Roulette is a popular casino game that involves a spinning wheel and a betting table. The game is played with a small ball that is spun around the wheel, and players bet on where the ball will land.
The roulette wheel contains numbered pockets from 0 to 36 （in European roulette） or 00 and 0 to 36 （in American roulette）. Players place their bets on the table layout, which corresponds to the numbers and colors on the wheel.
There are two main types of bets in roulette: inside bets and outside bets. Inside bets are placed on specific numbers or small groups of numbers, while outside bets cover larger groups of numbers such as red/black, odd/even, or dozens.
After all bets are placed, the dealer spins the wheel and releases the ball. When the ball comes to rest in one of the numbered pockets, the winning number is determined. All losing bets are collected, and winning bets are paid according to the payout odds.
The house edge varies between different roulette versions. European roulette has a house edge of 2.7%, while American roulette has a higher house edge of 5.26% due to the additional double zero pocket. |
