How to Play Roulette – Rules, Bets, Odds & Beginner’s Guide
Roulette is one of the most recognisable casino table games, built around a spinning wheel, a small ball and a numbered betting layout. Players predict where the ball will land by selecting individual numbers, groups of numbers or broader outcomes such as red or black. In this Casinos Like guide, we explain how roulette works, the differences between European and American roulette, the available bets and their payouts, and how to understand the odds before playing.
Important: Roulette is a game of chance. Every spin is independent, and no betting system can reliably predict the next result or eliminate the house edge. The interactive roulette tool on this page is for educational practice only and uses no real money.
What Is Roulette?
Roulette is a casino game in which players place bets on where a ball will settle on a numbered wheel. In European roulette, the wheel contains 37 pockets numbered 0 to 36. American roulette has 38 pockets because it includes both 0 and 00.
Numbers from 1 to 36 are coloured red or black, while the zero pockets are green. Bets can cover a single number or multiple outcomes, with payouts reflecting how many winning pockets a wager covers.
The Roulette Wheel
A rotating wheel contains numbered pockets. The ball eventually settles into one pocket to determine the result.
The Objective
Correctly predict a number, group of numbers or category such as red, black, odd or even.
Roulette Payouts
Winning bets receive payouts according to the selected wager type. More specific bets generally offer higher payouts but lower probabilities.
How to Play Roulette Step by Step
- Choose a roulette variation. Check whether the table uses a European, French or American wheel and review its rules.
- Understand the betting layout. Identify individual numbers, number groups and outside betting options.
- Select a bet. Place chips on the relevant betting area before the betting period closes.
- The wheel spins. The dealer spins the wheel and releases the ball in the opposite direction, or a digital game generates a result according to its rules.
- The winning number is announced. Once the ball settles, the winning number and colour are confirmed.
- Bets are settled. Winning wagers receive the stated payout, while losing wagers are collected, subject to any special table rules.
European vs American vs French Roulette
| Roulette Type | Wheel Pockets | Standard House Edge | Main Difference |
|---|---|---|---|
| European Roulette | 37 (0–36) | 2.70% | One green zero pocket. |
| American Roulette | 38 (0, 00, 1–36) | 5.26% | Two green pockets, increasing the standard house edge. |
| French Roulette | 37 (0–36) | 2.70% normally; approximately 1.35% on eligible even-money bets with La Partage | May include La Partage or En Prison rules. |
House-edge figures assume standard payouts. Special wagers or different table rules can change the mathematical advantage.
Understanding Inside Roulette Bets
Inside bets are placed on individual numbers or small groups of adjacent numbers on the betting layout. They generally offer higher payouts than outside bets, but have a lower probability of winning on any given spin.
| Bet Type | Numbers Covered | Standard Payout |
|---|---|---|
| Straight Up | 1 number | 35:1 |
| Split | 2 numbers | 17:1 |
| Street | 3 numbers | 11:1 |
| Corner | 4 numbers | 8:1 |
| Six Line | 6 numbers | 5:1 |
Understanding Outside Roulette Bets
Outside bets cover larger groups of numbers and are generally easier to recognise on the betting layout. These bets pay less than straight-up wagers because they cover more possible winning outcomes.
Red or Black
Covers the 18 red or 18 black numbers. Standard payout: 1:1. Zero is neither red nor black.
Odd or Even
Covers the 18 odd or 18 even numbers from 1 to 36. Standard payout: 1:1.
Low or High
Covers numbers 1–18 or 19–36. Standard payout: 1:1.
Dozens
Covers 1–12, 13–24 or 25–36. Standard payout: 2:1.
Columns
Covers one of three 12-number columns on the betting layout. Standard payout: 2:1.
Zero
Zero is a separate green pocket. It generally causes standard outside bets to lose, unless special rules apply.
Interactive Roulette Payout Calculator
Enter an example stake and select a bet type to calculate the potential payout, total return and probability of winning on a European roulette wheel.
Understanding the Result
A £10 even-money bet pays £10 profit plus the £10 original stake if successful. Its probability of winning on a European wheel is 18 out of 37.
These figures show standard theoretical payouts and probabilities, not predicted winnings. The calculator does not place bets or connect to a casino.
Try Our Free Virtual Roulette Wheel
Use this interactive European roulette demonstration to select a simple bet and reveal a randomly generated result. The game has 37 equally likely outcomes and uses virtual outcomes only. No deposits, prizes or real-money stakes are involved.
The wheel is a decorative illustration rather than a numbered physical-wheel simulation. The outcome is generated independently and shown in the centre and number grid. Past results do not influence future spins.
What Is the Roulette House Edge?
The house edge represents the casino’s theoretical long-run advantage. For example, on a European roulette wheel, a standard red bet covers 18 of 37 possible outcomes and pays 1:1. Because zero is neither red nor black, the true winning probability is approximately 48.65%, rather than 50%.
Over a very large number of standard bets, the mathematical expected loss is approximately 2.70% of the total amount wagered on European roulette and 5.26% on American roulette. Individual sessions can vary substantially from these averages.
Roulette strategy warning: Systems such as Martingale, Fibonacci and D’Alembert change stake sizes but cannot change the probability of the wheel outcomes. Increasing bets after losses can rapidly increase financial risk.
Beginner Roulette Tips
Understand the Wheel
Check whether the game uses one or two zero pockets and review any special rules before playing.
Learn the Bet Types
Inside bets cover fewer numbers, while outside bets cover larger groups. Neither removes the house edge.
Know the Payouts
A higher advertised payout corresponds to a lower chance of winning, not necessarily a better-value bet.
Avoid Chasing Losses
Do not increase stakes simply because previous spins were unsuccessful. Each spin is independent.
Use Practice Tools
Free educational demonstrations can help you understand the betting layout without financial exposure.
Set Personal Limits
Decide when to stop before playing and avoid gambling with money needed for essential expenses.
Common Roulette Mistakes to Avoid
Believing a Number Is Due
Previous outcomes do not make a particular number or colour more likely on the next independent spin.
Confusing Payout and Return
A 35:1 straight-up payout means £35 profit per £1 wagered, plus the original £1 stake returned on a win.
Ignoring Zero
The zero pocket creates the standard house advantage and affects outside bets.
Using Progressive Betting Systems
Increasing stakes after losses can lead to large bets, bankroll exhaustion or table-limit restrictions.
Misreading Table Limits
Roulette tables can impose minimum and maximum stakes for different bet categories.
Playing Without Breaks
Extended sessions can make it harder to monitor spending and make clear decisions.
Roulette FAQs
How do you play roulette for beginners?
Choose a roulette game, review its betting layout, select a number or group of outcomes, and place a bet before the wheel spins. If the ball lands on a covered outcome, the bet wins according to the table’s payout rules.
What is the difference between European and American roulette?
European roulette has 37 pockets, including one zero. American roulette has 38 pockets, including zero and double zero. Under standard payouts, American roulette has a higher house edge.
What does red or black pay in roulette?
Standard red or black bets pay 1:1. A £10 winning bet produces £10 profit and returns the original £10 stake.
What does a straight-up roulette bet mean?
A straight-up bet covers one individual number. It typically pays 35:1 if that number wins.
What happens when the ball lands on zero?
Standard outside bets normally lose when zero appears. Some French roulette tables apply La Partage or En Prison rules to eligible even-money bets.
Is roulette based on skill or luck?
Roulette outcomes are determined by chance. Understanding probabilities and table rules can help players make informed decisions, but it does not allow them to predict winning numbers.
Can you predict the next roulette number?
No reliable method can predict the next result on a fair, properly functioning roulette wheel. Each spin is independent of previous outcomes.
Does the Martingale roulette strategy work?
Martingale involves increasing stakes after losses. It does not remove the house edge and can expose players to rapidly increasing losses or table limits.
Which roulette variation has the lowest house edge?
French roulette with La Partage can offer an approximately 1.35% house edge on eligible even-money bets. Standard European roulette has a 2.70% house edge.
Can I practise roulette without real money?
