Roulette is a casino and gambling game named after the French word meaning “small wheel”. In the game, players may choose to place bets on either a number, a range of numbers, the color red or black, or whether the number is odd or even.

To determine the winning number and color, a croupier spins a wheel in one direction, then spins a ball in the opposite direction around a circular track of the wheel. The ball eventually loses momentum and falls on to the wheel and into one of 37 (in European roulette) or 38 (in American roulette) colored and numbered pockets on the wheel.
