American vs European vs French Roulette

Three Wheels, Three Experiences

Walk into any casino worldwide and you'll encounter at least one of three roulette variants. They look similar—a spinning wheel, a ball, numbered pockets—but the differences between them matter significantly to your odds.

American Roulette: The Double-Zero Disadvantage

American roulette features 38 pockets: numbers 1–36, a single zero (0), and a double zero (00). That extra pocket is the critical difference.

House edge: 5.26% on nearly every bet.

The double zero doesn't add excitement—it subtracts value. For every $100 you wager over time, you return $94.74 on average. American roulette is found primarily in North American casinos, where it's the default.

European Roulette: The Player-Friendly Standard

European roulette uses 37 pockets: numbers 1–36 and a single zero (0). Remove the double zero and the math improves substantially.

House edge: 2.70%.

The same bet that costs you 5.26% in American roulette costs you 2.70% here. All else being equal, always choose European roulette over American when both are available.

French Roulette: The Best Odds Available

French roulette uses the same 37-pocket wheel as European but adds two rules that further reduce the house edge on even-money bets:

La Partage: When the ball lands on zero, you recover half your even-money bet automatically.

En Prison: Alternatively, your bet is "imprisoned" on the layout. If it wins the next spin, you recover your full stake.

Both rules effectively halve the house edge on outside bets.

House edge with La Partage: 1.35% on even-money bets.

The Verdict

|---------|---------|-----------------|-----------|

Variant	Pockets	Base House Edge	Best Case
American	38	5.26%	5.26%
European	37	2.70%	2.70%
French	37	2.70%	1.35% (La Partage)

The choice is clear: French roulette with La Partage is statistically the best roulette you can play. European comes second. American roulette is the worst value for the player.

Does the Wheel Layout Matter?

The physical arrangement of numbers on the wheel differs between American and European/French. Some players study wheel sectors for their "drop zone" biases. In a truly random game, layout doesn't matter. But if you're exploring wheel bias, the European layout is more studied.
