European and American roulette look almost identical at a glance: same felt layout, the same iconic spin, and the same headline payouts (like 35:1 on a straight-up number). The difference that matters most, though, is simple and powerful: the wheel.
European roulette uses a single-zero wheel with 37 pockets (0–36). American roulette uses a double-zero wheel with 38 pockets (0–36 plus 00). That extra 00 pocket increases the casino advantage significantly, which directly affects your long-term results.
Below you’ll find a clear comparison of house edge and RTP, concrete probability and payout examples (straight, split, and outside bets), rule variations such as La Partage and En Prison that can reduce the edge, plus wheel diagrams, wheel sequences, and practical tips to help you pick the most player-friendly roulette variant.
Quick Comparison: European vs American Roulette at a Glance
| Feature | European Roulette | American Roulette |
|---|---|---|
| Wheel pockets | 37 (0–36) | 38 (0–36 plus 00) |
| Zero pockets | Single zero (0) | Single zero (0) and double zero (00) |
| House edge (most standard rules) | About 2.70% | About 5.26% |
| RTP (return to player) | About 97.30% | About 94.74% |
| Payouts (e.g., straight-up) | Same (straight-up pays 35:1) | Same (straight-up pays 35:1) |
| Special rules that can lower edge | Often available (especially French roulette): La Partage/En Prison | Less common; some tables offer variants, but standard is higher edge |
Wheel Layout: The One Extra Pocket That Changes Everything
The core reason European roulette is usually recommended is that it has one fewer losing pocket. With a single zero, there are 37 outcomes; with double zero, there are 38 outcomes. Because standard payouts were designed around a 36-number game (1–36), the zero(s) create a built-in advantage for the casino.
Simple Wheel Diagrams (Pocket Count)
| Variant | Pockets | Diagram (conceptual) |
|---|---|---|
| European | 37 | 0 + 1–36 |
| American | 38 | 0 + 00 + 1–36 |
This looks like a tiny change, but it nearly doubles the house edge on American roulette compared to European roulette.
House Edge and RTP: European (2.70%) vs American (5.26%)
House edge is the casino’s expected profit as a percentage of each bet, over the long run. RTP is the flip side (roughly 100% - house edge).
- European roulette: house edge ≈2.70%, RTP ≈97.30%
- American roulette: house edge ≈5.26%, RTP ≈94.74%
To see how this plays out in practical terms, imagine you place $10 bets repeatedly:
- On a European wheel, the expected loss is about $0.27 per $10 bet (on average, over time).
- On an American wheel, the expected loss is about $0.53 per $10 bet (on average, over time).
That difference can translate into noticeably longer play sessions and a better chance to enjoy the natural swings of roulette before the math catches up.
Do European and American Roulette Have the Same Payouts?
Yes. In standard roulette, the main bet types and their payouts are the same in both variants. What changes is the probability of winning due to the extra 00 pocket on American wheels.
Standard Roulette Payout Table (Same in Both Variants)
| Bet type | Covers | Typical payout |
|---|---|---|
| Straight-up | 1 number | 35:1 |
| Split | 2 numbers | 17:1 |
| Street | 3 numbers | 11:1 |
| Corner | 4 numbers | 8:1 |
| Six line | 6 numbers | 5:1 |
| Dozen / Column | 12 numbers | 2:1 |
| Even-money (Red/Black, Odd/Even, High/Low) | 18 numbers | 1:1 |
Probability Examples: Straight-Up, Split, and Outside Bets
Because American roulette has one additional pocket, your chance of winning any bet that depends on a single spin is slightly lower. That small drop in probability is exactly what produces the higher house edge.
Straight-Up Bet (35:1) Probability and Expected Value
Straight-up means betting on one exact number.
- European: win probability =1 / 37≈2.7027%
- American: win probability =1 / 38≈2.6316%
Assume a $1 straight-up bet pays 35:1 (you win $35 profit, and typically receive your $1 stake back as well). The expected value (EV) in profit terms can be expressed as:
EV = P(win) * 35 + P(lose) * (-1)
- European EV:
(1/37)*35 + (36/37)*(-1) = -1/37≈-0.0270 (about -2.70%) - American EV:
(1/38)*35 + (37/38)*(-1) = -2/38≈-0.0526 (about -5.26%)
Same payout, different math. The American wheel’s extra pocket makes every straight-up attempt slightly less likely to hit, and that difference compounds over time.
Split Bet (17:1) Probability and Expected Value
A split covers two adjacent numbers on the layout.
- European: win probability =2 / 37≈5.4054%
- American: win probability =2 / 38≈5.2632%
With a $1 split paying 17:1, the EV in profit terms is:
EV = P(win) * 17 + P(lose) * (-1)
- European EV:
(2/37)*17 + (35/37)*(-1) = -1/37≈-2.70% - American EV:
(2/38)*17 + (36/38)*(-1) = -2/38≈-5.26%
This illustrates an important roulette principle: on standard bets, the house edge stays constant within the same wheel type. The wheel (single zero vs double zero) is the big lever.
Outside Even-Money Bet (Red/Black) Probability
Even-money bets like Red/Black, Odd/Even, and 1–18/19–36 are popular because they hit more often. But they still lose when the ball lands on 0 (and 00 on American wheels).
- European: win probability =18 / 37≈48.6486%
- American: win probability =18 / 38≈47.3684%
Even-money bets are a great example of how the extra 00 doesn’t change payouts, but it does change how often you win and how often you get caught by the zeros.
Volatility and Variance: How the Extra 00 Changes the “Feel” of the Game
Roulette naturally has swings: you can win several bets in a row, then hit a rough patch. Two related concepts shape that experience:
- Variance: how widely outcomes fluctuate around the average in the short run.
- Volatility (informal casino term): how “swingy” the ride feels for a given bet style.
The 00 on American roulette doesn’t change the payout schedule, so the game doesn’t suddenly become a different genre. But it does change the probability of each outcome enough to:
- Increase the casino’s long-run advantage (higher expected loss per unit wagered).
- Slightly reduce hit frequency on many bets (for example, red hits 18/38 instead of 18/37).
- Increase the likelihood that zeros interrupt even-money streaks (because there are more zero outcomes overall).
For players who enjoy steadier pacing, European or French roulette often feels more forgiving simply because fewer spins land on a zero pocket.
Wheel Sequence Differences: European vs American Number Order
In addition to pocket count, the physical order of numbers around the wheel differs between European and American roulette. For most casual play, this doesn’t change the math of standard bets. However, the sequence can matter for:
- Neighbor bets (bets on a number and its adjacent wheel neighbors), common in French-style roulette.
- Players who track outcomes for entertainment and pattern-watching (even though each spin is independent on a fair wheel).
European Wheel Sequence (Single Zero)
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, 26
American Wheel Sequence (Double Zero)
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, 2
Notice how 00 is inserted into the American wheel, creating an extra stopping point that increases the frequency of zero-type outcomes overall.
La Partage and En Prison: The European/French Rules That Lower the House Edge
If you want the most player-friendly roulette experience, look beyond “European” and specifically seek French roulette rules. French roulette typically uses a single-zero wheel and may include one of these rules on even-money bets (Red/Black, Odd/Even, High/Low):
La Partage (Split the Stake)
When you place an even-money bet and the ball lands on 0, you lose only half your stake (instead of the full amount).
- Effect on house edge for even-money bets: drops from about 2.70% to about 1.35%
- Effect on RTP for even-money bets: rises from about 97.30% to about 98.65%
En Prison (Imprisonment)
When you place an even-money bet and the ball lands on 0, your bet is “imprisoned” for the next spin. If your even-money bet wins on the next spin, you get your stake back (typically without profit). If it loses, you lose the stake.
In many standard implementations, En Prison produces the same effective house edge reduction on even-money bets as La Partage (about 1.35%), though the experience differs because the outcome is resolved over two spins rather than immediately via half-loss.
Why These Rules Are a Big Deal
Most roulette discussions focus on single zero vs double zero. That’s crucial, but La Partage and En Prison can make even-money betting significantly more efficient than standard European rules.
If your play style leans toward Red/Black or other even-money bets, choosing French roulette with one of these rules can be one of the simplest ways to improve your long-run expected return while keeping the game easy and fun.
Concrete RTP and House Edge Examples by Bet Type (What Really Changes)
On a given wheel type, standard payouts are structured so the house edge remains consistent across common bets. But the expected return differs by wheel because probabilities differ.
European vs American: Expected Loss Per $100 Wagered (Typical Standard Rules)
| Variant | House edge | RTP | Expected loss per $100 wagered |
|---|---|---|---|
| European (single zero) | 2.70% | 97.30% | About $2.70 |
| American (double zero) | 5.26% | 94.74% | About $5.26 |
| French (single zero + La Partage / En Prison) on even-money bets | 1.35% | 98.65% | About $1.35 (even-money bets only) |
That’s why many experienced players prioritize single-zero wheels, and even better, single-zero with La Partage or En Prison if they prefer outside bets.
American Roulette “Top Bet” to Watch: The 5-Number Bet (0, 00, 1, 2, 3)
American roulette often includes a special wager: the 5-number bet covering 0, 00, 1, 2, 3. A common payout is 6:1.
This bet is widely known for carrying a higher house edge than most other standard roulette bets. It’s a key reason many players prefer European or French roulette, where this specific wager typically doesn’t exist in the same form.
If your goal is to maximize value while keeping roulette simple, a practical tip is to focus on standard inside/outside bets and prioritize single-zero games rather than adding specialty bets with worse value.
Practical Tips: How to Choose the Best Roulette Variant for Better Value
Roulette is a game of chance, but you still have meaningful choices that can improve your overall experience and expected return; you can also play blackjack online stake for variety.
1) Choose European or French Roulette (Single Zero) Whenever Possible
- Single zero means a lower house edge (about 2.70% vs 5.26%).
- This can help your bankroll last longer and reduce the “tax” on each bet.
2) If You Like Even-Money Bets, Look for La Partage or En Prison
- These rules can reduce the effective house edge on even-money bets to about 1.35%.
- That’s a meaningful upgrade for Red/Black and similar strategies focused on steady hit frequency.
3) Match Bet Style to Your Preferred Volatility
- Lower volatility feel: outside bets (Red/Black, Odd/Even, High/Low), especially on French rules.
- Higher volatility feel: inside bets (straight, split, street) with bigger payouts but less frequent wins.
Both styles can be entertaining; the main “value” lever remains the wheel type and rules.
4) Keep Your Roulette Session Structured
- Set a budget for the session and stick to it.
- Consider flat betting (same stake each spin) if you want a more stable ride.
- Know that no betting pattern changes the wheel’s probabilities; your advantage comes from choosing the right variant and rules.
5) Use Wheel Sequence Knowledge for Neighbor Bets (If Offered)
If you play French-style roulette that allows neighbor bets, the wheel order becomes part of the entertainment and strategy selection. While it doesn’t change the house edge by itself, it can help you place bets more intentionally (for example, covering a number and its adjacent pockets on the wheel).
European vs American Roulette: Which One Is Better for Players?
If your goal is better value and a lower casino advantage, European roulette is typically the stronger pick because of its single-zero design and lower house edge.
If you can access French roulette with La Partage or En Prison, that can be even better for even-money bettors by lowering the effective house edge further.
American roulette still offers the same classic gameplay and excitement, but the presence of 00 means you’re paying a higher “cost of play” in expected terms. For many players, choosing a single-zero table is the easiest upgrade you can make without changing how you bet or how the game feels.
FAQ: Common Questions About European and American Roulette
Is European roulette always 2.70% house edge?
European roulette with a single-zero wheel and standard rules is about 2.70%. If the table applies La Partage or En Prison on even-money bets, the effective edge for those specific bets can drop to about 1.35%.
Do payout odds change between European and American roulette?
Standard payout odds (like 35:1 for a straight-up bet and 1:1 for Red/Black) are generally the same. The key difference is that the probabilities change because American roulette includes 00.
Does the wheel sequence affect my chances?
For standard bets, the pocket order around the wheel does not change the mathematical probability of outcomes on a fair wheel. However, the sequence matters for certain wheel-based bets (like neighbor bets) and for understanding how European and American wheels are physically constructed.
What’s the biggest practical takeaway?
Pick single-zero roulette when you can, and if you enjoy even-money bets, prioritize tables with La Partage or En Prison. This keeps the same roulette fun while reducing the casino advantage.
Bottom Line: The Best Roulette Choice for Lower House Edge
European roulette wins the value comparison because its 37-pocket, single-zero wheel produces a lower house edge (about 2.70%) than American roulette’s 38-pocket, double-zero wheel (about 5.26%). The payouts may look identical, but the added 00 shifts the probabilities, reduces expected return, and can make the game feel swingier over time.
For players who want the most benefit without complicating the game, the simplest recommendation is: choose European roulette, and when available, upgrade to French roulette with La Partage or En Prison for even-money bets. It’s the same classic roulette thrill, with better math working in your favor.
