Roulette is a game named after a French diminutive for little wheel. In the game, players may
choose to place bets on either a single number or a range of numbers, the colors 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 tilted circular
track running around the circumference of the wheel. The ball finally comes to rest in one
of the red or black, numbered pockets into which this disk is divided, thus determining the
winning bets. Following is the composition of roulette.
