In Craps, winning or losing depends on a variety of different possible outcomes on any roll of the two dice. The two dice can produce many different number combinations; some can be made several ways, others only one way. For example, two dice can roll the number 6 as follows: 5/1, 4/2, 3/3, 2/4 and 1/5. But the number 2 can only be rolled one way: 1/1.

Dice game, most popular in American gambling houses. Any number may play. Each person in turn may, as the shooter, cast two matched dice in attempting to roll a winning combination. Before his first throw the shooter puts up a stake, and the other players fade it, i.e., bet against the shooter up to the amount of the stake. The shooter must withdraw any part of his stake that is not faded. If he wins, he may continue to shoot and bet again, as much or as little as he wants; or he may give up the dice. If the shooter loses, the other players take away double the amount they faded. The other players also may bet among themselves as to whether the shooter will win or lose in the next series of throws or whether certain numbers or combinations will appear. In some games, such as bank craps , players may bet only against the house.
