When you compare European roulette and American roulette, you’re really comparing two things that matter most to players: the wheel layout and the game math. Both versions look familiar at a glance, but the difference between a single zero wheel and a double zero wheel changes the house edge dramatically.
That’s good news if you like maximizing value: European roulette is typically the more player-friendly option because it has fewer pockets, a higher return to player (RTP), and (on some tables) special rules that further improve even-money bets.
Quick comparison: European roulette vs American roulette (layout, pockets, and house edge)
Here’s the clearest side-by-side snapshot. If you only remember one thing, remember that adding the double zero makes every bet slightly more expensive over time.
| Feature | European roulette | American roulette |
|---|---|---|
| Wheel pockets | 37 pockets (0 to 36) | 38 pockets (0, 00, and 1 to 36) |
| Zero pockets | Single zero (0) | Single zero (0) plus double zero (00) |
| Typical house edge | About 2.70% | About 5.26% |
| Typical RTP (theoretical) | About 97.30% | About 94.74% |
| Best for | Players seeking better long-run value | Players who enjoy the classic US layout and don’t mind higher cost |
Those percentages are based on standard rules and the fact that roulette pays fixed odds while the wheel probabilities change depending on how many pockets exist.
Wheel layout and number arrangement: what changes between European roulette and American roulette
Both games use the same set of numbers from 1 to 36, split into red and black, plus green pockets for the zero(s). The key differences are:
- European roulette wheel: includes one green pocket, the single zero (0).
- American roulette wheel: includes two green pockets, the single zero (0) and the double zero (00).
The number arrangement around the wheel (the order of numbers) also differs between European and American wheels. In practice, this does not change the mathematical edge by itself, but it can change the “feel” of the game and is part of why the two versions look distinct at a casino.
What does change the math is simply that extra pocket (00). Adding one additional losing outcome for many bets reduces the probability of winning without increasing the payout, which increases the house edge.
House edge and RTP explained (and why the double zero matters so much)
Roulette is a fixed-odds game. For example, a straight-up bet pays 35 to 1 in most casinos. That payout is the same whether the wheel has 37 pockets or 38 pockets, but your chance of hitting a specific number changes.
European roulette house edge: about 2.70%
On a European wheel, there are 37 equally likely outcomes. For a straight-up bet on one number:
- Win probability: 1 in 37
- Lose probability: 36 in 37
- Net win: +35 units (you receive 35 units profit; stake is typically returned as well)
- Net loss: -1 unit
The expected value works out to a loss of 1/37 of your stake per spin, which is about 2.70% of the amount bet.
American roulette house edge: about 5.26%
On an American wheel, there are 38 equally likely outcomes. For a straight-up bet:
- Win probability: 1 in 38
- Lose probability: 37 in 38
The expected loss becomes 2/38 of your stake per spin, which is about 5.26%. In other words, the double zero nearly doubles the cost of play over the long run compared with European roulette.
Rule variants in European roulette: en prison and la partage (lower house edge on even-money bets)
Many players love European roulette not only for the single zero, but also because some tables offer special rules that soften the impact of the zero on even-money bets (like red/black). These rules typically apply only to even-money wagers.
La partage
Under la partage, if you place an even-money bet (for example, red/black) and the ball lands on 0, you lose only half of your stake instead of the full amount.
This improves the house edge on even-money bets on a European wheel from about 2.70% to about 1.35%.
En prison
With en prison, when an even-money bet loses because the ball lands on 0, your bet is “imprisoned” for the next spin. On that next spin:
- If your bet wins, you recover your stake (typically without profit for that cycle).
- If it loses again, you lose your stake.
In terms of long-run value on even-money bets, en prison is generally similar to la partage, reducing the house edge on those bets to about 1.35% (under common interpretations).
Tip: If you’re choosing between two European roulette tables, a single zero wheel with la partage or en prison can be one of the most value-friendly roulette setups you’ll find for even-money play.
Common roulette bets and payouts (European roulette and American roulette)
The payout structure is broadly the same in both versions; what changes is the probability of winning because of the extra pocket on the American wheel. That’s why the house edge differs, even when payouts look identical.
| Bet type | Covers | Typical payout | How it feels in play |
|---|---|---|---|
| Straight up | 1 number | 35 to 1 | High variance, big hits, long droughts possible |
| Split | 2 adjacent numbers | 17 to 1 | Still swingy, slightly better hit rate than straight up |
| Street | 3 numbers in a row | 11 to 1 | A balance between payout and frequency |
| Corner | 4 numbers | 8 to 1 | Solid hit rate with meaningful payout |
| Six line | 6 numbers (two streets) | 5 to 1 | More frequent wins, smaller payout |
| Dozen | 12 numbers | 2 to 1 | Moderate swings; popular for structured betting |
| Column | 12 numbers | 2 to 1 | Similar to dozens, different coverage pattern |
| Even-money | Red/Black, Odd/Even, 1-18/19-36 | 1 to 1 | Smoother bankroll swings; best with la partage or en prison |
Important: In standard roulette, the built-in advantage comes from the zero pockets. When you bet on red, you’re effectively betting “red vs not red.” The green zero (and double zero in American roulette) sits outside the red/black set and creates the casino’s edge.
Why American roulette makes straight payouts and even-money odds worse
The payouts (like 35 to 1 for a straight up) generally don’t improve on the American wheel to compensate for the additional pocket. That means:
- For straight-up bets, you’re chasing the same payout with a lower hit probability on the double zero wheel.
- For even-money bets (red/black, odd/even), the extra green pocket increases how often you lose without changing the 1 to 1 payout.
Over time, the gap between about 2.70% (European) and about 5.26% (American) can be very noticeable, especially for players who make many spins in a session.
Bankroll-management tips that fit roulette (and help you enjoy longer sessions)
Roulette is a chance-based game with independent spins, so no betting pattern can remove the house edge. What you can do is manage volatility and improve the overall experience by controlling risk and session length.
1) Pick the best-value table first
- Prioritize European roulette (a single zero wheel) when possible.
- If available, choose rules like la partage or en prison for even-money bets.
- Avoid American roulette (the double zero wheel) if your goal is better long-run value.
2) Size bets so normal swings don’t knock you out
A practical approach is to keep a typical bet size small relative to your session bankroll. Many players choose a stake that allows for plenty of spins even during a cold streak, especially on outside bets.
3) Match bet types to your preferred volatility
- If you want smoother swings: focus on even-money, dozens, and columns.
- If you want bigger win spikes (and accept longer dry spells): use more straight up, splits, and other inside bets.
4) Set stop points before you start
Decide on a loss limit and a win target that feels satisfying. This doesn’t change the math, but it helps turn a roulette session into a planned entertainment budget rather than an open-ended chase.
5) Understand what strategies can and cannot do
Progression systems (increasing or decreasing bet sizes after wins or losses) can change the pattern of results, but they do not change the underlying probabilities. The most consistent “edge” you can gain in roulette is table selection: single zero beats double zero from a value standpoint.
Online vs land-based roulette tables: what to watch for
Both online and casino-floor roulette can be fun and engaging, but they differ in pace, transparency, and rule availability. Knowing what to look for helps you land on the best player experience.
Online roulette (RNG and live dealer)
- Game speed: Online RNG roulette can be fast, meaning more spins per hour (which can increase the impact of the house edge on your bankroll). Live dealer roulette is typically slower and more like a casino pace.
- Table variety: Online lobbies often make it easier to find European roulette and to compare whether a table is single zero or double zero.
- Rule clarity: The best online tables clearly list whether la partage or en prison applies, and to which bets.
Land-based roulette (casino floor)
- Atmosphere: The live setting, social energy, and ritual of the wheel are major benefits for many players.
- Limits: Minimum bets may be higher in some casinos, which can affect bankroll comfort.
- Wheel identification: It’s worth confirming whether the table is European roulette (look for one zero) or American roulette (look for 0 and 00).
Value-focused takeaway: Whether you play online or in person at a roulette casino, the most important checkbox is still the same: single zero if you want the lower house edge.
Choosing the right version: when European roulette is the smart pick
If you’re deciding purely on math, European roulette is typically the better choice because it has the lower house edge (about 2.70% vs about 5.26%). That difference can translate into longer playtime per bankroll and more value per spin.
European roulette becomes even more appealing when the table offers la partage or en prison, which can reduce the house edge on even-money bets to about 1.35%. For players who enjoy steadier pacing with red/black or odd/even, that rule upgrade is a real advantage.
American roulette remains popular for its classic presence in many US casinos and for players who simply enjoy the format. Just go in informed: the double zero is the reason the odds are less favorable.
FAQ: European roulette, American roulette, and house edge
Is European roulette always better than American roulette?
From a long-run value perspective, European roulette is usually better because the single zero wheel has a lower house edge. Preferences like atmosphere, availability, and table limits can still influence which game feels best for you.
Do betting systems overcome the house edge?
No betting system changes the underlying probabilities of roulette. What you can do is choose the most favorable version (typically single zero), select rules like la partage or en prison when available, and manage your bankroll to control risk.
Are payouts different between European and American roulette?
Most standard bets have the same published payouts in both games. The difference is that American roulette adds the double zero, reducing the chance of winning while payouts stay the same, which increases the house edge.
Bottom line: single zero wins on value
If your goal is to play roulette with the best typical odds, European roulette is the standout: the single zero wheel delivers a lower house edge (about 2.70%) than the double zero American wheel (about 5.26%). Add in player-friendly rules like la partage and en prison on even-money bets, and European roulette becomes a strong pick for longer sessions and better theoretical value.
Choose the right table, understand the bets, keep stakes comfortable, and you’ll get the best blend of excitement and efficiency from every spin.
