Online European Roulette in the UK: Rules and Odds
See how the European wheel, table layout and bet types shape the odds, and what to check when choosing an online casino.
How European Roulette Works—and Why the Single Zero Matters
European roulette looks simple: a numbered wheel, a ball, and a bet on where that ball might settle. The important detail is easy to miss, though. The wheel has one green zero, not two. That small difference changes the mathematical balance of every spin.
A European wheel contains 37 pockets altogether. Thirty-six are numbered from 1 to 36, while the remaining pocket is marked 0. The numbers are coloured red or black, with zero standing apart in green. When the croupier—or the random number generator in an online game—sets the spin in motion, the ball can finish in any one of those pockets.
That is the whole event. The previous spin does not push the next ball towards a colour, number or section. A run of black results does not make red “due”, and a zero does not reset the wheel. I have made that mistake myself after watching a few results line up. The wheel does not remember.
What the single zero changes
Most roulette bets are built around the 36 numbered pockets. A red bet covers 18 numbers, for instance, while black covers the other 18. Even so, neither side covers the green zero. On a European wheel, that leaves one pocket outside the bet.
Games: Casino Slots, Table Games and Live Play
That extra pocket is where the casino gets its built-in advantage. A winning even-money bet pays one unit for one unit staked, but there are 18 winning red pockets and 19 losing pockets if you have backed red. The same basic imbalance applies to black, odd, even, high and low bets.
For bets on individual numbers, the same principle appears differently. A straight-up wager selects one pocket, but there are 37 possible landing places on the European wheel. The payout reflects that risk; the green zero still counts as another way for the wager to lose.
Across standard bets, the European format has a house edge of 2.70%. In plain terms, that is the mathematical advantage built into the game over a large number of bets, not a prediction about what will happen during one session. You can win several spins in a row, or lose immediately. The percentage describes the long-run design of the wheel.
That distinction matters when an online casino presents European roulette with bright graphics or a “hot” result panel. The appearance may change, but the single-zero structure remains the part that sets the basic odds.
European and American wheels
American roulette adds one more green pocket: 00, known as double zero. It therefore has 38 pockets:
- 1 to 36;
- 0;
-
The extra pocket makes the casino’s advantage larger because the numbered bets still cover the same numbers, while there is now another green result outside them. The standard American roulette house edge is 5.26%, compared with 2.70% on the European wheel.
That is the key difference between European and American roulette. The colours, numbered range and familiar bet types may look almost identical, but the second zero changes the chance of every standard wager landing successfully. On an American table, the pair of green pockets creates a wider gap between the number of possible outcomes and the area covered by many bets.
For a quick comparison:
| Feature | European roulette | American roulette |
|---|---|---|
| Numbered pockets | 1 to 36 | 1 to 36 |
| Green pockets | 0 | 0 and 00 |
| Total pockets | 37 | 38 |
| House edge | 2.70% | 5.26% |
So when I compare an online European roulette casino with an American version, I start with the wheel rather than the theme, graphics or dealer presentation. A single zero gives the European game the lower standard house edge. It does not turn roulette into a predictable game, and it does not remove the risk of a losing run. It simply means the underlying mathematics is less demanding than on the double-zero wheel.
That is why the zero matters. One pocket looks insignificant on screen. Mathematically, it is the difference between the standard European and American formats.
Finding a UK Casino with European Roulette
Finding European roulette casinos in the UK is less about trusting a polished homepage and more about checking what is actually available after you open the casino lobby. I have made the mistake of seeing a roulette banner, assuming it meant the single-zero version, and only noticing later that the table was a different variant. The name on the tile is not enough.
Start with the game lobby
Use the casino’s search tool or open its roulette category. Look for the words European Roulette, European, or single zero in the game title or rules panel. If the lobby only says “roulette”, open the information screen before depositing. The rules should identify the variant and show the wheel or betting options clearly enough for you to confirm what you are playing.
That check matters when browsing online casinos with European roulette because a site may place several formats beside one another:
- an automated or random-number-generator game;
- a live-dealer table streamed from a studio;
- a branded or themed roulette game;
- another roulette variant with different rules.
A large “roulette” label does not tell you which one you have selected. Nor does a VIP tag automatically mean a European table. European VIP roulette may simply refer to a higher-limit room using the same underlying format, while the actual availability, limits and rules remain specific to that table.
I also check whether the game opens in the browser and whether the rules remain accessible before I sign in with money. A demo or preview can show the interface, but it is not proof that the real-money version is offered on the same terms. The useful question is simple: can you identify the exact game, its rules and its permitted stakes from the casino’s own lobby?
Check the operator before the table
A real-money casino serving players in Great Britain must hold the relevant UK Gambling Commission licence. The UK Gambling Commission, commonly shortened to UKGC, is the regulator for online casino activity in Great Britain and the sole regulator in this market.
Licence Verification
Do not rely on a badge in the footer. Open the UKGC public register and verify the operator’s licence number before depositing.
Do not rely on a badge placed in the footer. Open the UKGC public register and verify the operator’s licence number before depositing. Check that the registered business name matches the casino you are using, not merely a similarly named group or a payment brand. If the casino cannot make that relationship clear, I treat it as a stop sign.
A platform without a valid UKGC licence cannot legally offer real-money live roulette to British residents. Offshore sites may still be visible and technically accessible, but visibility is not the same as permission to serve the British market. The practical protection is missing too: you are outside the UKGC system, so the normal UK framework for licensed operators does not apply.
Look for the basic account safeguards
The licence check is only the first filter. Before making a deposit, look for the controls that should be visible on a UKGC-licensed casino:
- age verification before you can deposit;
- a prompt to set a financial limit before your first deposit;
- account-level controls for managing those limits;
- responsible gambling tools, including self-exclusion;
- an internal complaints procedure;
- access to an approved Alternative Dispute Resolution service.
UK-licensed live casino operators must also offer deposit limits, loss limits, session-time reminders, reality checks, cool-off periods and GamStop self-exclusion. These are not decorative links hidden in a help centre. You should be able to find the relevant controls and explanations without having to negotiate with customer support first.
I pay particular attention to whether the site explains how to close or restrict the account. A casino can have European roulette in its lobby and still be a poor choice if the safer-play controls are difficult to locate. Convenient access matters when you are making decisions under pressure.
Confirm availability for your account
Some casinos show games that are unavailable in a particular jurisdiction, account state or format. After registration, check that the European table is still listed for British players and that the game opens only after the required age and identity checks. A title appearing in a public game catalogue is not a guarantee that you can play it for real money.
I would also check the rules page for the selected table rather than assuming every version on the site works identically. That is where the casino should explain the game type, applicable limits and any special conditions. Keep the page or take a note before depositing. Advertising language is easy; a clear rules screen is harder to fake.
There is no need to assemble a supposed list of the “best” European roulette casinos before doing these checks. First establish that the operator is authorised, the exact single-zero game is available, and the account protections are usable. Only then is it worth comparing the table itself.

What Makes a European Roulette Casino Worth Playing?
A casino can offer European roulette and still be a poor place to play it. I have made that mistake before: I saw the familiar green zero, assumed the game was the whole story, and paid too little attention to the operator around it. The better test is less glamorous. Check what the casino tells you, what it lets you control and how clearly it sets out the rules.
Start with the information, not the welcome offer
A worthwhile UKGC-licensed operator should make the roulette rules easy to find before you deposit. Look for the wheel type, the available table limits, the payout schedule and any special features. The game should not require you to guess whether it is standard European roulette, a modified version or a roulette-themed product with different mechanics.
RTP information also matters. Roulette does not become a better wager because a page calls it “best”; that word often means little more than a large banner. The standard European format has a house edge of 2.70%, while a table with extra rules or altered payouts may produce a different result. If the operator does not explain the game’s return information clearly, I treat that as a reason to slow down rather than deposit.
The same applies to limits. Check the minimum and maximum stake shown at the table, and whether those limits change between the live, automated and random-number versions. A low minimum may suit a cautious session, but a high maximum does not make the game more valuable. It simply gives you more room to lose quickly.
Read the terms that sit outside the table
The casino’s bonus terms can affect how roulette play is counted. Operators may apply different game weighting to live and RNG roulette, and the rate can vary by operator. Live roulette may count at 10% or 20%, while RNG roulette can count at 100%. Some operators exclude live roulette from no-deposit bonus wagering altogether; where it is included, a 0–10% rate may apply.
Bonus Wagering
Since January 2026, licensed operators have been subject to a 10x ceiling on bonus wagering requirements.
That is why I never judge a promotion from the headline alone. Open the full terms and find the section covering eligible games, game weighting, maximum stake rules, excluded tables and withdrawal conditions. Since January 2026, licensed operators have been subject to a 10x ceiling on bonus wagering requirements, but the ceiling is not a promise that every offer is equally useful.
A bonus can look generous and still be awkward for roulette. Bonus funds may have a small game-weighting rate, or the offer may exclude the exact table you wanted to play. I would rather see a plain offer with readable terms than a “huge” promotion hiding the important conditions.
Check the operator’s controls and support
The casino should give you account-level tools before play gets going. New customers must be prompted to set a financial limit before making their first deposit, and the controls for changing account limits should be easy to reach. UKGC-licensed casinos must also provide responsible gambling tools, including self-exclusion.
For live casino operators, the available safeguards include deposit limits, loss limits, session time reminders, reality checks, cool-off periods and GamStop self-exclusion. These are not decorative settings. I have found that a reminder arriving during a long session can interrupt the automatic “one more spin” habit before it turns into a bad decision.
French Roulette Online Casino UK: Rules and Limits
Age verification must happen before a customer can deposit. Credit cards cannot be used for gambling, including credit-card funding routed through a money service business, and wallets that permit credit-card funds for gambling are also barred. Those details tell you whether the operator is behaving like a serious UK-facing business rather than simply placing a roulette game behind a payment button.
Finally, check the licence number on the UK Gambling Commission’s public register before depositing. A UKGC-licensed casino must provide an internal complaints process and access to an approved ADR service, while platforms without a valid UKGC licence cannot legally offer real-money live roulette to British residents.
That is my practical definition of a good operator: clear game information, honest terms, visible controls and a licence you can verify. Nothing flashy. Much safer to assess.
Playing for Real Money: Bets, Payouts and Bonus Terms
Playing European roulette for real money is less complicated than the casino wording sometimes makes it sound. You choose a stake, select a bet before the betting window closes, and collect a payout if the winning number or category matches your selection. I still check the paytable before depositing, because “standard” is not a substitute for seeing the actual rules.
Straight-up Bet
Example: 35:1 × £1 = £36 payout.
A single-number wager is the most direct choice: if your number lands, the payout is 35:1. The same rate applies to a straight-up bet on American roulette, although the extra pocket changes the overall odds rather than this particular payout. A split covers two neighbouring numbers and pays 17:1. A street covers a horizontal row of three numbers and pays 11:1.
The broader choices are outside bets. Red or black, even or odd, and low or high each pay 1:1 when successful. They cover more possible results than a single-number bet, but the return is smaller. That is the basic trade-off: narrower selections offer larger listed payouts, while broader selections offer smaller ones.
| Bet | What it covers | Payout |
|---|---|---|
| Straight-up | One number | 35:1 |
| Split | Two adjacent numbers | 17:1 |
| Street | Three numbers in a horizontal row | 11:1 |
| Red/black, even/odd, high/low | An outside category | 1:1 |
If you want to play European roulette online before risking cash, a demo version can help you learn the buttons and timing. It does not reproduce the financial pressure of real-money play, though. With a cash balance, the sensible starting point is a stake you can afford to lose, followed by a quick check of the table minimum, maximum and paytable. “VIP” often means higher limits and a more polished presentation, not better roulette odds.
Bonus terms need a separate check
The wager amount and the bonus rules are two different things. A roulette bet may be settled at its normal table payout while contributing only part of the required bonus wagering. Across UK operators, roulette game weighting can differ: live roulette may count at 10% or 20%, whereas RNG roulette may count at 100%. Those are not universal settings, so I would read the promotion’s game-contribution table before treating bonus funds as usable bankroll.
Some operators leave live roulette out of no-deposit bonus wagering altogether. Where it is included, a stated contribution rate of 0–10% may apply. A review or headline saying “roulette included” is not enough; the wording in the promotion decides whether your particular game and bet qualify.
Online Casino Without ID in the UK: What It Means
Since January 2026, licensed operators in the UK have a ceiling of 10x on bonus wagering requirements. That limit does not remove the other conditions. Check the expiry wording, eligible game list, maximum qualifying stake and any withdrawal restrictions before opting in. Also remember that roulette wagers can burn through a balance quickly even when the game contributes generously to a promotion.
I have made the mistake of chasing a bonus after overlooking its weighting. The headline looked generous; the qualifying play was not. Read first. Deposit second.
Inside Bets, Outside Bets and the Single-Zero Advantage
The betting areas on a European roulette table fall into two broad groups: inside bets placed on or around individual numbers, and outside bets placed in the wider bands around the numbered grid. On a single-zero wheel, every option is built around the same set of pockets: numbers 1 to 36 plus zero. That makes the layout less intimidating once you see what each section is asking you to cover.
European roulette inside bets
Inside bets sit within the numbered part of the cloth. They let you select a narrow group of numbers, so the possible win is larger but the result depends on fewer pockets.
The main choices are:
- Straight-up: one number, including zero.
- Split: two adjacent numbers joined by a line. A winning split pays 17:1.
- Street: a horizontal row of three numbers. It pays 11:1.
- Corner: four numbers meeting at one point.
- Six line: two adjoining streets, covering six numbers.
The closer your bet gets to one number, the more selective it becomes. That is the useful distinction here—not that one type is “better”, but that each covers a different slice of the single-zero wheel. I have made the mistake of treating a larger payout as a better opportunity. It is only a larger payout if the selected pocket arrives.
Zero needs particular attention. It is not red or black, odd or even, high or low, and it does not belong to the ordinary numbered columns. On a single-zero table, that one green pocket is the house’s built-in advantage over the broad even-money choices.
European roulette outside bets
Outside bets cover wider groups and are easier to read at a glance. The familiar options are:
- Red or black
- Odd or even
- High or low
- Dozens
- Columns
Red/black, odd/even and high/low are even-money bets, paying 1:1. They look close to a coin toss, but zero is the interruption: it wins for neither side. A single-zero wheel therefore gives these bets a lower house edge than the corresponding choices on a wheel with an extra zero.
Dozens and columns divide the numbered grid into larger groups. They exclude zero as well, so a zero result loses the stake. Outside bets can feel calmer because they cover more numbers, but a wider selection does not change the random nature of the spin.
What La Partage changes
Some European tables apply La Partage to even-money bets. When zero appears, half of your stake on red/black, odd/even or high/low is returned instead of the entire wager being lost. That changes the house edge on those bets to 1.35%.
This is a meaningful difference, but it applies only where the rule is offered and only to qualifying even-money wagers. It does not turn the table into a predictable game, nor does it improve an inside bet. I check the rule panel before playing because the green zero is where the practical difference sits.
No Patterns
No betting pattern can identify the next winning pocket.
No betting pattern can identify the next winning pocket. Roulette outcomes are determined by chance, so changing from an inside bet to an outside bet changes coverage and risk, not the result of the next spin.
The Wheel, the Spin and the Pace of Play
The main choice is not only which European roulette game you open, but what kind of wheel sits behind it. Online casinos generally offer either an RNG version or a live-dealer table. Both can use the single-zero European format, yet they feel completely different once the betting window opens.
RNG roulette: quick and compact
RNG roulette does not show a physical wheel. A random number generator determines the simulated result, then the game displays the winning pocket and resets for the next round. The European roulette wheel is represented on screen rather than filmed in a studio.
That makes the rhythm brisk. There is no dealer waiting for bets to close, no ball circling the wheel and no time spent clearing chips from a real layout. You can move from one spin to the next quickly, which suits a short session or anyone who dislikes idle time.
RNG games also tend to support lower minimum stakes, with some available from 10p. That can make a casino with European roulette accessible when you want to test the format without committing much to each round. Still, faster play cuts both ways. I have opened an RNG table intending to play briefly and found that the balance had moved before I had really noticed the passage of time.
The speed is not a sign that the results are easier to influence. Each simulated spin is separate, and the random-number system does not provide a pattern to follow.

Live roulette: a real wheel on camera
Live dealer roulette takes the opposite approach. A studio camera streams a physical European roulette wheel, while a human dealer launches the ball, announces the result and manages the table. You see the wheel, the ball drop and the dealer’s handling of the round rather than a purely digital animation.
That extra process slows the game, but it also gives the table a more recognisable casino feel. You can watch the ball travel around the green-zero wheel and see the result arrive physically. For me, that makes live play less mechanical; the trade-off is that a quiet stretch between spins is part of the experience.
A standard live table is commonly described as running at 80–100 spins per hour. A specialist review reports that speed roulette can exceed 150 spins per hour, though the actual pace depends on the studio and table design. Speed roulette still uses a streamed physical wheel, but removes some of the pauses found at a conventional live table.
The difference is sharper when comparing formats across variants: RNG American roulette is typically listed at 150–200 or more spins per hour, while live dealer play is put at 50–60 spins per hour. Those figures are useful as format markers, not promises for every table.
If you want the feel of a real European roulette casino wheel, choose live dealer. If you value quick rounds and a low entry stake, RNG is the more practical fit. Neither changes the basic chance of where the ball finishes.
Reading the European Roulette Table Layout
A European roulette casino table looks busy until you know what the blocks are doing. The centre is the numbered grid; the surrounding boxes are shortcuts for covering groups of numbers. Once you can read that pattern, moving between a digital felt and a live dealer table becomes much less awkward.
Start with the numbered grid
The main grid runs from 1 to 36, normally arranged in three vertical columns. Each column contains twelve numbers, while the rows run across three neighbouring numbers. The numbers do not appear in simple counting order from left to right, so use the printed labels rather than relying on memory.
Live Dream Catcher Casino UK: Game and Site Guide
At one end sits the green zero. European roulette has 37 pockets altogether: numbers 1 through 36 plus that single zero. On the table, zero is separated from the three-column block, which makes it visually distinct from the numbered squares.
That separation matters when you are locating a bet. A click on a number itself is different from a click on the line or corner touching it. The interface may highlight the selected area, but I still check the chip marker before confirming. I have managed to place a bet beside the intended number rather than on it. Annoying, avoidable.
Read the lines around the grid
Below the numbered columns, you will usually find boxes covering each column. Beside or below those are the dozen areas, each grouping twelve consecutive numbers. These are broad sections of the layout, not extra numbers.
Further out are the even-money areas: red and black, odd and even, and low and high ranges. Their wording and position can vary slightly between software providers, but the visual idea stays familiar: the closer boxes cover specific groups, while the outer boxes cover wider groups.
The small gaps between squares also have a purpose. A marker placed on a shared boundary can represent a combination of neighbouring numbers. On a live European roulette casino table, that is where a dealer places the chip; online, the cursor or touch point selects the corresponding betting zone.
A quick visual check
Before pressing the confirm button, scan three things:
- Is the chip on a number, a shared edge, a row, a column or a larger outside box?
- Does the highlighted area match the part of the felt you meant to select?
- Has the zero area remained clear unless you deliberately included it?
This is useful whether you are following a roulette strategy or simply choosing a few positions. The layout can show where a bet applies; it cannot turn a pattern into a prediction.
Roulette Demos and Themed Slot Games: Know the Difference
A roulette demo is still roulette. It lets you open a digital table and practise placing wagers without using real money. The wheel, numbered pockets, bet types and results follow the game’s roulette rules; the demo simply removes the cash risk. I use demos to learn the controls and see how a particular interface behaves. I do not treat a win there as proof that real-money play will go the same way.
The confusion starts when a title uses roulette in its name but is actually a slot. Searches for a 3D European roulette slot, European Roulette Gold or European Roulette Platinum may lead to products built around the look of a wheel, a casino table or familiar colours. That appearance does not turn the game into European roulette. A slot uses reels, symbols and a programmed paytable. Its bonus features and winning combinations belong to that slot, not to a roulette wheel.
The same warning applies to Book of Dead. It is a slot, not a roulette variant. XXXtreme Lightning Roulette also needs careful reading: despite the roulette theme, it is a separate casino product with its own rules and payout structure. A roulette-style name is not enough. Before you play, open the rules or information panel and check whether the game presents reels and symbols or a wheel with numbered pockets.
Online Slots Payout Percentage: How RTP Works
What “demo” really tells you
A European roulette demo is useful for getting comfortable with the betting screen, chip controls and spin button. It does not tell you that the title is a slot, and it does not make a slot behave like roulette. “Free play” describes the money mode, not the mathematics.
The distinction matters in Britain because online slots have rules that do not apply to roulette. Slot autoplay is banned. Each online slot spin must last at least 2.5 seconds, so a slot cannot be presented as an instant, hands-off sequence of spins. Stake limits also apply: the maximum stake per game cycle is £5 for customers aged 25 and over, and £2 for customers aged 18 to 24. The £5 limit for all adults began on 9 April 2025.
Age checks come before depositing: an operator must verify that you are old enough to gamble before allowing funds into the account. UKGC-licensed casinos also cannot accept credit cards for gambling, including routes that use credit-card funds through a wallet or money service business.
Read the rules first. Names sell the theme; the paytable tells you the game.
Live European Roulette: Dealers, Limits and Safer Play
A live European roulette table gives you a real wheel rather than a computer-generated result. The video comes from a studio, a human dealer launches the ball, and you watch the physical drop before the result is settled. That changes the feel of the game: there is a brief betting window, the dealer closes it, then the wheel does its work in full view.
Live Play Checklist
- Confirm the table minimum and maximum stakes
- Verify the dealer is live and the wheel is physical
- Set your financial limit before the first spin
- Check for visible responsible gambling controls
I have found that the useful part is not the studio gloss. It is seeing the wheel, the ball and the dealer’s actions clearly enough to follow each round. A live casino European roulette table can feel more social than an automated game, but the screen does not turn chance into skill. You still need to decide your stake before betting closes and accept the result once the ball lands.
Check the table minimum
Minimums vary by table and format, so read the information panel before joining. A specialist review of UK tables reports live roulette minimums starting at 10p, while auto-roulette and speed formats can start at 5p. Treat those as table-specific figures, not a promise that every live European roulette casino will offer them.
The minimum is only one part of the decision. If the table moves quickly or the interface makes repeated bets easy, a small stake can still become a sizeable session total. I have made that mistake myself: focusing on the chip value while ignoring how often I was placing it. Set your own financial limit before the first spin.
Safeguards on UKGC-licensed tables
For British players, the UK Gambling Commission regulates online casino activity in Great Britain. A platform without a valid UKGC licence cannot legally offer real-money live roulette to British residents. Before depositing, verify the licence number on the Commission’s public register rather than relying on a badge displayed in the footer.
UKGC-licensed live casino operators must provide practical controls, including:
- deposit limits and loss limits;
- session-time reminders and reality checks;
- cool-off periods;
- self-exclusion through GamStop;
- account-level tools for setting and changing financial limits.
Operators must also check your age before allowing you to deposit. UKGC licensees need an internal complaints route and access to approved Alternative Dispute Resolution if a complaint is not settled directly.
These controls are not decoration. Use them before the first live spin, when changing your mind is easy. If roulette stops feeling recreational, self-exclusion is the cleaner move than trying to win back losses. No clever dealer, table or European wheel changes that.
European vs American Roulette: The Zeroes Change the Odds
Choosing between European roulette and American roulette comes down to the green pockets. A European wheel has numbers 1 to 36 and one zero, giving it 37 pockets. American roulette adds a double zero, so its wheel has 38.
That extra pocket does not look dramatic on the table. It is still one additional green space. But it changes the chance of every standard wager and gives the casino a larger mathematical advantage. European roulette has a house edge of 2.70%, while American roulette is 5.26%.
That is the part I missed when I first treated the two games as interchangeable. The red-and-black layout looks familiar, the common payouts look familiar, and the ball behaves the same way. The cost is hidden in the wheel.
The basket bet deserves extra caution
American roulette also offers the basket bet, covering 0, 00, 1, 2 and 3. Its house edge is 7.89%, higher than the ordinary American game edge. In practical terms, it is one of the least favourable standard choices on the table.
So, when comparing an online European roulette casino game with an American version, check the wheel shown in the rules and not just the game title. A green 00 confirms that you are looking at the American variant. If the game shows only one green zero, the European format is the lower-edge choice.
Neither wheel can predict its next result. The difference is not a strategy or a promise of winning; it is the built-in price of the game. For me, European roulette is the straightforward pick when both versions are available: fewer pockets, a smaller house edge, and no reason to pay extra for a second zero.
The simple choice.
Should I play American or European roulette if I’m in the UK?
European roulette has the lower standard house edge: 2.70%, compared with 5.26% for American roulette. Check the game rules to confirm which wheel you are choosing.
What is the difference between European and American roulette wheels?
European roulette has 37 pockets, including one green zero; American roulette has 38, with both 0 and 00. The extra pocket raises the standard house edge from 2.70% to 5.26%.
How does roulette actually work?
You place a bet on a number, colour or other outcome, then a ball lands in one pocket on the spinning wheel. Each spin is determined by chance, and previous results do not predict the next one.
