Thomas Ball is a mechanical puzzle that looks like a little soccer ball. On a Thomas Ball, the hexagonal sections rotate around the pentagonal sections. The goal is to reach the proper alignment of the hexagonal sections. Currently, Thomas Ball comes in 5 levels of difficulty. For Level 1, the hexagons are one of three solid colors. For Level 2, there are three colored rings to complete. For Level 3 there are 4 colored rings. Level 4 has six interconnected circles (and apparently national flags.) Level five has the numbers 1-20 (with one number occupying a pentagon.)
