Casino game

Roulette

Roulette is a casino game named after the French word meaning little wheel. In the game, players may choose to place bets on either a single number, various groupings of numbers, the colours red or black, whether the number is odd or even, or if the numbers are high (19–36) or low (1–18).

To determine the winning number and colour, a croupier spins a wheel in one direction, then spins a ball in the opposite direction around a tilted circular track running around the outer edge of the wheel. The ball eventually loses momentum, passes through an area of deflectors, and falls onto the wheel and into one of 37 (single zero French/European style roulette) or 38 (double-zero American style roulette) coloured and numbered pockets on the wheel.
