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.

Basic craps terminology: Shooter: the current dice thrower. Come-out roll: The shooter's first roll. Pass: If the shooter wins his game, by any means, he is said to "Pass". Don't Pass: The term used if the shooter loses. The following illustration depicts the left half of a craps table. The bets to the bottom right, therefore, are referred to as the center bets, as they are actually in the center of a full sized table.
