The Devils Chessboard was created by famous puzzle designer Will Stijbos and it won the prestigious Himiki Puzzle competition in Japan in 1990.
Made up of 16 pieces that all have a white and dark block and are cut at different angles. The aim is to fit all the pieces into the box to create a two layered 5 x 5 checkerboard pattern with colours matching on both layers and that is flush on the surface.
A very challenging puzzle that is likely to leave most stumped.
This measures 120 x 120 x 38mm.
The solution is included.
