D120: Clear

The d120 (120-sided die/dice) is the ultimate fair die allowed by mathematics! It’s based on the disdyakis triacontahedron, the polyhedron with the most faces for which east face is indistinguishable from any other face (apart from the numbers, of course!). These dice are perfectly numerically balanced, meaning that opposite faces add to 121, and the sum of every group of ten, six, or four numbers around a point is the same for all groups of the same type.
