About Microgaming

Microgaming was founded on the Isle of Man in 1994 and launched the world's first functional online casino, Gaming Club, in the same year. The software they built to power that casino became the foundation of the online gambling industry. Every technical convention that subsequent studios inherited, from the random number generator certification process to the client-server architecture that allows regulated play across jurisdictions, was pioneered by Microgaming when no regulatory framework yet existed to mandate it.

Mega Moolah (2006) is the most commercially significant slot in the history of online gambling. The progressive jackpot pools contributions from players across every connected operator globally and paid a verified $23.6 million to a single player in 2021, a world record for an online slot jackpot. Immortal Romance (2011) and Thunderstruck II (2010) are the studio's strongest non-jackpot titles and remain among the most-played medium-volatility slots in the library, notable for storyline depth and character continuity across sessions.

Microgaming's active development pace has slowed significantly since their peak years, with the studio now focused primarily on their progressive jackpot network and their Quickfire aggregation platform, which distributes games from dozens of third-party studios to operators. Their Ontario AGCO supplier licence covers the five SlotVault titles: Mega Moolah, Immortal Romance, Thunderstruck II, Game of Thrones, and Avalon II. These are catalogue titles representing the peak of Microgaming's first-party creative output.

Microgaming Signature Mechanics

Mega Moolah's Progressive Network
Mega Moolah pools jackpot contributions from every connected operator globally, creating a prize pool that grows continuously until it triggers. The jackpot must pay before reaching an operator-configured ceiling, ensuring it always pays eventually. The $23.6 million 2021 payout is the verified record.
The Original Online Casino
Microgaming did not enter the online casino market: they created it. Gaming Club, launched in 1994 on Microgaming's proprietary software, was the first online casino to accept real-money wagers. No other studio on SlotVault has a comparable foundational claim.
Immortal Romance's Storyline Depth
Immortal Romance (2011) features four playable characters with individual backstories, relationships, and distinct free spins bonus rooms unlocked progressively across sessions. The vampire romance narrative unfolds through bonus triggers and character progression in a way that no contemporary slot attempts at equivalent scale.

Frequently Asked Questions

How does the Mega Moolah jackpot work?
Mega Moolah has four progressive jackpots: Mini, Minor, Major, and Mega. All players across all connected operators globally contribute to the same pot. The Mega jackpot is won via a Jackpot Wheel that can trigger on any spin at any stake. A higher stake increases the chance of triggering the wheel but does not affect the wheel's prize probabilities. The jackpot must pay before reaching a configured ceiling.
What is the base RTP of Mega Moolah?
Mega Moolah has a base game RTP of 88.1%. This reflects the proportion of stakes diverted to the progressive jackpot pool. The effective RTP including jackpot probability is closer to 96%, but the jackpot component is paid as a single winner-takes-all event rather than distributed evenly across sessions.
Are Microgaming slots available in Ontario?
Yes. Microgaming holds AGCO supplier approval and their full SlotVault catalogue is available on all AGCO-licensed Ontario platforms for players aged 19 and over.
What happened to Microgaming development?
Microgaming has significantly reduced their first-party slot development pace since the mid-2010s. The company now focuses primarily on the Mega Moolah progressive jackpot network and their Quickfire platform, which aggregates and distributes third-party studio games to operators. Their five SlotVault titles represent peak-era first-party releases from 2006 to 2014.
How many bonus rooms does Immortal Romance have?
Immortal Romance has four distinct free spins bonus rooms, one for each of the four main characters: Amber, Troy, Michael, and Sarah. They unlock sequentially: Amber's room activates after 5 bonus triggers, Troy's after 15, Michael's after 25, and Sarah's after 35. Each room has a different mechanic and increasing max win potential.
