About Microgaming

The Studio That Started It All

Microgaming launched the first functional online casino in 1994 — predating widespread internet adoption — and has since grown into one of the largest slot content networks in the world. Headquartered on the Isle of Man, the studio operates under MGA and UKGC licences and distributes over 800 certified titles across a global network of licensed casino operators.

The company’s most significant ongoing achievement is the Mega Moolah progressive jackpot network, which holds the verified Guinness World Record for the largest online jackpot payout: over €19 million on a single spin. The network feeds from player bets across dozens of licensed casinos simultaneously, creating prize pools that regularly exceed €10 million before they trigger.

Catalogue Depth Over Mechanical Innovation

Microgaming’s catalogue spans every content era of online slots — from five-payline classics to full-featured modern video slots with cascading reels and multiplier mechanics. The breadth is unmatched: 800+ titles covers more mechanical ground than any single player could explore in a lifetime. The trade-off is consistency: newer releases from in-house and third-party partners under the Microgaming network vary significantly in production quality, and older flagships like Thunderstruck II (2010) remain strong despite their age. The studio holds a Megaways licence and has applied it to several titles, though it did not originate the mechanic.

Editor’s Verdict

Microgaming's sheer catalogue breadth and Mega Moolah's record-breaking jackpot network make it impossible to overlook, though many titles show their age against newer HTML5-native studios.
