European vs American Roulette: The core factual differences
At a glance, the biggest difference is the number of zero pockets on the wheel. That single detail changes the math behind every bet.
| Feature | European Roulette | American Roulette |
|---|---|---|
| Zero pockets | Single zero (0) | Double zero (0 and 00) |
| Total pockets | 37 (1–36 plus 0) | 38 (1–36 plus 0 and 00) |
| Typical house edge | About 2.7% | Around 5.26% |
| Rules that can improve even-money bets | Often may include la partage or en prison (table-dependent) | Typically not offered |
Those house-edge numbers aren’t marketing claims; they come directly from the probability of landing on the zero pocket(s) versus a player bet’s true odds.
Roulette house edge comparison: the math behind single zero vs double zero
Roulette payouts are generally fixed (for example, a straight-up number pays 35 to 1), but the odds of winning change based on how many pockets exist on the wheel. That gap between payout and true probability is the house edge.
European roulette house edge (single zero)
- Total outcomes: 37
- On most common bets (including even-money and many inside bets), the house edge is typically about 2.70%.
American roulette house edge (double zero)
- Total outcomes: 38
- Because there are two zero pockets (0 and 00), the house edge increases to around 5.26% on standard bets.
Practical takeaway: Choosing European roulette instead of American roulette can nearly cut the house edge in half, which is a real, measurable advantage over time.
Wheel layout differences: not just the number of pockets
Both roulette types use the numbers 1–36, but the wheel sequence (the order of numbers around the wheel) is different. The layouts are designed to distribute high/low, odd/even, and red/black numbers around the wheel rather than grouping them together.
European roulette wheel sequence (standard)
0, 32, 15, 19, 4, 21, 2, 25, 17, 34, 6, 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16, 33, 1, 20, 14, 31, 9, 22, 18, 29, 7, 28, 12, 35, 3, 26American roulette wheel sequence (standard)
0, 28, 9, 26, 30, 11, 7, 20, 32, 17, 5, 22, 34, 15, 3, 24, 36, 13, 1, 00, 27, 10, 25, 29, 12, 8, 19, 31, 18, 6, 21, 33, 16, 4, 23, 35, 14, 2Why layout matters (realistically): The wheel sequence can matter to players who track outcomes and look for physical wheel bias. For most players using typical betting approaches, the dominant factor remains the zero count (single zero vs double zero) and any special rules that change the loss condition on zero.
Payouts and betting options: what stays the same
One reason roulette is so easy to compare is that most standard bets have the same payouts across European and American tables. What changes is your probability of winning due to 37 vs 38 pockets.
Common roulette bets and payouts
| Bet type | How it works | Typical payout | Win probability (European) | Win probability (American) |
|---|---|---|---|---|
| Straight up | One number | 35 to 1 | 1 / 37 | 1 / 38 |
| Split | Two adjacent numbers | 17 to 1 | 2 / 37 | 2 / 38 |
| Street | Three numbers in a row | 11 to 1 | 3 / 37 | 3 / 38 |
| Corner | Four-number square | 8 to 1 | 4 / 37 | 4 / 38 |
| Six line | Two streets (six numbers) | 5 to 1 | 6 / 37 | 6 / 38 |
| Dozen | 1–12, 13–24, 25–36 | 2 to 1 | 12 / 37 | 12 / 38 |
| Column | One of three columns | 2 to 1 | 12 / 37 | 12 / 38 |
| Even-money | Red/Black, Odd/Even, High/Low | 1 to 1 | 18 / 37 | 18 / 38 |
Benefit-driven insight: Since payouts are mostly the same, selecting the version with better probabilities (European roulette) is one of the simplest ways to improve your expected value without changing how you like to bet.
Rules that affect odds: French roulette (la partage and en prison)
Some European tables (often branded as French roulette) may offer special rules on even-money bets (Red/Black, Odd/Even, High/Low). These rules reduce the impact of the zero pocket when it appears.
La partage (typical effect)
If you place an even-money bet and the ball lands on 0, you lose only half your stake (the other half is returned).
En prison (typical effect)
If you place an even-money bet and the ball lands on 0, your stake is “imprisoned” for the next spin. If your bet wins on the next spin, you get your stake back (usually without profit). If it loses, you lose the stake.
How these rules change the house edge
On a single-zero wheel, either la partage or en prison effectively reduces the house edge on even-money bets to about 1.35% (half of the typical 2.7% edge), because the zero outcome is less punishing for those bets.
- If your priority is the best odds on simple bets like Red/Black, seek out European (single zero) roulette with la partage or en prison.
- If those rules are not offered, European roulette still typically beats American roulette due to the single zero.
Strategy impact: what changes between European vs American roulette
Roulette is a negative-expected-value game under standard rules, so no betting system can change the underlying house edge. The most effective “strategy” is choosing the best rule set and then playing in a way that supports your goals (entertainment, time on table, volatility preference).
1) Best table selection strategy: pick the lowest edge first
- Prefer single zero vs double zero whenever available.
- For even-money bettors, prioritize tables with la partage or en prison.
- Check the wheel type and any posted table rules before you buy in.
2) Match bet types to your experience goals
- Lower volatility: even-money bets (Red/Black, Odd/Even, High/Low) generally produce more frequent small wins, but still carry the house edge.
- Higher volatility: inside bets (like straight-up numbers) can deliver bigger payouts, but wins are less frequent.
- Balanced approach: dozens or columns can feel “chunky” (2 to 1 payout) with a moderate hit rate.
3) Bankroll and session structure (a practical edge you can control)
- Set a session budget and stick to it.
- Use consistent stake sizing if your goal is steadier swings.
- Consider a time limit to keep play intentional.
Positive outcome: While you can’t change the math of roulette, you can reliably choose conditions that make each spin more favorable and help you enjoy longer, more controlled sessions.

Regional legality and availability: what players should know
Roulette availability and rules are shaped by local gambling laws and operator policies, and these can differ widely by region.
Europe (general)
- Roulette is widely available in many European jurisdictions, typically under national regulatory frameworks.
- European (single-zero) roulette is common, and French rules may be offered at some venues, especially for even-money bets.
United States (general)
- Gambling law is often determined at the state level, and availability can vary significantly by location.
- American (double-zero) roulette is widely associated with US casino floors, though single-zero can also be found in some venues.
Online play (general)
- Online roulette legality (and online blackjack) depends on where the player is located and which operators are licensed to serve that jurisdiction.
- Game variants (European, American, French) are often clearly labeled, making it easier to choose based on your preferred odds and rules.
Practical tip: If you are comparing tables in any region, look first for the wheel type (single zero vs double zero) and then for rule notes like la partage or en prison.
Frequently searched questions (with clear answers)
Is European roulette always better than American roulette?
In terms of typical house edge, yes: European roulette usually offers better odds because it has a single zero (37 pockets) instead of a double zero (38 pockets). That difference is why the typical edge is about 2.7% vs around 5.26%.
Do payouts change between European and American roulette?
Most standard payouts are the same (for example, a straight-up number typically pays 35 to 1). The difference is your probability of hitting the bet due to the number of pockets on the wheel.
What is the biggest “hidden” advantage in European roulette?
Beyond the single-zero wheel, the biggest potential bonus is access to la partage or en prison rules on even-money bets, which can reduce the edge on those bets to about 1.35%.
Bottom line: the best value is usually single zero (and French rules are a bonus)
If your goal is to play smarter without changing the fun of roulette, the simplest upgrade is choosing European roulette over American roulette. The single zero vs double zero difference is the heart of the advantage, and the roulette house edge comparison shows exactly why it matters.
For players who enjoy even-money bets, adding la partage or en prison on a single-zero wheel can make your sessions feel meaningfully more efficient, with a lower built-in cost per spin.
