1. Games Global
Background
Originally known as Microgaming, Games Global is a software company based on the Isle of Man, founded in 1994, and is one of the oldest online slot providers. With over 50 partner studios, 3,000+ exclusive games, and most likely the most well-known progressive jackpot network worldwide, Games Global is an iGaming behemoth. Although their slots are their most well-known product, the brand has also released table games, lottery-style games, bingo; the list goes on.
Reputation
Having been in the business for more than two decades, Games Global is familiar with the nuances of the industry and the expectations and desires of its patrons.
Games Global is fully licensed and regulated by the UK Gambling Commission (licence number 5884) and the Malta Gaming Authority. They also carry certificates from eCOGRA and Gaming Laboratories International (GLI).
Crowned Slot Provider of the Year at International Gaming Awards (ICE) 2024, Games Global’s subsidiary studio, Snowborn Games, won Games Studio of the Year, and another subsidiary, Just For The Win, won Game of the Year for their Golden Fields slot.
Games
Games Global and its affiliated developers have amassed a portfolio of over 3,000 slot machines. Over this time, they have pioneered many industry innovations, including the first multi-network progressive jackpot slot, Mega Moolah, still considered a flagship game for the developer. They were also responsible for the first ever licensed slot machine, releasing Lara Croft: Tomb Raider in 2004. More recently, in 2015, they created the first slot on a wearable device.
There are more slots and achievements of Games Global to highlight than can fit in a single article. But popular slots of note include Immortal Romance, Thunderstruck 2, Lara Croft: Temples and Tombs, and Mermaid Millions.
2. Play’n GO
Background
Play’n GO, which started in Sweden in 2005 with a small staff of developers, is today among the biggest producers of online casino slots worldwide.
Play’n GO is most well-known for being a trailblazer in the mobile gaming scene, and its releases follow a mobile-first strategy. Their portfolio of over 300 games can be played with regulated casino sites in over 25 jurisdictions.
In 2023, Play’n GO Music, a division dedicated to providing original soundtracks for forthcoming game releases, was launched. Their release, Hugo Legacy, which features a soundtrack specially created and recorded by the brilliant Czech Symphony Orchestra, is a shining illustration of this division in action.
Reputation
Play’n GO, fully licensed by the Malta Gaming Authority, among others, and the UK Gambling Commission (licence number: 55949), is a well-regarded developer known for its design flair and creative gaming. Respected third parties such as Gaming Laboratories, bmm Testlabs, and I.B.A.S have audited and accredited their games.
At the International Gaming Awards in 2017 and 2019, Play’n GO was crowned Slot Provider of the Year and won Game of the Year in 2018 for Sweet Alchemy.
At 5 Star Media's Starlet Awards in 2023, Play’n GO became Mobile Supplier of the Year, Slot Provider of the Year, and won the coveted Game of the Year Award for their release Rise of Olympus 100.
Players best know Play’n GO for their adventure-themed slot games, typically with high volatility, above-average RTP, and, of course, full mobile optimisation.
Games
Play’n GO now boasts a library of over 200 games, but undoubtedly their most popular game to date is Book of Dead. This slot inspired other developers to release a slew of archaeologically themed titles, as well as the ‘Book of’ genre. This slot is also the first appearance of Play’n GO’s most well-known character, the dashing adventurer known as Rich Wilde.
Alongside this, other popular slot releases include the Reactoonz series, Sweet Alchemy series, and their ‘of Dead’ titles including the recent release Oasis of Dead.
3. Yggdrasil
Background
Fredrik Elmqvist launched Yggdrasil in 2013. Headquartered in Malta, the brand now operates in 28 jurisdictions around the globe.
Several creative ideas and carefully designed mechanisms have evolved and been used in their games throughout the years, leading to a fast expansion rate for the business in multiple online casino endeavours, most prominently in the slots world. This is fitting with the story behind the brand's name, as Yggdrasil is a tree from Norse Mythology whose branches connect worlds.
With a portfolio currently comprising 300 games, Yggdrasil’s tree has branched out and adopted and collaborated with numerous indie development teams, fuelling their explosive growth rate.
Reputation
Yggdrasil Gaming is licensed and regulated by the Malta Gaming Authority (MGA/B2B/230/2012) and also holds licences awarded by the UKGC, GRA, BGC, BAC, Swedish Gambling Association (SPER), Isle of Man Gambling Supervision Commission, a Hellenic Gambling Commission manufacturer licence, as well as two licences to operate in Romania.
Yggdrasil won Innovator of the Year at the Gambling Awards in 2018, 2020, 2021, and 2023, and Slot Provider of the Year in 2021. It also won Slot Provider of the Year in 2016 at the EGR B2B Awards.
Yggdrasil is best known by players for its broad and creative range of subject matter for its games, often taking well-established themes such as ‘luck o’ the Irish’ and turning them on their head, as in their creation Rainbow Ryan. In terms of innovation, Yggdrasil pioneered the DoubleMax, MultiMax, and GigaMax slot gameplay systems.
Games
As mentioned, Yggdrasil likes to give its games a unique spin. One of their most popular slots is Vikings Go Berzerk (and subsequent additions in the series), which sees a quirky cast of cartoon Vikings with a rising ‘berzerk metre’ leading to a plethora of bonus features.
Rainbow Ryan and its sequel see a rockstar Leprechaun bring all his lucky charm to centre stage, and Hades Gigablox is a mythology slot that takes us away from the clouds and down to the underworld.
4. Evolution Gaming
Background
If you know a little about the online casino world, then you might be surprised to see Evolution on this list, as they’re most known for being a powerhouse in the live casino industry. However, having acquired popular indie developers Nolimit City and Red Tiger Gaming, and established brands NetEnt and Big Time Gaming (BTG), the brand now has a strong presence within the online slot industry.
Originally established in Stockholm in 2006 by a small group of seasoned business leaders, Evolution employs 13,000 people worldwide as of 2024 throughout five continents, operating throughout Europe, North America, and Canada.
Reputation
Evolution Gaming’s reputation can be defined by two words: ‘explosive’ and ‘powerhouse’, particularly regarding the last 5 years of operation. Their achievements within the live casino industry are laudable, if not legendary, and through their acquisition of numerous top-tier development houses, it is clear that something big is brewing in the online slots world.
Through acquiring BTG, Evolution now has the hugely popular Megaways system under its brand, and through Red Tiger Gaming, they have a progressive jackpot network (Daily Drops). Via NetEnt, they gain 28 years of industry experience as well as fan-favourite franchises like Starburst and Gonzo’s Quest, while Nolimit City brings indie flair and their groundbreaking XMechanics.
With so many brands under their umbrella, Evolution Gaming holds licences in pretty much all jurisdictions where gambling is legal, including from notable regulators like the UKGC (licence: 41655), MGA (licence: MGA/CRP/187/2010/01), GCC, AGCC, and GSC.
From 2019-2021, Evolution won Best Online Casino Supplier at the Global Gaming Awards. In 2023, they won Best New Innovative Product for their DigiWheel technology. Most impressively, Evolution has been awarded Live Casino Supplier of the Year for the 12th year running at the EGR B2B Awards; and as many predict the future of online slots is the live casino industry, this achievement shouldn’t be overlooked.
Games
While Evolution Gaming as a parent company isn’t known for any notable online slot releases, its acquisitions most definitely are. They offer BTG’s magnum opus Bonanza, the first Megaways slot, NetEnt's cult classics Gonzo’s Quest and Starburst, Red Tiger’s popular Diamond Blitz and Piggy Riches series, and Nolimit City’s limitless creativity in titles like Deadwood and Tombstone.
5. Pragmatic Play
Background
Established in 2015, Pragmatic Play has offices across the UK, Malta, India, the Philippines, and Ukraine, from their Gibraltar base. Emphasising mobile and desktop digital slots, they are a prominent slot supplier in the iGaming market. Having games in 33 languages, they provide over 300 online slots and over 200 mobile/tablet-compatible slot games.
Reputation
They received their UK Gambling Commission licence in late 2016 (licence number: 56015) and hold over 40 licences allowing them to operate around the globe. The games they produce have been independently audited by Gaming Labs Certified.
The company has received many accolades from EGR, GA, WhichBingo, AskGamblers, SBC, and the Malta Gaming Awards over the years. At the 2023 EGR B2B Awards, Pragmatic Play won Best Casino Software Provider, and at the Global Gaming Awards 2024, they won Best Casino Supplier and Best Product Launch for their Treasure Island game.
Despite having been in the industry for under a decade, Pragmatic Play is best known for their innovative developments in the slots and live casino markets.
Games
While Pragmatic Play’s focus has been on the growing live casino market, they certainly haven’t neglected their slot fans. Their two smash-hit slot franchises highlight the immense range and creativity at Pragmatic. The John Hunter series brings players an Indiana Jones-style adventure, while their Big Bass series, including the popular Big Bass Splash, is all about heading down to the old fishin’ hole.
6. Relax Gaming
Background
Patrik Österåker and Jani Tekoniemi started Relax Gaming in 2010, hoping to become the top technical provider of premium gaming solutions. In the first years of operation, the company focused on other online casino games such as poker and bingo. It wasn’t until 2018 that Relax Gaming released their first online slot, ‘Erik the Red’, and the brand has gone from strength to strength ever since, now with a library of over 100 slot games including series and licensed titles.
Reputation
Their Silver Bullet initiative, designed to draw in and support slot providers, was launched in October 2018. Among others, they teamed with Push Gaming, Big Time Gaming, Kalamba Games, FUGA, and Felt.
Relax Gaming is responsible for the popular progressive jackpot network called Dream Drops. They have also applied mechanics from other companies such as Infinity Reels, Megaways, Megaclusters, and Megapays.
Relax Gaming slots are under control by the UK Gambling Commission (UKGC) with licence number 37462, and their games are certified by industry body eCOGRA.
They won Silver for Casino Software Supplier at the 2023 EGR B2B Awards, and at the 2024 Global Gaming Awards, they won Best Online Slot for their latest release of their flagship series: Money Train 4.
Games
High-quality mechanics (including Megaways and Megaclusters), distinctive reel and payline combinations, a large spectrum of themes, and notable variation in volatility are among Relax Gaming slots' hallmarks. Its approach is based on quality rather than volume, and its most popular slots typically become award winners such as games from their Money Train slot series and Dream Drop progressive jackpot games.

What Makes an Online Slot Provider Next Level?
So, that’s our lucky seven list of top-tier online slot providers; but with countless other exceptional development teams out there, what made us pick those on our shortlist? The following criteria are the core ingredients that separate a great slot provider from the next-level ones.
Reputation and Trustworthiness
If the developer in question is doing things right, you can bet that the many industry award providers will take notice. With categories covering rising stars and debut releases, even the smallest developers will get a share of the limelight if their products are great.
As these awards are often decided (at least in part) with player feedback in consideration, a positive reputation and sense of trustworthiness (usually backed up by top-notch regulatory bodies) are integral to success.
Game Portfolio
While you might think next-level developers need to churn out countless titles with every theme under the sun, this isn’t quite the case. Any basic developer can churn out the same slot with a different cosmetic skin. What makes an exceptional developer can be defined in three ways:
-
- They’ve found their defining niche and have the player base to match, so they focus on high-quality innovations and releases within this niche.
- Their development house covers numerous smaller teams who can therefore provide a large variety of slots covering extensive themes.
- They’ve pinpointed gaps in the market or upcoming trends and curate and release slots that meet these needs or capture those trends.
Software Quality and Performance
Nowadays, it’s a must that games are optimised for play on all devices, including mobile ones; which is why most newer developers define themselves as ‘mobile-first’ creators. On a similar note, the slot should be able to perform in a way that is accessible to as many players as reasonably possible, such as having convenient ways to turn music and sound effects on or off, and providing easy-to-find and clear-to-understand game rules and information.
Licensing and Regulation
A developer's reputation can be destroyed if their games are found on a scam site, so teams need to be discerning regarding who can host their games. This is why next-level developers will only feature games on sites that are fully licensed and regulated. Similarly, developers need to hold current operational licences and should have their games third-party tested to ensure fairness.
Customer Support and Ethical Practice
While it isn’t the developer's responsibility to deal with players’ account queries (this is the casino’s remit), they should have easy-to-find and accessible contact options for customer support, both from the brands they work with and the end users.
Alongside this, the next-level developers take this ethos further by providing transparency regarding their operations, showcasing ethical practices, and working with external services to pioneer meaningful change outside of the online gaming space, such as fair wage concerns and environmental causes.
Future Trends and Innovations
As you can see, the online slots world has been an exciting place of pioneering developments for over two decades, and it shows no sign of slowing down! With more and more developers entering the market year on year, and companies like Hacksaw Gaming, No Limit City, and many others making a huge mark in just a few years, what comes next is nothing short of exhilarating!
