Blockbuster Titles 

The creative force behind some of gambling’s definitive titles, Microgaming has consistently produced games that have gone on to become firm fan favourites. Games like Mega Moolah, Immortal Romance, and Book of Oz are regularly found at the best online casinos. In addition to its themed games, Microgaming also produces a range of branded titles featuring iconic movie franchises like Jurassic World, Terminator, and Game of Thrones, which are only available at Microgaming online casinos.

Bumper Jackpots 

The progressive jackpots available at Microgaming casinos have paid a collective £1.1 billion since its inception. This collection of games often features several multi-million-pound jackpots at any one time and boasts the most diverse range of progressive jackpots in the industry. It also has a history of record-breaking jackpot wins, including the first-ever mobile slot millionaire in 2013 and a then-world record payout of £16.4 million in 2018.

Huge Range of Games 

The company specialises in slot titles, but that doesn’t mean that is all Microgaming casino sites does. With over one hundred different themes, Microgaming’s titles cater to everyone. So Microgaming has got you covered whether you’re after branded slots with mega jackpots, realistic casino games or a simple virtual scratchcard.

Top 10 Microgaming Slots Ranked

The 10 best Microgaming slots in 2026

These are the ten Microgaming slots our team rates highest in the UK market. Selections weigh RTP, max-win potential, bonus quality and longevity — most of these titles have been earning their place in UK lobbies for over a decade.

1. Mega Moolah

The slot that built Microgaming’s reputation. The base game RTP is poor (88.12%) but the jackpot network is what brings players back: over £1.6 billion paid out in lifetime jackpots and the Guinness World Record for largest online slot win (£19.4m, UK player Jon Heywood, 2018).

2. Immortal Romance

Microgaming’s most-played non-jackpot slot for over a decade. The Chamber of Spins bonus structure was years ahead of its time — players unlock progressively better free-spin modes by triggering them repeatedly. The vampire-romance theme has aged better than most 2010s slots.

3. Thunderstruck II

The Norse-mythology cult classic. Same progressive-bonus structure as Immortal Romance, with each Great Hall mode offering different multiplier mechanics. Still ranks in the top-10 most-played UK slots more than 15 years after release.

4. Book of Oz

Microgaming’s answer to Book of Dead. Wizard of Oz theme rather than ancient Egypt; same expanding-symbol mechanic in free spins. Triple Edge Studios produced it under the Microgaming network. Solid mid-tier RTP and a clean modern build.

5. Avalon II: The Quest for the Grail

The most ambitious bonus structure in any Microgaming slot. Eight progressively-unlocked Grail Bonuses each play out as a mini-game with different mechanics — a precursor to the modern “story slot” trend. Underrated.

6. Game of Thrones

The licensing coup of its era. Players choose their House at the start of the bonus round, with each house offering different free-spin counts and multipliers. RTP is on the low side (95%) but the licensed branding pulls casual players in.

7. Jurassic World

The film-licensed sequel to Jurassic Park. Higher RTP than the original at 96.67%, with the Indominus free-spins round adding split-symbol wins that double the ways-to-win count. The licensing budget shows in the production values.

8. Wheel of Wishes (Mega Moolah variant)

The most accessible Mega Moolah variant. Higher base RTP than the original Mega Moolah (93.34% vs 88.12%) and a more reliable trigger via the Power Mode feature, which guarantees a jackpot wheel spin within a set number of base spins.

9. Atlantean Treasures Mega Moolah

Mega Moolah meets cascading reels. The base game runs Atlantis-themed cascades; jackpot triggers route to the standard Mega Moolah four-tier wheel. A modern entry point to the network for players who find the original Mega Moolah dated.

10. Break Da Bank Again

The longest-running classic in Microgaming’s portfolio. Three-reel-style payline structure, 5x wild multipliers, and a heist theme that’s stayed relevant. Still a top-10 fixture at most UK casinos that carry the legacy Microgaming catalogue.

Microgaming slots and RTP — what to know

RTP — Return to Player — is the theoretical percentage of total wagered money a slot pays back over millions of spins. Most modern Microgaming slots cluster around the 96% mark, but the studio’s catalogue has notable outliers in both directions: a handful of titles above 97%, and the Mega Moolah jackpot network well below 92%.

Caveat: as with most major studios, Microgaming licenses some slots in multiple RTP versions. Always check the in-game info or paytable to confirm what your casino is serving.

If you’re playing for value rather than chasing the headline jackpot, Loaded (96.99%) and Couch Potato (97.43%) lead the catalogue. If you want a balance of high RTP and modern bonus features, Immortal Romance and Thunderstruck II remain the safest bets. Avoid Mega Moolah for value-driven play — the sub-90% base RTP is the price you pay for the jackpot network.

Microgaming’s signature features and mechanics

Microgaming’s identity isn’t built on a single mechanic the way NetEnt’s is on Avalanche or Pragmatic’s on Tumble. The studio’s signatures are distribution-side: the biggest jackpot network in the industry, the deepest licensed-IP catalogue, and a track record of bonus-round innovation that other studios have copied repeatedly.

The Mega Moolah jackpot network

Launched in 2006, Mega Moolah is the largest progressive jackpot network in online gambling. Every Mega Moolah-eligible slot at every UKGC-licensed casino feeds into the same pool, which means jackpots build faster and pay bigger than any single-casino jackpot. The network has paid out over £1.6 billion in lifetime jackpots and produced the Guinness World Record for largest online slot win — £19.4 million to UK player Jon Heywood in 2018, on a 25p stake.

Network titles include the original Mega Moolah, Wheel of Wishes, Atlantean Treasures Mega Moolah, Absolootly Mad Mega Moolah and several others. Base-game RTPs vary (88.12% to 93.34%) — the trade-off for jackpot eligibility.

Branded-slot pedigree

Microgaming has held more major film and TV slot licences than any competitor over the past 15 years: Game of Thrones, Jurassic Park, Jurassic World, Tomb Raider, Lord of the Rings, Highlander, Battlestar Galactica, Hellboy, Bridesmaids, Hitman, Hot Shots. Branded slots typically run lower RTPs than original IP (the licensing fees come out of player payback) but the production values are higher and the brand recognition pulls casual players in.

Multi-modal bonus structures

Immortal Romance, Thunderstruck II and Avalon II all use a progressive-unlock bonus structure: free-spin rounds come in multiple flavours (named after characters or themed locations), each with different volatility and feature behaviour, and players unlock the better ones by triggering the bonus repeatedly. This format predates modern “feature ladder” slots by nearly a decade and remains one of the most rewarding bonus structures in any slot category.

The Cash Splash heritage

Microgaming launched the world’s first online progressive jackpot in 1998 (Cash Splash). The technology that powered it — jackpot-pool aggregation across multiple casinos — is the foundation every modern progressive jackpot is built on. Mega Moolah is its direct descendant.

The Games Global transition — what changed and what didn’t

In May 2022, Microgaming finalised the sale of its online games portfolio to Games Global, a newly-formed distribution company built around the Microgaming catalogue. The deal was significant: the original Microgaming studio wound down its B2B casino-software arm, and the games themselves moved under Games Global’s distribution.

What this means for players

From a UK player’s perspective, the change is mostly behind-the-scenes. The slots are the same, the jackpots are the same, the branded-IP licensing continues. When you select “Microgaming” as a filter at a UK casino lobby today, you’re filtering the Games Global-distributed catalogue — which is largely the legacy Microgaming portfolio plus new releases from Games Global’s network of partner studios.

Who actually makes “Microgaming” slots now

Games Global doesn’t build slots itself — it distributes games made by a network of independent studios that historically supplied Microgaming. The biggest names in the network include:

• Just for the Win — producers of Book of Oz, Wheel of Wishes
• Stormcraft Studios — Atlantean Treasures Mega Moolah, Fortunium Gold
• Triple Edge Studios — Book of Atem, Hyper Strike
• Pulse 8 Studios — Adventures of Doubloon Island
• SpinPlay Games — high-volatility branded titles

The original Microgaming studio’s in-house releases (Immortal Romance, Thunderstruck II, the original Mega Moolah) remain in the catalogue and are unchanged.

What players should watch

Release pace under Games Global has been slower than Microgaming’s pre-2022 cadence, and the catalogue has felt thinner in the last 18 months. The flagship jackpot products (Mega Moolah variants, branded slots) are still being released, but innovation in mechanics has lagged competitors like Pragmatic Play and Hacksaw Gaming. Worth bearing in mind when comparing studios — the Microgaming-pedigree catalogue is deep, but the new-release pipeline is no longer the industry leader it once was.

Progressive Jackpot Slots By Microgaming

The progressive jackpots at Microgaming casinos are connected throughout the network. This implies that many players from several casinos contribute to the prize pools. As a consequence, the jackpots grow fast and are frequently won.

Mega Moolah is the most well-known Microgaming jackpot. This massive prize may be won by playing Mega Moolah Summertime, Mega Moolah, Mega Moolah Isis, The Dark Knight, and Mega Moolah 5 Reel Drive.

These jackpots are accessible on both classic three and 5-reel video slots. Your chances of winning the jackpot are the same regardless of your selected slot game.

• Mega Moolah – A progressive jackpot slot game from Microgaming, Mega Moolah has made more millionaires than just about every other slot game in the world. It has five reels and twenty-five pay lines and is set in the African safari. In addition to doubling rewards, the game offers up to 30 free spins with a 3x multiplier.
• Book of Atem – The Book of Atem WowPot is a book about the god Atem. WowPot slot machine is a simple game. It features a typical ancient Egyptian theme and frequently utilized free spins with expanding symbols feature ubiquitous in slot machines. The WowPot Jackpot feature, which may be triggered at random when a player collects a sufficient number of wild scatters, is the most rewarding one, with jackpots reaching well into six figures.
• Queen of Alexandria: Wow Pot – Queen of Alexandria: WowPot is one of two progressive jackpot variants of the slot machine. The slot has ten active lines on 5×3. The game’s combos may pay 1,000 for the bet, various progressive jackpots, and the WowPot. It will have a Progressive Wheel, increasing wilds and respins.
• Immortal Romance – This 5×3 slot grid has the potential to pay off big. Playing with four characters across 243 pay lines, normal wilds, the Wild Desire Feature, and four separate free spin rounds. Unique elements and even higher prizes await you each time you unwrap the love tale.

One thing worth noting is that the prize figure is not modified in accordance with the majority of major currency conversion rates. For example, if you win a jackpot worth one million credits while playing in Pounds Sterling, you will be paid. However, you would be paid in Euros if you win a jackpot worth one million credits while playing n Euros.

Microgaming Slots Megaways

Microgaming slots have made a partnership with BTG (Big Time Gaming) and incorporated BTG’s online casino software, Megaways, in a few of their slot games. Microgaming collaborates with its group of independent game developers to include Megaways in new products developed just for the Microgaming platform. Shamrock Holmes is the first game that came out of their collaboration.

Microgaming Games - My Top Slot Picks 

A fresh Microgaming slot game is usually a major event in the world of gaming. They are the masterminds behind some of the most popular and successful slot machine releases. A total of more than 750 games are available for you to pick from.

Here are my highlights of this developer’s games, including its most popular titles as well as Microgaming slots with progressive jackpots.  These games have captured the public’s attention because of the life-altering sums that they pay out. The selected games that follow, in my opinion, are the best Microgaming online slots for 2026:

Immortal Romance

This online slot game is a video game about vampires and love that was released in 2011. It’s still a delightful slot because of the combination of a fascinating backstory, top-notch gameplay, and the possibility of large payouts. Free spins are available in 4 distinct variations, each of which is based on one of the game’s four major characters. Each feature has a unique modifier, such as a 5x or 6x multiplier, rolling reels, or wild symbols that turn into other symbols.

There’s also a Wild Desire feature, which may randomly offer you five entirely wild reels, and an RTP that’s much above the industry standard at 96.86%. You may earn as much as 12,500 times your bet on a single play with the Immortal Romance slot game.

Mega Moolah 

Mega Moolah is perhaps the most popular online slot game of all time and has made multiple millionaires since its introduction in 2006. Players can play for a number of progressive jackpots by spinning the game’s five reels in search of one of 25 pay lines. The record jackpot from the African Savannah-themed slot game is a £16.4 million win back in 2018.

Thunderstruck II

Another of Microgaming’s iconic titles is Thunderstruck II, the latest rendition of the classic game. Players try to strike one of the game’s 243 pay lines to win up to £480,000. It also has a number of bonus games in which potential payouts are multiplied or players are awarded a number of free spins.

A 5-reel, 243-way-to-win slot, Thunderstruck 2 is filled with bonuses. The Wildstorm feature, introduced in 2010, may add up to 5 wilds at random to any spin. You’ll find four ways to win free spins in the Great Hall of Spins. They reward anything from 10 to 29 free spins, each with a 5x multiplier, additional wilds, symbol changes, and a set of rolling reels to enjoy.

Slots based on sagas from Scandinavia have proven to be quite successful throughout the years. Win up to 8,000 times your bet with Thunderstruck 2, and the game’s RTP is set at 96.65%. If you like this new edition of the Microgaming portfolio, then why not try the original game, Thunderstruck?

Terminator 2

Microgaming’s Terminator 2 slot perfectly fits the iconic movie it celebrates. Thanks to a remastering effort by the development team, it’s been updated for the 2022 release with new graphics and sound effects. It offers many excellent features, such as 243 chances to win on 5 reels.

The T-800 Vision function, which gives cash rewards for any high-value symbols shown, is one of the extras available here. When you activate the Free Spins feature, you’ll get ten free spins on a slot machine with 1,024 possibilities to win. The RTP of the Terminator 2 slot machine is a respectable 96.62%. With a hit frequency of 43.67% (almost half of all spins result in a win), you may win up to 2,952 times your entire bet from each free spin.

Jurassic World

This Jurassic Park sequel uses a 5-reel, 243-ways-to-win game engine with stunning graphics and features. Free Spins come with multipliers up to 7x, scatters that also work as wilds, and rolling reels. It has a 95.45% RTP and a 31.09 percent hit frequency. A single spin may return up to 14,166 times the investment.

Wheel of Wishes 

Wheel of Wishes was the first game to feature the Microgaming four-tiered Wowpot progressive jackpot. Since its launch in early 2020, it has paid out over £26 million in jackpot wins. The Arabian Nights-themed game features immersive visuals, an enticing soundtrack and gripping gameplay, with players spinning five reels hoping to land one of ten pay lines. Players also have a chance to activate the jackpot bonus game, in which they’ll spin the Wheel of Wishes to win one of four progressive jackpots. The record previous win was £284,531 won in February of 2020.

Boost Your Bankroll with a Bonus

Bonuses allow you to try out a new online casino without the need to gamble with your own money. With free spins, matched deposits, and no-deposit schemes, you can test out a new brand to see if it is one you would like to use going forward.

Free Spins

Free spins are amongst the most common offers new customers can get their hands on and are great for slot lovers. It’s commonplace to see free spins attached to other signup offers like a cash or free bet bonus, but they do sometimes come as a standalone perk. Free spins have wagering requirements attached to them, game restrictions, max winnings limits and withdrawal restrictions.

Therefore, you should ensure you understand the terms and conditions before signing up. It’s also worth noting that free spins aren’t always exclusive to new signups, as some casinos will occasionally reward loyal customers with a few cost-free plays. So keep an eye on offers and promotions pages to ensure you don’t miss out.

Matched Deposits

Matched deposit bonuses are some of the welcome offers available to new customers. Casino sites will match a new customer’s first deposit in bonus funds up to a certain amount. It is common to see a first deposit matched by 100% up to £100, doubling the size of your cash pot. Like most offers, matched deposit bonuses almost always have wagering requirements. This means you may have to play through the value of your bonus a set number of times before you can withdraw any potential winnings.

No Deposit

These promotions reward new customers with free spins, usually on a select number of low-stake slots, without the need to pay anything into their account. All that’s required is that new signups verify their accounts in order to claim risk-free plays. No deposit bonuses commonly come with time limits within which they can be claimed and played. After the time is up, you’ll no longer be able to access them.

Play Microgaming Titles on the Go

Microgaming software is designed to integrate seamlessly with any third-party gaming system. This means it’s compatible with a number of different formats and platforms, including HTML5 and native Android and iOS mobile apps.

Since 2004, Microgaming has been a significant producer of mobile real-money slots software, having been one of the first game developers to enter the mobile gaming industry.

Microgaming currently provides over 400 games that are optimized for playing on any mobile device, including mobile play on Android, iPhone, and other popular devices. These games are available by downloading native applications and instant-play casinos that run HTML5.

Try Out a New Casino

If you’re looking for a new Microgaming casino, consider some of the newer names in the industry. To compete against more established names, new casinos can potentially offer a greater gaming experience and better-value promotions. Features like bumper signup bonuses and favourable reward schemes can make fresh casino sites a desirable option.

Summary

It is clear that there are a number of different options when choosing an alternative Microgaming experience. Whether you like a particular game, payment method, withdrawal parameter, or any other feature of Microgaming, I am confident that within my selections, there is another brand that can offer a similar gambling experience.

Frequently Asked Questions

Responsible gambling

Online slots are designed to be entertainment, not income. Set a budget before you start, never chase losses, and only gamble with money you can afford to lose. All UK-licensed casinos are required by the UK Gambling Commission to offer a range of tools to help you stay in control:

Deposit limits: set a daily, weekly or monthly cap so you can’t deposit more than you’ve decided to spend.

Loss limits and session limits: automatically log out or stop play after a set time or loss amount.

Reality checks: on-screen reminders showing how long you’ve been playing and how much you’ve spent or won.

Time-out and self-exclusion: short cooling-off periods, or — through GamStop — full self-exclusion from every UKGC-licensed casino in the UK simultaneously.

Note for jackpot players: Mega Moolah-eligible slots run a base RTP of 88–93%, well below the 96% industry standard. The trade-off for the network jackpot is a long-run house edge that’s significantly worse than non-jackpot slots. Plan your bankroll accordingly.

If your gambling stops being fun, free, confidential help is available 24/7 from BeGambleAware or the National Gambling Helpline on 0808 8020 133.

You must be 18 or over to gamble. Always check the full terms of any bonus before opting in.
