History of Craps
The game, first known as crapaud (a French word meaning "toad"), developed from a simplification of the Old English game hazard. It was first introduced in New Orleans by a gentleman named Bernard de Marigny de Mandeville.

When it landed in America, the rules and game became simpler. John H. Winn, an American dice maker, is known as the father of modern craps. Winn further developed the game to allow players to bet with the shooter or against him.

Dice themselves have evolved from wood, animal bones, and more expensive materials incuding ivory and precious stones. Today's dice are made from a hard cellulose material derived from cotton and are precisions cut form accuracy.

History of Roulette
Roulette is the French word for "little wheel". Blaise Pascal, a French scientist and philosopher, introduced a primitive form of roulette in the 17th century in his search for a perpetual motion machine. The roulette wheel is believed to be a fusion of the English wheel games Roly-Poly, Reiner, and Ace of Hearts.

In the 1800s, roulette spread all over Europe and the U.S., becoming one of the most famous and most popular casino games. In some forms of early American roulette wheels – as noted in the 1886 Hoyle gambling books – there were numbers 1 through 28, plus a single zero, a double zero, and an American Eagle.

As the game evolved, the double zero wheel remained the predominant style in the U.S.
