European and American roulette look similar at a glance: the same spinning wheel, the same bouncing ball, and the same familiar bets like red/black and straight-up numbers. But one small design change makes a big difference in your long-term results: European roulette uses a single zero (0), while American roulette adds an extra pocket, the double zero (00).
That extra 00 pocket is more than a cosmetic tweak. It increases the casino’s built-in advantage (the house edge) from about 2.70% on European roulette to about 5.26% on American roulette. Since the published payouts for most bets are nominally the same on both versions, the added 00 reduces your win probability and generally raises volatility. If you care about RTP (return to player), single-zero roulette is the objectively better default choice.
The Core Difference: Wheel Layout (37 vs 38 Pockets)
The defining difference is how many pockets are on the wheel:
- European roulette: numbers 1–36 plus a single 0=37 pockets
- American roulette: numbers 1–36 plus 0 and 00=38 pockets
Because roulette payouts were designed around a wheel that includes zeros, the more zero pockets there are, the more of the wheel is dedicated to outcomes that don’t pay most common bets (especially even-money and outside bets). That’s the direct reason the American wheel is less favorable for players.
House Edge Explained (With the Simple Math)
Roulette’s house edge comes from the mismatch between true odds and payout odds. A quick example is the straight-up bet (betting on a single number):
- Payout is typically 35 to 1 on both European and American roulette.
- But the chance of winning depends on how many pockets exist.
European roulette house edge
On a European wheel, there are 37 pockets. A straight-up bet wins 1 out of 37 times.
- True odds: 36 to 1 (because there are 36 losing outcomes for every winning outcome)
- Paid odds: 35 to 1
This gap produces the standard European roulette house edge of:
- 1 / 37 ≈ 2.70%
American roulette house edge
On an American wheel, there are 38 pockets. A straight-up bet wins 1 out of 38 times.
- True odds: 37 to 1
- Paid odds: 35 to 1
The standard American roulette house edge becomes:
- 2 / 38 ≈ 5.26%
Notice what happened: the wheel added just one more pocket, but the house edge nearly doubled.
Quick Comparison Table: European vs American Roulette
| Feature | European Roulette | American Roulette |
|---|---|---|
| Wheel pockets | 37 (1–36 + 0) | 38 (1–36 + 0 + 00) |
| Standard house edge | About 2.70% | About 5.26% |
| Common even-money rules | May offer la partage or en prison | Usually standard rules |
| Even-money effective edge (with favorable rules) | About 1.35% on even-money bets (when la partage applies) | Typically remains about 5.26% |
| Typical regional availability | Common in Europe and widely available online | Common in many U.S. land-based casinos |
| Payouts shown on the felt | Generally the same as American | Generally the same as European |
Payouts Are Similar, But Your Win Probability Isn’t
A common point of confusion is that many payouts look identical on both versions. For example:
- Straight-up: 35 to 1
- Split: 17 to 1
- Street: 11 to 1
- Corner: 8 to 1
- Dozen / Column: 2 to 1
- Red/Black, Odd/Even, High/Low: 1 to 1
However, the American wheel’s extra 00 means each bet hits slightly less often. Over many spins, that small reduction in hit rate adds up to a meaningfully lower RTP and a steeper expected loss per unit wagered.
In practical terms: if you’re playing roulette primarily for entertainment, both versions can be fun; some players instead choose to play blackjack. If you’re choosing based on value, the single-zero wheel is the clear winner.
European Rule Variants That Improve Your Odds: La Partage and En Prison
One of the biggest “hidden advantages” of many European roulette tables is the availability of special rules on even-money bets (red/black, odd/even, high/low). These rules reduce the sting of landing on zero.
La partage (often the most player-friendly)
Under la partage, when you place an even-money bet and the ball lands on 0, you lose only half your stake (the other half is returned).
This can reduce the house edge on even-money bets in European roulette to about:
- 1.35% (approximately half of 2.70%)
That’s a meaningful improvement for players who prefer steadier, lower-volatility betting styles like red/black or high/low.
En prison (similar effect, slightly different mechanism)
With en prison, when an even-money bet loses to 0, your bet is “imprisoned” for the next spin instead of being lost immediately. If your even-money bet wins on the next spin, you get your stake back (typically without additional profit). If it loses again, you lose the stake.
In many standard implementations, en prison offers an effective edge on even-money bets that is very close to 1.35%, similar to la partage. The exact player impact can vary by table rules, so it’s worth confirming how the casino applies it.
Important detail: These rules typically apply only to even-money bets
It’s a great bonus if you like outside bets, but it doesn’t generally improve the odds for dozens, columns, or inside bets like straight-ups and splits.
Wheel and Table Layout Differences (What You’ll Notice as a Player)
Beyond the presence of 00, you’ll notice some physical and visual differences that affect how the game feels—especially if you switch between land-based tables, live dealer games, and RNG (digital) roulette.
Wheel numbering pattern
European and American wheels use different sequences for number placement around the wheel. The exact order isn’t something you need to memorize to play well, but it’s part of why the wheels look different and why some players have strong preferences.
Table felt: the 00 changes the betting grid
- European felt has a single zero at the top of the number grid.
- American felt includes both 0 and 00, usually placed side by side at the top.
That one extra box subtly affects player behavior: newer players sometimes treat 00 like “just another number,” but from an RTP perspective, it’s an additional house-favoring outcome you’re up against.
Variance and Volatility: Why American Roulette Can Feel Swingier
Roulette is a game of independent spins, so short-term results can vary widely in any version. Still, the American wheel’s higher house edge typically means:
- Lower win probability for the same bet types
- Higher expected loss for the same wagering volume
- Often more pronounced downswings over comparable sessions, especially for players making lots of spins
Even when the payout table is identical, the extra 00 creates a slightly harsher environment for bankroll longevity. If your goal is to stretch playtime, enjoy a steadier ride, or play closer to optimal RTP, European roulette (especially with la partage or en prison) is the more supportive choice.
Availability: Where You’re Most Likely to Find Each Version
In Europe
Single-zero roulette is common across European casinos. You’re also more likely to see European-friendly rule variants like la partage and en prison in many venues, particularly at traditional tables.
In the United States
Many U.S. land-based casinos traditionally offer double-zero (American) roulette as the default. That said, some venues may offer single-zero roulette tables as a premium option, in high-limit areas, or as special-feature tables.
Online casinos (RNG and live dealer)
Online platforms frequently offer multiple roulette versions side by side, including:
- European (single-zero) roulette
- American (double-zero) roulette
- Sometimes French roulette (often European wheel with la partage/en prison)
This is a big win for RTP-conscious players: you can usually choose the more favorable wheel and rules without needing to be in a specific region.
Live Dealer vs RNG Roulette: What Changes (and What Doesn’t)
Whether you play live dealer roulette (real wheel streamed from a studio) or RNG roulette (digital outcomes generated by software), the most important value drivers stay the same:
- Single zero vs double zero
- Whether favorable rules apply on even-money bets
- Table limits and your bet sizing
Live dealer roulette: realism and pace
Live games often feel more immersive: you can see the wheel, the ball, and the outcome process. The pace can also be more measured than rapid-fire RNG, which can be a benefit for bankroll control because it reduces the number of decisions (and wagers) per hour.
RNG roulette: speed and flexibility
RNG roulette can be faster and more flexible, often offering quick betting, auto-play features, and a wide range of limits. The trade-off is that higher spin volume can increase short-term volatility simply because you’re making more bets in the same time window.
In both formats, choosing a single-zero game is the simplest way to keep more value on your side.
Betting Limits and Table Conditions: Small Details That Matter
Two roulette tables can both be “European roulette” and still play quite differently depending on limits and conditions. If you want a smoother experience and stronger bankroll management, it helps to check:
- Minimum bet: Lower minimums let you ride out variance longer.
- Maximum bet: Higher maximums help if you enjoy larger swings, but they don’t improve RTP by themselves.
- Maximum on specific bets: Some tables cap straight-ups or outside bets differently.
- Rule set: Whether la partage or en prison is offered (and how it is applied).
From a player-benefit perspective, an ideal setup for many recreational players is a single-zero wheel with la partage on even-money bets and a minimum bet that fits comfortably within your bankroll.
Practical Takeaways: How to Choose the Best Roulette Game
If you want the best blend of enjoyment, value, and longevity, these guidelines keep your decision simple and effective.
1) Prefer single-zero (European) roulette whenever possible
This is the biggest, clearest edge you can give yourself as a player. The difference between about 2.70% and about 5.26% is substantial over time.
2) Look for French-style rules on even-money bets
If you enjoy red/black, odd/even, or high/low, seek tables that offer:
- La partage (often displayed on the table signage or game info)
- En prison (confirm the exact handling rules)
These rules can improve the effective value of even-money bets by reducing the cost of the zero outcome.
3) Confirm the wheel type before you sit down (or click “play”)
In busy casino environments, it’s easy to miss whether a table is European or American. The simplest check is the felt:
- If you see only 0, you’re on a single-zero layout.
- If you see 0 and 00, it’s the American layout.
4) Size your bets to handle volatility
Roulette variance is real, even with outside bets. A practical, entertainment-first approach is to keep each wager small relative to your bankroll so that natural swings don’t end your session early.
- Many players prefer betting units that allow for at least 100 spins of play, depending on pace and bet type.
- Inside bets (like straight-ups) can be higher variance; outside bets tend to be steadier but still swing.
5) Keep expectations realistic and focus on fun plus value
Roulette is designed with a house edge, so no table choice turns it into a guaranteed-profit game. What smart table selection does do is improve your RTP, stretch your bankroll, and support longer, more satisfying sessions—especially when you consistently choose single-zero games.
European vs American Roulette FAQ
Is European roulette always better than American roulette?
From an RTP perspective, yes: the standard European house edge is about 2.70% versus about 5.26% on standard American roulette. If you also find la partage or en prison on even-money bets, European-style tables can be even more favorable for those bet types.
Do payouts differ between European and American roulette?
Most standard payouts are the same, which is exactly why the American wheel’s extra 00 matters so much: you’re generally paid the same but win slightly less often.
What’s the best roulette bet if I want lower volatility?
Even-money outside bets (like red/black or high/low) tend to have lower volatility than inside bets. They don’t change the house edge by themselves, but they can create a smoother session experience. They become especially attractive on single-zero tables with la partage or en prison.
Is French roulette the same as European roulette?
They are closely related. French roulette typically uses the single-zero wheel and is commonly associated with favorable rules like la partage and en prison on even-money bets. European roulette often refers broadly to the single-zero version; specific rule availability depends on the table.
Bottom Line: Choose Single-Zero, Confirm Favorable Rules, and Play Smart
If you want the best value in roulette without changing how you enjoy the game, focus on three high-impact decisions:
- Choose European (single-zero) roulette over American (double-zero) whenever you can.
- Prioritize tables with la partage or en prison if you like even-money bets.
- Use bankroll-aware bet sizing to handle normal variance and keep your sessions enjoyable.
With those simple steps, you’ll keep more RTP on your side, reduce the cost of play over time, and give yourself the best chance to enjoy roulette the way it’s meant to be enjoyed: exciting, social, and packed with suspense—without paying extra for the same thrill.
