House Edge Explained: Differences Between European, American, and French Roulette
House Edge Explained: Differences Between European, American, and French Roulette
Roulette is one of the most iconic casino games in the world — a blend of luck, excitement, and simple strategy. But while the spinning wheel may look the same everywhere, there are actually several versions of the game, each with its own rules and odds. The three most common are European, American, and French roulette. The differences between them may seem minor, but they have a major impact on the house edge — the built-in advantage that ensures the casino always has the upper hand in the long run.
What Does “House Edge” Mean?
The house edge represents the average percentage of each bet that the casino expects to keep over time. It’s calculated as the difference between the true odds of winning and the payout offered to players. The lower the house edge, the better the game is for the player.
In roulette, the house edge depends mainly on how many pockets are on the wheel — and how the game handles the zero pockets. That’s where the three main versions differ.
European Roulette – The Classic and Most Balanced Version
European roulette is the most common version found in both land-based and online casinos across Canada and Europe. The wheel has 37 pockets: numbers 1 through 36, plus a single green zero (0). The green zero is what gives the house its edge, since it doesn’t belong to red/black or even/odd bets.
The house edge in European roulette is 2.7%, making it one of the most player-friendly casino games available. If you bet on red, your chance of winning is close to 50%, but not quite — the single zero slightly tips the odds in the casino’s favor.
American Roulette – The Extra Zero That Doubles the House Edge
American roulette looks almost identical to the European version, but there’s one key difference: it has 38 pockets. In addition to numbers 1 through 36 and a single zero (0), it also includes a double zero (00). That extra pocket increases the likelihood that the ball will land on a zero, which in turn increases the house edge.
In American roulette, the house edge is 5.26% — nearly double that of the European version. Over time, this means players lose more per dollar wagered. For that reason, American roulette is generally less favorable for players who care about maximizing their odds.
French Roulette – Subtle Rules That Benefit the Player
French roulette is very similar to European roulette, as it also features 37 pockets with a single zero. The main difference lies in the special rules that can reduce the house edge even further. Two unique rules make French roulette stand out:
- La Partage: If you place an even-money bet (like red/black or odd/even) and the ball lands on zero, you get half of your bet back.
- En Prison: In some versions, if the ball lands on zero, your even-money bet is “imprisoned” for the next spin. If your bet wins on the next spin, you recover your full stake.
These rules lower the house edge on even-money bets to about 1.35%, making French roulette the most favorable version for players who prefer simple betting strategies.
Comparison: Which Roulette Should You Choose?
| Variant | Number of Pockets | House Edge | Special Rules | |----------|------------------|-------------|----------------| | French Roulette | 37 | ~1.35% (on even-money bets) | La Partage / En Prison | | European Roulette | 37 | 2.7% | None | | American Roulette | 38 | 5.26% | Double zero (00) |
If you have the choice, French roulette offers the best odds mathematically. European roulette is a solid second option, while American roulette is best chosen for its atmosphere or availability — not for its winning potential.

Strategy and Responsible Play
Roulette is ultimately a game of chance, but understanding the rules and the house edge can help you make smarter decisions. Always choose the version with the lowest house edge, and set clear limits on how much you’re willing to spend. Roulette should be about entertainment, not profit.
For Canadian players, whether you’re spinning the wheel at a land-based casino in Montreal or playing online from home, knowing the differences between European, American, and French roulette can help you enjoy the game more — and play with confidence.
