The American roulette wheel has 38 numbers, including the numbers 1 to 36, a 0 ('zero') and a 00 ('double zero'). The European roulette wheel has 37 numbers, including the numbers 1 to 36 and a 0 ('zero'). In both games the house still pays 35 to 1 on a straight (one number) bet. This means European roulette offers better odds than American roulette. The house edge on all bets (except the five-number line bet) in American roulette is 5.26%, compared to 2.63% in European roulette. If you are planning to play roulette, always play single-zero European roulette, when offered a chance.
