European vs American Roulette: House Edge Compared 2026

The wheel looks the same at first glance, but the choice between European and American roulette is the most important decision a player makes before placing a chip. This guide compares European vs American roulette house edge, explains why one zero beats two, and shows how rules like La Partage and En Prison can lower the cost of play even further.

European vs American Roulette: The Quick Answer

Quick answer: European roulette has 37 pockets (numbers 1 to 36 plus a single zero) and a house edge of 2.70%. American roulette has 38 pockets (an additional double zero) and a house edge of 5.26%. For the same bets, the European wheel costs you about half as much in the long run.

How the Wheels Differ

Both wheels pay 35-to-1 on a single number. The true odds on the European wheel are 36-to-1 against, and on the American wheel they are 37-to-1 against. The payout is the same, but the chance of winning is lower with the extra pocket, and that gap is the house edge.

• European: 37 pockets, 1 zero, house edge 2.70%
• American: 38 pockets, 0 and 00, house edge 5.26%
• Five-number bet (0, 00, 1, 2, 3) on American wheels: house edge 7.89%, the worst bet on the table

The Math

Take a $1 straight-up bet. On the European wheel, you win $35 with a probability of 1/37 and lose $1 with a probability of 36/37. Expected value = (35 x 1/37) - (1 x 36/37) = -1/37 = -2.70%. On the American wheel, it is (35 x 1/38) - (37/38) = -2/38 = -5.26%. Every standard bet on a given wheel has the same house edge, which is why the wheel is so important.

Does the Bet Type Matter?

On both wheels, all the standard bets (straight-up, split, street, corner, dozen, column, red or black, odd or even, high or low) carry the same house edge. Betting on red does not cost less than betting on a single number. The difference is variance. Outside bets win nearly half the time with small payouts, while straight-up bets win rarely with large payouts.

The single exception on American wheels is the five-number bet, which has a higher edge. Avoid it.

La Partage and En Prison: Lower-Edge Rules

Some European tables offer special rules for even-money bets when the ball lands on zero.

La Partage

You lose only half your stake on even-money bets when zero comes up. This cuts the house edge on those bets to 1.35%.

En Prison

Your even-money bet is held for the next spin. If it wins, you get your stake back. The edge on those bets is also about 1.35% under the most common version. We explain both in detail in our guide to betting fundamentals, which covers how rules and payouts determine expected value.

Finding the Best Tables Online

Many online casinos offer both European and American roulette, and some also have French roulette with La Partage. Check the game rules before you play. Live dealer lobbies often have a mix of wheels and side bets. See our list of the live dealer casinos and the top online casinos for sites with a strong selection.

Betting Systems Do Not Change the Math

Systems like the Martingale, Fibonacci and D'Alembert change how wins and losses are distributed but not the expected loss per unit wagered. A Martingale can win small amounts many times, but one long losing streak can wipe out the gains, and table limits stop you from doubling indefinitely. Each spin is independent, which also means the idea that a color is "due" is the gambler's fallacy.

The total amount you expect to lose equals the total amount wagered multiplied by the house edge. If you stake $1,000 in total over a session at 2.70%, the expected loss is $27. At 5.26%, it is $52.60. Our casino strategy page covers money management that fits this reality.

Bankroll and Session Limits

• Decide on a budget before you start, and treat it as the cost of entertainment.
• Choose lower unit sizes to extend your play on the same bankroll.
• Set a time limit, since the pace of online roulette can be fast.
• Do not chase losses.

Be aware of bonus rules. Roulette often counts for little or nothing toward wagering requirements, so read the terms in our guide to the best casino bonuses before using bonus funds on the wheel.

Side Bets and Special Wheels

Some live and RNG roulette tables include multipliers, lightning numbers and other features. These can make payouts more exciting, but they typically lower the player's return by reducing the base payout on regular bets. Check the paytable and compare the effective house edge to a standard European wheel.

Frequently Asked Questions

Which roulette wheel has better odds?

The European wheel. Its 2.70% house edge is roughly half the 5.26% edge of the American wheel.

Is there a bet with a better chance of winning on roulette?

Outside bets like red or black win about 48.6% of the time on a European wheel and about 47.4% on an American wheel. They win more often but pay less, so the house edge is the same as on any other standard bet on the same wheel.

What is French roulette?

It is a European-style wheel with a French layout and, commonly, La Partage on even-money bets, giving a 1.35% edge on those bets.

Can I beat roulette with a system?

No. Every spin is independent, and betting progressions cannot change the house edge. They only change the pattern of wins and losses.

Conclusion

Choose a single-zero wheel, look for La Partage when it is available and never play the five-number bet. Then set a budget and enjoy the game for what it is. Explore more guides on our best online casinos page and keep learning with our casino strategy section.

Quick Comparison Table in Words

If you stake $100 on a spin of European roulette, the expected loss is $2.70. On American roulette it is $5.26, and with La Partage on an even-money bet it is $1.35. Over 200 spins at $10 a spin, that is $2,000 wagered, and the expected loss runs from $27 on a La Partage even-money bet to $54 on a European wheel and $105 on an American wheel. Actual results swing widely around those averages, but the gap is real and it never closes in your favor.
