Understanding the mathematical differences between European and American roulette can significantly impact your bankroll. We break down house edge, RTP percentages, and winning probabilities.
The core distinction between European and American roulette lies in their wheel configuration. European roulette features 37 pockets: numbers 1 through 36, plus a single green zero (0). American roulette adds an extra pocket—a double zero (00)—bringing the total to 38 pockets. This seemingly minor addition has profound implications for your winning chances.
On a European wheel, when you place a straight-up bet on any single number, you're competing against 36 other possibilities plus the zero. Your odds of winning are 1 in 37, or approximately 2.70%. On an American wheel, that same bet faces 37 other possibilities, giving you odds of 1 in 38, or roughly 2.63%. While this difference appears small on a single spin, it compounds significantly over hundreds or thousands of spins.
The visual layout also differs. American roulette wheels position the 00 directly opposite the 0, maintaining the wheel's balance. European wheels have a different number sequence, though both maintain the alternating red-black pattern and strategic distribution of odd-even and high-low numbers. Evolution Gaming's live roulette tables showcase both layouts beautifully, allowing you to see these differences in real-time HD streaming.
Beyond the wheel itself, the table layout reflects this difference. American roulette tables include an additional betting area for the 00, plus a unique five-number bet covering 0, 00, 1, 2, and 3—a bet that doesn't exist in European roulette and carries the worst odds on the table.
House edge represents the casino's built-in advantage, expressed as a percentage of each bet that the casino expects to keep over time. This is where the American Roulette vs Roulette comparison becomes critical for your bankroll.
European roulette maintains a house edge of 2.70% on all standard bets. This means that for every £100 you wager, the casino expects to keep £2.70 in the long run. American roulette, with its extra double zero pocket, increases the house edge to 5.26%—nearly double the European version. That's £5.26 retained by the house for every £100 wagered.
| Roulette Variant | Total Pockets | House Edge | RTP | £100 Expected Return |
|---|---|---|---|---|
| European Roulette | 37 | 2.70% | 97.30% | £97.30 |
| American Roulette | 38 | 5.26% | 94.74% | £94.74 |
| American (Five-Number Bet) | 38 | 7.89% | 92.11% | £92.11 |
The American Roulette RTP of 94.74% pales in comparison to European roulette's 97.30%. Over a typical gaming session, this difference becomes tangible. If you're playing with a £500 bankroll and making consistent bets, the European version will statistically preserve your funds longer, giving you more spins and entertainment value.
The five-number bet in American roulette (0-00-1-2-3) is particularly punishing, with a house edge of 7.89%. This bet pays 6:1 but should be avoided entirely, as it offers worse value than any other roulette bet across both variants.
While the house edge remains constant, your actual probability of winning varies depending on the bet type. Let's examine how the European vs American roulette comparison affects different betting strategies.
| Bet Type | European Odds | American Odds | Payout | European Win % | American Win % |
|---|---|---|---|---|---|
| Straight-Up (Single Number) | 36:1 against | 37:1 against | 35:1 | 2.70% | 2.63% |
| Split (Two Numbers) | 17.5:1 against | 18:1 against | 17:1 | 5.41% | 5.26% |
| Street (Three Numbers) | 11.33:1 against | 11.67:1 against | 11:1 | 8.11% | 7.89% |
| Corner (Four Numbers) | 8.25:1 against | 8.5:1 against | 8:1 | 10.81% | 10.53% |
| Red/Black, Odd/Even, High/Low | 1.06:1 against | 1.11:1 against | 1:1 | 48.65% | 47.37% |
| Dozen or Column | 2.08:1 against | 2.17:1 against | 2:1 | 32.43% | 31.58% |
The even-money bets (red/black, odd/even, high/low) demonstrate the impact clearly. On a European wheel, you'll win approximately 48.65% of the time—just under half. On an American wheel, this drops to 47.37%. That 1.28% difference translates to roughly 13 fewer wins per 1,000 spins.
Inside bets like straight-ups and splits show similar proportional differences. While the percentage changes appear small, they're consistent across all bet types, creating a cumulative disadvantage that grows with extended play. Pragmatic Play Live's roulette tables display these statistics clearly, helping you make informed decisions in real-time.
Some European roulette tables offer special rules that further reduce the house edge, making the European vs American roulette comparison even more favorable for the European variant.
La Partage Rule: Found on select European tables, this rule returns half your stake on even-money bets when the ball lands on zero. This effectively cuts the house edge to 1.35% on those specific bets—a significant improvement. Evolution Gaming's French Roulette tables typically feature this rule, making them particularly attractive for players focusing on outside bets.
En Prison Rule: Similar to La Partage, this rule "imprisons" your even-money bet when zero hits, giving it another chance on the next spin. If your bet wins on the subsequent spin, you recover your original stake without profit. If it loses, the casino takes it. This also reduces the house edge to 1.35% on even-money bets.
American roulette rarely offers comparable rules. The standard 5.26% house edge applies uniformly across most American tables at land-based and online casinos. Some Atlantic City casinos historically offered a surrender rule (similar to La Partage) on American roulette, but this is uncommon in the online space.
At Lukkly, our European roulette selection from providers like NetEnt and Authentic Gaming includes tables with favorable rules. The Roulette RTP can reach 98.65% on even-money bets when La Partage or En Prison rules apply, making these tables the mathematically optimal choice for players prioritizing bankroll longevity.
Speed roulette variants from Evolution Gaming maintain the same house edge percentages but compress the time between spins, increasing the number of bets per hour. This doesn't change the mathematical advantage but does affect variance and how quickly you'll experience the statistical expectations.
Theory meets practice when you consider how house edge affects your actual playing experience. Let's calculate the real-world impact on a typical gaming session.
Imagine you start with a £200 bankroll and make £5 bets on red/black. On a European wheel with a 2.70% house edge, your expected loss per bet is £0.135. On an American wheel with a 5.26% house edge, it's £0.263—nearly double.
If you make 100 bets during your session (roughly 90 minutes at a standard pace), here's what you can expect:
That's a £12.80 difference in a single session. Over a month of regular play, this gap widens considerably. The European version gives you nearly twice as many sessions before depleting the same bankroll.
Variance plays a role too. Short-term results can deviate significantly from expectations—you might win or lose far more than the house edge predicts in any given session. However, the house edge is relentless over time. The more you play, the closer your results will align with these mathematical expectations.
Professional players and advantage seekers universally avoid American roulette when European versions are available. The American Roulette review from any serious gambling analyst will emphasize this point: the extra double zero offers no benefit to the player and exists solely to increase the casino's profit margin.
At Lukkly, we're transparent about these differences. Our game selection includes both variants because some players prefer American roulette's traditional appeal or specific betting options. However, if your goal is maximizing your winning potential and extending your playing time, European roulette is the clear mathematical choice.
The data overwhelmingly supports European roulette as the superior choice from a player's perspective. The 2.70% house edge versus 5.26% isn't a minor difference—it's a fundamental mathematical advantage that compounds with every spin.
Here's my recommendation based on different player profiles:
For Casual Players: Stick exclusively to European roulette. Your entertainment budget will last longer, and you'll get more value from each session. The games play identically in terms of excitement and pace, so there's no reason to accept worse odds. Evolution Gaming's Immersive Roulette provides an exceptional European experience with multiple camera angles and slow-motion replays.
For Strategy-Focused Players: European roulette with La Partage or En Prison rules offers the absolute best odds. Focus on even-money bets to take advantage of the 1.35% house edge. NetEnt's French Roulette tables at Lukkly implement these rules perfectly, with clear indicators when your bet is imprisoned or eligible for partial return.
For High-Rollers: The house edge difference becomes even more significant with larger bets. A £100-per-spin player will lose an average of £2.70 per spin on European versus £5.26 on American. Over a typical high-roller session, this represents hundreds of pounds in additional expected losses. VIP tables from Pragmatic Play Live offer European roulette with elevated limits.
For Completionists: If you're determined to try American roulette for the experience, keep sessions short and avoid the five-number bet entirely. Consider it a novelty rather than your primary roulette choice.
The Roulette review consensus across gambling experts is unanimous: European roulette provides better value. Some players argue that American roulette offers more betting options or a more "authentic" Las Vegas experience, but these subjective preferences don't outweigh the mathematical disadvantage.
At Lukkly, our live casino lobby clearly labels each roulette variant, displays RTP percentages, and indicates which tables feature advantageous rules. We also offer free-play demos on select tables, allowing you to experience both variants without risking real money. This transparency helps you make informed choices aligned with your goals and playing style.
