Roulette is a casino game where people bet on a number. There are several betting combinations that bring different odds and payouts for winning bets. The bet types are divided into inside and outside bets.
The roulette wheel has thirty-six compartments painted alternately red and black, with a green one numbered 0. On American tables an additional two green pockets carry the numbers 00, making this variant of the game a worse proposition financially than its European counterpart.
