Every giant industry has an origin story, and iGaming’s begins with Microgaming. This is the company that built what many call the first real online casino, back in 1994, before most people had heard of the internet. Then it created Mega Moolah, the jackpot slot that has turned more everyday players into millionaires than any other game in history.
In 2022 the story took a twist, when the legendary catalogue passed to a company called Games Global. Same games, same jaw-dropping jackpots, new custodian. If you have ever dreamed of one lucky spin changing your life, this is the lineage that made the dream feel possible.
The quick version
- Provider type: Aggregator and Game Studio network, with platform roots.
- Founded: 1994, on the Isle of Man.
- Claim to fame: Built one of the first online casino platforms ever made.
- Signature creation: Mega Moolah, the record-breaking jackpot slot.
- The 2022 handover: Its game catalogue and studios moved to Games Global.
- Studio network: Content from more than 40 independent studios under one roof.
Where this lineage sits in the four provider types
Mainly an aggregator today
Today, Games Global is best understood as an Aggregator. Through the old Quickfire platform, it gives operators one connection to a massive library built by dozens of separate studios. Plug in once, get thousands of games. For an operator, that single hookup replaces what would otherwise be dozens of separate studio deals. It is the textbook aggregator role, and it is how most casinos access this catalogue.
A studio network and a platform past
It is also a Game Studio in the plural, since more than 40 independent studios create the content it distributes. And Microgaming, the original entity, has deep Platform Provider roots, having built casino software since the very beginning. So this one name touches three of the four boxes, which says a lot about how far back it goes.
The company that invented the online casino
A genuine first
Microgaming set up on the Isle of Man in 1994 and did something nobody had done properly before: it put a casino on the internet. Its first product ran as software you downloaded to your computer, a format that shaped the whole industry for the next decade. This is not marketing spin. It is genuinely where a huge amount of it started.
One first after another
It kept breaking new ground. In 1998 it launched Cash Splash, the first networked progressive jackpot, where players across many casinos feed one shared prize pool. In 2003 it helped found an independent body dedicated to fair-play certification. In 2010 it launched Quickfire, letting operators plug into a huge library through a single connection. This is a company that set trends rather than following them.
Mega Moolah, the millionaire maker
The four-tier jackpot
If one game defines this lineage, it is Mega Moolah. Released in 2006 with a cheerful African safari theme, it features four tiered jackpots called Mini, Minor, Major, and Mega, and that top one is the stuff of legend. It seeds at one million and climbs relentlessly until a lucky spin sets it free.
Numbers that do not look real
The figures are staggering. Mega Moolah has paid out well over one billion in jackpots across its lifetime and created more than two thousand documented millionaires. One single spin once landed a prize north of eighteen million, which earned a Guinness World Record for the largest online slot payout at the time. A different lucky player later banked more than nineteen million.
The catch worth knowing
What makes it work is the shared pool. Because contributions come from players on countless casinos, the jackpot grows to sizes no single site could fund alone. There is one trade-off, though. Jackpot slots run at a lower RTP than standard games, often in the high eighties to low nineties, because so much of every bet feeds that giant prize. You are swapping everyday returns for a shot at life-changing money.
WowPot and the jackpot family
A second network
Mega Moolah is not the only game in town. Inspired by its own success, the network launched WowPot in 2020, a second progressive jackpot whose top prize seeds at two million and can rise indefinitely. WowPot has since paid out enormous sums of its own, giving players a second flavour of the millionaire dream.
One dream, many themes
Both jackpots are woven into a whole family of themed slots, so you can chase Mega Moolah in a safari game or WowPot in an Egyptian adventure like the popular Book of Atem. That flexibility is clever. It keeps the jackpots fresh by attaching them to new themes and mechanics, rather than trapping players in one aging game.
The 2022 handover to Games Global, explained
What actually changed
Here is where new players get confused, so let me make it plain. In 2022 Microgaming sold its entire game distribution business and its famous catalogue to a company called Games Global. Games Global now manages the legendary titles, the jackpot networks, and the network of independent studios that create the games.
What it means for you
The Microgaming name did not vanish. It still appears on the progressive jackpot networks, and the original entity refocused on platform technology. For a player, the takeaway is simple. When you see Games Global listed as a provider, you are looking at the same catalogue that carried the Microgaming badge for years. The games did not change. Only the nameplate on the office door did.
The studio collective behind the catalogue
Many hands, one flag
The modern model is powered by many hands. Rather than one central team building everything, the games come from a roster of more than 40 independent studios, each with its own personality. Together they release several new games every week, keeping the catalogue fresh and enormous.
The names doing the building
All41 Studios, based in Estonia, built hits like Book of Atem and the first Megaways title in the family. Gameburger Studios serves big, bold, US-style slots including the 9 Pots of Gold line. Stormcraft Studios, Triple Edge Studios, Neon Valley Studios, and PearFiction Studios each add their own flavours, from the wonderfully named Absolootly Mad: Mega Moolah to darker, quirkier fare. It is less a single studio and more a creative collective flying one flag.
The classic slots hall of fame
The cult favourites
Beyond the jackpots, this catalogue holds some of the most beloved slots ever made. Immortal Romance is a cult classic, a moody vampire romance with 243 ways to win and a devoted following that keeps playing years after release. Thunderstruck and Thunderstruck II brought Norse mythology and Thor to the reels, complete with retriggerable free spins and the famous Great Hall of Spins.
Blockbusters and healthy returns
The lineup runs deep with names like Avalon, Break da Bank Again, and 9 Masks of Fire. Microgaming also loved a blockbuster licence, turning big brands into slots over the years, from Jurassic Park to Tomb Raider. Most of these classics run at a healthy RTP in the 96 to 97 percent range, and plenty still hold their own against far flashier modern releases.
Live dealer games too
The OnAir Entertainment studio
Slots and jackpots are the headline, but this lineage reaches into live casino as well. Games Global delivers live dealer content through OnAir Entertainment, its dedicated live studio brand, with roulette, blackjack, and game show style tables streamed from professional studios. It is a smaller operation than Evolution’s, yet it means an operator can pull slots, jackpots, and live tables from the same supplier. The live range has grown steadily since launch, with new tables and formats added to keep pace with demand. For players, it is one more reason the Games Global name turns up in so many corners of a casino.
A timeline of firsts
Few companies can point to a track record of genuine industry firsts. This lineage can, and its milestones read like a short history of online gambling itself.
- 1994: Microgaming builds one of the first online casinos, using downloadable software.
- 1998: Cash Splash launches as the first networked progressive jackpot.
- 2003: Microgaming helps found an independent fair-play certification body.
- 2006: Mega Moolah arrives and starts minting millionaires.
- 2010: The Quickfire platform opens the catalogue to operators through one connection.
- 2020: WowPot launches, and the family ships its first Megaways slot.
- 2022: Games Global acquires the distribution business and the catalogue.
Is it safe and fair?
Built on tested math
Yes. This is one of the most established lineages in the business, and it operates under regulated licences with independently tested games. Microgaming helped create one of the earliest fair-play certification bodies, so a respect for tested, transparent math has been in its DNA from the start.
Heavily audited jackpots
The jackpot networks in particular are heavily audited, which matters when pools climb into eight figures. A trusted, certified provider means the eye-watering prizes on the posters are real and genuinely winnable, even if the odds of triggering the big one are, understandably, very long.
Where you will run into it
All over the place, often under the Games Global or Microgaming name, and sometimes under the badge of one of the individual studios. If a casino advertises Mega Moolah or a networked jackpot in the millions, this is the lineage behind it. The catalogue supports many currencies and regulated markets, so it turns up across a huge spread of casinos worldwide, from the UK to the Baltics to Latin America.
The bottom line
Few names carry this much weight. Microgaming built the foundations of online casino gaming and created its most famous jackpot, and Games Global now keeps that legacy alive and growing across dozens of studios. For players, that means access to real history, one of the deepest game libraries anywhere, and a genuine shot at the jackpot that made the whole industry dream a little bigger.
A lot of what you enjoy about online casinos traces back, in part, to this lineage. It wrote the first chapter, then wrote the biggest jackpot, and it is still adding pages today.
