American and European roulette have the same exciting core objective: predict where the ball will land on a spinning wheel and place a wager on a number, color, range, or combination of numbers. Both games use familiar roulette bets and offer the same standard payout range, from 1:1 on even-money wagers to 35:1 on a single-number straight-up bet.
The meaningful difference is found on the wheel itself. European roulette has 37 pockets, while American roulette has 38. That one additional pocket, the double zero, has a major effect on probabilities, return to player, and the long-term cost of play. For players who value stronger mathematical odds, European roulette is generally the more favorable option.
This guide, informed by washingtonbeerblog.com, explains how the two variants work, compares their house edges and RTP figures, covers special European roulette rules, and highlights the bets that can help players make more informed table choices.
American Roulette vs European Roulette at a Glance
| Feature | European Roulette | American Roulette |
|---|---|---|
| Wheel pockets | 37 pockets | 38 pockets |
| Number range | 0 to 36 | 0, 00, and 1 to 36 |
| Zeros | One zero | Zero and double zero |
| Standard house edge | 2.70% | 5.26% |
| Standard RTP | Approximately 97.30% | Approximately 94.74% |
| La Partage and En Prison | May be available | Not standard |
| Call bets | Often available | Generally not offered as traditional call bets |
| Five-number bet | Not available | Available, with a 7.89% house edge |
| Standard payout range | 1:1 to 35:1 | 1:1 to 35:1 |
The table makes the central comparison clear: the payout schedule is largely the same, but European roulette spreads those payouts across fewer possible outcomes. As a result, European roulette offers a higher theoretical return over many spins.
The Wheel Layout Creates the Biggest Difference
European roulette: 37 pockets
A European roulette wheel contains the numbers 1 through 36 plus a single green zero pocket. This creates 37 possible landing positions for the ball.
Because there is only one zero, every standard wager has fewer ways to lose to a green pocket than it would on a double-zero wheel. This is the reason the game carries its familiar 2.70% house edge.
American roulette: 38 pockets
An American roulette wheel includes the numbers 1 through 36, a green 0 pocket, and a green 00 pocket. The 00 is not just an extra visual feature. It is an additional outcome that causes most standard bets to lose.
With 38 possible outcomes rather than 37, the house advantage on standard American roulette bets rises to 5.26%. That is nearly twice the house edge of standard European roulette.
Why one extra pocket matters so much
At first glance, adding one pocket may seem like a small change. However, roulette pays the same advertised rewards in both versions. A straight-up number bet still pays 35:1, and a red or black bet still pays 1:1. The extra double-zero outcome reduces the chance of winning without increasing the payout.
That combination is what makes European roulette especially appealing to players who want to maximize value from the same style of game.
House Edge and RTP Explained
The house edge is the casino's built-in mathematical advantage over the long term. RTP, or return to player, expresses the opposite side of that relationship: the theoretical percentage of total stakes returned to players across a very large number of bets.
These figures do not predict what will happen during one session. Any individual spin can win or lose. Instead, they are useful for comparing the long-term value of similar games.
European roulette odds
Standard European roulette has a house edge of 2.70% on its regular bets. Its theoretical RTP is therefore approximately 97.30%.
For example, over a very large volume of wagers, a 2.70% house edge means that the expected casino advantage is $2.70 for every $100 wagered. Actual short-term results can vary substantially, but the mathematical framework remains the same.
American roulette odds
Standard American roulette has a house edge of 5.26% and an RTP of approximately 94.74%. In long-run terms, this represents an expected casino advantage of $5.26 per $100 wagered.
For players deciding between otherwise similar tables, European roulette provides a notably stronger return profile. The gameplay remains recognizable, the standard wagers remain available, and the theoretical cost of play is lower.
Standard Roulette Bets and Payouts
American and European roulette both feature a broad range of inside and outside bets. The probability changes between versions because of the extra 00 pocket, but the usual payout structure is the same.
| Bet Type | What It Covers | Standard Payout |
|---|---|---|
| Straight-up | One number | 35:1 |
| Split | Two adjacent numbers | 17:1 |
| Street | Three numbers in a row | 11:1 |
| Corner | Four numbers | 8:1 |
| Six line | Six numbers across two rows | 5:1 |
| Dozen | 12 numbers | 2:1 |
| Column | 12 numbers | 2:1 |
| Red or black | One color, excluding green zero pockets | 1:1 |
| Odd or even | Odd or even numbers, excluding green zero pockets | 1:1 |
| Low or high | 1 to 18 or 19 to 36 | 1:1 |
Inside bets provide higher potential payouts but cover fewer numbers. Outside bets cover more outcomes and produce more frequent wins, although the wins are smaller. This variety gives roulette its flexibility: players can choose a simple red or black bet, target a favorite number, or combine several wagers to create their preferred level of coverage.
European Roulette Special Rules: La Partage and En Prison
Some European roulette tables offer rules that improve the value of even-money bets. These rules generally apply to red or black, odd or even, and low or high wagers when the ball lands on zero.
La Partage
Under La Partage, an even-money bet loses only half its stake when the ball lands on zero. If a player wagers $10 on black and zero appears, $5 is returned and $5 is lost.
This rule cuts the house edge on qualifying even-money bets from 2.70% to approximately 1.35%. That is one of the best mainstream roulette value propositions available.
En Prison
Under En Prison, an even-money bet is not immediately lost when zero appears. Instead, the wager remains on the table for the next spin. If the bet wins on that next spin, the original stake is returned. If it loses, the stake is lost.
Over the long run, En Prison also reduces the house edge on qualifying even-money wagers to approximately 1.35%. The mechanics differ from La Partage, but the mathematical benefit is similar.
These rules are not automatically available at every European roulette table. Players should always check the table rules before placing a wager, especially in online games where rule variations may be shown in the game information panel.
Call Bets and Racetrack Bets in European Roulette
European roulette is also known for call bets, sometimes called announced bets or racetrack bets. These wagers are based on sections of the physical wheel rather than only on the numerical layout of the betting table.
At a traditional land-based table, a player may announce a call bet and the dealer places the appropriate combination of chips. In online roulette, a racetrack interface may allow players to select these wheel sectors directly.
Common European roulette call bets
- Voisins du Zéro: Covers the wheel section around zero, traditionally using multiple split, corner, and straight-up bets.
- Jeu Zéro: A smaller group of numbers near zero on the wheel.
- Le Tiers du Cylindre: Covers a large wheel section opposite the zero area.
- Orphelins: Covers the numbers not included in Voisins du Zéro or Le Tiers du Cylindre.
Call bets add a classic French roulette flavor and provide a convenient way to wager on wheel geography. They do not change the fundamental house edge on the underlying bets, but they can make it easier to execute a particular coverage pattern.
The American Roulette Five-Number Bet
American roulette includes a wager that is not found in European roulette: the five-number bet, also called the basket bet. It covers 0, 00, 1, 2, and 3.
This bet pays 6:1, but it has a house edge of 7.89%, making it less favorable than other standard American roulette wagers. For players who want to prioritize stronger odds, it is useful to recognize that the five-number bet carries a substantially higher casino advantage than the usual 5.26% American roulette rate.
The five-number bet is a clear reminder that not every roulette wager has the same value, even on the same table. Understanding the bet layout can help players choose options that better match their goals.
Which Version Offers Better Value?
When the choice is between standard American roulette and standard European roulette, European roulette offers the stronger mathematical value.
- European roulette has one fewer green pocket. This directly improves the chance that a standard bet will win.
- European roulette has a lower house edge. The 2.70% edge is materially lower than American roulette's 5.26% edge.
- European roulette has a higher RTP. Its approximately 97.30% RTP compares favorably with American roulette's approximately 94.74% RTP.
- La Partage and En Prison can improve value further. On qualifying even-money bets, either rule can reduce the house edge to about 1.35%.
- European roulette supports classic call bets. These wagers offer additional ways to explore the wheel's layout and traditional roulette betting patterns.
American roulette can still be enjoyable for players who prefer its distinctive double-zero format or encounter it at a favorite venue. However, when the priority is lower house edge and higher theoretical return, the single-zero European wheel is the clear choice.
Can Betting Systems Change Roulette Odds?
Popular roulette staking systems include Martingale, Fibonacci, D'Alembert, and flat betting. These approaches determine how much a player wagers after wins or losses, but they do not alter the probability of the next spin.
Every spin is independent. A previous result does not make a color, number, or wheel section more likely to appear on the following spin. No betting system can remove the house edge or guarantee a profit.
That said, players can use a simple staking plan to manage their entertainment budget. Setting a session limit, choosing stake sizes that feel comfortable, and selecting a lower-house-edge roulette variant are practical ways to make informed decisions.
How to Choose a Roulette Table
A smart roulette choice starts with the wheel type and table rules. Before betting, consider the following checklist:
- Look for a single-zero European roulette wheel whenever it is available.
- Check whether La Partage or En Prison applies to even-money bets.
- Review the table's minimum and maximum stake limits.
- Understand whether the game offers traditional call bets or a digital racetrack betting interface.
- Avoid assuming that higher payouts mean better odds; compare the wheel layout and house edge instead.
- On American roulette, recognize the five-number bet as a higher-house-edge option.
- Set a budget before playing and treat roulette as entertainment rather than a source of guaranteed income.
Final Verdict: European Roulette Is Usually the Better Choice
American and European roulette deliver the same fast-paced casino experience, familiar betting grid, and wide range of payouts. Both allow players to choose between broad coverage bets and high-reward number selections.
Still, the extra 00 pocket on an American wheel makes a measurable difference. Standard European roulette offers a 2.70% house edge and approximately 97.30% RTP, while standard American roulette has a 5.26% house edge and approximately 94.74% RTP. Since the standard payout schedule remains essentially unchanged, the European wheel provides more favorable long-term odds.
For the best available value, look for European roulette with La Partage or En Prison on even-money bets. Those rules can reduce the house edge to approximately 1.35%, combining the classic roulette experience with one of the most player-friendly rule structures in the game.
