Learning European vs. American roulette is key to understanding how to play the game. Even though there’s no fundamental difference between the mechanics of a European wheel and a U.S. roulette wheel, the house edge of one is nearly double the other.  

This guide breaks down the key distinctions between the two roulette types, including which one has better odds.

Key Differences Between American vs. European Roulette

The primary difference between European roulette vs. American roulette is the number of zero pockets.

An American roulette wheel features 38 numbers: 1–36, and two zero pockets (0, 00). The 1–36 pockets alternate between red and black, and both zero pockets are green. The double zero roulette wheel gives the house an edge of 5.26%, or a 94.74% return to player (RTP) rate.

A European roulette wheel features 37 pockets; 1–36, and one zero pocket. The single zero roulette wheel also features a green zero space and numbers that alternate between red and black. However, the key difference is the single zero. By removing the second zero from the wheel the house edge is nearly cut in half to 2.7%, or an RTP of 97.3%. The single zero makes European roulette more appealing, since it has better odds than American roulette.

On top of that, European roulette offers two optional rules that improve player odds: La Partage and En Prison. Both are applied when the ball lands on zero after even money bets like red/black or odd/even are placed. La Partage means that you only lose half your bet when the ball lands on zero, while En Prison places your bet on hold “in prison” and allows you to win it back on the next spin. Both La Partage and En Prison cut the house edge down even further to just 1.35%.

Does American Roulette or European Roulette Give the Best Odds?

When it comes to American vs. European roulette, European roulette has the best odds. The American version features two zero pockets, and the single-zero European version cuts the house edge in half. Risk tolerance is crucial in both versions, and we hope you can use this information to help you win more games.
