How many dots are there on dice?

Answer 1

This depends on what sort of die -- the singular for dice -- you are using. There are many types, from d4 which has 4 sides, to d100 which has 100 sides.

The most typical die is a d6 or 6-sided die: it has a 1, 2, 3, 4, 5, and 6 ... so it has a total of 21 dots.
