Roulette

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.
