Roulette is the undisputed symbol of the casino floor, an elegant game of chance that has captivated players for centuries.
While the basic rules are identical, there is a fundamental difference between the European and American versions of the game.
The difference between the two games comes down to a single, tiny pocket on the wheel, but the mathematical impact is massive.
We will break down the wheel layouts, the odds, and the house edge associated with each variant.
The Zeroes: What Separates the Two Games
The layout of the numbers is different, but the true impact lies in the number of zeroes in play.
Because there is only one zero, the total number of possible outcomes on a European wheel is 37.
When the game was brought to America, casino owners greedily added a second green pocket, the double zero (00), to increase their profits.
Adding one extra slot to the wheel drastically alters the probabilities without changing the payouts.
The zeroes are the casino's primary source of profit on even-money bets; the American wheel doubles the casino's advantage.
Why the House Edge Matters in Roulette
The house edge is the built-in percentage of your bet that the casino expects to keep over the long term.
If you hit a single number on either wheel, the dealer will hand you 35 chips for every 1 chip you bet.
Because the payout (35 to 1) is only slightly lower than the true odds (36 to 1), the house edge is a very reasonable 2.70%.
Despite the worse odds, the American game still only pays 35 to 1, significantly short-changing the player.
A 5.26% edge will drain your bankroll twice as fast as the European version, offering you zero additional benefits.
La Partage and En Prison Rules
If you want the absolute best odds possible, you should look specifically for French Roulette tables.
These rules significantly reduce the sting of losing a 50/50 bet to the casino's built-in advantage.
This simple rule effectively cuts the house edge on even-money bets in half, down to an incredibly low 1.35%.
Both rules provide massive mathematical value to the player, making French Roulette the most profitable version to play.
Unfortunately, French Roulette tables are rare in physical casinos outside of Europe, but they are easy to find online.
Quick Reference: Which Game is Best?
- American Roulette: 38 pockets (0 and 00). House edge is 5.26%. The worst option available.
- The European Wheel: Features only one zero. A fair 2.70% edge. The most common good table available.
- French Roulette: 37 pockets with La Partage rule. House edge is 1.35% on even-money bets. The absolute best choice.
- Live Dealer: Always check if the live stream is using an American or European wheel before sitting down.
- The Math: The only true strategy is picking the wheel with the lowest built-in casino advantage.
Odds and Payouts Breakdown
| Game Aspect | European Layout | American Layout |
|---|---|---|
| Total Pockets | 37 (1-36 + 0) | 38 (1-36 + 0 + 00) |
| Win Ratio | Fixed at 35 units | Fixed at 35 units |
| True Odds of Winning | 36 to 1 Against | 37 to 1 Against |
| Casino Profit Margin | Fair (2.7%) | Predatory (5.26%) |
Playing the American version is essentially volunteering to give the casino double the money for the exact same entertainment.
However, online casinos offer both versions to all players, giving you the power to choose the better odds.
Always inspect the digital wheel or the live dealer's layout before you place your first chip.
Good luck at the tables, and may the ball always avoid the green pockets when you need it most.
