in there either) – so started puzzling… 


…and I duly puzzled for many a night, playing this way and that and not finding any way to unlock the padlock – I’d developed quite a lot of respect for this puzzle when I eventually sent up a flare to Hales HQ to ask if any external tools were required – let me tell you that I deserved every little bit of the slightly derisory reply I received – I needed a telling off… I redoubled my efforts and still got precisely nowhere!


Taking pity on me, Shane sent me a sideways hint and I found the vital step I’d been missing and I was truly humbled by this puzzle in a second way – this time in the proper “You’ve been PWNED by the puzzle” sort of way – Hales had TOTALLY caught me out and he deserves a right proper degree of respect for this one – it is brilliant and I am somewhat ashamed that I didn’t find it on my own… 


Unlocking the pieces leaves you with “just” Coffin’s Three Piece Block puzzle… which on its own is formidable enough for someone like Laurie to proudly list it as his favourite puzzle of all time…


Shane – you totally owned me with that one!


Thank you…

Karakuri Christmas 2016

I joined the Karakuri Club several years ago and I've never been disappointed, and I tend to encourage any other puzzlers I come across to join up. For a fixed sum per craftsman you get a set of wonderful presents just in time for Christmas... You never know what you're going to be getting, but you're pretty much guaranteed good value for money - and along the way you're providing the Karakuri guys with working capital for the year - I think it's a great deal for everyone.

Last year I opted for six out of the eight craftsmen knowing that I would almost certainly like their presents. 

Tatsuo Miyamoto brought us the Clown Fish box - a super colourful decorated box with an obvious break across the lid of the box. Exploring the lid yields some interesting movements and a peek inside at an animated clown fish. Very cute! 

Osama Kasho produced a Pelican this year, although I must admit that I took a while to work out what it was and spent quite a while thinking it was something akin to the rabbiduck ambiguous drawing ... Of course as soon as someone points out that it's a pelican, you can't unsee it... A reasonably simple opening with a huge storage space inside the big bird's bill, as you might expect!
 
Fumio Tsuburai brought us a new variant on the Coin Bank, which if the name is anything to go by is the 16th variant the Karakuri folk have brought us over the years. The mechanism for this reminded me a little of one of the other Coin Banks I have and one or two purists have been known to grumble about the need for an external tool...  

 
Twin 4 is a further development in Hideaki Kawashima's Twin-series. This is a great little puzzle box that uses all sorts of interesting movements and combinations to eventually allow you to find two large recesses... And the wonderful thing is that you still aren't finished at that point. All of the boxes have their maker's mark on them somewhere, usually on the inside... And if you've been paying attention, when you get to find the second recess, you still haven't found Kawashima-san's hanko- so you need to keep going until you find it... Really nice puzzle!

Akio Kamei gave us a String Box variant that looks pretty similar to some the earlier variants, only this one doesn't behave like them at all! In fact I had a lot of trouble with this one and ended up getting Louis to give me several large hints - it is a bit of a sod and requires a fairly deft touch... You should be able to work out what's going on and what you need to do, but it's pretty darn tricky!


The final puzzle in my Christmas haul was Bean Bag Drawer 3 from Hiroshi Iwahara - if Kamei's puzzle was tricky, this one's a beast! The drawer pulls out a bit quite easily, but it's clear that it "should" come out a lot more, and there's a red slider that doesn't seem to do a lot at all - and somehow you need to manipulate "things" in order to fully open the box. 

Like previous year's Bean Bag Drawers, this puzzle has a wonderfully delicate reset feature that I found myself triggering rather often. A careful inspection does yield some helpful clues as to what you're trying to do, but even then, it's rather tricky, quite fiddly, and then there's that darn reset waiting to send you right back to the start again... It took me a long time to open this one for the first time - Christmas was a dim and distant memory when I opened it on my own for the first time...

...as I write this blog I've just signed up for this year's Christmas presents. 

Go on. 

Spoil yourself!
