Slot Providers

Top Slot Providers

If you’ve ever played an online slot before, you’ve probably played a game created by one of these top slot providers. They have become big names in the online gaming industry for good reason by creating games that combine classy design with innovative gameplay. Here are our best 8:

Relax Gaming

Relax Gaming is a prominent game provider in the online casino industry, known for its diverse and innovative portfolio of slot games, poker, bingo, and aggregation services. Established in 2010, Relax Gaming’s reputation is built on high-quality graphics, unique themes, and engaging gameplay.

Their Money Train 2 slot has achieved cult status, and some other notable titles include Temple Tumble, Iron Bank, and Snake Arena. They boast over 100 games in their slot portfolio, and their Dream Drop jackpot series has gained a lot of popularity since its inception in 2022.

NetEnt

One of the industry’s biggest providers, NetEnt, are the people behind smash-hit slots like Starburst, Dead or Alive 2, and Gonzo’s Quest. Founded in 1996, their graphically rich slots are very easy on the eye and often come with cracking features to match.

NetEnt technology was involved in over 58 billion online gaming transactions in 2019 which gives you an idea of just how popular their games are. They also offer over 200 slot games to choose from.

Games Global

Games Global are probably best known for its collection of progressive jackpot slots, including the Mega Moolah, WowPot and Major Millions networks. Their WowPot! Wheels of Wishes slot holds the record for the largest progressive jackpot won at a staggering €38,461,200.95.

Games Global has also created a host of branded slots, including titles based on Terminator 2, Game of Thrones, I’m a Celebrity Get Me Out of Here, and many more. They also have over 1,300 games in total.

Big Time Gaming

The biggest innovation in the online gaming world over the past couple of years has been the rise of the Megaways game mechanic. Sydney’s Big Time Gaming is the slot provider behind this massively influential game engine. The game that started the Megaways boom was Bonanza Megaways. BTG is also behind the likes of Extra Chili Megaways and Who Wants to be a Millionaire Megaways.

The Megaways technology has been licensed to other developers, so plenty of other slot developers have put their stamp on BTG’s original technology. BTG isn’t resting on its laurels, though. They’ve also launched Megaclusters and Megaquads game mechanics.

Nolimit City

Launched in 2014, Nolimit City has made a name for itself by creating superbly designed slots that come with rather unusual gameplay. They’re often massively volatile, too. Prime examples of that rather enticing combination include the anarchic Punk Rocker and the hip hop-themed East Coast vs West Coast.

They are also responsible for the San Quentin slot, which pays up to 150,000 x stake wins. If you like slots that offer something a little bit different as far as gameplay is concerned, then Nolimit City slots are well worth investigating, thanks to their xWays, xNudge, xBomb and xPays mechanics.

Play ‘n GO

If you like slots packed full of design flair, look no further than Play ’n GO. Regardless of the theme or style of slot (and they offer plenty of both), you can guarantee that a slot from the Play’n Go catalogue will be easy on the senses. Their games aren’t all style over substance, either. They often pack a very volatile payout punch, too.

Play ’n GO is the slot provider behind the hugely popular Rich Wilde character who stars in slots including Book of Dead, Amulet of the Dead and Pearls of India. With a new Play ‘n GO game every week, they have a great selection of Cluster Pays slots.

Pragmatic Play

Since 2015, Pragmatic Play, a company based in Gibraltar, has been rocking the iGaming world with its diverse slot titles. They are a rather prolific provider that releases new titles on the regular and has a bunch of award-winning games.

Some of their most popular slots and fan favourites include the John Hunter series (e.g. John Hunter and the Book of Tut), Sweet Bonanza, Gates of Olympus, and more.

Playtech

Playtech has been creating slots for over 20 years now, and you’ll find their games at hundreds of online casinos and slot sites.  They’re probably best known for the graphically rich and feature-filled Age of the Gods series. Inspired by ancient Greek myth and legend, they also offer players the chance to land potentially enormous progressive jackpot prizes.

Playtech is also the brains behind the fantasy-themed Kingdoms Rise series and a massive collection of branded slots, including the DC Comic Book Super Heroes and Sporting Legends series. They’re also the creators of the Fire Blaze Jackpots collection.

What Makes a Good Slot Provider?

With so many online slot games to play and lots of providers creating them, we look at the factors that make the slot studios good:

Portfolio of Slots

Does the slot provider have an extensive and high-quality back catalogue of games? The likes of Games Global and Play ’n GO release slots on a weekly basis. Browse through their portfolio and you’ll have a pretty good idea of the type of thing you can expect.

Other smaller slot providers aren’t usually as prolific. With a focus on quality rather than quantity, there’s usually a bit of a gap between releases from the likes of Push Gaming and 4ThePlayer. Content from these niche slot developers can be worth waiting for, though.

Availability Across Multiple Devices

With more and more of us using a smartphone as a primary device, does the slot provider create content that’s fully optimised for mobile and tablet play? Most slot games are developed using HTML5 technology, so they run smoothly on all devices.

Veteran land-based developers like IGT and Novomatic often retrofit their classic titles so they’re available for play online and via mobile. As mentioned above, some slot providers are mobile-first, which helps with players who play on the go.

Interface

There’s really no excuse for a slot not to be easy to understand and play. The paytable should be clear and simple to follow, and the design should be clear and crisp. Some slot providers like Play ‘n GO have an in-house style when it comes to the user interface, and that familiarity makes their games nice and straightforward. Others, like IGT, often require a little bit more effort.

Licenses

Online casinos need to be licensed in order to operate, and there are regulations in place for slot providers, too. The UK Gambling Commission is the regulator in Britain. Slots available at the top UK casinos are licensed by the UKGC.

You will also notice that slot developers have licenses in Alderney, Malta, Gibraltar and US states where online gaming is legal. If you see slots you’re unsure about, check out the provider’s license credentials to see if they are legit or not. Saying that all slots found at UK-licensed slot sites come from a licensed and reputable developer.

RTP %

Return to Player (RTP) rates vary widely from slot to slot. The average RTP rate comes in at around 96%. Some developers like Play ‘n GO have different RTP rates for different territories. For other slot providers like Big Time Gaming, the RTP rates are uniform regardless of where you’re playing.

The better slot developers will generally offer higher RTP rates, especially in the UK. It can also vary from casino to casino. You want to be playing the highest-paying version of any slot game to get the most back (on average).

Innovation

Players expect more from slots than just vanilla gameplay and payline wins. More and more slot providers are creating innovative mechanics and bonus features.

The iconic Avalanche feature first appeared in NetEnt’s Gonzo’s Quest slot and proved wildly popular. Likewise, the Megaways mechanic from Big Time Gaming is now on offer in hundreds of slots with a massive variety of themes.

It’s not just gameplay that’s ripe for innovation. Design is, too. Many graphically rich slots are a world away from the simple fruit machines of old.

There are slot developers like Nolimit City that have managed to innovate on many fronts. The unusual design and theme in the likes of Punk Rocker come with the provider’s innovative nudge technology. You’ll find similarly high-class design in San Quentin, played using the xWays mechanic. Design flair and innovative gameplay are a pretty enticing combination.

Safety + Security

The first thing a slot should be is safe and secure. Reputable slot developers have their games tested and audited by external operators to ensure they are fair and their RTP rates are accurate.

The best-known of these testing bodies is the UK’s eCOGRA (eCommerce and Online Gaming Regulation and Assurance). Other high-profile testers include Australia’s iTechLabs, BMM TestLabs (founded in 1981), TST and Gaming Laboratories International.

Casino Availability

Are slots from a particular developer available at various casino sites? If they are, that’s usually a good sign and means they have a good reputation. The top online casinos will have content from a wide range of developers. If they’re rubbing shoulders with the top name providers at a slot site with instant name recognition, that’s a good sign of reliability and trustworthiness.
