American and European roulette share the same exciting objective: predict where the ball will land on a spinning wheel and place bets accordingly. Both versions offer a familiar range of wagers, from even-money bets on red or black to a 35-to-1 payout on a single number. That makes roulette easy to understand and enjoyable for players who appreciate a fast-moving game with clear betting options.
However, one small-looking difference has a major effect on the mathematics of the game. European roulette uses a wheel with one zero, while American roulette includes both a 0 and a 00. Because the standard payouts remain essentially the same, the additional double-zero pocket increases the casino advantage substantially.
For players comparing tables, the conclusion is straightforward: European roulette generally provides better odds and a higher theoretical return to player. Understanding why can help players make more informed choices before placing a wager.
The Key Difference: One Zero vs. Two Zeros
The most important distinction between the two roulette styles is the number of pockets on the wheel.
| Roulette version | Numbered pockets | Total pockets | Standard house edge |
|---|---|---|---|
| European roulette | 0 through 36 | 37 | 2.70% |
| American roulette | 0, 00, and 1 through 36 | 38 | 5.26% |
European roulette has 37 possible outcomes: the numbers 1 through 36 plus a single green zero. American roulette has 38 outcomes because it adds the double-zero pocket. On most standard bets, both 0 and 00 are losing outcomes for players who have wagered on red, black, odd, even, low, high, or most other number combinations.
That extra losing pocket may seem minor, but it almost doubles the casino’s mathematical advantage. The difference becomes especially meaningful over many spins, because each spin is an independent event and the built-in house edge applies repeatedly.
Why Identical Payouts Matter
American and European roulette typically use the same published payout schedule. A straight-up bet on one number pays 35 to 1 in both games. A red-or-black bet pays even money in both games. Split bets, street bets, corner bets, and dozens bets also follow the same general payout structure.
The issue is that American roulette gives players one additional way to lose without offering larger payouts to compensate. A single-number wager still pays 35 to 1, but its probability of winning changes:
- In European roulette, a straight-up number wins on 1 of 37 pockets.
- In American roulette, a straight-up number wins on 1 of 38 pockets.
The probability change is modest on one spin, but the payout does not improve. This is why the European wheel creates better value for nearly every standard roulette wager.
House Edge and Return to Player Explained
The house edge is the casino’s expected advantage over the long run. It is not a guarantee of what will happen in a short session. A player can win or lose on any individual spin. Instead, it describes the average percentage of total wagers the casino is expected to retain across a very large number of spins.
The return to player, often abbreviated as RTP, is the other side of that calculation. It represents the theoretical percentage of wagers returned to players over the long term.
| Roulette version | House edge | Theoretical RTP |
|---|---|---|
| European roulette with standard rules | 2.70% | 97.30% |
| American roulette with standard rules | 5.26% | 94.74% |
For every $100 wagered in total over a large sample of standard spins, European roulette has an expected theoretical loss of about $2.70, while American roulette has an expected theoretical loss of about $5.26. Actual short-term outcomes can vary widely, but the underlying comparison remains the same.
That stronger RTP is one of the biggest benefits of choosing a single-zero table. Players receive the same familiar game format, the same core betting options, and generally the same payouts, but with a lower mathematical cost of play.
European Roulette: A Better Foundation for Standard Bets
European roulette is often called single-zero roulette because it contains only one green zero. The wheel layout is arranged differently from an American wheel, but the practical advantage comes from the missing 00 pocket rather than from the order of the numbered pockets.
Most standard bets on a European table carry the same 2.70% house edge. These include:
- Even-money bets such as red or black, odd or even, and 1 to 18 or 19 to 36.
- Dozens and columns.
- Outside combination bets.
- Inside bets such as splits, streets, corners, and straight-up numbers.
This consistency makes European roulette particularly easy to evaluate. Players can choose bets based on their preferred balance of hit frequency and potential payout without facing a higher standard edge on most of the traditional wager types.
American Roulette: The Impact of the Double Zero
American roulette uses a double-zero wheel. The 00 pocket is not an extra player opportunity; it is an additional green outcome that usually causes outside bets and most other wagers to lose. Since standard payouts do not increase, the extra pocket raises the house edge to 5.26% on typical bets.
American roulette can still be entertaining for players who enjoy its familiar wheel layout or who have limited table choices. Yet when both versions are available under comparable conditions, European roulette is typically the more favorable option from a mathematical perspective.
The difference is particularly valuable for players who expect to make many wagers. A lower edge does not eliminate risk, but it reduces the expected cost of each dollar staked over time.
The American Five-Number Bet Has the Highest Standard Edge
One wager deserves special attention on the American roulette layout: the five-number bet, also known as the top line. This bet covers 0, 00, 1, 2, and 3.
It pays 6 to 1, but it covers five winning pockets on a 38-pocket wheel. Its house edge is approximately 7.89%, which is significantly higher than the 5.26% edge on most other American roulette bets.
| Bet type | Covered numbers | Typical payout | House edge |
|---|---|---|---|
| European standard bets | Varies by wager | Even money to 35 to 1 | 2.70% |
| American standard bets | Varies by wager | Even money to 35 to 1 | 5.26% |
| American five-number bet | 0, 00, 1, 2, 3 | 6 to 1 | 7.89% |
Because it has the highest standard house edge on an American table, the five-number bet is usually the least attractive roulette choice for players focused on value. It does not exist in European roulette because European wheels do not have a 00 pocket.
La Partage and En Prison: Valuable European Rule Variations
Some European and French roulette tables offer special rules for even-money bets. These bets include red or black, odd or even, and low or high. The rules apply when the ball lands on zero, and they can improve the player’s expected return.
La Partage
Under La Partage, when the ball lands on zero, a player with an even-money bet loses only half of that wager. For example, if a player bets $10 on red and zero appears, $5 is returned and $5 is lost.
This rule reduces the house edge on eligible even-money bets from 2.70% to approximately 1.35%. That is a meaningful improvement and one of the best standard roulette conditions available.
En Prison
Under En Prison, an even-money bet that loses to zero is not immediately lost. Instead, it remains “in prison” for the next spin. If the next spin wins for that wager, the original stake is returned without a profit. If it loses, the stake is lost. Specific handling of a second zero can vary by table rules.
Over the long term, En Prison also typically reduces the house edge on qualifying even-money bets to approximately 1.35%. Players should always check the table rules, because availability and exact procedures vary by casinos and online roulette platforms.
European Call Bets and Wheel Sectors
European roulette is also closely associated with call bets, sometimes called announced bets. Rather than simply covering adjacent numbers on the table layout, these wagers are based on sections of the physical wheel. Traditionally, a player can announce the bet to the dealer, who places the appropriate chips. Digital tables may present these options through a dedicated betting menu.
Common wheel-sector bets include:
- Voisins du Zéro: A group of 17 numbers surrounding zero on the wheel.
- Jeu Zéro: A smaller seven-number section around zero.
- Le Tiers du Cylindre: A 12-number sector on the opposite side of the wheel from zero.
- Orphelins: The “orphan” numbers not included in Voisins du Zéro or Le Tiers du Cylindre.
These bets add variety for players who enjoy the wheel’s traditional French-style structure. Their availability is not universal, especially online, and the exact chip placement may differ by table. They do not remove the house edge, but they offer another way to organize a betting approach around wheel sectors rather than the printed table layout.
Can Martingale or Fibonacci Systems Improve Roulette Odds?
Betting systems such as Martingale and Fibonacci can be used with either American or European roulette. They are popular because they provide a structured way to change bet sizes after wins or losses.
The Martingale system typically involves doubling an even-money wager after each loss, aiming to recover previous losses with one eventual win. The Fibonacci system raises stakes according to the Fibonacci sequence, usually after losses, using a slower progression than Martingale.
These systems may help some players organize a session, set betting rules, or choose a pace that feels comfortable. However, they do not change the house edge, predict future spins, or guarantee profit. Roulette spins are independent, and practical limits such as table maximums, bankroll size, and losing streaks remain important considerations.
Because the betting systems do not overcome the underlying mathematics, starting with the lower-edge version of the game is still beneficial. A European roulette table gives Martingale, Fibonacci, flat betting, and other approaches a better mathematical foundation than a standard American double-zero table.
How to Choose the Better Roulette Table
When comparing roulette options, a few quick checks can make a substantial difference:
- Look for a single-zero wheel. A European roulette wheel with 37 pockets is generally preferable to a 38-pocket American wheel.
- Check for La Partage or En Prison. These rules are especially valuable if you prefer red or black, odd or even, or low or high bets.
- Avoid the American five-number bet. Its 7.89% house edge makes it the least favorable standard wager on the table.
- Review the payout table and game rules. Reliable operators clearly display the wheel type, available wagers, and special-rule conditions.
- Set a budget before playing. A defined entertainment budget helps keep roulette enjoyable and prevents chasing losses.
American vs. European Roulette at a Glance
| Feature | European roulette | American roulette |
|---|---|---|
| Wheel pockets | 37 | 38 |
| Green pockets | 0 | 0 and 00 |
| Standard house edge | 2.70% | 5.26% |
| Standard theoretical RTP | 97.30% | 94.74% |
| Even-money edge with La Partage or En Prison | About 1.35%, where offered | Not standard |
| Five-number 0-00 bet | Not available | Available; 7.89% house edge |
| Traditional call bets | Often available, depending on the table | Less commonly offered |
Final Takeaway: European Roulette Delivers Better Value
American and European roulette offer the same core thrill: selecting numbers or groups of numbers and watching the ball decide the outcome. Both games provide a wide choice of wagers and identical headline payouts, including even-money bets and 35-to-1 straight-up bets.
Yet the single additional pocket on an American wheel has a clear and lasting effect. European roulette’s single-zero design lowers the standard house edge from 5.26% to 2.70% and raises the theoretical RTP from about 94.7% to 97.3%. When La Partage or En Prison is available, eligible even-money bets can improve further to an approximately 1.35% house edge.
For players who want to maximize the value of their roulette entertainment, European roulette is generally the stronger choice. It preserves the classic pace, betting flexibility, and excitement of roulette while offering more favorable long-term odds. Choosing a single-zero wheel, understanding the table rules, and playing within a planned budget creates a smarter starting point for every spin.
