Evidence suggests Craps may have originated and evolved during the ancient Roman Empire. Roman soldiers used to carve the knuckles of pigs into cubes and would play with them by tossing them over their shields as a game while in camp. The term To Roll the Bones originated from here. Other theories claim Craps originated in the Middle Ages with the people in the Arabian deserts as they used to play a game that was quite similar to Craps called Hazard or Azzahr.
The definitive rules of this game were founded in the early 1700s by Montmort. The roll that had the lowest value was referred to as crabs. While many believe this is where Craps got its name, others believe the word evolved from Crapeaud, which is the French word for toad. Other theories claim the French were trying to reclaim the game as their own and they took the English word Crabs and spelled it in French as Crabes. In the 1700s, the game succeeded in crossing the Atlantic Ocean and reached Acadia, the French Colony.
In 1755, the French lost their colony and the people of Acadia relocated to Louisiana. They brought the French game Crabes to Louisiana, but the game was called Creps or Crebs. By the year 1842, the terms Craps started to be the dominant term and is still the name that is prevalent to this day.
During the World War II, the Street version of the game was very popular and was played by the soldiers who used their blankets as the gaming surface. There was no wall to stop the dice from rolling out so they used blanket rolls to prevent the dice from falling.
It is also important to note that the Craps version in modern America was brought by Bernard Xavier Philippe, who was a politician and a gambler. His version of Craps had a flaw that allowed players to exploit the game by taking advantage of the wagering system or by using fixed dice. This problem was fixed by John H Winn who introduced a new wagering option: Do Not Pass. This wagering option is used to this day in any casino that offers craps to its players around the world.
