Learning how to play roulette starts with one simple idea: place a bet on where a ball will land on a numbered wheel, wait for the spin and receive the fixed payout if the selected outcome wins. The basic game can be understood in minutes, but the table becomes more complicated once straight-up bets, splits, streets, corners, dozens, columns and different wheel types enter the picture.
Anyone learning how to play roulette should understand three things before placing a real-money bet: how many pockets the wheel contains, which numbers a wager covers and how much that wager pays. European roulette has 37 pockets, American roulette has 38, and French roulette normally uses the same single-zero wheel as European roulette but can add special rules such as La Partage or En Prison.
Those differences are not cosmetic. The extra 00 on an American wheel raises the standard house edge from approximately 2.70% to 5.26%, while La Partage can reduce the house edge on eligible French even-money bets to about 1.35%. This guide explains how to play roulette from the first chip to the final payout, including the mathematics behind each major bet.
Roulette is entirely chance-based. Previous results, hot numbers, cold numbers and staking systems cannot predict the next pocket or eliminate the house edge.
How to Play Roulette Step by Step
The quickest way to understand how to play roulette is to follow one complete round. Players select a table, choose their chips, place one or more bets, wait until betting closes and then watch the ball settle into one of the numbered pockets.
A standard round follows six steps:
- Choose The Roulette Version. Check whether the game uses a European, American or French wheel and whether any special zero rules apply.
- Choose A Stake. Select the chip value and decide the total amount being placed at risk during that spin.
- Place One Or More Bets. Chips can cover an individual number, several neighboring numbers or larger groups such as red, black, odd, even, dozens or columns.
- Wait For Betting To Close. In live roulette, the dealer announces “no more bets”; RNG games close the betting window automatically.
- The Wheel Produces A Result. The ball settles in one numbered pocket.
- Winning Bets Are Paid. Losing wagers are removed and winning bets receive the fixed payout shown in the game rules.
That is the core answer to how to play roulette. Unlike blackjack, there is no decision to hit, stand, double or split after betting has closed. Once the wager is on the table, the remaining outcome is determined by the spin.
The Casino Critic casino games guides cover roulette alongside slots, live tables and other casino formats where the rules, RTP and house advantage work differently.
How Does Roulette Work?
To understand how to play roulette, it helps to separate the wheel from the betting layout. The wheel determines the winning outcome, while the table shows the different ways a player can cover that outcome.
Numbers 1–36 are divided evenly between 18 red and 18 black pockets. European and French roulette add one green 0, while American roulette includes both a green 0 and 00. Those zero pockets are essential because they prevent even-money bets such as red/black from being genuine 50/50 propositions.
The numbered grid then allows bets ranging from one number to groups of 18 numbers. Covering fewer numbers produces a larger payout but a lower probability of winning; covering more numbers increases hit probability while reducing the payout.
How to Play Roulette on Different Wheel Types
Anyone researching how to play roulette should check the wheel type before looking at individual betting systems or recent results. The number of zero pockets directly changes the mathematical house edge.
| Roulette Type | Pockets | Zeroes | Standard House Edge | Main Difference |
|---|---|---|---|---|
| European Roulette | 37 | 0 | 2.70% | Single-zero wheel |
| American Roulette | 38 | 0 and 00 | 5.26% | Double-zero wheel |
| French Roulette | 37 | 0 | 2.70% normally | Can offer La Partage or En Prison |
| French with La Partage* | 37 | 0 | About 1.35% on eligible bets | Half of eligible even-money stake returned when zero wins |
*La Partage applies only where the table explicitly offers the rule and only to eligible even-money wagers.
A straight-up number usually pays 35:1 on both 37-pocket and 38-pocket roulette. Because American roulette adds another losing pocket without increasing that payout, the standard casino advantage almost doubles.
How to Play Roulette on a European Wheel
European roulette uses 37 pockets – numbers 1 through 36 plus one green 0. For someone learning how to play roulette, it is the simplest standard wheel for understanding the relationship between payouts and probability.
The probability of one exact number winning is:
1 ÷ 37 = approximately 2.70%.
A red wager covers 18 pockets:
18 ÷ 37 = approximately 48.65%.
Black has the same probability. The remaining 2.70% belongs to zero, which is why red versus black is not a true 50/50 proposition.
The wheel numbers are arranged in a fixed non-sequential order, but that layout does not make individual pockets predictable. If number 17 has failed to appear for 50 spins, its probability on the next fair European spin remains 1 in 37.
How to Play Roulette on an American Wheel
American roulette uses 38 pockets – numbers 1–36, 0 and 00. Anyone learning how to play roulette in the US or at an international casino should check for the second green pocket because it materially changes the mathematics.
A straight-up bet still pays 35:1, but the chance of hitting one exact number falls to:
1 ÷ 38 = approximately 2.63%.
Red or black each cover 18 of 38 outcomes:
18 ÷ 38 = approximately 47.37%.
This produces a standard house edge of about 5.26%.
American roulette also includes the five-number bet covering:
0, 00, 1, 2 and 3.
It commonly pays 6:1 and carries an approximate house edge of 7.89%, making it mathematically less favorable than standard American roulette wagers.
How to Play Roulette on a French Wheel
French roulette normally uses the same 37-pocket single-zero structure as European roulette, so its standard house edge begins at 2.70%. What makes it particularly relevant when learning how to play roulette is that some tables change how eligible even-money bets behave when zero appears.
Two rules are especially important.
La Partage
La Partage means an eligible even-money bet loses only half its value if the ball lands on zero.
Suppose $20 is placed on red and the result is 0. Under normal European rules, the full $20 loses. Under La Partage, $10 is lost and $10 is returned.
On eligible bets such as red/black, odd/even and low/high, that reduces the effective house edge from approximately 2.70% to 1.35%.
En Prison
En Prison can hold an eligible even-money wager for another spin after zero appears rather than settling the full stake immediately. The exact procedure can vary by table, particularly if zero appears again.
That is why anyone checking how to play roulette on a French table should read the individual game's rules instead of assuming every En Prison version settles identically.
How to Play Roulette Using the Table Layout
The betting layout divides roulette wagers into inside bets and outside bets. Understanding this distinction is central to how to play roulette because it shows how coverage, win probability and payout size move together.
Inside wagers cover individual numbers or small groups of neighboring numbers. Outside wagers cover 12 or 18 numbers through categories such as dozens, columns, colors, parity and high/low.
Inside bets typically produce larger payouts because they cover fewer outcomes. Outside bets win more frequently but pay less. On a standard European wheel, however, both categories generally retain the same 2.70% house edge.
How to Play Roulette With Inside Bets
Inside bets cover between one and six numbers on the central numbered grid. When learning how to play roulette, these are the bets that require the most attention to chip placement because putting a chip inside a square, on a line or at an intersection changes the number of pockets covered.
| Bet | Numbers Covered | European Probability | American Probability | Payout |
|---|---|---|---|---|
| Straight Up | 1 | 2.70% | 2.63% | 35:1 |
| Split | 2 | 5.41% | 5.26% | 17:1 |
| Street | 3 | 8.11% | 7.89% | 11:1 |
| Corner | 4 | 10.81% | 10.53% | 8:1 |
| Six Line | 6 | 16.22% | 15.79% | 5:1 |
The payout falls as more numbers are covered because the probability of winning rises.
Straight-Up Bet
A straight-up wager covers one number and commonly pays 35:1. The chip is placed directly inside the selected number box, including zero where permitted.
On European roulette, a straight-up bet has one winning outcome among 37. A $10 winning wager therefore earns:
$10 × 35 = $350 profit.
The original $10 stake is also returned, producing a $360 total return.
Split Bet
A split covers two adjacent numbers and pays 17:1. The chip sits on the line dividing the two boxes.
On a European wheel, two numbers out of 37 produce a winning probability of approximately 5.41%. A successful $10 split earns $170 profit plus the returned $10 stake.
Street Bet
A street covers a horizontal row of three numbers and pays 11:1. Examples include 1–2–3, 10–11–12 and 34–35–36.
On European roulette, the chance of winning a street is:
3 ÷ 37 = approximately 8.11%.
A $10 winning street produces $110 profit plus the returned stake.
Trio Bet
A trio is another three-number wager, normally involving zero. On a standard single-zero table, common examples are 0–1–2 and 0–2–3.
Because a trio covers three pockets, it normally pays the same 11:1 as a street.
Corner Bet
A corner covers four adjoining numbers that meet at one point on the grid. For example, a chip at the intersection of 1, 2, 4 and 5 covers all four.
European probability:
4 ÷ 37 = approximately 10.81%.
The standard payout is 8:1.
Six-Line Bet
A six-line wager covers two neighboring streets, or six numbers in total. It normally pays 5:1.
On a European wheel:
6 ÷ 37 = approximately 16.22%.
These inside bets are essential when learning how to play roulette because they show the direct trade-off between number coverage and payout size.
How to Play Roulette With Outside Bets
Outside bets cover larger sections of the roulette grid and are usually easier for beginners to understand. Anyone learning how to play roulette will encounter red/black, odd/even, high/low, dozens and columns almost immediately.
| Bet | Numbers Covered | European Probability | American Probability | Payout |
|---|---|---|---|---|
| Dozen | 12 | 32.43% | 31.58% | 2:1 |
| Column | 12 | 32.43% | 31.58% | 2:1 |
| Red / Black | 18 | 48.65% | 47.37% | 1:1 |
| Odd / Even | 18 | 48.65% | 47.37% | 1:1 |
| 1–18 / 19–36 | 18 | 48.65% | 47.37% | 1:1 |
Zero and 00 are excluded from these standard outside groups. That is the mathematical reason apparently even bets remain favorable to the casino.
Red or Black
A red/black wager covers all 18 numbers of the chosen color and pays 1:1.
European roulette contains 18 red pockets, 18 black pockets and one green zero. The chance of winning is therefore approximately 48.65%, not 50%.
On American roulette, 0 and 00 reduce the probability further to approximately 47.37%.
Odd or Even
Odd/even also covers 18 numbered pockets and pays 1:1. Zero and 00 are neither odd nor even, so the probabilities are identical to red/black.
Low or High
Low/high divides the numbered grid into:
- 1–18.
- 19–36.
Each side contains 18 numbers and pays 1:1. Again, zero pockets sit outside both groups.
Dozens
Dozens divide numbers 1–36 into three groups:
- First dozen – 1–12.
- Second dozen – 13–24.
- Third dozen – 25–36.
Each covers 12 numbers and pays 2:1.
Columns
Columns also cover 12 numbers and pay 2:1. The grid contains three vertical columns, and the wager is placed in the corresponding box below the numbered layout.
Mathematically, dozens and columns are equivalent on a standard wheel.
How to Play Roulette Around Zero
Understanding the zero section is an important part of learning how to play roulette because several special wagers exist only around the green pockets.
On a single-zero European layout, the first four bet covers:
0, 1, 2 and 3.
It covers four outcomes and normally pays 8:1, just like another standard four-number bet.
American roulette has the distinctive five-number bet covering:
0, 00, 1, 2 and 3.
It normally pays 6:1. Because the bet covers five of 38 outcomes while returning only 6 units of profit per unit staked, its house edge reaches approximately 7.89%.
The five-number wager is therefore an important exception to the usual 5.26% American house edge.
Roulette Payouts Explained
Understanding payouts is essential to how to play roulette because a quoted ratio normally refers to profit, not the total money returned after the win.
For example, a $10 straight-up bet paying 35:1 produces:
$10 × 35 = $350 profit.
The original $10 stake is then returned, giving:
$360 total return.
| Bet | Payout | Profit on $10 Win | Total Return |
|---|---|---|---|
| Straight Up | 35:1 | $350 | $360 |
| Split | 17:1 | $170 | $180 |
| Street / Trio | 11:1 | $110 | $120 |
| Corner | 8:1 | $80 | $90 |
| Six Line | 5:1 | $50 | $60 |
| Dozen / Column | 2:1 | $20 | $30 |
| Red / Black | 1:1 | $10 | $20 |
| Odd / Even | 1:1 | $10 | $20 |
| Low / High | 1:1 | $10 | $20 |
Larger payouts correspond to lower-probability bets. A 35:1 payout is not evidence that a straight-up bet has a better mathematical return than an outside wager.
Roulette Odds vs Payouts
Anyone learning how to play roulette should separate true odds from casino payouts. Probability describes how likely the selected outcome is, while the payout describes what the casino returns when that outcome occurs.
On a European wheel, one selected number has:
- 1 winning outcome.
- 36 losing outcomes.
- True odds of 36 to 1 against.
- Casino payout of 35:1.
That missing unit between fair odds and the actual payout creates the casino's mathematical advantage.
The same principle applies across the standard table. Roulette payouts are deliberately slightly below fair mathematical odds.
What Is the House Edge When You Play Roulette?
A complete explanation of how to play roulette needs to include house edge because it measures the casino's theoretical long-run advantage. It does not predict what will happen in one spin, ten spins or a particular session.
Standard figures are approximately:
- European roulette – 2.70%.
- American roulette – 5.26% on standard bets.
- American five-number bet – 7.89%.
- French La Partage – 1.35% on eligible even-money wagers.
A 2.70% house edge does not mean exactly $2.70 will disappear every time $100 is wagered. Short-term roulette outcomes can vary substantially.
It means that across a sufficiently large theoretical amount of wagering, the game structure produces an expected casino advantage of approximately $2.70 for each $100 wagered.
Does the Bet Type Change the House Edge?
On ordinary European roulette, switching between a straight-up number and red/black changes hit frequency, payout and variance, but the standard 2.70% house edge remains the same.
A straight-up bet wins infrequently and pays 35:1. Red wins much more often but pays only 1:1. The payout structure compensates for most of that probability difference while preserving the same underlying edge created by zero.
Anyone learning how to play roulette should know the exceptions. La Partage changes the treatment of eligible even-money wagers, while the American five-number bet carries a larger house edge than other ordinary double-zero bets.
Is Red or Black Really 50/50?
No. Understanding this is fundamental to how to play roulette because red and black look like two equal sides but the wheel contains at least one additional green result.
On European roulette:
- Red – 18/37 = 48.65%.
- Black – 18/37 = 48.65%.
- Zero – 1/37 = 2.70%.
On American roulette:
- Red – 18/38 = 47.37%.
- Black – 18/38 = 47.37%.
- 0 or 00 – 2/38 = 5.26%.
Without the green pocket, red and black would form a genuine 50/50 split. Zero is what creates the house advantage.
Do Previous Roulette Numbers Matter?
No. Anyone learning how to play roulette should treat every legitimate spin as independent of the result that came immediately before it.
If black lands six times in succession, red is not automatically more likely on spin seven. On a standard European wheel, the next spin still gives red approximately 48.65%, black 48.65% and zero 2.70%.
The same principle applies to individual numbers. A pocket that has not appeared for 100 spins does not become more likely on spin 101.
Believing that an outcome is “due” because it has been absent is the gambler's fallacy. Previous-results boards describe history; they do not change the probability structure of the wheel.
Do Roulette Betting Systems Work?
Betting systems can change stake size from one round to the next, but they do not change how to play roulette mathematically. The ball still has the same probability of entering each pocket regardless of whether the previous stake was increased, reduced or left unchanged.
Popular systems include Martingale, Fibonacci, D'Alembert, Labouchère and Paroli. Many use previous wins or losses to determine the next wager.
Martingale, for example, doubles an even-money stake after every loss. Starting with $5 creates the following sequence:
| Bet | Required Stake | Total Staked After Loss |
|---|---|---|
| 1 | $5 | $5 |
| 2 | $10 | $15 |
| 3 | $20 | $35 |
| 4 | $40 | $75 |
| 5 | $80 | $155 |
| 6 | $160 | $315 |
| 7 | $320 | $635 |
| 8 | $640 | $1,275 |
The progression can become very large after only a short losing sequence. Table limits and finite balances also prevent unlimited doubling.
Most importantly, the expected value of each underlying wager remains negative. Changing the staking sequence does not change the wheel.
How to Play Roulette Online
To understand how to play roulette online, first identify whether the game is RNG-based or streamed from a live dealer table. Both can use the same familiar betting layout and standard payouts, but the result is generated differently.
RNG Roulette
RNG roulette uses software to generate the result of each round. It can run much faster than a physical table and normally provides wheel information, payout rules and betting limits inside the game interface.
Because rounds can be completed quickly, a relatively small stake can create substantial total turnover over a short period. Faster play does not improve the odds.
Live Dealer Roulette
Live roulette streams a dealer and physical wheel from a studio or casino environment. Bets are placed through the online interface before the dealer closes wagering and spins the wheel.
For someone learning how to play roulette online, the main practical difference is pace and presentation rather than the fundamental mathematics. A standard single-zero live table still derives its core house edge from the same 37-pocket structure.
Does Online Roulette Have Different Odds?
Not automatically. A standard online European roulette game using a 37-outcome model has the same fundamental probability structure as a conventional European wheel.
Anyone learning how to play roulette online should instead check the exact version because digital games can differ in:
- Number of zero pockets.
- Special zero rules.
- Table limits.
- Speed.
- Side bets.
- Proprietary multipliers.
- Autoplay availability.
- Bonus eligibility.
- Live versus RNG format.
A faster digital table does not change the percentage house edge merely by completing rounds more quickly, but more spins can increase the total amount wagered during the same period of time.
How Casino Bonuses Affect Roulette
Learning how to play roulette with promotional money requires an additional check because table games often contribute less toward wagering requirements than slots. Some promotions exclude roulette entirely.
A bonus might use:
- Slots – 100% contribution.
- Roulette – 10% contribution.
- Selected live tables – 0%.
- Specific low-edge wagers – excluded.
If roulette contributes 10%, a $10 eligible wager reduces the wagering requirement by only $1.
The exact percentage depends on the promotion and market. The Casino Critic guide to casino wagering requirements explains how game contribution, bonus-only versus deposit-plus-bonus wagering and multipliers such as 10x, 20x and 30x change the actual required turnover.
A casino bonus does not improve the underlying roulette odds.
How to Play Roulette for Beginners
The best way to approach how to play roulette for beginners is not to memorize a staking system. Start by understanding the wheel, table layout, payout schedule and amount placed at risk.
Before the first real-money spin, check these points:
- Identify The Wheel. Confirm whether the table has one zero or two.
- Read The Limits. Check the minimum and maximum stake.
- Check Special Rules. Look for La Partage, En Prison or proprietary rules.
- Understand The Bet. Know exactly how many numbers the wager covers.
- Check The Payout. Separate profit from the returned original stake.
- Ignore Previous-Spin Predictions. Past outcomes do not make the next number due.
- Avoid Guaranteed-Profit Claims. No staking progression removes the house edge.
- Set A Spending Limit Before Play. Decide the maximum amount in advance.
- Check Local Regulation. Online roulette legality and access differ by jurisdiction.
- Stop At The Predefined Limit. A loss does not create an obligation to continue.
That is a more useful framework for how to play roulette than trying to identify a supposedly lucky color or overdue number.
Casino Critic's responsible gambling guide explains financial limits, time-outs, self-exclusion and warning signs such as chasing losses.
Common Mistakes When Learning How to Play Roulette
Many mistakes made by beginners have nothing to do with placing the chip incorrectly. They come from misunderstanding probability.
| Mistake | What Actually Happens |
|---|---|
| Treating red/black as exactly 50/50 | Zero creates an extra losing outcome |
| Missing the American 00 | The standard house edge rises to 5.26% |
| Assuming bigger payout means better value | High payout accompanies lower probability |
| Chasing a “due” number | Previous spins do not alter the next probability |
| Increasing stakes after losses | Bet progression does not remove the edge |
| Ignoring bonus contribution | Roulette may contribute only partly or not at all |
| Confusing house edge with a session result | House edge is a long-run mathematical measure |
| Assuming live roulette is mathematically better | Wheel and rules matter, not the presence of a dealer |
These mistakes are especially important because a player can understand the physical rules of how to play roulette while still misunderstanding the mathematics behind the wagers.
European vs American Roulette With $100 of Turnover
One of the clearest ways to understand how to play roulette across different wheel types is to compare theoretical house-edge exposure over the same amount wagered.
With $100 of total turnover:
- European roulette at 2.70% corresponds to approximately $2.70 theoretical house advantage.
- American roulette at 5.26% corresponds to approximately $5.26 theoretical house advantage.
| Wheel | Standard House Edge | Theoretical House Advantage per $100 Wagered |
|---|---|---|
| European | 2.70% | $2.70 |
| American | 5.26% | $5.26 |
| French La Partage* | 1.35% | $1.35 on eligible even-money bets |
*Only when the rule is offered and applies to the selected bet.
These numbers are not forecasts for one session. A short run can finish ahead, behind or close to the starting balance. The table simply shows how the structural difference between one zero and two affects expected long-run mathematics.
What Is the Lowest-Edge Standard Roulette Option?
For someone researching how to play roulette with the lowest common standard house edge, French single-zero roulette with La Partage on eligible even-money bets can reduce the figure to about 1.35%.
Standard European roulette is approximately 2.70%. Standard American roulette is approximately 5.26%, while the five-number American bet rises to about 7.89%.
A lower house edge does not turn roulette into a positive-expectation game. It simply means the casino's theoretical long-run advantage is smaller.
Roulette Rules in One Table
This table summarizes the most important information needed to understand how to play roulette across the three traditional versions.
| Rule | European | American | French |
|---|---|---|---|
| Numbers | 1–36 | 1–36 | 1–36 |
| Zero | Yes | Yes | Yes |
| Double Zero | No | Yes | No |
| Total Pockets | 37 | 38 | 37 |
| Straight-Up Payout | 35:1 | 35:1 | 35:1 |
| Red/Black Payout | 1:1 | 1:1 | 1:1 |
| Standard House Edge | 2.70% | 5.26% | 2.70% |
| La Partage | Usually no | No | May be available |
| En Prison | Usually no | No | May be available |
| Lowest Common Edge | 2.70% | 5.26% | About 1.35% with La Partage |
The quickest first check is therefore the number of green pockets. One zero or two tells you more about the standard roulette mathematics than a screen full of recent results.
How to Play Roulette Safely Across Global Markets
The basic rules explaining how to play roulette are broadly recognizable around the world, but legal access, age requirements, table features and responsible-gambling controls vary significantly between jurisdictions.
European, American and French refer to game formats rather than guaranteeing that a particular casino is regulated in those regions. A European-style single-zero game can be offered in many countries, just as an American-style double-zero game can appear outside the United States.
Before depositing, verify that online casino gambling is legal in the relevant location and that the operator is authorised for that market. Casino Critic's How We Review methodology separates game mathematics from operator licensing because a familiar roulette table does not prove that the website offering it is properly regulated.
Final Takeaway – How to Play Roulette Without Falling for the Myths
The practical answer to how to play roulette is simple: choose the wheel, select a chip value, place the wager before betting closes and receive the fixed payout if the ball lands on an outcome covered by that bet. Inside wagers cover small groups for larger payouts, while outside bets cover more numbers and pay less.
Understanding how to play roulette properly requires one additional step – recognizing how zero changes the mathematics. European roulette has one zero and a standard 2.70% house edge. American roulette adds 00 and raises that figure to 5.26%. French roulette uses a single-zero wheel but can reduce the edge on eligible even-money wagers where La Partage is available.
No hot number, cold number, previous result or betting progression changes the probability of the next independent spin. For anyone learning how to play roulette, understanding the wheel, coverage and payouts matters far more than memorizing a betting system.
Roulette should be treated as paid entertainment rather than a method of generating income. Gambling laws, minimum ages and legal casino availability differ by market.
