The Best UK Slot Sites March 2024

Updated March 12, 2024

Discover the top-rated slot sites in the UK this month, carefully selected for you from our extensive WhichBingo archive of expert slot sites reviews. We’re constantly researching and writing online casino reviews, so we think we know what makes a good place to play. While a great welcome bonus is, of course, an important component, we think there is much more that goes into making the best sites for UK slots players.

As far as we’re concerned, any gambling website that offers slots should be classified as a slots tie. There’s often a major cross-over between gambling verticals, especially with bingo and betting sites. In fact, you’ll find that most gambling platforms offer slot games in one form or another. This is especially so with bingo sites. Operators have found that slots can really compliment their bingo offering due to the fact that many of their players like to play them between bingo sessions. So when you see a bingo or betting site included in our slots section, you’ll know why!

If you’re looking for the best online slots and offers UK players can enjoy, you’ve come to the right place. Find out what you should be looking for, see an up-to-date list of our recommended slot sites, and see as the best sites with great deals.

How we review and rate the best slot sites

Our team registers with all of the sites that feature on WhichBingo, while also sampling the games. Why? Because we want to put ourselves in the shoes of gamers and get a true feel for a casino or slots site. It’s all about the experience after all.

But providing genuinely helpful reviews isn’t just about assessing game variety or the value of bonuses. It’s also about ensuring that the site is safe for players to use. Here are the key criteria we use to evaluate a website.

Safest Slot Sites Rating Criteria 1 – Certificates/Licensing

This is an absolutely key area and our main starting point. All online gambling sites that want to legally serve games to UK players must be regulated by the UK Gambling Commission. These games must also be tested by an approved agency such as eCogra. Therefore, we won’t consider any websites for inclusion on Which Bingo that don’t hold official licensing from this body. 

Safest Slot Sites Rating Criteria 3 – Customer Service

Customer service can be something of a hit or miss area, even for UKGC-licensed sites. So we pay close attention to this, looking at things like the number of contact options available, the extent of a site’s FAQ section as well as customer support response times.

Safest Slot Sites Rating Criteria 3 – Safer Gambling Measures

Safer gambling is really big deal, especially considering the effects of problem gambling. So naturally, we look favourably on casino or slots that clearly have the players’ best interests at heart. The provision of safer gambling tools such as self-exclusion and time-outs is of course a must.

Links to safer gambling resources such as GamStop are extremely important too. We also like those sites that include their own resources such as questionnaires and detailed guidance about safer gambling.

Safest Slot Sites Rating Criteria 4 – Bonuses

Bonuses can have a big impact on a site’s overall rating. Unfortunately, some bingo and slot websites still use ambiguous working in their terms and conditions. We don’t like this, nor do we like high wagering rules and/or harsh play-through time limits. Accordingly, we’ll mark a site down if we find any unfair caveats lurking in the small print.

Safest Slot Sites Rating Criteria 5 – Payment Options

For convenience, an online casino or slot site should offer players a good collection of payment and withdrawal options including standard banking methods and e-wallets. Withdrawal times should also be reasonable (ideally no more than 3 days).

Top Tips for Choosing the Best Slot Site

With so many options to choose from, selecting a reliable new slots site can be a potentially confusing and time-consuming business. However, Editor Anita and our team of reviewers have heaps of experience doing just this, and so we have put our heads together to come up with our top tips when you are looking for the best and most trusted slots sites to play at.

1)   Know your preferences

In our experience, it’s so much easier to choose an online casino or slot site when you know precisely what you’re looking for. OK, so it’s a given that all of our recommended slots sites are trusted. A lot of them also include generous welcome offers and top games from plenty of different suppliers. But once you’ve got past these crucial elements, subjectivity really comes into play.

For example, you might prefer simple old-school slot games with limited pay-lines and basic reel layouts. So it follows that a website with a good range of classic slots is probably going to be more to your liking.

On the other hand, you may be a fan of Big Time Gaming’s famous Megaways mechanic and/or popular variations. Thus, a website featuring a solid collection of Megaways or Megaclusters slots will probably be a must. And what about those of you who prefer progressive jackpots or elaborate bonus rounds? You get the picture.

With this in mind, we recommend you head over to our Slot Games page which is organised according to game type. It provides a quick and easy way to track down popular casino and slot sites that cater directly to your personal gaming preferences.  Also check out our Slot Game Providers section – very useful if you’re devoted to games from a specific slot developer. 

2) test the site on your mobile

Mobile gaming is where it’s at these days. Indeed, any iGaming provider that wants to survive has to put the mobile user front and centre. This means that the website has to render well and operate flawlessly without significant lag or error, across all devices, be it a mobile device or tablet.

While it goes without saying that all of the casino and slot sites listed on our pages are fully-responsive, even popular iGaming platforms can vary in quality when it comes to mobile usability.

So be sure to check a site on your mobile before depositing your hard-earned. It should be a red flag if a site that doesn’t display well, is slow loading or seems buggy.

3)   choose your bonus carefully

Welcome bonuses have taken a bit of a hammering from the UK Gambling Commission in recent years and rightly so. The introduction of socially-responsible regulations has put a stop to some of the nefarious tactics of old, including poorly-worded T&Cs.

The bonuses tend to be smaller too while no deposit free spin offers aren’t quite as prevalent. This isn’t of course to say that there aren’t any worthwhile bonuses and promos still to be had – quite the contrary in fact. But it’s still important to read the small-print before signing up to any deal. Pay particular attention to wagering rules and check how long you’ve got to play them through. Additionally, you should suss out if they’re attached to the bonus and your deposit. Keep in mind too that free spins can also be subject to wagering.

Information about the amount of bonus winnings you’re able to convert into real money is also present in the small-pint. Expressed as a ‘maximum conversion amount’, it can have a major impact on the overall value of any bonus deal.

All of these caveats can help to reveal the true value of a casino or slots bonus.

4)   check out the variety of games

In our book, it’s often a sign of quality if a website is able to offer a comprehensive portfolio of games spanning multiple niches. This might include computer-based table games such as roulette or poker, a live dealer platform, bingo or scratch-cards.

There are of course plenty of dedicated slot and bingo sites that come highly-recommended. But as far as your personal preference is concerned, the ability to offer players plenty of options in this area may make for a more well-rounded gaming experience. However, there are some sites that we feature here where slots are more or less the only game in town. Some might have a couple of standard blackjack or roulette games, or no table games at all (including no live dealer games), so if you spend any time playing live dealer baccarat for instance, or you enjoy video poker, then make sure the slots sites you choose give you the chance to play these games as well.

5)   ensure the deposit and withdrawal methods work for you

A top iGaming platform will provide you with an assortment of safe and convenient payment methods with which to make a deposit. This includes standard banking options such as credit and debit cards as well as e-wallet methods like Skrill and Neteller As we all know, the ways of funding your account at a UK slots site have significantly changed. This is why the number and range of banking options a casino offers have become increasingly important.

The majority of our featured sites accept PayPal and PaysafeCard, or enable you to Pay By Phone, so that any deposit you make into your online casino account is added to your monthly mobile phone bill (or deducted from your pre-paid balance). We are also seeing a growth in sites accepting ApplePay and GooglePay. What you will have to watch out for is that in many cases using these payment methods will exclude you from claiming any welcome offer that is advertised, so check the terms and conditions carefully.

In terms of making withdrawals, bear in mind that transaction fees may be applied to certain banking options. Check up on withdrawal times too – they can take anywhere from 24 hours to 5 days. You will find that if you have a Visa debit card many sites will offer you Faster Payment and that means you will get your money within 3 hours and often even quicker. There’ll also be a limit on the maximum amount you can withdraw in one go.

Like welcome bonus small print, it’s good practice to familiarise yourself with these little caveats.

6) Provide your id docs straight away

‘Know Your Customer’ regulations require all players to provide casinos with ID documentation. However, you’ll find that some casinos won’t ask for this straight off the bat. Nevertheless, we recommend you upload these immediately. It can help speed up the process and should prevent any delays when it comes time to making a withdrawal.

How are UK slot sites created?

Like the online bingo world, when it comes to slots UK players have an ever-increasing array of choices. A quick look at what goes on behind the scenes in the iGaming industry will help to explain why today’s players have so many gaming options.

When you sit down to play at your favourite UK slot sites, you might not appreciate the many different steps that are required to get these games onto your screen. However, it is always helpful for players to understand how the industry works, and all of the different elements that go into producing online slot games.

Essentially, there are three different sectors in the online gaming industry who each have different roles in the delivery of games to players:

  • Software developers — the studios that create, develop and produce games
  • Platform providers — the businesses that supply the games to slot site operators
  • Slot sites — the operators or brands where you play games online

In broad terms, what this means is that when you play at a UK slots site, you are taking part in a collaborative exercise rather than playing at a standalone site where everything is done by a single operator.

why you should choose a UK slot site

While every business ever created wants to generate revenue and profit you can be sure that if a slots or casino site is UK registered then your money is in safe hands and that the set up of the site has to meet strict rules and regulations to ensure you are treated fairly and that the games are all monitored and checked by various governing bodies, not just the UK Gambling Commission, but the likes of the Malta Gaming Authority and Alderney Gambling Control Commission. The role of UK slot sites is to host a safe and reliable online space where you are able to play games, and can be trusted to provide players with other services such as welcome bonuses, gamification features, customer support and more.

Why play slots online?

We classify anywhere where you can play online slots as a slots site. Both online casinos and bingo sites feature slots, and so we consider both of these to be in this category. Simply put, playing slots online (responsibly) is a fun way to the pass the time and possibly win some money. Convenience plays a part too. There’s no need to visit your local arcade or casino in order to enjoy spinning reels.

Our featured sites and the ones in our directories only include those that are licensed and regulated by the UK Gambling Commission, so you can be assured of having a safe and secure online gaming experience as well.

Slot sites bonuses

Unlike land-based venues, online slot sites run numerous incentives and bonus schemes to entice and retain players. These slots bonuses can take many forms — from a no deposit bonus, to deposit matches, to bonus spins — but whatever kind of bonus you pick up, it will be a way of getting greater value from your online slots playing experience. While caution needs to be observed before committing to a bonus, there are plenty of worthwhile deals to be had.

Exceptional choice and variety

Unlike land-based venues, you’ve got a huge amount of choices in terms of game collection. Some of the best online slot sites features more than 1000 different games. It’s also worth mentioning that online slots can take a myriad of forms; new innovations in gameplay and themes are being introduced all the time, so when you play slots online the choices are almost unlimited.

Play on the go

The vast and rapid improvement in mobile slots technology in recent years has meant that mobile casinos today offer a vastly superior gaming experience than that of a few years ago, so much so that many players now play almost exclusively on their phone or tablet. Being able to access high quality slots at any time, no matter where you are, is one of the main draws of mobile slots, and the range of UK slots sites who offer a first-rate mobile gaming experience is growing all the time.

Improved RTP

Online slot games generally have a vastly superior RTP (return to player percentage) than the slots you’ll find in clubs or land-based casinos. This means your bankroll goes further and you get far better value than you get when playing slots at a bricks and mortar site.

How to Sign Up to a Slot Site

Signing up/registering with a slots site is pretty simple and generally follows this path. First of all, click register/sign up.

You will then be required to enter your email address. From here, an email with a link will be sent to your email account. When you click this link, you’ll be taken to the slot site and asked to provide a username and password.  

Once you’re registered, you’ll be required to provide ID documentation as part of the KYC regulations. This means proving your identify and age.

KYC Requirements

Although the process may be slightly different between casinos, in order to play the games, you have to provide the following:

  • Photo ID (Driver license/passport)
  • Proof of Address (household bill/bank statement)

You might also have to prove that you’re the owner of your chosen payment method. We recommend that you upload the above documents immediately to save time. To ensure that everything goes smoothly, be sure to provide up-to-date information. In terms of processing times, some casinos can take up to 72 hours to verify your information, although it’s often a lot quicker. Much will depend on the documentation you provide and the individual operator.  

Our Expert Tips for You

Here’s a few tips to consider when playing online slots that don’t quite fit any of the areas above, but which are important when you play at any slots site.

Check the RTP Rate

Before playing an online slot, check the RTP rate. Ideally, you’ll want to play a slot with a high RTP – we’d suggest something north of 95%. But remember that the RTP of a game might not be the same at another casino.

Check the Volatility Level

You’ll want to check this given the potential impact it can have on your bankroll. Low volatility slots award frequent but smaller wins. Those with high volatilities pay out larger sums but less frequently.

Set Your Bankroll

Speaking of bankroll, be sure to set the amount of money you’re going to set aside for slot gaming. And don’t go over it!

Qualifying for Progressive Jackpots

If you want to be eligible for a progressive jackpot pay-out, you may need to deposit a certain amount. So check the game info screen. Also bear in mind that a lot of progressive jackpot slots feature lower RTPs.

Optimising Your Slot Tournament Gaming Experience

Slot tournaments are an enjoyable way to potentially win prizes. The concept is relatively simple. In order to compete, you’re required to accumulate points playing slots over a specified period. They’re offered by vast number of casino slot sites so tracking one down shouldn’t be too difficult. 

As is the case with all incentives, it’s important to read the terms and conditions. You’ll need to learn about:

  • qualification requirements (deposit or free admission)
  • the games included in the tournament
  • how points are collected
  • time and duration of tournament

slot sites faqs

Are online slots sites to be trusted?

You can if they are licensed. If you are in the UK, then make sure the site has a United Kingdom Gambling Commission licence. If you are not in the UK, then look out for licensing from a higher tier licensee, such as the Malta Gaming Authority, or the licence providers of Gibraltar or Alderney.

What’s the best strategy for playing online slots?

No. No matter what you might read on the internet, there is ‘no secret slots strategy that online casinos do not want you to know about’. Slots award wins randomly but are geared for the online casino to retain an advantage. If you do win playing online slots, it’s only down to luck and nothing more.

What will I win when I play slots?

Potentially, you could become a millionaire by playing online slots with progressive jackpots, but the odds of doing so are the same as the odds of winning a national lottery. Remember if you do win big, it’s only down to luck.

Are other casino games available at slot sites?

Most online slots sites will have casino games too, including live casino games. You should always be able to play blackjack and roulette at the very least, and some sites may have other games such as baccarat, casino poker and video poker.

Which is the best online slot site 2024?

That’s very much a matter of opinion most of the time! Everyone has different tastes, but the best online slots site are those with a high number of decent games, excellent support options, a range of newbie and ongoing bonuses plus a good range of options for deposting and withdrawing. What we can tell you is that Foxy Games was voted Best Slots Site in the 2023 WhichBingo Awards if that helps.

Can you name the slots site with the best odds?

No slots site can be considered as having ‘the best odds’. Each individual game has ‘odds’, or an RTP (return to player) as it is more properly known. Look for sites with a high number of slots with RTPs in excess of 95 percent.

Which slots give the biggest payouts?

Slots with high RTPS are the best paying slots, although there is no guarantee that any online slot will pay-out consistently. Looks for slots with RTPs in excess of 95 percent. Generally, the company NetEnt tends to produce slots with high RTPs, so look out for their games.

Are online video slots fixed?

Not at licensed online slots sites. All software companies MUST have their slots tested independently. Any company found to be operating ‘rigged’ slots risks a massive fine from the UKGC, as well as having their licence revoked. In short, it’s just not worth it.

Is it safe to play online slots?

While we should always be cautious about how we conduct ourselves online, there are very clearly defined steps that you can take to ensure that your experience playing online slots is as safe as possible. You’ve taken the perfect first step by checking out the sites featured on WhichBingo – we only feature UK licensed websites!

So, in a nutshell, only play at UK Gambling Commission regulated sites and be sure that any site you choose to play has adequate safe gambling tools for you to take advantage of should you want to limit your spend or time online.

We only ever review and recommend UKGC approved sites, but you can check a site’s status for yourself by taking a note of the registration number (usually located in the footer or on the About Us page) and then entering these details on the UKGC website. This will then confirm that a site is fully accredited and able to accept UK players.

Furthermore, the games at our recommended sites will also be independently audited and tested by third party agencies, such as eCogra, IGL or TST. Their role is to certify that the operation of games’ RNGs is fair, and to ensure that this information is easily accessible so that you can check it out for yourself.

A site should have clear and accessible policies in place with regard to responsible gambling. For instance, our featured sites all enable you to place limits on your deposits (either daily, weekly or monthly) or, if necessary, to voluntarily lock yourself out of your account for a pre-determined period of time.

Playing online slots should always be an exciting and enjoyable pastime, and that’s why we ensure that all of our featured sites have these sorts of mechanisms in place, so that your gaming experience is always a positive one.

Do high-ranking slots offer the highest RTP?

No, high-ranking slots do not necessarily offer the highest RTP. Return to Player (RTP) is a statistical measure of how much a slot machine pays back to players over time. While some high-ranking slots might have competitive RTPs, it’s not a strict rule. Players should always check the game’s specific RTP regardless of its ranking.

What could be the reason for potentially lower RTP in UK slots?

Complex and ever-changing regulations and taxes in the UK’s gambling industry can lead to lower RTP in slots. Operators must adhere to stringent rules to how they market the games and pay high taxes, including a 20% remote gaming duty on gross gaming yield. To compensate, some slots sites might reduce their RTP to maintain profitability within this harsh regulatory framework.

Do UK slot games differ from those in other nations?

Yes, UK slot games can differ from those in other nations due to regulatory requirements. The UK Gambling Commission enforces strict guidelines on game fairness, responsible gambling, and advertising. This can influence game design, features, and RTP to meet UK standards. For example UK slots can no longer include an auto-play feature, they must have a 2.5 second gap between spins and players cannot buy bonus features. These options will still be found on the same games when they are made available in other countries that follow different regulations.

We update the information on this page often, so check back regularly to get the most up-to-date information on everything to do with playing online slots sites in the UK.
