For the seasoned gambler, the allure of the roulette wheel is timeless, a sophisticated dance between chance and strategic wagering.

The Core Distinction: Wheel Configuration and House Edge
At the heart of the American vs. European roulette debate lies the fundamental difference in their wheel configurations. This seemingly minor alteration has a profound impact on the house edge, directly influencing a player’s long-term prospects.
European Roulette: The Single Zero Advantage
The European roulette wheel features 37 pockets: numbers 1 through 36, alternating between red and black, and a single green pocket designated as ‘0’. This single zero is the sole source of the house’s advantage. When the ball lands on ‘0’, all bets on numbers, colors, odd/even, high/low, and columns/dozens are lost (unless specific rules like ‘En Prison’ or ‘La Partage’ are in play, which we will discuss later). The presence of only one zero pocket results in a significantly lower house edge.
- Total Pockets: 37
- House Edge (Standard Bets): 2.70%
This 2.70% house edge is derived from the fact that for every 37 possible outcomes, 36 of them result in a win or loss for the player based on their bet, while one outcome (the ‘0’) is a guaranteed loss for most standard bets. If you bet on a single number, your probability of winning is 1/37. The payout for a single number bet is 35:1, meaning you get your original bet back plus 35 units. If the true odds were 36:1, there would be no house edge. The difference between the 36:1 true odds and the 35:1 payout creates the house advantage.
American Roulette: The Double Zero Disadvantage
In contrast, the American roulette wheel features 38 pockets: numbers 1 through 36, a single ‘0’, and an additional ’00’ (double zero) pocket. Both the ‘0’ and ’00’ pockets are green and serve the same purpose: they are house pockets that cause most standard bets to lose. The addition of this extra pocket significantly increases the house’s advantage.
- Total Pockets: 38
- House Edge (Standard Bets): 5.26%
With 38 possible outcomes, the probability of winning a single number bet is 1/38. However, the payout remains 35:1. This discrepancy between the true odds (37:1 against winning) and the payout (35:1) results in a much higher house edge. For every 38 spins, the house expects to win two units more than it would if the payouts were fair (36:1). This nearly doubles the house advantage compared to European roulette, making it a less favorable option for the discerning player.
Impact on Specific Bets and Payouts
While the house edge is a critical overarching metric, it’s also important to understand how it manifests across different types of bets.
Standard Outside Bets (Red/Black, Odd/Even, High/Low)
These bets pay 1:1. In European roulette, you have 18 winning outcomes out of 37, giving you an 18/37 (48.65%) chance of winning. In American roulette, you have 18 winning outcomes out of 38, resulting in an 18/38 (47.37%) chance of winning. The difference might seem small per spin, but over hundreds or thousands of spins, it significantly impacts the expected return.
Standard Inside Bets (Single Number, Split, Street, Corner, Line)
The payouts for these bets are identical in both versions (e.g., 35:1 for a single number). However, the probability of hitting them is lower in American roulette due to the extra ’00’ pocket. For instance, a single number bet has a 1/37 chance of winning in European roulette vs. a 1/38 chance in American roulette.
The “Five-Number Bet” (American Roulette Only)
American roulette offers a unique bet known as the “Five-Number Bet” or “Basket Bet,” covering 0, 00, 1, 2, and 3. This bet pays 6:1. While it might seem appealing due to covering five numbers, it carries the worst house edge of any bet in roulette, standing at a staggering 7.89%. Experienced players should unequivocally avoid this bet.
Special Rules: En Prison and La Partage
Some European roulette tables, particularly in land-based casinos, offer special rules that further reduce the house edge on even-money bets. These rules are rarely, if ever, found in American roulette.
La Partage
Meaning “the sharing” in French, this rule applies when the ball lands on ‘0’ and you have placed an even-money bet (Red/Black, Odd/Even, High/Low). Instead of losing your entire bet, you lose only half of it. This effectively halves the house edge on even-money bets from 2.70% to 1.35%, making European roulette an even more attractive proposition for these specific wagers.
En Prison
Meaning “in prison,” this rule is similar to La Partage but offers a different mechanism. When the ball lands on ‘0’ and you have an even-money bet, your bet is “imprisoned” for the next spin. If your bet wins on the subsequent spin, you get your original stake back (without any winnings). If it loses, you lose the entire bet. If the ‘0’ appears again, the bet can either remain imprisoned or be lost, depending on the specific casino’s rules. Like La Partage, En Prison reduces the house edge on even-money bets to 1.35%.
These rules are a significant advantage for players, transforming European roulette from a game with a moderate house edge into one of the most player-friendly casino games for even-money bets.
Strategic Implications for Experienced Gamblers
For the experienced gambler, the choice between American and European roulette is clear from a statistical standpoint.
- Prioritize European Roulette: Always opt for European roulette whenever available. The significantly lower house edge (2.70% vs. 5.26%) means you will lose less money on average over the long run. If ‘La Partage’ or ‘En Prison’ rules are offered, the advantage becomes even more pronounced for even-money bets, reducing the house edge to a mere 1.35%.
- Avoid the Five-Number Bet: In American roulette, the “Five-Number Bet” is a statistical trap with an exceptionally high house edge. A knowledgeable player will never place this wager.
- Bankroll Management: While the house edge is lower in European roulette, it is still a game of chance. Effective bankroll management remains crucial. The reduced house edge simply means your bankroll will likely last longer, allowing for extended play and more opportunities.
- Understanding Variance: Even with a lower house edge, short-term results can be highly variable. A streak of bad luck can occur even in the most favorable games. Experienced players understand that the house edge plays out over thousands of spins, not just a handful.
Conclusion: The Definitive Choice for the Discerning Player
In the perennial debate between American and European roulette, the statistical evidence overwhelmingly favors the latter. The presence of a single zero pocket in European roulette halves the house edge compared to its double-zero American counterpart, making it a demonstrably more advantageous game for players. When special rules like ‘La Partage’ or ‘En Prison’ are applied, the European variant becomes one of the most player-friendly games in the casino.
For the experienced gambler, who understands that every percentage point of house edge translates into long-term financial impact, the choice is not merely a preference but a strategic imperative. To maximize one’s chances and extend playtime, consistently selecting European roulette over American roulette is the prudent decision. This informed approach, coupled with sound bankroll management and a deep understanding of the game’s mechanics, is the hallmark of a truly seasoned player.
