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

Understanding the difference between the American and European variations is the most crucial strategy in the game.

The Green Zero: The House’s Secret Weapon

A standard European wheel contains only one green slot (the 0), giving the house its mathematical advantage.

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

Why French Roulette is Even Better

Certain high-end European tables utilize the ‘La Partage’ rule, which further reduces the house advantage.

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.
