European roulette and American roulette look similar at a glance, but one small design choice changes everything: the number of zero pockets on the wheel. That single detail affects your probability of winning, the casino’s built-in advantage (the roulette house edge), and how much value you get from common bets like red/black or odd/even.
If you’ve ever searched for European vs American roulette, you’re probably asking a practical question: “Which one should I play?” In most cases, the answer is simple: European roulette (and French roulette) typically offers better player value due to the single zero. But there are also rule variants, table layouts, and availability differences that can help you choose the right game with confidence.
European vs American Roulette: Quick Comparison
| Feature | European Roulette | American Roulette |
|---|---|---|
| Wheel pockets | 37 pockets (1 to 36 plus a single 0) | 38 pockets (1 to 36 plus 0 and 00) |
| Main visual cue on the table | One green zero slot | Two green slots: 0 and 00 |
| Typical house edge (most bets) | 2.70% | 5.26% |
| French rule options | Often available (especially as French roulette) | Rare |
| La Partage / En Prison impact | Can reduce edge on even-money bets | Usually not offered |
| Where you commonly see it | Many European casinos and online lobbies | Many land-based casinos in the US |
The Core Difference: Single Zero vs Double Zero
Roulette is a simple game of outcomes: a ball lands in exactly one pocket. The more pockets the casino adds without improving payouts, the more advantage shifts to the house.
European roulette wheel: 37 pockets
- Numbers: 1 to 36
- One green pocket: 0
- Total outcomes: 37
American roulette wheel: 38 pockets
- Numbers: 1 to 36
- Two green pockets: 0 and 00
- Total outcomes: 38
That extra 00 pocket is why American roulette usually has almost double the house edge of European roulette for standard bets.
Wheel Layout and Pocket Order (The Visual Difference Most Players Miss)
Beyond the number of zeros, the pocket order around the wheel differs between European and American roulette. The order matters for wheel identification and aesthetics (and for some niche approaches like wheel tracking), but it does not change the mathematical house edge by itself.
European roulette pocket order (single-zero wheel)
A standard European wheel uses this sequence (starting at 0):
0, 32, 15, 19, 4, 21, 2, 25, 17, 34, 6, 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16, 33, 1, 20, 14, 31, 9, 22, 18, 29, 7, 28, 12, 35, 3, 26American roulette pocket order (double-zero wheel)
A standard American wheel uses this sequence (starting at 0):
0, 28, 9, 26, 30, 11, 7, 20, 32, 17, 5, 22, 34, 15, 3, 24, 36, 13, 1, 00, 27, 10, 25, 29, 12, 8, 19, 31, 18, 6, 21, 33, 16, 4, 23, 35, 14, 2On the table layout, the difference is even easier to spot:
- European table: a single 0 at the top.
- American table: two green boxes at the top: 0 and 00.
Roulette House Edge: The Numbers That Drive Everything
If you want a clear, value-focused comparison, focus on the roulette house edge. This is the casino’s average advantage over the long run, expressed as a percentage of your bet.
Why the edge is 2.70% in European roulette
Most standard roulette payouts are designed as if there were only 36 outcomes (1 to 36). But European roulette has 37 outcomes because of the single zero.
For many common bets, the expected loss per unit wagered is:
House edge = 1 / 37 ≈ 0.0270 = 2.70%Why the edge is 5.26% in American roulette
American roulette has 38 outcomes due to 0 and 00:
House edge = 2 / 38 ≈ 0.0526 = 5.26%That difference is huge in practical terms. Over time, lower edge games generally allow your bankroll to last longer and make your wins (when they happen) more meaningful relative to total amount wagered.
French Roulette Rules That Can Improve Odds: La Partage and En Prison
French roulette typically uses a single-zero wheel like European roulette, but it may add special rules on even-money bets (red/black, odd/even, high/low). These rules can improve player value when the ball lands on zero.
La Partage explained
La Partage (French for “the split”) applies to even-money bets. If you bet on red/black (or similar) and the result is 0, you lose only half your stake instead of the full amount.
- Example: Bet 10 on red.
- If 0 hits: you get 5 back (lose 5).
Because zero is the only result that breaks the 18 vs 18 balance on even-money bets, La Partage effectively reduces the long-run house edge on those bets to about 1.35% on a single-zero wheel.
En Prison explained
En Prison (“in prison”) is another French rule for even-money bets. If 0 hits, your bet is not immediately lost. Instead, it is “imprisoned” for the next spin:
- If your even-money bet wins on the next spin, you typically get your original stake back (with no profit).
- If it loses on the next spin, you lose the stake.
In terms of long-run value on even-money bets, En Prison is commonly treated as similar to La Partage, producing an effective edge close to 1.35% on a single-zero wheel under typical conditions.
Key takeaway: If you enjoy red/black or odd/even style betting, a single-zero game with La Partage or En Prison can be one of the best-value mainstream roulette options you’ll find.
Bet Types and Payouts: What’s the Same (and What Changes)
The good news: European and American roulette generally share the same menu of bets and standard payouts. The difference is that the probabilities change because the number of outcomes changes.
Common roulette bets and typical payouts
| Bet type | Covers | Typical payout (profit) |
|---|---|---|
| Straight up | 1 number | 35 to 1 |
| Split | 2 numbers | 17 to 1 |
| Street | 3 numbers | 11 to 1 |
| Corner | 4 numbers | 8 to 1 |
| Six line | 6 numbers | 5 to 1 |
| Dozen | 12 numbers | 2 to 1 |
| Column | 12 numbers | 2 to 1 |
| Even-money (Red/Black, Odd/Even, 1–18 / 19–36) | 18 numbers | 1 to 1 |
Those payouts stay mostly consistent, which is exactly why the extra 00 pocket in American roulette increases the house advantage: the payouts don’t “compensate” you for the extra losing outcome.
Probability Examples: European vs American Roulette in Real Numbers
Seeing the probability difference on a few popular bets makes the comparison feel very concrete.
Example 1: Straight-up bet (one number)
- European: win probability = 1 / 37 ≈2.70%
- American: win probability = 1 / 38 ≈2.63%
The win chance is slightly lower in American roulette, but the bigger story is the expected value: the payout is still 35 to 1 in both games.
Example 2: Red or Black (even-money bet)
European roulette has 18 red, 18 black, and 1 green (0). American roulette adds another green pocket (00).
- European: P(win) = 18 / 37 ≈48.65%
- American: P(win) = 18 / 38 ≈47.37%
That ~1.28 percentage point difference may sound small, but it compounds across many spins, which is why the house edge gap is so noticeable over time.
Example 3: Dozens (1–12, 13–24, 25–36)
- European: P(win) = 12 / 37 ≈32.43%
- American: P(win) = 12 / 38 ≈31.58%
Again, the payout remains 2 to 1 in both games, so the additional pocket benefits the house rather than the player.
Common Roulette Strategy Myths (and What Actually Helps)
Roulette is exciting because it’s fast, visual, and easy to understand. That makes it a magnet for “systems” that promise to beat the wheel. Many of these ideas are entertaining, but they don’t change the underlying math of a fair, randomized roulette game.
Myth 1: The Martingale “guarantees” profit
The Martingale (doubling after losses on an even-money bet) is often pitched as a near-certain way to win a small amount. In reality, it runs into two practical limits:
- Table limits stop you from doubling forever.
- Bankroll limits stop most players even sooner.
Even if you win frequently, one long losing streak can erase many small gains quickly.
Myth 2: Past spins predict the next spin (the “hot” and “cold” fallacy)
In standard roulette, each spin is independent. A long streak of red does not make black “due” on the next spin. Tracking outcomes can be fun, but it does not change the next-spin probability in a typical casino or regulated online game.
Myth 3: Betting systems reduce the house edge
Bet sizing and bet selection can change your volatility (how swingy your results feel), but they do not remove the built-in advantage of the wheel. If your goal is better value, the most reliable “strategy” is choosing variants with a lower house edge, such as:
- European roulette instead of American roulette
- French roulette with La Partage or En Prison for even-money bets
Which Roulette Variant Is Best for You?
Different roulette games can match different play styles. Here’s a practical way to choose based on what you value most.
If you want the best general odds
- Pick European roulette (single zero) when available.
- If you see French rules like La Partage or En Prison, that can be even better for even-money bettors.
If you love even-money bets (red/black, odd/even)
- Look specifically for La Partage or En Prison tables.
- These rules are designed to soften the impact of the zero result on even-money wagers.
If you’re playing mainly for atmosphere and tradition
- American roulette is common in many US casinos and has a classic presence on casino floors.
- European roulette is widely popular internationally and commonly offered online, making it easy to find.
No matter your style, recognizing the wheel type is a high-impact skill: spotting 0 versus 0 and 00 can be the difference between a lower-edge and higher-edge session.
Regional and Online Availability: Where You’ll Commonly Find Each Game
Availability often comes down to geography and platform.
Land-based casinos
- United States: American roulette is common; some venues also offer European (single-zero) wheels, but it varies.
- Many European destinations: European and French roulette are widely seen, often with single-zero wheels.
Online casinos
- Online platforms often offer multiple roulette variants side-by-side, including European roulette, American roulette, and French roulette, and online blackjack.
- Live dealer tables frequently label the variant clearly, and the felt layout makes it easy to confirm if 00 is present.
For value-focused play online, it can be worth taking a moment to choose the single-zero version when you have the option.

FAQs
Is European roulette better than American roulette?
European roulette is generally considered better value because it has a single zero on a 37-slot wheel, producing a typical house edge of about 2.70%. American roulette adds a 00 pocket (38 slots total), which typically raises the house edge to about 5.26%.
What is the house edge in roulette?
The house edge is the casino’s average advantage over time. In most standard roulette games, it’s mainly determined by the number of zero pockets:
- European roulette: about 2.70%
- American roulette: about 5.26%
Does the pocket order on the wheel change the odds?
The pocket order (the sequence of numbers around the wheel) differs between European and American wheels, but it does not change the mathematical odds in a standard, fair game. The biggest odds difference comes from one zero versus two zeros.
What does La Partage mean in roulette?
La Partage is a French roulette rule for even-money bets. If the ball lands on 0, you lose only half your stake (instead of losing the full amount). This reduces the effective house edge on even-money bets on a single-zero wheel to about 1.35%.
What is En Prison in roulette?
En Prison is another French rule for even-money bets. If 0 hits, your stake is held for the next spin rather than lost immediately. Depending on the next result, you may get your stake back (typically without profit) or lose it. Like La Partage, it improves value on even-money bets compared with standard European rules.
Are payouts different in European vs American roulette?
Most standard payouts (like 35 to 1 for a straight-up number) are the same in both variants. The key difference is that American roulette adds an extra losing pocket (00) without increasing payouts, which is why the house edge is higher.
What is the best roulette bet?
From a house-edge perspective, many standard bets share the same edge within a given roulette variant. The biggest improvement comes from choosing the right game:
- Best overall value: single-zero European roulette
- Best even-money value: French roulette with La Partage or En Prison
Bottom Line: A One-Second Check That Can Improve Your Odds
If you remember just one practical tip, make it this: check the zeros. A single-zero wheel usually means a house edge around 2.70%, while a double-zero wheel commonly means around 5.26%. And if you spot French rules like La Partage or En Prison on even-money bets, you may be looking at an even more player-friendly version of roulette.
Roulette will always have built-in casino advantage, but choosing the right variant is a smart, positive step toward longer sessions, better value, and a game experience that rewards informed decisions.
