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.

the first roll of the dice in a betting round is called the "come out" roll. Pass bets win when the come out roll is 7 or 11, while pass bets lose when the come out roll is 2, 3, or 12. Don't bets lose when the come out roll is 7 or 11, and don't bets win when the come out roll is 2 or 3. Don't bets tie when the come out roll is 12 (2 in some casinos; the "bar" roll on the layout indicates which roll is treated as a tie)
