Manufactured on Hokkaido, Japan’s northernmost island, the 12 pieces in this solid walnut puzzle cleverly interlock to present a challenge right from the start. Finding a way to remove even the first piece of the Wood Blocks Puzzle Octagon will have most puzzle whizzes stumped. Just when you master deconstruction and feel like celebrating, keep in mind that reassembly is equally demanding. Ideal as a desktop distraction for the busy executive or anyone who goes into deep, thought process mode. When the Puzzle is not in use, the enigmatic design doubles as an Escher-esque desk accessory. Not recommended for impatient types.
