Perhaps the world's oldest puzzle, this mathematical challenge was developed over 2200 years ago by Greek mathematician Archimedes. Our Archimedes Square Stomachion puzzle is 4 inches square (nearly 5 inches square in wood tray) and consists of 14 polygons of varying sizes and shapes, made from brightly colored wood. Much like a traditional Tangram, you can solve the puzzle (thought to have 17,152 solutions) or create your own designs and patterns. In November 2003, Bill Cutler calculated 536 distinct arrangements of the pieces into a square using a computer program to eliminate solutions that are equivalent by rotation and reflection.
