My dice-box covers the gamut of variables:

2 = Coin

4 = Tetrahedron

6 = Hexahedron (=’Cube’)

8 = Octahedron

10 = Pentagonal Di-Pyramid (2 kinds)

12 = Pentagonal Dodecahedron

20 = Icosahedron

30 = Rhombic Triacontahedron

…F.Y.I., I refuse to use 100-sided dice. They look like golf-balls, & take FOREVER to come to rest!

Instead, I use a pair of 10-sided dice – one is marked “0-to-9″, & the other is marked “00-to-90″.
