The casino game of Craps is played with a set of two perfectly balanced dice with each die having six white dots numbered 1 through 6. The game is played by tossing the dice from one of the short ends of the table to the other (make sure that both die hit the opposite side wall of the table) Payoffs are made based on the number combination displayed when the dice come to rest.

The shooter, or anyone wishing to bet that the shooter will win, places his bet "on the line" (in the area marked "Does Pass," "Line," or "Win" on various layouts) Anyone betting against the shooter places his bet in the area marked "Don't Pass." Anyone wishing to bet on a special contingency, such as that craps (2, 3, or 12) will or will not be thrown on the next roll, places his bet in the appropriate space on the layout; such bets are called proposition bets. The house maintains a mathematical advantage on all bets of about 1.4 percent, higher on certain layouts and special bets.
