The remaining pockets are marked with numbers 1 through 36. There is one zero pocket, coloured in green. Unlike American roulette, where there are two zero pockets on the wheel, in European roulette, the wheels have only 37 pockets.
The main difference between American and European roulette lies in the number of pockets on the wheel and on the betting layout, respectively. What’s the difference between the two? The rules and the betting options in the two variants are roughly the same with a few small exceptions. European roulette is played predominantly in landbased gambling venues throughout Europe but due to the game’s immense popularity, all well-known online casino operators have added it to their gaming portfolios, alongside the American variation.
