This is the third part of my series of posts about the puzzles in the 2012 Design Competition that did not win an award. All of the photos are by Nick Baxter from the 2012 Puzzle Design Competition website.
COG-Cubed - Tom Longtin
I tried taking it apart and didn't have much difficulty, the chunky pieces fit very well and slid nicely, which I liked. I kept good track of where each piece came from, so it was pretty easy getting it back together as well. I'd imagine it would be a bit more of a challenge putting it together from scratch, but probably not too bad.
Constrained Cube - Tom van der Zanden
Personally, I have a hard enough time with regular twisty puzzles, much less ones that won't let me make a move that I'd like to do! I tried to simply get one face complete and ended up getting pretty annoyed at the darn thing. I have a standard way of doing it, and it really makes you work around those limitations. I'd imagine it is a decent challenge to solve! Something to keep those twisty puzzlers busy for a little! The solution was pretty amusing/unhelpful: it basically said to solve it like a regular cube, but to come up with new move sequences to get around the limitations. Easier said than done!
Crazy Pentahedron - Bao Daqing
Double Duals - Jane and John Kostick
I assumed the light blocks went with the light sticks, but the magnets repelled, so I guess I was wrong! The shape that goes on the inside is pretty neat, it looks a bit like a jack, while the shape on the outside fills in the gaps nicely.
Double Symmetry - Tom Lee
Unfortunately, I walked by this one when somebody had left it in the solved state, which pretty much spoiled it for me. I'm generally not a big fan of the 'make a symmetrical shape' group of puzzles. Personally, I like having a better idea of what I'm trying to accomplish!
Eyjafjallajökull-Puzzle - Vladimir Krasnoukhov
Fidgety Rabbits - Namick Salakhov
I'm a sucker for gray code puzzles, so I enjoyed this one. Like Chinese Rings (and unlike The Brain) this one has a long dead end to trap the unwary, so watch out! It is constructed from PVC foamboard using some sort of 3D printing process, so it has this squishy feeling to it but is still quite sturdy.
Gear Pyraminx - Timur Evbatyrov
Genie in the Bottle - Erhan Cubukcuoglu
Erhan. The goal is to free the bottle from the stand, and I thought it would just be a matter of getting the ten sliding blocks in the correct position. However, this one ends up being quite a bit more involved! I can't really get into the details, but this one definitely presents a good challenge, which was a nice surprise. Here's a link to Erhan's post about this puzzle.
Guile in the Box - Scott Elliott
That's all for today! Stay tuned for Part 4 tomorrow!
