Casino Software

Last Updated: 

The software provider that an online casino chooses to partner with is one of the most crucial aspects of that casino's identity. Beyond determining site functionality, the games available at a given casino is also affected by who they work with.

If you’re looking to play online casino games, it’s important to understand the difference between a top casino operator and a casino software provider. When you sign up and deposit with a casino operator, they are not usually the company who have created the brilliant online slot games that you are likely to enjoy thanks to becoming a customer. That comes down to the casino site’s partnership with a casino software provider.

It used to be the case that a casino operator would work exclusively with one software provider, something that was fairly restrictive and times have thankfully changed. Now it’s pretty common for a casino site to have games provided to them by a wide range of software companies, with Playtech and NetEnt among the biggest ones.

Please note that when you’re looking for a good casino software provider, this isn’t just restricted to online slots sites. It also applies to Live Casino and it’s fairly common to see Evolution Gaming as the mainstay of many casinos’ live dealer offering, with this company providing superb live-streamed action. The same also applies to video poker and table games.

Top Online Gaming Software Developers

Any first-class gambling site relies on forming strong partnerships with leading casino software providers. An operator could have a first-class casino interface, brilliant free casino bets and excellent customer service, although casino players want something beyond the shop window and the casino software companies are able to meet the customer demand thanks to unique lines of casino games.

You might notice that each casino software provider offers something slightly different to the gambling site. It might be a reputation of big money jackpots or alternatively it might just be distinctive graphics which means customers can quickly tell that they’re playing a NetEnt slot.

Fantastic gaming software developers never stand still either. There is always a new release around the corner in the same way that people want to watch the latest blockbuster movie. After all, casino software providers are in direct competition when it comes to customers playing their games through the casino sites with which they work.


How We Rate the Best Online Gambling Software Providers

When it comes to rating the best gambling software providers, we use different pieces of criteria in order to come up with our ultimate ranking order. A good casino software firm will score highly across the board for different categories and one of the biggest reveals comes down to the casino software that operators choose to use on their own site.

Naturally, we will look at a software company’s history to judge them and that is a pretty good barometer when it comes to trust. A software giant that were one of the first to create online casino slots clearly trumps a new kid on the block in terms of trust, although it also helps if we see evidence that the software firm is UK-licensed and regulated. After all, it’s not just the casino sites which need to have a gambling license.

There are also many industry awards knocking around every year and you can easily find information relating to which casino software providers are successful on this front. The awards are generally down to an independent panel of judges who will look at the reputation of that software provider’s game range, while it’s also imperative that they adhere to the strictest standards when it comes to RNG so the games are fair.

While all of the above factors form a solid benchmark for how we rate casino software providers, the proof of the pudding is in the eating. Therefore, our experts take a firm look at each software provider’s range of casino slots and judge the strength of each portfolio. It’s no exaggeration to say that some of the leading firms have thousands of available games that can be hand-picked by an operator.

It always helps if a casino software provider has created slot games that have a Progressive Jackpot and that is generally made available on a network so that the amounts get bigger in a shorter space of time. We also look at the RTP (Return to Player) for each available game, with the higher percentage being more favourable in terms of the return that can be enjoyed along the way.

It’s important that the game play is first-class and that includes the layout of the game, the graphics and the sound effects. A casino provider will get extra marks for having the latest video slots which feature clips from popular movies, while we’re looking for the highest entertainment value possible. All this information can be found on in the software provider reviews and slot reviews.

Other Casino Software Developers Available in the UK

Despite our extensive list of the main casino software developers, there are actually a huge number of other companies that either create new casino titles, provide features which are adopted by casino games makers or simply provide a way of transporting the gaming experience to the operator websites.

You may have heard of the likes of:

All of these software providers deserve recognition for helping to power those award-winning casino operators who sometimes have to just make sure that the games are plugged in and they’re available to play.

We should also note that the likes of Playtech have smaller software subsidiaries that form part of their company but also operate as separate entities, thus ensuring the likes of Quickfire and Ash Gaming are still recognised in their own right. As technology continues to move on at such a fast pace, we will see plenty of newcomers entering the market.

Mobile Casino Game Providers

An increasing number of online casino players are using their mobile device to access mobile casino UK and to play slots and that means that software providers need to find ways to create casino games which are highly optimised through mobile as well as desktop. Sometimes a casino game is made primarily for mobile play and there will be a focus on how a consumer interacts with a smaller screen, while sound is usually compromised considering that this works better through a desktop or even a tablet.

When it comes to casino games providers, some have games which aren’t available through mobile. That might be because they’re not adaptable to a mobile device or it might be that they are specifically designed for a PC or laptop. Sometimes, you might need to download a particular casino mobile app in order to access the full range of games software and this can usually be easily acquired through the Apple store or the Google Play store.


Live Casino Software Providers

We’ve talked extensively about online casino slots and it’s true that they account for a high percentage of casino play when it comes to each casino operator. However, many customers are looking for more options when they visit an online casino and that includes some exciting Live Dealer opportunities. Indeed, it’s very rare to find an operator doesn’t have Live Casino games available, with customers wanting to experience the thrill that comes with this sort of experience.

It’s really no secret that Evolution Gaming lead the way when it comes to Live Casino and this software provider have a global operation in place. This means a customer anywhere in the world can access one of their products and find a language version that caters for them, along with a choice of game from blackjack, roulette, baccarat or many other alternatives.

NetEnt and Playtech also have Live Casino software that is utilised by casino operators and it’s a case of having a professional set-up at land-based casinos and then using advanced technology to live stream the game play through an operator website. That allows a customer to visit a particular game and see a professional croupier spinning the roulette wheel or dealing the blackjack cards.

The key is to provide the right look and feel so that customers completely trust the experience. It also needs to be fun, with small details like the sound and the lightning essential to the overall gameplay. It’s akin to running a successful television network, with the eyes of the customers on the house and there also has to be a reliability of the streaming at all times.

Slot Machine Developers

While Evolution Gaming continue to relentless march on with new live casino products like Crazy Time and Mega Ball, the bottom line is the vast majority of casino software developers are chiefly focused on slot machines development. Casino slots can make big money for an operator due to the repetitive play element which means customers are continuously spinning the reels, while even a high percentage RTP means that players are losing more than they are winning.

Therefore and NetEnt are all aiming to come up with the latest slot release smash that is going to be snapped up every casino site under the sun. There is millions of pounds invested into creating something new, slick and highly playable which is going to catch the casino world by storm. Sometimes it will be the latest slot chapter of an ongoing series, while it might be a brand new theme which has mass appeal.

You will notice that some online slot games are trademarked and that is particularly the video slots due to the fact that movie franchises will sometimes sell the rights to create an online casino slot game to the highest bidder. Therefore, you might find developers are bidding against each other to secure the rights to adapt a movie to a video slot and that includes using movie clips as part of the bonus features.

Naturally, different online slots appeal to different customers and software providers have to therefore cater for a range of different tastes. Some will create new casino slots that have a very high RTP, although some customers want a high volatility slot where they can play for higher stakes and potentially land a bigger win than a high RTP equivalent.

Other Casino Games Software Providers

When online casinos were first launched, there was no such thing as Live Casino and there were only some very basic slot games. Software providers might have been pioneering new releases, although they were also creating plenty of table game software so that customers no longer had to visit a brick-and-mortar establishment to play roulette and blackjack, games which are the mainstay of a land-based casino.

The leading casino software providers continue to develop cutting-edge table games with smart graphics that are highly playable, with the gameplay allowing customers to remain at the table for long periods of time. Many customers still like to keep things retro and play video poker, while scratchcards are another vertical where some casino providers work on products that serve as added value when added to a casino site.

Safe, Fair and Legal Casino Software Developers


It’s not only casino operators that need to have a gambling license. Ultimately, they simply provide the framework for casino slots and Live Casino games, so it’s imperative that a software provider is also UK-licensed and regulated. It doesn’t matter whether they are regarded as “back office”, they are still responsible for providing the games software and operators have to make sure they are acquiring games which are legitimate and fair.

It also means that casino software companies have all their games assessed. When a new online slot is created, it needs to be independently tested to make sure that the RNG (Random Number Generator) is happening correctly which matches up with the RTP percentage. There also needs to be a thorough examination of the workings of a Progressive Jackpot to ensure that the pot is randomly triggered.

It’s usually possible to see the software developer that is behind the casino game, although the fact that your actual casino site adheres to UK regulations means that their games have consequently been tested. That means you can experience a secure game playing experience where there’s always a chance to win real money.
