Roulette looks deceptively similar from one casino (or app) to the next: the same wheel, the same green pocket, the same iconic 35:1 payout for a straight-up number. But one small detail changes everything for your long-term value as a player: how many green pockets the wheel has.
European (single-zero) roulette has 37 pockets (numbers 1–36 plus a single 0).American (double-zero) roulette has 38 pockets (1–36 plus 0 and 00). That extra 00 pocket doesn’t change the posted payouts, but it does change the probabilities of winning, which raises the house edge from about 2.70% on European wheels to about 5.26% on American wheels.
If you care about stretching your bankroll, getting a higher return-to-player (RTP), and giving your bets the best possible mathematical footing, this single difference is the reason most informed players actively seek out single-zero roulette. And if you can find French roulette with player-friendly rules like la partage or en prison, you can often do even better on even-money bets.
At a Glance: European vs American Roulette (Key Differences)
| Feature | European Roulette | American Roulette |
|---|---|---|
| Number of pockets | 37 | 38 |
| Green pockets | 0 | 0 and 00 |
| House edge (most bets) | ~ 2.70% | ~ 5.26% |
| RTP (theoretical) | ~ 97.30% | ~ 94.74% |
| Straight-up payout (single number) | 35:1 | 35:1 |
| Common “best for value” tables | Single-zero, especially French rules | Less favorable; avoid if single-zero is available |
| Rules that can reduce edge on even-money bets | La partage and en prison (often in French roulette) | Uncommon |
Why the Extra 00 Matters: Probabilities Change, Payouts Don’t
Roulette is built on a simple idea: each pocket has an equal chance of landing on a fair wheel, but the payouts are set so that the casino keeps a built-in advantage over time.
The most important point to remember is this:
- Payouts are usually the same on European and American roulette (for example, a straight-up number typically pays 35:1).
- Your chance of winning is not the same, because the number of pockets is different.
That mismatch between payout and probability is what creates the house edge. When you add the 00, you reduce the chance of hitting your bet without improving your payout, which lowers your expected return.
European Roulette: 37 Pockets and a ~ 2.70% House Edge
European roulette uses numbers 1–36 plus a single green 0, for a total of 37 outcomes.
Example: Straight-Up Bet (Single Number)
- Win probability on European roulette: 1 / 37 (about 2.70%)
- Payout: 35:1 (you win 35 units, plus you typically get your 1-unit stake back)
The house edge is ~ 2.70% on most standard bets because the wheel has 37 pockets, but the straight-up payout is based on 35 rather than 36 to reflect a fair game.
In terms of theoretical RTP, European roulette returns about 97.30% to players over a very large number of spins (with normal rules and standard bets).
American Roulette: 38 Pockets and a ~ 5.26% House Edge
American roulette adds a second green pocket, 00, making 38 total outcomes.
Example: Straight-Up Bet (Single Number)
- Win probability on American roulette: 1 / 38 (about 2.63%)
- Payout: 35:1 (same posted payout as European)
Because your chance of winning drops but your payout stays the same, the expected value worsens. The house edge rises to ~ 5.26%, and the theoretical RTP becomes about 94.74%.
That difference can feel small in a single session, but it becomes meaningful over time because roulette is a high-volume game: spins happen quickly, and small percentage differences add up faster than many players expect.
House Edge vs RTP: The Practical Way to Think About Value
Two terms come up constantly in roulette discussions: house edge and RTP. They are two sides of the same coin.
- House edge is the casino’s built-in advantage (a long-run average).
- RTP (return to player) is what remains: RTP = 100% − house edge.
So if a roulette table has a house edge of about 2.70%, the RTP is about 97.30%. If the house edge is about 5.26%, the RTP is about 94.74%.
From a player’s perspective, higher RTP is a clear benefit: it means your money tends to last longer, and you’re giving yourself a more favorable baseline for any style of play, from low-volatility outside bets to high-variance straight-ups.
Common Roulette Bets: Same Payouts, Different Odds
Roulette bets fall into two big categories:
- Inside bets (placed on specific numbers or small number groups): higher payouts, lower win rate.
- Outside bets (placed on broader outcomes like red/black): lower payouts, higher win rate.
On both European and American roulette, the payouts are typically identical. The difference is that the probability of winning is slightly better on the 37-pocket wheel.
Typical Payouts (Most Standard Tables)
- Straight-up (1 number): 35:1
- Split (2 numbers): 17:1
- Street (3 numbers): 11:1
- Corner (4 numbers): 8:1
- Six line (6 numbers): 5:1
- Dozen (12 numbers): 2:1
- Column (12 numbers): 2:1
- Even-money bets (18 numbers): 1:1 (red/black, odd/even, high/low)
The key takeaway is simple: if you’re receiving the same payout for an event that is less likely (as in American roulette), you’re accepting a worse deal.
French Roulette: The European Variant That Can Improve Even-Money Bets
French roulette is typically played on a single-zero wheel, which already starts you at the European baseline of about 2.70% house edge. Where it can shine is in common table rules that reduce the casino advantage on even-money outside bets.
La Partage
La partage (French for “the sharing”) is a rule often applied to even-money bets (red/black, odd/even, high/low) when the ball lands on 0.
- If you place an even-money bet and the ball lands on 0, you lose only half your stake (instead of losing the full amount).
This improves the value of even-money bets and reduces the effective house edge on those bets from ~2.70% to ~1.35% on a single-zero wheel.
En Prison
En prison (“in prison”) is another rule sometimes offered on French roulette for even-money bets when the result is 0.
- Your even-money bet is “imprisoned” for the next spin instead of losing immediately.
- If your bet wins on the next spin, you typically get your stake back (without profit).
- If it loses, you lose the stake.
- If 0 appears again, house rules vary by casino, but commonly the bet remains imprisoned for another spin.
Under standard handling, en prison produces the same effective house edge as la partage on even-money bets: roughly 1.35%.
Benefit-driven takeaway: If you prefer outside bets for steadier pacing, French roulette rules can be one of the most player-friendly upgrades you’ll find in traditional roulette formats.
What About Strategies? Why None Can Remove the Built-In Disadvantage
It’s completely natural to look for a system that “beats” roulette: progressions, patterns, and wheel-tracking theories have been discussed for generations. But from a mathematical standpoint, standard roulette is designed so that the house edge is built into the game structure.
- Changing bet sizes (for example, using a progression) can change variance and how your session feels.
- It does not change the underlying probabilities of the wheel.
- As a result, it does not eliminate the house edge.
The most reliable “strategy” in roulette is simply table selection: choosing the version of the game with the best RTP and the rules that give you the most value for the bets you like to make.
Choosing the Best Roulette Table: A Practical Checklist
If you want the most value out of roulette without overcomplicating your play, focus on a few high-impact checks before you place your first chip.
1) Prefer Single-Zero Wheels
- Choose European roulette (0) over American roulette (0, 00) whenever you can.
- This alone moves you from ~5.26% house edge to ~2.70% on typical bets.
2) Look for French Rules if You Play Outside Bets
- If you like red/black, odd/even, or high/low, seek tables with la partage or en prison.
- These can reduce the effective house edge on those bets to ~1.35%.
3) Confirm the Rule Applies to Your Bet
Not every “French roulette” presentation guarantees a specific rule applies to every even-money bet, and casinos can differ in how they implement edge-reducing rules. If the game information (or table placard) clarifies the rule, it’s worth checking before you commit to a style of play.
4) Match Table Limits to Your Bankroll
- Outside-bet players often benefit from lower minimums to absorb normal streaks.
- Inside-bet players may want enough headroom to handle variance without feeling forced to chase.
5) Keep the Game Simple and Consistent
Consistency makes roulette more enjoyable and easier to manage. Whether you prefer a flat-bet approach (same stake each spin) or occasional increases, the value gains mostly come from the wheel type and the rules, not from constantly switching bet structures.
Online Roulette: Live Dealer vs RNG (and How the Choice Affects Your Experience)
online roulette games generally come in two formats:
Live Dealer Roulette
- Uses a real physical wheel streamed from a studio or casino environment.
- Often includes table limits and rules similar to land-based roulette.
- Can feel more immersive: real dealers, real wheel spins, and a more social pace.
RNG Roulette
- Outcomes are generated by a random number generator rather than a physical wheel.
- Typically faster-paced, with more control over speed and sometimes more table options.
- Can be a convenient way to focus on the math (wheel type, rules, and RTP) without waiting for dealer cycles.
Value tip: In either format, the biggest win for your long-term value is still the same: choose single-zero (and preferably French rules for even-money bets) when available.
European vs American Roulette: Concrete Odds Examples
Here are a few quick comparisons that show how the extra pocket changes your winning chances.
Straight-Up (One Number)
- European: 1 / 37≈2.70%
- American: 1 / 38≈2.63%
Red or Black (Even-Money)
There are 18 red numbers and 18 black numbers on both wheels. The difference is in the green pockets.
- European (one green pocket): win probability ≈18 / 37≈48.65%
- American (two green pockets): win probability ≈18 / 38≈47.37%
That roughly 1.28 percentage point difference might not look dramatic, but it directly impacts how often you win those “coin-flip style” bets and how frequently the green pocket disrupts outside-bet momentum.
The Biggest Player Benefit: Your Bankroll Typically Lasts Longer on Single-Zero
Because the house edge is lower on European roulette, your expected losses per unit wagered are smaller in the long run. That often translates into a more enjoyable session: more spins, more opportunities to hit, and a better balance between risk and entertainment value.
This is a major reason many experienced roulette players gravitate toward single-zero and French tables. It’s not about “guaranteed wins” (roulette can’t offer that), but about getting a better deal on the same style of bets.
Frequently Asked Questions
Is European roulette always better than American roulette?
From a mathematical value standpoint, yes in standard form: European roulette’s ~2.70% house edge is more favorable than American roulette’s ~5.26%. If both are available, single-zero is typically the better choice for RTP.
Do payouts change between European and American roulette?
Usually no. The posted payouts (like 35:1 for a straight-up bet) are typically the same. The difference comes from the number of pockets, which changes the odds.
Is French roulette different from European roulette?
French roulette typically uses the same single-zero wheel as European roulette, but it may include additional rules such as la partage or en prison that can improve the value of even-money bets.
Can la partage or en prison eliminate the house edge?
No. They can reduce the effective house edge on even-money bets to about 1.35% on a single-zero wheel, but the game still has a built-in disadvantage for players in the long run.
Is live dealer roulette fairer than RNG roulette?
They are different experiences. Fairness depends on proper operation and oversight, but from a value perspective your best move is still to pick the most favorable wheel type and rules (single-zero, and French rules where available), whether the game is live dealer or RNG.
Bottom Line: The Best Choice for Most Players
If you want the most player-friendly version of roulette, prioritize your selection in this order:
- French roulette with la partage or en prison (especially if you like even-money bets)
- European roulette (single-zero)
- American roulette only if single-zero options are unavailable
Roulette will always have built-in house advantage, and no betting system can remove it. But choosing the right wheel and rules is a genuinely powerful upgrade: it keeps more of your bankroll in play, increases your theoretical RTP, and gives you a better-value game without changing what makes roulette fun in the first place.
