Roulette feels simple on the surface: pick a number or a color, watch the wheel spin, and see where the ball lands. But the version you play matters a lot more than many players realize. The key difference between European roulette and American roulette is the wheel itself, and that one design choice changes the long-term cost of every bet you place.
If your goal is to get more entertainment time for your bankroll (and the best mathematical value available in standard roulette), European-style games are usually the smarter pick. In many casinos and online lobbies, you can even do better than standard European roulette by choosing French roulette rules like La Partage or en prison, which can reduce the casino advantage even further on specific bets.
This guide breaks down the exact differences, the real-world impact on your expected losses, and practical advice for choosing the best roulette table or online variant. For further reading on regional differences and history, read here.
The Core Difference: One Extra Pocket Changes Everything
Both European and American roulette use the same basic idea: a wheel with numbered pockets and a layout (the felt) where you place bets. The big difference is how many pockets are on the wheel.
- European roulette wheel: 37 pockets (numbers 1 to 36, plus a single 0).
- French roulette wheel: Typically also 37 pockets (1 to 36, plus a single 0), but may include special rules on even-money bets.
- American roulette wheel: 38 pockets (1 to 36, plus 0 and 00).
That additional 00 pocket is not just a cosmetic change. It increases the probability that the ball lands on a green pocket, which is what drives the casino advantage higher.
European vs American Roulette Odds: House Edge Explained (With Real Numbers)
Roulette payouts for standard bets are designed around a 36-to-1 structure. For example, a straight-up bet on a single number pays 35 to 1 (you win 35 units plus your original 1-unit stake back). That payout would be “fair” if there were only 36 possible outcomes. But the wheel has either 37 or 38 outcomes, which is where the house edge comes from.
House edge on a European (single-zero) wheel
On a European wheel, there are 37 equally likely outcomes. The casino advantage is essentially the extra pocket beyond 36:
European house edge = 1 / 37 ≈ 2.70%
More precisely, 1 / 37 is about 2.7027%.
House edge on an American (double-zero) wheel
On an American wheel, there are 38 equally likely outcomes:
American house edge = 2 / 38 ≈ 5.26%
More precisely, 2 / 38 is about 5.2632%.
Why this matters in practice (expected cost)
House edge is a long-term average, not a guarantee for any single session. Still, it’s a powerful way to compare value because it tells you the average amount you “pay” to play over time.
Here’s a simple way to think about it:
- If you wager 100 units in total on European roulette, your expected loss is about 2.70 units.
- If you wager 100 units in total on American roulette, your expected loss is about 5.26 units.
That difference compounds quickly. Over many spins, choosing a single-zero wheel can translate to noticeably more playtime for the same bankroll.
Quick Comparison Table: European vs American vs French Roulette
| Variant | Wheel Pockets | Green Pockets | Typical House Edge | Best For |
|---|---|---|---|---|
| European roulette | 37 | 0 | ~ 2.70% | Better odds with familiar rules |
| American roulette | 38 | 0 and 00 | ~ 5.26% | Players who prefer the classic U.S. casino standard |
| French roulette (with special rules) | 37 | 0 | ~ 2.70% normally; ~ 1.35% on even-money bets with La Partage or en prison | Value-focused players, especially on red/black and even/odd |
French Roulette’s Big Advantage: La Partage and en prison
French roulette often uses the same single-zero wheel as European roulette, but it may include one of two rules that improve player value on even-money bets (like red/black, odd/even, and 1 to 18 / 19 to 36).
What is La Partage?
La Partage (French for “the sharing”) typically means that if you place an even-money bet and the ball lands on 0, you lose only half your stake instead of the full amount.
This cuts the house edge on even-money bets in half:
Even-money house edge with La Partage = 1 / 74 ≈ 1.35%
What is en prison?
En prison (“in prison”) is similar in effect. When the ball lands on 0 and you have an even-money bet, your stake is “imprisoned” for the next spin. If your bet wins on the next spin, you get your stake back (often without profit). If it loses, you lose the stake.
In typical single-zero French roulette, en prison produces the same long-run house edge on even-money bets as La Partage, which is about 1.35%.
Why these rules are a big deal for common strategies
Many players gravitate toward even-money bets because they feel steady and easy to follow. If you’re in that camp, choosing a French roulette table with La Partage or en prison can be one of the most meaningful improvements you can make without changing how you like to play.
Do Payouts and Bets Change Between European and American Roulette?
For standard roulette, the payouts and the basic bet types are essentially the same across European, French, and American roulette. That’s why the wheel design (single zero vs double zero) is so important: you’re usually getting the same payout schedule, but facing different odds.
Common bets you’ll see in both versions
- Straight up: one number, pays 35 to 1
- Split: two adjacent numbers, pays 17 to 1
- Street: three numbers in a row, pays 11 to 1
- Corner: four numbers, pays 8 to 1
- Six line: six numbers, pays 5 to 1
- Dozens: 1 to 12, 13 to 24, 25 to 36, pays 2 to 1
- Columns: one vertical column, pays 2 to 1
- Even-money bets: red/black, odd/even, 1 to 18 / 19 to 36, pays 1 to 1
Because payouts generally do not improve to compensate for the extra 00 in American roulette, the American wheel is the higher-cost option over time.
Layout and Wheel Order: More Differences Than Pocket Count
The number of pockets drives the math, but there are also practical differences that can affect how the game feels.
Wheel number sequence differs
European and American roulette wheels use different number orders (the sequence of numbers around the wheel). The American wheel also places 0 and 00 on the wheel, typically adjacent near the top of the wheel layout.
For most players, the sequence difference doesn’t change expected value (each pocket is still equally likely in an ideal wheel). But it can affect:
- Visual pattern preferences: Some players like how certain numbers sit relative to each other.
- Neighbor betting style: If you enjoy betting “neighbors” around a chosen number, the wheel order becomes part of your routine.
Variance feels different when the edge changes
Roulette is a high-variance game compared with many other casino classics, because outcomes are discrete and streaks are common. When you increase the house edge (as in American roulette), you’re increasing the rate at which the game “taxes” your betting volume. That can make bankroll swings feel harsher over extended play, even though short sessions can still go either way.
Why Did American Casinos Add the Double Zero?
The short, practical answer is that the double zero increases the casino’s advantage. Historically, roulette evolved in Europe with a single zero format. When roulette expanded and became widely offered in the United States, adding the 00 was a straightforward way for operators to boost profitability while keeping the game familiar and the payout table unchanged.
That design choice stuck, and American roulette became the standard wheel in many U.S. land-based casinos for decades. Today, with online casinos and more global competition, players can often choose between multiple roulette variants in the same lobby, making it easier than ever to opt for the better-value wheel.
Common Variants You’ll See in Land-Based Casinos and Online
Knowing the names helps you quickly filter for value.
Single-zero options (usually better value)
- European roulette: Single-zero, straightforward rules.
- French roulette: Single-zero, sometimes with La Partage or en prison.
- Single-zero roulette: Often used as a plain-language label online.
Double-zero options (higher house edge)
- American roulette: Includes 0 and 00.
- Double-zero roulette: Another common label, especially online.
Heads-up on “special” roulette games
Both online and in casinos, you may also see variants marketed for excitement, such as side bets, bonus multipliers, or novelty rules. These can be entertaining, but they often come with a higher house edge than classic single-zero roulette. If your priority is value, focus first on single-zero and favorable rules, then decide whether you want extra features.
Practical Player Advice: How to Choose the Best Roulette Table
If you want the best odds with minimal effort, you don’t need a complicated system. You need a smart selection process.
1) Choose a single-zero wheel whenever possible
This one move can nearly halve the house edge compared with American roulette. If you can pick between European and American, the value-focused choice is usually:
European (0) over American (0 and 00)
2) Look for La Partage or en prison if you like even-money bets
If you mainly bet red/black or odd/even, French rules can be a strong upgrade. Your edge as a player doesn’t become positive, but your expected cost drops meaningfully:
- Standard European even-money bets:~ 2.70% edge to the house
- French with La Partage or en prison (even-money bets):~ 1.35% edge to the house
3) Confirm the rules before you sit down (or click “Play”)
Especially online, the game title alone is not always enough. Check:
- Is the wheel single-zero or double-zero?
- Are La Partage or en prison offered, and on which bets?
- Are there optional side bets that you can ignore if you want to keep the game simple?
4) Match table limits to your bankroll for longer playtime
Choosing the best odds is step one. Step two is making sure volatility doesn’t end your session early. A practical guideline many players use is to bring enough for at least:
- 50 to 100 minimum bets for a casual session, or
- 100 to 200 minimum bets if you want more cushion against swings
This doesn’t change the math of the game, but it can dramatically improve your experience by reducing the chance that a short cold streak ends your session immediately.
5) Keep betting simple if your goal is steady entertainment
Roulette is designed so that, on a given wheel, the house edge is broadly consistent across standard bets. So “best” often means best for your style:
- If you like frequent small wins, consider outside bets (and prioritize French rules if available).
- If you enjoy chasing big hits, straight-up bets deliver excitement, but swings will be larger.
The big value lever remains the wheel and rules, not a specific pattern of bets.
A Concrete Example: How Single-Zero Can Stretch Your Bankroll
Imagine two players each wager a total of 1,000 units over the course of an evening. One plays European roulette and the other plays American roulette, using similar bet types.
- European expected loss: 1,000 × 2.70% ≈27 units
- American expected loss: 1,000 × 5.26% ≈52.6 units
That’s an expected difference of about 25.6 units over the same total wagering. In real sessions, luck dominates short-term results, but over repeated play this is exactly why many experienced players actively seek out single-zero tables.
European vs American Roulette: Which One Should You Play?
If you’re choosing based on odds and value, the decision is straightforward.
Choose European roulette if you want:
- Better standard odds thanks to the single zero
- Lower expected losses over time
- A widely available format in many international casinos and online platforms
Choose French roulette if you want:
- Everything you like about European roulette, plus
- The potential benefit of La Partage or en prison on even-money bets
Choose American roulette if you:
- Prefer the classic U.S. wheel experience, or
- Only have double-zero tables available
Even then, if both are available side-by-side, choosing single-zero is a simple upgrade that costs you nothing and improves your long-term value.
FAQ: Quick Answers to Common Questions
Is European roulette “easier to win” than American roulette?
In the long run, European roulette is better value because the house edge is lower. That doesn’t guarantee wins in a single session, but it improves your expected result over time.
Do strategies work better on European roulette?
No betting strategy can remove the built-in house edge of roulette. However, a strategy played on a lower-edge game (European or French) will generally cost less over time than the same strategy played on a higher-edge game (American).
Does La Partage apply to all bets?
Typically, La Partage applies to even-money outside bets (red/black, odd/even, and high/low). It usually does not apply to inside bets like straight-up numbers.
What is the single most important thing to check before playing?
Check the wheel: single zero (0) is usually better than double zero (0 and 00). Then look for La Partage or en prison if you plan to bet even-money outcomes.
The Takeaway: Pick the Wheel That Works in Your Favor
Roulette is one of the easiest casino games to understand, and it’s also one of the easiest to optimize with a simple choice: play single-zero roulette when you can. European roulette lowers the house edge to about 2.70% compared with roughly 5.26% in American roulette, and French rules like La Partage or en prison can reduce the edge to around 1.35% on even-money bets.
If you like roulette for its pace, suspense, and classic casino feel, choosing the better variant is a win-win: you keep the same core game, while giving yourself more value, more playtime, and a smoother path to enjoying the session.
