Which are the Top 5 Microgaming Casinos in the UK Right Now?
Microgaming is one of the leading suppliers of software to the iGaming market. Casino sites seek the prestige and credibility that comes with hosting Microgaming titles, so there are hundreds of sites in the UK that could be considered Microgaming casinos. Our job is to filter through this group of online casinos in search of the real gems. Our experts applied our testing framework to more than 30 different sites and have delivered their final verdict – all you need to do is compare the standout features of these sites and pick the one you like best.
| Rank | Casino Name | Welcome Bonus | Casino Game Count | Min Deposit | Expert Rating |
|---|---|---|---|---|---|
| 1 | Betfair Casino | Get 50 Free Spins When You Sign Up – Then Bet £10 and Get 100 More | 1,000+ | £5 | 5/5 |

| 5 | Duelz Casino | Deposit £25, Get 140 Free Spins | 2,000+ | £10 | 4.7/5 |
Betfair Casino
Betfair is the only Microgaming casino in our top list that offers a no deposit bonus to all new customers who sign up with the promo code CASF51. You’ll receive 50 free spins at this casino immediately after you sign up; these can be used on Crabbin’ For Cash and come with no wagering requirements. It’s rare to find no deposit, no wagering bonuses at online casinos, so we couldn’t ignore Betfair for our top spot. There’s also no mention of max winning caps, which further enhances the value of this outstanding offer.
If you enjoy the no deposit bonus experience, this is only the first half of the welcome bonus. You can then make your first deposit of £10 and receive another 100 wager-free spins to use on one of six Jackpot King games: Crabbin’ For Cash Extra Big Catch, 7s Deluxe Fire Wheel, Eye of Horus, Fishin’ Frenzy, The Goonies and Betfair Even Bigger Bananas. Players have seven days to use their free spins before they expire.
Of course, there’s also a great range of Microgaming slots at this casino, including Mega Moolah, Thunderstruck II and Gold Blitz. We had a spin of the latter during our testing, enjoying the game’s electrifying graphics and the potential to win three different jackpot prizes.
Offer is available to new customers who register via the promo code CASAFS. Winnings are paid in cash. Free spins valued at 10p. Get an additional 100 free spins when you deposit and spend £10 on eligible games. Full T&Cs apply.
William Hill Casino
Many players may prefer William Hill’s casino welcome offer, which doesn’t mess around with no deposit bonuses, and instead offers 200 free spins to all new players who stake £10 first. You’ll need to use the promo code BBS200 when you sign up in order to receive the spins, which come with no wagering requirements and a 72-hour time limit. Unfortunately there’s a max winning cap of £30, so you won’t break the bank with this offer.
The William Hill games library contains over 2,000 titles, with plenty of focus on Microgaming releases. This includes the legendary Immortal Romance series, with six different titles under this iconic Microgaming banner: four slots, one instant win game, and Immortal Romance Roulette. The original Immortal Romance slot is a high-volatility game with great bonus features, a 96.68% return-to-player (RTP), and a max win of 12,750x the stake. It remains one of the standout releases on the Microgaming slots list, despite being released 15 years ago.
#AD 18+. Play Safe. Ends 31/12/26. New UK customers only. Register with code WHV200, opt in via promo page and within 7 days deposit £10+ & stake £10+ from main balance on the advertised game to receive 200 Free Spins (10p each). Free Spins expire 72 hours from credit. Free Spins winnings must be wagered 10x on the advertised game within the same period. Winnings capped at £30. 1 per person. T&Cs apply. gambleaware.org
Betfred Casino
The Betfred Casino welcome offer is identical to William Hill: spend your first £10 in the Games or Vegas sections of the site and receive 200 free spins as a reward. The free spins can be used on any of the following slots: Betfred 777 Jackpot King, Cash Strike Hotstepper, Eye Of Horus, Fishin’ Frenzy and King Kong Cash Even Bigger Bananas Jackpot King.
The free spins come with no wagering requirements, so whatever you win can be immediately withdrawn as cash. You’ll need to use the promo code SPINS when you make your first deposit in order to be eligible to receive the free spins, and you’ll need to do so within 14 days of opening your account. Once the spins have been credited, players have seven days to use them before they expire. One of the best things about this Microgaming casino is that it regularly dishes out no deposit free spins bonuses for existing customers, with five, ten or even 15 spins commonly up for grabs, completely for free.
Among many others, the Betfred Casino selection of Microgaming titles includes the Irish-themed 9 Pots of Gold, which our reviewers tested out during the review. This colourful slot provides plenty of free spins opportunities, with up to 30 available on every spin. It comes with an RTP of 96.24% and a slightly higher than average minimum stake of 20p.
BetMGM Casino
200 free spins can also be yours when you sign up to BetMGM Casino – all you need to do is sign up and spend an initial £10 deposit on casino games within seven days of opening your new account. Free spins can only be used on the Pragmatic Play slot Big Bass Splash and will expire three days after they’ve been credited.
BetMGM is one of the classiest operators around, with a mobile app befitting of an operator heralding from Vegas. The mobile app experience is clean, quick, and elegant, with smooth interfaces sweeping you across the casino’s full range. We’re particularly impressed with the Microgaming live casino section, which covers a range of tables across blackjack, roulette and baccarat variants, as well as other experiences.
This Microgaming casino pays particular attention to the Mega Moolah franchise. Not only is the original mega jackpot slot available, but players can also spin the reels of Mega Moolah Goddess and Mega Moolah Megaways, and spin the wheel of Roulette Mega Moolah. Fancy an adventure? Fire up Lara Croft Temples and Tombs just like our reviewers did and spin your way to ancient treasures.
#AD 18+ New cust only. Opt-in required. Time to deposit/wager 7 days. Deposit £10 & wager 1x on casino games (wagering contributions vary) for 200 Free Spins worth 10p each on Big Bass Splash. 3 day reward expiry. T&Cs apply.
Duelz Casino
Duelz is a casino unlike any other in this list. As well as hosting over 2,000 casino games, players at this site are invited to also compete with one another through magical duels. You can collect XP and SP, pick up treasure chests, and cast spells to defeat opponents in one-to-one combat. It’s an exhilarating approach to loyalty points that delivers an entirely new dynamic to the online casino experience.
From the perspective of Microgaming, Duelz also excels. Jackpot slots such as The Finer Reels of Life present the chance to win big, and there’s also plenty of attention given to the Mega Moolah franchise, with 16 different titles under this banner included in the collection. The rest of the catalogue is filled out with classics such as Immortal Romance, Thunderstruck II and Gold Blitz. Our reviewers had a spin on Microgaming’s 9 Pots of Gold, which can also be played in a live dealer format.
Duelz Casino promises 140 free spins to those who make a minimum first deposit of £25. The spins are delivered in batches of 20 per day for the first seven days, with each batch eligible to use on a different game. You must log in and accept each batch of spins every day; if you don’t they will be lost. There’s a winning cap of £100 per day and wagering requirements of 10x attached to any winnings.
#AD 18+. New players. Min deposit £25. Up to 140 Free Spins (20/day for 7 consecutive days on selected games). Manually claimed daily or expire at midnight with no rollover. Free spin value £0.10. Max winnings £100/day as bonus funds with 10x wagering requirement to be completed within 7 days. Game restrictions apply. Play Responsibly! www.gambleaware.org | Full T&Cs apply.
Pros and Cons of Microgaming Software
There’s no doubt that Microgaming remains one of the most respected names in iGaming development, despite the emergence of dozens of high-quality studios since the company’s launch. Its experience, variety, and depth are among Microgaming’s core strengths, but you may prefer games created by alternative developers. The list of pros and cons below should help you decide if Microgaming titles are right for you.
Pros
- Founded in 1994, with over three decades of iGaming experience.
- Produces games of all types – from classic three-reel slots to innovative live dealer experiences.
- More than 850 different casino games in its collection.
- Smooth gameplay and fast loading times on Microgaming’s Quickfire platform.
- Owns a range of smaller games studios, bringing greater variety and different styles to its releases.
Cons
- Since Microgaming launched in 1994, some of its older games can feel dated.
- Has faced accusations of “cloning” its successful slots templates across different releases.
- Not many high RTP slot games.
Top Microgaming Games: RTP and Volatility Analysis
With a library of more than 850 casino games to choose from, it’s not easy to reduce the Microgaming catalogue to just three games, but we’ve given it a go. The following three titles are widely considered to be among Microgaming’s greatest ever creations; all of them have generated various spin-offs, which indicates their enduring success.
| Game Title | Game Type | RTP % | Volatility | Unique Mechanic |
|---|---|---|---|---|
| Mega Moolah | Progressive Jackpot | 88.12% | High | Massive jackpot potential |
| Immortal Romance | 5-reel | 96.86% | Medium | Cascading reels |
| Thunderstruck II | 5-reel | 96.65% | Medium | N/A |
Mega Moolah
Mega Moolah’s low RTP of 88.12% indicates who this game is best suited to. For higher rollers who can manage long periods of no wins, Mega Moolah is a must try. This is known as a progressive jackpot slot, with potential payouts fed by players wagering on the game from all around the world. This mechanic generates eye-watering sums: the record payout of this slot is a staggering £13m+.
Immortal Romance
The vampire-themed Immortal Romance became an instant cult classic thanks to its high-quality graphics and numerous bonus rounds. Wilds, scatters, free spins and multipliers are all in play here, and there’s also a bonus game with cascading reels. Immortal Romance is a medium-volatility slot with a higher than average RTP of 96.86%. This makes it a great all-rounder, suitable for players on a range of budgets.
Thunderstruck II
Thunderstruck II shares many similarities with Immortal Romance, including wilds, scatters, multipliers, free spins, and its own bonus game. This game, however, takes its inspiration from Norse mythology, with gameplay adorned with symbols of Viking gods. Similarly to Immortal Romance, this medium-volatility slot is suitable to all players, although players may note a slightly lower RTP of 96.65% here.
Mobile Experience and Technical Performance
Microgaming claims to be the first online casino software provider to specifically design and develop games for the mobile market. The company prides itself on its ability to cater to mobile-first players, and all of its games are developed using HTML5 technology. This enables a dual release approach, where new game releases are instantly made available in both desktop and mobile formats. Mobile Microgaming players enjoy fast loading times and interfaces that instantly adapt to smaller screens, creating a first-class mobile casino experience.
How Did We Test and Rank the Best Microgaming Casinos?
There are hundreds of Microgaming casinos out there, so how do we shortlist the cream of the crop? Our reviewing process covers many areas; in search of the best Microgaming casinos, we specifically focused on the following five key areas:
- Software Integration — We run tests on several Microgaming games before we recommend a site, ensuring loading times are fast and graphics are smooth.
- Bonus Fairness — We assess the quality of the casino’s welcome bonus to see if it offers a fair and generous introduction to the site. This includes taking a look at the terms and conditions to see how well the casino treats its players.
- Payout Speed — We’ll deposit and spend money at the casino, then withdraw winnings to evaluate the site’s withdrawal process. Top marks for easy, instant withdrawals.
- Mobile Stability — Did the games crash or lag when playing in a mobile format? We answer these questions by testing both iOS and Android platforms.
- Licensing Check — All of our reviews start in the same place, and that’s a check on the casino’s current licensing status. If the site doesn’t have a UKGC licence, our review ends there.
Microgaming vs. The Competition: UK Market Comparison
We’ve been singing Microgaming’s praises throughout the guide, but the iGaming industry is serviced by dozens of other software developers, all of which offer something different. Two of Microgaming’s biggest rivals — NetEnt and Pragmatic Play — also largely dominate the games libraries of UK casino sites.
Whether or not you prefer releases from these studios — or any other software developer for that matter — will depend on your own playing preferences. If you’re looking for the most colourful slot titles, we suggest checking out the NetEnt portfolio; if you’re looking for the latest releases, Pragmatic Play is prolific in bringing new games to market. We compare some of the key features of these three developers in the table below.
| Feature | Microgaming | NetEnt | Pragmatic Play |
|---|---|---|---|
| Core Strength | Over 850 games and over two decades of experience. | Strong focus on the mobile-first gaming market and with two decades of experience. | A fresh and ambitious game portfolio, with as many as eight releases every month. |
| Best Known For | Game variety, progressive jackpots, and branded slots. | Colourful graphics, mobile slots, and innovative bonus features. | Game variety, high volatility slots, and free spin eligibility. |
| Avg. RTP Range | 95-97% | 96-98% | 96-97% |
Despite a competitive and talented field, Microgaming is still one of the most respected and sought-after developers in the industry for both operators and players alike. Its catalogue of more than 850 games is significantly more than most other providers have contributed to the industry, and through its acquisitions of other studios, it continues to churn out innovative and entertaining releases.
Its two decades of experience places it at the very foundations of the online gaming sector and this longevity has endeared Microgaming to many fans over the years. From those first classic three-reel slots to the outlandish potential of progressive jackpots, no developer can claim to match Microgaming’s scope over this period.
Microgaming casinos are also known for their accumulation of the developer’s branded slots. Through exclusive partnerships with major film studios, Microgaming has been able to develop much-loved games based on blockbuster motion pictures and TV shows, including Terminator, Lara Croft, Game of Thrones, Lord of the Rings, Jurassic Park, The Dark Knight, Gladiator, Bridesmaids and more.
Are Microgaming Casinos Safe and UKGC Regulated?
All of the Microgaming casinos recommended on this page are fully regulated by the UKGC and safe to play at. Microgaming itself is also licensed by the UKGC, meaning that its products are regularly tested for their fairness and safety features.
Whether you’re playing at new Microgaming sites or online casino veterans, you must always gamble responsibly. Microgaming software integrates with tools such as deposit limits, spending limits, and time limits, allowing players to set up their own limits according to these three metrics. You can also use reality checks and time outs to keep things fun, light-hearted and entertaining.
If you’re worried about your gambling habits, it’s important to share your concerns as soon as possible. If it’s too difficult to tell someone close to you, remember that there are many problem gambling organisations in the UK that can help. Places like GambleAware and GamCare offer confidential, professional and non-judgemental treatment services and support, so don’t hesitate to get in touch.
