In the betting game known as craps, the player starts by rolling two dice and combining their values. On the first roll, 7 or 11 is an automatic win (a “pass”), while a roll of 2, 3, or 12 is an automatic loss (“craps”). Every other roll is called a “point” and allows the roller to keep rolling in an effort to match that point.
