Quick Answer The core american vs european roulette difference comes down to one number. American wheels have 38 pockets (0, 00, and 1-36), while European wheels have 37 (0 and 1-36). That extra double-zero pocket raises the house edge from 2.7% to 5.26%, making European roulette the better choice for most players.
Why Beginners Get Confused About These Two Games
Walk into any casino, physical or online, and you’ll see roulette tables that look almost identical at first glance. Same red and black pockets. Same betting layout. Same spinning wheel. So why do experienced players insist there’s a meaningful gap between them?
The answer sits in a tiny detail most newcomers overlook: one extra pocket. That single addition changes the math of the entire game, and it’s the reason seasoned gamblers have strong opinions about which version they’ll sit down to play.
This guide breaks down exactly what separates these two roulette variants, how each one affects your odds, and what you need to know before you ever place a chip on the table. By the end, you’ll understand the wheel layout, the betting rules, and the terminology well enough to walk into any casino floor with confidence.
What Is the American vs European Roulette Difference, Really?
At its heart, this comparison is about wheel design. European roulette uses a wheel with 37 numbered pockets: a single zero (0) plus numbers 1 through 36. American roulette adds a second green pocket, the double zero (00), bringing the total to 38 pockets.
Beginners often assume this is a minor cosmetic difference. It isn’t. That extra pocket doesn’t add another betting option worth chasing — it adds another way for the house to win, without adding any extra way for you to win. Every other rule, betting structure, and payout stays roughly the same, which is exactly why this one variable matters so much.
Here’s why new players struggle with this concept: casinos rarely explain it. Tables are usually just labeled “Roulette,” “American Roulette,” or “European Roulette,” and unless you know what to look for, you might play dozens of rounds without realizing which version you chose — or why it matters for your bankroll.
The Rules Explained Step-by-Step
Both versions share the same basic gameplay sequence, so let’s walk through it:
- Place your bets on the table layout before the dealer calls “no more bets.” You can bet on a single number, groups of numbers, colors, odd/even, or ranges.
- The dealer spins the wheel in one direction and rolls a small ball in the opposite direction around the rim.
- The ball loses momentum and drops into one of the numbered pockets as the wheel slows.
- The winning number is announced, and a marker is placed on that number on the table layout.
- Losing bets are cleared from the table by the dealer.
- Winning bets are paid out according to the odds of that specific bet type.
- A new round begins, and betting reopens for the next spin.
The only structural difference happens at step one: on an American table, you have the option to bet on 00 as a standalone number or in combination bets. On a European table, that option simply doesn’t exist because the pocket isn’t there.
How the Wheel and Betting Layout Actually Work

The mechanics of a roulette wheel are simpler than they look once you break them down. Numbers aren’t arranged sequentially around the wheel — they’re deliberately scattered to balance out high and low numbers, odd and even, red and black, on both wheel types.
The betting table (called the “layout”) is where you place chips, and it mirrors the numbers on the wheel. You’ll typically see two categories of bets:
- Inside bets — placed directly on numbers or small groups of numbers (straight up, split, street, corner). These carry higher payouts but lower odds of hitting.
- Outside bets — placed on broader categories like red/black, odd/even, or number ranges (1-18, 19-36). These pay less but hit more often.
The zero and double-zero pockets are usually excluded from outside bets. This means when the ball lands on 0 or 00, most outside bets automatically lose — and this is precisely where the house edge comes from. More green pockets mean more spins where outside bets lose without a corresponding number on your betting options.
Pro Tip: If you’re trying to understand payout odds quickly, remember that a straight-up single number bet pays 35 to 1 on both wheel types — the payout doesn’t change, only your probability of winning does.
Common Beginner Mistakes to Avoid
New players tend to make the same handful of errors when learning these two variants:
- Assuming all roulette tables are identical. Always check the wheel before sitting down — count the green pockets.
- Ignoring the house edge difference. A 2.5 percentage point gap sounds small, but over many spins it meaningfully changes long-term outcomes.
- Confusing “European” with “French” roulette. French roulette uses the same 37-pocket wheel but adds special rules like La Partage, which are not present in standard European tables.
- Betting on 00 out of habit when playing European roulette (where it doesn’t exist) or forgetting it’s available on American tables.
- Overlooking table minimums and maximums, which can vary significantly between the two variants at the same casino.
Understanding these mistakes early saves confusion later, especially if you switch between playing online and at a physical table.
Key Terms and Terminology Explained
Roulette has its own vocabulary, and knowing it makes the game far less intimidating:
- House edge — the mathematical advantage the casino holds over players, expressed as a percentage.
- Inside bet — a wager placed on specific numbers within the number grid.
- Outside bet — a wager placed on broader categories outside the number grid.
- En Prison / La Partage — special rules found in French roulette that return half your stake (or “imprison” it for another spin) when the ball lands on zero.
- Neighbor bets — wagers on numbers physically next to each other on the wheel, not the table layout.
- Call bets — verbal bets on wheel sections, common in European-style games.
Learning this terminology isn’t just academic — it helps you understand dealer announcements and avoid confusion when reading table rules.
Strategy Tips for Understanding the Game Better
There’s no betting system that changes the underlying math of roulette, and any resource claiming otherwise is misleading you. But there are ways to understand the game more clearly:
- Learn the wheel layout, not just the table layout. Knowing which numbers sit near each other physically helps you understand “neighbor” bets and wheel-based strategies used in some variants.
- Track the house edge, not the streaks. Short-term outcomes are random, but the long-term edge is fixed by the wheel design.
- Practice bet-type recognition. Being able to instantly identify inside versus outside bets speeds up your decision-making at the table.
- Compare rule sets before playing. If a European-style table offers La Partage, the effective house edge drops further, which is worth understanding even in a purely educational context.
Pro Tip: Try calculating the probability of a specific bet manually — for example, a single number bet has a 1-in-37 chance on a European wheel versus 1-in-38 on an American wheel. Doing this math yourself cements how the extra pocket actually works.
Myths vs Facts About American and European Roulette
| Myth | Fact |
|---|---|
| “Both wheels have the same odds.” | American wheels have a higher house edge (5.26%) due to the extra 00 pocket. |
| “European roulette and French roulette are identical.” | They share the same wheel, but French roulette includes extra rules like La Partage. |
| “You can predict where the ball will land with practice.” | Wheel outcomes are governed by physics and randomness; no amount of observation reliably predicts results. |
| “The color of your bet affects your odds.” | Red and black bets have identical probability; color has no mathematical advantage. |
| “American roulette pays out more because of the extra number.” | Payout ratios stay the same across both versions; only your odds of winning change. |

Conclusion
Understanding the american vs european roulette difference comes down to three things: the number of pockets, the resulting house edge, and how that single 00 pocket changes your long-term odds without changing any payouts. European wheels give players better mathematical odds, while American wheels offer a familiar, widely available format across many casinos.
Next time you approach a roulette table, take five seconds to count the green pockets before you sit down. It’s a small habit, but it tells you everything about which version of the game you’re about to watch unfold.

FAQs
What is the main american vs european roulette difference?
The main difference is the number of pockets on the wheel. American roulette has 38 pockets, including both a single zero and a double zero. European roulette has only 37 pockets, with just one zero. This extra pocket in the American version increases the house edge from 2.7% to 5.26%, making European wheels statistically more favorable for players.
Why does the double zero increase the house edge?
The double zero pocket doesn’t correspond to any additional bet on the table layout, so outside bets like red/black or odd/even lose whenever the ball lands there. Since American wheels have two such non-matching pockets (0 and 00) instead of one, there are simply more opportunities for outside bets to lose overall.
Is French roulette the same as European roulette?
Not exactly. French roulette uses the same 37-pocket wheel as European roulette, but it typically includes special rules: 1) La Partage, which returns half your stake if the ball lands on zero, and 2) En Prison, which “imprisons” your bet for another spin instead of losing it outright. These rules lower the house edge even further.
Does the american vs european roulette difference affect payouts?
No. Payout ratios for specific bets, such as 35 to 1 for a straight-up number, remain identical across both wheel types. What changes is your probability of winning, not how much you’re paid when you do win. This is a common misconception among beginners.
Which wheel type is more common in physical casinos?
This varies by region. European-style wheels are more common in Europe and many international casinos, while American-style wheels are more prevalent in the United States. Online platforms often offer both, giving players the choice to select based on their own preference and understanding of the odds.
Can you tell the difference between the wheels just by looking?
Yes, fairly easily. Count the green pockets: if you see two green pockets labeled 0 and 00, it’s an American wheel. If you see only one green pocket labeled 0, it’s a European wheel. This quick visual check is the fastest way to identify which version of the game you’re looking at.
