Roulette is universally recognized as one of the most iconic and popular games in casino history.
Understanding the subtle differences between the wheels is crucial for maximizing your chances of winning.
The Difference is in the Zeros
The single most important difference between the two games lies entirely in the number of green zero pockets.
The addition of the 00 pocket effectively doubles the casino's built-in mathematical advantage over the player.
- 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
With a house edge of 2.70%, European roulette is relatively fair compared to many other casino games.
Statistically, for every $100 you wager, you expect to lose $2.70 on European and $5.26 on American.
The En Prison and La Partage Rules
The "En Prison" rule "imprisons" your bet for the next spin if the zero hits, giving you a second chance.
If these special rules are in effect, the house edge on even-money bets drops to an incredible 1.35%.
| Version | Zero Pockets | House Edge |
|---|---|---|
| European | One (0) | 2.70% |
| American | Two (0, 00) | 5.26% |
Online casinos almost always offer both, so be vigilant and always click on the European wheel.
