The best online casino game providers

We’re intrigued by the bonus offers. We’re drawn in by the ease of registration and log in. We’re comforted by the security levels and banking options.

But we stay for the games.

No matter what you prefer or where you’re playing from, the only reason any player spends more than a passing hour or two at an online casino is the games on offer. International online (and mobile) casinos are built to offer more than a land-based casino can possibly bring to the table – thousands and thousands of top quality, thrilling, mesmerising games.

So, where do all these fantastic online casino games come from? While there are hundreds of online and mobile casinos that cater to the needs of the millions of international online gambling fans out there, the games are not actually developed, or even owned, by them. That particular asset is controlled by the game providers.

What are online casino game providers?

Online and mobile casino game providers – also known as game studios – are the super clever and creative folks who design, programme, develop, distribute, and control all your favourite online casino games. Think of them as the movie studios of the gaming industry. The online casinos are like the movie houses or cinemas where you get to watch the movie that that the studio produces and releases. The online casinos give you the chance to play the games that are created by the providers.

Most online casinos license the different games for their players but there are a few casinos who actually have their own in-house studios to create games that are only available at their casino. But these are rare.


How does the provider/casino relationship work?

An online casino is a portal that grants players access to the games. The online casino games are not held on the casino’s servers, they are held by the providers and the casino give the players permission to play the games.

A player logs in to the online or mobile casino. Once verified, the player can choose any game that is being offered by that casino. Once a game is chosen, all play and instructions are sent via the casino’s servers to the provider’s servers and the results are sent back to the casino’s servers and ultimately displayed for the player.

While this may seem a tad labour-intensive, the marvels of modern technology ensure all this happens in microseconds.

Why the complicated to and fro? Security for one. By keeping control of the online casino game, that provider ensures that all players can gamble safely, securely, and with fair play in mind. Nobody can tinker with the game.

A second, just as important aspect is the RNG – the Random Number Generator. The RNG is what tells the game when to stop the reels or what card will be dealt next and is crucial to the online casino world. Because it generates millions of random numbers every second, it is (to all intents and purposes) impossible to affect an RNG and thus makes every online casino game a true game of chance and a game that cannot be hacked and biased.

Why should you care about online casino game providers?

An online casino is only as good as the games it offers. The more games, the more choice, the more players, the more time the players spend at the casino.

Some online casinos are licensed to one specific provider (e.g. Playtech) while others – the bigger, more popular international online casinos – have thousands of games from a wide variety of providers. Personally, the crew prefer the casinos that have more variety, but we do appreciate that those casino with a sole (or maybe two or three exclusive providers) do also offer consistent quality, if not the most exciting of options.

Who are the biggest online casino game providers?

To be clear: we are talking about the BIGGEST players in the industry, not the BEST. Although, size does matter when it comes to the financial power and technical expertise to develop the most innovative and immersive online casino games to date.


One of the (if not THE) original online casino game developers, Microgaming has a long and impressive history in the online casino world.

Founded in 1994, Microgaming claim to be the developers of the first true online casino software – a claim that has never been challenged so there’s that.

Big Time Gaming (BTG)

Big Time Gaming is an Australian online casino games provider who made possibly one of the most monumental changes to how people play slots games (and, in our opinion, created one the greatest versions of online slots game ever) – Megaways™. This Sydney, Australia-based online casino software and games provider shook up the online slots world when they released the first Megaways™ title – Dragon Born – and, since their founding in 2011, have become synonymous with slots innovation and excellence. Megaways™ is licensed to pretty much every big provider and you can now find the incredibly thrilling gameplay being adapted for some of the most venerated slots games in the world, like Gonzo’s Quest. Still, the original BTG offerings are certainly the ones to play regularly, and the studio continues to bring big changes to the online casino industry – Megaclusters and Megaquads, for example.

BTG was acquired by Evolution in 2021 and this should lead to even bigger things for this superb studio.

Most popular BTG online casino games:

  • Any original BTG or licensed Megaways™ game!
  • White Rabbit Megaways™ (just amazing!)

Betsoft, surprisingly, have only been around since 2006. We say surprisingly because they have a huge presence and a huge reputation for a relatively recent studio with ‘only’ 150-odd games on offer. Headquartered in Malta, this is a studio with a serious rep for trustworthiness and reliability. And innovation – they are world renowned for their 3D slots. While online and mobile slots make up the majority of the Betsoft inventory they do often world-class table games (blackjack, pontoon, rummy, red dog, and craps are a few), and localised progressive jackpots (not quite as world-changing wins as wide area progressive jackpots Mega Moolah or Mega Fortune). Betsoft list over 500 online casinos as partners in bringing their games to players worldwide.

Is there any name more synonymous with slots than Bally? All the way back in 1936, Bally began building and supplying the casino industry with the machines that soon began dominating the casino world. Since those early days, Bally has become a rather complicated web of divisions, sub-divisions, partnerships, and holdings. Bally’s Corporation owns a bunch of casinos and hotels. Bally’s Manufacturing seems to build traditional slot cabinets and casino equipment. Bally Technologies Inc is the part that we are interested in though, and they are a big deal in the online slots game. With a home base in Nevada, USA, Bally has been acquired by Scientific Games (as of 2014) but owns and operates several popular online slots games.

Most popular Bally online casino games:

  • Dragon Spin
  • Lady Robin Hood
  • Monopoly Hot Shot
  • James Bond Goldfinger
  • Hot Shot Inferno

Like Bally, Barcrest began as a supplier of physical equipment to land-based casinos. And, like Bally, this brand that began life in the 1960s is now a part of Scientific Games. This venerable company, instantly recognisable to any British punter, is based in Oldham, UK and has moved from the old slots cabinet business into the fast-paced world on online and mobile slots. While many of their games can now be found under the Scientific Games brand, Barcrest still has enough of a reputation to stay a recognisable and trusted provider in the new world of virtual gambling.

  • Rainbow Riches
  • Beetlejuice Megaways™
  • Pearl of the Caribbean

Red Tiger Gaming (RTG)

That iconic snarling red tiger motif that opens up whenever you play a great online slots game is the property of Red Tiger Gaming, a relative newcomer to the online slots world (founded in 2014). While being a ‘spring chicken’ on the scene, RTG have certainly not the bigger players have all the fun and their reputation for action-packed games and fun features has seen them becoming a major force to be reckoned with. The saying ‘never catch a tiger by the tail’ is certainly apt for this Isle of Man-based studio and their attention-grabbing games have led to a 2019 acquisition by industry leaders NetEnt. Not surprising that such an illustrious company would set their targets on this disruptive studio, especially with acquisitions being a big focus of the really big players in the industry over the past 10 years or so, and it’s great to see that NetEnt are giving them the freedom to continue developing their own games as well a collaborate on NetEnt games. Apart from their incredible attention to details like quality graphics and sound, thrilling gameplay, and unusual features, RTG also offer their partners Smart Spins mechanics, regular tournaments, and the Daily Drop Jackpot.

Keep an eye out for 1942: Sky Warrior set to release on Nov 25, 2021. It looks like it’s going to be a game that sets the sky as the limit!

Not quite as young as RTG, Yggdrasil began life in Sweden in 2013 and have become a name that is the epitome of innovation and creativity, Now headquartered in Malta, the studio has lost none of its Scandinavian sense of quality and style. While a small studio (in terms of the rest of the juggernauts on the list), Yggdrasil is proving that size doesn’t matter when it come to creating enthralling and riveting online casino games. With a major focus on online and mobile slots, but with a growing side hustle in tables games, Yggdrasil are bringing life to the online casino industry with a special flavour of fun.

Most popular Yggdrasil online casino games:

But there’s so much more

This is just a taste of who the international online casino games providers are and what they bring to our heavily laden gambling tables. There are more big-name providers out there (IGT, Williams Interactive, Aristocrat) and a slew of superb indie studios making the news (Spinomenal, Booming Studios, and more), and the list of studios allied to or partnered with other studios and operating under there umbrella is truly staggering…


… these are some of the crew’s favourites. In our opinion, the games make the casino, and these providers bring the power and the perks whether through innovative features, incredible bonuses, amazing design, or creativity that just makes us sit back and revel as the reels spin or the cards fall.
