Most casinos that offer online roulette do not develop their own games, with very few websites using proprietary software. Instead, they rely on the expertise of third-party vendors that specialize in software development.
Companies like Playtech, Evolution Gaming, NetEnt, and Microgaming have single-handedly changed the way we perceive roulette, transforming it from a landbased casino classic to a digital game we can enjoy from the comfort of our surroundings.
Most roulette variations you can play online are developed by these heavy hitters of the gambling industry. Online casinos purchase their roulette games from these vendors on a B2B (business-to-business) basis.
The developers are responsible for the games’ infrastructure, the platforms, and the streams of live-dealer roulette variants. Some software studios even provide back-office solutions that enable online casinos to track customers’ play, manage their support service, and exercise effective marketing.
What we intend to do next is provide you with a detailed guide on the best suppliers of online roulette in the world, explaining why these companies are worth their salt. We also feature concise information on some of their top roulette creations and answer the most common questions fans of the game might have.
Categories of Roulette Games You Can Play Online
Online players are facing such a great versatility they sometimes end up getting lost in the myriad of roulette variants available on the web. There are all kinds of options ranging from Playboy Roulette with gorgeous dealers in scant clothing to Pinball Roulette, which is a combination of classic roulette and a pinball machine.
With such a vast choice, it is sometimes difficult to make a neat categorization but we will do our best. We are of the opinion online roulette games can be classified into three main categories based on graphics quality and how the spin outcomes are determined.
Some roulette variants rely on RNG software for the results while others are governed by professional human dealers. RNG and live dealer roulette games are so vastly different that some software vendors focus specifically on one or the other.
But before we proceed any further, we would like to throw in a brief explanation on how randomness is ensured at online and landbased roulette tables.
RNG Outcomes vs. the Randomness at Landbased Tables

Progressive Roulette RNG Outcomes vs. the Randomness at Landbased Tables
The outcomes of roulette spins in landbased casinos are governed by a set of physical parameters such as ball and wheel speed of rotation, friction, air resistance, and gravity. Minuscule wheel defects can result in biases, which, in turn, lead to a certain level of predictability of results.
Landbased casinos go out of their way to guarantee random outcomes. They are quick to detect and remove non-random wheels from their floors.
From a purely theoretical perspective, one can “predict” the ball’s drop zone provided they can measure and analyze all of the above-mentioned forces. Players, however, lack the instruments that would allow them to make such precise measurements and arrive at 100% accurate predictions.
Landbased roulette is random in this context, which simply means the results are immeasurable to such a great extent that we might as well consider them completely unpredictable. The frequent dealer rotation further contributes to the futility of this task.
In contrast, online roulette relies on software programs that generate random numbers to determine the results of spins. These programs are tirelessly spewing long number sequences which are then converted into a graphical representation of the things the player sees on their desktop or mobile screen.
The RNG software relies on highly complex algorithms to determine where the ball will land. Technically speaking, the RNG is incapable of generating completely random numbers. However, the algorithms it uses are complex enough to make it impossible for a person to discern any measurable patterns.
The number sequences are different each time because they result from random seed numbers. This guarantees the unpredictability of the outcomes in online roulette games. Furthermore, the casinos’ software is regularly tested by independent specialists who ensure the RNG embedded in the games consistently picks numbers on a random basis.
If the software has not been tampered with, the RNG-based roulette games arrive at their expected payout percentages with large enough outcome samples.
3D Roulette Governed by RNG
Such roulette games ensure a highly immersive experience despite the fact they lack a human element in the form of a live dealer. They boast three-dimensional graphics making it possible for players to discern even the tiniest details at the virtual table.
The shiny wheels are exact replicas of those used in landbased casinos, so much so that you forget you are playing against a software at some point. This detailed visual presentation in combination with immersive ambient sounds makes for a highly realistic experience.
The intuitive interface makes it easy for players to size their bets and post chips on the layout. Similarly to landbased roulette, the 3D online variations are equipped with scoreboards, allowing trend bettors to track past results.
Information about table coverage, result distribution, and racetrack betting are available as well. Some 3D variations even enable superstitious players to change the rotation direction of the wheel.
Pros and Cons of 3D Roulette Games
They are available with demo credits or for real money
They lack the social interactivity of the landbased roulette tables.
The player can control the dynamics of the gameplay and determine the time between spins.
Online gambling on roulette and other fixed-odds games is illegal in some jurisdictions.
The table minimums are usually lower than those in landbased casinos.
Most online casino bonuses have higher wagering requirements for roulette or exclude it altogether from bonus play.
There is no need to comply with table etiquette.
Live Dealer Roulette
Unlike RNG-based roulette, live roulette plays on an actual physical wheel, with a dealer who spins the ball and verbally announces the results. The action takes place either in a traditional landbased casino or in a dedicated studio with a unique setting for each live roulette table.
The gameplay is transmitted in real time with the help of multiple cameras that stream what happens at the table in real time. The player uses the gaming interface for bet sizing and posting. After the dealer declares the result, the software pays winning players at the standard roulette odds.
You have a choice from several camera angles as well as the opportunity to chat with the dealer and the other players. Some suppliers of live software like Ezugi give you the chance to tip the dealers just like you would at the landbased roulette tables.
The developers are responsible for all aspects of the live games’ operation, from creating the user interface to providing the live stream and designing the live tables’ settings.
Pros and Cons of Live Dealer Roulette
More social engagement and interaction
Not much time to place bets between spins
Multiple cameras at the live tables
Requires faster and more stable internet connection to prevent lags and stream buffering
Diverse table limits that fit into the needs of all players
Some tables are not in operation around the clock
Friendly and attractive dealers that keep you invested in the gameplay
Not available for play with demo credits in most cases
Progressive Roulette
Progressive jackpots in landbased casinos are often exclusively reserved for slot players. This is not the case at online casinos as some software suppliers have developed roulette games attached to progressive jackpot networks.
These jackpots grow incrementally because a small percentage of each stake goes toward the progressive prize. The latter continues to escalate, sometimes going into the seven-figure mark.
Some progressive variations like Playtech’s Age of the Gods Roulette feature multiple-tier jackpots where players can win one out of several prizes. In Playtech’s progressive roulette games, the prizes can hit randomly on any spin of the wheel. A random bonus game starts where players are guaranteed to win one of the progressive pots.
Microgaming, another heavy hitter when it comes to online casino software, also gives fans of the wheel-based game the chance to win big with Roulette Royale. The difference here is that the player must place the $1 Jackpot Side Bet if they want to stand any chance of collecting the prize. The jackpot drops when the same single number hits five times in succession.
Pros and Cons of Progressive Roulette
Roulette players are given the chance to win enormous jackpots.
In some progressive variants, you need to post a side bet on each spin just to qualify for the chance of winning the massive prize.
Some progressive roulette games have random prizes so there is no need to spend extra on jackpot side bets.
The odds of winning the pot in some variants are astronomically small because single numbers must hit repeatedly in succession.
Players with previous roulette experience face no difficulties with the progressive variants because they play according to the standard rules of the game.

Ezugi’s roulette catalog is not as rich as that of Evolution but they still boast a decent variety of options. Some of the games are broadcast from the floors of the Maltese casinos Portomaso and Oracle.

Versatility is Key – The Studios with the Largest Online Roulette Collections
Playing common variations like American, French, and European roulette tends to get repetitive and boring over time. You can diversify your roulette experience by signing up with online casinos that use the services of older software suppliers like Microgaming and Playtech.
Both companies boast significant experience in the gaming industry and are not afraid to stray off the beaten path, delivering original variations that completely change the way roulette plays. These suppliers have greatly expanded their gaming suites over the years and currently offer the most comprehensive roulette selections you can find online.

Playtech discloses information about its games’ theoretical return to player percentages and gives roulette players a choice from two main options – instant play and downloadable software.
The roulette games created by Playtech impress with a neat design, sleek visuals, and customization options like changing the color of the table baize, the view angle, and the wheel’s direction of rotation.
The studio offers the standard set of double-zero and single-zero roulette versions in addition to a variety of unconventional options such as Multi-Wheel Roulette, Pinball Roulette, and Mini Roulette.

Microgaming
Being one of the oldest suppliers of quality gambling software in the world, Microgaming boasts the most comprehensive selection of roulette variants, and casino games in general, with more than 800 options.
Microgaming’s story started in 1994 when the company launched the first gambling site in the world, the Gaming Club, which continues to operate and use its software to this day. Unfortunately, the company withdrew from the US market in 2008 due to the country’s anti-online gaming laws.
The world-renowned supplier has so far released 10 or so roulette variants, including the conventional set of European, French, and American Roulette from its Gold Series. The graphics in some in some of the older releases are not as sophisticated but the games compensate with playability and well-designed interface.
The French variations offer the La Partage rule where players receive half of their losing even-odds bets back when zero shows. In one variant, players have the option to activate and bet on up to eight wheels.
The multiplayer variation brings a social element into RNG roulette thanks to its interactive chat facility. Below is concise information about the Microgaming varieties we found the most appealing.
