The best slots sites that offer real money slot games in the UK
The United Kingdom is probably the largest and most advanced of all iGaming markets, and casino gaming has been almost equally popular as sports betting.
However, choosing one in a list of hundreds of casino sites, all with endless choices of slots, can sometimes prove overwhelming. We lend a helping hand by narrowing down that list so you won’t go wrong no matter your final choice.
First Look:
Overall Best Site - Mansion Casino
High RTP Slots Games - Grosvenor Casinos
Best Selection of Slots - The Sun Vegas
Best for Free Spins - Mr. Spin
One of the Fairest UK Sites - PlayOJO Casino

How we find the top UK slots sites
Security and licensing - Online gambling and sports betting in the UK is regulated and legal, and any site licensed to operate in the space is overseen by the United Kingdom Gambling Commission (UKGC). If an online casino doesn't have the UKGC's seal of approval, we urge you to proceed with caution.
Game variety - When it comes to playing slots, we recommend casinos with different game types. At our recommended casinos, you’ll be able to find everything from classic 3-reel slots, 5-reel slots, 6-reel slots, jackpot slots, or Megaways.
Bonuses and promotions - Most casino sites, not just those in the UK - often have one or several perks explicitly designed for slot gaming. Free spins and bonus money are the two main types of promotions found at pretty much all casino sites.
Mobile gaming - Land-based casinos can only fit so many slot machines. However, with online casinos, you get access to thousands upon thousands of games - all available for instant play on desktop and especially on mobile. As such, we were careful to select sites where mobile gaming is up to a satisfactory standard.
9 best real money slots sites in the UK
1. Mansion Casino – overall best site
Great site for slots overall
Excellent welcome bonus
Established reputation
Proper mobile platform
Enormous jackpots
Mansion Casino, a subsidiary of the Mansion Group, is among the most distinguished casinos and sportsbooks globally, with nearly two decades’ experience in the business. So, when it comes to all forms of casino gambling, particularly slots, Mansion could be your bag.
Besides its extensive menu of slot games, Mansion Casino runs an immersive, true-to-life live casino section that’ll sate the needs of both inexperienced and seasoned players.
Their welcome promotions include packages tailor-made for both high rollers and the more economical slots players. Mansion stands out as a leading casino site in several ways, but one quality that deserves referencing is the total amount of their slots jackpot.
The slot jackpots can be worth from tens to hundreds of thousands of dollars. But, as with all games of chance, you’d need a special relationship with Lady Luck to hit one of the significant slot jackpots.
One downside about the slots at Mansion is that, unlike at some other sites, you must have an account to play for free.
2. Grosvenor Casinos – high RTP slots games
High RTP-percentage slots
Unmatched prizes and giveaways
First-class slot casino all-round
Founded in the late 1960s, Grosvenor is one of the oldest casino chains in the United Kingdom that also operates a high-class digital casino, especially suited for slot punters.
Grosvenor is also one of the most tightly secured sites on our list. The leading agency in the UK tasked with ensuring casino and sports sites comply with the latest laws and adhere to existing regulations is the United Kingdom Gambling Commission (UKGC). However, Grosvenor is licensed both by the UKGC and the Alderney Gambling Control Commission.
Concerning their slots, they have an excellent choice of jackpot slots that include daily jackpots and multi-million Mega Jackpot slots such as Wheel of Fortune, Golden Goddess, and Cleopatra. And the best part? They’re playable in demo mode even before you sign up.
Their games’ RTP is typically above 90%. For instance, Magic of the Nile, with an RTP of 96.02%, is a must-try if you’re into slots.
3. The Sun Vegas – best selection of slots
Wide selection of slot machines
Special in house slots
Highly credible operator
The Sun is one of the best-known British tabloids with a circulation of more than 1.2 million. But who knew they’d also provide one of the best platforms for slot gaming? They even create their own slot machines, such as The Sun Megaways.
Besides famous and classic slots, at The Sun Vegas, you can find the latest games alongside more obscure titles that players often sideline despite being equally as engaging as notable titles like Starburst and Book of Dead.
The Sun Vegas is the casino arguably with the best choice of jackpot slots. There are dozens of pokies that you can play to increase your chances of winning any of the several jackpots. These games include Age of Gods: God of Storms, Reel King Mega, Blue Wizard, Heartburst, and many more.
Like Mansion, however, The Sun Vegas also requires you to register first before you can try any slot in demo mode.
4. Mr. Spin – best for free spins
Thousands of free spins to be won
Well over 55 jackpot slots
Frequent no deposit free spins
Mr. Spin has a catchy name for players bent on locating the perfect slots site. And choosing this site will be one of the best gambling-related decisions they will likely make.
Mr. Spin has more jackpot slots than any site we’ve analyzed for this review, except one or two. All in all, there are 60 jackpot slots with a fixed jackpot of over £200K.
One marked quality of this site is the number of free spins it doles out this summer to encourage slot gaming. For instance, the Golden Summer promotion has a prize pool of tens of thousands of free spins, of which you can earn a portion if you participate in the tournament.
They also offer a welcome no deposit bonus that allows you to play for free on certain slot games.
But despite having many jackpot slots, the overall number of slot games is considerably limited compared to Mansion or Slots Heaven, for example. There is still a decent choice of slot games, with various themes, paylines, and bonus features, only it’s not as great as other casino operators.
5. PlayOJO Casino – one of the fairest UK sites
Give bonus free spins
Great for casual slots play
Fair terms and conditions
Transparent rules
Wagering (or play-through) requirements often take the fun out of any bonus given the stratospheric amounts you must spend playing slots, which are one of the only games that count 100% toward reducing the wagering requirements.
PlayOJO changes that by having neither wagering requirements for most of their offers, limits to the maximum amount you can win with free spins, nor restrictions to how much money you can withdraw from your account.
That essentially means if you claim their free spins offer, you won’t have to play through your potential slots winnings a specific number of times, unlike at pretty much every online slots site ever.
This policy virtually makes PlayOJO Casino one of the most user-friendly sites for slots in our review. Some of the most popular slot titles at PlayOJO include Zeus: Ancient Fortunes, Book of Adventure, Starburst, Gonzo’s Quest Megaways, and more.
We particularly like their slots because they include detailed information such as how many players played a particular title and the biggest win on that slot. For instance, at this time of writing, Thor: The Trials of Asgard, one of the site’s most popular slots, was played 486 times in the past 6 hours, and the biggest win was more than £17,000.
6. Magic Red – best for slaying slots on the go
Suited for mobile slot punters
Dozens of new slot games
Quick registration
Simple page layout
In 2014, the iGaming world welcomed Magic Red Casino - a casino under the Aspire Global platform - purposefully designed to accommodate mobile slot gaming on the move without gamesters having to browse to find a specific slot or payment method endlessly.
One reason it’s suitable for playing various high-RTP slots on the go is the quick registration and even quicker login processes.
Other characteristics of Magic Red worth mentioning are the rock-solid welcome bonus that’ll extend your play and its level of security. Magic Red works with cutting-edge technology and employs an encrypted SSL protocol to guarantee no weak spots that could be abused by fraudsters, hackers, viruses, and other threats.
The company holds two licenses issued by the Malta Gaming Authority and the UKGC.
Buffalo King Megaways, Joker’s Luck, Wolf Riches, and Tomb of Dead are just a few of the hundreds of slots on their menu.
One of the drawbacks here is the slow loading time, which some players could find frustrating.
7. Genesis Casino – best casino providers
Features slots from top developers
Wide choice of payments
Highly regulated
Genesis Casino was introduced in 2018 with licenses from both the UKGC and the Malta Gaming Authority to ensure adherence to current gambling regulations and policies. As such, Genesis is one of the safest places to play slots and other casino games in the United Kingdom.
And boy, do they have some slot choices for you!
The slots, as well as most other games, are supplied by more than a dozen casino software developers.
And these aren’t just your run-of-the-mill companies, but industry leaders such as Quickspin, Evolution Gaming, Pragmatic Play, NetEnt, Microgaming, Play’n GO, Red Tiger Gaming, etc. It’s like a roll-call of the most outstanding providers to ever grace the iGaming scene!
You can play top-rated slots like Starburst, Fire Joker, Sweet Bonanza, Immortal Romance, Money Train, and hundreds more for free.
One downside is there are no filters to find a game based on a provider or wager limit, which forces players to spend a considerable amount of time checking games individually before they find what they like.
8. Slots Heaven – best mobile app
Excellent mobile app
Highly secure and licensed by UKGC
Suitable slots bonus
Slots number in the hundreds at Slots Heaven - all developed by major online casino software developers such as Playtech, the Skywind Group, and Eyecon Ltd. All of them are renowned providers - tightly regulated and licensed by the UKGC.
Slots Heaven itself is licensed by the UKGC, as well as by the Gibraltar Betting and Gaming Association.
Mobile gaming is a delightful experience at Slots Heaven, and their in-house application gives you access to over 300 slots. These include games with big jackpot prizes, including that of Playtech’s 5-reel Leprechaun’s Luck.
They have a pretty average welcome offer; however, the free spins you can use on their super-popular Age of the Gods make the offer more exciting.
Slots Heaven is undoubtedly above average when it comes to the quality of slots. However, they somewhat disappoint concerning the selection, as they appear to have a little over 350 slot titles. That number is dwarfed when put side by side with the thousands of slot games found at some other online casinos.
9. Masked Singer Casino – most games
Over 3,000 games
Top mobile gaming application
Exciting tournaments
Big jackpot prizes
With just under 3,400 games in total, Masked Singer has one of the most extensive and colourful slots galleries. Slots make up the bulk of the games at Masked Singer, and there are all the usual games from established developers.
Masked Singer is always up to date with the latest releases and does not miss a chance to include new games from the biggest game providers as they come out.
Masked Singer is particularly suitable for slots because they allow users to find games that best suit them based on their provider, minimum/maximum bet, volatility level, and the number of pay lines, among other filters.
Although not all slots are available in demo mode, Masked Singer is possibly the best slot site on our list simply because it allows you to select a game specifically tailored to your needs. For instance, if you seek a medium-volatility, adventure-themed game by Elk Studios, you can play Taco Brothers, Hong Kong Tower, or Wild Seas.
Strange as it may seem, as far as slot gaming is concerned, Masked Singer may just be the most easy-to-navigate casino.
