“When you think of puzzles by Osanori Yamamoto you instantly think 'rotations'. With Trap R2 you won't be disappointed but this puzzle is very different to any other puzzle I have seen. Initially it looks like a couple of solid boards joined at the corners with a small wide cylinder between them. The cylinder can move about fairly freely with some interesting limitations but that is it. With a little curious fiddling you will find an unexpected move or two which opens up other possibilities. Trying not to give too much away, I have to say that this needs a bit of careful exploration to get a complete mental image of the shapes involved and then proper planning to arrange them so that disassembly is possible. The first part has to be done blind which makes it a fun challenge. Absolutely marvellous puzzle – totally unlike anything I've seen before and a lovely challenge.”
