The Difference Between European And American Roulette

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 Extra Green Zero

A European roulette wheel features 37 pockets in total: the numbers 1 through 36, plus a single zero (0).


While the payouts remain exactly the same, your odds of hitting a specific number decrease on the American wheel.

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.

Special European Roulette 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%.
