Introduction
When you approach a roulette table, you will usually find two common formats: American roulette and European roulette. Both follow the same basic gameplay of placing bets and watching the wheel spin, but they differ in how the wheel is designed, which affects how each version plays. Understanding these differences can help you decide which format better fits your preferences and style of play.
This guide outlines the core mechanics of each version, including the number of pockets on the wheel and how the house edge is calculated. These factors shape how bets are settled over time, even though each spin is independent and based entirely on chance. Knowing how American and European roulette differ can support informed, responsible play with a focus on enjoyment.

Frequently Asked Questions
Section 1: Understanding the Basics of Roulette
FAQ 1: What is the main difference between American and European roulette?
The main difference between American and European roulette lies in the number of zero pockets on the wheel. American roulette includes both a single zero (0) and a double zero (00), for a total of 38 pockets. European roulette uses only a single zero (0), resulting in 37 pockets. This structural difference influences how the house edge is calculated over time. The presence of the additional zero in American roulette results in a higher house edge compared to the European version.
FAQ 2: How many pockets does an American roulette wheel have?
The 0 and 00 pockets are a defining characteristic of the American version. These additional pockets affect how probabilities are structured within the game and create a higher built-in house edge compared to European roulette.
FAQ 3: How many pockets does a European roulette wheel have?
A European roulette wheel has 37 pockets in total. These include the numbers 1 through 36, shown in red or black, and a single green zero (0) pocket. Unlike the American version, the European wheel does not have a double zero (00) pocket. This single-zero layout affects how the house edge is calculated over time. The simpler wheel design is a defining feature of European roulette and follows standard rules used across many tables.
FAQ 4: What do the ‘0’ and ’00’ pockets mean in roulette?
The ‘0’ and ’00’ pockets in roulette are the house numbers, which means that when the ball lands on one of them, most standard bets do not win. These green pockets are built into the game’s design to create the casino’s mathematical edge. European roulette includes a single ‘0’, while American roulette features both ‘0’ and ’00’. When the ball lands on a zero pocket, outside bets such as red/black or odd/even do not win, and most inside bets are also affected, except for wagers placed directly on the zero pockets. These pockets are a core part of how roulette functions as a casino game.
Section 2: Key Differences in Gameplay and Rules
FAQ 5: How does the house edge differ between American and European roulette?
The house edge differs between American and European roulette due to the number of zero pockets on the wheel. American roulette, which includes two zero pockets (‘0′ and ’00’), has a higher house edge of approximately 5.26%. European roulette, which uses a single ‘0’ pocket, has a lower house edge of about 2.70%. This structural difference affects how the game performs over time. A lower house edge means the game retains a smaller percentage of wagers on average.
FAQ 6: What is the “La Partage” rule, and which roulette version uses it?
The “La Partage” rule is a feature available on some European roulette tables, most commonly in French roulette. It applies only to even-money bets such as red/black, odd/even, or high/low. When an even-money bet is placed, and the ball lands on zero, half of the wager is returned rather than the full amount being lost. This rule reduces the house edge on those specific bets compared to standard European roulette rules. It alters how losses are handled for zero outcomes in even-money wagers.
FAQ 7: What is the “En Prison” rule, and how does it work?
The “En Prison” rule is an option offered on some European roulette tables, often alongside French roulette. It applies only to even-money bets when the ball lands on the single zero. Instead of losing the bet immediately, the wager is held for the next spin. If the bet wins on the following spin, the original stake is returned without additional winnings. If the bet does not win, the full wager is then lost. This rule changes how zero outcomes are handled for even-money bets compared to standard rules.
FAQ 8: Do the betting options change between American and European roulette?
The core betting options in American and European roulette are largely the same, including inside bets such as straight up, split, and street, as well as outside bets like red/black, odd/even, and dozens. American roulette includes an additional option known as the five-number bet, which covers 0, 00, 1, 2, and 3. This wager has a higher house edge, at approximately 7.89%, compared to other roulette bets. Aside from this difference, the main wager types remain consistent, but the probabilities vary because the wheels use a different number of pockets. As a result, similar bets can behave differently depending on the roulette version.
FAQ 9: Which roulette version is generally considered more player-friendly?
European roulette is often described as more player-friendly because it has a lower house edge. With a single zero pocket, the house edge is about 2.70%, compared to 5.26% in American roulette. Some European roulette tables also offer rules such as La Partage or En Prison, which affect how even-money bets are handled when the ball lands on zero. These structural differences influence the game’s mathematical balance and how wagers are resolved over time. Because of this, European roulette is often viewed as a lower house-edge option.
Section 3: Odds and Probabilities Explained
FAQ 10: What are the odds of hitting a single number in American roulette?
In American roulette, the odds of a straight-up bet landing on a specific number are 1 in 38. This is because the wheel contains 38 pockets: numbers 1–36, plus 0 and 00. A straight-up bet covers one number, meaning there is one possible winning outcome out of 38 total outcomes. The standard payout for a single-number win is 35:1. While this payout is fixed, the presence of both 0 and 00 increases the house edge compared to other roulette versions. This means the probability of winning reflects the wheel’s full pocket count.
FAQ 11: What are the odds of hitting a single number in European roulette?
In European roulette, the odds of a straight-up bet landing on a specific number are 1 in 37. This is because the wheel has 37 pockets in total, made up of numbers 1–36 and a single zero (0). A straight-up bet covers one number, which means there is one possible matching outcome out of 37 total outcomes. The standard payout for a single-number result is 35:1. While this payout matches other roulette formats, the single zero results in a lower house edge for this type of bet. This difference comes from the wheel’s structure rather than the payout itself.
FAQ 12: How do even-money bets compare in American vs European roulette?
Even-money bets, such as red/black, odd/even, or high/low, are structured differently in American and European roulette because of the number of pockets on the wheel. In European roulette, these bets cover 18 winning pockets out of 37 total. In American roulette, they cover 18 winning pockets out of 38 total. The difference comes from the additional double zero (00) in American roulette. As a result, the house edge on even-money bets is lower in European roulette than in American roulette. Some European tables also apply rules such as La Partage or En Prison, which affect how even-money bets are handled when the ball lands on zero.
Section 4: Making Your Informed Choice
FAQ 13: Why do most experienced players prefer European roulette?
Many experienced players tend to prefer European roulette because it has a lower house edge. The single zero pocket (0) results in a house edge of about 2.70%, compared to 5.26% in American roulette, which includes both 0 and 00. This structural difference affects how wagers are resolved over time. Some European roulette tables also offer rules such as La Partage or En Prison, which change how even-money bets are handled when the ball lands on zero. Together, these elements explain why European roulette is often described as a lower house-edge option.
FAQ 14: Is American roulette ever a better choice for players?
American roulette is generally considered less favorable from a mathematical standpoint because it has a higher house edge. The inclusion of the double zero (00) increases the casino’s advantage compared to single-zero wheels. That said, some players choose American roulette because it is the version available to them or because they prefer its pace or layout. It also offers the five-number bet, which is unique to this version, although it carries a higher house edge. From an informational standpoint, the key difference is driven by wheel design rather than play mechanics.
FAQ 15: How can I choose the right roulette version for my playing style?
Choosing a roulette version comes down to understanding the rules, the wheel layout, and what you value most in the game. If you prefer a lower house edge, European roulette uses a single zero and may include rules such as La Partage or En Prison. American roulette uses a different wheel layout with an additional zero, which changes the odds. In some locations, one version may simply be more available than the other. Before playing, it helps to check the wheel and table rules so you know which version is in use. Playing smart means understanding how each version works and choosing the one that fits how you want to enjoy the game.
