Roulette looks simple on the surface: a spinning wheel, a bouncing ball, and a layout full of betting options. But the type of roulette you play matters a lot for your long-term results. The biggest reason is the wheel layout, which directly impacts the house edge and the expected return on every bet.
In most casinos and online lobbies, you’ll see two headline variants: European roulette and American roulette. A closely related option, French roulette, often uses the European (single-zero) wheel but may add special rules that can improve the value of certain bets.
This guide breaks down the practical differences that actually affect your play: pocket counts, odds, house edge, payouts, common rule variations (including La Partage and En Prison), table limits, side bets, and how to pick the best table for your goals.
At a Glance: European vs American Roulette
The core difference is the number of zero pockets on the wheel.
| Feature | European Roulette | American Roulette |
|---|---|---|
| Wheel pockets | 37 pockets: 1–36 +0 | 38 pockets: 1–36 +0+00 |
| Typical house edge | ~ 2.70% | ~ 5.26% |
| Best use case | Better overall value for most players and most bet types | Common in some land-based casinos; familiar layout for many US players |
| Common special rules | Sometimes offered as French roulette rules on single-zero wheels | May include the five-number bet (top line) and other US-specific options |
That one extra pocket (the 00) is the reason American roulette generally costs more to play in expected value terms, even though the payouts displayed on the layout look the same.
Wheel Layout: Why 37 vs 38 Pockets Changes Everything
Roulette odds are built on the idea that each pocket has an equal probability of being hit on a fair wheel.
- European roulette probability per pocket: 1 / 37
- American roulette probability per pocket: 1 / 38
Most roulette payouts (like 35 to 1 for a straight-up bet) were originally designed around a 36-number game. The zero pockets are what create the casino advantage.
With one zero, the casino advantage is lower. Add a second zero, and you materially increase the casino’s edge on every spin.
House Edge Explained (European: ~2.70% vs American: ~5.26%)
House edge is the average percentage of each bet the casino expects to keep over the long run. It does not predict short-term outcomes (you can win or lose on any spin), but it’s extremely useful for comparing games and tables.
European roulette house edge
European roulette has 37 pockets. For many common bets, the expected loss rate is:
House edge = 1 / 37 ≈ 0.027027 = 2.7027%
American roulette house edge
American roulette has 38 pockets due to the extra 00. The expected loss rate becomes:
House edge = 2 / 38 ≈ 0.052632 = 5.2632%
In plain terms: American roulette typically has about double the house edge of European roulette. That’s a big deal if you care about expected value, bankroll longevity, and how far your budget can stretch.
How the House Edge Affects Real Bets (Even-Money and Straight-Up)
Two of the most searched and most played roulette bet types are even-money bets (red/black, odd/even, high/low) and straight-up bets (one number). Here’s how the wheel type changes the math.
Even-money bets: Red/Black, Odd/Even, High/Low
Even-money bets pay 1 to 1, but they do not win 50% of the time because of the zero pocket(s).
| Variant | Win probability (even-money) | Lose probability (even-money) | Typical house edge |
|---|---|---|---|
| European (single zero) | 18 / 37 ≈ 48.65% | 19 / 37 ≈ 51.35% | ~ 2.70% |
| American (double zero) | 18 / 38 ≈ 47.37% | 20 / 38 ≈ 52.63% | ~ 5.26% |
On both wheels, the zero pocket(s) make you lose on red/black (unless special rules apply, which we’ll cover in the French roulette section). European roulette simply gives you fewer “automatic loss” outcomes than American roulette.
Straight-up bets: One number
Straight-up bets typically pay 35 to 1 (you win 35 units plus get your 1-unit stake back).
- European straight-up win probability: 1 / 37
- American straight-up win probability: 1 / 38
Even though the win probability is slightly higher in American roulette (because there are more pockets overall, each individual pocket is slightly less likely), the presence of an extra losing pocket across the whole game keeps the house edge higher on American roulette overall. The payout does not increase to compensate for the added 00.
Practical takeaway: if you like making occasional “big hit” number bets, choosing a single-zero game still improves the long-run value compared with double-zero.
Payout Schedules: Usually the Same, but Always Worth Confirming
Most roulette tables use standard payouts, regardless of whether they are European or American. That consistency is nice because it makes tables easy to compare. Still, it’s smart to confirm the payout schedule (especially online) because some rule sets or side bets can vary.
| Bet type | Covers | Typical payout |
|---|---|---|
| Straight-up | 1 number | 35 to 1 |
| Split | 2 numbers | 17 to 1 |
| Street | 3 numbers | 11 to 1 |
| Corner | 4 numbers | 8 to 1 |
| Six line (double street) | 6 numbers | 5 to 1 |
| Dozen | 12 numbers | 2 to 1 |
| Column | 12 numbers | 2 to 1 |
| Even-money (outside bets) | 18 numbers | 1 to 1 |
Because these payouts are “fixed” while the number of losing pockets changes between variants, the wheel layout becomes the key driver of value.
French Roulette: Single-Zero Wheel + Rules That Can Improve Even-Money Bets
French roulette is often played on a single-zero wheel like European roulette, but it may include special rules that apply when the ball lands on 0. Two famous rules are La Partage and En Prison.
La Partage (share)
With La Partage, if you make an even-money bet (like red/black) and the ball lands on 0, you lose only half your stake instead of the full amount.
This rule can materially improve expected value on even-money bets, effectively cutting the house edge on those bets to about:
House edge on even-money with La Partage = 1 / 74 ≈ 1.35%
That’s a meaningful advantage for players who enjoy steady outside betting and want their bankroll to last longer.
En Prison (in prison)
With En Prison, if you place an even-money bet and the ball lands on 0, your stake is “imprisoned” for the next spin rather than lost immediately. On the next spin:
- If your even-money bet wins, you get your original stake back (typically without extra winnings for that imprisoned stake).
- If it loses, you lose the stake.
- If 0 hits again, house rules vary (some keep the stake imprisoned again).
In many implementations, En Prison produces a similar improvement to La Partage for even-money bets, bringing the effective house edge down to around 1.35% on those specific wagers.
What La Partage and En Prison do not change
These rules generally apply to even-money outside bets only. They typically do not improve the house edge on inside bets like straight-ups, splits, and corners. So if you mainly play inside bets, your best upgrade is still choosing a single-zero game rather than relying on French rules.
American Roulette’s Notable Extra: The Five-Number Bet
American roulette tables often feature a unique bet called the five-number bet (sometimes called the top line). It covers:
- 0, 00, 1, 2, 3
A common payout for this bet is 6 to 1. While it looks tempting (more coverage than a corner, bigger payout than a six line), it is widely known as a poor-value bet compared to many standard options, with a higher house edge than the rest of the table.
If your goal is to get the most entertainment and play time per dollar, a simple value-focused approach is: enjoy American roulette if you like the vibe, but consider skipping the five-number bet.
Table Limits and Stakes: Why Minimums and Maximums Matter
Beyond the wheel itself, table limits can have a real impact on your experience, especially if you’re trying to manage a bankroll or test a style of play.
Minimum bets
Minimums vary widely:
- Some land-based tables have higher minimums during peak hours.
- Online roulette often offers lower minimums, which can be great for learning, practicing bet types, or stretching your bankroll.
From a player-benefit perspective, a lower minimum can help you pace your session and keep variance manageable, especially when you’re still building confidence with the layout.
Maximum bets
Maximums matter most if you enjoy larger stakes or structured progression systems. Roulette tables may apply:
- A maximum per bet type (for example, a cap on outside bets).
- A maximum total layout exposure (the most the casino allows you to win on a single spin).
If you plan to play higher stakes, checking the maximums in advance helps you avoid awkward mid-session adjustments.
Side Bets and Rule Variations: What to Look For (Especially Online)
Roulette can come with optional extras that change the feel of the game. These aren’t automatically good or bad, but they are worth understanding so you can choose what fits your goals.
Common “extras” you might see
- Racetrack (neighbors) bets: A quick way to place multiple inside bets around a section of the wheel.
- Call bets (more common in French-style presentation): Bets on wheel sectors, often implemented through the racetrack interface.
- Bonus or multiplier side bets: These can add excitement, but they typically come with different odds and a different house edge than standard roulette bets.
If your priority is classic roulette value, focus first on the fundamentals: single-zero wheel and (if you play outside bets) whether La Partage or En Prison is offered.
Online Availability: Finding the Variant You Want
Online casinos (for example, stake.com) commonly offer:
- European roulette (single zero) as a standard option
- American roulette (double zero), often clearly labeled
- French roulette or “European roulette with French rules,” where you can look for La Partage or En Prison
The main player benefit online is choice: you can often compare multiple tables quickly and pick the combination of wheel type, limits,and rules that best matches your budget and style.
Which Roulette Variant Should You Choose?
Your “best” roulette option depends on what you value most: expected return, tradition, availability, or a specific table experience. These guidelines help you choose confidently.
Choose European roulette if you want better long-run value
- The single 0 creates a lower typical house edge (about 2.70%).
- Your bankroll generally lasts longer compared to double-zero roulette at the same betting level.
- It’s a strong default choice for both inside and outside bettors.
Choose French roulette if you primarily play even-money bets
- If the table offers La Partage or En Prison, even-money bets can have an effective edge around 1.35%.
- This can be especially appealing if you like red/black, odd/even, or high/low and want a more budget-friendly way to play.
Choose American roulette if it’s what’s available (or if you love the format)
- American roulette is common in some casinos and can be a classic, energetic table game experience.
- Knowing the higher typical house edge (about 5.26%) helps you set expectations and plan stakes responsibly.
- If value is your priority, consider treating American roulette as an occasional change of pace rather than your main go-to.
A Quick “Best Table” Checklist (Wheel, Rules, Limits)
If you’re comparing multiple roulette tables (in a casino or online), this short checklist keeps the decision simple and value-focused.
- Wheel type: Prefer single-zero (0) over double-zero (0, 00).
- Even-money rules: If you like outside bets, look for La Partage or En Prison.
- Minimum bet: Pick a minimum that matches your bankroll and desired session length.
- Maximum bet: Ensure it fits your intended stake sizing, especially for outside bets.
- Side bets: Understand which are optional and how they work before adding them to your routine.
- Payouts: Confirm standard payouts (especially online) and be cautious with non-standard rules.
Examples: How the Edge Difference Can Feel in Practice
House edge is a long-run average, not a promise for any one session. Still, comparing the edges can help you understand why single-zero roulette is widely recommended when you have a choice.
Same bet size, different expected cost
Imagine you repeatedly place even-money bets at the same stake level.
- At a 2.70% edge (European), the average cost per unit wagered is lower.
- At a 5.26% edge (American), the average cost per unit wagered is roughly about double.
That difference can translate into more spins, more time at the table, and more room for the natural ups and downs of roulette to play out.
Frequently Asked Questions
Is European roulette always better than American roulette?
From an expected value perspective, European roulette is typically better because the single-zero wheel produces a lower house edge (about 2.70% vs about 5.26%). If you have a choice and your goal is value, single-zero is usually the smart pick.
Is French roulette the same as European roulette?
They often share the same single-zero wheel, but French roulette may add rules like La Partage or En Prison. Those rules can improve the odds specifically for even-money bets.
Do betting systems overcome the house edge?
Roulette outcomes are independent spin to spin, and standard betting systems do not change the underlying probabilities or remove the house edge. What you can control is table selection (single-zero vs double-zero), bet sizing, and choosing rules like La Partage when available.
Are roulette payouts different between European and American tables?
Most standard payouts are the same (for example, 35 to 1 for a straight-up bet). The difference in value comes from the wheel layout, especially the presence of 00 in American roulette.
What’s the single biggest thing to check before playing?
Check whether the wheel is single-zero or double-zero. That one detail is the fastest way to estimate the table’s typical house edge and the long-run value of your bets.
Bottom Line: Pick the Wheel That Works Harder for You
If you’re comparing European vs American roulette, the most player-friendly advantage comes down to the number of zero pockets.European roulette (single zero) usually offers a better long-run deal with a typical house edge around 2.70%, while American roulette (double zero) commonly sits around 5.26%.
Want to push value even further for outside bets? Look for French roulette rules like La Partage or En Prison, which can significantly improve the expected return on even-money wagers.
With the right table choice, you’re not changing the nature of roulette, but you are making a smart, informed decision that can help your bankroll last longer and your overall experience feel more rewarding.
