The correct payoff for odds bets varies from point number to point number, depending on the odds of a 7 being rolled before a particular point is repeated. The payoff formula is the same whether you take single odds, double odds, or more. Correct odds payoffs are as follows: Points 4 and 10 pay 2-to-1 Points 5 and 9 pay 3-to-2 Points 6 and 8 pay 6-to-5 As an example, suppose you bet $1.00 on the pass line and establish a point of 4 in a casino that offers double odds. You now have the option of taking the adds for an additional $2.00. (You can wager a lesser amount or choose not to take any odds at all)

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)
