Zocchihedron

Zocchihedron is the trademark of a 100-sided die invented by Lou Zocchi, which debuted in 1985. Unlike other polyhedral dice, it takes the appearance of a ball with 100 flattened spots. It is sometimes called "Zocchi's Golfball".

Zocchihedra are designed to provide percentage rolls in games, particularly in role-playing games. It is an alternative to the percentile die, which is used in conjunction with the d10 die.
