Step 1 : Introduction to the question "What are the dots on dice called?"
...Each side of a standard die has a collection of depressions, or "pips." These pips are a set, showing different numbers on each side of the dice - numbers ranging from one to six. This is the standard norm for six-sided dice. The pips are usually painted a contrasting color to the actual color of the die. For example, a white die may have black or red pips. If the die is a traditional one, each of the numbers, when combined with the number of pips on its opposing side, will add up to seven. Source: Reference.com
