One of the three main roulette variants, American roulette features 38 numbered pockets including “0” and “00”. Having a double zero increases the house edge to 5.26%. One further peculiarity of American roulette is that it has no call bets, and this makes the gameplay somewhat easier. Since this roulette variant is well-loved by millions, the game has been developed by NetEnt, Evolution Gaming, Microgaming, and other software suppliers, each adding some special features (Hot/Cold numbers, statistics, autoplay, etc.) and minor variations to overall design, range of table felt colors or wheel/betting grid location.
