Some gamblers believe that you can recover your losses by doubling your bet every time you lose. This is known as the Martingale system. The idea is that when you win, the win will be big enough to cover your previous losses. There are two problems with this system: You may run out of money before you win. You can only double your bet so many times because of table limits, and so occasionally you will hit the table limit before winning – and this will be very expensive.

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)

In Craps, winning or losing depends on a variety of different possible outcomes on any roll of the two dice. The two dice can produce many different number combinations; some can be made several ways, others only one way. For example, two dice can roll the number 6 as follows: 5/1, 4/2, 3/3, 2/4 and 1/5. But the number 2 can only be rolled one way: 1/1.

This system is a little more sophisticated, but the results can be as devastating as our old friend Martingale. It is a series of numbers, each of which is the sum of the last two numbers in the system, like this: 1-1-2-3-5-8-13-21-34-55-89-144. Advice about betting it varies, but one of the more common is to bet the series as you lose. If you win a bet, fall back one in the series If you win that one, start over, if you lose, continue on in the series.
