The origins of this casino game are complex and may date back to the Crusades, receiving influence by French gamblers, who probably first brought it to New Orleans, where its popularity is thought to have spread through the African-American community. Craps players wager money against the casino on the outcome of one roll, or of a series of rolls of two dice.
Craps is a casino game played by 1 or more players. The player rolling the dice is called the "shooter". The game is played in rounds, with the first roll of a new round called the "come-out roll."
On the come-out roll if the total of the two dice is 7, 11, 2, 3 or 12, the round ends immediately and the shooter must roll another come-out roll. A result of 2, 3 or 12 is called 'craps' while a result of 7 or 11 is called a 'win' or a 'natural'. When any other number (4, 5, 6, 8, 9, or 10) is rolled on the come-out roll, this number becomes what is called the point. If a point is established then the shooter will re-roll the dice continuously until either a 7 is rolled, or the point is rolled again. If the shooter rolls the point again, the round ends and the game starts over with the same shooter rolling another come-out roll. If the shooter rolls a 7 instead of the point, this is called a 'seven-out' and the round ends.
