Top 5 Casino Software Providers

We list all of the UK casino gaming software providers further on, but picking the best one isn’t an easy task.

Our individual software pages will give you a more in-depth insight into each one, which will make your choice a lot simpler. But let’s list the top five providers in the UK and break down each one for you.

  1. NetEnt
  2. Microgaming
  3. Playtech
  4. Evolution Gaming
  5. Play’n GO


NetEnt is arguably the best casino software company around. Their games are widely available at UK casino sites and they continue to release innovative new slots to stay ahead of the competition.

Street Fighter II: The Word Warrior Slot is a prime example of one of their more recent releases that’s loved by many. But the one you may have come across before is Starburst. It’s a slot that is usually attached to many UK free spins promotions.

If you’re a fan of progressive jackpots, you may also be familiar with their Mega Fortune slot. It’s a household name in the NetEnt library of games.

One lucky player won €18 million from a 25 cent stake on the iconic slot back in 2015! It’s one of the largest amounts ever paid out on a progressive slot.

NetEnt is much more than just a provider of slots as it also boasts an impressive video poker and table games product. Operating under NetEnt Live to give players an authentic live casino experience, they’ve been on an upward trajectory in recent years.

The Sun Vegas is an example of a top UK casino that has plenty of NetEnt games in its lobby.

Microgaming is another trustworthy company providing casino gaming software that has many strings to its bow. Launched two years earlier than NetEnt back in 1994, they offer hundreds of games for casino players to enjoy.

One of the most recognisable progressives is a Microgaming creation – Mega Moolah. With a Return To Player (RTP) percentage of less than 90%, it’s not the best slot to play in terms of payout rate.

They can, however, be quite lucrative compared to other slots. Much like Mega Fortune, Mega Moolah payouts can run into the millions.

Other popular slots include Thunderstruck and Immortal Romance, but this software provider also has a strong presence with well-designed table games at online casinos.

A top site offering Microgaming slots is Unibet. Take a look at their bonus offer below and feel free to register for a new account and try out some games.

They’re known for their well-liked Age of the Gods slots. There are 14 variations, including:

The series began as a simple Viking themed slot and it’s now progressed and evolved into other unique slots and even roulette.

William Hill Casino is a trusted UK site that uses proven and tested Playtech software.

Evolution Gaming

Evolution Gaming is the world’s most trusted provider of live online casino software. The majority of the top sites use them and they’ve picked up countless industry awards for high quality since they were founded back in 2006.

If you play slots and are wondering why you don’t see any of their games available, that’s because there aren’t any. They’ve kept a clear focus on developing live casino products which has lead them to become a leader in this field.

The casino gaming software offered by Evolution Gaming works flawlessly on smartphones, tablets, and desktops.

They offer one of the most diverse selections of live dealer games at casino sites, with numerous variations of popular table games to choose from. Some of their more favoured titles include:

  • Monopoly Live
  • Lightning Roulette

There’s an extremely popular slot called the Book of Dead that’s attached to many UK bonuses. This is a Play’n GO creation. Simple games and impressive graphics are synonymous with titles from this well-respected developer.

It’s why they appeal to some many players as they’re designed to make for a fun experience. There’s also the chance to win big jackpots.

It’s not just slots where this online casino software provider excels. Play’n GO also boast their own versions of Caribbean Stud Poker and blackjack. They have a strong presence at sites with numerous variations of table games and cater to all types of players.

How We Rate Casino Gaming Software

We’ve told you what the best casino software companies in the UK are, but we haven’t told you why. What makes them so good? We take many important factors into consideration when rating each supplier.

Here’s the strict criteria we match them against before they get the thumbs up from us as one of the best:

The two most important factors are the UK licence and game fairness. All casinos listed on our website are perfectly fine in this regard. The audit around trustworthiness is done by an independent charity such as eCOGRA.

The first noticeable thing you’ll see from a top software provider as a player is just how good their games are. Some of the graphics are incredible and they make for a great betting experience.

They often release new titles at regular intervals. You’re never left waiting for too long before there’s an exciting new slot or table game to try. Play’n GO are a good example of this as they release a few new slots every week.

How Does Casino Gaming Software Work?

Casino Deal Software Developers

A common concern amongst players like you and I when it comes to casino gaming software is how fair is it?

Thankfully, every top UK casino site that holds a valid licence is fair as they have to adhere to strict rules and regulations set out by the UK Gambling Commission.

There are two important terms associated with how the software works that you need to be aware of. Return to Player (RTP) and Random Number Generator (RNG).

Each slot will have a predetermined RTP percentage that indicates how much is paid out over time. Just remember the higher the RTP percentage, the better it is for you in the long run.

At the core of casino gaming software around payout rates is RNG. This determines the outcome of each slot spin, the shuffle of a deck or roll of the dice. Everything is completely random, which ensures complete fairness as a result.

Another crucial element that online casino software companies work on is enhancing the user experience. It’s even more important these days with the rise in mobile gaming.

The software created must be responsive and adaptive to the needs of each user. You’ll have players on iPhones and players on Android devices with different screen sizes and hardware specifications. They need to cater to everyone.

Types of Online Gaming Software

The rapid advancement of technology in recent years has allowed casino gaming software development to improve exponentially. You can now enjoy games at your favourite casino on various different platforms. Let’s outline the options available to you.

Download vs Instant Play

There used to be a time when all you could do was download a UK casino’s betting platform in order to play games. Nowadays, you can play games instantly without the need for any extra casino software. It’s much more convenient.

Table games and slots can be enjoyed instantly. However, there are a few sites out there where you might need to download separate software to play poker.

While the embedded software may have meant richer graphics in the past, technology progression has seen that advantage reduced.

Furthermore, there can be device restrictions on individual software platforms, whereas playing instantly on a mobile device is not a problem.

Here are some advantages and disadvantages to using instant play casinos compared to downloaded software:

Pros of an Instant Play Casino
  • Can offer games from multiple providers
  • Can play at the newest casino sites
  • Games available on any device
  • All UK casinos are available for instant play
  • UKGC licenced sites are safe and secure
  • Enjoy promotions and bonus offers
Cons of an Instant Play Casino
  • Could have a smaller game selection
  • Game quality relies on a good connection
  • Graphics may not be as good

Desktop vs Mobile Casino

Players have switched their attention to gaming on a phone or a tablet over the last few years. Over half of all UK casino players prefer to bet on a mobile device as it’s easy and extremely convenient.

Gone are the days where you had to switch between mobile and desktop to find your favourite game. What’s available on desktop is now available on mobile.

What’s also beneficial is that mobile games load just as fast as desktop games if your connection is good.

If you’re planning to play some slots or table games on your mobile, one piece of advice from us would be to ensure your device is charged.

Your battery does drain quickly playing games at an online casino, so don’t get caught short in the middle of a poker session for example.

Some prefer playing on a larger screen, which is why there are still many out there that prefer betting on a desktop. Although with handheld screens constantly increasing in size, that’s not too much of a negative for mobile players anymore.

It’s difficult to pick a clear winner when comparing the two. It boils down to personal choice. Some will prefer the smaller screen and the convenience of a phone or tablet, whereas others will prefer improved graphics on a larger device.

In-House Casino Software

While many UK casinos like to use third-party casino gaming software such as NetEnt or Microgaming, some have developed their own in-house platforms.

888Casino is a prime example of a top UK site using proprietary software. This means that they can develop games exclusively for 888 customers. It gives them a unique selling point and allows them to differentiate from their competitors.

You still get to experience products from third-party suppliers this way, but you’ve got the added bonus of games made available exclusively to you.

Furthermore, it allows any casino with their own software to easily promote new games and offer bonuses on them. They don’t have to worry about any stipulations that may come from third parties.

Can I Trust the Software?

Yes, to put it simply. As we touched on earlier, every casino must hold a valid UK licence and the software they provide must be fair.

eCOGRA ensures UK casinos are fully compliant when it comes to fair gaming, player protection and responsible conduct. They test the RNG software rigorously, so rest assured that any provider listed here is safe, secure, and trustworthy.

The best casino software companies are fully transparent when it comes to information around game RTP percentages and any certifications. So too are the sites that list the providers.

Most have these details listed on their website for anyone who wants to know more on this.

You now know the top gaming software companies in the UK and why they’re rated so highly. There are plenty to choose from and all come with their own unique advantages and disadvantages.

It’s worth testing out games from a number of providers to see which supplier you prefer. You may even prefer a mixture of a few like many others do. But what you will always be met with is high security, integrity, and fairness.

Whether it’s frequent promotions, quality graphics or high RTP slots you’re after, any of our top casino gaming software providers are worthwhile choices.
