Top Software Providers in 2024


NetEnt was established in 1996 and has become a standout name among online casino software. This Swedish studio is celebrated for revolutionising slot games with captivating graphics and innovative gameplay. Titles like ‘Starburst’ and ‘Gonzo’s Quest’ exemplify their commitment to immersive experiences; the latter was where they first launched the massively popular avalanche reels mechanism.

They really know how to blend artistic flair with cutting-edge technology, and beyond slots, they’ve got their hands in table games and live casino offerings as well. Their games are among the most popular at 100s of top online casinos, and their consistent focus on innovation and quality has garnered numerous industry accolades. 


Founded in 1999, Playtech has grown to become one of the most prominent figures in the online gambling industry. They stand out for their ability to provide a comprehensive gaming experience and cater to a wide array of player preferences, and it’s all optimised for mobile play. Playtech’s portfolio includes online casino games, live dealer games, sports betting, and even bingo platforms.

A key highlight of Playtech’s offerings is their series of branded slot games. This includes a notable collaboration with Marvel Comics, resulting in a popular series of superhero-themed games. Playtech has also made significant strides in the live casino space, offering high-quality live gaming experiences with professional dealers. Their software is known for its user-friendly interface and reliability, ensuring smooth gameplay across various platforms.


This game company is a true pioneer in the online casino world. It’s one of the oldest established brands, having been around since 1994. Microgaming has since built a reputation for creating some of the most influential games in the industry, with more than 800 titles so far. Their most significant highlight is their progressive jackpot network, which includes the famous ‘Mega Moolah’ slot.

Their vast and diverse portfolio offers everything from slots to table games, live dealers and more. Microgaming is also a trailblazer in embracing new technologies and trends. They were among the first to develop games specifically for mobile devices, recognizing early the shift towards mobile gaming. Their commitment to innovation extends beyond game development. They were instrumental in establishing eCOGRA (e-Commerce and Online Game Regulation and Assurance) and setting standards for fairness and responsible gaming.

Pragmatic Play

Pragmatic Play is one of the newer game companies. Launched in 2015, the company quickly made a name for itself in the competitive online casino industry thanks to a diverse and high-quality portfolio of games with vibrant graphics, engaging themes, and innovative features. Titles like ‘Wolf Gold’ and ‘The Dog House’ highlight their creative approach to game design.

Players are always eager for new games, and Pragmatic Play satisfies this demand with a rapid release schedule, consistently launching new and exciting games.

Real Time Gaming

Real Time Gaming (RTG) has an extensive range of slot games where they display their talent for classic designs and straightforward gameplay. They provide fantastic traditional three-reel slots as well as more complex, multi-line video slots, appealing to a broad spectrum of players.

One of the defining features of RTG is their ‘Real Series’ slots, a collection of games renowned for their random jackpots, which can be won at any time, regardless of bet size or game outcome. Their games are highly customisable, and the flexible software designs mean that different casino operators can adjust game settings to fit their audience preferences. Since 1998, RTG’s consistent presence has shown that they’re a competitive player within the market. 


International Game Technology (IGT) is a powerhouse in the world of casino gaming, both online and offline. Initially gaining fame in land-based casinos with their iconic slot machines, IGT successfully transitioned into the online sphere, bringing with them decades of expertise. They are celebrated for converting their popular physical slot machines into online versions, allowing players to enjoy classic titles like ‘Cleopatra’ and ‘Wheel of Fortune’ from anywhere.

Having been a key player in the gaming industry since 1975, they’re not only well versed in slots. They also power lottery games, digital table games, and sports betting platforms. IGT’s games are not only entertaining but also offer the highest standards of quality, integrity, and fair play.


Novomatic is another industry giant renowned for its extensive history in both land-based and online casino gaming. Originating in Austria back in 1980, Novomatic initially made its mark with high-quality slot machines for physical casinos. Their transition to the online arena has been marked by the same commitment to excellence, bringing classic casino flair to the digital world.

What sets Novomatic apart is their unique blend of traditional and modern gaming experiences. They are particularly famous for their slot game ‘Book of Ra’, a title that has achieved almost cult status among players for its engaging Egyptian theme and exciting gameplay. Novomatic also emphasises innovation and technology in their game development, ensuring their products are not only entertaining but also meet modern standards of playability and security. Novomatic has the stellar ability to adapt to changing market dynamics while maintaining the quality of their classic offerings. Very few other providers have the same level of skill and enduring appeal.


Betsoft is a name you can’t miss when it comes to slot machines, and they’re particularly renowned for their cinematic 3D slots. Betsoft games provide immersive gaming experiences that are both visually stunning and engaging. Their titles are characterised by rich animations, intricate storylines, and high-quality graphics, much akin to what you might find in a modern animated film.

They’re all about pushing the boundaries of traditional slot gaming. Nearing two decades in the industry following a 2006 launch, Betsoft’s innovation in game development and dedication to creating unique and captivating gaming experiences have solidified their reputation as a forward-thinking and creative force for online casino games.


One developer that has revolutionised live casino gaming is none other than Evolution Gaming. They came onto the scene in 2006 and became the undisputed champions in the realm of live dealer games. Evolution provides authentic and immersive casino experiences from the comfort of your home. Their portfolio includes classics like blackjack, roulette, baccarat, and poker in multiple variations. They also introduced unique live game shows like ‘Dream Catcher’ and ‘Crazy Time’, which blend traditional gambling elements with the entertainment style of TV game shows. And they have eight state-of-the-art studios worldwide from where they stream their high-quality live game offerings.

This company hasn’t only focused on creating games but has had its hands busy with multiple acquisitions. They’re currently the parent company to NetEnt, Big Time Gaming, Red Tiger, Ezugi, and more notable brands.

Play ‘n GO

Striking graphics, innovative gameplay, and engaging themes are constants across Play ‘n GO‘s releases. This company, born in 1997, started out as a subcontractor before becoming an independent company in 2014. They’ve got hundreds of titles under their belt, including a diverse range of slot games and table games like blackjack, roulette and baccarat. Titles like ‘Book of Dead’ and ‘Reactoonz’ showcase their ability to create captivating narratives and characters, making their games more than just a gambling experience.

This developer is known for their attention to detail in game design, including well-composed soundtracks and smooth animations, which together create a highly immersive gaming experience. Among Play ‘n GO’s unique features is the widget games function, which allows operators to embed mini versions of games in banner ads. This not only enhances player engagement but underscores their forward-thinking approach and openness to technology. They consistently deliver innovative and entertaining games and are big on mobile gaming.

Big Time Gaming

Big Time Gaming (BTG), launched in 2011, is among the top innovative forces in the online slots market. A hallmark of BTG is their unique gameplay mechanics like Megaways and Feature Drops. By introducing the Megaways mechanic, which offers an ever-changing number of reels and win ways, BTG has revolutionised the slot gaming experience, providing players with dynamic and unpredictable gameplay.

Their impact on the industry was further consolidated when they licensed the Megaways mechanic to other software providers, allowing the mechanic to be used in a wide range of games and thereby transforming the landscape of modern slot gaming.

Light & Wonder

Previously known as Scientific Games, this company has been a significant player in the gaming and lottery industry since its inception in 1973. They started out as a lottery company and are now revered for their comprehensive range of products covering everything from casino games to sports betting and other digital gaming solutions.

Transitioning from Scientific Games to Light & Wonder marked a strategic shift towards a more focused approach in digital gaming and online gambling for the company. Light & Wonder’s commitment to innovation is also evident in their OpenGaming platform, a cutting-edge digital ecosystem that provides seamless integration and access to a vast library of games for operators. They have a wide range of subsidiaries, including other popular brands like Barcrest, Bally Technologies, WMS Industries, NYX, and more.


Yggdrasil games are highly innovative and visually stunning, and these features have been the hallmark of the developer’s portfolio since going live in 2013. They are based in Malta and specialise in slots, lottery games, and mobile casino games. They stand out by creating games that are not just about gambling but also provide a rich narrative and cinematic experience, an approach which is evident in games like ‘Vikings Go Berzerk’ and ‘Jungle Books’, all featuring detailed graphics, engaging storylines, and immersive soundtracks.

Besides churning out games, Yggdrasil have developed promotional tools like BOOST and Game Engagement Mechanics (GEMS), which enhance player engagement and retention for operators. Their YG Franchise and YGMasters programs enable third-party content creators and game developers access to their product tools and services to develop and distribute games. So, they’re actively focused on growing the online gaming landscape.

Red Tiger Gaming

Founded in 2014, Red Tiger Gaming is a well-recognised slot developer with a knack for creating visually stunning and innovative slot games. They’re a boutique studio and smaller than many others, but they’re a subsidiary of NetEnt, which tells us all we need to know about the quality standard.

A key highlight of Red Tiger Gaming is their Daily Jackpots feature, which guarantees jackpot payouts on a daily basis. This feature has significantly boosted player engagement and excitement, setting Red Tiger apart from other providers. The company has a particular flair for Asian-themed slots, as seen in popular titles like ‘Dragons Luck’ and ‘Lucky Wizard’. There’s also a consistent commitment to high-quality, seamless gameplay across all devices.

What Makes a Good Software Provider

Without games, there wouldn’t be casinos. Bonuses and other features contribute to the excitement, sure enough, but there’s no denying that games are the key to it all. This makes casino software providers the backbone of your gaming experience. Therefore, it’s important to make sure you’ve got the best studios powering your chosen online casino.

Here are some key factors that distinguish the best providers in the business:

Variety and Quality of Games

Top providers offer a wide range of high-quality games and innovative titles that push the boundaries of traditional gameplay. Whether it be slots or classic table games like blackjack and roulette, these games should be defined by excellent graphics, smooth gameplay, and engaging sound effects.

Innovation and Technology

The online casino industry is always evolving, and top software providers must keep pace with the latest technological advancements. The best game companies experiment with new and innovative features to boost interaction and engagement across their games.

User Experience

A good provider understands the importance of user experience. This includes easy navigation, fast loading times, and a clean interface that makes it simple to find your favourite games. With an intuitive design, you can rest assured of enjoying your gameplay without any hassle.

Mobile Compatibility

In today’s world, players enjoy gaming on the go. So, the best software providers create fully optimised games for mobile devices. This means games should run seamlessly on smartphones and tablets, with features and graphics that adapt to fit smaller screens. Software should also be available to play with no download required.

Fairness and Security

Leading software providers must ensure that their games are fair and unbiased. They must use RNGs (Random Number Generators) to guarantee random game outcomes, and the best studios will have their games tested and certified by independent organisations like eCOGRA, BMM TestLabs, TST, etc. An independent auditor like eCOGRA not only certifies RNG fairness but also mediates disputes between players and casinos, upholding player protection and responsible operator conduct standards.

Licensing and Regulation Compliance

Reputable providers operate under strict regulatory standards. They often hold licences from recognised gambling authorities like the MGA and the UKGC. This ensures they meet high standards for safety and fairness. It also points to their credibility within the industry.

Top Providers of Slot Games

Online slots are the focus of many casino software companies and the flexibility of these games allows developers to stretch their creative limbs. There are lots of great slot providers out there.

They also offer progressive jackpots in some of their table games, like Roulette Royale and Caribbean Draw Poker.
  • NetEnt – NetEnt is not just a leader in slots but also in table games.

Providers of Live Dealer Casino Games

Live dealer games have transformed the online casino experience by bridging the gap between virtual and brick-and-mortar casinos. Unlike regular RNG games, which rely on computer algorithms to determine game outcomes, live dealer games are streamed in real-time and are managed by human dealers. This setup brings the authentic feel of a physical casino into the player’s environment, complete with real-time interaction, live action, and a communal gaming atmosphere.

At the forefront of the live casino revolution is Evolution, widely agreed upon as the leading live casino company. Evolution has set high standards with its diverse range of live dealer games, which include classics like blackjack, roulette, baccarat, and poker.

Mobile gaming has become a necessity for many players in today’s fast-paced world. There’s a huge demand for mobile online casinos, so you need mobile games to go alongside. New developers looking to break into the market are taking a mobile-first approach to their game development (building omni-channel HTML5 games). Established game companies are also updating their game development processes and converting released titles into mobile-compatible formats.

Frankly, there’s hardly a provider that doesn’t cater to the mobile gaming populace right now, but some do mobile games better than others. We’re talking about names like NetEnt, Playtech, Play ‘n GO and Yggdrasil. With their Touch series,  NetEnt has adapted many of their popular games for mobile devices. And their mobile games maintain the same high-quality graphics and gameplay as their desktop versions. For Play ‘n GO, their commitment to mobile gaming is in their name. They are highly focused on creating mobile-optimised games that players can enjoy on the go, and they don’t compromise on quality.

Yggdrasil’s iSense technology ensures that their games run smoothly on mobile devices, with sleek animations and user-friendly gameplay.

Each of these providers has recognized the importance of mobile gaming and is actively committed to meeting the needs of the modern player. Their strengths lie not only in the quality of games available but also in the seamlessness of the mobile gaming experiences they provide.

Tips for Finding the Best Casino Game Providers

Selecting the right game providers can significantly enhance your gaming experience. So here are some key factors to consider:

  • Device Compatibility – Ensure that the provider’s games are supported across various devices, including desktops, tablets, and smartphones. Easy accessibility and smooth gameplay on any device are key to a good gaming experience.
  • Player Reviews and Reputation – Checking player reviews and the provider’s reputation can give you insight into their reliability and the overall player experience they offer.

Online Casino Software FAQ

Who are the top providers of online casino software?

The leading online casino software providers include NetEnt, Microgaming, Playtech, Evolution Gaming, Pragmatic Play, and Betsoft. These game companies are known for their quality, innovation, and varied range of games.

How do I know if online casino software is fair?

Casino software is fair if it runs on an RNG. But that’s not all. RNGs must be tested by regularly audited by independent third parties like eCOGRA to ensure they are actually random (as they should be) and not manipulated.

Can online casino software be rigged?

Technically, it’s possible for gaming software to be manipulated. This is where independent testers like eCOGRA come in. The quality of online casinos that feature the said software also matters. Top casinos that are licensed and regulated must adhere to certain standards of fair play. Rigging is highly unlikely at these sites.

Can I play different software providers’ games at one casino?

Yes, you can. Many casinos online offer games from multiple software providers, giving players a wide variety of games to choose from. You can often find hundreds or thousands of slots and other games at the best sites.

How often do software providers release new games?

There’s no specific timeframe for releasing new games, and each provider typically goes at their own pace. Adding new games keeps things fresh and interesting for players, so the leading software studios often have a regular release schedule of about one to three new games monthly.
