Roulette is universally recognized as one of the most iconic and popular games in casino history.
European and American roulette may look nearly identical to the untrained eye, but the math differs wildly.
The Difference is in the Zeros
The single most important difference between the two games lies entirely in the number of green zero pockets.
This single extra pocket on the American wheel drastically alters the mathematical probabilities of the game.
- The extra number changes all probability calculations
- The betting layout is slightly larger on the American table
- European tables often use a different chip system
Why the House Edge Matters
Because the European wheel has only one zero, the house edge is a very reasonable 2.70%.
There is absolutely no mathematical justification for ever choosing to play American roulette if European is available.
The En Prison and La Partage Rules
Some European, and particularly French, roulette tables offer player-friendly rules called “La Partage” or “En Prison.”
This makes French roulette one of the most mathematically favorable table games on the entire casino floor.
| Version | Zero Pockets | House Edge |
|---|---|---|
| European | One (0) | 2.70% |
| American | Two (0, 00) | 5.26% |
The conclusion is incredibly simple: you should always seek out and exclusively play European or French roulette.
