A true casino mainstay, roulette has dominated gambling halls worldwide for centuries. Today, the game is available to players at the click of a mouse at hundreds of online casinos, where it comes in a variety of enticing forms, some traditional and others new and unconventional.
That is why we at BonusInsider created this page. Here, we share our knowledge of roulette, including its rules and the bet types it supports. We also introduce our readers to the top software vendors that supply roulette games to trusted online casinos.
On this page, you’ll discover the best variations of this iconic game available online. We also explain the most popular betting systems used at both online and land-based roulette tables. Let’s begin with a brief overview of roulette’s key rules.
How to Play Roulette
1Place Your Bets
Roulette is a classic game of chance in which players have no influence over the outcome of a given coup. The game is played on a wheel that has either 37 or 38 pockets, containing numbers 0 through 36 (plus 00 in double-zero games). The player’s goal is straightforward: to win a coup, they must predict where the small white ball will land on the wheel.
A round begins when players place their chips in the corresponding betting boxes on the layout. In roulette, you can wager on individual numbers, groups of numbers, or number properties such as color or parity.
2Spin The Wheel
Once bets are placed, the croupier determines the winning number and its color by tossing the ball in the direction opposite to that of the spinning wheel. Some wheels are spun manually by croupiers, while others use rotors designed to produce random results.
3The Outcome
Several additional factors help randomize the outcome of this game of chance. A roulette wheel features alternating red and black pockets. The numbers inside them are not arranged from lowest to highest. Instead, they follow nonsequential arrangements that differ between single-zero and double-zero wheels.
Additionally, deflectors known as diamonds line the inner rim of the wheel and cause the ball to bounce unpredictably. The ball gradually loses momentum due to friction and finally settles in one of the 37 or 38 pockets, determining the result.
The croupier then settles the bets, pays the winners, and removes the losing chips from the table layout. A new coup can then begin.
Roulette Bets
Before we proceed any further, we would like to warn you that there is no way to change the odds of winning in this game. The odds of any given number hitting always remain the same – 1 to 35 on single-zero wheels – because roulette is based on independent trials; that is, the past does not impact the future, and previous results have no effect on the outcomes of subsequent spins.
With that out of the way, let’s look at the main categories of roulette bets. Check them out below, along with the payouts they offer when luck smiles upon you.
Inside BetsOutside Bets
The chips used for outside bets are placed in the designated outside-bet area of the cloth-covered layout. This category includes several wagers that cover entire groups of numbers or number properties, such as parity and color. These bets offer higher chances of winning but come with lower payouts.
- Bets on number properties such as red/black, odd/even, and high (19 through 36)/low (1 through 18) pay even money (1 to 1) and lose when the ball settles in the green zero pocket unless the La Partage or En Prison rule is in effect.
- Column bets comprise three groups of 12 numbers each, positioned in the vertical columns on the table layout. For example, a bet on the middle column covers numbers 2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, and 35. A winning column bet pays 2 to 1. It loses when zero hits, as neither 0 nor 00 belongs to any of the three columns.
- Dozen bets cover 12 numbers, as the layout is divided into three dozens. The first dozen contains numbers 1 through 12, the second spans numbers 13 through 24, and the third covers numbers 25 through 36. Under each dozen is a betting box where you place your chips. The boxes are labeled 1st 12, 2nd 12, and 3rd 12, respectively. These bets pay 2 to 1 and also lose when zero hits.
- The snake bet comprises the following 12 numbers: 1, 5, 9, 12, 14, 16, 19, 23, 27, 30, 32, and 34. It gets its name from the zigzagging pattern these numbers form on the layout. This bet is not available at all roulette tables, but when it wins, it pays 2 to 1.
Inside Bets
Inside bets are placed either on individual numbers or on combinations of multiple numbers. The chips for these wagers are placed in the central area of the layout, which contains the numbers 0 through 36. You place your bet either in the box corresponding to a single number or at the intersection of your chosen numbers. Inside bet combinations can consist of two to six numbers.
- The straight-up bet is the highest-paying wager in roulette. It is placed on any single number from 0 through 36. If your number hits, you collect 35 chips for every chip you have staked.
- A split bet covers two numbers of your choice. Chips for split bets are placed on the line that divides two adjacent numbers on the table layout, such as 6/5, 6/9, or 8/11. A winning split bet pays 17 to 1.
- A street bet covers three consecutive horizontal numbers, such as 1, 2, and 3; 4, 5, and 6; or 7, 8, and 9. Chips are placed on the outer border of the first number in your chosen row. When the ball lands on any of the three numbers, your street bet wins at odds of 11 to 1.
- The double street bet covers six consecutive numbers positioned in two neighboring rows on the layout, such as 1, 2, 3, 4, 5, and 6. With this bet, you place your chips at the intersection of the two rows. It pays 5 to 1.
- The corner bet covers four numbers whose boxes on the layout share a common corner, such as 1, 2, 4, and 5. You place the chips at the point where the horizontal and vertical lines of the betting boxes intersect. You receive a payout of 8 to 1 if any of your four numbers hits.
- The basket bet covers zero and the numbers 1, 2, and 3 in single-zero variations of the game. With this wager, you place your chips at the intersection of 0 and 3 or 0 and 1. This bet offers the same payout as the corner bet, 8 to 1, and wins if the ball lands on 0, 1, 2, or 3. A similar bet is available on double-zero tables, where it covers five numbers: 0, 00, 1, 2, and 3.

NetEnt is a leading Swedish software studio founded in 1996. This vendor may not offer as broad a range of roulette options as the previous two suppliers on our list, but its games emphasize gameplay, compatibility, and graphics. NetEnt’s most popular variants include American, European, and French Roulette, as well as Roulette Advanced.
Betsoft
Betsoft is a European online casino software developer that specializes primarily in 3D slots. However, the studio has also released several roulette variations notable for their playability, visuals, and intuitive interfaces. Examples include Betsoft’s Zoom Roulette and Common Draw Roulette.
Roulette Variations
There are dozens upon dozens of roulette variations available online for both real-money play and practice. This can make it difficult for anyone to separate the wheat from the chaff, especially if they lack experience playing the game online. We have tested virtually every roulette variant imaginable, so trust us when we say these are the six must-try variations every die-hard fan should play.
Multi-Wheel Roulette
Progressive Roulette
Double Ball Roulette
Spread Bet Roulette
Mini Roulette
Common Draw RouletteMulti-Wheel Roulette
Multi-Wheel Roulette is one of the less conventional versions of roulette available online. There are two distinct variants. The version provided by Microgaming uses eight wheels that you can activate and play simultaneously, while the Playtech version features six wheels. Each wheel you activate requires an additional bet, so keep that in mind.
Progressive Roulette
Progressive jackpots are no longer reserved exclusively for slot players. Roulette fans can also win a pooled jackpot prize through progressive roulette variations developed by Microgaming and Playtech. Large pots can be won in Roulette Royale, Frankie Dettori’s Jackpot Roulette, Dragon Jackpot Roulette, and Age of the Gods Roulette. Some variants require you to place a small optional side bet to qualify for the pot.
Double Ball Roulette
Double Ball Roulette uses two balls instead of one. Software supplier Felt has produced a variant in which even-money bets win when both balls land on the same outcome. The game supports unconventional wagers such as Red and Black, which pay even money when one ball lands on each color. If both balls land on the same color, the payout is 3 to 1.
Spread Bet Roulette
Playtech’s Spread Bet Roulette stands out because it offers a wider range of betting options. This is made possible by a gilded inner wheel, which lets you place side bets and potentially win up to 400 times your initial stake.
Mini Roulette
Mini Roulette is another Playtech creation that differs from the traditional version of the game. It follows the same rules but is played on a smaller table layout and uses a wheel containing only the numbers 0 through 12. The payouts for straight-up, split, corner, and dozen bets are reduced to account for this difference.
Common Draw Roulette
Software provider Betsoft has added a social element to online gaming with the introduction of Common Draw Roulette. This multiplayer version includes a chat box that lets you talk with other participants. Because of this feature, you have 32 seconds to place a new bet between spins.
Roulette Strategies
Тhe Martingale
The Fibonacci
The D'Alembert
The Labouchere
The Parlay
The Martingale is one of the most commonly used systems at roulette tables. Also applicable online, it is a negative betting progression that requires you to double your wager after each loss and return to your base unit after a win. It is based on the idea that a win following a losing streak can recoup the previous losses. The aim is to finish with a profit of one base unit when the losing streak ends.
View more...The Fibonacci system is another negative progression that can expose your roulette bankroll to significant risk. You increase your wager after a loss according to the Fibonacci sequence, in which each consecutive number equals the sum of the previous two: 1, 1, 2, 3, 5, 8, 13, 21, and so on. Both this system and the Martingale are predominantly used for outside bets that pay even money.
View more...The D’Alembert is another negative progression designed for even-money bets. The progression is more gradual, so stakes rise more slowly. You start with a base bet of your choice and increase your stake by one unit after each loss. Consequently, recouping your losses during longer losing streaks is a slower process with this system.
View more...The Labouchere is one of the more complex systems and, as such, may be unsuitable for roulette beginners. Also called the cancellation system, it is recommended for even-money wagers. First, you decide on a win goal and convert this sum into base units. Suppose your goal is $100, which corresponds to ten base units of $10 each. You then write a sequence of numbers, such as 1, 2, 3, 4, 3.
Your first stake is the total of the first and last numbers, or $40 in this case. If you win, you cross these numbers out of the sequence and bet $60 next. If you lose, you add the stake, which is the sum of those two numbers, to the end of the sequence and wager that amount on the next spin. Once you reach your win goal, all the numbers in your sequence will be crossed out.
View more...The Parlay strategy requires you to first decide how much you want to win. Each time you record a win, you wager both your profit and your original stake on the next coup. For example, if you start with $10 on red and it hits, you place $20 on the next spin. This process continues until you reach your target profit for the session. If you lose a coup, you return to flat betting until you record another win.
View more...Oscar’s Grind is a roulette system that uses a betting progression that is neither positive nor negative. The idea is to keep your bets low during losing rounds and increase them once a favorable streak begins.

How is randomness ensured in online variations of roulette?
We have already discussed how casinos ensure randomness in land-based variants, but what about online roulette? Online outcomes are governed by a Random Number Generator (RNG). It generates random multidigit numbers, which are then mapped to one of the 37 or 38 pockets on the wheel. The RNG is designed to ensure that online games deliver random results and the expected long-term theoretical return.
This is my first time playing roulette online. Can I first try the games without risking my money?
Yes, most online casinos that offer the game give customers the option to play in practice mode with free demo credits. If you exhaust your demo bankroll, simply reload the game and you will start with the same amount. UK players who want to try roulette for free at UKGC-licensed casinos must first sign up and verify their accounts before practice mode becomes available.
Should I play single-zero or double-zero roulette?
Seasoned roulette enthusiasts favor single-zero tables because these games have a smaller house edge. In roulette, the house gains its edge through the addition of the zero pocket. Without zero, bets based on number properties such as color or parity would offer even chances. The house edge on single-zero tables is 2.70% or 1.36% with La Partage or En Prison. Adding the 00 pocket to a double-zero wheel almost doubles the house edge, increasing it to 5.26%.
