What is Online Roulette?

Roulette remains one of the most iconic games in gambling, its spinning wheel as familiar online as it is in a Mayfair casino or an Atlantic City hall. In 2025, the game has firmly adapted to mobile apps and online platforms. Whether streamed live with human croupiers or run via Random Number Generators (RNG), roulette continues to attract players for its mix of simplicity and drama.

UK-licensed operators such as Bet365 Casino, The Vic Casino, Rialto Casino, and Jackpotjoy run both live and digital tables. In the U.S., state-regulated casinos including BetRivers, BetMGM, PlayStar, and Fanatics Casino carry multiple roulette variants, each with distinct RTPs and betting options.

The shiny, gleaming silver ball. The spinning wheel that determines your fortune. And the anticipation of the outcome. There are many reasons why roulette is among the most popular table games played in online casinos in the USA. Remember that roulette is 100% a game of luck. Skill and strategy really play no role in the outcome.

How Roulette Works

To start out, you’ll be placing your chips on the squares on the numbered layout of the roulette table. Inside bets are placed on numbers or groups of numbers around the inside of the table.

Outside bets are placed on red or black numbers, odd or even numbers, or groups of numbers that surround the outside of the table.

When the croupier declares, “no more bets” they set the ball to spinning and when it lands, everyone discovers who’s a winner.

The three most common forms of roulette are American, European and French. European and French roulette both include numbers from 1-36, as well as zero. In French roulette, landing on zero results in half of your 50-50 bets being refunded.

American roulette includes both zero and double zero on the wheel. As a result, the odds of winning lengthen from 35-1 to 37-1. 

Before You Start: Basic Rules of Roulette & House Edge

Roulette is a game that’s played on a large spinning wheel with 38 numbered pockets, each of which is either red or black. The numbers on the wheel range from 1 to 36, with a 0 and a 00 thrown in for good measure.

The game is played by betting on where the ball will land when the wheel stops spinning.

Players can place their bets on individual numbers, groups of numbers, or on the color of the pocket where the ball will land.

Once all the bets have been placed, the dealer spins the wheel in one direction and throws the ball in the opposite direction. As the ball slows down, it will eventually come to rest in one of the pockets, and the dealer will announce the winning number and color. Players who bet on the winning number or color are paid out according to the odds of their bet.

Let’s just include a few words here about house edge. Every roulette variant has an in-built house edge, which determines the average payout made to players.

For example, European Roulette has a house edge of 2.7%. That means for every $100 bet, $2.70 is taken by the casino. That’s the long-term average over millions of spins.

In American Roulette, however, the house edge increases to 5.26%. That’s because the game features an additional green pocket – 00 – which makes it harder to hit your Red/Black wagers.

RTPs and Payout Structures

Roulette payouts depend on the type of bet placed. Inside bets cover fewer numbers but pay higher multipliers, while outside bets cover larger groups with smaller returns. The table below shows the standard payout structure used in online and land-based casinos:

This structure highlights the trade-off between risk and reward: a straight-up bet on a single number offers a 35:1 payout but comes with long odds, while outside bets like red/black offer nearly 50/50 chances at even money.

On a European wheel (single zero), red wins 18/37 ≈ 48.65% of the time. An even-money bet has expected value (EV):

EV = +1×1837+1 \times \frac{18}{37}+1×3718​ − 1×19371 \times \frac{19}{37}1×3719​ = −137-\frac{1}{37}−371​ ≈ −2.70%.

In plain terms, a $10 bet on red loses about 27¢ per spin on average; over 100 spins, roughly $27.

On an American wheel (double zero), red wins 18/38 = 47.37%. The same even-money bet’s EV is:

EV = +1×1838+1 \times \frac{18}{38}+1×3818​ − 1×20381 \times \frac{20}{38}1×3820​ = −238-\frac{2}{38}−382​ ≈ −5.26%.

So a $10 bet on red loses about 53¢ per spin on average; over 100 spins, roughly $53.

The pattern holds for inside bets too. A straight-up online roulette bet pays 35:1.

• European: win prob 1/371/371/37. EV = 35×137−1×3637=−13735 \times \frac{1}{37} – 1 \times \frac{36}{37} = -\frac{1}{37}35×371​−1×3736​=−371​ ≈ −2.70%.
• American: win prob 1/381/381/38. EV = 35×138−1×3738=−23835 \times \frac{1}{38} – 1 \times \frac{37}{38} = -\frac{2}{38}35×381​−1×3837​=−382​ ≈ −5.26%.

Bottom line: the payout table is identical, but the extra 00 pocket on American wheels doubles the house edge, turning the same bets into noticeably worse value over time.

Popular Online Roulette Variants

European Roulette

European Roulette is the most widely offered version online, particularly in the UK. It uses 37 pockets: numbers 1–36 plus a single zero. The house edge is 2.7%, which translates to an RTP of 97.3%. This makes it more favorable than its American counterpart.

For instance, at Rialto Casino, players can wager as little as £0.20 per spin on European Roulette. Bet365 Casino UK features both RNG and live versions, with streamed tables allowing bets from £1 to £500. The single-zero format appeals to players who want competitive odds without the added risk of a double zero.

American Roulette

American Roulette, common in U.S. casinos, adds a double zero pocket, creating 38 slots in total. The extra pocket increases the house edge to 5.26%, or about 94.74% RTP. While it is statistically less favorable, it remains popular because of its long tradition in U.S. casinos.

On apps like BetRivers NJ and Hard Rock Bet, American Roulette is the default variant. Casual players often start with $1 chips, while higher-stakes tables allow wagers up to $2,000 per spin. It’s often bundled with promotional offers, such as deposit matches or free-play credits, which offsets the less generous odds for some players.

French Roulette

French Roulette is the most player-friendly form, though it is less common online. It uses a single-zero wheel like European Roulette but adds special rules such as La Partage and En Prison. If the ball lands on zero, half of the player’s even-money bet is returned (La Partage) or carried over to the next spin (En Prison). This reduces the house edge on even-money bets to just 1.35%, making it highly attractive.

UK casinos like The Vic occasionally feature French Roulette as part of their live dealer lineups. In the U.S., BetMGM includes French Roulette in premium tables, especially for high rollers. For example, a $50 bet on red, if lost to a zero, may return $25 under the La Partage rule, softening the blow considerably.

Live Dealer Roulette

Live dealer roulette has become the dominant online format, particularly on mobile apps. Powered by developers such as Evolution Gaming and Playtech, these tables are streamed from professional studios. Multiple camera angles, real-time dealer interaction, and chat features make the experience similar to playing in a physical casino.

Games like Lightning Roulette add multipliers of up to 500×, randomly applied to straight-up numbers. At Casumo UK, a player betting £2 on number 7 could see a payout of £1,000 if the multiplier hits. In the U.S., DraftKings Casino runs live roulette studios tied to its sportsbook app, allowing players to switch between bets seamlessly.

Bonus Ball Roulette

Developer: IGT

IGT produces several online roulette variants with bonus pockets. Double Bonus Spin Roulette is available at Golden Nugget and gives you an additional bet – the yellow B pocket. You bag a free spin on the bonus wheel if you win on yellow.

100/1 Roulette

Developer: NYX Gaming

100/1 Roulette is the perfect example of a table game you can only find online. The RTP (92.86–96.19%) is a little lower than the return you’ll see in regular European Roulette. However, there’s a lot more action as the game lets you bet any one of 105 possible outcomes.

Roulette Strategies

Martingale System

The Martingale system is the most talked about. Roulette online players double their stake after every loss on an even-money bet (e.g., red/black).

At Bet365 Casino, a player starting with £1 on black could lose five times in a row and be betting £32 on the sixth spin. If that wins, all losses are recovered plus £1 profit. The risk is obvious: hitting table limits or running out of funds quickly.

If you play online roulette in the USA, at bet365, for example, and bet $10 and lose, you would then bet $20 on the next spin. If you lose again, you would bet $40, and so on. The idea is the same – that eventually, the you will win and recoup their losses.

Reverse Martingale (Paroli)

The Reverse Martingale, or Paroli Roulette system, flips the logic: players double after wins instead of losses. At BetRivers, someone starting with $5 on red might increase to $10 after a win, then $20, letting streaks compound profits. The risk is smaller bankroll drain, but winning streaks rarely last long.

Flat Betting

Flat betting in online roulette means placing the same stake every spin, often $1 or £1. Many casual players at Jackpotjoy UK or FanDuel Casino prefer this, as it stretches their session time and limits exposure. It doesn’t promise profits but avoids the steep swings of Martingale approaches.

Combination Betting

Combination betting spreads chips across inside and outside bets. A player might place £5 on red, £2 on 17, and £1 splits around 14 and 18. At Rialto Casino, such play balances the low returns of even-money bets with the higher payouts of single numbers. Apps make this easier by calculating total bets instantly.

High Roller Approaches

At Evolution’s Salon Privé Roulette, stakes can range from £500–£5,000 per spin in the UK or $2,000+ in the U.S. High rollers often combine flat betting on even-money outcomes with occasional straight-up number bets, aiming for stability with the chance of big payouts. BetMGM’s private tables in New Jersey cater to this audience.

The James Bond Roulette Strategy

It is a combination of bets that covers more than half of the Roulette table. The player bets $140, with $50 on the numbers 19-36, $50 on the numbers 13-18, and $10 on the zero. This strategy offers a high chance of winning, but the payout is relatively small.

The D’Alembert Strategy

It is a betting strategy where players raise their bet by one unit after a loss and decrease it by one unit after a win. For example, if a player bets $10 and loses, they would then bet $11 on the next spin. If they win, they would gamble $10 on the next spin.

The Fibonacci Method

This is based on the Fibonacci sequence, where each number is the sum of the two preceding numbers (1, 1, 2, 3, 5, 8, 13, 21, 34, etc.). In this strategy, players increase their bet after a loss based on the Fibonacci sequence. For example, if a player bets $10 and loses, they would then bet $10 again. If they lose again, they would bet $20 (the sum of the previous two bets), and so on.
