The American Roulette Wheel features two zeros (0, 00) in addition to 1 through 36, which totals 38 numbers altogether. In contrast, the European Roulette Wheel features only one zero (0), which means that there are 37 numbers in total. This difference represents a significant difference in the house edge between the two types of wheels. On a European roulette wheel the house edge is approx. 2.70% - much lower than the American wheel at 5.26%.
