The Game of Kings
Roulette is likely to have originated in China 2,000 years ago as a game of religious character which helped predict one's destiny. Having arrived in Europe, it provided philosopher Blaise Pasqual with incentives to develop his theory of probability. Today there are two types of games in existence. The rules are the same for both. The only difference is that the winning number is indicated with a small metal marker called a "dolly" at American Roulette. At French Roulette, however the croupier shows the winning number with the rateau.
