The most important roulette choice is not red or black. It is European or American. The difference is a single pocket on the wheel, but that pocket nearly doubles the common house edge. European roulette has one zero. American roulette has zero and double zero. The payouts are mostly the same, which is why the math changes so sharply.
This article compares European and American roulette in practical terms: wheel layout, odds, house edge, session cost, and when a player should simply choose a different table.
The Wheel Difference
European roulette has 37 pockets: numbers 1 through 36 plus a single zero. American roulette has 38 pockets: numbers 1 through 36 plus zero and double zero. The extra double-zero pocket gives the casino another winning number while standard payouts remain unchanged.
On a straight-up number bet, European roulette gives you a 1 in 37 chance. American roulette gives you a 1 in 38 chance. Both typically pay 35:1. That mismatch between true odds and payout is the house edge.
House Edge Comparison
| Version | Pockets | Straight-Up Probability | Common House Edge |
|---|---|---|---|
| European | 37 | 1/37, about 2.70% | About 2.70% |
| American | 38 | 1/38, about 2.63% | About 5.26% |
The straight-up hit probability looks close, but the house edge is the key. A 35:1 payout would be fairer on a 36-pocket wheel. The zero pockets create the gap. Two zero pockets create a bigger gap.
Even-Money Bets
Red/black, odd/even, and high/low cover 18 numbers. On European roulette, 18 winning numbers out of 37 means the bet wins about 48.65% of the time and loses on the 18 opposite numbers plus zero. On American roulette, it wins 18 out of 38, or about 47.37%, and loses to the opposite side plus zero and double zero.
This is why American roulette is not just “one extra number.” That extra pocket appears in every standard bet’s expectation.
Session Cost Example
Imagine two players each make $1,000 in total roulette wagers. On European roulette, the theoretical cost at 2.70% is about $27. On American roulette, the theoretical cost at 5.26% is about $52.60. The difference is $25.60 per $1,000 wagered.
For a short session, either player can win or lose more than the theoretical cost. Over repeated play, the cheaper wheel matters. If a casino offers both, choosing American roulette without a reason is like paying a higher entertainment tax.
What About French Roulette?
French roulette usually uses a European single-zero wheel and may add rules such as la partage or en prison on even-money bets. La partage returns half of an even-money bet when zero hits, reducing the house edge on those bets to about 1.35%. This makes French roulette especially attractive for cautious even-money players when available.
Why Do Casinos Offer American Roulette?
American roulette is familiar in many land-based US casinos, and some players like the layout or do not notice the cost. Online casinos may offer both versions because players search for both. From an affiliate content perspective, a casino review should reward operators that make European and French options easy to find.
Historical Note
Roulette’s roots are European, with the single-zero wheel becoming the more player-friendly standard in many markets. The double-zero wheel became strongly associated with American casinos. The game experience is nearly identical to casual eyes, but the economics are not. That is why history matters here: regional tradition changed the price of the same basic game.
Bet Types: Does the Difference Change?
Most standard bets on the same wheel carry the same house edge. A straight-up bet is more volatile than red/black, but the house edge on European roulette remains about 2.70% for most standard bets. On American roulette, most standard bets sit around 5.26%. The exception is special bets such as the American five-number bet, which can be even worse.
Practical Recommendation
This recommendation should shape Best Roulette Casinos rankings.
If you are a beginner, choose European roulette when available. If French roulette with la partage is available and you like even-money bets, consider that first. Choose American roulette only if you knowingly accept the higher house edge for availability, familiarity, or entertainment preference.
How Casino101 Should Review Roulette Casinos
A roulette casino review should list whether European, French, American, live dealer, and RNG roulette are available. It should identify table limits, speed, mobile usability, and whether la partage or en prison rules exist. A casino with ten roulette tables is not automatically better than one with three if the three include better rules.
Internal Reading Path
This comparison should link from Roulette Guide and into Roulette Strategy Guide. It should also support Best Roulette Casinos pages because wheel availability is one of the most important ranking factors.
FAQ
Is European roulette always better?
Mathematically, it is usually better than American roulette because of the lower house edge. Personal preference may differ, but the cost difference is real.
Does American roulette pay more?
Usually no. Standard payouts are mostly the same, despite the extra double-zero pocket.
What is la partage?
It is a French roulette rule where half of an even-money bet is returned if zero hits, reducing the house edge on those bets.

Why the Double Zero Matters More Than It Looks
Players often see American roulette as almost identical because one extra pocket is visually small. But the payout table does not compensate for the extra pocket. A 35:1 straight-up payout on 38 pockets creates more casino advantage than the same payout on 37 pockets. The game feels the same; the expected cost is not the same.
Bankroll Example
Suppose a player makes 100 spins at $5 per spin, for $500 in total wagering. On European roulette, theoretical cost is about $13.50. On American roulette, it is about $26.30. Over one evening, variance can overwhelm that difference. Over many sessions, choosing European is one of the easiest roulette improvements a player can make.
When American Roulette Might Still Be Chosen
A player might choose American roulette because it is the only live table available at a preferred casino, because friends are playing, or because they enjoy the layout. That is a personal entertainment choice. The important thing is to label it accurately: it is a higher-cost version. Casino101 should not present American and European roulette as equal options.
French Roulette as the Quiet Winner
When la partage is available, even-money bets become much more attractive because half the stake is returned on zero. The house edge on those bets can drop to about 1.35%, making French roulette one of the lower-edge roulette formats. The tradeoff is availability: not every casino offers it, and not every live provider labels the rules clearly.
Review Checklist for Roulette Pages
- Does the casino offer European roulette?
- Does it offer French roulette with la partage or en prison?
- Are American tables clearly labeled?
- Are minimum bets suitable for beginners?
- Are live dealer tables stable on mobile?
- Do roulette bets contribute to bonus wagering?
Internal Link Opportunity
This comparison should be linked from every roulette article because it is the easiest actionable decision. A reader may ignore complex systems, but they can choose a single-zero wheel. That one choice often matters more than any betting pattern.
Search Intent Notes
Readers comparing European and American roulette usually want a direct recommendation. Give it clearly: choose European when available because the common house edge is lower. Then explain the numbers. This structure satisfies quick readers while still giving enough depth for SEO and trust.
Editorial Notes Before Publishing
Before publishing, add a comparison graphic or table near the top, then link to Roulette Guide, Roulette Strategy Guide, Martingale Strategy Explained, and Best Roulette Casinos. This article should become one of the strongest internal links in the roulette cluster because it answers the most actionable roulette question.
Bottom Line for Beginners
If a casino lobby shows both wheels, choose European. If it offers French roulette with la partage and you like even-money bets, compare that first. If only American roulette is available, lower the stake or consider a different game. This one decision is more practical than memorizing a betting system because it changes the mathematical price before the first spin.
Casino101 should make this recommendation visible in every roulette casino review.
Final Comparison Reminder
The European vs American decision is one of the rare casino choices where the better option is easy to explain and easy to act on. Single zero beats double zero for most players because it lowers the common house edge before any strategy discussion begins. That is the message readers should remember after leaving the page.
Every roulette cluster article should reinforce it.
Practical Publishing Note
When this article is reviewed for publication, keep the recommendation clear, add visible internal links, and avoid any wording that implies roulette can be beaten by timing, streaks, or pattern recognition. The strength of this page is honest math.
