Roulette is universally recognized as one of the most iconic and popular games in casino history.

Choosing the wrong version of roulette is the most common and costly mistake new players make.
The Difference is in the Zeros
The American wheel, however, has 38 pockets: numbers 1 through 36, a single zero (0), and a double zero (00).

This single extra pocket on the American wheel drastically alters the mathematical probabilities of the game.

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.
Special European Roulette 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.
