If you’ve ever wondered why some roulette tables feel “friendlier” than others, the answer is usually not the dealer, the vibe, or even your roulette strategy. It’s the wheel layout. The biggest difference in European vs American roulette is simple but powerful: single zero versus double zero.
That extra pocket changes the math for every bet on the layout. Payouts and bet types stay the same, but your odds shift slightly against you on an American wheel. The good news is that once you understand the house edge and a few practical habits (like bankroll management), you can make smarter choices quickly and confidently.
At a Glance: The Core Difference (Wheel Layout)
Both roulette versions use the same numbers from 1 to 36, split into red and black. What changes is the green pocket(s):
- European roulette: numbers 1–36 plus a single zero (0) for a total of 37 pockets.
- American roulette: numbers 1–36 plus a single zero (0) and a double zero (00) for a total of 38 pockets.
Everything else being equal, adding one more losing pocket (relative to most bets) increases the casino’s built-in advantage.
House Edge Explained (Why the Extra Pocket Matters)
House edge is the casino’s average advantage over the long run, expressed as a percentage of each bet. It doesn’t predict short sessions, but it’s a reliable way to compare games.
European roulette house edge
With 37 pockets, the standard house edge is:
1 / 37 = 2.70% (rounded)
That corresponds to an RTP (return to player) of about:
97.30%
American roulette house edge
With 38 pockets, the standard house edge is:
2 / 38 = 5.26% (rounded)
That corresponds to an RTP of about:
94.74%
Key takeaway: American roulette roughly doubles the house edge compared to European roulette. That’s a meaningful gap, especially if you play longer sessions or higher stakes.
Payouts and Bet Types: Mostly the Same, But the Odds Shift
A common misconception is that American roulette changes payouts. In standard rules, it doesn’t. A straight-up number still pays 35:1, a dozen still pays 2:1, and even-money bets still pay 1:1.
What changes is the probability of winning each bet because there’s one extra pocket on the wheel.
How the extra pocket affects typical bets
| Bet type | Typical payout | Win chance (European, 37) | Win chance (American, 38) | Why it changes |
|---|---|---|---|---|
| Even-money (Red/Black, Odd/Even, High/Low) | 1:1 | 18 / 37 (48.65%) | 18 / 38 (47.37%) | Same 18 winning numbers, more total pockets |
| Dozen / Column | 2:1 | 12 / 37 (32.43%) | 12 / 38 (31.58%) | Same 12 winners, more total pockets |
| Street (3 numbers) | 11:1 | 3 / 37 (8.11%) | 3 / 38 (7.89%) | Same 3 winners, more total pockets |
| Straight-up (1 number) | 35:1 | 1 / 37 (2.70%) | 1 / 38 (2.63%) | Same 1 winner, more total pockets |
Notice how the payout doesn’t improve to compensate for the extra pocket. That’s exactly why the house edge rises.
The French Variation: “La Partage” and “En Prison” (A Player-Friendly Upgrade)
If you want an even better version of the single zero game, look for French roulette rules that include la partage or en prison. These rules mainly benefit even-money bets (like red/black jack online or odd/even).
What is la partage?
La partage means “sharing.” On an even-money bet, if the ball lands on 0, you lose only half your stake instead of the full amount.
What is en prison?
En prison (“in prison”) is similar: on an even-money bet, if the ball lands on 0, your bet is “imprisoned” for the next spin. If your bet wins on the next spin, you get your stake back (typically without profit); if it loses, you lose the stake. In many standard rule sets, this produces the same long-run value as la partage for even-money bets.
How much can these rules improve RTP?
On a standard European wheel, the house edge is 2.70%. With la partage or en prison, the house edge on even-money bets can drop to about:
1.35% (roughly half of 2.70%)
That implies an RTP of about:
98.65% (for even-money bets under these rules)
Benefit-driven insight: If you like steady, lower-volatility play (for example, red/black with disciplined session limits), French rules can meaningfully stretch your bankroll compared to standard European roulette, and especially compared to American roulette.
Geographic Availability: Where You’ll Commonly Find Each Wheel
Availability is a practical factor when choosing European vs American roulette, especially if you travel or switch between land-based and online play.
- Europe: single zero (European roulette) is widely common, and French-rule variants are more likely to appear in European-style casinos.
- United States: many land-based casinos traditionally use double zero (American roulette), though some venues offer single-zero tables as a premium option.
- Online casinos: European roulette (single zero) is very common online, and it’s often easy to find tables that explicitly list la partage or en prison in the rules.
Player win: Because online lobbies typically label the rule set, it’s often easier to consistently choose a lower house edge game online than it is on a busy casino floor.
European vs American Roulette: Which One Should You Choose?
If your goal is to improve your long-run value (without changing the classic roulette experience), the hierarchy is straightforward:
- Best for even-money bets:single zero with la partage or en prison (about 1.35% house edge on even-money bets).
- Solid default choice: standard European roulette (2.70% house edge).
- Least favorable (standard rules): American roulette with double zero (5.26% house edge).
Because bet types and payouts are basically the same, choosing the wheel is one of the highest-impact decisions you can make before placing a single chip.
Practical Player Tips: Simple Choices That Improve Your Results
Roulette is a negative-expectation game under standard rules, so the most reliable way to “play smarter” is to reduce the built-in disadvantage and manage your session risk. Here are practical, player-first habits that can help you get more entertainment and more time at the table per bankroll.
1) Prefer single zero whenever possible
This is the cleanest upgrade you can make. Choosing single zero over double zero cuts the standard house edge from about 5.26% to 2.70%.
2) Actively look for la partage or en prison (if you play even-money bets)
If your preferred approach involves red/black, odd/even, or high/low, French rules can be a big value boost by lowering the house edge on those bets to about 1.35%.
3) Know the RTP you’re actually playing
When comparing tables, keep these benchmark RTP figures in mind:
- European roulette RTP: about 97.30% (standard rules)
- American roulette RTP: about 94.74% (standard rules)
- French rules RTP (even-money bets): about 98.65%
Even small percentage differences matter over many spins.
4) Use bankroll management as your main “strategy”
A sustainable roulette strategy is less about “beating” the wheel and more about controlling volatility and avoiding preventable mistakes.
- Set a session bankroll you’re comfortable losing, and treat it as the total cost of entertainment.
- Choose a unit size (for example, 1% to 2% of your session bankroll) to reduce the chance of busting quickly.
- Set a stop-loss and a win goal so a good run doesn’t turn into a long chase, and a bad run doesn’t spiral.
These habits don’t change the math, but they can dramatically improve how your sessions feel and how long you can play.
5) Be cautious with aggressive progression systems
Systems that increase stakes after losses (often marketed as a “sure thing”) can create large bets quickly. Even when a progression wins often, the occasional long losing streak can be expensive—especially on a higher house edge wheel like double zero.
If you enjoy structure, consider flat betting or mild, pre-planned adjustments instead of unlimited progressions.
A Quick Example: How Table Choice Can Change a Session
To keep things factual, this is a simplified illustration (not a promise of results). Suppose two players each make 200 spins of $10 even-money bets:
- Player A chooses standard European roulette (2.70% house edge).
- Player B chooses standard American roulette (5.26% house edge).
The expected loss is approximately:
- European: 200 × $10 × 2.70% =$54
- American: 200 × $10 × 5.26% =$105.20
Variance will dominate short-term outcomes, but over time, the wheel with the lower house edge generally costs less to play. This is why picking single zero is one of the most practical “moves” in roulette.
FAQ: European vs American Roulette
Is European roulette “easier to win” than American roulette?
The payouts are the same, but the probabilities are better on a single zero wheel. That’s why European roulette has a lower house edge (about 2.70%) than American roulette (about 5.26%).
Do the bet types change between versions?
Standard inside and outside bet types are essentially the same. The difference is the wheel pockets (0 vs 0 and 00), which shifts the odds.
Does la partage or en prison apply to all bets?
Typically, these French rules apply to even-money bets. They don’t usually improve the house edge for bets like straight-ups, splits, or dozens.
What’s the best “roulette strategy” for beginners?
Start with table selection: prefer single zero, and choose la partage or en prison when available. Then use simple bankroll management (flat betting, clear limits) to keep play controlled and enjoyable.
Bottom Line: Choose the Wheel First, Then Play Your Style
When comparing European vs American roulette, the headline is the green pocket count: single zero (37) versus double zero (38). With the same payouts, the extra pocket pushes the house edge from about 2.70% up to roughly 5.26%, making American roulette a noticeably pricier game over time.
If you want an even better value option, French roulette with la partage or en prison can cut the edge on even-money bets to about 1.35%. Add smart bankroll management, and you have a realistic, benefit-focused way to get more from every session—without changing what makes roulette fun in the first place.
