If you’re comparing European vs American roulette, you’re already doing the smartest thing most players can do: focusing on the mechanics that drive the math. Roulette looks simple, but the wheel type, pocket count, and rules behind even-money bets can change your long-term value dramatically.
This guide breaks down the real-world differences between European and American roulette, including wheel layouts, house edge, special rules like En Prison and La Partage, and how those changes affect roulette odds, bankroll, and strategy. You’ll also see quick numerical examples and a side-by-side comparison table you can reference anytime.

At a Glance: The One Difference That Changes Everything
The biggest difference is the number of green zero pockets on the wheel:
- European roulette uses a single-zero wheel: numbers 1–36 plus 0 (total 37 pockets). This is often referred to as single zero rulet.
- American roulette uses a double-zero wheel: numbers 1–36 plus 0 and 00 (total 38 pockets).
That extra 00 pocket is not just a cosmetic change. It increases the casino’s built-in advantage, meaning the average cost of placing the same bets is higher over time.
European vs American Roulette: Comparison Table
| Feature | European Roulette | American Roulette |
|---|---|---|
| Wheel pockets | 37 (1–36 + 0) | 38 (1–36 + 0 + 00) |
| Zero pockets | Single zero (0) | Double zero (0 and 00) |
| Typical house edge | ~ 2.70% | ~ 5.26% |
| Even-money bet example | Red / Black, Odd / Even, High / Low | Red / Black, Odd / Even, High / Low |
| Special rules sometimes offered | En Prison and La Partage (varies by venue) | Usually not offered |
| Layout (table) | Typically a more compact layout; 0 at the top | Includes both 0 and 00; layout accommodates the extra pocket |
| Value for players | Better expected value due to lower edge | Lower expected value due to higher edge |
Roulette Odds Explained: Why the House Edge Is ~ 2.7% vs ~ 5.26%
Roulette payouts are designed around a 36-number payoff structure, but the wheel contains 37 or 38 pockets. That mismatch is where the casino edge comes from.
European roulette house edge (~ 2.70%)
On a single-zero wheel, the chance of hitting a specific pocket is:
- 1 / 37 per number
For an even-money bet (like Red), you win 1 unit when you hit your color and lose 1 unit otherwise. If we assume standard rules where the zero makes you lose the bet, the expected loss per unit wagered is:
- Expected loss = 1 / 37 ≈ 0.027027→2.7027%
American roulette house edge (~ 5.26%)
On a double-zero wheel, the chance of landing on either green pocket (0 or 00) is:
- 2 / 38
With standard rules, either green pocket causes an even-money bet to lose. So:
- Expected loss = 2 / 38 ≈ 0.052632→5.2632%
What this means in plain terms: the American wheel roughly doubles the average cost of playing compared to the European wheel when you’re making comparable bets.
Numerical Examples: What the Difference Looks Like in Real Money
It’s easier to feel the difference when you see the expected loss in familiar numbers. These examples use long-run averages (individual sessions will vary, sometimes widely).
Example 1: A $10 even-money bet repeated 100 times
- European roulette: total wagered = $1,000. Expected loss ≈ $1,000 × 0.027027 =$27.03.
- American roulette: total wagered = $1,000. Expected loss ≈ $1,000 × 0.052632 =$52.63.
Player benefit: choosing European roulette can mean keeping roughly $25.60 more per $1,000 wagered on even-money bets, on average.
Example 2: A $5 straight-up bet (single number)
The payout for a straight-up win is typically 35 to 1 in both versions, but the win probability differs because the wheel differs.
- European: win probability = 1/37. Expected value per $5 ≈ $5 × (35/37 − 36/37) =−$0.135 (about 2.70% of $5).
- American: win probability = 1/38. Expected value per $5 ≈ $5 × (35/38 − 37/38) =−$0.263 (about 5.26% of $5).
Takeaway: the payout looks the same, but the extra pocket quietly makes each bet more expensive over time.
Table Layout Differences: What You’ll Notice as a Player
The table layout is more than aesthetics. It affects how quickly you place bets, how intuitive the game feels, and sometimes which side bets are available.
European roulette layout
- Typically shows a single green 0 at the top of the betting grid.
- Often feels more compact because there’s one fewer special pocket to accommodate.
- Common in European-style casinos and many online roulette lobbies.
American roulette layout
- Includes both green 0 and 00, usually displayed side-by-side at the top.
- That extra zero influences not only odds, but also the “flow” of betting for new players learning outside bets.
Image suggestion (no download required): Create a simple side-by-side diagram showing a European wheel with 0 and an American wheel with 0 and 00. Label total pockets: 37 vs 38. Add a callout: “Extra 00 doubles the house edge.”
Rule Differences That Can Improve Your Odds: En Prison and La Partage
Beyond the wheel itself, European roulette sometimes offers rules that can improve the value of even-money bets (Red/Black, Odd/Even, High/Low). These rules don’t typically apply to other bet types.
La Partage (often on single-zero tables)
If you place an even-money bet and the ball lands on 0:
- You lose only half your bet (the other half is returned).
Why it matters: this reduces the house edge on even-money bets from ~ 2.70% down to about 1.35% on those specific bets.
En Prison (often on single-zero tables)
If you place an even-money bet and the ball lands on 0:
- Your bet is “imprisoned” for the next spin.
- If your bet wins on the next spin, you typically get your stake back (without profit), and if it loses, you lose it.
Why it matters: the math benefit is similar to La Partage for even-money bets, effectively lowering the long-run cost compared to standard single-zero rules.
Important note: availability varies by casino and by table, so it’s worth checking the table rules before you play.

Payouts: What Stays the Same (and What That Implies)
A key reason roulette feels consistent across versions is that the payout table is usually the same (for standard bets), even though the wheel probabilities differ.
Common roulette bets and payouts
| Bet type | Covers | Typical payout | Why version matters |
|---|---|---|---|
| Straight-up | 1 number | 35 to 1 | Win probability differs (1/37 vs 1/38) |
| Split | 2 numbers | 17 to 1 | Win probability differs by wheel size |
| Street | 3 numbers | 11 to 1 | Same payout, different probability |
| Corner | 4 numbers | 8 to 1 | Same payout, different probability |
| Dozen / Column | 12 numbers | 2 to 1 | Zero pockets hurt these bets too |
| Even-money outside | 18 numbers | 1 to 1 | Largest impact from 0 (and 00), improved by La Partage / En Prison |
Strategy implication: because payouts don’t “compensate” for the extra pocket in American roulette, the long-term expected value is worse for the player on every standard bet type.
Strategy Implications: How the Wheel Changes Your Best Choices
Roulette strategies often focus on bet selection, session goals, and bankroll management rather than changing the underlying odds (because the house edge is built into the game). Still, choosing the right version of roulette is a meaningful edge in itself.
1) If you can choose, prioritize single-zero roulette
- European single-zero generally offers better value than American double-zero.
- If La Partage or En Prison is available, even-money bets can become especially cost-efficient.
2) Outside bets become more attractive with La Partage / En Prison
Even-money bets don’t become “winning” bets long-term, but lowering the house edge can help your bankroll last longer and make session-based goals (like time-on-table) more achievable.
3) Be cautious about confusing coverage with better odds
Many players spread bets (like dozens, columns, or multiple splits) to “cover more numbers.” That can reduce swinginess per spin, but it doesn’t remove the house edge. The wheel type still determines the long-run cost.
4) Keep the “rulet razlika” simple: fewer green pockets is better
If you remember one phrase for rulet razlika, make it this: one zero beats two. Everything else is secondary compared to that built-in math difference.
Choosing the Right Table: A Quick Checklist
- Look at the wheel or felt: do you see 00? If yes, it’s American roulette.
- Check table rules: are La Partage or En Prison listed for even-money bets? Check the casino or an online blackjack site for table rules.
- Confirm minimum bets: a lower house edge is most useful when the minimum fits your bankroll comfortably.
- Avoid assumptions:“European-style” branding is not the same as a guaranteed single-zero wheel. Verify the 0 / 00.
FAQ: European vs American Roulette
Is European roulette always better than American roulette?
From a mathematical expected-value standpoint, yes in standard forms, because the single-zero wheel typically has a ~ 2.7% house edge versus ~ 5.26% for the double-zero wheel. If La Partage or En Prison is available on a single-zero table, European roulette can be even more favorable for even-money bets.
What does “single zero rulet” mean?
Single zero rulet refers to roulette played on a wheel with only one green zero pocket, 0, for a total of 37 pockets. It’s the standard wheel for European roulette and is associated with a lower house edge.
Why does American roulette have a higher house edge?
Because it adds an extra green pocket, 00, increasing the total pockets to 38 while keeping the same common payouts. That extra pocket increases the probability that all standard bets lose, raising the long-run expected loss for players.
Do payouts differ between European and American roulette?
For standard bets, payouts are typically the same (for example, 35 to 1 on a straight-up number). The difference is that the win probability changes with the wheel size, which is why the house edge differs.
What are La Partage and En Prison, and do they apply to all bets?
They are rules usually tied to even-money bets on some single-zero tables. They do not generally apply to inside bets like straight-up numbers, splits, or corners. When available, they can reduce the effective house edge on even-money bets to about 1.35%.
How can I quickly tell whether I’m on a European or American table?
Check for 00. If the layout shows both 0 and 00, it’s American roulette. If there’s only 0, it’s European roulette.
Key Takeaway
The most important factor in European vs American roulette is the wheel: single-zero roulette generally offers better value than double-zero roulette. Add in special rules like La Partage or En Prison, and you can further improve the value of even-money bets. If your goal is to get more play, more spins, and better long-run efficiency from your bankroll, choosing the right roulette variant is one of the simplest upgrades you can make.
