Roulette is the wheel-and-ball game that has defined the look of a casino floor for more than two centuries. A spinning wheel, a small ivory ball, and a catalogue of bets ranging from even-money outsides to single-number insides paying 35 to 1. This guide covers how MrMega rates roulette games, how the wheel and table actually work, and which variants are worth your time.
How We Rate Roulette Games
We score every roulette game with the same five-criterion rubric, whether the table is a live-dealer stream or an instant-spin RNG release. The aim is simple. A strong score means the wheel is fair, the rules favour the player where possible, and the operator does nothing that bleeds extra house edge out of the game.
- Wheel type and zero count (weight 35 percent)
- Payout structure and house edge (weight 25 percent)
- Game variety and providers (weight 15 percent)
- Live dealer quality and studio production (weight 15 percent)
- Mobile performance and interface clarity (weight 10 percent)
Wheel Type and Zero Count
The house edge on a roulette table is driven almost entirely by how many zero pockets the wheel carries. A European wheel has a single zero and a 2.70 percent edge. An American wheel adds a double-zero pocket and lifts the edge to 5.26 percent, almost exactly double. A French wheel uses the same single-zero layout as European roulette but applies En Prison or La Partage rules on even-money bets, which cuts the edge in half again to 1.35 percent. We favour single-zero wheels, and we favour French rules most of all.
Payout Structure and House Edge
The payouts on inside and outside bets should match the standard schedule that every fair roulette table uses. A straight-up single number pays 35 to 1, a split pays 17 to 1, a corner pays 8 to 1, an even-money outside bet pays 1 to 1. Any operator that pays less than these ratios is quietly increasing the house edge on the player’s shoulders. We flag any table that deviates from the standard schedule, regardless of how the wheel is built.
Game Variety and Providers
We score library depth and studio pedigree. A strong roulette library includes European, French, and American RNG tables, a credible live-dealer suite, and game-show variants such as Lightning Roulette and Quantum Roulette. Studios with well-earned reputations include Evolution, Playtech, Pragmatic Play Live, Ezugi, and NetEnt Live.
Live Dealer Quality
Live roulette tables are scored on stream quality, croupier training, camera angles on the wheel, and table variety. A good live stream runs at broadcast-grade frame rates, shows a clear racetrack for call bets, and offers at least one low-stake table for new players.
Mobile and Interface
Mobile roulette should behave on a mid-range phone the same way it behaves on desktop. Chip selection must be one tap away, the racetrack should render cleanly on a small screen, and the paytable must be visible without leaving the table.

How Roulette Works
The mechanics are simpler than the strategy conversations that surround them. Players place chips on the betting grid, the croupier spins the wheel and releases the ball in the opposite direction, and the ball eventually lands in a numbered pocket. Winning bets are paid at fixed ratios and a new round begins.
Object of the Game
Predict which numbered pocket the ball will land in, or predict a property of that pocket (red or black, odd or even, low or high, a column, a dozen). Every bet carries the same house edge for a given wheel. The only way to change the edge is to change the wheel, not the bet.
The Wheel, Layout and Ball
A European wheel carries 37 pockets numbered 0 to 36, alternating red and black with a green zero. An American wheel adds a double-zero pocket for 38 total. The numbers on the wheel are not arranged in numerical order, they are arranged to balance odd and even, red and black, and high and low. The ball is designed to bounce several times before settling, which is why no croupier can reliably aim for a pocket.
The Croupier and the Spin Cycle
The croupier runs the table. They call for bets, spin the wheel, release the ball, announce “no more bets” as the ball slows, identify the winning number, and settle payouts. On a live-streamed table the croupier follows the same script, with chip animations appearing on screen for online players.
Placing Bets and the Dolly
Players place chips directly on the betting grid (the layout). Inside bets go on or between numbers, outside bets go on the red or black, odd or even, column or dozen boxes. Once the ball lands, the croupier places a small marker called the dolly on the winning number. No chips may be added or removed while the dolly is in place, to preserve the payout record for that round.
Bet Types and Payouts
Roulette bets split into three families. Inside bets sit on or between specific numbers and pay the highest ratios. Outside bets cover larger groups (colours, odds and evens, dozens, columns) and pay lower ratios. Call bets are groups defined by their position on the wheel rather than on the layout. Every family shares the same house edge for a given wheel.
Inside Bets
Inside bets are the high-variance end of the layout. A straight-up bet on a single number pays 35 to 1 but hits roughly 1 in 37 spins on a European wheel. The table below lists the standard inside and outside payouts against the probability of hitting on a single-zero wheel.
| Bet Type | Payout | European Wheel Probability |
|---|---|---|
| Straight up (single number) | 35 to 1 | 2.70 percent |
| Split (two numbers) | 17 to 1 | 5.41 percent |
| Street (three numbers) | 11 to 1 | 8.11 percent |
| Corner (four numbers) | 8 to 1 | 10.81 percent |
| Six line (six numbers) | 5 to 1 | 16.22 percent |
| Column or dozen | 2 to 1 | 32.43 percent |
| Red or black, odd or even, low or high | 1 to 1 | 48.65 percent |
Outside Bets
Outside bets cover broad groups and hit close to half the time. Red or black, odd or even, and 1 to 18 or 19 to 36 all pay 1 to 1. Column and dozen bets pay 2 to 1. Outside bets are where bankroll lasts longest, because wins come frequently and stakes survive dry spells. The house still takes its 2.70 percent on a European wheel, it just takes it more quietly.
Call Bets and Announced Bets
Call bets are groups of numbers defined by their position around the wheel, not on the layout. They are usually placed via a racetrack on the side of the table, most common on French and European roulette.
- Voisins du Zero covers 17 numbers nearest the zero pocket
- Tiers du Cylindre covers 12 numbers opposite the zero
- Orphelins covers the 8 numbers that fall outside the other two groups
- Neighbours (or finales) covers a selected number and a few of its wheel neighbours
House Edge Across Wheel Types
The house edge depends entirely on the wheel. European runs at 2.70 percent on every bet. American runs at 5.26 percent because of the extra double-zero pocket. French runs at 2.70 percent on inside bets but drops to 1.35 percent on even-money outsides, thanks to En Prison or La Partage. The five-number top-line bet on an American wheel (0, 00, 1, 2, 3) runs at 7.89 percent and should be avoided.
Roulette Strategy
Roulette is a negative-expectation game on every bet, on every wheel, on every spin. Betting systems change the shape of your session, not the house edge. Some smooth out variance, some amplify it, none shift the long-run expectation. A good session strategy aims at bankroll survival and entertainment, not at beating the wheel.
Martingale and Flat Betting
The Martingale doubles the stake after every loss on an even-money bet, so that the first win recovers every prior loss and nets one base unit of profit. It works right up until a losing streak hits the table limit or empties the bankroll, and both happen more often than players expect. Flat betting (the same stake every spin) is the opposite extreme and the sanest default.
Fibonacci, D’Alembert and Labouchere
Fibonacci raises stakes along the Fibonacci sequence after a loss and drops back two steps after a win. D’Alembert adds one unit after a loss and subtracts one after a win, gentler than the Martingale. Labouchere uses a written list where each wager equals the first plus the last, crossed off on a win and extended on a loss. All three feel clever in the moment, none beats the edge, and each has the same long-run expected loss as flat betting.
Why No System Beats the Wheel
Every spin is independent of the last. A string of seven reds tells you nothing about the eighth spin, because the ball and the pockets have no memory. That independence is why no staking system can shift the expected return. Anyone selling a guaranteed roulette system is selling a story, not a mathematical advantage.
Bankroll and Session Limits
Set a loss cap before the session starts, divide your bankroll into enough base-stake units to ride out a bad run (40 to 60 units is a reasonable minimum), and walk away when the cap is reached. If you choose a progressive system like Martingale, divide by much more (200 units or more). Disciplined bankroll management does more to preserve a session than any individual bet choice.
Roulette Variants and Formats
Variants differ by wheel and by rules. Formats differ by how the spin is delivered. Both matter. The variant sets the house edge, the format sets the pace and the atmosphere. A French table beats an American table on the maths, a live-dealer stream beats an RNG table on the atmosphere, and a well-rated lobby offers all of them.
A Short History Note
Roulette traces its roots to 17th-century France, where Blaise Pascal invented an early wheel in 1655 while trying to build a perpetual-motion machine. The modern single-zero wheel appeared in Germany in the 1840s, when the Blanc brothers removed the double-zero pocket to attract players with a lower house edge. The double-zero survived in the United States and became the American wheel, which is why the two coexist today.
European Roulette
The standard single-zero wheel used across most of Europe. 37 pockets, one green zero, a 2.70 percent house edge on every bet. No En Prison or La Partage rules on even-money outsides, so a zero result simply loses those bets outright. European is the baseline table most lobbies lead with, and almost always a better choice than American.
American Roulette
The double-zero wheel. 38 pockets, two green zeros (0 and 00), a 5.26 percent house edge on every bet, and a particularly bad 7.89 percent edge on the top-line five-number bet. American roulette shortens a bankroll roughly twice as fast as a European wheel, for an otherwise identical game.
French Roulette, En Prison and La Partage
French roulette uses the European single-zero wheel and adds either En Prison or La Partage on even-money outside bets. La Partage returns half the stake when the ball lands on zero, immediately. En Prison locks the losing stake for one more spin, and if the second spin wins, the player gets the stake back (no profit, no further loss). Either rule halves the house edge on even-money bets to 1.35 percent, which is the lowest house edge in mainstream roulette. French roulette is the mathematically best standard table in any lobby that offers it.
Lightning, Quantum and Game-Show Variants
Lightning Roulette (Evolution), Quantum Roulette (Playtech), and a growing catalogue of game-show variants apply random multipliers (up to 500 times stake) to a handful of straight-up numbers on each spin. The multipliers come at a cost, paying 29 to 1 instead of 35 to 1 on unboosted straight-up wins. House edge runs around 2.90 to 3 percent, slightly higher than a standard single-zero wheel. They are entertainment products, not edge-improvement products.
Live Dealer vs RNG Roulette
Live dealer roulette streams a real croupier at a real wheel, with broadcast-grade production and a shared table across many online players. RNG roulette is simulated by software, instant and solo, with a new spin available on demand. Both can run any of the variants above. Live tables feel closer to a land-based casino, RNG tables play faster and support lower stakes. The wheel governs the edge, the format governs the experience.
| Variant | Wheel | Zero Pockets | House Edge (standard bet) |
|---|---|---|---|
| European | Single zero | 1 | 2.70 percent |
| American | Double zero | 2 | 5.26 percent |
| French (with En Prison or La Partage) | Single zero | 1 | 1.35 percent on even-money bets |
| Lightning and Quantum | Single zero (with multipliers) | 1 | Around 2.90 to 3 percent |
| Mini roulette | Single zero, 13 pockets | 1 | Around 3.85 percent |

Free Play, Demo and Real Money Roulette
Most RNG roulette titles ship with a free-play mode that runs on the same maths as the real-money version, just with fake credits. That makes free play the best place to learn a new variant or test a staking pattern without any cost. Live tables do not offer free play, because the croupier is streamed in real time.
What Free Roulette Is Good For
Free roulette is for learning, not for profit. Use it to familiarise yourself with the layout, practise placing call bets on a racetrack, and experiment with variants you have not played before (French roulette, for example, behaves differently on even-money bets from its European cousin). The maths behind the free version is identical to the real-money version, so any pattern you learn carries over directly to a stake-funded session.
Simulators for Strategy Practice
Dedicated roulette simulators go a step further than free play. A simulator runs thousands of spins in seconds, showing how the Martingale, Fibonacci, or flat-betting approaches actually behave over a long run. The result is usually an education in variance, not in edge, and simulators cost nothing to run.
When Real Money Roulette Makes Sense
Switch to real money once you are comfortable with the layout, the bet types, and the pace of your preferred table, and once you have a bankroll you can comfortably risk for entertainment. Start at the lowest stakes, keep a loss cap, and focus on the quality of each session rather than any single spin.
Play Responsibly
Roulette is entertainment, not an income source. Please gamble responsibly and only with money you can afford to lose. Gambling is for adults only, 18+, and gambling laws vary by jurisdiction so check your local regulations before playing. If you feel gambling is becoming a problem, reach out to a recognised support organisation in your country for confidential help.
- Set a loss cap before every session and walk away when it is reached
- Treat every wager as money already spent on entertainment
- Never chase losses by raising stakes
- Take regular breaks and keep sessions short
- If play stops being fun, stop playing and talk to someone you trust
Frequently Asked Questions About Roulette
How do you play roulette?
Place chips on the betting grid for inside bets (specific numbers), outside bets (red or black, odd or even, columns, dozens), or call bets on the wheel racetrack. The croupier spins the wheel and releases the ball in the opposite direction, and once the ball settles in a numbered pocket the winning bets are paid at fixed ratios. Every bet carries the same house edge for a given wheel, so the bet you choose changes the variance of your session, not the long-run expectation.
What are the payouts in roulette?
A straight-up bet on a single number pays 35 to 1. A split pays 17 to 1, a street pays 11 to 1, a corner pays 8 to 1, and a six-line pays 5 to 1. Outside bets pay 2 to 1 on columns and dozens, and 1 to 1 on red or black, odd or even, and low or high. These payouts are the same across European, American, and French wheels. What changes with the wheel is the probability of hitting, not the payout ratio.
What is the difference between European and American roulette?
A European wheel has 37 pockets with a single green zero and a house edge of 2.70 percent on every bet. An American wheel has 38 pockets with an additional double-zero pocket, which pushes the edge to 5.26 percent on every bet and a particularly bad 7.89 percent on the five-number top-line bet. The payouts are identical, the probabilities are not. Always choose a European wheel over an American wheel if both are available, because the double zero roughly doubles how fast the house takes its share.
What is En Prison and La Partage?
Both are French rules that soften the blow of a zero result on even-money outside bets. La Partage returns half the stake immediately when the ball lands on zero. En Prison locks the losing stake for one more spin, and if the next spin wins, the stake is released back (no profit, no further loss). Either rule cuts the house edge on even-money bets from 2.70 percent to 1.35 percent, which is the lowest edge in mainstream roulette. Any French roulette table in a good lobby applies one or both of these rules.
Can you actually win at roulette with a strategy?
In the short term yes, over the long run no. Every spin is independent of the last, and the house edge is baked into the presence of the zero pocket. Betting systems like Martingale, Fibonacci, and D’Alembert change how variance feels in a session, but none of them remove the zero from the wheel or shift the expected return. A disciplined approach to bankroll and session length preserves your session, but no staking pattern beats the maths of the wheel.
How does the Martingale system work?
Martingale doubles the stake after every loss on an even-money bet (red or black, odd or even, low or high). The logic is that the first win recovers all prior losses and adds one base unit of profit. In practice the system runs into two limits very quickly, the table maximum and the size of your bankroll. A losing streak of seven or eight is uncommon but not rare, and it is enough to exhaust either limit. Martingale feels safe until the streak arrives, at which point the losses are far larger than any flat-betting session would have produced.
What is the difference between live and online roulette?
Live roulette streams a real croupier at a real wheel, with broadcast-grade production and a shared table across many online players. RNG roulette is simulated by software, instant and solo, with a new spin available on demand. Both can run European, American, French, or game-show variants. Live tables feel closer to a land-based casino, RNG tables play faster and support lower stakes. The wheel decides the edge, the format decides the experience.
Which roulette variant has the lowest house edge?
French roulette with La Partage or En Prison carries the lowest edge in mainstream play, at 1.35 percent on even-money outside bets. European roulette is next at 2.70 percent on every bet. American roulette is the worst of the standard three at 5.26 percent, because of the double-zero pocket. Game-show variants like Lightning and Quantum sit slightly higher than European at around 2.90 to 3 percent, because the boosted multipliers are paid for by shorter ratios on unboosted straight-up wins.
Can I practise roulette for free before playing for money?
Yes. Most RNG roulette titles include a free-play mode with fake credits and identical maths to the real-money version. Online roulette simulators are another option, and they are especially useful for stress-testing a staking system across thousands of spins in seconds. Both are the fastest way to get comfortable with the layout, the bet types, and the pace of your preferred variant before risking a real bankroll.
