The most common craps bet. Wins immediately if a 7 or 11 is rolled; loses on a 2, 3 or 12; otherwise wins if the number rolled is rolled again before a 7.
Part of the dealer expression "six ace, end of the race", meaning that the shooter has rolled a 7.
An even-money bet that an 8 will be rolled before a 7. A sucker bet since a place bet on the 8 wins exactly the same way, but pays more.
During a come-out roll, odds bets from the previous round neither win or lose when they are "off". Players can request that odds be "on"/"working" or "off"/"not working" at any time.
