Microgaming: Where Online Casino Gaming Began
Microgaming claims to have developed the world’s first true online casino software in 1994, making them the oldest active provider in the industry. For over three decades, the company has been a cornerstone of online gambling technology, powering some of the earliest and most recognizable online casino brands.
The company’s most significant contribution to online gambling is undoubtedly the Mega Moolah progressive jackpot network, which has created more millionaires than any other online slot. The game holds multiple Guinness World Records for the largest online slot payouts in history.
In recent years, Microgaming has shifted its strategy from in-house game development to a platform and aggregation model. Through their content aggregation partnerships and exclusive studio deals, they distribute games from dozens of independent studios alongside their own catalog. This pivot acknowledges the changing landscape where specialized boutique studios increasingly compete with legacy providers.
Iconic Microgaming Titles
Microgaming’s legacy catalog spans thousands of games developed over three decades. These are the titles that defined eras of online casino gaming.
Mega Moolah
RTP: 88.12%
The millionaire-maker. Four-tier progressive jackpot that has paid out over 1 billion euros in total. Low base game RTP reflects jackpot contribution.

Vampire-themed narrative slot with four character-based free spin features that unlock progressively. A masterclass in slot storytelling.

Norse mythology sequel with the Great Hall of Spins bonus featuring four tiers of free spin modes. Enduring classic from 2010.
Break da Bank Again
RTP: 95.43%
Bank heist-themed slot with up to 25x multipliers in free spins. Simple, punchy gameplay that has aged well.
Avalon II
RTP: 96.30%
Arthurian legend slot with eight bonus features forming the Grail Quest. One of the deepest bonus structures in any slot.
Microgaming RTP and Jackpot Mathematics
Microgaming’s standard slot titles offer RTPs ranging from 95% to 97%, which is competitive with industry standards. Immortal Romance at 96.86% represents particularly strong value for a high-profile title.
The notable exception is their progressive jackpot games. Mega Moolah’s base game RTP of 88.12% is significantly lower than typical slots because a portion of every bet feeds the progressive jackpot pools. This trade-off is fundamental to how progressive jackpots work: lower base game returns fund the life-changing top prizes.
Players should understand this trade-off clearly. If you are chasing regular returns, standard RTP slots are the better choice. Progressive jackpot games like Mega Moolah are best approached as entertainment with a lottery-like upside, not as a primary gambling strategy.
Casinos with the Best Microgaming Selection
As one of the original online casino software companies, Microgaming games are available at a massive number of online casinos worldwide. Their aggregation platform means that even casinos primarily using other providers often carry Microgaming content.
For progressive jackpot hunters, the specific casino matters less than finding one with a good welcome bonus that allows play on Mega Moolah. Note that not all bonus terms permit progressive jackpot play, so read the conditions carefully.
Classic Microgaming-powered casino brands often carry the most comprehensive catalog of their games, including legacy titles that may not be available at newer operators.
