What is Roulette?

Roulette is a casino game played with a rotating wheel and ball. Players can make a variety of bets on a single number, different groups of numbers, red or black, odd or even, and high (19-36) or low (1-18).

Each player has until the croupier announces no more bets to place their chips on the table map (aka layout). Then the croupier throws the ball into the roulette wheel.
