Craps the dice to hit the back wall and are generally lenient if at least one die hits the back wall. Both dice must be tossed in one throw. If only one die is thrown the shot is invalid. A come-out roll of 2, 3 or 12 is called "craps" or "crapping out", and anyone betting the Pass line loses. On the other hand, anyone betting the Don't Pass line on come out wins with a roll of 2 or 3 and ties (pushes) if a 12 is rolled. Shooters may keep rolling after crapping out; the dice are only required
Dice control to shooting. It purports to involve limiting the rotational characteristics of the dice. The theory is that if the dice are properly gripped and tossed at the correct angle they will land just before the back wall of the craps table, then gently touch the wall, greatly increasing the probability of their remaining on the same axis. If executed properly and consistently this technique would be able to change the game's long-term odds from the house's favor to the player's favor.
