If you’ve ever played roulette in a United States casino, you’ve almost certainly spun the double‑zero wheel. American roulette is the standard in Las Vegas, Atlantic City, and most tribal casinos across the country. But there’s another version that offers a distinctly better chance to win: European roulette. With only one zero on the wheel, the house edge drops from 5.26% to 2.70%, instantly improving your odds. For US players who want to maximize their bankroll, this variant is worth exploring.

Despite its name, European roulette is widely available in the United States, especially in online casinos licensed in states like New Jersey, Pennsylvania, and Michigan. Land‑based venues in Nevada also offer it, though it’s less common than the American version. The key difference is simple: the single zero reduces the number of green pockets from two to one, making every bet more favorable. Understanding the rules, strategies, and where to play can give you a real edge.

The main difference: one zero vs. two zeros

The most obvious change between European and American roulette is the wheel layout. The European wheel has 37 pockets: numbers 1 through 36 plus a single zero. The American wheel adds a double zero, bringing the total to 38 pockets. That extra pocket may seem small, but it shifts the math significantly. In European roulette, the probability of winning a straight‑up bet is 1 in 37, compared to 1 in 38 for the American version. Over time, that translates into a lower house edge.

In contrast, the American wheel adds a double zero, increasing the house edge. This difference is explored in a recent analysis on Axios. The extra pocket shifts the odds significantly.

For US players accustomed to the double‑zero game, the first spin on a European wheel can feel almost identical. The betting layout is the same, and you can still place inside bets (straight, split, street) and outside bets (red/black, odd/even, high/low). The only difference is that the single zero means the “en prison” or “la partage” rule is sometimes applied, which can further reduce the house edge on even‑money bets. Many US online casinos offer these rules, giving you an even better deal.

How the house edge affects your bankroll

The house edge is the mathematical advantage the casino holds over the player. In American roulette, it’s 5.26% on all bets except the five‑number bet (0, 00, 1, 2, 3), which has a whopping 7.89% edge. European roulette’s single zero cuts that to 2.70% on every bet. That means for every $100 wagered, you can expect to lose about $2.70 in European roulette versus $5.26 in American roulette – a difference of nearly 50%.

For US players who grind out long sessions, this edge adds up. If you play $10 bets for an hour, the lower house edge could save you double digits. Casinos in Atlantic City and Philadelphia have started offering European roulette tables to attract savvy players. Online, you’ll find it even more readily, often with live dealer streams from studios in Pennsylvania or New Jersey.

Over a year of steady play, those savings can compound into hundreds of dollars – money better spent elsewhere.

Even small percentage points matter when you’re in it for the long haul.

Betting options and payouts

The betting options are identical in both versions. You can bet on single numbers, groups of numbers, colors, odd/even, or high/low. The payouts are the same: 35:1 for a straight up, 17:1 for a split, 8:1 for a street, and so on. The only difference is that because the European wheel has 37 pockets instead of 38, the true odds are slightly better. For example, a red/black bet in European roulette has 18 winning numbers out of 37, giving a 48.65% chance of winning, compared to 47.37% in American roulette.

One advanced rule that benefits US players is “en prison.” If you make an even‑money bet and the ball lands on zero, your bet is “imprisoned” for the next spin. If it wins, you get your bet back (no profit). If it loses, the casino takes it. This effectively cuts the house edge on even‑money bets in half, to 1.35%. Some US online casinos, such as those in New Jersey, offer this rule. Always check the game’s rules before playing.

European roulette at US land‑based casinos

While European roulette is not as common as American roulette on the Strip, it is available. In Las Vegas, high‑limit rooms at the Wynn, Bellagio, and Aria often have single‑zero tables. The minimum bets are higher, typically $25 or more, but the reduced house edge justifies the cost for serious players. Atlantic City’s Borgata and Harrah’s also offer European roulette in their high‑limit areas. Smaller casinos may not carry it, so call ahead or check the casino’s table game directory online.

If you’re playing in a state where online gambling is legal – such as New Jersey, Pennsylvania, Michigan, West Virginia, or Connecticut – you can find European roulette at dozens of regulated sites. The game is often available in both virtual and live dealer formats. Live dealer European roulette streams from studios in New Jersey, bringing the feel of a real casino to your screen.

Comparing European and American roulette

Feature	European Roulette	American Roulette
Number of pockets	37 (0-36)	38 (0, 00-36)
House edge	2.70%	5.26%
En prison rule	Often available	Rarely available
Straight‑up payout	35:1	35:1
Probability of red/black	48.65%	47.37%

The table above shows the clear advantage of the European version. The lower house edge is the single most important factor for any player looking to stretch their bankroll.

Strategies for US players

No strategy can overcome the house edge over the long term, but European roulette gives you a better starting point. Many US players use the Martingale system, doubling their bet after a loss. Because the European wheel has a higher chance of winning on even‑money bets, the Martingale has a slightly lower risk of hitting the table limit. Other strategies, like the Fibonacci or D’Alembert, also benefit from the reduced edge.

However, the Martingale system can quickly hit table limits, especially after a long losing streak. For a deeper look at how to manage these risks, open the website. There, players can find more detailed advice on bankroll management and alternative strategies.

Another approach is to focus on inside bets. Since the house edge is the same on all bets (2.70%), you can play more aggressive bets without sacrificing relative value. Some players prefer to bet on groups of numbers, such as dozens or columns, which pay 2:1 and have a 32.43% chance of winning. Whatever strategy you choose, remember that each spin is independent. The key is to manage your bankroll and enjoy the game.

Playing European roulette online

US players have access to a wide range of online casinos that offer European roulette. Many of these sites are licensed in New Jersey, Pennsylvania, or Michigan, and they use certified random number generators to ensure fairness. Live dealer versions are particularly popular, as they allow you to watch a real wheel spin from a studio. The social aspect is similar to a land‑based casino, and you can chat with the dealer.

Before you play, make sure the site is regulated by a state gaming commission. Look for seals from the New Jersey Division of Gaming Enforcement or the Pennsylvania Gaming Control Board. These sites are audited for fairness, and they offer secure payment methods like PayPal, online banking, and credit cards. Many also provide generous welcome bonuses, but be sure to read the terms – wagering requirements may apply to roulette differently.

Tips for US players trying European roulette

• Always check the number of zeros on the wheel before playing. European roulette should have a single zero; double‑zero tables are American.
• Look for tables that offer “en prison” or “la partage” rules on even‑money bets. This can cut the house edge to 1.35%.
• If playing online, verify the casino’s license from a US state regulator. Stick to sites in New Jersey, Pennsylvania, Michigan, or West Virginia for the safest experience.
• Start with small bets to get a feel for the European wheel. The pace is similar to American roulette, so you’ll adapt quickly.
• Use a bankroll management strategy. With a 2.70% house edge, you can afford to play longer sessions, but always set a limit.
• Consider live dealer European roulette for a more immersive experience. It’s especially popular at US‑facing sites like DraftKings Casino and BetMGM.
• Avoid the five‑number bet (0, 00, 1, 2, 3) – it doesn’t exist in European roulette, so you’re already ahead.
