How Many Numbers Are on a Roulette Wheel?
A standard roulette wheel features a specific number of pockets where the ball can land, defining the game's odds and appeal. The count varies between the two main versions: European and American roulette. Knowing how many numbers are on the wheel is the first step to understanding the game's mathematics and choosing your preferred variant.
This number directly influences the house edge and the probability of your bets winning. While the layout may seem complex, the total is easy to remember once you know the key difference between the single-zero and double-zero designs.
European Roulette: 37 Numbers
The European roulette wheel contains 37 numbered pockets. These include the numbers 1 through 36, alternating between red and black, and a single green zero. This configuration creates a house edge of 2.7% for even-money bets, making it the preferred version for strategy-focused players.
American Roulette: 38 Numbers
The American roulette wheel has 38 pockets. It includes numbers 1 through 36 (red and black), a single green zero (0), and an additional green double-zero (00). This extra number increases the house edge to 5.26% on even-money bets, which is significantly less favourable for the player.
French Roulette Numbers
French roulette uses the same 37-number wheel as the European version. Its defining features are the special rules 'La Partage' and 'En Prison,' which apply to even-money bets when the ball lands on zero. These rules effectively halve the house edge on those bets to about 1.35%.
Why the Number Count Matters
The total number of pockets determines your true odds of winning a straight-up bet on a single number. In European roulette, the odds are 1 in 37, while the payout is 35 to 1. This difference is where the house derives its mathematical advantage.
When choosing a game, always check which wheel is in use. Opting for European or French roulette over the American version is one of the simplest ways to improve your theoretical chances, as the lower house edge means your bankroll may last longer.
- More numbers mean a higher house edge (American: 38 pockets).
- Fewer numbers mean a lower house edge (European: 37 pockets).
- The number count fixes the probability for every type of bet.
- Always verify the wheel type before you start playing.
