Craps is a casino dice game. Craps is a simplification of the Old English game hazard. In Craps, players wager money against the casino on the outcome of one roll, or of a series of rolls of two dice. Craps can also be played in less formal settings and is said to be popular among soldiers. In such situations, side bets are more frequent, with one or several participants covering or "fading" bets against the dice.
