European vs. American Roulette: Which is Better?

Roulette is one of the most iconic and visually thrilling games available on any casino floor.

The variation you decide to play has a massive impact on your mathematical chances of walking away a winner.

The Green Zero: The House’s Secret Weapon

On a European table, the presence of the single zero is what prevents the even-money bets from being perfectly 50/50.

Conversely, the American layout adds an extra green slot—the double zero—significantly altering the math of the game.

• European roulette has a house edge of 2.70%, which is relatively standard for a table game
• American roulette has a house edge of 5.26%, making it one of the worst bets on the entire floor
• Always check the wheel before placing a chip to see how many green slots exist

Advanced European Roulette Rules

In addition to the better wheel layout, some European (often called French) tables offer incredibly favorable special rules.

The ‘En Prison’ rule allows your even-money bet to remain ‘in prison’ for the next spin if a zero hits, giving you a second chance.

By simply choosing the European wheel, you instantly double your expected mathematical longevity at the casino.
