Soldiers in the Roman Legions used to shave down pig knuckles into the shapes of cubes, and toss them onto their inverted shields as a form of entertainment while in camp. Hence we get the term "to roll the bones". We do know that the game we know today as "craps" came to the United States from Europe.

Craps can be an intimidating game for the beginner. The table seems to have about a hundred different kinds of bets. Critical to the understanding of craps is that it is a game of rounds. The first roll in a round is called the come out roll. Sometimes the outcome of a round will be determined on the come out roll. In particular a 2, 3, 7, 11, or 12 on the come out roll immediately ends a round. If any other total is rolled (4, 5, 6, 8, 9, or 10) that number is called the point. The dealer will place a white puck on an area of the table to designate what the point is, in case you forget. If a point is rolled the dice will be rolled continuously until the same point is rolled again or a 7.
