Roulette, French for "small wheel", the King of Casino Games, is a popular and highly esteemed gambling game, as its moniker teaches us. Roulette players bet on which slot of the wheel - a rotating disk - the small ball will land and rest on. It involves a classic table layout of numbers in red and black, and various betting options.

The game begins with the croupier, the roulette game's dealer. The croupier spins a special wheel in one direction, and tosses a small ball into the tilted surface in the opposite direction. While the players watch for where the ball will eventually land and rest, bets are accepted over what color and number pocket it will land on. This is the outcome that determines winnings.


A whole cycle of a game, including the bets that were placed during that cycle. Each casino game has its own definition of a round: in roulette it is a spin of the wheel and the bets on the outcome; in poker it is the entire process until the winner takes in the pot.
