Roulette is played by placing bets on a spinning wheel that contains numbered pockets, typically ranging from 0 to 36 in European Roulette or 00 to 36 in American Roulette. Players place their chips on a betting layout that corresponds to their chosen numbers or types of bets, such as single numbers, groups of numbers, or colors. Once all bets are placed, the dealer spins the wheel in one direction and rolls a ball in the opposite direction. The ball eventually lands in one of the numbered pockets, determining the winning number. Players who bet on that number or applicable categories receive payouts based on the odds associated with their bets.
