European vs American Roulette Wheels
The fundamental difference between roulette styles lies in the number of green zero pockets on the wheel rim:
- European Roulette: Features 37 pockets numbered 0 through 36. The presence of a single green zero establishes a house edge of 2.70%.
- American Roulette: Features 38 pockets numbered 0, 00, and 1 through 36. The additional double-zero increases the house edge to 5.26%.
- French Roulette: Utilizes the European single-zero wheel with special rules such as "La Partage" or "En Prison", which return half the stake on even-money bets when zero lands.
