This week we are featuring a puzzle with quite the reputation , The Devil's Chessboard, which won the prestigious Himiki Puzzle competition in Japan in 1990. When I use to travel and set up a booth at various craft shows around Florida this was always one of the most popular. The brain teaser consist of 16 pieces. Each wood piece consist of one dark and one light colored block. What makes the brainteaser so interesting is the angles of which each block is cut. The odd angles create a multitude of assembly options which add a layer of depth and logic when working toward the solution. The image below provides an illustration of what I mean regarding the angluar cuts of the puzzle pieces.
