Microgaming Slots: Best Games, RTP and Max Wins
As of 2022, Microgaming is operating under Games Global’s UKGC license (account number 58841). As we’ll mention in this guide to the best Microgaming slot games, plenty of operators have adapted the wording to reflect this massive change better. In short – if you can’t find Microgaming as a provider at your chosen site, look for Games Global instead.
Since its founding in 1994, Microgaming has produced more than 500 slots, but a big part of its portfolio isn’t available in UK casinos. The more accurate number would be closer to 100, although some sites offer barely half or fewer.
This provider boasts international renown as the creator of the Mega Moolah slot, the developer of various unique mechanics like Blazing Reels, and a brand with more than 30 years of industry experience. In this guide, we’ll showcase some of the most popular Microgaming slot machines and help you learn where to find them.

What Are the Best Microgaming Slots?
The title of the “Best” Microgaming slot is largely a matter of subjective preference. High-RTP slot fans likely won’t be as enthusiastic about Mega Moolah as jackpot hunters, just like heavy volume players wouldn’t waste much time on Microgaming slots with low exposure limits.
We’ve tested household names and emerging UKGC licensed slot sites to see if they had all the biggest Microgaming hits, and this is what we’ve found:
| Slot | Release Year | Max RTP | Volatility | Max Win | Min Stake | Where to Play |
|---|---|---|---|---|---|---|
| Thunderstruck 2 | May 2014 | 96.65% | Medium | 8,000x | £0.3 | bet365 |
| Immortal Romance 2 | May 2024 | 96.30% | High | 15,000x | £0.1 | Monster Casino |
| Break Da Bank Again Megaways | August 2021 | 96.05% | Very High | 19,560x | £0.2 | Bluefox Casino |
| Mega Moolah | November 2006 | 93.42% | Low | 1,955x | £0.25 | betMGM |
| Agent Jane Blonde Max Volume | January 2022 | 96% | Medium | 10,000x | £0.25 | 32Red |
Thunderstruck 2
Thunderstruck II is a massive hit among British gamblers, courtesy of basic but exceptionally helpful in-game bonuses. For starters, all Wilds not only substitute for other symbols, but also multiply all connected wins by 2x. Any spin can trigger the “Thunderstorm” effect, when up to 5 reels become Wild Reels.
Moreover, every time you draw 3 or more scatters, you’ll enter the Free Spins round. Re-entries into the “Great Hall of Spins” will fill a progress bar and help you unlock better free spins modifiers.
Immortal Romance 2
Built in collaboration with Stormcraft Studios, Microgaming’s Immortal Romance 2 is a sequel to one of its most successful slot machines.
From character jackpots and Wild Desire Multipliers to the random-trigger Jackpot wheel, Multiplier Wilds, and Locking Wilds, this is one of the most action-packed slots in Microgaming’s portfolio.
Break Da Bank Again Megaways
Break Da Bank Again Megaways brought dynamic reels to an already feature-rich game. With Rolling Reels on every win, RNG-based paylines that change in count on every spin, and an extra reel at the top of the standard grid, this slot is well-suited for fans of games with exceptionally high variance.
Mega Moolah
Cartoonish graphics, a relatively humble maximum win limit, and low variance might be the first things you notice about Mega Moolah, until you look at the progressive jackpot counters. This is the very slot machine that led to one of the biggest single-spin wins in the UK’s history and is among the first titles jackpot hunters look for when browsing lobbies of Microgaming casino sites.
Agent Jane Blonde Max Volume
Agent Jane Blonde: Max Volume is a fixed jackpot slot with a barrage of multiplier-based features. Free spins with Multiplier Trails and Rolling Reels make it a popular choice for beginners and seasoned spinners alike.
What Are the Newest Microgaming Slots?
Unlike prolific studios like Hacksaw, Nolimit, and Pragmatic, Microgaming usually releases one new slot every few months. We counted barely a handful of fresh releases in 2026, so let’s take a quick look at the best new Microgaming slots:
| Slot | Release Date | RTP | Volatility | Max Win |
|---|---|---|---|---|
| Pocket Ace | March 2026 | 96.03% | Medium | 10,000x |
| Horse’s Treasures | January 2026 | 96.20% | Medium | 10,000x |
| Olympus Storm | January 2026 | 96.33% | High | 5,000x |
| Golden Cat Fortunes | October 2025 | 96.20% | Medium | 2,000x |
| Cash Blitz Extreme | October 2025 | 96.20% | High | 25,000x |
Note: This table was last updated on October 23rd 2026.
Slots List: Which Titles Can You Play in the UK?
You can play more than 100 Microgaming slots in UK-licensed casinos. Most of them can be found by applying the “Video Slots” filter, including recent releases like Olympus Storm, Pocket Ace, and 12 Skulls of the Dead.
Microgaming jackpots are often displayed among “Featured” or “Top Picks,” as you’ll recognise when you spot thumbnails or game cards for hits like Mega Moolah, Immortal Romance, or Sweet Jar Combo.
Make sure to use the Search tool to look for specific Microgaming titles if you can’t find the brand under “Providers.” Plenty of UKGC-regulated casino sites offer Microgaming slots with “Games Global” being credited as the developer (it acquired Microgaming in May 2022).
Which Microgaming Slot Series Are the Most Popular?
This studio has plenty of “uncategorised” games – slots that don’t belong to any particular group or franchise. However, seasoned and inexperienced gamblers alike are likely to recognise the names of these super-popular slot series:
- Mega Moolah: What started with one of the most impactful British jackpots eventually became a jackpot network, which houses smash hits like Immortal Romance Mega Moolah and Thunderstruck II Mega Moolah.
- Immortal Romance: Apart from the classic Immortal Romance dilogy and the Mega Moolah adaptation of this game, the Immortal Romance series received a few spin-offs, with the most notable being Moonlight Romance: The Awakening.
- Pop Culture and Branded Games: Some of the aforementioned “uncategorised” slots made by Microgaming share a link with iconic pop culture movies and TV shows, such as Game of Thrones, Jurassic Park, and Terminator.
What Features Do Microgaming Slots Use?
Slots made by this provider don’t use a uniform set of bonus features. There are Microgaming Megaways, fixed jackpots, progressives, slots with cascading (Blazing) reels, low-exposure slots that accept 10p bets, as well as extremely volatile games that an average budget couldn’t sustain. Explore our reviews of the best Microgaming slots to discover how some of its most heavily acclaimed features work.
Which Microgaming Slots Have the Highest RTP?
Microgaming has developed a handful of slots with excellent Return to Player scores (over 97%), with the highest RTP being set for Party Island (97.50%). The provider’s portfolio includes dozens of games with RTPs of over 96%, but more than a few have below-average figures of 92-93%. Here’s a table of Microgaming slots with the strongest RTPs:
| Slot | RTP |
|---|---|
| Summer Holiday | 97.14% |
| Olympus Storm | 96.33% |
| 12 Skulls of the Dead | 96.40% |
| Lucky Twins Wilds Jackpots | 96.20% |
| Moonlight Romance: The Awakening | 96.20% |
| Diamond Diva Oink Bonanza | 96.20% |
| Bountiful Birds | 96.20% |
| Monkey’s Treasure Quest | 96.20% |
| Almighty Poseidon Empire | 96.20% |
| 3rd Base | 96.20% |
Does Microgaming Release Slots With Different RTP Versions?
Microgaming RTP values are fixed on the provider’s official website, and all Microgaming titles we found on Games Global’s site follow suit. We found no evidence that UK-licensed operators use different RTP builds. However, it’s worth noting the huge difference between the lowest and highest RTPs in the provider’s slots; while the figures average around 92-96%, some titles in the brand’s portfolio may have lower scores when you account for jackpot RTP contributions.
Which Microgaming Slots Have the Biggest Max Wins?
High-volume players are typically not interested in Microgaming max win slots – they go for Mega Moolah or WoW Pot progressives instead. Games from these categories are linked to massive prize pools, and any eligible spin may trigger a hefty win.
If you’ve chosen a site that doesn’t support Microgaming’s jackpot franchises, you may find some of these Microgaming slots more than suitable alternatives:
| Slot | Max Win | Volatility |
|---|---|---|
| Merlin’s Secret Maxways | 40,000x | High |
| Cash Blitz Extreme | 25,000x | High |
| Immortal Romance 2 | 15,000x | High |
| Royal Thunder Riders | 10,000x | High |
| Bountiful Birds | 10,000x | Medium |
| Gold Infinity | 10,000x | High |
| Crazy Bob Bonanza | 10,000x | High |
| Gold Saloon Cash Blitz | 10,000x | High |
| Grand Casino Heist | 10,000x | High |
| Circus Jugglers Jackpots | 10,000x | Medium |
| African Guardians | 10,000x | High |
How Volatile Are Microgaming Slots?
Microgaming volatility ranges from low to very high – the provider doesn’t specialise in any particular area of slot variance. Most Microgaming slot titles have medium volatility (62) or high variance (35), while fewer than a dozen slots in its portfolio are games with either low or very high variance ratings:
- Very High Volatility: Gold Blitz Extreme, Lucky Leprechaun Clusters, Break Da Bank Again Megaways
- High Volatility: Olympus Storm, Cash Blitz Extreme, 12 Skulls of the Dead
- Medium Volatility: Moonlight Romance: The Awakening, Lucky Twins Wilds Jackpots, Genie’s Magic Wishes
- Low Volatility: Mega Moolah, Money on Reels Super Arrow, Party Island
Does Microgaming Have Jackpot Slots?
Microgaming is the provider behind one of the largest progressive jackpot franchises in the UK gambling space – Mega Moolah. In fact, some of the world’s biggest jackpot wins have hit on this very slot, including a record-breaking £13,213,838.68 by Joe Heywood in 2012.
Plenty of the brand’s flagships were reimagined as Mega Moolah Microgaming jackpot slots, albeit with slightly different stats. For example, the Thunderstruck II Mega Moolah slot has a slightly lower RTP of just 92.01%. Here are some of the other famous jackpots from the Mega Moolah series:
- Mega Moolah The Witch’s Moon – 93.42% RTP
- Mega Moolah Goddess – 93.30% RTP
- Fortunium Gold Mega Moolah – 92.80% RTP
- Atlantean Treasures Mega Moolah – 92.08% RTP
- Juicy Joker Mega Moolah – 92.03% RTP
- Absolootly Mad Mega Moolah – 92.02% RTP
Where Can You Play Microgaming Slots in the UK?
Apart from all the sites we mentioned in our Microgaming slots lists, there are plenty of other UK-licensed online casinos that offer games from this provider. However, only a handful of platforms (like Foxy Casino or Monster) still use Microgaming’s brand name in their provider filters; most others lump Microgaming slots with the games from the casino family that acquired it in 2022, Games Global.
After testing and reviewing more than 50 fully regulated platforms, we concluded that these are some of the best Microgaming casinos UK:
| Casino | Number of Microgaming Slots | Welcome Offer | Minimum Deposit |
|---|---|---|---|
| 7bet | 100+ | Deposit £20 Get 100 Bonus Spins | £10 |
| 32Red | 75+ | Play £30 Get 320 Free Spins | £5 (Debit Card only) |
| Monster Casino | 30+ | Welcome Package Up To £1000 + 100 Free Spins | £10 |
Who is Microgaming?
Microgaming is a long-running slot developer founded in 1994. It was acquired by the Games Global casino family in 2022, and it’s been operating under its UKGC license ever since. The brand is still producing new games, often by collaborating with other Games Global brands, although its presence in UK casinos is somewhat limited compared to the rest of the world.
How Does Microgaming Compare With Other Slot Providers?
Microgaming has a significantly longer track record than most slot developers we consider trendy these days. However, Microgaming’s portfolio can’t come close to the 800-some games in Pragmatic’s library. Play’n GO offers a bit more stable RTP range in its games, while Blueprint’s Jackpot King is one of the biggest rivals of Microgaming’s Mega Moolah series.
| Provider | Known For | Signature Mechanic | Typical RTP Range |
|---|---|---|---|
| Microgaming | Mega Moolah record-breaking jackpot win | Hyperspins, Rolling Reels, Progressive Jackpot Bars | Around 92-96% |
| Blueprint Gaming | Fishin’ Frenzy progressive jackpot network | Cash Collection, Megaways | Around 94-95% |
| Play’n GO | Unique slot mechanisms and strong slot themes | Blitzways (Play’n GO Megaways), Go Guaranteed Hold & Win prizes | 94.50-96.50% |
| Pragmatic Play | Big Bass series, hailed as one of the most prolific slot developers | Cascading Wins, Cluster Pays, Random Wilds/Multipliers, Megaways | Around 96.50% |
