Roulette is a game of chance where a ball is spun on a wheel with numbered pockets. The odds of winning on a single number bet in European roulette, which has 37 pockets (numbers 1-36 and a green 0 pocket), is 1 in 37 or 2.7%.
The odds of winning on a single number bet in American roulette, which has 38 pockets (numbers 1-36, a green 0 pocket, and a green 00 pocket), is 1 in 38 or 2.63%. The odds of winning on any other bet, such as a color bet or a range of numbers, will be different and can be calculated by dividing the number of pockets that correspond to the bet by the total number of pockets on the wheel.
