If you’ve searched for European vs American roulette, single zero roulette, double zero roulette, or roulette house edge, you’re likely trying to answer one practical question: Which roulette game gives me better value for my bets?
The good news is that roulette is easy to compare once you know what matters. European (and French) roulette typically uses a single-zero wheel with 37 pockets, while American roulette uses a double-zero wheel with 38 pockets. Payouts are the same, but the probabilities change, and that difference flows directly into the house edge.
The core difference: 37 pockets vs 38 pockets
Roulette outcomes are determined by the wheel pockets:
- European / French roulette: 37 pockets total (numbers 1–36 plus a single green 0).
- American roulette: 38 pockets total (numbers 1–36 plus a green 0 and 00).
That one extra pocket in American roulette might not feel like much, but it meaningfully changes the math on every bet you place.
Why payouts look identical, but your odds don’t
One reason roulette is so popular is that the payout table is simple and consistent across versions. For example:
- A straight-up bet (a bet on a single number) typically pays 35:1.
- A red/black bet typically pays 1:1.
- A dozen bet (1–12, 13–24, 25–36) typically pays 2:1.
Here’s the key: roulette payouts are generally set as if there were only 36 “true” number outcomes, but the wheel includes one or two extra green pockets. That’s what creates the casino advantage.
Straight-up bet example: 1/37 vs 1/38 win chance
Because European and American roulette have different pocket counts, the probability of winning a single-number bet differs:
- European (single zero): win probability is 1/37.
- American (double zero): win probability is 1/38.
The payout is still typically 35:1 in both games, so the expected value (your long-run average result) is better on the single-zero wheel.
Roulette house edge: European vs American (the numbers players care about)
If you want one metric to guide your choice, it’s the house edge:
- European roulette house edge: about 2.70%.
- American roulette house edge: about 5.26%.
This difference applies broadly across standard bets because both games keep the same payout structure while changing the underlying probability.
In practical terms, if you wager $100 total over time (not necessarily all at once), your expected loss is roughly:
- $2.70 on European roulette (2.70% of $100).
- $5.26 on American roulette (5.26% of $100).
No game guarantees a specific outcome in a short session, but the house edge is a strong indicator of which table gives you more play for your budget over the long run.
Quick comparison table: single zero vs double zero roulette
| Feature | European / French Roulette | American Roulette |
|---|---|---|
| Wheel pockets | 37 (0–36) | 38 (0, 00, 1–36) |
| Green pockets | Single green 0 | Green 0 and 00 |
| Straight-up payout | Typically 35:1 | Typically 35:1 |
| Straight-up win probability | 1/37 (≈ 2.70%) | 1/38 (≈ 2.63%) |
| Standard house edge | 2.70% | 5.26% |
| Expected loss per $100 wagered | ≈$2.70 | ≈$5.26 |
| Wheel number order | Different distribution than American | Different distribution than European |
Wheel layout vs table layout: what changes (and what doesn’t)
Players sometimes assume “European vs American roulette” means different betting options. In reality, the bet types are largely familiar across both versions, but the layout and the wheel can look different.
The table layout (the grid you bet on)
Most roulette tables include:
- Inside bets on specific numbers or small groups (straight-up, split, street, corner, six-line).
- Outside bets covering larger sets (red/black, odd/even, high/low, dozens, columns).
American tables often display both 0 and 00 at the top of the layout. European layouts show only a single 0.
The wheel layout (the order of numbers around the wheel)
European and American wheels typically use a different sequence of numbers around the wheel. This doesn’t change the mathematical odds of a fair spin, but it can change the feel of the game for players who track wheel outcomes or have personal routines.
French roulette rules that can improve your odds: en prison and la partage
Here’s where things get even better for players: some French roulette tables offer special rules on certain even-money bets (like red/black, odd/even, high/low) when the ball lands on zero.
These rules don’t usually apply to American roulette, and they are one reason many players actively seek out single zero roulette tables.
La partage (often written “la partage”)
With la partage, if you place an even-money bet and the ball lands on 0, you typically lose only half your bet (and get the other half back).
This can reduce the house edge on qualifying even-money bets from about 2.70% to about 1.35% on those bets, because the zero outcome is less punishing.
En prison
With en prison, if you place an even-money bet and the ball lands on 0, your bet is “imprisoned” for the next spin rather than losing immediately.
- If your bet wins on the next spin, you typically get your original stake back (rather than winning a full profit).
- If it loses on the next spin, you lose the stake.
Like la partage, this generally improves the value of even-money bets compared with standard European rules.
Tip: If you see a single-zero wheel and either en prison or la partage posted on the felt, you’re looking at one of the most player-friendly common roulette setups for even-money bets.
House edge vs volatility: what you’ll notice in real play
The house edge is a long-run average, but it has a real impact on the player experience:
- Lower house edge (European / French) generally means your bankroll tends to last longer for the same betting pattern.
- Higher house edge (American) typically means you’re paying more “cost per spin” in expected terms.
Volatility (swings up and down) still depends heavily on your bet type. Straight-up bets can produce big wins but have long losing stretches, while outside bets hit more often but pay less.
Common bets and how the zero (or double zero) affects them
A helpful way to understand roulette is to group bets into two categories and see how the extra pocket changes outcomes.
Even-money bets (1:1)
- Red / Black
- Odd / Even
- 1–18 / 19–36
These bets look close to 50/50, but the green pocket(s) are the reason they aren’t. On a European wheel, there’s one green outcome working against you; on an American wheel, there are two.
Inside bets (higher payouts, lower hit rate)
- Straight-up (35:1)
- Split, street, corner, six-line
These bets also suffer from the same structural issue: payouts are set in a way that creates an edge for the casino, and adding 00 makes that edge larger.
Practical advice: how to choose the best roulette table
If your goal is to maximize value while keeping the classic roulette experience, these selection tips can make a noticeable difference.
1) Choose single-zero roulette whenever possible
If you’re deciding between single zero roulette and double zero roulette, the single-zero option is usually the better deal. The standard house edge difference (about 2.70% vs 5.26%) is large in roulette terms.
2) Look for French rules on even-money bets
If you enjoy outside bets like red/black, try to find a French table that offers la partage or en prison. These rules can reduce the edge on qualifying bets compared to standard European roulette.
3) Confirm which wheel you’re actually playing
Casinos and online lobbies may label games differently, so check for the actual wheel pockets:
- If you see only 0, it’s a single-zero game.
- If you see 0 and 00, it’s American (double zero).
4) Keep your goals aligned with your bet type
- If you want frequent wins, outside bets will hit more often.
- If you’re chasing big payouts, inside bets like straight-up offer larger wins but lower hit rates.
Whichever style you like, choosing the better wheel (single zero) typically improves your long-run value without changing how you play.
FAQ: European vs American roulette
Is European roulette always better than American roulette?
In terms of expected value, yes in standard rules: European roulette’s house edge is about 2.70% versus about 5.26% for American roulette, because American adds the 00 pocket.
Do European and American roulette pay the same?
They typically do for standard bets (for example, a straight-up bet usually pays 35:1 in both). The difference is not the payout schedule; it’s the probability created by the number of pockets.
What is the expected loss per $100 in roulette?
Using the standard house edge as a guide, the expected loss is about $2.70 per $100 wagered on European roulette and about $5.26 per $100 wagered on American roulette. Actual short-term results can vary widely, but the long-run average favors the lower edge.
What’s the best roulette version for even-money bets?
Many players prefer French roulette with la partage or en prison for even-money bets because these rules can reduce the effective house edge on those specific bets compared to standard European rules.
Bottom line: the simplest winning move is choosing the right wheel
Roulette is all about small mathematical differences adding up over time. Since the payouts are usually identical, your biggest lever as a player is selecting the version with better odds.
- Pick European / French (single zero) for a lower typical house edge (about 2.70%).
- Prioritize tables offering la partage or en prison if you like even-money bets.
- Avoid American (double zero) when your goal is maximizing value, because the edge is about 5.26%.
When you choose the better wheel, you’re not changing the fun of roulette—you’re simply giving every spin more potential for your bankroll.
