Unlike card-based games such as blackjack, roulette is immediately accessible to all players because it requires no specific skills to play. The game has two major components: the roulette table and the roulette wheel. The table layout is divided into “inside” spaces numbered 1-36 and 0 (plus OO in the case of American Roulette) and “outside” spaces labelled 1-12, 13-24, 24-36, 1-18, 19-36, Even, Odd, Black and Red. The wheel has 37 or 38 numbered slots. A dealer, or croupier, spins the wheel in one direction and spins a ball in the other direction. Players place their bets as the wheel whirls. Then, acting like a random number generator, the wheel slows down until the ball drops into a slot and the outcome is revealed.
