The game of Craps revolves around dice. Wagers are made upon the result of a single roll, or a series of rolls, of a pair of dice. Craps is a game of probabilities and odds, so any discussion of Craps will benefit by a brief explanation of the probabilities involved. Since the game uses two dice, a shooter (the person rolling the dice) can roll any number between 2 and 12. It is important to understand that some numbers are more likely to appear than others on a single roll of the dice.

Don't Pass Line Bet - The reverse of the Pass Line bet. You are betting that the first role of the dice will not add up to 7 or 11. A 2 or 3 wins. A 12 causes a "Push" or "Standoff" where no one wins. If a "Point" is established, you are betting that the shooter will not "Make" or role his or her "Point" again before rolling a 7. Come Bets - This bet is made after the "Point" has been established and is exactly like the "Pass Line" bet. You win if the "Shooter" roles a "Natural" 7 or 11 and lose on 2, 3, or 11, called "Craps." You place your wager in the area marked "Come" on the craps table. Your wager remains here unless a "Point" number is rolled. The dealer then moves your wager to the number that was rolled on the table. This same number must be rolled again before a 7 comes for you to win.

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.
