Half Hour Cube | Stewart Coffin 1975 Wooden 3x3x3 Puzzle




Half Hour Cube is a handcrafted wooden 3x3x3 cube brain teaser designed by Stewart Coffin in 1975. Coffin estimated a half hour as a good solution time. It looks like a Soma Cube, but where Soma has 240 valid solutions, this has only one.
