What is "roulette"?
Roulette is a popular casino game that involves a spinning wheel with numbered slots and a small ball. Players place bets on where they think the ball will land after the wheel is spun. The wheel has 37 or 38 numbered slots, depending on the version, with numbers ranging from 0 to 36. Players can bet on specific numbers, groups of numbers, or whether the ball will land on red or black. Once the wheel stops, the number where the ball lands determines the winning bets. Roulette is known for its excitement and variety of betting options.
