If you’re comparing European vs American roulette or researching casino roulette, you’re already thinking like a smart player. The headline difference is simple and powerful: single zero vs double zero. That one extra pocket on the American wheel changes the math behind roulette odds, shifts the roulette house edge, and can significantly affect your long-term results.
This guide breaks down the wheel and layout differences, shows clear probability calculations, explains French roulette rules like La Partage and En Prison, and finishes with practical tips to help you pick the best roulette to play (in casinos and online).
Quick head-to-head: European vs American roulette
Here’s the cleanest comparison. If you remember one thing, remember this: fewer zero pockets usually means better player value.
| Feature | European roulette | American roulette |
|---|---|---|
| Wheel pockets | 37 pockets (numbers 1–36 plus 0) | 38 pockets (numbers 1–36 plus 0 and 00) |
| Zero configuration | Single zero (0) | Double zero (0 and 00) |
| House edge (typical) | About 2.70% | About 5.26% |
| RTP (typical) | About 97.30% | About 94.74% |
| Common variants | European roulette, French roulette (often with special rules) | American roulette (common in many US casinos) |
| Best for value | Usually better, especially with French rules | Usually worse due to the extra 00 pocket |
In plain terms: American roulette roughly doubles the house edge compared to European roulette, because the payouts generally stay the same while one more losing pocket is added.
Why the zero pocket matters so much
Most standard roulette bets pay as if there are 36 “fair” number outcomes (1–36). The zero pockets (0, and 00 on American wheels) are the built-in advantage for the casino.
When you place a bet, your payout doesn’t increase to compensate for the extra zero pocket on American roulette. So the probability of winning goes down, but the reward stays the same. That gap is the roulette house edge.
Roulette odds: simple probability calculations you can actually use
Let’s put numbers on it. In both European and American roulette, the most common bets have the same payout structure, but different win probabilities.
Example 1: Straight-up bet (one number)
A straight-up bet (also called a single number bet) pays 35 to 1. That means:
- If you bet 1 unit and win, you profit 35 units (and get your 1 unit back).
- If you lose, you lose your 1 unit bet.
European roulette (37 pockets):
- Probability of winning = 1 / 37 ≈2.7027%
- Probability of losing = 36 / 37 ≈97.2973%
American roulette (38 pockets):
- Probability of winning = 1 / 38 ≈2.6316%
- Probability of losing = 37 / 38 ≈97.3684%
The odds difference looks small on a single spin, but over time it matters because the extra 00 increases how often you hit a non-paying outcome.
Example 2: Even-money bet (Red/Black, Odd/Even, High/Low)
Even-money bets pay 1 to 1. On paper, you might think you have a 50% chance. In roulette, the zero pocket(s) are the reason it’s not 50/50.
European roulette:
- Win outcomes = 18 (e.g., 18 red numbers)
- Lose outcomes = 18 (the opposite color)
- Zero outcomes = 1 (0)
- Probability of winning = 18 / 37 ≈48.6486%
- Probability of losing = 19 / 37 ≈51.3514% (this includes the 0)
American roulette:
- Win outcomes = 18
- Lose outcomes = 18
- Zero outcomes = 2 (0 and 00)
- Probability of winning = 18 / 38 ≈47.3684%
- Probability of losing = 20 / 38 ≈52.6316% (this includes 0 and 00)
That extra zero pocket reduces your win rate by about 1.28 percentage points on even-money bets (48.65% down to 47.37%).
Roulette house edge and RTP: what they mean (and the exact numbers)
RTP (Return to Player) and house edge are two ways of describing the same concept from opposite sides:
- House edge= the casino’s average advantage on a bet type over the long run.
- RTP= 100% minus the house edge.
European roulette house edge (single zero)
European roulette has 37 pockets. With standard payouts, the house edge is:
House edge = 1 / 37 ≈ 2.7027%
So the RTP is:
RTP = 36 / 37 ≈ 97.2973%
American roulette house edge (double zero)
American roulette has 38 pockets. With standard payouts, the house edge is:
House edge = 2 / 38 = 1 / 19 ≈ 5.2632%
So the RTP is:
RTP = 18 / 19 ≈ 94.7368%
This is why players searching for the best roulette to play usually prioritize single zero vs double zero first. It’s one of the clearest, most reliable ways to improve your expected value without changing your playing style.
French roulette: same wheel, often better rules on even-money bets
French roulette typically uses a single-zero wheel (37 pockets), like European roulette. What makes it stand out is that some casinos (especially in classic French-style rulesets) apply special rules on even-money bets when the ball lands on 0.
Two famous rules are La Partage and En Prison. These don’t usually change the base payouts; they change what happens on a zero result.
La Partage: “share” the loss on even-money bets
With La Partage, if you place an even-money bet (like Red/Black) and the ball lands on 0, you lose only half your bet instead of the full amount.
That reduction meaningfully improves the effective odds on even-money bets, lowering the house edge from about 2.70% to about 1.35% on those bets.
En Prison: “imprison” the bet for a second chance
With En Prison, if you make an even-money bet and the ball lands on 0, your bet is “imprisoned” for the next spin rather than lost immediately.
- If your bet wins on the next spin, you typically get your stake back (depending on house rules), effectively avoiding a loss.
- If it loses on the next spin, you lose the stake.
In many standard interpretations, En Prison provides a similar effective reduction to the house edge on even-money bets as La Partage, bringing it down to roughly 1.35% for those bets.
What French rules do not do
It’s important to keep expectations realistic and factual:
- These rules generally apply to even-money bets only (not to straight-up number bets, splits, streets, corners, or dozens/columns).
- They don’t “beat” roulette. They simply make specific bets more favorable.
Still, if you prefer even-money betting (common for beginners and casual players), French roulette with La Partage or En Prison is often among the strongest options for value.
Wheel number sequence and table layout: what changes (and what doesn’t)
When comparing European vs American roulette, many players wonder whether the order of numbers on the wheel changes the odds. The key point:
The sequence does not change the mathematical house edge by itself. Each pocket is still one pocket, and each spin is designed to be an independent event.
That said, you may notice differences that affect the playing experience:
- Wheel number sequence: European and American wheels typically use different arrangements, which can change how the game “feels” and how you track results visually.
- Table layout: American roulette tables include an extra space for 00. That’s the meaningful structural difference.
- Betting limits: Minimum and maximum bets can vary widely by casino, table, and whether it’s online or live dealer.
For most players, the best practical takeaway is to focus on the zero configuration first, then choose a table with limits that match your bankroll.
Online roulette and live dealer roulette: how the comparison works digitally
Online roulette has made it easier than ever to choose between single-zero and double-zero games. You’re not limited to whatever wheel happens to be on the casino floor.
RNG (digital) roulette
RNG roulette uses software to generate random outcomes. The same core math applies:
- Single-zero RNG roulette mirrors European rules and typically carries an RTP around 97.30%.
- Double-zero RNG roulette mirrors American rules and typically carries an RTP around 94.74%.
The big benefit online is convenience and choice: you can often pick the exact variant you want and play at your preferred pace.
Live dealer roulette
Live roulette streams a real wheel with a human dealer, combining the atmosphere of a casino with the accessibility of online play. When selecting a live table, the same value rules apply:
- Look for European or French live roulette for the single-zero edge.
- If available, choose French live tables that clearly state La Partage or En Prison for better even-money value.
Because table limits vary, live dealer roulette can be excellent for structured bankroll play: you can choose a low-minimum table for longer sessions or a higher-limit table if you prefer fewer, larger wagers.
Best roulette to play: a practical ranking for player value
If your goal is to maximize value while keeping the game simple, here’s a practical way to think about the best roulette to play.
1) French roulette with La Partage or En Prison (best for even-money bettors)
- Single-zero wheel (good baseline)
- Even-money bets can have a lower effective house edge (often around 1.35%)
- Great fit if you like Red/Black, Odd/Even, High/Low
2) European roulette (strong all-around choice)
- Single-zero wheel
- Low standard house edge (about 2.70%)
- Widely available in casinos and online
3) American roulette (playable, but lower value)
- Double-zero wheel
- Higher house edge (about 5.26%)
- Consider it when it’s the only option, or when table conditions (limits, vibe) are your priority
This ranking is purely about expected value from the wheel and rules, not about entertainment. If you enjoy the faster pace or the feel of a specific table, that can still be a valid reason to play. But if you’re optimizing odds, single-zero wins.
Player tips that instantly improve your roulette experience
Roulette is a negative expectation game in the long run, but you can make smarter choices that help your bankroll last longer and give you more play for your money.
Tip 1: Prefer single-zero wheels whenever possible
This is the most impactful decision you can make before you place a chip. Choosing European (single zero) rather than American (double zero) improves RTP from about 94.74% to about 97.30%.
Tip 2: If you like even-money bets, seek La Partage or En Prison
When available, these French rules can improve the effective value of Red/Black and similar bets by reducing what happens on 0.
Tip 3: Set a bankroll and a session plan
- Pick a session bankroll you’re comfortable spending as entertainment.
- Choose a table minimum that lets you place many bets (more spins, more fun, more time).
- Decide in advance what “done for the day” means (a time limit, a win goal, or a loss limit).
Tip 4: Don’t confuse streaks with patterns
Roulette outcomes can clump (streaks happen), but a streak doesn’t change the next spin’s probabilities. Treat “systems” that promise guaranteed profit with healthy skepticism.
Tip 5: Use bet types to match your goals (volatility control)
- Even-money bets offer frequent wins but smaller payouts.
- Inside bets (like straight-up or splits) offer bigger payouts but hit less often.
Neither category beats the house edge by itself, but choosing the right volatility can make your session feel better aligned with your style.
FAQ: European vs American roulette, RTP, rules, and strategy misconceptions
Which is better: European vs American roulette?
For player value, European roulette is typically better because it uses a single zero (37 pockets) and has a lower roulette house edge of about 2.70% (RTP ≈97.30%).American roulette has an extra 00 pocket (38 pockets), raising the house edge to about 5.26% (RTP ≈94.74%).
What does “single zero vs double zero” actually change?
It changes the number of losing outcomes without improving payouts. With one extra zero pocket, the American wheel reduces your chance of winning most bets, which increases the casino’s advantage.
Is French roulette the same as European roulette?
They often share the same single-zero wheel, but French roulette may include rules like La Partage or En Prison that can reduce losses on even-money bets when a 0 appears. Those rules can lower the effective house edge on even-money bets to roughly 1.35%.
Do roulette odds change based on the wheel number sequence?
The wheel’s number order does not change the underlying probability of landing on a given pocket, assuming a fair wheel and random outcomes. The key driver of roulette odds in the European vs American comparison is the presence of 0 versus 0 and 00.
What is the RTP of roulette?
Typical RTP depends on the variant:
- European (single zero): RTP ≈97.30%
- American (double zero): RTP ≈94.74%
French roulette with La Partage or En Prison can improve the effective RTP on even-money bets compared to standard European rules.
Can any betting strategy overcome the roulette house edge?
No betting progression changes the built-in house edge over the long run. Strategies can change variance (how swingy results feel) and help you manage a session, but they do not turn negative expectation into guaranteed profit.
What’s the best roulette to play if I only bet Red/Black?
If your main bet is Red/Black, the best roulette to play is typically French roulette with La Partage or En Prison (when offered). If those rules aren’t available, choose European roulette (single zero) over American (double zero).
Bottom line: choose the wheel that gives you more value per spin
The European vs American roulette decision is one of the few casino choices where you can clearly improve your odds before you even place a bet. If you want better roulette odds, aim for single zero vs double zero every time.
- Pick European roulette to benefit from the lower roulette house edge (about 2.70%).
- If available, pick French roulette with La Partage or En Prison for a potentially stronger even-money experience.
- Use bankroll management to make sessions last longer and feel more in control.
More value per spin means more time at the table, smoother sessions, and a better overall roulette experience—without needing to chase complicated systems.
