Roulette is a casino game that involves spinning a wheel with divisions numbered 1 to 36 and colored red and black. There is also a green zero (on American tables only).
Players wager by placing chips on the betting mats before the dealer spins the wheel. Each bet type has its own odds and payouts.
The origins of the game roullete are a subject of much debate. Some claim it was invented by French mathematician Blaise Pascal in the 17th century while others believe it was based on Chinese mystical board games that were brought to France by Dominican monks. The modern version of roulette, however, was developed in France around 1716. It combines elements of older games such as Roly Poly, Even-Odd and Biribi with the wheel structure of hoca and portique.
