The first form of roulette was devised in 17th century France, by the mathematician Blaise Pascal, who was supposedly inspired by his fascination with perpetual motion devices. In 1842, fellow Frenchmen François and Louis Blanc added the "0" to the roulette wheel in order to increase house odds. In the early 1800s, roulette was brought into the U.S. where, to further increase house odds, a second zero, "00", was introduced. (In some forms of early American roulette the double-zero was replaced by an American Eagle.) In the 1800s, roulette spread all over both Europe and the U.S., becoming one of the most famous and most popular casino games. Some call roulette the "King of Casino Games", probably because it was associated with the glamour of the casinos in Monte Carlo. (François Blanc actually established the first casinos there).
A legend tells about François Blanc, who supposedly bargained with the devil to obtain the secrets of roulette. The legend is based on the fact that if you add up all the numbers on the roulette wheel (from 1 to 36), the resulting total is "666", which is the "Number of the Beast" and represents the devil.
