When the "shooter" rolls a 7 or 11 on the first throw (The Come-out roll) it is refer to as a "natural" and an automatic win. On the other hand, if 2, 3 or 12 rolls, it is called, "craps" and you lose your Pass Line bet. Any other number (4, 5, 6, 8, 9, or 10) becomes your "Point." You win if the "Point" repeats before 7 rolls, and you lose if 7 show before your "Point." Is made. Place these bets in the area marked "Pass Line" on the layout.

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".

According to Richard Epstein, craps is descended from an earlier game known as Hazard, that dates to the Middle Ages. The formal rules for Hazard were established by Montmort early in the 1700s. The origin of the name craps is shrouded in doubt, but it may have come from the English crabs, or from the French Crapeaud (for toad)
