This is known as the cancellation system. Pick a series of numbers, say 1,2,3,4,5. Your first bet is the total of the two numbers on the end, or 6 units in this case. If you lose it, you cancel out the 1 and the 5, add the six to the end of the series and bet the 6 and the 2, for a total of eight units bet. Lose that one and you add the eight to the series, cancel the 2 and the six and bet a total of 11 (3+8) and so on. If you win, you proceed to the inside numbers until they are all cancelled out. Again, a loser, but an insidious one.

On the "Come Out" roll, the "Pass Line" bet wins if the shooter rolls a 7 or an 11. The bet loses automatically if the shooter rolls 2, 3 or 12. This is known as "rolling craps". If the shooter rolls 4, 5, 6, 8, 9 or 10 the shooter must roll this same number again (to win) before rolling the number 7. Rolling any of these numbers on the "Come Out" roll is called "establishing the "Point". Any number so rolled is thereafter referred to as the "Point".

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.
