This is the Zocchihedron Mark II, with black numbers on a reflective silver base.
Invented by Lou Zocchi and first brought to the market in 1985, the Zocchihedron was the first 100-sided die in the world. It took three years to develop and another three years to produce it. This improved MK II edition first debuted in 1994.
Spherical in shape, it includes special weights inside to help it settle on a number when rolled.
Covered by patents D303,553 and 6,926,276.
Why you'll love these dice:
- Instead of having to roll two dice to generate a number between 0-99 and sometimes adding one, you can use one die to roll 1-100.
- It's so reflective, if you look closely you can see me in the reflection as I took these photographs.
Zocchihedron MK II D100
It is hard to use D100 dice due to ambiguity of which face value is really the right one. Why not build a D100 transparent with water inside with a air bubble ? The air bubble will be always on the true top of the dice selecting the value without doubts.
