A roulette wheel is both a simple device and an elegant work of art. These polished mahogany bowls have always been the most recognizable feature of the game, and they are truly eye-catching sights on the casino floor itself. Computer graphics are no less than spectacular when it comes to the look of online roulette wheels. You will find two types of wheels online: single-zero and double-zero.

The European Wheel and Layout

The European or single-zero online roulette wheel features 37 slots and contains only one green 0 or ‘zero slot’. There is a House edge of only 2.70 percent on any given spin when you play the European wheel online. American roulette should always be avoided in favor of the European wheel.

Below is the typical 37 number betting layout that is found next to the European online roulette wheel.

The American Wheel and Layout

The American or ‘double-zero’ online roulette wheel features 38 slots with both the 0 and 00 green spaces. There is a House edge of 5.26 percent on all bets but one (the 0-00-1-2-3 combination bet at 7.89 percent) when you play American roulette, which is why the American roulette should only be played when playing the European online roulette wheel isn’t an available option.

Below is the typical betting layout that is found next to the wheel. You will find an interactive table similar to this one when you play online. The American online roulette wheel features 38 inside numbers.
