For decades, American roulette players have accepted the double-zero wheel as the standard. The green 0 and 00 pockets give the house a built-in advantage that chips away at bankrolls over time. But a quieter shift is happening across the United States: single zero roulette is gaining traction, offering a lower house edge and better odds for players who know where to look. Whether you are in a Las Vegas casino or playing from your living room, understanding this variant can change the way you approach the game.
The appeal is straightforward. Single zero roulette, often called European roulette, uses only one green pocket (0) instead of two. That single change reduces the house edge from 5.26% on a double-zero wheel to just 2.70%. Over hundreds of spins, that difference translates into real money saved. For US players accustomed to the standard American wheel, discovering single zero roulette can feel like finding a hidden advantage.
The Difference Between Single and Double Zero
The core distinction is simple: the number of green pockets. A double-zero wheel has 38 slots (numbers 1-36, plus 0 and 00), while a single-zero wheel has 37 slots (1-36 plus 0). This changes the probability of every bet. For example, a straight-up bet on a single number pays 35 to 1 in both versions, but the odds of hitting are 1 in 37 on a single-zero wheel versus 1 in 38 on a double-zero wheel.
Beyond the math, the layout also differs. Single zero roulette tables typically feature the European-style felt with the zero at the top and a separate section for the “en prison” or “la partage” rules. These rules, common in European casinos, are sometimes offered at US venues and can further reduce the house edge on even-money bets. When the ball lands on zero, your bet may be imprisoned for the next spin or you get half your stake back. That can drop the house edge on those bets to as low as 1.35%.
Why the House Edge Matters
The house edge is the casino’s long-term profit margin. On a double-zero wheel, the casino keeps $5.26 for every $100 wagered. On a single-zero wheel, that drops to $2.70. Over a session of 100 spins at $10 per spin, the expected loss goes from $52.60 to $27.00. That is not a small difference – it is nearly half the cost of playing.
This profit margin is often studied in academic settings. For instance, house edge research is conducted at Arizona State University. Understanding the underlying probability can help players make more informed decisions.
For US players who enjoy extended sessions or use betting systems, the lower edge means your bankroll lasts longer. It also means you need fewer wins to break even. The advantage is especially pronounced on even-money bets like red/black or odd/even. With la partage rules, the effective house edge on those bets can be cut to 1.35%, making single zero roulette one of the most favorable table games in the casino.
Where to Find Single Zero Roulette in the US
Single zero roulette is not as common as its double-zero cousin, but it is increasingly available in American casinos. Las Vegas leads the way, with high-limit rooms at properties like the Wynn, Bellagio, and Aria offering European roulette tables. The Venetian and Palazzo also feature single-zero wheels in their VIP areas. In Atlantic City, the Borgata and Harrah’s have introduced single-zero tables in recent years, responding to player demand.
Regional casinos in states like Pennsylvania, Michigan, and New Jersey have also started adding single zero roulette, especially in their online platforms. The trend is driven by players who have traveled to Europe or played online and discovered the better odds. As competition heats up among US casino operators, offering single zero roulette has become a way to attract savvy gamblers.
Online Casinos Offering Single Zero Roulette
For players who prefer to play from home, online casinos provide the widest access to single zero roulette. Nearly every major US-licensed online casino – especially those in New Jersey, Pennsylvania, Michigan, and West Virginia – offers multiple versions of European roulette. Titles from providers like Evolution Gaming, NetEnt, and Playtech feature high-definition streams, live dealers, and immersive gameplay.
Live dealer single zero roulette is particularly popular because it replicates the land-based experience while giving you the lower house edge. Some online casinos also offer “single zero roulette” as a dedicated game with additional side bets or speed options. The convenience of playing on your phone or computer, combined with the better odds, makes online single zero roulette a strong choice for US players.
Comparing Betting Options
The following table shows how the house edge differs between single zero and double zero roulette for common bet types.
| Bet Type | Single Zero House Edge | Double Zero House Edge |
|---|---|---|
| Straight up | 2.70% | 5.26% |
| Split | 2.70% | 5.26% |
| Street | 2.70% | 5.26% |
| Corner | 2.70% | 5.26% |
| Even-money (no special rules) | 2.70% | 5.26% |
| Even-money (with en prison) | 1.35% | N/A |
Another key difference is the payout structure for the “basket” bet (0, 00, 1, 2, 3) that exists only on double-zero wheels. That bet carries a house edge of 7.89%, making it one of the worst in the casino. Single zero roulette eliminates that trap entirely.
Strategies for Single Zero Roulette
Because the house edge is lower, traditional betting strategies like the Martingale or Fibonacci become slightly more viable on a single-zero wheel. However, no system can overcome the mathematical edge in the long run. The real strategy is to choose single zero roulette whenever possible and to manage your bankroll wisely.
Focus on even-money bets if you want to extend playtime, or mix in inside bets for higher potential payouts. The key is to avoid the sucker bets that casinos push, such as the five-number bet on a double-zero wheel. On a single-zero table, all bets have the same house edge (2.70%) except for the special rules on even-money bets. That uniformity makes it easier to pick a style that fits your risk tolerance.

Key Considerations When Choosing a Single Zero Roulette Game
- Minimum and maximum bet limits: High-limit rooms often have higher minimums, so check the table limit before sitting down.
- Availability of la partage or en prison rules: These rules further reduce the house edge on even-money bets and are a significant advantage.
- Table location: Land-based single zero tables are usually in VIP or high-limit areas; online versions are more accessible.
- Live dealer vs. RNG: Both offer the same odds, but live dealer provides a more authentic experience.
- State regulations: Some states restrict certain roulette variants; verify that single zero roulette is legal in your jurisdiction.
- Game speed: Online versions often allow faster play, which can increase your hourly action – be mindful of that.
- Bonuses and promotions: Online casinos sometimes offer deposit matches or cashback that apply to roulette, adding extra value.
The Rise of European Roulette in America
The growing popularity of single zero roulette in the US mirrors a broader trend of players demanding better odds. Casinos in Las Vegas and Atlantic City have responded by adding more European-style tables, often in response to competition from online platforms where single zero is the default. As more Americans travel abroad or play online, they return expecting the same favorable rules.
This shift is also driven by the rise of “low-edge” gaming. Players today are more educated about house edges and expected value. They seek out games like baccarat, blackjack with favorable rules, and single zero roulette. For casino operators, offering these games is a way to retain knowledgeable customers who might otherwise take their business elsewhere.
Single zero roulette is no longer a niche offering. It is becoming a standard option at major US casino destinations. Whether you are in the high-limit salon at the Wynn or playing on your couch in New Jersey, the opportunity to spin a wheel with only one zero is increasingly within reach.
Now is the time to make the switch. Next time you sit down at a roulette table, look for the single zero layout. If you are playing online, filter for European roulette or single zero variants. The lower house edge gives you a better chance to walk away a winner. Find a reputable casino that offers single zero roulette and put your money where the odds are better. Your bankroll will thank you.
