The UK is blessed when it comes to slot sites, offering a huge range of slot titles to choose from. While this is fantastic it can also be overwhelming trying to decipher which are the best slots sites to play at. That’s why it is useful to weigh up the pros and cons of the online slot site while also understanding how our team of experts rates and reviews sites to get a holistic point of view. We take the good and the bad of every slot site in the UK to ensure your online gambling experience is fun and exciting, understanding some of the negatives that may come with certain brands will ensure you pick the best of the best in the UK.

Let’s dive into the key pros, cons, and our own criteria we take into consideration. With this knowledge, you will be able to choose from the best UK slot sites with ease. We’ll also list our editorial picks for those who wish to dive straight into some elite UK sites.

UK Slot Site Pros

  • A safe playing environment -When you take a look at the best slot sites you will see that they are probably the most heavily regulated ones that exist. The UK Gambling Commission (UKGC) is widely regarded as the ultimate governing body when it comes to online casinos. The UKGC goes to great lengths to ensure that casinos are fair and that players are protected.
  • Seemingly unlimited titles to play -Okay, so the number of slot titles in the UK isn’t quite infinite, but it does certainly feel that way. When you visit any of the best UK slot sites, you met with so many titles to choose from. Your biggest problem is often knowing where to start.
  • The best game developers -Slot sites are selective when it comes to who provides their games and software. You’ll only find titles from top providers that are well-known and respected. These include the likes of NetEnt, Playtech, Yggdrasil, and Microgaming. While we are biased towards slots, other casino games such as live dealer games are often available at slot sites in the United Kingdom.
  • The biggest jackpots - We all know that slots are a form of entertainment and that no one should wager more than they can afford to lose (play responsibly). However, that doesn’t mean that there aren’t some amazing jackpots up for grabs. When you look at progressive jackpots on games such as Mega Moolah, the prizes run into millions of pounds!

UK Slot Site Cons

  • Limited to the UK only - Now, obviously, if you’re a UK citizen this isn’t going to be much of an issue. However, there are players based overseas who realise that online slots sites have a great deal to offer, but they’re unable to enjoy them. To enjoy all that UK-based slot sites have to offer, your going to need to live in the UK.
  • No credit card deposits -This can be seen as a pro and a con. The UK banned the use of credit cards at online and land-based casinos. The downside here is that credit cards were a hugely popular payment method and offered levels of protection that debit cards don’t. The upside, however, is that it has stopped people from gambling with money that they don’t have.
  • No bonus buy options -In some countries, you don’t need to unlock bonus rounds when playing slots. You can buy your way to them. In the UK, however, this practice was banned by the UKGC as it felt that it encouraged players to deposit more than they could afford. This is a feature that many still miss.


Now that we have analysed the advantages and disadvantages, it’s time to unleash our expert perspectives. At The Slot Buzz, we don’t just look at the headline welcome bonuses, or the typically constructed casino review, we research and present all the key features that make up the best slots sites in the United Kingdom. Take note of each point carefully as some of these will carry more importance than others. While it’s a personal preference, our dedicated team has wagered at every online slot site in the UK imaginable, so here is what we look out for while ensuring our top lists showcase the cream of the crop!

  • Bonuses and Promotions – Bonuses are one of the most significant differences between land-based and brick-and-mortar slot sites. The vast variety of welcome bonus offers, bonus spins, and bonus money can be overwhelming. That’s why we do the work for you, ensuring you have the most lucrative bonuses at slot sites UK all at the tips of your fingers.
  • Bonus Terms and Conditions – What are the playthrough requirements? Is the bonus redeemable? What are the maximum bets and the maximum wins with a bonus? Are any payment methods excluded from deposit offers? These questions pop up daily among slot players. Visit our dedicated pages to find, or have a read at the bonus terms we have attached to each offer in the above list of welcome bonus offers.
  • Games Catalogue – Imagine the fuss of installing a massive slot machine into a land-based casino. This task is thankfully not necessary for online slots sites releasing a new slot game, and in turn, large volumes are added to catalogues monthly from video slot games to progressive jackpot slots and more. This provides you with wider game availability than ever, from popular slot games to funky new releases. As we are consistently playing online slots, we know only to promote sites with reputable catalogues, games with high RTPs, and slick themes.
  • Slot Site Usability and Games on Mobile – At The Slot Buzz, we enjoy playing the latest online slots no matter where we may be. Whether that is taking a stroll, chilling on the couch, or even in transit. Thanks to mobile slot sites playing online slots on the go are effortless.
  • Cashier – Which payment options are available for deposit and withdrawal and are there any fees? How much can I deposit and withdraw at one time? Can I make the minimum deposit required to claim the 1st deposit offer with any of the payment methods provided? These are vital questions that we dive into at all online casinos. To find out more about payment methods available head over to our banking methods section.
  • Account Verification – We have created accounts for verification at all online casino sites and slot sites to ensure there are no kinks in registration and account verification. Any issues that arise, we contact the gambling venues to assure you have no issues before entering the casino.
  • Progressive Jackpot Wins – It is critical to understand the procedure of withdrawing a big jackpot win. These withdrawal times differ among all the best online slot sites, but not to worry, we detail these cashout times within our reviews. On top of that, we only promote the biggest progressive jackpot slots for all our UK fans.
  • Customer Support – What is the reputation of the slot site for customer services and how accessible are the team through phone and live chat? This is where we test the knowledge and speeds of customer supports services. Assuring your online casino experience is smooth while wagering on the best online slots is our number one priority.
  • Security and Licensing – All online slots sites and online casino sites on offer at The Slot Buzz are fully licensed and regulated by the United Kingdom Gambling Commission. We only facilitate UKGC online casinos to guarantee your safety while playing slots online.
  • Awards, Accreditations & Reputation – This is where our team’s experience in journalism comes into effect.

In fact, their simplicity is one of the reasons that they remain so popular. Let’s consider the basic steps to take for you to play:

This is where you’ll learn all about the symbols in the game. It will show you what each symbol is worth and what each combination will bring you. Unless you study the information here, you’ll pretty much be playing blindly. Take your time and make sure that you understand the game.
Next, you need to decide how much you’re going to wager. You will find that slots come with minimum and maximum stakes. You need to be sure that you’re comfortable with what you decide to go with. A bigger stake could lead to bigger prizes, but equally a losing streak could bring your playing time to an abrupt end.
With your stake set, it’s time to spin and this is when things start to get exciting. You already know the symbols that you need to appear to win and the anticipation builds as the reels start to slow. few casino games, if any, can match the feelings of excitement generated by slots.
Most of all, have fun! Slots are a form of entertainment and with so many variations and themes available in the UK, you can be sure to be entertained for days on end.


Now that you have an understanding of how to play slots online, you’ll need to understand the different variations of slot games available to play. Finding which slot mechanics, type of gameplay, and general interests you have will help you choose similar groups of slots to your liking.


The vast majority of online slots available in the United Kingdom are video slots, they are a modern make-up of classic slots that we were all so used to once upon a time. These game offer from 5 to 50 paylines, with winning combos from left to right. Bonus rounds are frequent and rewarding, themes are vibrant and interactive, and new games are released almost daily. One thing is for sure, you will never tire of playing video slots with the vast portfolios at slot sites on offer.

Best Video Slot – Gonzo’s Quest

Gonzo’s Quest gets everyone’s imagination going since 2011 with its 20-payline journey to discover riches enhanced by an avalanche feature. NetEnt’s first platinum game entertains seasoned and new slot fans alike via exceptional 3D quality and awards a max win of up to 37,500x. In February 2017, NetEnt announces the launch of Gonzo’s Quest video slot in virtual reality. The high volatility search for riches continues at the best slot sites in the UK with the addition of Gonzo’s Quest Megaways™ expanding the number of ways to win by up to 117,649.


Classic slots are the age-old masterpieces that were available on the Vegas casino floors before modern technology took over. They are a stripped-back version of video slots, removing all the bells and whistles so you can just focus directly on the gameplay. While the more modern versions of online slots blow these games out of the water, they still have their place when you need some time to step back and enjoy the simplicity of the reels.

Best Classic Slot – Mega Joker

The most iconic classic slot of all time is Mega Joker, for many online and mobile slot fans it is the perfect game due to its rare high variance gameplay combined with a phenomenally high 99% RTP. Combining jokers, fruity flavours and treasure chests, one of the astonishing features is the supermeter mode. It’s a combo of mystery and nostalgia blended with splendid progressive jackpot payouts that can reach up to £1,648,338!


For those who are lovers of films, TV shows, game shows, and comic books branded slots are a perfect choice. They perfectly depict characters, music, and storylines all the while you are having fun online gambling.

Best Branded Slot – Guns N’ Roses

Guns N’ Roses made history as the biggest online and mobile slot launch ever and continue to become one of the most successful online branded and music-themed slots. A huge fan-pleaser is the ability to pre-select the slot playlist before getting on stage with Slash and Axl Rose. Every bonus feature is worth an encore shout from the crowd-pleaser to the appetite for destruction. Enjoy one of the best rock and roll branded slots of all time and snatch up a prize worth up to 225,000 coins.


Megaways slots were created and introduced by Big Time Gaming back in 2015. The random reel modifier mechanic wasn’t an initial hit among avid video slot players. However, BTG released hit after hit which soon spread like wildfire amongst the industry. Megaways slots create over 117,649 ways to win where the game reels expand to as many as 7 or more rows high. Along with an enormous number of ways to win, many Megaways slots offer a cascading reel feature where the winning symbols are removed to make room for more symbols to fall in. The new symbols that have dropped in and the number of payline changes on the screen.

Best Megaways slot – White Rabbit Megaways™

The best Megaways slot is also one of the finest crafted by the Big Time Gaming in-house developers. It’s the five-reel tale of Alice visiting Wonderland to meet up with Cheshire Cat, Tweedledee and Tweedledum and the Mad Hatter. Described as one of the most superb Megaways slots to deviate from the norm, White Rabbit features up to 248,832 mega win ways and the highly-impressive high volatility slot offers a 97.72% RTP. It’s a fantasy-inspired adventure that leaves no room for entertainment improvement.


Jackpot slots are modern slots with a jackpot max win-up for grabs. They often come in the form of 5-10k in the UK, but if you are looking for something a little more exciting then check out progressive jackpot slots. As the name would suggest, the jackpot is progressive, the more people play the higher the amount gets within the game.

Best jackpot slot – Book of Golden Sands

Pragmatic Play combines a highly entertaining Egyptian theme with an abundance of winning opportunities in the six-reels Book of Golden Sands slot. Available at the best UK slot sites, the 729 ways to win high volatility video slot features wild multipliers, scatters, special expanding symbols, free spins and a 10,000x jackpot!


Free online slot games online or demo modes come in every online slot type mentioned above. As the name would suggest these slots allow you to play completely free. The game provides you with a bankroll and you can choose your stake and play as normal. Of course, the money you win within the game is not there for keeping, but this is a great method of practising, developing strategies, and testing out new games.

Best Free Slot – Planet of the Apes

Planet of the Apes is a unique dual-action branded video slot that brings together two of the most popular films of all time. It is nominated as the best free slot since the movie-themed slot game provides double-up high-paced action, most beneficial to those knowing what to expect. The exciting features line-up include scatters, stacked wild symbols, multiplier, free spins, and the rise bonus. The dual-action takes place across two adjacent reel arenas, both the rise and dawn area features five reels hosting 20 paylines. It’s a video slot unlike any other ensuring an unforgettable blockbuster adventure across 10 reels with 40 paylines.


Slot Site Game Software

As seasoned players will know, once you enjoy an online venue and have got a feel for some games, it’s time to refine your search and test out various game developers. There are tons of different software companies out there, from industry giants like Playtech, Microgaming and NetEnt, to newer studios like Red Tiger Gaming and Thunderkick. Each will have its own graphical styles and game types, with varying volatility, RTPs and maths models across their classic, jackpot, and video slots. Not every casino brand is in partnership with every software supplier so before you make a deposit you should look to see which slots you can play at each site. Some brands sign exclusive deals with one supplier – this is common in the case of Playtech and Microgaming. Others will partner up with multiple suppliers to provide a wide range of games. For our money, the latter is the best slot site to play at, offering the widest choice in their game catalogues.

You can see which suppliers are working with each slot site in our listings. To give you an indication of what each game provider is about, let’s take a brief look at the heavy hitters you will find at the top-rated slot sites in the UK.

Stay within your Bankroll Amount – Keep in mind the amount of money you are willing to wager over the course of your time spent at an online casino. If you experience losses and your money starts to dwindle, no when to tap out and come back another day.

Choose Slots based on Variance and RTP – Consider what variance best suits the stake range. Whether you desire to play in low amounts with frequent payouts that are small amounts or in larger stakes that payout less frequently in large sums. Along with this, the higher the RTP rate the more you will win back per pound over the course of the game.

Pick a Free Spins Bonus or use Demo Modes – Free spins offers and demo modes give you the time to test out games before making a deposit. This is a great way to ensure your funds are allocated to the games you love and not wasted on a slot that is not to your fancy.

Self Exclusion & Time Limits – All slot casinos provide you with the ability to set time limits on your gameplay in case you are struggling to stop. Self exclusions also allow you to exclude yourself from a casino for a certain period of time to give yourself a break from online gambling.

Utilising these healthy practices will not only keep you safe while gambling online but also promotes better bankroll management giving you more opportunities to hit that jackpot.

Online gambling faced several challenges and incredible changes will continue in 2023. The progress in technological developments keeps speeding up and it’s more important than ever for online slot sites to embed the right technology. One thing is certain and that is that success in the online casino industry depends on effective marketing and providing services that are aligned with players’ needs.

Predictions indicate that cryptocurrencies might dominate the online gambling world as players are more secure and anonymity demanding. The habits of online players continue to shift and while services rise to the top, many realize and demand the safety and security offered by UK slot sites.

The demand for exceptional service standards puts pressure on new slot sites and existing online casinos to offer bonuses that are more valuable to new players and existing members. Game developers who crave success will need to dig deeper into their creative skills, while efficiency includes fast, caring and result-driven services.

The wow factor in entertainment is not shifting from outstanding visuals or sound effects, it requires even higher standards from slot games in terms of interaction. Live casinos will enjoy even more popularity and the best slot sites UK will place a new focus on retraining staff to develop the skills needed to work alongside smart machines while displaying unique human skills.

The Slot Buzz looks forward to 2023 which will focus on interpersonal communication, creativity and online casino players’ needs. 2023 could be the year highlighting humane qualities such as caring and compassion in the online gambling world.

Which is the best online slot site?

The best slot sites have a wide variety of games on offer from all the leading slot developers. They give a generous welcome bonus package including free spins on the best slots, and high-value deposit matches with fair terms. The top casinos also support a good range of payment options, including eWallets and pay by mobile services. We rate all the slot sites in our list here. One of the best currently operating in the UK is Leo Vegas Casino.

Which slot site has the best odds?

Slots and casino games payout according to the metric of Return To Player (RTP) which shows how much money will be paid back in winnings from all the money wagered. This is a theoretical and average rather than an absolute value and it will change from session to session. It is similar to the odds of winning. A game with a 95% RTP will pay back £95 in every £100 wagered. Online casinos sometimes publish the aggregated RTP of all their games each month. To find a casino with the best odds you should look for one which offers lots of games with a high RTP.

Which slot site has the biggest payouts?

The payouts of a casino are determined by the games they offer. The highest payouts come from slots that have a big win potential or offer big progressive jackpots. You can always find the payout potential of any game in the information screens that appear after it has loaded. This website reviews games with the biggest payouts, including Lil Devil by Big Time Gaming and Progressive Jackpots like Mega Moolah.

Can I win real money playing slots online?

Yes, it is possible to play slot games and win real money at licensed online casinos in the UK. In order to win real, withdrawable cash you will need to deposit using a debit card, or an eWallet service like Paypal. Most slots can be played from 10p up to £100 per spins (sometimes more) and offer payouts into the £1,000s. If you do win you can withdraw the money back onto the card or eWallet system you deposited with.

What is the best slot game?

There are thousands of online slots games to play at UK casinos. The very best ones have exciting themes and beautiful graphics mixed with thrilling gameplay and big potential payouts. Everyone has a different opinion on which is the best but the most popular include Starburst by NetEnt, Bonanza by Big Time Gaming, Mega Moolah slot and Immortal Romance by Microgaming at online slot sites. Our site reviews and rates hundreds of games so you can make an informed choice on which to play.

Can I play video slots online for free?

It is possible to play slots online for free. However, since May 2019 it is necessary to first register and verify your age at a casino before you can spin the reels. This regulation was introduced by the UK Gambling Commission to prevent under 18s from experiencing slot play before they are legally old enough to gamble with real money. When you register at a gambling site you will be required to enter your name, address, email and date of birth. This will be enough to allow the operator to verify your age.

Where can I play a progressive jackpot slot?

Most online casinos will have a suite of progressive jackpot slots to play. Some have small prizes and drop their jackpots weekly or even daily. Others have multi-million GBP prizes that pay out infrequently but set records when they do. One of the best is Microgaming’s Mega Moolah. We recommend playing progressive slots at a Genesis Global casino called Casino Gods.

Which slot sites offer free spins with no wagering requirements?

It is now possible to claim free spins offers from casinos where the winnings are paid out in cash which can be withdrawn immediately. That means no wagering requirements. These free spins will usually be available on low variance slots like Starburst. Currently, you can claim up to 50 spins when you make your first deposit at Play OJO casino with no win limit and no wagering requirements (see site for terms).

Are online slots fair?

Yes, online slots are fair. All online casinos taking bets from UK-based gamblers must hold a license from the UK Gambling Commission. The developers who create the slots must also be licensed. Under the terms of these licenses, all the games must be audited and tested to ensure that they are fair, safe and secure. The use of Random Number Generator (RNG) technology ensures that the outcome of every spin is totally random and cannot be affected by activity outside the game engine.

Can I play slots on mobile?

More than half of all wagering on online slot games is now made on mobile phones. Game developers use HTML5 technology to ensure that each slot game and all their products are optimised for all devices. The games look best on full-screen phones and it is possible to sign up, deposit and play online slots entirely from a hand-held device. There are also now payment services that allow players to deposit through their mobile without the need to use a bank account. Payments are added to the customer’s monthly phone bill or deducted from their pay as you go credit balance.
