Yanked My Chain - Chain Store

Chain Store by Goh Pit Khiam

Sometimes a puzzle just yanks your chain, which is exactly what happened with Chain Store.

One of the joys of attending the International Puzzle Party is spending time playing with the entries in the Nob Yoshigahara Puzzle Design Competition.  This is a puzzling wonderland full of all sorts of new designs for a wide variety of puzzle types.  There is something for everyone and I try to spend as much time as possible in the design competition room socializing with other puzzlers doing the same.

One entry in the IPP36 Nob Yoshigahara Puzzle Design Competition was Chain store, designed by Goh Pit Khiam.  It was made by master craftsman Tom Lensch and won the Jury Honorable Mention award.

Now I have a question for you.  Would you rather buy a puzzle that you have already solved or that puzzle that you didn’t quit manage to solve?  Personally, I tend to buy puzzles that I haven’t solved.  Once I’ve solve a puzzle, I’ve basically scratched that itch.  Of course, some puzzles are so brilliant you need to acquire a copy even after solving them to occasionally wonder at and show others.  Case in point is Stumbling Blocks also by Goh Pit Khiam, and a top 10 vote getter in the IPP36 design competition.  I solved Stumbling Blocks very quickly but the movement is so spectacular, I needed to acquire a copy.

At some point, the chain was sufficiently yanked to turn the light bulb on and I managed to stuff those stubborn links into that wee little box.  Once I discovered the required orientation for the links, I found that there is an elegant way to crumple up the chain to pack in the box.

I really liked this puzzle and if you are interested in acquiring a copy, Cubicdissection is planning on releasing a run in the near future.
