NetEnt is one of the largest, most famous game developers in the casino industry. They’ve been setting trends for slots development for more than 20 years and have 200+ excellent game titles in their portfolio. Some of the best jackpot slots came out of their studios. The appeal of NetEnt slots lies in the gameplay-enhancing features and their high RTP. You can find tons of great online casinos offering rewarding bonuses dedicated to NetEnt slots. And now, as part of Evolution Gaming, you’ll be able to enjoy superb live gaming at the best NetEnt casinos.

Play’n Go

Play’n GO is a software developer dedicated to the entertainment factor of its offering. The Swedish casino game provider has only been on the market since 2004 but has since become one of the best-known brands in the iGaming industry. And thanks to its constant desire to create new and improved titles with captivating themes and sharp visuals, Play’n GO will likely remain a dominating force in the sector for years to come. With slot games at the forefront of its portfolio, players get to enjoy a varied selection of superb-quality titles and thrilling, action-packed game sessions.


Microgaming is one of the most recognizable brands in the iGaming world. A true pioneer of the industry, this developer has been a trendsetter since day one. Having launched the first online casino platform, and later the first-ever mobile casino platform, Microgaming has been shaping the gaming world as we know it for decades now. The company is also involved in continuous growth and expansion when it comes to its portfolio too. Today Microgaming boasts over 850 casino games, from slots to table games and beyond. And each new release shows how diligently the developer is working on evolving further.


Still considered a newcomer in the gaming world, Quickspin has surpassed many of its competitors thanks to a very passionate and dedicated approach to its products. The company was founded by slot game enthusiasts who wanted to create slots they would enjoy playing themselves. And as a result, Quickspin is one of today’s leading slot developers, featuring an abundant and diverse portfolio of high-quality titles. Quickspin’s games are easily recognized by their exceptional visuals and presence of unique special features. And they come in a variety of styles and genres, from classic slots to sophisticated and ultra-modern offerings.


Without a shadow of a doubt, Thunderkick is one of the most innovative and extraordinary casino developers. Their slots are easily recognisable among online gamblers. The provider strives for excellence and makes sure you’ll feast all of your senses on perfect execution. While Thunderkick developers only slots, you can be sure they create excellent, in fact, some of the best slots available today. They have some of the most popular titles in their portfolio, packed to the brim with extra features and game-enhancing mechanics. Playing Thunderkick slots is a treat, and you can enjoy it on mobile devices, as well, just as long as you join a mobile-friendly casino.

What Are Game Providers?

When you go to any online casino, in nearly 99% of the cases the games you see there are not the product of that casino. In other words, online casinos do not actually make the games that they offer their players. That is done by software developing companies that specialize in the creation of casino games. And in turn, these software developers have partnerships with certain casinos to provide them with their offerings. In fact, some casinos even have exclusive partnerships, where they only offer the software of a single game developer.

And as you will notice over time the more games you play, each software provider has their own unique strengths and weaknesses. These traits are what often lead players to prefer a certain game manufacturer over the rest. And hence, they will often seek out best casino sites based on the software that they offer. We will cover all of the different aspects that make casino game developers unique in this guide. And we will also give you examples of some of the world’s leading developers, as well as their unrivaled selling points that make them so sought after today.

Different Types of Casino Software Providers

There are two main distinctions as far as software developers go in the gaming industry. On the one hand we have the game providers that only take care of creating different titles. Whether it is table games, slot games or live dealer casino titles – they are only responsible for delivering the software to the respective casino or casinos that they have partnerships with.

And then there are the more complex and larger brands that offer entire iGaming platforms of their own. Their services don’t just cover developing the games. Although plenty of their resources certainly also go into the creation of high-quality, entertaining offerings. In addition to that, such providers can also handle marketing, monetizing and offer solutions for other parts of the business.

Essentially, they have created their very own platforms that can be integrated into the online casino’s structure. Examples of such software developers include major brands like Microgaming, Playtech and Netent. Which is the preferred option? That depends mainly on the casino. Some may prefer to work together with a large industry presence in exchange for a larger portion of their profits. And others may wish to handle their marketing and other matters on their own.

What Makes a Casino Game Provider Good?

When you think of game developers in terms of their products, there is a lot that goes into them. And each one of these aspects really needs to be up to standard – otherwise it shows. And if there’s something wrong with the game, it won’t be enjoyable.

But aside from that, some aspects are usually the company’s forte and main emphasis in a game. And depending on where you stand as a player, you may like certain games exactly because of that one or selection of aspect. For instance, you may be a big fan of 3D graphics and are exceptionally into the visuals. Or perhaps the structure of the games may be more important to you, etc. In any event, these are all aspects present in all games. And here’s how you know whether they’re good or not.

Gameplay is a broad term that encompasses the game’s rules, features and just the general experience players get. And of course, gameplay will vary dramatically based on the exact type of game. For instance, if it’s a modern slot game, the developer may include more elaborate bonus rounds and special features. Classic slots, on the other hand, call for more minimalism in that respect. There can’t be any bonus features and other extras. Instead, the focus in these types of games needs to be elsewhere. Hence, developers need to be able to tailor their games to the exact audience they’re catering to.


This is perhaps our favorite part of any game. Although not everyone cares so much about the visuals of a game, but a fair share do enjoy us some good eye candy. As technology progresses, so do the standards for graphics quality. Today we want games to look all glossy and shiny. And if the graphics comes in the 3D – all the better! Of course, the 3D visuals need to be executed perfectly for them to actually be appreciated by players.

And that’s where the difficulty lies, as well as where the true professional’s hand is noticed. And graphics aren’t necessarily all drawn on. With live dealer casino titles, for example, developers need to have superb quality cameras and streaming technology to offer a crystal-clear picture in high definition.


This is another aspect that may often seem insignificant at first but plays a crucial role in your overall gaming experience. If a game you’re playing has an annoying soundtrack, you will mute it at best, or will simply not play it. In addition to the music playing, the reels or spinning wheel (depending on the game you’re playing) make sounds, too. Hence, software developers also put in the due effort to perfectly match the audio to their games. For modern slots, this will usually be a fun and engaging soundtrack. And for table games you’d expect a more relaxing, laid-back sound.


In the rapidly developing and fiercely competitive iGaming industry, innovation is king. Whether you’re a big brand that’s been on the market for decades or a newcomer, you need to keep up with the trends. Or better yet – you need to set the trends. Software manufacturers are constantly in a race to come up with new themes, groundbreaking features and unique technologies that no one else has. For instance, one of the latest says in today’s iGaming world is the use of VR technology. It isn’t widely available just yet. But some software developers like Mircogaming and Netent have already made their first steps in that direction.


Of course, we mainly play casino games for the fun of it. But part of the fun in playing these games is determined by our wins. Hence, payouts are an important aspect of any game. All online casino games have something known as an RTP – the return to player ratio. It is the estimates percentage of the funds you put into a game that you can expect to get back over time. Some games have a higher RTP than others and of course, its’ always preferable to play games that can offer you higher payouts. Volatility is another thing to consider here, and some developers are notorious for creating either highly volatile titles or quite the opposite.


As much as we may value a certain software provider for a trait that is uniquely theirs, variety is still important. So for a game developers to have more value, their products need to be different. There needs to be enough of several options to choose from, or things will just get boring. And that doesn’t mean that all software developers need to offer every type of casino game out there. What it means is that they need to have a good amount of variety within their chosen categories. For example, Evolution Gaming specializes in live dealer games. And they have a wide range of different offerings within that category.

Mobile compatibility

Research has shown that roughly half of all online gaming is done on mobile devices. And that trend seems to be increasing in favor of smartphones and other gadgets. With that in mind, mobile compatibility of casino games these days is a must-have. This means also that games need to not only be accessibly from mobile devices – they need to be just as enjoyable. So it’s up to the developers to make sure that their games are optimized to work seamlessly on all operating systems and devices. And if the online casino has their own app, then the games need to be integrated in that app, as well.

Safety and Licences

Although we’ve listed this aspect last, it’s by no means any less critical than any of the others mentioned here. Security in terms of casino games first and foremost relates to fair play.All game providers are required to be licensed and regulated by at least one of the major gaming authorities. And depending on the license they hold, they can then provide their services in certain jurisdictions. In addition, there are independent software testing organizations, such as eCOGRA that check each company’s RNG (random number generator) to make sure it works properly.

Some of the Best Companies on the Market

As promised, we’d like to mention some of the most well-established and renowned software developers and what they are best known for.

  • IGT. IGT is a major presence in the industry and has been around long before the dawn of online gambling. In fact, the company’s history dates back to the 1970s. And since then it’s become a staple for high-quality gaming products, including large-scale collaborations with big film studios to create film-based games, such as for instance the interactive slot “Avatar”.
  • Evolution Gaming. Evolution is undoubtedly the number one live dealer casino game provider in the world. The developer has perfected the art of delivering immersive games with HD video streaming from luxurious studios and with professional croupiers.
  • Microgaming. Microgaming is another manufacturer that has been on the market for decades. It has arguably the richest portfolio with all sorts of games, and hits that are still played years and years after their initial release. Microgaming is also especially well-known for its progressive slot games, such as “Mega Moolah” that has made more than just one millionaire over the years.
  • Netent. Netent is one of the most prominent brands in the realm of online slot games. The company has really developed its unique style of games, and constantly comes up with unique features and highly entertaining themes. And the packaging? Outstanding.
