About Microgaming
Microgaming launched the world's first online casino software in 1994, making them the pioneer of the entire online gambling industry. Headquartered on the Isle of Man, Microgaming developed the first mobile casino software in 2004 and created the first progressive jackpot network that produced the record-breaking €17.9 million Mega Moolah payout in 2015.
In 2021, Microgaming transitioned its game development to the Games Global platform, which now operates as an independent company managing the Microgaming content network. This means the iconic games continue to be available at Irish casinos under the Games Global umbrella, with access to 3,000+ titles from 50+ independent studios.

Mega Moolah is the undisputed king of progressive jackpots. The network regularly builds to €5-15 million before dropping. Immortal Romance and Thunderstruck II are among the most beloved mid-volatility slots ever created, with deep bonus mechanics that reward extended play sessions.

Microgaming Progressive Jackpot Network
The Games Global progressive jackpot network connects hundreds of casinos worldwide into shared prize pools. Beyond Mega Moolah, the network includes Major Millions (minimum €250,000 jackpot), Treasure Nile, and King Cashalot. The network has paid out over €1.5 billion in total progressive jackpot winnings since its inception.
To be eligible for the progressive jackpot, you typically need to trigger the bonus wheel feature during gameplay. While the jackpot can technically be won on any bet size, higher bets increase the probability of triggering the wheel.
