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)

Once the shooter establishes a "Point" your "Don’t Pass" bet stays in action, win until the shooter rolls a 7 or make his/her "Point". a "Don’ Pass" bet wins if the shooter fails to make his "Point", but loses if the shooter does make the "Point". You can take odds on a "Don’t Pass" bet.
