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 notation on both dice may be interpreted as either 0 or 100, depending on the game rules. The "d1000" (using three 10-sided dice) is occasionally also seen, although it is more common in wargames than role-playing games. A number of notational strategies exist for discarding only certain types of results. Some games extend the standard notation to A"d"X"(k"Y")+"B where, in addition to the above, Y is the number of dice kept (k) from the roll. Whether the dice omitted are the highest, lowest, or the player's choice depends on the game in question. 7th Sea and Legend of the Five Rings
