Girish Sharma entered a couple of puzzles in last year’s Nob Yoshigahara Puzzle Design Competition and was duly awarded an Honourable Mention for one of them – I rather enjoyed playing with that one and promptly modelled it and printed off a copy for myself… and then enticed a couple of others to play with it and they seemed to enjoy it too… so when I spotted another of his designs appearing in a recent Pelikan release, I promptly added it to the basket.

Cerberus is a neat little 4*4*4 (partial) cube that consists of a wenge ring-shaped piece and three interlocking pieces that are well and truly trapped inside that ring. It’s not challenging finding a couple of pieces that will move, but unless you’re really lucky, you’re going to find yourself trapped up against a dead end… once or twice… I wasn’t lucky – many times!

Find your way past said dead ends and you’ll get into a most wonderful dance of those three little trapped pieces – I know we often use that term to describe the relative movements of pieces in puzzles, but this one really is a rather intricate dance with pieces going round and back and forth until at the 25th move, the first piece is released… and even from there things aren’t trivial to release the last two pieces.

I got to watch a few folks fiddling with it at the last MPP and that confirmed that even when you’ve disassembled it, putting it back together is anything but trivial – amusingly most people seemed to struggle with putting the first piece into the frame! (Think about that!)

An excellent design that packs a whole lot of puzzling into an innocent-looking little cube. Definitely worth having a play with this one if you enjoy interlocking cubes!

Window Lock 2

I really enjoyed Dick Hensel’s Window Lock so when I heard Peter talking about a second Window Lock, I pricked up my ears and duly dropped Dick an email asking to be placed in the queue.

A little while back I had the notification that my copy was ready, so PayPal headed one way across the pond while a small package headed the other way.

There’s a really strong family resemblance here – there’s the familiar wooden case and shackle, this time in oak, and the big acrylic window taking up almost the entire front of the puzzle. Everything is on display, right?

A quick wiggle of the shackle shows that it’s firmly held in place on the left by a large ball bearing and several oddly-shaped bits of wood seem to be holding the right hand side in place. There’s a stray brass ball floating around the middle of the lock and a vast number of carefully shaped little wooden obstacles getting in the way of that ball and indeed of one another.

There’s a tool that can be used o manipulated some of the bits and pieces inside, but form the start there’s almost nothing that can actually be done… so the first order of business sis to find out what’s stopping you from doing anything…

A bit of jiggling and prodding and poking and you can start moving things around a little and freeing up some space… only Bill’s carefully designed things so that you’re invariably going to have to double back on yourself a few times when you realise that you really should have done something else right at the beginning.

I ended up thinking I was making stunning progress several times until I got stopped dead in my tracks by something that needed doing, only it couldn’t be done in the current configuration and everything needed rewinding…

Try and think a few steps ahead, but be prepared to be outfoxed by Dick!

I really enjoyed working out how to get everything where it needs to be and then executing it and (finally) seeing the shackle swing open.

Oh, and you might want to plan the reset as well!

Noodling Box

Eric fuller was a giant among men. Not only as a tall, imposing guy, but often as the bloke with the serious mohawk at our annual puzzle parties. Softly-spoken and an absolute gentleman, he had a rapier-sharp sense of humour and puzzle-chops like nobody’s business. He was a great solver of puzzles, but he had an absolute gift for both designing puzzlers’ puzzles and for selecting interesting designs from others… most people will know him best for the amazing craftmanship in the puzzles he’s been making and selling through Cubic Dissections for years.

The puzzling community lost one of the good guys when he passed away last year – I’m going to miss his larger-than-life personality at IPPs, and I know that there will be thousands of folks who have an Eric-shaped hole in their lives now. My heart goes out to his friends and family who must be missing him so much more than me – hugs to you all.


Noodling Box was one of the last projects that Eric worked on – he’d spoken about it now and then and it sounded one of those projects that he’d dip back into every now and then, noodle around a bit, and then work on something else… until he thought it was ready to unleash.

The name, apparently comes from the act of catching catfish with one’s bare hands (not one’s bear hands, that’s another sport entirely!) by enticing them out of their underwater caves and then presumably grabbing them. I’m no expert, but I wonder if there’s potentially a more effective way of doing all that… either way, I’m sure that it’s at least partially relevant to the puzzle – or just another of Eric’s jokes on an unsuspecting puzzler.

My copy has an African Teak case with a Quilted Sycamore drawer – at least I assume it’s a drawer as it wiggles a bit, but resolutely won’t open. There are a few noticeable holes around the sides, some of which seem to have something lurking just below the surface (a catfish, of sorts?). The front of the drawer has a round knob with a little bit of a wiggle to it… but again, nothing that seems useful at all…

I end up spending quite a while making absolutely ZERO progress until I notice something worth exploring. One thing leads to another and I find myself in command of a small, but perfectly formed, tool.

At this stage I’m pretty chuffed and I reckon it’ll probably be plain sailing from here on in having finally cracked my way in… disappointment awaits… and I end up contemplating increasing dangerous things that I could do with my little tool, as I try things in turn, none of which seem to be of any use whatsoever…

There’s an obvious place for me to want to get to at this stage, only my tool won’t allow… I spend several days Think- (c)-ing to almost no avail.

Progress finally comes from trying something I hadn’t thought of yet – which is obvious really, until you think of it… only you don’t, and you won’t, because it’s Eric, and he knows exactly how puzzlers think… and then uses that against you, totally.

From there on I manage a bit more sustained progress and actually get the puzzle to where someone who hasn’t come across Eric yet might consider the puzzle to be solved… only you haven’t seen his hanko and there are some as-yet-unexplained noises going on inside the box, and there’s altogether too much space left…

Onwards, and sometimes upwards, until some further discoveries, including at least one that will literally blow your mind and then you’ll have not only the hanko, but also your prize – totally befitting a Noodling Box.

The puzzling journey is beautifully designed with definite stages of discovery along the way – there were two or three times that my head was blown on aspects of the solution. Everything is that precisely made it’s virtually impossible to guess what’s going to be happening until it actually happens

The gang at Cubic have really done Eric proud on this one – well done folks!

Even Dia-BALL-icer

Since printing out a few sets of George’s Octaballs, I spotted a new design on his Etsy shop for a rather handsome variant – also called Octaball -  so I shopped a little, you know, to justify the postage across the pond and ended up getting a copy of George’s Flippe Ball (I should have got one of those ages ago!), a Frankenstar and a copy of his Maze Pennyhedron Puzzle which I really enjoyed playing with in the Design Competition. 


This Octaball is properly round and has a great Yin-Yang thing going on in the colouring of the pieces. It’s a variation of the basic Octaball 2, with the exterior expanded into a complete sphere. It retains the great little expansion and contraction feature of the original, although the shapes you’re looking for on the outside are a bit different – you can still play with expanding and contracting by pushing on the opposites sides.
Expand it fully and you’ve got the four strange shapes in two pairs to reassemble. This time it’s worth giving a little thought to the colouring so you get the full impact of the Yin-Yang-i-ness going properly.

While the pieces may have a little more material, it’s still a wonderfully slippery sucker to put together – you will be “blessing” George’s "creativity" when you’re struggling with this one too!


While I’m on the topic of balls, George threw in an extra chocolate box to go with the Triple Chocolate Box set I bought from him a while back. He’s been working on the set and found a fourth box shape that’s been christened Hershey.

As with the previous challenges the object is to place all of the conjoined balls inside the box so that the lid shuts (easily!) – I’d really enjoyed playing with the first three – and was particularly impressed that all three appeared to require a different form of packing to get the pieces into the box…

This box doesn’t disappoint! 

I spent a while trying to establish what the likely packing arrangement between the different layers could be and then it took me quite a while to work out where the pieces needed to be to construct those layers…

If you already have George’s Triple Chocolate Box, be warned, there’s another candy bar in town. (Gill and I have volunteered to sample further chocolatey delights in the pursuit of any further boxes that require naming.)
