Detailed Analysis of the Top Online Slots UK Sites
Our team provides a test-based analysis of the top UK slot sites for your personal preferences. We first highlight our top 3 picks, then review the best slot sites for every style of play. Our CEO, Ionut Catalin Marin has applied his +7 years of experience in the UK online casino industry to create a list of slot sites catering to new and seasoned players.
#1: Casushi Casino – Best online slots UK site for 2023
Our experts picked Casushi Casino as the best UK slot site for 2023 thanks to its vast collection of slot games from top providers, great mobile experience, and user-friendly interface. With over 750 slots on offer from leading developers like NetEnt, Microgaming, and Red Tiger, Casushi brings together a great slots lineup, spanning all themes and features.
You will be able to find multiple titles from the Mega Moolah series, which is a progressive jackpot network, with high pools of over £5000000. Moreover, the website holds around 50 megaways titles, which have higher numbers of paylines. You will be unable to find any bonus buy slots, due to the new UKGC regulations.
- 750+ games from major software developers, like Microgaming
- Intuitive mobile optimization for flawless slot play
- Classic titles alongside new video slots, megaways, and jackpots
- Withdrawal times are slower than some sites
- Few progressive jackpot options
#2: Bally Casino – Runner-Up UK Slot Site
As runner-up for best UK slot site, Bally Casino impresses with its collection of 430+ games from renowned providers like Pragmatic Play and NetEnt. Slot variety spans themes and features, from the latest video slots to classic three-reel games. While the number of titles may seem quite low, the collection is quite diverse, and the slots offer high-quality play. Our experts liked the library of slots at Bally Casino despite the smaller number, however, this is why the site falls short of first place.
If you are a mobile player, you can rest assured. With great mobile optimization implemented by the site, you will be able to enjoy all your favorite titles on the go. Bally Casino also carries the rare progressive jackpots, as well as Slingo titles, which are a combination between slots and bingo.
- Leading software providers, like Pragmatic, Gamesys, and NetEnt
- Optimized gaming on all mobile devices
- Jackpots, Slingo, classic and video slots available
- Smaller game selection than some sites
- No phone support available for users in need of help
#3: Luck.com – Top New Slot Site
As the top new slot site that was established in 2023, Luck.com delivers a thoughtfully curated collection of about 50 diverse, high-quality games from Slot Factory. Despite its smaller size, Luck.com focuses on quality over quantity – each immersive title has varied features and gameplay, and, as opposed to other online casinos, you will never see two similar games in terms of themes.
It is also possible that the slot collection will expand in the future, as Luck.com is a new site. While we were overall pleased with Luck.com’s game collection, we recognize that some of our readers may prefer having the popular slot games they are familiar with available. For this reason, we recommend you use Rhino.bet Casino’s spins welcome bonus and become accustomed to this site.
- Unique slots with diverse designs and features
- Optimized experience across mobile platforms
- Megaways titles are available for players
- Less than 100 titles currently
- There are no jackpot variants available yet
#4: Monopoly Casino – Best for Number of Slots
Boasting an impressive library of over 1300 games, Monopoly Casino shines as the top choice for slot number. In addition to sheer amount of slots, we were also pleased with the fact that the collection offers depth. You get to experience the most popular slot titles from leading providers like Pragmatic Play, NetEnt, and Microgaming. As a first time depositor, you will get 30 wager-free spins that you may use to check out in-house slot titles from the Monopoly series.
The site ensured all players get to experience smooth mobile play on browser, as well as reliable customer service to enhance gameplay across the vast selection for newcomers and veterans alike. However, you may want to check other casinos if you like classic slots, as there are very few 3-reel options.
- Massive 1300+ game library from top providers
- Great optimization for mobile slots play
- No wagering welcome bonus available on the Monopoly slot series
- Selection can feel overwhelming for some
- The number of classic slots is quite limited
#5: Betfred Casino – Best for NetEnt Slots
Betfred Casino emerges as the top casino site for NetEnt slot enthusiasts, with hundreds of titles from the renowned developer. You will find all the British-favourite NetEnt games, including the Starburst series, as well as Gonzo’s Quest. Alongside NetEnt hits, Betfred also delivers a solid mix of nearly 1000 games from other quality studios. However, NetEnt seems to offer the most extensive selection.
This, paired with smooth mobile play, and a welcome bonus consisting of a whopping 200 spins round out the NetEnt-focused experience. The bonus is one of the largest we’ve seen on the UK market, allowing you to try out the most popular slots from the provider for just a tenner.
- Extensive NetEnt selection
- Great optimization for mobile play
- Great welcome bonus with up to 200 spins
- Selection beyond NetEnt is quite bland
- Site design feels dated to some users
#6: MadSlots – Best for Pragmatic Slots
Our experts voted MadSlots the best choice for Pragmatic Play slot enthusiasts, offering one of the largest selections of titles from the acclaimed developer. You’ll find all of Pragmatic’s most popular UK hits like Sweet Bonanza and Wolf Gold on this webiste. Beyond the sizable Pragmatic lineup, MadSlots also provides hundreds of additional high-quality slots from other providers, though their collections are not as diverse.
The one downside is the current lack of jackpot slots. But we want to highlight that MadSlots is a new online casino, and there is high chance jackpots will be added in the future. If you are unsure whether the casino is a great choice for you, you can check out the 100 no deposit free spins at MadSlots, which you can use to make up your mind.
- Wide range of Pragmatic Play slots
- Overall, a high number of 1000 titles
- Great site optimization for mobile play
- No jackpot titles are yet available
- No phone support available
#7: MrQ – Best for Microgaming Slots
We consider that MrQ Casino is one of the best sites for Microgaming, with one of the largest selections of titles from the software provider. Within this game collection consisting of 800 titles, you will also find Microgaming hits like Immortal Romance and Thunderstruck II. Another area we liked at this casino is the expansive 90+ jackpot selection.
However, the customer support at MrQ is where we had to draw some points. There is no phone support available, which we typically recommend for urgent matters. Moreover, the live chat support is not available around the clock.
- 800 slots in the collection, including Microgaming titles
- Solid additional selection from other providers
- 90+ jackpot options are available
- Site navigation can feel unintuitive
- Customer support is not available 24/7
#8: Rainbow Riches Casino – Best for Slot Types
Rainbow Riches Casino excels in offering an immense variety of slot types and features. With over 1000 games from leading studios, the library spans modern Megaways, classic 3-reel, high volatility, jackpot slots, and everything between. We also liked the fact that there are 15 in-house slots, which you will be unable to find anywhere else.
While the collection is large and diverse, the number of jackpots could be improved. We would like to see more titles in this section, especially given the variety in terms of slot types.
- 1000+ titles covering most slot types
- Exclusive in-house titles are available as well
- Both Android and iOS apps can be downloaded
- Smaller number of jackpots
- Limited payment options in the cashier
#9: Buzz Bingo – Best for Progressive Jackpots
With a whopping 100+ progressive jackpot slots, Buzz Bingo is our experts’ top pick for pooled jackpots. Beyond this, Buzz Bingo also provides over 1500 more slots with excellent variety, among which you can try out Big Bass Splash, Fluffy Favourites, and Rainbow Riches.
Besides the great slot collection, you can enjoy a great banking policy too. The minimum deposit and withdrawal amounts are very low, at £5, catering to players of smaller budgets as well. If you want to try out similar £5 minimum deposit casinos, our experts already reviewed them and highlighted the best ones on the UK market.
- 100+ progressive jackpot titles from top studios
- 1500+ additional slots for variety
- Low £5 minimum deposit and withdrawal amounts
- No mobile apps for additional convenience
- Restrictive max cashout limit on bonuses
#10: Play Sunny Casino – Best for Classic Slots
Play Sunny emerges as the premier destination for fans of classic slots, with over 30 three-reel titles alongside its modern selection. Across over 1400 total games, Play Sunny brings a good amount of fruit and 7s slot games, which we appreciated. If you want to go from the classics to the other titles, know that you will find anything you’d like: video slots, megaways, as well as progressive jackpots.
The site is optimized for mobile play, but does not offer any apps that you can download on either Android or iOS.
- 20+ beloved classic physical-reel slots
- 1400+ additional modern games
- Mega Moolah titles are available
- Dated web design lacks visual appeal
- Slow payout processing speed of 2 days

How We Select the Top Slots Sites UK
Each UK slot site in the table easily met our review criteria for safe gaming. Apart from testing individual games, we examined other criteria contributing to the gaming experience, such as game providers, payout rate, game features, responsible gaming instruments, and mobile usability.
How We Review the Best Real Money Slots Sites UK
Slots Casino Real Money Sites’ Security
We considered several variables to determine a slot site’s security other than licensing. For instance, a factor as simple as popularity and reputation can signify reliability.
If an operator has high and positive ratings across several reliable online review platforms and forums, you can take it as an indicator of trustworthiness.
Essential Third-party Game Testing Certificates
Many of our recommended UK slot sites have independent third-party organisations test and evaluate their gaming software to ensure its fairness and functionality. To ensure the gaming quality is tested, we seek approval from eCOGRA, iTech Labs, Gaming Laboratories International (GLI), and similar testing labs.
Slots Variety and Software Provider Trustiness
A wide range of slot games can make it harder to pick a single game but gives you more range and allows you to find a game tailored to your gaming style. We promote only UK slot sites that provide licensed content from industry-leading software providers with a proven track record.
We Test Online Slots Real Money Bonuses Ourselves
- We examine the casino bonus offers and their wagering requirements
- We sign up and claim the bonus with a qualifying deposit or code
- We start wagering on qualifying games
- Once all bonus terms are met, we submit a request for a withdrawal
- Provide withdrawal verification documents (if necessary)
- Wait for the casino to approve the withdrawal and credit the bonus/winnings
We Manually Check Payment Methods
Alongside reviewing the availability of payment methods, we check the efficacy of each payment option. A few of the banking criteria include deposit and withdrawal limits, processing of transactions, and whether the casino or payment service charges any fees. At the very least, a casino should have the following payment methods available to all UK players:
- Skrill or Neteller
- Pay by Phone
- Bank Transfer
Keeping up to Date With the Latest Mobile Gambling Trends
We tasted several slot games in each of the three casinos using an iPhone 14 Pro Max and a Samsung s22, and the games worked exceptionally well, with no lags, crashes, or similar issues, on both devices. Of course, you can even have an older smartphone model and still enjoy optimal game performance.
Our experience has shown that most online casino players in the UK and beyond tend to play on mobile casinos. You should seek the newest mobile casino platforms if you want to play new mobile slots on their release date.
A mobile app is not necessary, but it may appeal to many mobile players.
At the very least, we ensure the slot site is compatible for use on mobile in-browser on all major operating systems: iOS, Windows, and Android. We recommend it only after manually testing a casino’s mobile functionality relating to gaming content, payments, support, security, and user experience.
Online Casino Slots: Sign-up and Bonuses Guide
Below we provide a short player guide on how to navigate between UK slots sites, find the best bonus for your specific slot preferences, sign-up and claim it.
How to choose your best online slots sites to play
- Choose a licensed operator
- Pick a casino with proper game filters
- Pick sites with high RTP slots
- Look for medium-to-high volatility slots
- Find a casino with slots from leading providers
- Check for slot-specific promotions, like free spins
- It’s preferable for the slots to have demo (fun) mode
How to compare online casino slots bonuses
- Look for UK Slots Sites for No Deposit Free Spins: Use our filter to select sign-up slot bonus rounds with favourable terms. Note, easy as the bonus terms may seem, you still have a limited amount of time (around 7 days, on average) to satisfy the remainder of the terms before the bonus expires.
- Find Online Real Money Slots Sites with a Free Sign-up Bonus: A casino can award you with a slots no deposit bonus for your active play, if you are a VIP member, or immediately after you create an account. The former case is to be found in any of UK’s casinos with VIP and loyalty programs. You’ll notice each of the no deposit bonuses above are cash bonuses (as opposed to free spins). But specified slot games qualify for each bonus, meaning you can play first-rate slot games and take advantage of the games’ features while redeeming your bonus at the same time.
- Choose UK Slot Sites With a Valuable Welcome Bonus: By value we mean welcome bonuses with fair terms and wagering requirements and acceptable withdrawal and betting limits. Each of the listed sign-up promos meets our criteria. For some offers, like the Barz Casino welcome bonus, the wager terms may seem slightly above average, though the bonus compensates with other favourable conditions.
- Best Source of Online Slots No Wagering Bonuses: For a small deposit of just £10, you can claim a no-wager free spins bonus at many of our listed casino operators, but PlayOJO is renowned for being a no wagering casino all-around.
Regardless of the no-wager benefit, you still need to read the terms for each bonus to know which games qualify and satisfy the remaining conditions.
Should you play with online slots real money free spins?
With free spins for online slots, real money games can become a much better experience, because you have the opportunity to test the online real money slots sites yourself before depositing.
If you choose from our selection of slots no deposit bonus offers, you are ensured to play on secure slot sites with free bonuses on sign-up and explore various slot games by top providers.
Despite an offer can theoretically result in a real money payout, the fact that it doesn’t require a deposit generates a low expectation due to the equally low value of the spins bonus itself. Still, a no wagering bonus for slots gives you a high chance of generating an early positive bankroll.
How to sign-up at online casino slot websites
- Read our review and carefully choose your slots site
- Prioritize independent slots online casinos for unique bonuses
- Create a new account
- Go through KYC (Know Your Customer) procedure
- Verify your account
- See if you need a deposit to qualify for any bonus
- See which slot games qualify
- Examine game weighting (if there are no wager requirements, there’s no need for game weighting)
- Choose a no-deposit bonus and start playing
Why should you prioritize independent sites? Because with sister sites, there’s a chance you may get excluded from slot bonuses if you claim the same promotion twice or more across the network.
How to claim no deposit bonuses for online slots real money
- Open the casino website and sign up
- Verify financial and personal information
- Agree to casino’s house terms
- Go to the promotions page and claim no deposit bonus
- Complete wager terms on free no deposit slots and other qualifying games
- Don’t go above maximum betting limit
- Don’t request a withdrawal until the completion of the terms
- Cashout winnings after satisfying terms with applicable withdrawal method
What is the best time to play online slots at UK sites?
There is no best time to play online real money slots because all games are governed by a Random Number Generator and pay out randomly. That being said, there is no way to uncover when a slot machine will pay other than hacking into the casino providers’ servers and manipulating something there.
The only way to improve your chances in slots is to play responsibly on safe, best-rated slot sites verified by KingCasinoBonus!

Book of Dead – best high-volatility slot
Book of Dead is our expert’s choice for the best high-volatility slot. Since UK players mainly seek this type of game, we selected Book of Dead, developed by Play’n GO, because it is packed with special features playing.
|Book of Dead Slot Details||Data|
|Slot Type||Video Slot|
|Max Win||250,000x stake|
- Expanding Symbol – Land a special symbol that expands across the reels.
- Free Spins – Landing 3 book scatter symbols awards 10 free spins with expanded special symbols.
- Gamble – Double your winnings up to 5x by guessing the correct card color.
With exotic Egyptian graphics, adrenaline-pumping gameplay, and huge payout potential, Book of Dead delivers an electrifying high-variance experience. You can retrigger the bonus round, which makes this a must-play high volatility slot.
If you’re a frequent Book of Dead player, we recommend taking advantage of slot bonuses with free spins on Book of Dead, like the one from 21 Casino giving 21 free spins on this game. This lets you experience all the bonus features with an average wagering requirement of 35x.
Starburst – best low-volatility slot
Starburst comes second in our top slots ranking, but it’s undoubtedly the best low-variance online slot game in the UK. Free sign-up bonuses on NetEnt’s slot make it a true classic.
|Book of Dead Slot Details||Data|
|Slot Type||Video Slot|
|Max Win||50,000x stake|
- Wild Symbol – The Starburst wild symbol appears on reels 2, 3 and 4 and expands to cover the entire reel.
- Re-Spins – Landing a wild symbol triggers up to 3 re-spins with sticky wilds in place.
- Bet Lines – With 10 fixed paylines, Starburst offers flexible betting options to suit all budgets.
With its cosmic theme, cascading reels and exciting re-spin feature, Starburst has cemented itself as one of the most popular low-volatility slots of all time. The vibrant graphics and synth soundtrack create an immersive, futuristic atmosphere. Frequent payouts make Starburst the perfect low-risk slot for both new and experienced players.
When it comes to Starburst free spins bonuses, our expert recommends thoroughly-tested options that don’t require a deposit, like the Starburst bonus at Space Wins. However, for the best playing experience and an easier time cashing out winnings, we recommend a lower wagering requirement than the 65x wager at Space Wins. We believe PlanetSportBet’s bonus with a deposit of £20 is worth claiming for its low 10x wagering.
Mega Moolah – best progressive jackpot slot
We chose Mega Moolah as the best progressive jackpot slot due to its popularity in the UK and beyond. Mega Moolah is a slot with multiple variations like Mega Money Wheel connected in the same network. All the games feature 5 reels, 25 paylines and the progressive jackpot slot fueled by Microgaming/Games Global.
|Mega Moolah Slot Details||Data|

- Wild Substitutions – The lion symbol acts as a Wild and substitutes for all symbols except scatters.
