If you’ve ever wondered why some roulette tables feel more “player-friendly” than others, the answer is usually simple: European vs American roulette comes down to the wheel layout, which directly changes the roulette house edge, your long-term expected results, and even how the game “swings” in the short run.
Both versions look nearly identical at a glance, and the payouts are typically the same. Yet a single extra pocket on the American wheel makes a measurable difference. The good news: once you understand how single zero roulette and double zero roulette are built, choosing the better option becomes easy.
The Core Difference: Wheel Layout (37 vs 38 Pockets)
The defining distinction is the number of pockets on the wheel:
- European roulette has 37 pockets: numbers 1 to 36 plus a single zero (0).
- American roulette has 38 pockets: numbers 1 to 36 plus a single zero (0) and a double zero (00).
That extra 00 is not just cosmetic. It increases the casino’s advantage and slightly reduces your chances of hitting any bet that depends on “number of pockets” math (which is basically all of them).
Roulette House Edge: 2.70% vs 5.26%
The most player-relevant number in roulette is the roulette house edge (also called the house advantage). This is the average percentage of each bet the casino expects to keep over time, assuming standard payouts.
- European roulette house edge: about 2.70%
- American roulette house edge: about 5.26%
In other words, American roulette’s edge is roughly almost double the European edge. If you’re comparing tables and you have a choice, this difference alone is a powerful reason to prefer single zero roulette.
Why the Edge Changes (Without Changing the Payouts)
Roulette payouts are generally standardized (for example, a straight-up number pays 35 to 1). The catch is that payout assumes odds closer to 36-to-1. When the wheel adds extra zero pockets, the true odds worsen, but the payout stays the same. That gap is where the house edge lives.
European vs American Roulette: Quick Comparison Table
| Feature | European Roulette | American Roulette |
|---|---|---|
| Number of pockets | 37 | 38 |
| Zero pockets | 0 | 0 and 00 |
| Typical house edge | ~ 2.70% | ~ 5.26% |
| Common name | Single zero roulette | Double zero roulette |
| Player-friendly special rules | Often includes En Prison or La Partage | Less common |
| Best for long-term value | Yes | Usually no |
How the Extra Zero Affects Roulette Odds and Strategy
When you add an extra pocket, every single bet becomes slightly harder to hit. This is the simplest way to think about roulette odds and strategy: the betting menu may look the same, but the probability behind each option shifts.
Example: Straight-Up Number Bet
A straight-up bet (one number) typically pays 35 to 1 in both versions.
- European probability of winning: 1 / 37
- American probability of winning: 1 / 38
This difference looks small, but it’s consistent across every spin and every bet. Over many spins, that consistency is exactly what turns into a higher house edge on the American wheel.
Example: Even-Money Bets (Red/Black, Odd/Even, High/Low)
Even-money bets pay 1 to 1, but they aren’t truly 50/50 because the zero pockets are neither red nor black, neither odd nor even, and neither high nor low.
- European: 18 winning outcomes, 18 losing outcomes, plus 0 as an extra losing outcome.
- American: 18 winning outcomes, 18 losing outcomes, plus 0 and 00 as extra losing outcomes.
The result: even-money bets “feel” similar, but the extra zero makes them lose slightly more often in American roulette.
Volatility: Does American Roulette Swing More?
Players often describe roulette as “streaky,” and you can absolutely experience hot and cold runs in both versions. The extra 00 in double zero roulette mainly does two things:
- Reduces hit frequency a bit for all bets, which can make dry spells feel more common for a given betting pattern.
- Increases the long-run cost of playing the same way, because the house edge is higher.
That said, the biggest driver of volatility is still your bet type. Higher-risk bets (like single numbers) will swing more than even-money bets on both wheels. Choosing European roulette doesn’t eliminate volatility, but it does give you better long-term value while you play.
Payouts and Betting Options: Mostly the Same, but Not Equally Profitable
One reason roulette is so approachable is that the bet types are straightforward. In most casinos, European and American roulette share the same core betting options and payouts.
Common Outside Bets (Lower Risk)
- Red / Black (1 to 1)
- Odd / Even (1 to 1)
- High (19–36) / Low (1–18) (1 to 1)
- Dozens (1–12, 13–24, 25–36) (2 to 1)
- Columns (2 to 1)
Common Inside Bets (Higher Risk)
- Straight-up (single number) (35 to 1)
- Split (two numbers) (17 to 1)
- Street (three numbers) (11 to 1)
- Corner (four numbers) (8 to 1)
- Six line (six numbers) (5 to 1)
The key takeaway: the payouts don’t typically improve on the American wheel to compensate for the extra pocket. So if you play the same bets with the same bankroll, the European layout generally offers a better expected return.
The Big European Bonus: En Prison and La Partage
Many European roulette tables offer special rules designed to soften the impact of the zero on even-money bets. Two famous examples are En Prison and La Partage. If you enjoy betting red/black or odd/even, these rules can be a major upgrade.
La Partage ("Sharing")
With La Partage, if you place an even-money bet and the ball lands on 0, you typically lose only half your stake (the other half is returned).
Benefit: this can reduce the effective house edge on even-money bets on a European wheel from ~2.70% to roughly 1.35%, because the zero no longer takes the full bet.
En Prison ("In Prison")
With En Prison, if you place an even-money bet and the result is 0, your bet is “imprisoned” for the next spin instead of losing immediately.
- If your bet wins on the next spin, you usually get your stake back (often without extra profit).
- If it loses on the next spin, you lose the stake.
Benefit: like La Partage, En Prison can improve the value of even-money bets and is widely viewed as a player-friendly rule on single-zero tables.
If you see a single zero roulette table with La Partage or En Prison, you’re looking at one of the best mainstream roulette setups for players who enjoy outside bets.
Practical Advice: Which Roulette Should You Play?
Choose European Roulette When You Have the Option
If your goal is better long-term value, the recommendation is straightforward: prefer European vs American roulette in favor of the European wheel whenever it’s available. The lower roulette house edge means more of your bankroll stays in play over time, which can translate into longer sessions and more entertainment per dollar.
Prioritize Single Zero Over Double Zero
Think in these simple terms:
- Single zero roulette is the “better odds” default.
- Double zero roulette is the “higher house edge” alternative.
Even if you don’t track percentages, consistently choosing the single-zero wheel is one of the cleanest, most reliable improvements you can make without changing your play style.
If You Like Even-Money Bets, Look for En Prison or La Partage
For players who enjoy lower-volatility outside betting, these rules can be a meaningful edge reducer. They don’t turn roulette into a beatable game in the long run, but they do improve expected outcomes compared to the same bets without those rules.
Roulette Odds and Strategy: Smart Habits That Pair Well with European Tables
The roulette game is a game of chance, and no betting system changes the built-in house edge over the long run. Still, you can make decisions that improve your experience and keep your play intentional.
1) Match Bet Type to Your Goal
- If you want lower volatility, focus on outside bets (red/black, odd/even, high/low) and consider European tables with En Prison or La Partage.
- If you want high payouts, inside bets like straight-ups deliver big wins when they hit, but expect larger swings.
2) Use the House Edge as Your “Table Filter”
Instead of overthinking patterns or past spins, filter your choices by structure:
- Pick single zero roulette over double zero.
- Prefer player-friendly rules when available.
This is one of the few roulette decisions that consistently improves expected value.
3) Treat Volatility as a Feature You Can Control
You can’t control outcomes, but you can control how wild your session feels. Smaller bet sizes and more outside betting typically create smoother session curves, while inside bets increase variance. On a European wheel, your money tends to last longer at the same pace because the underlying disadvantage is lower.
Bottom Line: European Roulette Delivers Better Value Spin After Spin
When comparing European vs American roulette, the headline is clear: European roulette’s single zero layout (37 pockets) produces a standard house edge around 2.70%, while American roulette’s double zero layout (38 pockets) raises it to about 5.26%.
Add in European-friendly rules like En Prison and La Partage, and the gap can grow even wider for even-money bets. If you’re looking for better odds, longer-lasting bankrolls, and a more player-optimized experience, choosing single zero roulette is one of the smartest moves you can make before the first spin.
Quick FAQ
Is European roulette always better than American roulette?
From a house edge perspective, yes: the single-zero wheel is generally more favorable. Individual experiences vary in the short run, but the math advantage is consistently better in European roulette.
Does La Partage or En Prison apply to all bets?
Typically, these rules apply to even-money bets (like red/black). They usually do not apply to dozens, columns, or inside bets.
Do betting systems overcome the roulette house edge?
No betting system changes the built-in house edge over the long run. The most reliable improvement is choosing a game with better rules and a lower edge, such as European roulette and especially tables featuring La Partage or En Prison.
