European Roulette
This is the most common roulette game across online casinos that is made popular by the low house edge it offers. In this version of the game, the roulette wheel has 37 pockets, numbered from 0 to 36. The 0 brings the house edge down to a low of 2.7%.
American Roulette
Made popular in the casinos of Las Vegas, the American variant of the game adds a double 0 pocket to the wheel. Although it doesn’t change the rules of the game, the additional pocket does affect players’ odds of winning. In this case, the house edge sits at 5.26%.
