Girish's Wooden Entanglement Puzzles

Twisted Rabbit by Girsh Sharma made by Brian Menold

Last week I reviewed a fabulous assembly puzzle designed by Girish Sharma (Shiba Inu) from Pelikan (2 still in stock) and marvelled at the amazing way he is able to create burrs as assembly puzzles that are accessible to the average puzzler (although still very difficult) and very interesting in their challenge and design. Shortly before the Pelikan puzzles arrived, I received a lovely little batch of beauties from Brian Menold's Wood Wonders store. When they were announced, I had to force myself to decide on just a few to add to the collection because I can no longer see even a hint of my desk and the piles of puzzles to be solved are starting to get embarrassingly large in several other rooms of the house much to the disgust and anger of "someone else" who lives here. She has just said that I remind her of those hoarders that we see on TV occasionally living in filth. I did have to protest that they are all very clean which earned me a stare and an implied threat.

Not only does Girish design burrs but he also designs Turning Interlocking Cubes (TICs) which have gotten more and more complex over the last few years. Some of them are quite fearsome in their complexity. There were 3 in Brian's recent release and I got them all.

First up was Snake Eyes - I had thought that having only 2 pieces, it might be a nice starter, slightly easier puzzle to begin with having not done any TICs for a while. The copy I received was made from Cerejeira and Movingui which made a beautiful contrast. The international postal service had broken a joint on mine and I was delayed in my play by having to glue it back together again. Interestingly, there is only one way the 2 pieces can be interlocked into each other which is always helpful at first and then I  realised that there were lots of possible rotations that can be done. I started moving them about and getting increasingly worried that I will never get them apart again when I found that I had gone in a full circle and they fell apart on me. That was unexpected! Try again and yet again they rotated around each other in a full circle before finding myself at the beginning. I was obviously missing a move (or 2 or 3 or ...). In fact, this reminded me very much of quite a few of the wire disentanglement puzzles I have played with over the years. Lots of moves that I struggle to remember before ending up at the start. Frustrating but fun. Having done Einstein proud by repeating the same thing over and over again, I finally had enough memory of my moves to be able to recognise my path and also explore ways to get off that path. Several of them ended up nowhere but finally after about 2 days of fiddling, I got my Aha! moment. It is lovely - just 2 pieces and yet so very clever:

Next up was the 3 piece TIC released at the same time (also by Girish) - Snake Eyes

Snake Eyes by Girish and Brian

This version is made using Cerejeira, Wenge and Sipo. I expected this to be a significant step up in challenge and was not disappointed. Brian wrote this:

"Lots of moves and rotations. I think I lost track of the rotations at 9 and the moves at 30! A really fun challenge always has lots of rotations. This puzzle holds up its end in that regard."

3 pieces means that you need to make a choice where to start and I chose wrongly at first because I'm an eejit. I should have picked the 2 pieces that had a restricted way of being introduced. Luckily I realised my error quickly. The two critical pieces can be entangled in 2 ways but just thinking about the end position (of which there are 2 possibilities) narrows it down. Yes, I used thought© not random trial and error to choose my starting positions and then started rotating. Oh boy! There are a LOT of rotations! I lost count well before the 9 that Brian did. Thinking that I might have gone too far, I backtracked to the beginning a few times until, at one point, I found that I couldn't get back to the start. I was fully committed to this puzzle now. It needed another 2 days to find my way through - and that was just those two starting pieces! Yet again, Girish has designed a wooden entanglement puzzle here with more constraints than a wire one has. It is marvellous! Once I had the first two pieces correctly placed, it was obvious where the final one went and only a bit of work to back track to make space and then sequentially lock them all together:

3 pieces make my cube - the Snake eyes are visible

I have some serious concerns about being able to take it apart again. I have absolutely no idea how I did it! Yay! Brilliant fun - always looking for more from this great pairing of craftsman and designer.

Yesterday was the last MPP of the year and for once I wasn't working. I headed down to Birmingham and joined the boys for a day of fun, puzzling and a kebab. I am sure that Allard will be writing a story about it soon. Mrs S immediately commented on my arrival home that I had left with 1 box of puzzles and arrived home with 2! Whack! Ouch!

Here is what I got:

Not a bad puzzle haul - it includes what Ali brought back from IPP for me
The cardboard box is a new one from Kyle Chester Marsden with a Xmas theme (I'm saving it for then)

When I took the photo, I actually missed the extra gift from Stefan - he has perfected Micro 3D printing and made a Soma cube with box that are so small that you need tweezers. The one I got was the big one because age made me fearful of not being able to focus on the even smaller one!

Each Voxel is 1mm!
