How Many Numbers Are on a European Roulette Wheel?

There are 37 numbers on a European Roulette wheel. The extra number is the green zero, which gives the house an edge over the player. If you bet on a single number, you have a 1 in 37 chance of winning. The probability of winning is lower if you bet on multiple numbers, because your chances of hitting the right number are spread out over more numbers.

PRO TIP:European Roulette Wheels contain 37 numbers – 0-36. The number 0 is green, while the remaining numbers are divided equally between the colors red and black.

For example, if you bet on red, you have a 18 in 37 chance of winning, because there are 18 red numbers on the wheel. But if you bet on 10 red numbers, your chances of winning are only 1 in 10.
