Best Microgaming Casinos 2026
About Provider: Microgaming
Microgaming has a fair claim to having started the whole industry. It launched what is widely credited as the first online casino software in 1994 and spent the next three decades building one of the largest slot libraries anywhere. The name most players know it for is Mega Moolah, the progressive jackpot that has paid record-breaking sums and turned a handful of players into millionaires off a single spin.
In 2022 the company rebranded its distribution arm as Games Global, and much of what carries the Microgaming legacy now runs through a network of independent studios rather than a single in-house team, similar to how Relax Gaming and Yggdrasil operate partner platforms. The back catalogue is enormous, with classics like Immortal Romance, Thunderstruck II, and Avalon still in rotation at most casinos.
The downsides come with the size and age. Mega Moolah’s base-game RTP is low, often in the high-80s to low-90s, because so much of the return funds the jackpot, so you are paying for the lottery dream. Many catalogue titles are dated, and the sprawl since the Games Global rebrand makes quality less predictable than a focused studio like Nolimit City. The jackpots are the genuine draw. The rest is a mixed library.
RTP & volatility
Microgaming RTPs vary widely. Standard slots run around 96%, but the Mega Moolah jackpot games sit far lower, often high-80s to low-90s, because a large slice of the return feeds the progressive pool. If you chase the jackpot, you accept a worse base-game return for the shot at a life-changing payout.

The progressive jackpot king through Mega Moolah, plus legacy classics like Immortal Romance and Thunderstruck II. One of the oldest studios in the industry, now distributing through the Games Global network.
Top games
Mega Moolah is Microgaming's progressive jackpot slot and the most famous in the world, holding records for some of the largest online casino payouts ever. The catch is the base game: the reels themselves are simple and the RTP is low, because much of the return funds the jackpot pool. You play it for the jackpot wheel, not the base spins.
Effectively yes. In 2022 Microgaming sold its distribution business, which was rebranded as Games Global, and the games now flow through that network of partner studios. Many casinos and players still use the Microgaming name out of habit, and the legacy catalogue, including Mega Moolah, carried over.
Because a large share of every bet feeds the progressive jackpot rather than the base-game payouts. That pushes the standard RTP down into the high-80s to low-90s on the jackpot titles, well below a normal slot. It is the price of the chance at a multi-million payout, and it is why these are dream-chasing games rather than grinders.
For the jackpot dream, Mega Moolah is the obvious one. For an actual slot to sit and play, Immortal Romance and Thunderstruck II are the classics that still hold up, with better base-game returns than the jackpot titles. Newer hits like 9 Masks of Fire are a faster, more modern alternative.
Many are, honestly. A lot of the catalogue dates back years and shows it next to the snappy output of Hacksaw Gaming or Nolimit City. The classics like Immortal Romance age well, but plenty of the library feels old, and the Games Global rebrand spread quality across a wider, less predictable set of partner studios.
