European vs American vs French Roulette: Complete Comparison
Learn the basics and become a pro
Not all roulette wheels are created equal. The variant you play directly impacts your odds, your expected losses, and the effectiveness of every strategy you use. Understanding the differences between European, American, and French roulette is the single most important decision you make before placing a bet.
Why the Variant Matters for Strategy
Every roulette strategy is built on probabilities. When you change the number of pockets on the wheel, you change every probability in the game. A strategy optimized for European roulette performs measurably worse on an American wheel, and measurably better on a French table with La Partage.
The difference is not trivial. Over 1,000 bets of $10 each on even-money outcomes, the expected loss varies dramatically:
- French roulette (La Partage): -$135 expected loss
- European roulette: -$270 expected loss
- American roulette: -$526 expected loss
That is a nearly 4x difference between the best and worst variants. Choosing the right wheel is the highest-impact, zero-effort optimization available to any roulette player.

European Roulette
European roulette is the standard variant used in most casinos worldwide and the baseline for virtually all strategy discussion. It features a single green zero pocket alongside numbers 1 through 36, for a total of 37 pockets.
Key Characteristics
- Pockets: 37 (numbers 0-36)
- Zero pockets: 1 (single zero: 0)
- House edge: 2.70% on all bets
- Even-money win probability: 18/37 = 48.65%
- Straight-up payout: 35:1
Even-Money Bet: $10 on Red
Covers 18 red numbers (48.65% win rate on European). Payout: 1:1
How the House Edge Works
The house edge comes entirely from the zero pocket. When you bet on Red, there are 18 red numbers, 18 black numbers, and 1 green zero. You win on 18 out of 37 outcomes but are paid as if there were only 36 numbers (even-money pays 1:1, straight-up pays 35:1). The single zero is the casino's built-in profit margin.
Mathematically: (37 - 36) / 37 = 1/37 = 2.70%.
Number Layout
The European wheel arranges numbers in a specific sequence designed to alternate red/black, high/low, and odd/even as evenly as possible. The sequence clockwise from zero is: 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.
This wheel layout matters for neighbor bets and section bets (Voisins du Zero, Tiers du Cylindre, Orphelins), which are based on physical wheel position rather than the table grid.

American Roulette
American roulette adds a second green pocket: the double zero (00). This seemingly small change has an outsized impact on your odds. With 38 pockets instead of 37, every bet on the table becomes worse for the player while payouts remain identical.
Key Characteristics
- Pockets: 38 (numbers 0, 00, 1-36)
- Zero pockets: 2 (single zero: 0, double zero: 00)
- House edge: 5.26% on all bets (except one)
- Even-money win probability: 18/38 = 47.37%
- Straight-up payout: 35:1 (same as European, worse odds)
Why the Double Zero Hurts
The payouts on American roulette are calculated as if there were 36 numbers, just like European. But there are 38 pockets. The casino keeps the difference. Two zero pockets instead of one means the casino's margin nearly doubles.
Mathematically: (38 - 36) / 38 = 2/38 = 5.26%.
To put this in perspective, the American house edge is 95% higher than the European house edge. For every $100 you wager, you expect to lose $5.26 on American versus $2.70 on European. Over hundreds of spins, this compounds into a significant difference.
The Five-Number Bet: The Worst Bet in Roulette
American roulette has one unique bet: the five-number bet (also called the "top line" or "basket bet") covering 0, 00, 1, 2, and 3. This bet pays 6:1 but has a house edge of 7.89% - the single worst bet available on any standard roulette table. Avoid it unconditionally.
Number Layout
The American wheel uses a completely different number sequence from the European wheel. Numbers are arranged to place consecutive numbers directly opposite each other. The 0 and 00 are positioned on opposite sides of the wheel. This layout has no impact on inside or outside bet probabilities, but it does affect any strategy based on wheel sectors.
French Roulette
French roulette uses the exact same wheel as European roulette: 37 pockets with a single zero. The difference is at the table, not the wheel. French roulette features a different table layout with French betting names and, most importantly, two special rules that further reduce the house edge on even-money bets.
Key Characteristics
- Pockets: 37 (numbers 0-36, same wheel as European)
- Zero pockets: 1 (single zero: 0)
- House edge (standard bets): 2.70%
- House edge (even-money bets with La Partage/En Prison): 1.35%
- Even-money win probability: 18/37 = 48.65%
The La Partage Rule
La Partage (French for "the sharing") activates when you place an even-money bet (Red/Black, Odd/Even, High/Low) and the ball lands on zero. Instead of losing your entire bet, the casino returns half your stake.
Example: You bet $20 on Red. The ball lands on 0 (green). On a European table, you lose $20. On a French table with La Partage, you get $10 back. Your loss is halved.
This single rule cuts the house edge on even-money bets in half: from 2.70% down to 1.35%. This is the lowest house edge available on any standard roulette table in the world.
The En Prison Rule
En Prison (French for "in prison") is an alternative to La Partage. When zero hits on an even-money bet, your wager is placed "in prison" - it stays on the table for one more spin.
- Zero hits: Your even-money bet is marked "en prison" (locked in place)
- Next spin wins: You get your original bet back (no profit, just your stake returned)
- Next spin loses: You forfeit the entire bet
- Zero hits again: Rules vary by casino (some return half, some keep the bet in prison)
The mathematical effect is identical to La Partage: the house edge on even-money bets drops to 1.35%. The difference is psychological and practical - En Prison gives you a chance to recover the full bet rather than accepting half back immediately.
French Table Layout
The French table uses French labels for bets: Manque (1-18), Passe (19-36), Pair (Even), Impair (Odd), Rouge (Red), Noir (Black). The layout places even-money bets on both sides of the number grid rather than one end. While this is purely cosmetic, it signals that the table likely offers La Partage or En Prison rules.
La Partage in Action
Place an even-money bet (Red, Black, Odd, Even, High, or Low) and spin. When zero hits, La Partage returns half your stake automatically. Compare that to European roulette where you lose the full bet on zero.
La Partage Example: $1 on Red, ball lands on 0
European: lose $1.00. French (La Partage): lose $0.50 - half returned. This halves the house edge on even-money bets from 2.70% to 1.35%.

Which Variant Should You Play?
For serious strategy play, the answer is straightforward: French roulette with La Partage if you are using even-money bets (Red/Black, Odd/Even, High/Low), and European roulette for everything else. American roulette should be avoided entirely when a European or French alternative exists.
Choose French Roulette When
- Your strategy uses even-money bets: The 1.35% house edge is unmatched
- You use progressions like Martingale or D'Alembert: Lower house edge means slower bankroll erosion and longer survival during losing streaks
- The table genuinely offers La Partage or En Prison: Verify before sitting down
Choose European Roulette When
- Your strategy uses inside bets: Straight-ups, splits, corners, streets - La Partage does not apply to these, so European and French are identical
- French tables are unavailable: European is the next best option at 2.70%
- You want maximum game availability: European tables are the most common worldwide
Inside Bet Strategy Example
Straight on 17 + Corner on 16-17-19-20 + Split on 17-18. La Partage does not apply to inside bets.
Avoid American Roulette When
- You are using any betting system: The 5.26% edge degrades every strategy faster
- You care about expected value: You lose nearly twice as much per dollar wagered
- A European or French table is available: There is no strategic advantage to American roulette
The Only Time American Roulette Is Acceptable
If American roulette is the only variant available at your casino or on your platform, it is still playable - just understand that your expected losses are higher. In land-based casinos in the United States, American roulette tables are sometimes the only option. In that case, stick to outside bets and keep sessions short.
How Roulette Variants Affect Progressions
The roulette variant you play directly impacts how well any progression system performs. Here is how the house edge difference plays out across popular progressions:
Martingale on Different Variants
The Martingale doubles your bet after each loss on even-money bets. With a $5 base bet and a 7-loss limit, the probability of busting differs by variant:
- French (La Partage): ~0.74% chance of 7 consecutive losses per sequence
- European: ~0.87% chance of 7 consecutive losses per sequence
- American: ~1.04% chance of 7 consecutive losses per sequence
While the per-sequence difference looks small, over hundreds of sequences in a session, the cumulative effect is substantial. American roulette gives you roughly 20% more bust sequences than European over the same number of spins.
D'Alembert and Fibonacci
These slower progressions are even more sensitive to house edge differences because they require more spins to complete a cycle. More spins means more exposure to the house edge. A D'Alembert progression that averages 20 spins per cycle loses roughly twice as much per cycle on American versus European.
Inside Bet Strategies
Strategies that use straight-up bets, splits, or corners do not benefit from La Partage (it only applies to even-money bets). For these strategies, European and French roulette are mathematically identical at 2.70%. American roulette remains worse at 5.26%.
How This Works in SpinStrategy
All SpinStrategy strategies and progressions are calculated using European roulette odds (single zero, 37 pockets, 2.70% house edge). This is the industry standard and ensures your strategies are optimized for the most commonly available variant.
What This Means for You
- European tables: SpinStrategy odds match exactly - use strategies as configured
- French tables (La Partage): Your even-money strategies perform better than projected - the lower house edge works in your favor
- American tables: Your strategies perform worse than projected - expect higher variance and faster bankroll erosion
Adjusting for American Roulette
If you must play on an American table, consider these adjustments in SpinStrategy:
- Lower your base unit: Compensate for faster bankroll erosion
- Tighten loss limits: Use triggers to close sessions earlier
- Reduce session length: Fewer spins means less exposure to the higher house edge
- Use Conservative Recovery: Protect peak profits during drawdowns, which are more frequent on American wheels
Common Myths About Roulette Variants
Myth: "American roulette has better payouts"
False. Payouts are identical across all three variants. A straight-up bet pays 35:1 on European, American, and French roulette. The difference is in the odds of winning, not the payouts. American roulette gives you worse odds for the same payouts.
Myth: "The wheel sequence affects my odds"
False for table bets. Whether you bet on Red, a Dozen, or a specific number, the physical arrangement of numbers on the wheel does not change your probability. The wheel sequence only matters for neighbor bets and section bets, which are based on physical proximity on the wheel.
Myth: "Online roulette has different odds than live"
False for regulated casinos. Licensed online roulette games use certified random number generators (RNGs) or live dealer wheels that produce the same mathematical odds as any physical casino. The variant (European, American, French) determines the odds, not the platform.
Myth: "La Partage only helps on long sessions"
False. La Partage helps from the very first spin. Every time zero hits on an even-money bet, you save half your stake. Whether that happens on spin 5 or spin 500, the savings are real and immediate.
Frequently Asked Questions
What is the house edge for each roulette variant?
European roulette has a 2.70% house edge. American roulette has a 5.26% house edge due to the extra double-zero pocket. French roulette has a 2.70% standard house edge, but the La Partage and En Prison rules reduce it to 1.35% on even-money bets.
What is the La Partage rule in French roulette?
La Partage (meaning "the sharing") returns half your even-money bet when the ball lands on zero. If you bet $10 on Red and zero hits, you get $5 back instead of losing the full $10. This cuts the house edge on even-money bets from 2.70% to 1.35%.
What is the En Prison rule in French roulette?
En Prison (meaning "in prison") holds your even-money bet on the table when zero hits. On the next spin, if your bet wins, you get your original stake back (no profit). If it loses, you forfeit the bet. The mathematical effect is identical to La Partage: 1.35% house edge on even-money bets.
Why is American roulette worse for players?
American roulette adds a double-zero (00) pocket, increasing total pockets from 37 to 38 while payouts remain the same. This nearly doubles the house edge from 2.70% to 5.26%. Over 1,000 bets of $10 each, you'd expect to lose $270 on European but $526 on American.
Which roulette variant should I use for strategy play?
European or French roulette. French roulette with La Partage drops the house edge to 1.35% on even-money bets, making it the best option for progressions like Martingale, D'Alembert, and Paroli. Avoid American roulette for serious strategy play.
Conclusion
The roulette variant you choose is the foundation of every strategy decision that follows. French roulette with La Partage offers the lowest house edge in the game at 1.35% on even-money bets. European roulette is the universal standard at 2.70%. American roulette's 5.26% edge makes it the worst choice for any serious player.
