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.

Just as the come wager resembles the pass line bet, the don't come wager resembles the don't pass line wager. At any point in a game can a don't come wager be made by placing chips on the Don't Come Bar. The next dice roll immediately thereafter serves as the come-out roll for that particular wager. If the come-out roll comes up a 7 or 11, the bet loses. If it comes up a 3, the bet wins. All other numbers rolled are considered point numbers, which if rolled again before rolling a 7 or 11, will cause the don't come wager to lose. (If the point number is established, the dealer will move the wager to the corresponding box number on the craps table) Rolling a 7 or 11 before the point number is hit again, will produce a winning don't come bet.
