There is a lot more, including coverage of Hanayama, Rubik’s and variants, a...

Hajime contacted me out of nowhere and asked if I would be interested in crafting a new puzzle he designed. Given his performance at last years IPP Design Competition, it was a pretty easy sell. Pin Block Case is a unique and very interesting packing puzzle.

This was a hit at IPP and will likely sell out quickly.Construction of this puzzle was painstaking, with...
