There are several variants of roulette, depending on the layout of the wheel and the structure of the bets. The most important variation is between American Roulette and European Roulette.
American Roulette has two zero pockets (0 and 00). European Roulette has only one zero pocket (0), which gives a lower house edge on the so called “even money” bets. This is a good thing! See our article on roulette odds.
Below we have listed and described the major variants of the game.
