If you’ve ever wondered why two roulette tables can look nearly identical yet produce very different long-term results, the answer is simple: the wheel layout. The key difference in European vs American roulette is the presence of an extra green pocket on the American wheel. That single change meaningfully impacts player odds, expected returns, and how long your bankroll can last.
This guide breaks down the wheel layouts, the double zero house edge, how en prison vs La Partage can improve even-money bets, and what to look for if you want the best roulette to play online.
European vs American roulette at a glance
Both versions share the same core experience: you place chips on a betting layout, the dealer spins the wheel, and payouts follow standard roulette rules. What changes is the math behind the scenes.
| Feature | European (and French) Roulette | American Roulette |
|---|---|---|
| Total pockets | 37 (0 to 36) | 38 (0, 00, and 1 to 36) |
| Green pockets | Single zero (0) | Zero (0) anddouble zero (00) |
| Typical house edge | ~2.70% | ~5.26% |
| Even-money improvement rules | Sometimes: La Partage or en prison (often on French roulette) | Typically none |
| Core bet types and payouts | Same as American roulette | Same as European roulette |
That “one extra pocket” (the 00) is why players often search for terms like European vs American roulette and double zero house edge. It’s also why many strategy discussions start with a simple recommendation: when given the choice, prefer European or French roulette.
Wheel layout: 37 vs 38 pockets (and why it matters)
Roulette is built on fixed payouts. For example, a straight-up bet pays 35 to 1 whether you’re playing European or American roulette. Because the payout is the same, the version with more losing outcomes for the same winning payout will be worse for the player.
European roulette wheel
- Numbers: 1 to 36
- One green pocket: 0
- Total outcomes: 37
American roulette wheel
- Numbers: 1 to 36
- Two green pockets: 0 and 00
- Total outcomes: 38
The practical takeaway: the American wheel gives you one more way to lose on most bets, while keeping payouts unchanged. Over time, that gap shows up in your results.
Double zero house edge explained (with exact figures)
The house edge is the casino’s long-run advantage, expressed as a percentage of each bet. It does not mean you lose that amount every session, but it does describe the expected cost of playing over many spins.
European roulette house edge: about 2.70%
European roulette has 37 pockets. With standard payouts, the built-in edge is:
- House edge: 1 / 37 ≈2.70%
American roulette house edge: about 5.26%
American roulette has 38 pockets because of the 00. With standard payouts, the edge becomes:
- House edge: 2 / 38 ≈5.26%
This is why the phrase double zero house edge is so important: that extra 00 nearly doubles the casino advantage compared to European roulette.
Roulette odds and payouts: same payouts, different returns
A common surprise for newer players is that the payouts don’t change between European and American roulette for the standard bets. What changes is the probability of winning because there are 37 outcomes vs 38.
Below is a quick reference for popular bets, including the standard payout and the win probability for each wheel type.
| Bet type | Covers | Standard payout | Win chance (European, 37) | Win chance (American, 38) |
|---|---|---|---|---|
| Straight up | 1 number | 35 to 1 | 1/37 ≈ 2.70% | 1/38 ≈ 2.63% |
| Split | 2 numbers | 17 to 1 | 2/37 ≈ 5.41% | 2/38 ≈ 5.26% |
| Street | 3 numbers | 11 to 1 | 3/37 ≈ 8.11% | 3/38 ≈ 7.89% |
| Corner | 4 numbers | 8 to 1 | 4/37 ≈ 10.81% | 4/38 ≈ 10.53% |
| Dozen / Column | 12 numbers | 2 to 1 | 12/37 ≈ 32.43% | 12/38 ≈ 31.58% |
| Even-money (Red/Black, Odd/Even, 1–18/19–36) | 18 numbers | 1 to 1 | 18/37 ≈ 48.65% | 18/38 ≈ 47.37% |
Even though the difference in win percentage looks small per spin, it compounds with volume. If you play hundreds of spins, that extra 00 can have a very real impact on how long you get to enjoy the game.
French roulette rules: en prison vs La Partage (and how they help)
If you want better value from roulette, this is one of the most player-friendly features you can find.French roulette typically uses the same single-zero wheel as European roulette (37 pockets), but some tables add special rules for even-money bets (like Red/Black or Odd/Even).
The two famous rules are La Partage and en prison. They are similar in benefit, but not identical in how they play.
La Partage (share the bet)
When you place an even-money bet and the ball lands on 0, you get half your stake back and lose the other half.
- Example: You bet 10 on Black. If 0 hits, you lose 5 and get 5 returned.
En prison (in prison)
When you place an even-money bet and 0 appears, your bet is “imprisoned” for the next spin instead of being lost immediately.
- If your bet wins on the next spin, you typically get your stake back (effectively a push on the original bet).
- If it loses on the next spin, you lose the stake.
Why these rules are a big deal: effective edge can drop to ~1.35%
On a standard European single-zero wheel, the house edge is about 2.70%. With La Partage or en prison applied to even-money bets, the effective house edge on those even-money bets can fall to roughly 1.35%, because the 0 outcome becomes less punishing.
Important nuance: this benefit applies to even-money bets only. Straight-up, split, street, and other inside bets generally keep the standard single-zero edge.
European vs American roulette: a practical expected-value example
Sometimes the easiest way to feel the difference is to translate the percentages into a simple “expected cost” illustration. While real sessions vary, the math provides a clear baseline.
Example: 100 in total wagers
- European roulette (standard rules): expected cost ≈2.70 per 100 wagered.
- American roulette: expected cost ≈5.26 per 100 wagered.
- European/French roulette with La Partage or en prison on even-money bets: expected cost on those bets ≈1.35 per 100 wagered.
Look at what’s happening: the American wheel’s extra 00 increases the long-run cost of play, while French-style even-money rules can reduce it. If your goal is to maximize entertainment time per deposit, those differences matter.
Best roulette to play online: what to choose (and what to check)
If you’re choosing between roulette games online, you can turn the math into a simple checklist. The best choice is usually the one that gives you the most favorable rules without changing the classic roulette payouts you already know.
1) Prefer European or French roulette (single zero)
Start by selecting games labeled European roulette or French roulette. The key feature to confirm is a wheel with only one green 0 (37 pockets total).
2) Look for La Partage or en prison if you like even-money bets
If your style is built around Red/Black, Odd/Even, or High/Low bets, prioritize a French roulette table that clearly states La Partage or en prison. This is one of the clearest, most rule-based ways to improve your effective return on those bet types.
3) Use demo mode to build confidence and rhythm
play blackjack online and many online platforms offer a free-play or demo mode for roulette variants. Demo mode won’t change the math, but it can help you:
- Learn bet placements quickly (inside vs outside bets).
- Practice consistent staking (important for bankroll control).
- Get comfortable with table speed and interface.
4) Confirm table limits match your bankroll
A “great” roulette game can still feel uncomfortable if minimum bets are too high. A good fit lets you play at a pace that supports your entertainment goals and reduces the chance of busting quickly from normal variance.
Bankroll management tips that fit roulette (without overpromising)
Roulette is a negative expected-value game in the long run, so the biggest win you can create is often better control over session length and volatility. Smart bankroll habits can make your play feel smoother and more intentional.
Set a session budget and treat it as spent
- Decide your session bankroll upfront (for example, 100).
- Once set, avoid topping up mid-session to “chase” outcomes.
Use flat betting for steadier swings
Flat betting means keeping your stake consistent (for example, 1 per spin). This doesn’t change the house edge, but it can help you avoid big drawdowns caused by aggressive bet increases.
Choose bet types that match your variance preference
- Inside bets (like straight-up) offer bigger payouts but lower hit frequency.
- Outside bets (like Red/Black) hit more often, which many players find more enjoyable for longer sessions.
Consider a simple stop-win and stop-loss
Because short-term variance can swing either way, some players find it helpful to predefine:
- A stop-loss (when you’ll end the session to protect your budget).
- A stop-win (when you’ll lock in a profit and end on a high note).
Success stories in practice: what improves when players switch wheels
You don’t need a complicated system to improve your roulette experience. In practice, the most reliable “upgrade” is simply choosing a more favorable wheel and ruleset.
- Longer play time per bankroll: Players who move from American roulette to European roulette often find they can play more spins with the same budget, because the expected cost per unit wagered is lower.
- More value for outside-bet players: Players who prefer Red/Black, Odd/Even, or High/Low can get a meaningful boost when they find French roulette with La Partage or en prison, where the effective edge on those bets can drop to roughly 1.35%.
- Clearer decision-making: When your “strategy” starts with picking the right game (single zero, favorable even-money rules), your choices become simpler and more consistent.
These aren’t guarantees of winning sessions, but they are realistic, math-based improvements that can make roulette feel more rewarding as a form of entertainment.
