Spin the roulette wheel and put your skills to the test without risking real money. American Roulette is similar to European Roulette, but instead of only one zero, it has two zeros (0 AND 00). This additional zero makes for a higher house edge on single number bets at 5.26%. American Roulette is an easy game to play. The wheel spins in one direction while the ball spins along a slanted track around it, eventually falling into one of 38 slots on the wheel with number and colour combinations (red/black).
