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.

This system is a little more sophisticated, but the results can be as devastating as our old friend Martingale. It is a series of numbers, each of which is the sum of the last two numbers in the system, like this: 1-1-2-3-5-8-13-21-34-55-89-144. Advice about betting it varies, but one of the more common is to bet the series as you lose. If you win a bet, fall back one in the series If you win that one, start over, if you lose, continue on in the series.
