If you want to know whether or not you’re playing a single zero or double zero game, just take a look at the roulette wheel. Though these types of wheels are the standard in those areas, there’s no law saying you can’t play single zero roulette in America or double zero roulette in Europe. American roulette, also known as double zero roulette, has the numbers 0-36 just like the European wheel, but includes a “00” space that increases the number of potential roulette outcomes from 37 to 38.īecause single zero roulette games are called European roulette, you may assume that all roulette games in Europe have one zero space and all games in America have two.

European or single zero roulette wheels have just 37 numbers that could turn out winners, the numbers 0-36. In Europe, where roulette originated, the game’s wheel has a green space labeled “0.” When American roulette wheels were redesigned to add another green slot, the “00” slot, the house edge increased from 2.7% to 5.26%. The addition of a single space on the wheel has a significant impact on the casinos’ edge. The difference in house edge between a single zero roulette wheel and a double zero roulette wheel is considerable.

A single zero roulette game uses a roulette wheel with just one “0” space, instead of the “0” and “00” spots on American style roulette wheels. Single zero roulette is another name for European style roulette.
