Meet The Best MicroGaming Slots of All Time

If Pragmatic Play is the flashy new disruptor on the block, Microgaming is the venerable grandfather who owns the entire neighborhood. They’ve been around since 1994—back when “the internet” was something you accessed via a screeching phone line and a prayer.

However, if you’re looking for “Microgaming” in a casino lobby today, you might be confused. In 2022, the company sold its entire legendary back catalog and distribution rights to a powerhouse called Games Global.

The Microgaming Legacy: A Giant Reborn as Games Global

While the Games Global portfolio boasts over 800 slots, they don’t actually build most of them in-house anymore. Instead, they act like a massive record label for “boutique” indie studios. When you play a “Microgaming” slot today, you’re likely playing the work of a specialized team like:

  • Stormcraft Studios: The wizards behind the Immortal Romance and Thunderstruck sequels.
  • Triple Edge Studios: The high-gloss team responsible for the Game of Thrones and Ancient Fortunes hits.
  • Neon Valley Studios: The experts in “Vegas-style” high-energy slots.
  • All41 Studios: The ones pushing the boundaries with modern mechanics and high volatility.

The Hall of Fame: 10 Best Microgaming (Games Global) Slots

1. Immortal Romance (The Original & Remastered)

The Twilight of the slot world, but with much better math. This vampire-themed soap opera has been a staple since 2011. Its “Chamber of Spins” and the “Wild Desire” feature (which can turn all five reels wild) are the stuff of legend. It’s moody, the soundtrack is unironically great, and the 12,150x potential is still terrifyingly relevant.

  • Best for: Players who want a story with their spins.

2. Mega Moolah

The “Millionaire Maker.” This is the most famous progressive jackpot slot in history. The graphics look like they were drawn in MS Paint in 2006, but nobody cares when the Mega Jackpot is sitting at £12 million. It’s low volatility in the base game, but you aren’t here for the lions; you’re here for the wheel.

  • Best for: Jackpot hunters who don’t mind a low RTP in exchange for a lottery-sized win.

3. Thunderstruck II

If Immortal Romance is the moody teen, Thunderstruck II is the rugged older brother. Based on Norse mythology, it introduced the “Great Hall of Spins” and remains one of the most balanced slots ever made. It’s a medium-volatility masterpiece that proves you don’t need 100,000 ways to win to have a good time.

  • Best for: Purists who want a “perfect” slot experience.

4. 9 Masks of Fire

Produced by Gameburger Studios, this game started an industry-wide obsession with “Epic Strike” (scatter jackpot) mechanics. Land 9 masks, get 2,000x your stake instantly. It’s simple, the rhythm is hypnotic, and it’s currently one of the most-played games in the UK.

  • Best for: Players who want instant gratification and clear goals.

5. Game of Thrones (243 Ways)

Unlike most branded slots that are lazy cash-grabs, this one actually delivers. You choose your House (Stark, Lannister, etc.) during the free spins, each offering a different combination of multipliers and stacked symbols. It’s brutal, much like the show, but the “gamble” feature allows you to flip a coin through Westeros for extra wins.

  • Best for: Fans of the show and players who like choosing their own volatility.

6. Ancient Fortunes: Poseidon Megaways

Created by Triple Edge Studios, this is Microgaming’s answer to the Megaways craze. It combines the 117,649 ways to win with a “Rolling Reels” mechanic and a progressive jackpot picker. It’s polished, underwater-themed, and feels much more “modern” than the old-school classics.

  • Best for: Megaways fans who want a chance at a jackpot on any spin.

7. Jurassic Park

Another branded hit that aged like a fine wine (or a well-preserved mosquito in amber). The “T-Rex Alert” mode adds 35 wilds to the reels, and the five different free spin modes based on dinosaur DNA are genuinely creative. The parallax scrolling backgrounds were revolutionary at the time and still look great.

  • Best for: Nostalgia seekers and fans of high-quality licensed content.

8. Break da Bank Again

This is a “high-variance” dinosaur. It’s a 9-line slot where the multipliers are the star—wins in the free spins are multiplied by 5x, and if a Wild is involved, it’s 25x. It’s simple, it’s fast, and it can drain your bankroll or break the bank in a matter of minutes.

  • Best for: Old-school “hardcore” players who hate flashy animations.

9. Assassin’s Moon

Developed by Triple Edge Studios, this features the “Link&Win” mechanic that Games Global has pushed heavily. It’s a slick, Bond-esque spy thriller where collecting six moon orbs triggers a “Hold & Win” bonus. It’s high production value and very high volatility.

  • Best for: Fans of the “Hold & Win” mechanic (popularized by Wolf Gold).

10. Wolf Blaze WowPot! Megaways

If Mega Moolah is too “retro” for you, the WowPot! series is the modern alternative. This North American wilderness-themed slot offers the “WowPot!” jackpot, which often starts at £2 million. It’s a Megaways engine with a massive jackpot attached—the ultimate “best of both worlds.”

  • Best for: Players who want modern features but still want to chase the “Big One.”

What Else You Should Know (The Expert “Gotchas”)

1. The “800+ Game” Illusion
Games Global has a massive library, but let’s be honest: about 500 of those are “filler” games from 2008 that no one plays anymore. Don’t get overwhelmed by the numbers. Stick to the “Partner Studios” listed above for the best experience.

2. The Jackpot RTP Penalty
When you play Mega Moolah or WowPot! games, a significant chunk of your RTP (Return to Player) goes toward funding the jackpot. This means the “base game” RTP might only be around 88-90%. You are paying a “tax” for the chance to win millions. If you aren’t chasing the jackpot, play the non-jackpot versions instead.

3. The “Link&Win” Obsession
Games Global has leaned heavily into the “Link&Win” mechanic (where you collect symbols to reset a 3-spin counter). It’s their version of Pragmatic’s “Hold & Spin.” If you’ve played one, you’ve played them all—only the theme usually changes.


The Verdict

Microgaming (Games Global) is the “Legacy Act” that actually still knows how to rock. While they rely heavily on their partner studios to keep things fresh, their back catalog contains the most iconic games in history. Whether you want the cinematic storytelling of Immortal Romance or the life-changing potential of Mega Moolah, this is a portfolio that every serious slot player needs to explore.
