If you’re searching for European roulette vs American roulette, you’re already doing the smartest thing a roulette player can do: comparing odds before you play roulette. Roulette looks similar everywhere (same felt, same chips, same iconic spin), but one small detail changes everything for your long-term results: single zero vs double zero.
This guide breaks down the core differences that matter most to your bankroll and your playing experience: wheel layout, payout structure, roulette house edge, RTP, and strategy implications (including the player-friendly en prison rule and la partage).

The core difference: single zero vs double zero
The most important distinction between European and American roulette is the number of green zero pockets on the wheel:
- European roulette has one zero (0) and 37 pockets total (numbers 1–36 plus 0).
- American roulette has two zeros (0 and 00) and 38 pockets total (numbers 1–36 plus 0 and 00).
That extra pocket in American roulette doesn’t change the payout table, but it does change the math behind every bet you place. Over time, that difference shows up as a meaningfully higher cost of play.
European roulette vs American roulette: house edge and RTP explained
Roulette is designed so that the payouts are slightly lower than “true odds.” That difference is the casino advantage, also called the roulette house edge. Here are the headline numbers most players care about:
- European roulette house edge: about 2.70%
- American roulette house edge: about 5.26%
Those house edges correspond to the Return to Player (RTP):
- European roulette RTP: about 97.30%
- American roulette RTP: about 94.74%
In practical terms, a lower house edge means your money tends to last longer, and you get more spins for the same budget. If your goal is the best roulette to play from an odds perspective, European roulette is usually the clear favorite.
Why the house edge differs (with simple math)
The key is that the payouts are effectively built around a 36-to-1 wheel for many bets, but the wheel has either 37 or 38 pockets.
Example: A straight-up bet (one number) typically pays 35:1. If you stake 1 unit and win, you receive 35 units profit (and you also get your 1 unit stake back in most standard rules). The true odds of hitting a single number are:
- European: 1 / 37
- American: 1 / 38
Because the payout is the same but the chance of winning is lower on the American wheel, the American version yields a higher house edge.
Payouts: the surprising part (they’re basically the same)
One reason many players don’t notice the difference right away is that the payouts are the same on both wheels for the standard bets.
Common examples include:
- 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 / Column: 2:1
- Even-money bets (Red/Black, Odd/Even, High/Low): 1:1
So if payouts don’t change, what does? The wheel’s composition. That extra 00 in American roulette increases the number of losing outcomes for every bet (especially for outside bets), while leaving the winnings unchanged.
Wheel layout differences: European vs American roulette
Beyond the number of pockets, there’s also the arrangement of numbers around the wheel. Both wheels use non-sequential ordering designed for balance and randomness, but the American wheel includes both 0 and 00. The presence of 00 is the main layout detail that affects odds.
What this means for players:
- In European roulette, there’s only one green “trap” number (0) that causes many bets to lose.
- In American roulette, there are two green “trap” numbers (0 and 00), which increases volatility and the casino’s long-run advantage.
If you’re comparing single zero vs double zero, the wheel layout is the visible proof of the math: more green pockets generally means a higher house edge.

European variants with better odds: en prison and la partage
When players talk about the best roulette to play, they often mean not just “European roulette” in general, but European roulette with additional rules that improve outcomes on even-money bets.
Two famous rules are:
1) En prison rule
The en prison rule applies to even-money bets (like Red/Black). If the ball lands on 0, your bet isn’t immediately lost. Instead, your stake is “imprisoned” for the next spin:
- If your bet wins on the next spin, you get your stake back (typically without additional profit).
- If your bet loses on the next spin, you lose your stake.
- If 0 hits again, many tables keep the bet imprisoned (exact handling can vary by house rules).
This rule reduces the effective cost of playing even-money bets compared to standard European rules without it.
2) La partage
La partage (often written as “la partage”) also applies to even-money bets. If the ball lands on 0:
- You lose only half of your even-money stake.
For even-money bets, both la partage and en prison commonly reduce the effective house edge from about 2.70% to about 1.35% (because the zero outcome is partially refunded or deferred instead of being a full loss).
If you enjoy outside bets for steadier swings, seeking a table with one of these rules can be a major upgrade in value.
Strategy implications: how the wheel changes the way you should play
Roulette is a negative-expectation game in the long run because of the house edge, so no betting system can guarantee profits. However, choosing the better-odds variant is a powerful way to improve your overall experience.
1) Bankroll longevity: more spins, more entertainment
The lower roulette house edge in European roulette generally means:
- Your bankroll tends to last longer for the same bet sizing.
- You may be able to play longer sessions with the same budget.
- Short-term swings still happen, but the “cost per spin” is lower.
Many players find that European roulette simply feels more forgiving over a long evening, especially when sticking to outside bets.
2) Outside bets get a bigger boost from player-friendly rules
If you mainly play Red/Black, Odd/Even, or High/Low, European roulette with en prison rule or la partage can be especially attractive. Those rules don’t typically change the payouts, but they improve what happens on the zero, which is exactly what drives the house advantage on outside bets.
3) Inside bets: edge difference still matters
Even if you love straight-up numbers and other inside bets, the single zero vs double zero difference still matters because:
- The payouts remain the same (for example, 35:1 for a straight bet).
- The American wheel simply has one more losing pocket.
So while the game feels identical spin-to-spin, the European wheel offers better long-term value.
Which roulette is best to play for odds?
If your goal is to maximize RTP and minimize the house edge, a simple ranking helps:
- European roulette with la partage or en prison (especially if you play even-money bets)
- Standard European roulette (single zero)
- American roulette (double zero)
That ranking is why searchers comparing European roulette vs American roulette so often land on the same conclusion: if you have a choice, the European wheel is typically the better pick.
Practical tips to spot the better game fast
In a busy casino environment (or while browsing game lobbies), you can quickly identify what you’re getting by checking for these details:
- Look at the wheel: do you see 00? If yes, it’s American roulette.
- Check the table layout: an American layout typically includes a separate 00 box.
- Review the rules panel: look specifically for the terms en prison rule or la partage.
- Confirm the payout for a straight bet: it should be 35:1. (If you ever see a lower payout, that’s a different and usually less favorable ruleset.)
These quick checks help ensure you’re truly getting the odds you expect when comparing single zero vs double zero.
How much difference does the house edge make over time?
The house edge is a long-run average, not a prediction of what happens in a single session. You can win or lose in the short term on either wheel. Still, the house edge is a useful compass for choosing value.
Consider a simplified way to think about it:
- A 2.70% house edge means the average cost is about 2.70 units per 100 units wagered over the long run.
- A 5.26% house edge means the average cost is about 5.26 units per 100 units wagered over the long run.
That difference can matter a lot for frequent players, longer sessions, or higher stakes. If you’re optimizing for value, European roulette delivers a noticeably more player-friendly baseline.
FAQ: European roulette vs American roulette
Is European roulette easier to win than American roulette?
No version can make wins “easy,” because each spin is independent and random. But European roulette typically offers better odds due to the single zero and the lower roulette house edge. That’s why it’s often considered the best roulette to play from an odds perspective.
Do both games pay 35:1 on a straight bet?
Yes, standard European and American roulette usually pay 35:1 for a straight-up bet. The key difference is the number of pockets on the wheel: 37 vs 38.
What is the en prison rule and why does it matter?
The en prison rule is a player-friendly rule on some European tables for even-money bets. When 0 hits, your bet is held for the next spin rather than lost immediately, which can reduce the effective house edge on those bets.
Is la partage the same as en prison?
They are similar in spirit but not identical.La partage typically means you lose only half of your even-money stake when 0 hits.En prison typically means the full stake is held for the next spin with a chance to recover it.
Bottom line: choose the wheel that gives you more value
When comparing European roulette vs American roulette, the takeaway is refreshingly simple:
- European roulette’s single zero (37 pockets) creates a house edge around 2.7% and RTP around 97.3%.
- American roulette’s double zero (38 pockets) raises the house edge to about 5.26% and lowers RTP to about 94.74%.
- Payouts like 35:1 for straight bets are typically the same, so the wheel composition drives the difference.
- European tables may also offer en prison rule or la partage, which can further improve the effective odds on even-money bets.
If you want the best roulette to play for odds, look for a single zero European wheel, and if available, prioritize rules like en prison or la partage for an even more player-friendly experience.
