In Craps, the shooter is the person rolling the dice. At the start of each new game, the shooter makes the "come out roll" with the two dice, which determines the “point” for the subsequent roll(s) of the game. The possibilities for the "come out roll" of the dice are to either "crap out" (a two, three, or twelve on the dice) or to "set the point" (a four, five, six, eight, nine, or ten).
If the shooter rolls a seven or eleven on the come-out roll (resulting in an instant win for the shooter and all 'right bettors'), then the round ends immediately. If the shooter rolls any other number, that number is “established” as the “point” for the remainder of the round. The shooter then proceeds to roll the dice until he rolls the same point number again, (known as making a “pass”) resulting in an end to the game, or if he rolls a seven (known as a "seven out"), resulting in an immediate end of the game.
In between the come-out roll and either of the end points, a variety of other number combinations can be rolled, and players bet on certain outcomes on each roll. Some of the more popular types of bets include pass line bets, don’t pass line bets, come line bets, don’t come line bets, hard way bets, and a variety of single-roll proposition bets.
