Roulette is one of the most popular casino games worldwide, known for its simple yet exciting gameplay. The game features a spinning wheel with numbered pockets and a small ball that determines the winning number.
The roulette wheel contains either 37 or 38 pockets, depending on the version. European roulette has numbers 1 through 36 plus a single zero （37 pockets）, while American roulette has numbers 1 through 36 plus both a single zero and a double zero （38 pockets）.
Players place their bets on the roulette table before the wheel is spun. Bets can be placed on individual numbers, groups of numbers, colors （red or black）, odd or even numbers, or high （19-36） or low （1-18） numbers.
Once all bets are placed, the dealer spins the wheel in one direction and the ball in the opposite direction. As the wheel slows down, the ball eventually falls into one of the numbered pockets, determining the winning number and color.
The payout odds vary depending on the type of bet placed. Straight up bets on single numbers pay 35 to 1, while even money bets （red/black, odd/even） pay 1 to 1. The house edge differs between versions, with European roulette having a 2.7% edge and American roulette having a 5.26% edge due to the additional double zero. |
