## What dice has the most sides?

All dice are polyhedra (Greek for many-sided), but the D120 is a special variety called disdyakis triacontahedron. It features 120 scalene triangular faces and 62 vertices.

## What is a nine sided shape called?

(The top and bottom points have 5 faces meeting; the other corners have 3 faces meeting.)

## Why does the d10 have a 0?

The one with two digits is just telling you the tens digit, and the one with one digit is the ones digit. If you’re rolling only that die with 0, 10, 20, etc., then a 10 = a 1 and the 00 = a 10. 0 or 00 on a d10 just means the highest number.
