Games Global Slots & Where to Play Microgaming Games

By Jack Henshaw, Head Writer · Published 4 July 2026 · Last updated 9 July 2026

Games Global is the company that bought online slots’ founding dynasty: created in 2021, it acquired the entire Microgaming portfolio a year later — Mega Moolah, Immortal Romance, the WowPot jackpots and three decades of history, distributed to 900+ operator brands through 40-plus partner studios. Its network holds the largest verified online jackpot ever paid: €38.4 million on a single spin. Our verdict: 8/10. This Games Global review covers the best Games Global slots ranked, the millionaire-making jackpot maths, and where the classic Microgaming slots live now.

The best Games Global slots: 10 games that actually matter

Thirteen hundred-plus games, ten places — weighted toward the titles that built online slots itself, because no other catalogue carries this much history. RTPs quoted are headline defaults. The full ranked catalogue is near the end of the page.

1. Mega Moolah (2006)

The Millionaire Maker — the most consequential slot ever built. A modest safari game wrapped around a four-tier progressive whose Mega pot seeds at a million and has been minting millionaires for twenty years: Jon Heywood’s £13.2m Guinness-record win in 2015, the €19.4m record of 2021, cumulative payouts long past the billion mark. The honest print: its published RTP is 88.12% — the lowest headline figure on this entire site — because roughly six points of every stake feed the dream. Nobody plays it for the base game; everybody knows why they’re there.

2. Immortal Romance (2011)

The vampire soap opera that proved slots could do narrative: four characters, four unlockable free-spin modes in the Chamber of Spins, a brooding soundtrack with an actual cult following, and the Wild Desire feature that can turn all five reels wild mid-drought. Its 96.86% published default made it the thinking player’s staple for a decade, and its 2023 sequel only confirmed the original’s canonisation. The most-loved game Microgaming ever made — and it isn’t close.

3. Thunderstruck II (2010)

The Great Hall of Spins — four Norse gods, four bonus modes unlocked by loyalty (Thor’s Wildstorm arriving only on your fifteenth entry) — made Thunderstruck II the first slot to reward coming back, years before persistence was a genre. At 96.65% published with immaculate pacing, it’s still many veterans’ desert-island slot, and the Remastered edition and Stormchaser sequels keep the hammer swinging. Norse mythology’s finest hour on reels until the Scandinavians took it back.

4. 9 Masks of Fire (2019)

The partner-studio model’s biggest hit: Gameburger Studios’ blazing 20-line game where nine mask symbols trigger free spins with a multiplier gamble wheel. It became a UK lobby fixture overnight, spawned a HyperSpins edition and a small franchise, and demonstrated that the “40 studios, one distributor” strategy could produce modern bangers, not just curate the archive. Published default 96.24%, tempo relentless.

5. Book of Oz (2018)

Triple Edge Studios’ answer to the Book genre — expanding symbols, Oz-flavoured mystique — with a twist the genre needed: buyable respins on any single reel, letting players chase the book directly. The Lock ’N Spin edition refined it further, and the game remains the network’s strongest entry in slots’ most crowded genre. Published default 96.31%.

6. Jurassic Park (2014)

The film-licence landmark of its generation: 243 ways, five dinosaur free-spin modes (the T-Rex Alert mid-game remains iconic), and production values that made 2014’s rivals look prehistoric. Microgaming’s Hollywood era — Terminator 2, Game of Thrones, Playboy — peaked here, and the game’s reverence for its source material set a standard the industry still chases. Published default 96.67% in its day; availability now varies by market.

7. Break Da Bank Again (2008)

The vault-cracking sequel that became a permanent institution: 5x wilds in the base game, up to 25x in the free spins, and a maths profile that taught a generation what “volatile” meant before the word was marketing. Nearly two decades of respins editions and Megaways updates later, the original’s dirty-simple appeal survives intact — the catalogue’s best time capsule of late-2000s slot design. Published default 95.43%.

8. Game of Thrones (2016)

The first Westeros slot — house-sigil free spins (Baratheon, Lannister, Stark, Targaryen, each with its own volatility), the theme music in full, and a braavos coin-flip gamble — released at the show’s cultural peak. A decade later the licence famously moved on (Blueprint’s 2026 Warner Bros. deal now carries the Iron Throne), making Microgaming’s original a collector’s piece of licensing history. Published default 95.05%; the sigil choice remains the fan-service benchmark.

9. Lara Croft: Temples and Tombs (2019)

The modern chapter of slots’ oldest licensing story: Microgaming’s 2004 Tomb Raider was arguably the first major branded slot ever made, and Triple Edge’s 2019 revival honours the lineage with rolling reels and a 3,000x ceiling. As a bookend to fifteen years of brand-slot history — from pixelated pistols to cinematic production — nothing else in the industry compares. Published default 96.01%.

10. Avalon (2006)

The Arthurian workhorse whose 2014 sequel became one of the most acclaimed slots of its era — Avalon II’s quest structure (eight bonus stages advancing toward the Grail) was practically a video game. The original earns the ranking spot as the franchise’s foundation and one of the mid-2000s catalogue’s most durable earners; play the sequel for the adventure, the original for the history. Published defaults around 96%.

Games Global vs the studios it competes with

Games Global’s real peers are empires, not studios. Against our previously reviewed providers:

The honest read: the nineties rivalry never died — Microgaming and NetEnt built this industry between them, and their heirs now compete as an aggregation empire versus an Evolution studio. Modern hit-rate goes to Pragmatic and the volatility studios, and the only comparable full-stack veteran is Playtech, whose Age of the Gods network is the nearest thing to a rival jackpot dynasty; nobody, though, touches Games Global’s jackpot liquidity or its archive. When your network has paid nine-figure lifetime jackpots and holds the all-time record, the catalogue’s unevenness is the price of the crown.

The game families, in depth

Three decades of output organised into dynasties. The full ranked list covers the rest.

The Mega Moolah empire

The 2006 original → Mega Moolah Isis → Summertime → Atlantean Treasures (2020) → Absolootly Mad (payer of the €19.4m record, 2021) → the modern Mega Moolah The Witch’s Moon generation. One shared four-tier progressive across every skin; the Mega pot seeds at a million and averages a life-changing strike every few weeks somewhere on the network.

The WowPot network

The second progressive family — Wheel of Wishes (2019) as flagship, plus WowPot editions of Book of Atem, Sisters of Oz and the Sherlock line — and now the record holder: €38,461,200 on a single Wheel of Wishes spin in December 2023, the largest verified online slot jackpot ever paid, with another $15.8m drop in June 2026. Where Mega Moolah is heritage, WowPot is the growth asset.

The Thunderstruck and Immortal lines

Thunderstruck (2004) → Thunderstruck II (2010) → Wild Lightning and Stormchaser (2021–22, Stormcraft); Immortal Romance (2011) → Immortal Romance II (2023) → the wider Immortal universe. The prestige franchises — the ones the acquisition was really for — now stewarded by Stormcraft Studios with visible care.

The Hollywood archive

Tomb Raider (2004, the first major branded slot) → Playboy → The Dark Knight → Jurassic Park → Terminator 2 → Game of Thrones — the licence shelf that invented the branded-slot business. Many are retired or region-locked now, which makes them the vault: history you can still occasionally find live.

The partner-studio wave

Gameburger (9 Masks of Fire, Hyper Strike), Triple Edge (Book of Oz, Lara Croft), Just For The Win (Deco Diamonds), Slingshot (Wacky Panda), All41, SpinPlay, Pear Fiction and thirty-plus more — the modern production engine, exclusive to Games Global’s distribution. The model: many small kitchens, one enormous restaurant.

Signature mechanics & technology

Games Global’s toolkit is infrastructure first, mechanics second — the empire’s real inventions are networks:

The progressive networks

Mega Moolah and WowPot pool stakes across hundreds of operators into seeded jackpots — the Mega tiers starting at €1m and €2m respectively — with contribution baked into each game’s RTP. This is the original wide-area network model that Red Tiger’s daily pots, Blueprint’s Jackpot King and Relax’s Dream Drop all descend from — and after twenty years it still pays the biggest single sums in the industry.

243 ways

Microgaming popularised the all-ways format — every adjacent combination pays, no lines — through Thunderstruck II and the licence era, and it became the industry’s standard mid-2010s canvas. The format’s DNA is in everything from BTG’s Megaways (243’s variable-reel descendant) to today’s ways-based volatility monsters.

Unlockable bonus progression

The Great Hall of Spins and Chamber of Spins rewarded return visits with new modes years before persistence mechanics had a name — loyalty design borrowed from video games when the rest of the industry was still copying fruit machines.

Quickfire distribution

The 2010s platform that put Microgaming’s catalogue (and hundreds of third-party studios) into practically every casino on earth — the pipes Games Global actually bought. Today it feeds 900+ operator brands; for most UK players, some slice of their lobby arrives through it whether they know it or not.

The partner-studio model

Rather than one in-house culture, 40+ exclusive studios compete for slots on the release calendar — a portfolio approach that trades a recognisable house style for breadth and the occasional breakout (9 Masks of Fire being the model’s trophy). It’s the anti-Push: maximum shots on goal rather than one perfectionist kitchen.

Games Global slots RTP: the real numbers

The defaults: the catalogue spans the industry’s widest range — Immortal Romance at 96.86% and Thunderstruck II at 96.65% at the generous end; modern partner-studio output mostly 96.0–96.3%; and then the progressives: Mega Moolah publishes 88.12%, the lowest headline figure on this site, because the jackpot contribution consumes roughly six points of every stake. That’s not a scandal — it’s the price of the dream, printed honestly — but it makes the paytable check more consequential here than anywhere.

The builds: reduced configurations circulate across the non-progressive catalogue exactly as we document for NetEnt, Pragmatic and the rest — classic titles frequently run below their historic defaults at modern operators. Ten seconds in the paytable tells you whether you’re playing 2011’s Immortal Romance or a leaner 2026 build of it.

Volatility and ceilings: the progressives concentrate essentially all their value in the wheel — base games are deliberately tame, jackpots average one life-changing hit every few weeks network-wide, and the record stands at €38.4m. The heritage catalogue runs low-to-medium; the modern partner output reaches five-figure multipliers without ever chasing Nolimit territory. Jackpot chasing deserves the same discipline as any long-odds bet: our responsible gambling guide applies doubly here.

From the Isle of Man, twice

The arc that matters: the company that invented this industry’s infrastructure — software, progressives, branded slots, distribution — sold its whole legacy to a two-year-old buyer, and the machine didn’t even stutter. The name changed; the pipes, the pots and the millionaires continue.

The people who built the empire

The Microgaming generation

The 1994 Isle of Man founders built in deliberate obscurity — Microgaming stayed private, litigation-shy about its history and famously publicity-averse even while its software ran half the industry. Its great institutional talents were infrastructural: the first progressive networks, the Quickfire pipes, the branded-slot playbook. The individual names never mattered to the company’s mythology; the inventions are the biography.

Walter Bugno & the Games Global builders

Bugno — a gaming-industry veteran of IGT’s international business among much else — leads the 2021-founded acquirer, with a mandate that reads clearly from its actions: consolidate the archive, feed the partner studios, scale the jackpot networks, and take the whole estate public when markets allow (the GGL ticker waits on the NYSE shelf). The 2024 IPO postponement, on his telling, was timing rather than trouble. He is backed by CFO Tim Mickley, previously of SafeCharge and Playtech, and a wider leadership bench Games Global itself frames as “industry legends” — a top table that stayed intact through the October 2025 workforce restructuring even as headcount elsewhere was trimmed.

The forty kitchens

The creative heart is now distributed: Stormcraft stewards the prestige franchises (its Immortal Romance II and Thunderstruck sequels are acts of preservation as much as production), Gameburger supplies the bangers, Triple Edge the polish, and the long tail of exclusive studios everything else. It’s less a studio than an ecosystem with a very famous surname.

Is Games Global fair? Licensing, regulation & the record

Checked against the Gambling Commission’s business licence register on 4 July 2026.

The licences — and the quirk. The Microgaming trading name operates under Apricot Investments Ltd, UKGC account 39073: remote casino and bingo host licences active since November 2014, gambling software since 2015 and betting hosts since 2017 — all Active today. Games Global Operations Ltd’s own account (58841) has since gone live too: Gambling Software and Casino Game Host remote licences, both Active since 15 February 2022 — the modern entity now sits on the register in its own right, not just via the inherited Apricot Investments licences. Verify both on the UKGC public register. Beyond Britain: Isle of Man heritage licensing, and Malta Gaming Authority coverage via Prima Networks Limited (licence MGA/CRP/926/2021, issued 28 February 2022) among further regulated-market certifications.

The record. Clean where it counts: no UKGC enforcement action against the licensed entities that we can find across a decade-plus of the modern register. The jackpot networks’ integrity record is arguably the industry’s strongest trust asset — twenty years of independently verified seven- and eight-figure payouts, including a Guinness-certified record, every one honoured.

So is it fair? Yes — certified RNG across the current 1,300+-game proprietary catalogue, audited progressive pools with the most-scrutinised payout history in gambling, and published figures for everything. The caveats deserve bold print here: Mega Moolah’s 88.12% is the industry’s steepest honest price tag, jackpot contributions thin every progressive’s base game, and heritage titles often run reduced modern builds. All of it is in the paytable; read it before the safari.

The biggest Games Global wins

No other provider’s records page reads like this — these are the largest sums in online slot history. Documented events only:

On tape: a £2.77m Mega Moolah strike as it happened, and Immortal Romance’s Wild Desire at full max:

Videos embedded for illustration — results shown are the players’ own, and the Mega wheel spins for one visitor in millions.

Beyond the reels

The corners of the story the ranking competitors never reach:

The primacy argument

“The first true online casino software, 1994” is Microgaming’s founding claim — contested by rivals’ historians for thirty years, never displaced. What’s beyond dispute: Cash Splash (1998) was the first online progressive, Tomb Raider (2004) the first major branded slot, and the wide-area jackpot network the single most copied piece of infrastructure in igaming. Whoever was technically first, the blueprint was theirs.

The billion-euro drumbeat

The progressive networks’ lifetime payout long ago passed the billion mark, with a life-changing Mega strike landing every few weeks somewhere on earth for two decades — a cadence of manufactured millionaires no lottery-adjacent product in gambling matches. The €38.4m record will fall eventually; the machine that produced it is the real record.

The name that outlived its company

“Microgaming” persists in lobbies, player memory and even the UKGC register (as a trading name of Apricot Investments) years after the business behind it was sold and renamed — the rare brand strong enough to survive its own corporate death. Games Global’s quiet dilemma is visible in its own marketing: the new name owns the assets; the old one still owns the recognition.

Westeros, twice sold

Microgaming’s 2016 Game of Thrones slot defined the licence era’s peak; a decade later the Iron Throne signed with Blueprint under Warner Bros. Discovery’s 2026 deal. Two eras of the same licence, two different empires — and a neat measure of how the industry’s centre of gravity moved from the Isle of Man to the licensing war chests of the volume studios.

The company behind the games

Games Global describes itself as “established in 2022” on its own About Us page — the year the Microgaming acquisition actually completed, distinct from the 2021 date the acquiring vehicle was formed. The company is led by CEO Walter Bugno alongside CFO Tim Mickley, and its UK arm, Games Global Operations Limited, now carries its own Active UKGC licences (account 58841) rather than trading solely through the inherited Apricot Investments entity. Beyond Britain, the group’s Maltese arm, Prima Networks Limited, holds a Type 1 Gaming Services licence from the Malta Gaming Authority (MGA/CRP/926/2021, issued 28 February 2022) — one of several regulated-market certifications the official site lists alongside its UK and Isle of Man coverage.

The partner roster has grown well beyond the original Microgaming-era names since the acquisition: Games Global’s own Studios page now lists more than 30 named exclusive studios across Europe, Africa, North and South America and Australia, from familiar faces like Stormcraft and Gameburger to newer additions such as Foxium, All For One Studios, High Limit Studios and On Air Entertainment (the last of these supplying live-casino content to operators including Videoslots and Mr Vegas). It is a genuinely different shape of company to the one that completed the 2022 handover — smaller in raw game count after 2025’s restructuring, but broader in studio reach and now licensed in its own right rather than purely on inherited paperwork.

New Games Global slots: what’s launched for 2025–26

The state of Games Global right now: the partner machine at cruising speed, the jackpots compounding, the IPO still on the shelf — and, since our last check, a leaner operation: an October 2025 global workforce restructuring cut headcount to roughly 840 staff, which CEO Walter Bugno framed as proactive rather than defensive, and the proprietary catalogue itself now sits at a curated 1,300+ titles rather than the 3,000+ inherited at the 2022 handover. None of it has slowed the release calendar: Games Global’s own July 2026 roadmap adds more than 20 further titles across its studio network. This section refreshes with every significant launch.

All ship with published figures; progressives carry their jackpot contribution within them. Paytable first, always.

What players actually say

From two generations of forums — because no other provider has players who remember 2004. Our words, cons intact.

The love: the jackpot dream, above all — Mega Moolah winners’ stories are the genre’s folklore, and every €38m headline recruits another wave of believers. Immortal Romance and Thunderstruck II command genuine multi-generational devotion (the soundtrack fandoms are real), the archive’s depth rewards explorers, and veterans credit the old house with inventing half of what everyone else now does.

The gripes, plainly: the 88.12% on the ticket, first and loudest — informed players regard Mega Moolah’s base game as the most expensive waiting room in gambling. The 1,300-plus-game catalogue is still described, fairly, as an ocean of filler around islands of brilliance; the partner-studio output lacks a recognisable soul; beloved licensed classics vanish into rights limbo without warning; and nostalgics grumble that the new owner’s name means nothing to them. All true — and the queue for the wheel never shortens.

Our verdict on Games Global

Slot Providers score: 8/10 — the inherited empire: gambling’s greatest jackpot machine, its most storied archive, and a partner model that trades soul for scale.

Games Global suits jackpot dreamers, slot historians, franchise loyalists and anyone who wants the deepest catalogue in the industry behind one name. Look elsewhere if you want a house style — Hacksaw and Push offer identities this empire deliberately traded away — or honest-generous maths, where Relax’s 99% experiment sits at the opposite pole from the Moolah’s 88. And before any safari: the paytable states the price of the dream in black and white.

Games Global FAQs

Is Games Global the same as Microgaming?

Effectively, yes — for players. Games Global (founded 2021) bought Microgaming’s entire games portfolio and Quickfire distribution business in May 2022, inheriting Mega Moolah, the classics and the partner-studio network. Microgaming survives as a trading name on the UKGC register under Apricot Investments Ltd.

Who owns Games Global?

It’s a private-capital-backed company led by CEO Walter Bugno. An IPO was filed on the NYSE under ticker GGL in 2024 and postponed; the company remains private as of mid-2026.

Is Games Global fair, or are its games rigged?

The jackpot networks have twenty years of independently verified payouts — including a Guinness-certified record — certified RNG runs across the current 1,300+-game catalogue, and the UK licences (accounts 39073 and 58841, both Active) carry a clean modern record. The honest caveats are in the maths: Mega Moolah publishes 88.12% because of its jackpot contribution.

What is the biggest Games Global jackpot ever won?

€38,461,200 on a single Wheel of Wishes spin (WowPot Mega) on 20 December 2023 — the largest verified online slot jackpot ever paid. Mega Moolah’s record is €19.4 million (2021), and a further $15.8 million WowPot dropped in June 2026.

Why is Mega Moolah’s RTP so low?

The published 88.12% includes roughly six percentage points of jackpot contribution — every spin funds the four-tier progressive. You’re buying a lottery ticket stapled to a slot; the paytable prices it honestly.

What is the best Games Global slot?

Mega Moolah is the most consequential, Immortal Romance the most loved, Thunderstruck II the veteran’s pick and 9 Masks of Fire the modern staple. Our full ranked ten, with reasoning, is above.

What happened to the old Microgaming licensed slots like Game of Thrones?

Licensed titles retire or region-lock as rights lapse — Jurassic Park, Terminator 2 and Game of Thrones availability now varies by market, and the Thrones licence itself moved to Blueprint under Warner Bros. Discovery’s 2026 deal.

Who are Games Global’s partner studios?

Forty-plus exclusive studios including Stormcraft (the Thunderstruck and Immortal lines), Gameburger (9 Masks of Fire), Triple Edge (Book of Oz, Lara Croft), Just For The Win, Slingshot, All41, SpinPlay and Pear Fiction.

Did Microgaming really launch the first online casino?

It has claimed since the nineties to have shipped the first true online casino software in 1994 — a claim rivals dispute and nobody has displaced. Indisputably its firsts: the first online progressive (Cash Splash, 1998) and arguably the first major branded slot (Tomb Raider, 2004).

What are the newest Games Global slots?

2026 has brought Baozang the Legend of 3 Coins and Wacky Panda Power Combo, alongside the continuing Immortal Romance II rollout. Full slate in our new releases section.

Where can I play Games Global slots in the UK?

Betway, 32Red, Unibet, LeoVegas, Videoslots, Casumo, 888casino and William Hill are among the well-known UKGC-licensed operators confirmed to carry Games Global content, including the King Millions™ and Mega Moolah™ jackpot networks. See our full UKGC casinos section for the details, and always verify any operator on the Gambling Commission register before depositing.
