Popular in casinos, back alleys, and military barracks all over the world. A player rolls two dice. On this first roll, the "come-out roll", they win on a 7 or 11, or lose on a 2, 3, or 12. If they roll another number, it becomes their "point"; they continue to roll until they either roll that number again (in which case they win) or roll a 7 (in which case they lose). The wagering system varies depending on where you play and whether you have a casino-style layout.
