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.

If the shooter is winning, the dice are not passed on. The dice are only passed to the next player if the shooter sevens-out (rolls a seven) or decides not to continue rolling. In the Internet version of Craps, the player loses if there is a seven-out and can end the game at any time provided there are no bets placed. Pass Line and Don't Pass Line bets are made on the shooter's "Come Out" roll. All other bets are placed after the come out, once a "point" has been determined, and work independent of the "pass line" and "don't pass" bets.
