Best Microgaming Slots

Microgaming helped define online slots from the earliest licensed video games and progressive jackpots through to feature-rich 243-ways titles, branded blockbusters and the huge game network now distributed by Games Global. We compared 20 of the best Microgaming-lineage slots across RTP, volatility, maximum wins, Free Spins, jackpot structure and game mechanics to cover everything from early classics to modern WowPot and Megaways releases.

Best Microgaming Slots at a Glance

The name Microgaming now covers two eras for players. The original company built many of online gambling’s most important early slots before selling its game-development assets to Games Global in 2022. Games Global now distributes that historic catalogue alongside new titles from studios including Stormcraft, Triple Edge, Gameburger, Northern Lights and Fortune Factory. You can compare the wider group with other slots software developers in our main provider guide.

What Do You Give Up to Play a Microgaming Progressive Jackpot?

Full Reviews: The 20 Best Microgaming Slots

Immortal Romance

Immortal Romance remains one of the defining Microgaming video slots because its bonus progression gives repeated play a structure. The Chamber of Spins contains four different Free Spins modes that unlock after increasing numbers of bonus triggers, while Wild Desire can turn multiple reels Wild during ordinary play.

Its combination of a 96.86% reviewed RTP, 12,150x maximum and four distinct bonus modes makes it unusually balanced for a high-volatility classic. It remains our overall Microgaming pick for players who want both mathematical value and long-form bonus progression.

Immortal Romance II

Immortal Romance II modernises the same characters without simply rebuilding the first game. Rolling Reels, locking Wilds, growing jackpots, selectable Free Spins and an upgraded Wild Desire feature increase the amount of state that can develop across a sequence.

The sequel can reach 15,000x stake, above the original’s 12,150x reviewed ceiling. It is our choice if you want the Immortal Romance story but prefer modern persistent mechanics and jackpot layers.

Thunderstruck II

Thunderstruck II uses its Great Hall of Spins to reward repeated bonus triggers with increasingly complex Free Spins modes. Valkyrie, Loki, Odin and Thor each change how the bonus plays, culminating in Rolling Reels and multiplier progression.

The game still stands out because these are not merely four cosmetic selections. The mechanics genuinely change, giving long-term players something to unlock rather than repeating the same Free Spins feature indefinitely.

Thunderstruck Wild Lightning

Thunderstruck Wild Lightning pushes the franchise toward collection challenges, feature chasing, multipliers and bonus jackpots. Thor can contribute 2x or 5x multipliers when acting as a Wild, while the Hammer Scatter opens a selection screen containing five Free Spins destinations.

That makes Wild Lightning the better Thunderstruck option for players who prefer several active objectives and jackpot elements, while Thunderstruck II remains the cleaner progression-based classic.

Did Microgaming Sequels Actually Improve the Originals?

Jurassic Park

Jurassic Park remains one of Microgaming’s strongest branded games because each dinosaur changes the Free Spins mechanics rather than merely changing the artwork. The five bonus modes include Wild Reels, Split Wilds, Running Wilds, multipliers and held Wild positions.

The 96.67% reviewed RTP and 6,333x maximum also mean the licence did not come at the expense of an unusually weak mathematical model.

Lara Croft: Tomb Raider

Lara Croft: Tomb Raider is important historically because it helped establish licensed video-game characters as viable online-slot brands. Its structure is far simpler than Jurassic Park, combining 3x Free Spins with a separate Tomb pick bonus.

That simplicity is now part of the appeal. Players wanting a genuine early Microgaming experience without meters, jackpots or multi-stage feature trees should find Tomb Raider much easier to follow than the newer catalogue.

Break Da Bank Again

Break Da Bank Again is one of the defining bank-vault games from Microgaming’s classic period and has proved durable enough for Games Global to keep rebuilding the franchise into newer formats.

The reason it belongs here is not because it has the most complicated mechanics. It represents the older Microgaming approach of building a clear theme around Wild multipliers and Free Spins, then letting those mechanics carry the game without additional persistent systems.

9 Masks of Fire

9 Masks of Fire combines direct Mask scatter prizes with multiplier Free Spins, giving the base game a meaningful prize route before the bonus triggers. The reviewed 96.24% RTP and medium volatility also make it substantially more approachable than the large progressive titles.

It is one of the best examples of Microgaming’s later partner-studio model producing a game that feels modern without becoming mechanically difficult to read.

Unusual Suspects

Unusual Suspects revolves around Sticky Frames whose multipliers can increase as Wilds repeatedly land on the same positions. The Detective Wild then converts those accumulated frames into actual Wild symbols.

Its Free Spins feature adds another progression layer through the Big Boss Trail, which can increase both spin count and multiplier strength. This is our strongest selection for players who like visible persistent progress building over time.

Eggs Bonanza

Eggs Bonanza has the largest fixed maximum in the original 10-game page at 15,000x, but the reason it reaches that ceiling is the density of its modifier system rather than a single huge multiplier.

Egg collection, Chicky Respins and four different bonus modifiers can interact during the Bonanza feature. It is the clearest high-volatility non-progressive choice for players who want a large ceiling without moving into a network jackpot.

Bust the Bank

Bust the Bank is the numerical outlier in the opposite direction. Its reviewed 96.75% RTP is extremely strong, but the stated maximum is only 450x.

The main bonus locks reels one and five Wild throughout Free Spins, making the feature unusually straightforward. It is better suited to players prioritising theoretical return and simple Wild-driven bonuses than those chasing an extreme maximum win.

Does a Higher Microgaming RTP Mean a Smaller Maximum Win?

Mega Moolah

Mega Moolah is Microgaming’s most important progressive jackpot slot and one of the games that made networked online jackpots globally recognisable. The gameplay itself is intentionally uncomplicated, with the four-tier Jackpot Wheel doing most of the work.

Its low reviewed base RTP is the obvious tradeoff. You play Mega Moolah for access to the Mega progressive, not because its ordinary spins compete with Immortal Romance or Thunderstruck II on return.

Mega Moolah: Absolootly Mad

Absolootly Mad gives the Mega Moolah structure a much more involved base game. Rolling Reels create consecutive wins, the multiplier trail grows through sequences and collected Wilds feed a visible teapot meter tied to the jackpot feature.

It therefore solves one of the original Mega Moolah’s biggest weaknesses: players have more to engage with while waiting for a progressive trigger.

Wheel of Wishes WowPot

Wheel of Wishes matters historically because it debuted Games Global’s four-tier WowPot network. The game subsequently produced a €38.46 million top-jackpot win in December 2023, exceeding the previous Mega Moolah online jackpot record.

That makes it the natural pick for players whose only objective is access to the largest demonstrated jackpot ceiling in the current Games Global lineage.

Wolf Blaze WowPot Megaways

Wolf Blaze combines the WowPot network with the changing reel architecture of Megaways. It has also produced repeated multimillion-euro wins, including an €11.8 million payout in 2024.

The combination is important because modern progressives no longer have to rely on extremely simple base games. Wolf Blaze gives jackpot players a much denser reel system while they chase the same network prize.

Mega Moolah Megaways

Mega Moolah Megaways brings the same idea to Microgaming’s best-known progressive brand: keep the Mega Moolah jackpot network but replace the old fixed-payline feel with variable Megaways gameplay.

For players who like the brand but find the original mechanically dated, this is the clearest modern alternative.

Ancient Fortunes: Poseidon WowPot Megaways

Ancient Fortunes: Poseidon WowPot Megaways combines mythology, Megaways and the WowPot network in one title. It is another example of Games Global moving progressive jackpots away from the simple base-game structure associated with early Mega Moolah.

Choose it over Wheel of Wishes if you want more elaborate variable-reel gameplay while retaining access to the same broad WowPot jackpot concept.

Gold Blitz Extreme

Gold Blitz Extreme represents a completely different modern Games Global design trend. Cash symbols carry values, Blitz symbols collect them, persistent tokens improve Rising Rewards jackpot potential, and players can choose between Free Spins and Gold Blitz Super Spins.

The game reaches 5,500x and demonstrates how far the wider Microgaming lineage has moved from single-trigger Free Spins toward persistent collections, cash values, jackpots and selectable bonus modes.

Avalon III

Avalon III revives one of Microgaming’s longest-running fantasy franchises with a much denser contemporary structure. Magic Orbs can award prizes and multipliers, while Jackpot Orbs lead to five jackpot levels and Free Spins Orbs open the bonus.

Its 5,000x maximum is not extreme by modern Games Global standards, but the game is important as a direct example of a classic Microgaming brand being rebuilt around current collection and jackpot mechanics.

WWE Bonus Rumble: Gold Blitz

WWE Bonus Rumble: Gold Blitz shows the modern continuation of Microgaming’s long history with licensed entertainment brands. Instead of copying the old Lara Croft model, however, the game gives players a Bonus Choice between multiplier-driven Free Spins and Gold Blitz Super Spins with guaranteed cash collection.

It is therefore a useful bookend to Tomb Raider: both are licensed games, but their underlying design philosophies are separated by roughly two decades of slot development.

Which Microgaming Slot Should You Play?

Immortal Romance remains our overall pick because its 96.86% reviewed RTP, 12,150x ceiling and progressively unlocked Chamber of Spins still produce one of the most balanced combinations of return, bonus depth and payout potential in the catalogue.

Best Microgaming Slot for Progressive Jackpots

Wheel of Wishes WowPot is the strongest pick if top-jackpot size is the priority, having produced the €38.46 million record WowPot win. Mega Moolah remains the more iconic traditional progressive.

Best Microgaming Slot for Megaways Jackpots

Wolf Blaze WowPot Megaways combines variable reels with the WowPot network. Mega Moolah Megaways is the better choice if you specifically want the historic Mega Moolah brand.

Best Microgaming Slot for High RTP

Immortal Romance leads the mainstream games in this comparison at 96.86%, followed by Bust the Bank at 96.75%, Jurassic Park at 96.67% and Thunderstruck II at 96.65%.

Best Microgaming Slot for High Max Wins

Among non-progressive games with fixed values in this list, Eggs Bonanza and Immortal Romance II reach 15,000x, followed by Unusual Suspects at 12,500x and the original Immortal Romance at 12,150x.

Best Classic Microgaming Slot

Lara Croft: Tomb Raider is our pick for players who want a genuinely early licensed Microgaming game, while Break Da Bank Again is the stronger choice for a classic in-house video-slot experience.

Best Microgaming Slot for Bonus Progression

Thunderstruck II and Immortal Romance remain the benchmark because repeated bonus triggers unlock different feature modes rather than simply retriggering the same bonus.

Best Modern Microgaming-Lineage Slot

Immortal Romance II is the strongest bridge between the old and new eras. It preserves a major Microgaming franchise while adding Rolling Reels, persistent Wilds, jackpots and a higher 15,000x ceiling.
