If you’ve ever searched for European vs American roulette, you’re likely after one thing: better odds. The great news is that roulette is one of the easiest casino games to compare, because the rules and payouts are broadly the same across versions. The key difference is the wheel layout, and that single detail changes the math in a big way. For more details, click to learn more.
In short: European roulette uses a single zero wheel (37 pockets) with an approximate house edge of 2.70%.American roulette adds a double zero (38 pockets total), which increases the house edge to about 5.26%. Same bets, same payouts, but a meaningfully different long-run cost.
At-a-Glance Comparison: European vs American Roulette
| Feature | European Roulette | American Roulette |
|---|---|---|
| Wheel pockets | 37 (0 to 36) | 38 (0, 00, 1 to 36) |
| Zeros | Single zero (0) | Double zero (0 and 00) |
| Approx. house edge | 2.70% | 5.26% |
| Straight-up win probability | 1 / 37 (about 2.70%) | 1 / 38 (about 2.63%) |
| Common payouts (e.g., straight-up) | Same as American (straight-up typically pays 35 to 1) | Same as European (straight-up typically pays 35 to 1) |
| Best for players seeking better odds | Yes (single zero is the advantage) | Less favorable due to 00 |
This is the core of the single zero vs double zero debate: you’re not “playing differently,” you’re paying a different price in expected value.
Rules and Wheel Layout: What Actually Changes?
European roulette wheel layout
A European roulette wheel has 37 pockets:
- Numbers 1 through 36
- One green 0
The presence of only one zero is what creates the lower house edge.
American roulette wheel layout
An American roulette wheel has 38 pockets:
- Numbers 1 through 36
- Two green pockets: 0 and 00
That extra 00 is the entire reason American roulette is usually considered the less player-friendly option.
Are the rules and bet types the same?
For most players, yes. The standard betting layout and core bet categories are the same in both versions:
- Inside bets (e.g., straight-up, split, street)
- Outside bets (e.g., red / black, odd / even, high / low)
What changes is your probability of winning each bet because the total number of pockets changes.
European vs American Roulette Odds: Why 2.7% vs 5.26% Matters
Roulette is a negative expectation game in standard casino conditions. The question isn’t whether the casino has an edge (it does), but how large that edge is.
The commonly cited comparison, roulette house edge 2.7% vs 5.26%, comes straight from the number of pockets:
- European roulette house edge is approximately 1 / 37=2.70%.
- American roulette house edge is approximately 2 / 38=5.26%.
That difference is meaningful because it impacts how long your bankroll tends to last, how volatile sessions feel over time, and how much “value” you’re getting per wager.
Why does the house edge stay consistent across bets?
In standard roulette (without special rules), the payouts are designed so the casino’s advantage comes from the zero pocket(s). Whether you bet red/black or a straight-up number, the expected loss rate is driven by the mismatch between true odds and paid odds.
Example with a straight-up bet (typical payout 35 to 1):
- European true odds of hitting a specific number: 1 / 37
- American true odds of hitting a specific number: 1 / 38
Because you’re paid as if the odds were 35 to 1 instead of 36 to 1 (European) or 37 to 1 (American), the long-run expectation is negative.
Odds and Probability Tables (European vs American)
These tables focus on popular bets players actually use, with probabilities based on the wheel pocket count.
Probability of winning common roulette bets
| Bet type | Covers | Typical payout | Win probability (European 37) | Win probability (American 38) |

| Split | 2 numbers | 17 to 1 | 2 / 37 (about 5.41%) | 2 / 38 (about 5.26%) |
| Street | 3 numbers | 11 to 1 | 3 / 37 (about 8.11%) | 3 / 38 (about 7.89%) |
| Corner | 4 numbers | 8 to 1 | 4 / 37 (about 10.81%) | 4 / 38 (about 10.53%) |
| Six line | 6 numbers | 5 to 1 | 6 / 37 (about 16.22%) | 6 / 38 (about 15.79%) |
| Dozen | 12 numbers | 2 to 1 | 12 / 37 (about 32.43%) | 12 / 38 (about 31.58%) |
| Column | 12 numbers | 2 to 1 | 12 / 37 (about 32.43%) | 12 / 38 (about 31.58%) |
| Even money (red/black, odd/even, high/low) | 18 numbers | 1 to 1 | 18 / 37 (about 48.65%) | 18 / 38 (about 47.37%) |
House edge by wheel type (standard rules)
Under standard roulette rules (no special zero-handling rules), the house edge is effectively the same across bet types for a given wheel.
| Wheel type | Zeros | Pockets | Approx. house edge |
|---|---|---|---|
| European | 1 (0) | 37 | 2.70% |
| American | 2 (0 and 00) | 38 | 5.26% |
French Roulette: The Single-Zero Upgrade Many Players Love
French roulette typically uses the same single-zero wheel as European roulette, but it may also include player-friendly rules that apply to certain outside bets (usually even-money bets like red/black).
What are la partage and en prison?
- La partage: If the ball lands on 0, an even-money bet loses only half the stake (the other half is returned).
- En prison: If the ball lands on 0, the even-money bet is “imprisoned” for the next spin; if it wins on the next spin, the player gets the stake back (exact handling can vary by house rules).
How much do these rules improve your odds?
For eligible even-money bets, these rules can reduce the effective house edge on a single-zero wheel to roughly 1.35% (about half of 2.70%). That’s a big improvement for players who like simple, low-volatility bets.
Important: these rules do not usually apply to inside bets like straight-ups, splits, or corners. They’re primarily a benefit for even-money play.
Strategy Implications: What Changes When You Switch Wheels?
Roulette strategy isn’t about “beating” the wheel in the long run (the house edge is built in). It’s about choosing conditions that maximize entertainment value and minimize expected cost.
1) Your bankroll tends to last longer on single-zero games
When you move from American roulette (about 5.26%) to European roulette (about 2.70%), you’re essentially cutting the long-run expected loss rate roughly in half. Over many spins, that can translate into longer sessions with the same budget.
2) Betting systems don’t change the house edge
Popular progression systems (like Martingale-style doubling after losses) can change the pattern of wins and losses, but they do not remove the underlying house edge. On an American wheel, a system still faces the same math as any other approach, just with different risk dynamics.
3) Even-money bettors benefit most from French rules
If you enjoy straightforward bets like red/black, choosing French roulette with la partage or en prison can be one of the most practical ways to improve the value of your play without changing how you bet.
4) The “best bet” is usually the best wheel
Because standard payouts create a consistent edge across bets, the most impactful decision is often single zero vs double zero, not whether you prefer dozens over corners. Pick the better wheel first, then choose bet types based on your preferred volatility and style.
Which Variant Should You Choose?
If your goal is better odds, the decision is refreshingly simple.
Choose European roulette if you want:
- Better expected value thanks to the 2.70% house edge
- More win probability on most bets compared to American
- A widely available format that still feels “classic” and familiar
Choose French roulette if you want:
- Everything you get with European roulette (single zero)
- Potentially even better odds on even-money bets via la partage or en prison
- A strong option for steady, lower-volatility play
Choose American roulette if you:
- Only have access to double-zero tables in your venue
- Prefer the American layout for familiarity
- Are playing primarily for the experience and don’t mind the higher cost of play
From a strictly mathematical standpoint, players seeking better odds should generally prefer single-zero roulette whenever possible.
Online vs Land-Based Play: Where You’re More Likely to Find Better Roulette
Both online and land-based casinos can offer European and American roulette, but the mix you encounter may differ by region and operator.
Online roulette: what to look for
- Wheel type: confirm single zero (European) versus double zero (American).
- Rule variants: look for French roulette and check whether la partage or en prison is offered on even-money bets.
- Game format: digital RNG roulette and live dealer roulette can both be European or American; the wheel type is still the deciding factor for edge.
Land-based roulette: what to look for
- Table signage: many venues clearly label “European” or show “0” versus “0 and 00” on the layout.
- Local norms: some destinations predominantly feature one style (for example, many European venues feature single zero more often).
- Even-money rules: if a table uses French rules, the dealer or table placard should explain how zero outcomes are handled.
Practical tip: when you’re comparing two tables with similar limits, the one with one zero is usually the better deal for your bankroll.
FAQ: European vs American Roulette
Is European roulette really better than American roulette?
Yes, in terms of odds. European roulette has 37 pockets and a house edge of about 2.70%, while American roulette has 38 pockets (with 0 and 00) and a house edge of about 5.26%.
Do European and American roulette pay the same?
Typically, yes. Standard payouts (such as 35 to 1 for a straight-up bet) are generally the same. The difference is the probability of winning due to the number of pockets.
What does “single zero vs double zero” mean?
It refers to how many green zero pockets are on the wheel. European roulette has one zero (0). American roulette has two zeros (0 and 00). That extra 00 increases the casino’s edge.
Why is the American roulette house edge 5.26%?
With two zero pockets out of 38 total pockets, the edge is roughly 2 / 38, which equals about 5.26%. This is why the double-zero wheel is considered less favorable.
Is the house edge 2.7% on every bet in European roulette?
Under standard rules, the house edge is effectively consistent across bet types on the same wheel. The wheel’s zero structure is what sets the baseline edge.
Does French roulette always have better odds than European roulette?
French roulette usually uses the same single-zero wheel as European roulette. If it also includes la partage or en prison rules for even-money bets, it can reduce the effective edge on those bets (often to around 1.35%).
Which roulette variant should beginners choose?
Beginners often do best with European roulette (single zero) because it offers better odds without requiring any extra rule knowledge. If French roulette with la partage is available, it can be an even more beginner-friendly value for even-money bets.
Bottom Line: Pick the Wheel That Gives You More Value
When you compare European vs American roulette, you’re comparing the impact of one extra pocket. That’s it. Yet the result is huge: single-zero roulette offers a lower house edge and better long-run value.
If you want the most player-friendly mainstream option, choose European roulette. If you can access French roulette with la partage or en prison for even-money bets, you’re stepping into an even better version of the same classic game. The best outcome is simple: more spins, more staying power for your budget, and a smarter way to enjoy roulette.
