Roulette is one of the most recognizable casino games, known for its spinning wheel, numbered pockets, and small ball that determines the winning result. Although the game looks complicated at first, its basic rules are relatively easy to understand. You do not need advanced mathematical knowledge or previous casino experience to learn how it works. Once you understand the numbers, betting options, and payout rules, you can follow a roulette game with greater confidence.
If you are exploring casino games for the first time, this guide to Roulette Explained will help you understand the essential elements before you play. You will discover how the roulette wheel works, what different bets mean, how payouts are calculated, and why European and American roulette have different odds. You will also learn about common mistakes beginners should avoid.
Whether you are interested in traditional casino tables or online roulette, understanding the fundamentals gives you a clearer picture of the game. However, remember that roulette is a game of chance, and no betting approach can guarantee a winning result.
What Is Roulette?
Roulette is a casino game in which you place bets on where a small ball will land on a spinning numbered wheel. The wheel contains numbered pockets, and each pocket has a specific colour. Depending on the version, the numbers range from 0 to 36 or include an additional 00.
The word roulette comes from French and means “little wheel.” The game developed from European gaming traditions and eventually became a popular casino attraction around the world.
The objective is straightforward: you predict the winning number, colour, or number group before the dealer spins the wheel. Once the ball settles into a pocket, the winning bets are identified, and payouts are distributed according to the rules.
How Does a Roulette Game Work?
A traditional roulette game involves a dealer, a roulette wheel, a betting table, and players placing chips on different betting positions.
The process generally follows these steps:
- Place your bets: You select numbers, colours, or number combinations on the betting layout.
- The dealer spins the wheel: The dealer spins the wheel in one direction and releases the ball in the opposite direction.
- The ball settles: The ball eventually falls into one of the numbered pockets.
- The result is announced: The dealer identifies the winning number and colour.
- Payouts are distributed: Winning bets receive payouts according to their odds, while losing bets are collected.
In online roulette, software or a live dealer manages the same process, depending on the game format.
Understanding Roulette Numbers and Colours
Understanding the roulette wheel is essential because its numbers and colours determine the available betting opportunities.
A standard European roulette wheel contains 37 pockets, numbered from 0 to 36. The American version contains 38 pockets because it includes both 0 and 00.
The numbers are arranged in a specific order rather than numerical sequence. This arrangement helps create the traditional roulette wheel layout.
Red, Black, and Green Numbers
Roulette numbers are divided into three colour categories:
- Red: Eighteen numbered pockets are red.
- Black: Eighteen numbered pockets are black.
- Green: The zero pocket is green. American roulette has an additional green 00 pocket.
The colours provide simple betting options. For example, you can place a bet on red if you believe the ball will land in a red pocket.
However, red and black bets are not guaranteed to win half the time. The green zero pockets create an additional possibility that gives the casino its mathematical advantage.
European vs American Roulette
The two most common roulette versions are European and American roulette. Their main difference is the number of pockets on the wheel.
| Feature | European Roulette | American Roulette |
| Total pockets | 37 | 38 |
| Numbers | 0–36 | 0–36 and 00 |
| Green pockets | One | Two |
| Standard house edge | 2.70% | 5.26% |
| Straight-up payout | 35:1 | 35:1 |
European roulette generally offers better mathematical odds because it has only one green pocket.
American roulette has an additional double-zero pocket, which increases the house edge. Therefore, if you are comparing the two versions, understanding this difference can help you make a more informed choice.
Different Types of Roulette Bets
Roulette offers several betting options, ranging from individual numbers to larger number groups. These bets are generally divided into two categories: inside bets and outside bets.
Your selection determines the potential payout and the probability of winning.
Inside Bets
Inside bets involve selecting specific numbers or smaller combinations within the central section of the roulette table. These bets usually offer higher payouts because they cover fewer possible outcomes.
Common inside bets include:
1. Straight-Up Bet
A straight-up bet means selecting one individual number. For example, you might place your chip directly on number 17.
If the ball lands on that number, the standard payout is 35:1. This means a winning $1 bet earns $35 in winnings, in addition to the original stake.
2. Split Bet
A split bet covers two adjacent numbers on the betting layout. You place your chip on the line separating those numbers.
For example, you could select 14 and 17 if they share a dividing line on the table layout. The standard payout is 17:1.
3. Street Bet
A street bet covers three consecutive numbers arranged in one horizontal row.
For example, selecting 1, 2, and 3 gives you three possible winning numbers. The standard payout is 11:1.
4. Corner Bet
A corner bet covers four numbers that meet at one intersection on the betting layout. Its standard payout is 8:1.
5. Six-Line Bet
A six-line bet covers two adjacent rows containing six numbers in total. The standard payout is 5:1.
Outside Bets
Outside bets cover larger groups of numbers. Although their payouts are generally smaller, they offer more winning possibilities than individual-number bets.
Common outside bets include:
- Red or black: You predict which colour will win.
- Odd or even: You select whether the winning number will be odd or even.
- High or low: You choose numbers 1–18 or 19–36.
- Dozens: You select one of three groups: 1–12, 13–24, or 25–36.
- Columns: You select one of the three vertical columns on the betting layout.
Most standard outside bets pay 1:1, while dozen and column bets typically pay 2:1.
Remember that zero and double zero do not count as red, black, odd, even, high, low, or part of any dozen or column.
Roulette Payouts and Odds Explained
Roulette payouts depend on the type of bet you select. Generally, bets covering fewer numbers offer larger payouts, while bets covering more numbers offer smaller payouts.
Understanding the difference between payout and probability is important when learning roulette.
For example, a straight-up bet pays 35:1 because you are selecting only one number. In European roulette, however, that number has a probability of 1 in 37 of winning.
Similarly, a red bet pays 1:1, but the probability of winning is 18 out of 37 because the wheel contains one green zero.
Here are some standard European roulette betting payouts:
| Bet Type | Numbers Covered | Standard Payout |
| Straight-up | 1 | 35:1 |
| Split | 2 | 17:1 |
| Street | 3 | 11:1 |
| Corner | 4 | 8:1 |
| Six-line | 6 | 5:1 |
| Dozen | 12 | 2:1 |
| Column | 12 | 2:1 |
| Red or black | 18 | 1:1 |
| Odd or even | 18 | 1:1 |
These are standard payouts, although specific table rules can vary.
What Is the Roulette House Edge?
The house edge represents the mathematical advantage the casino has over players over a large number of bets.
In European roulette, the standard house edge is approximately 2.70%. In American roulette, it is approximately 5.26%.
This does not mean you automatically lose that percentage during every session. Instead, it represents the long-term mathematical expectation across repeated wagers.
Consequently, roulette should be viewed as entertainment rather than a reliable way to earn money.
Basic Roulette Rules Every Beginner Should Know
Before participating in a roulette game, you should understand a few basic rules. These help you follow the game and avoid confusion when placing bets.
Betting Time and Table Limits
Each roulette table has a minimum and maximum betting limit. You should check these limits before placing chips on the layout.
The dealer announces when betting opens and when no more bets can be placed. Once the dealer calls “no more bets,” you cannot change your selections for that spin.
Winning and Losing Bets
After the ball settles, the dealer announces the winning number and colour.
If your selection matches the result, you receive the appropriate payout. Otherwise, your chips are collected.
For example, if you place a bet on black and the ball lands on a black number, your bet wins. However, if the ball lands on zero, a standard black bet loses in European roulette.
Special Rules in European Roulette
Some European roulette tables offer special rules that can affect outside bets.
La Partage: If the ball lands on zero, an even-money outside bet may return half of your original stake.
En Prison: Under this rule, an even-money bet may remain on the table for the next spin after a zero result. Its outcome depends on the next spin and the table’s specific rules.
These rules can reduce the house edge on qualifying bets. However, they are not available at every roulette table.
Common Roulette Strategies and Beginner Mistakes
Many beginners encounter roulette betting systems when learning the game. These systems provide different ways to organise wagers, but none can change the underlying probabilities.
Popular Betting Systems
Some commonly discussed roulette strategies include:
- Martingale System: You double your previous bet after every loss, aiming to recover earlier losses with a winning even-money bet.
- Fibonacci System: You follow a sequence of numbers to determine your next wager after a loss.
- D’Alembert System: You increase your bet after a loss and decrease it after a win.
- Flat Betting: You place the same amount on every spin.
Although these systems can influence how you manage your betting amounts, they cannot overcome the house edge. Betting limits and available funds also restrict progression systems.
Mistakes You Should Avoid
If you are new to roulette, avoid these common mistakes:
- Believing in guaranteed patterns: Previous spins do not determine the next result.
- Chasing losses: Increasing your bets to recover money can lead to greater losses.
- Ignoring the house edge: Different roulette versions have different mathematical odds.
- Betting without a budget: Decide how much you can afford to lose before playing.
A sensible approach is to understand the rules, set a fixed entertainment budget, and stop when you reach your limit.
Online Roulette vs Traditional Casino Roulette
Roulette is available in both physical casinos and online gaming platforms. Although the basic rules remain similar, the playing experience differs.
Traditional roulette allows you to watch a physical wheel and interact with a dealer. It also provides a social atmosphere that many casino visitors enjoy.
Online roulette offers convenience and different game formats. You may encounter automated roulette, where software determines the result, or live dealer roulette, where a real dealer operates a physical wheel through a video stream.
Before choosing an online platform, check its licensing, security practices, game rules, and available responsible gambling tools. You should also understand the local laws governing online gambling in your location.
