Casino roulette is one of the most popular and iconic casino games worldwide. The game involves a spinning wheel with numbered pockets and a small ball that determines the winning number.
The roulette wheel contains either 37 pockets （European roulette） numbered 0-36 or 38 pockets （American roulette） numbered 0-36 plus an additional 00 pocket. The numbers alternate between red and black colors, with the zero pockets typically colored green.
Players place their bets on the roulette table layout 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 releases 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 dealer then clears losing bets and pays winning bets according to the payout odds. Different types of bets have different payout ratios, with straight-up bets on single numbers paying 35:1 being the highest paying bet.
Understanding the house edge is crucial - European roulette has a 2.7% house advantage while American roulette has a 5.26% house advantage due to the additional double zero pocket. |
