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)

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.
