A Roulette Wheel Has 38 Slots?

Indeed, an American roulette wheel has 38 slots, with numbers 1 to 36, and two additional slots marked 0 and 00. This setup distinguishes it from its European counterpart, which only has 37 slots, with one less zero. The extra slot significantly impacts the house edge and, consequently, the player’s chances of winning.

Composition of the American Roulette Wheel

An American roulette wheel contains 38 compartments or slots. They are alternately colored red and black except for two, the 0 and the 00, which are typically green. The numbers are not in sequential order. This randomness is to disrupt any bias and ensure the outcome of every spin is entirely independent.

American Roulette vs. European Roulette

While both versions of roulette are popular, the significant difference lies in the house edge. European Roulette has a house edge of 2.7% due to its single zero, while the American variant has a higher house edge of 5.26%, courtesy of the extra 00 slot. This difference makes European Roulette a better option for players from a purely statistical perspective.

Understanding the House Edge

The house edge refers to the mathematical advantage that the casino has over the players in the long run. In American Roulette, the house edge of 5.26% means that for every $100 wagered, the casino will, on average, profit $5.26. However, this doesn’t mean that every player will lose – far from it. Some players will win, and others will lose. The house edge simply gives the casino a better chance of coming out ahead over time.

Strategies in American Roulette

Despite the higher house edge, strategies can be used to optimize your play in American Roulette. The Martingale, Fibonacci, and D’Alembert systems can all be applied to this game. However, it’s crucial to remember that no strategy can overcome the house edge completely. Roulette, like all casino games, should primarily be a form of entertainment.


To sum up, an American roulette wheel does indeed have 38 slots, with the inclusion of an extra 00 slot setting it apart from European roulette and increasing the house edge. However, this does not detract from the excitement and potential rewards of the game. It remains a popular choice in casinos around the world, with players attracted by its simplicity, range of betting options, and the thrill of the spinning wheel.
