The Best Microgaming Slots and Where to Play Them: TOP Microgaming Casinos

Operational for over 30 years, Microgaming is a legendary game studio with an exceptional back catalogue that includes some of the finest casino games ever made.  

But which are the best Microgaming slots of all time, and where can you play them in 2025? Join us as we introduce you to the best of the Microgaming lobby, some newer Games Global releases, and the top-rated UK casinos that stock these games in 2025.  

Who is Microgaming?  

Microgaming was established in 1994 on the Isle of Man. In the following decades, it grew into one of the largest and most successful slot machine developers, responsible for iconic games like Mega Moolah. Microgaming also holds the record for the biggest slot machine payout, over £13 million, in 2015.  

Microgaming is now part of the Games Global group, which includes 20+ partner studios and over 1,300 games. While Microgaming occasionally releases new slots, the latest games are from Games Global partner studios, as we reveal below.  

Still, Microgaming has an enviable back catalogue of legendary online casino slots, several of which are progressive jackpot titles. Below, we introduce the best Microgaming slots of all time.  

The Best Microgaming Slots of All Time   

Microgaming has released over 200 games since 1994, and since being swallowed into the Games Global machine, the collaborative platform is now responsible for 1,300+ titles available at the best slot sites. So, with that in mind, we’ve gone back in time to look at the most iconic slots in the Microgaming back catalogue.  

Our editor’s view: “It’s impossible to write about Microgaming without introducing you to the ‘millionaire maker,’ Mega Moolah. There are now numerous Mega Moolah slots in the franchise, but I love the original, set on the African plains. I also love Thunderstruck II and Immortal Romance, two classic slot games that will never get old. Below are my recommendations for Microgaming slots to play at top UK casinos in 2025.” 

Mega Moolah (2006)  

• RTP: 93.42% 

• Maximum win: Progressive   

• Volatility: Low  

When a slot is known colloquially as “the millionaire maker,” you should sit up and take notice. Mega Moolah has created more millionaires than any other slot game, so if you’re searching for huge progressive payouts, this is the Microgaming slot game for you. 

Immortal Romance (2011)  

• RTP: 96.86%  

• Maximum win: 12,150x  

• Volatility: Very high  

The Twilight of the online slot machine world, Immortal Romance is a vampire-themed five-reel slot with prizes of up to 12,000x the bet available. The Chamber of Spins round is the highlight, offering modifiers, multipliers, and up to 25 free spins, depending on which character triggers it.  

Thunderstruck II (2010) 

• RTP: 96.65% 

• Maximum win: 8,100x  

• Volatility: Low  

Starring Valkyrie, Loki, Odin, and Thor, Thunderstruck II is the Norse mythology slot all other developers have tried to emulate over the years. The Great Hall of Spins is where the big wins are, offering lucky players payouts of up to 8,100x the bet.  

Terminator 2 (2014) 

• RTP: 96.62% 

• Maximum win: 2,952x  

• Volatility: Medium  

“I’ll be back.” You certainly will, if you’ve ever spun the reels on this iconic slot, based on Arnold Schwarzenegger’s hit movie. The medium volatility keeps things ticking along, and the excellent free spins round increases the ways to win from 243 to 1,024, helping you to form winning combos.  

9 Pots of Gold (2020)  

• RTP: 96.24% 

• Maximum win: 2,000 

• Volatility: Medium 

A collaboration between Microgaming and Gameburger delivered one of the finest luck of the Irish slots of all time, 9 Pots of Gold. This classic Irish slot doesn’t try too hard, but the free spins wheel adds excitement when the bonus round is triggered, allowing you to unlock a huge multiplier to crank up any bonus round payouts.  

Book of Atem: WowPot (2020)  

• RTP: 93.50% 

• Maximum win: Progressive  

• Volatility: High  

Though not quite as explosive as the Mega Moolah series, the WowPot jackpot games are worth playing. The Egyptian-themed Book of Atem is the pick of the bunch, with an ever-growing progressive jackpot and numerous special features, including a special expanding wild to help you form winning combinations. 

Break Da Bank Again (2008)  

• RTP: 95.43% 

• Maximum win: 37,575x  

• Volatility: Medium  

This quirky money-themed slot from Microgaming is notable for its huge max payout of 37,575x the bet. This is courtesy of an excellent free spins bonus round, which delivers up to 25 spins and multipliers that can increase all wins by up to 25x your stake.
