The Gamescience ZOCCHIHEDRON™ True D100 is a designing triumph so unique, it's patented! (US Pat No. D-305 553). No larger than a ping-pong ball, yet able to roll all numbers from 1 to 100. With 100 identical faces equidistantly spaced on a spherical surface, there is no doubt which number has been rolled. Its digits are boldly printed in large type to make it easer to read - and those digits are inside the die, where they cannot wear off! Ideal for use with ALL role-playing, miniatures and war games - anywhere an unbiased percentile generator is needed.
