The player who's current go it is, is called the shooter. The shooter wins if he rolls a 7 or 11 and this is entitled 'Natural' and he loses if he rolls a 2, 3 or a 12. This is known as 'craps' and it is where the name gets its name from. Rolling any of the remaining numbers (4, 5, 6, 8, 9 or 10) is known as the 'point'. If the shooter achieves point on his first roll, he must roll again, if he achieves point again, then rolls again and rolls a 7 then he wins. If a 7 is rolled after the first point then the shooter loses and the dice are passed on to the next person. The next person will then become the shooter.

The correct payoff for odds bets varies from point number to point number, depending on the odds of a 7 being rolled before a particular point is repeated. The payoff formula is the same whether you take single odds, double odds, or more. Correct odds payoffs are as follows: Points 4 and 10 pay 2-to-1 Points 5 and 9 pay 3-to-2 Points 6 and 8 pay 6-to-5 As an example, suppose you bet $1.00 on the pass line and establish a point of 4 in a casino that offers double odds. You now have the option of taking the adds for an additional $2.00. (You can wager a lesser amount or choose not to take any odds at all)

The shooter, or anyone wishing to bet that the shooter will win, places his bet "on the line" (in the area marked "Does Pass," "Line," or "Win" on various layouts) Anyone betting against the shooter places his bet in the area marked "Don't Pass." Anyone wishing to bet on a special contingency, such as that craps (2, 3, or 12) will or will not be thrown on the next roll, places his bet in the appropriate space on the layout; such bets are called proposition bets. The house maintains a mathematical advantage on all bets of about 1.4 percent, higher on certain layouts and special bets.

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.

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.
