For a long time, Microgaming was the name behind a large share of the online casino games Canadians played. Mega Moolah, Immortal Romance, Thunderstruck II: all Microgaming. Then, in 2022, the name largely disappeared from game lobbies. The games did not go anywhere. They moved to a new company, Games Global, which now runs Microgaming’s catalogue, its studio partners and the Mega Moolah jackpot network.
This page explains what happened, which games carry the Microgaming legacy, how Mega Moolah works and which Canadian casinos are built on the catalogue.
Quick answer: Microgaming, an Isle of Man company, built some of the first online casino software in 1994. In 2022, Games Global took over its games portfolio, distribution business and progressive jackpot network. So Mega Moolah, Immortal Romance and Thunderstruck II are now Games Global games, and many casinos and reviews still use both names. Super Group’s casinos, including Spin Casino and Jackpot City, are built mainly on this catalogue.

About this list. These are our general picks for players outside Ontario and Alberta, ranked by our overall review score. Some are built mainly on Games Global, while others carry it among many studios. Check the lobby’s provider filter, which may say Games Global or Microgaming. If you live in Ontario or Alberta, play at a provincially licensed site instead (see the section on provincial sites further down).
From Microgaming to Games Global
| Year | What happened |
|---|---|
| 1994 | Microgaming, based in the Isle of Man, develops some of the first online casino software |
| 2006 | Mega Moolah launches and becomes the best-known progressive jackpot slot |
| 2015 | Mega Moolah sets a Guinness World Record with a payout of more than GBP 13 million |
| 2022 | Games Global takes over Microgaming’s games portfolio, distribution business and jackpot network, and launches in May |
After the handover, Microgaming focused on platform services for operators, including Games Global, and continued licensing its sports betting software to Betway. Games Global, licensed in the Isle of Man and the UK, distributes the games and works with dozens of partner studios that release titles under its banner.
For players, almost nothing changed in practice. The same games run in the same casinos, now labelled Games Global. That is why our reviews and many others refer to “Games Global (formerly Microgaming)”. Our overview of online casino software providers shows how it compares with the Evolution group.
Mega Moolah: The Jackpot That Made the Name
Mega Moolah is a progressive jackpot slot with four tiers: Mini, Minor, Major and Mega. A small share of every bet across the whole network of casinos feeds the jackpots, and the Mega tier regularly climbs into the millions before it drops.
Canadian players have hit it more than once. A Canadian won CA$20,059,287 in January 2019, still one of the largest online slot wins on record, and our Jackpot City review documents a CA$16,496,347 Mega Moolah win at that casino in April 2020.
The trade-off is the base game. Because so much of each bet funds the jackpots, Mega Moolah returns roughly 88% in normal play, far below a typical slot. It is a lottery-style game with a real shot at a life-changing prize, not a game to play for value. Our page on progressive jackpot slots explains how to decide whether that trade suits you. Newer WowPot jackpots run on the same Games Global infrastructure, as our Spin Casino review notes.
Classic Microgaming Slots Worth Knowing
| Slot | What it is | Notes |
|---|---|---|
| Mega Moolah | Four-tier progressive jackpot | Base game roughly 88% RTP; jackpot pool separate |
| Immortal Romance | Vampire-themed video slot with four free spins modes | 96.86% published RTP, medium volatility |
| Thunderstruck II | Norse-themed video slot with a multi-level bonus | A long-running favourite |
| 9 Masks of Fire | Scatter-driven video slot | Popular at Games Global casinos |
| Fruit Salad | Simple three-reel classic | 96.90% published RTP |
Immortal Romance is often mislabelled as a NetEnt game. It is Microgaming’s, now Games Global’s. Our profile of NetEnt’s slots covers the games that genuinely belong to that studio. For high-return alternatives, our list of the highest RTP slots compares titles across studios.
Games Global’s Catalogue Today
Games Global combines the Microgaming back catalogue with new releases from its partner studios. In practice that means:
- A deep back catalogue of well-tested, mostly moderate-volatility slots, many of them a decade or more old.
- Progressive networks including Mega Moolah and WowPot.
- Table games, including RNG roulette, blackjack and video poker, plus Real Dealer titles that use filmed dealers, which our Lucky Days review found.
- New releases from partner studios, published under the Games Global banner.
What it does not have is a large live casino of its own. Casinos built on Games Global usually add Evolution for live tables, as our profile of Evolution’s live games covers.
Which Casinos Are Built on Games Global?
The clearest examples are the four Super Group brands we review, all built mainly on Games Global with Evolution for live play:
- Spin Casino: a deep Games Global back catalogue with Mega Moolah and WowPot.
- Jackpot City: the Mega Moolah network plus NetEnt titles, and a documented CA$16.5 million win.
- Ruby Fortune: a smaller library, weighted heavily toward Games Global.
- Royal Vegas: Thunderstruck II, Immortal Romance, 9 Masks of Fire and Mega Moolah.
If you love these classics, that focus is a strength. If you want the newest Pragmatic Play or Hacksaw releases, a multi-studio casino suits you better, as our profile of Pragmatic Play’s slots explains. Many multi-studio casinos also carry Games Global, including SlotsMagic, Spinz, Wheelz, Stake and Dream Vegas, which runs both WowPot and Mega Moolah jackpots.
Games Global at Ontario and Alberta Licensed Casinos
Ontario players can find the catalogue at the regulated Ontario sites of Jackpot City and Spin Casino, which our BetMGM review points to as the alternatives for Games Global fans. bwin and Royal Panda also list Games Global in Ontario. Our overview of Ontario’s licensed online casinos covers the rest. Alberta’s regulated market opened on July 13, 2026, and our page on AGLC-licensed Alberta casinos tracks which brands are live.
Tips for Playing Games Global Slots
- Separate jackpot play from regular play. Mega Moolah’s base game returns roughly 88%, so treat it as a lottery ticket with its own small budget, and play higher-RTP games for everything else.
- Check how the jackpot is triggered. On many progressive games, a bigger bet improves your chance at the top tier. The rules screen explains it.
- Use the back catalogue for steady sessions. Many Games Global classics are moderate volatility, which suits longer play and bonus wagering better than the newest high-volatility releases.
- Confirm the RTP version. As with other studios, the figure in the info screen is the one that counts.
- Use the provider filter. Lobbies may label these games Games Global, Microgaming or by partner studio name, so the filter is the quickest way to find them.
Games Global Slots and Casino Bonuses
Most Games Global slots count fully toward wagering, and the steadier classics are reasonable tools for clearing a bonus. Two exceptions: progressive jackpot games such as Mega Moolah are often excluded or count at a reduced rate, and on some jackpot games a larger bet improves your chance at the top tier. Check the jackpot game’s rules and the bonus terms, as our explainer on welcome bonus terms shows.
Is Games Global Safe?
Yes. Games Global is licensed by the Isle of Man Gambling Supervision Commission and the UK Gambling Commission, and its games are independently certified, as Microgaming’s were. The Mega Moolah jackpots have a long public record of real payouts. As always, play at a properly licensed casino; our explainer on whether online slots are rigged covers what to check.
How We Assess Games Global Casinos
We check how much of the catalogue a casino carries, whether it has the Mega Moolah and WowPot networks, how bonus terms treat jackpot games, whether RTP is shown before you play, and how quickly wins are paid. Our full criteria are in our casino rating methodology.
Chasing a Jackpot Responsibly
A jackpot like Mega Moolah is exciting precisely because the odds of the top prize are tiny. Treat any jackpot play as entertainment with a fixed budget, and never chase a jackpot with money set aside for something else. Our page on problem gambling help in Canada lists support in every province.
