Best UK Slot Sites Explained

Before we move on to types of slots, the best slot games software providers, and other nuances, let’s define the concept of “slots” and briefly explain how these games work.

All casino slots are played by spinning reels made of certain symbols (depend on a particular game.) Reels are also the columns of the slots, and the number of columns, as well as the number of row symbols, can vary. A user needs to press the spin button that controls the slot to spin the reels that will land in certain symbols. On real money gambling sites, you need to bet some amount of money before each spin wagering that they will end with lines of symbols. You win if 3 or more symbols line up along a pay line. Different symbols have different values – some can bring you a big win, and others will only return 50% of the money you bet.

Experts note that more and more users choose slots sites. UK players explain that this happens due to the following reasons:

  1. Playing slots is easy and fun.
  2. There are a lot of bonuses for players.
  3. The selection of games in the market is mind-blowing – playing slot games just can’t get boring.
  4. Some of them can be played for free.
  5. Most casinos offer high payouts.
  6. A lot of websites in the niche run slot tournaments.

Simply put, there are many reasons to choose such UK gambling sites. Slots are fun. Slots are profitable. For millions of players, it is a valid reason to choose slots over the rest.

How We Rank And Review Best Slot Sites UK

The fact that a company offers various online UK slots is terrific, but it is not enough for us. All the casino brands you can see in our ranking are carefully screened, tested, and then reviewed. What criteria are the most important for us? Let’s take a look at:

  • Licensing. This industry is commonly associated with risk. However, it doesn’t mean that the fun risk of betting and the risk of losing everything you have already won are the same things. The latter is exactly what people who choose unlicensed casinos usually face. That’s why we make sure that a casino has a proper license before we add it to our ranking of the best UK slot sites.
  • Transparency of the company’s policy. This is essential, too. Not all users agree to spend a lot of time reading boring info in the Terms and Conditions section, and though it is a wrong decision, we can understand them. It may seem that a website that looks good enough and seems trusted hasn’t got too much to hide, but our experience shows that it is not exactly true. We always pay a lot of attention to terms and conditions, in particular, to the fine line. This allows us to understand how transparent the policy of the company toward clients is.
  • Customer feedback. One cannot control reputation, especially when it comes to casinos. All precarious casino sites inevitably face the same problem – if the service is low-quality, the number of negative reviews will constantly grow. Well, bad news for bad casinos, good news for us. Our goal is to find all the customers’ reviews, analyze their feedback, distinguish reasonable complaints, and draw the right conclusions about the brand.
  • Bonuses. Bonuses are a great attraction; the way to encourage users, make them play slots. UK gamblers, however, can really benefit from such offers. No deposit & deposit bonuses, free spins can bring a customer a lot of money, of course, if wagering is low enough. Our goal is to check if bonuses are real (can be turned into real money after one wagers the amount a certain number of times).
  • Game selection. After our team checks all the things we mentioned before, we move on to the games. We consider diversity, but these are not the only important aspects – we also make sure the products offered on the website are developed by reliable casino software suppliers. Our experts also make sure there are different types of new online slots at the casino.
  • Usability of the site. It seems usability, as well as the design of the website, is underrated. Probably, they are less important than a license or reputation, but they matter. A user will never spend much time on a puzzling, horrible-looking, or just annoying website. We exclude low-quality websites from our list – they can hardly provide a genuinely good gambling experience.
  • Mobile optimization. The site itself, as well as the games, should be optimized. A significant part of gamblers worldwide prefers to play on their mobile phones and tablets. So, it is important to make sure that everything is compatible with Apple and Android devices.
  • Payment options. Why win money if you cannot spend it? Users often face difficulties with withdrawing money, and that’s why we make sure there are various ways to deposit and withdraw cash. Our team also focuses on the max and min withdrawal amounts, lengths of the pending period, additional conditions, and pitfalls, i.e., on everything related to real winnings. In our ranking, you won’t find a single company that offers bad payment conditions to a customer.

We carefully inspect casino brands, considering all of the above-mentioned criteria to select the best online slot sites. UK and global casino sites have much to offer to their users. People say casinos are created only to provide their owners with a stable income, and we agree with that. But we also know for sure that if a company is honest and aimed at providing high-quality gambling services, both parties can benefit from this experience. Our goal is to find all of them and share this information with you.

Types Of Online Slots

There was a time when there were only 3-reel slots. They were not too diverse or incredibly entertaining, but they worked well enough for the time. Classic 3 reels are still presented in the market, but more modern and fun 5 reels with tons of unique features and multiple pay lines are definitely the champions in the niche. The variety is just overwhelming, filling every category and subcategory of online slot games. Below, we describe the most common and popular types of slots in Great Britain, as well as in other countries.

Video Slots

Blood Suckers Slot


Book of Ra Deluxe Slot


Dead or Alive 2 Slot


Video slots are the modern alternatives to mechanical slots. A vast majority of slot games fall under this category. A user sees everything on the screen, and RNG determines the results. There was a time when players were skeptical about them mostly because of low-quality imaging, only 3 reels, absence of animation and sound effects. Today, they have it all.

3D slots

Dead or Alive Slot


Enchanted Prince Slot


Fire Joker Slot


Generally speaking, the 3D slots are the same thing as video slot games. There is the only difference – a user meets 3D animated characters that make the game more fun and entertaining. Such games have a plot, a storyline, and that, along with the top-quality animation, make them stand out.

Progressive jackpot slots

Jack and the Beanstalk


Jumanji Slot


Moon Princess Slot


It is all about team spirit, right? If you agree, you might be interested in playing UK casino slots with progressive jackpots. Every user playing the game increases its jackpot. Therefore, the more players join, the bigger the pot is. When someone wins it, the process starts again. Winnings here may be more than just impressive – there is a case of one of the users winning more than 11 million pounds.

Branded slots

Mustang Gold Slot


Shaman’s Dream Slot


Steam Tower Slot


Branded slots are themed video slot games. Yes, it is this simple. However, do not underestimate them because they are one of the reasons why online slots became popular. Guns N’ Roses, South Park, and Leprechaun, and The Games of Thrones – you will find all of them in a good casino that offers a wide variety of themed games.

Fruit machines

Reel Rush Slot


Reactoonz Slot


Fire Joker Slot


There is no big difference between fruit machines and other slot games, but still, they often are in a separate category. The thing is they have nudge and hold features – a gambler can choose which reel they want to move or hold when re-spinning other reels. As the category suggests, fruits are the most common symbols on the reels in such games.

Bonuses You Can Get By Playing Online Slots

How can a user distinguish between decent British or non-UK slot sites? There is one thing they have in common – they offer great bonuses and actually pay them. Let us take a look at the main categories of special offers you can find on niche websites.

  1. Welcome bonuses. This is the biggest category of bonuses. The reason is simple – brands want to attract and encourage new gamblers by offering very generous bonuses, the most common of which are described below.
  2. Reload. Reload bonuses are gifts offered to regular users who stay with a casino for a long time. That is great news for everyone who is genuinely interested in gambling – such facts prove you can expect generous bonuses not only as a new member.
  3. Free spins. 5, 20, 50, 200 free spins – one can find casinos with different offers. They allow users to spin the reel for free, and even win real cash, of course, if a player meets the wagering requirement.
  4. No deposit vs. Deposit bonuses. Bonuses offered by such companies can be divided into two groups: no deposit and deposit bonuses. The first ones require making a deposit: a user joins the site, deposits a certain amount, and gets x2, x3, etc. bonus and/or free spins. The second ones can be received without making the first payment – you only need to sign up and get your spins and/or a certain amount of money for registration and nothing but registration. Please note that in most cases, casinos set specific wagering requirements that determine how many times you need to win the amount of bonus to withdraw your money.
  5. “Best slot sites No wagering UK,” now that’s a common google search. These are the rarest and the most generous offers. The thing is there are no wagering requirements, and therefore, a user can get a bonus for sign up/1st deposit, etc., use it, win, and withdraw. Yes, that is all. In fact, slot sites offer real money, hoping that a user likes a brand, its hosted games and become a constant customers.

There are many kinds of bonuses one can get for playing online slot games in the UK. For example, some companies provide free spins to those who log in on Sunday. Why not? Some brands offer to reload bonuses to those who play particular slots. Nearly all players get free spins for registration. The number of variations is almost endless. However, no one should blindly trust a company. That’s why we check every casino and pay a lot of attention to wagers. Who needs a bonus if you have zero chance to get it?

Online Slots by Software Providers

Some people believe that casino games devs are no names. It may seem they are like tens of thousands of mobile app software providers — you can use the app, it may have millions of downloads, but you hardly know the name of the company that created your favorite application. In online gambling, things don’t work like that. Here, we have recognizable, valuable brands that are strongly associated with the highest quality and amazing experience.


This brand’s name is the first thing that comes to mind when someone mentions big names in the gambling industry. It is the absolute champion, the oldest and the most successful supplier of top-quality software. It was launched 26 years ago, and this was the first company to create mobile gambling software. Currently, Microgaming has more than 800 games in different categories, including slots. It is licensed by UKGC, a commission known for its strict rules and requirements. Players can be sure that playing is safe when you see a Microgaming logo. It is a global company, and its products are fully customizable. A lot of currencies and languages are available, too. What about Microgaming slots? British adult users can enjoy such top-quality products as Hitman Online, Jungle Jin Eldorado, Jurassic Park, Avalon, and many others.


Another pioneer has already developed over 700 casino games. By the way, Playtech is also licensed by the UK GK, so users can trust it. The company has decades of experience and a wide selection of products. But what else does it have to offer to a gambler? There are a few more important benefits; in particular, amazing optimization (Playtech games are compatible with any devices), innovations, and updates. Little Britain, Battle Of The Gods, Gladiator, A Night Out, and Batman are some of the most popular games in the United Kingdom.


Nearly all trusted British casinos, as well as in other countries, offer a lot of NetEnt games. The system of this supplier handled almost 60 billion transactions last year. Currently, the company works with more than 1,000 employees all over the world. Over 200 top-quality online slot sites purchase NetEnt software. The developer has over 200 amazing, incredible branded casino games, including Twin Spin, Gonzo’s Quest, Jumanji, Wild Wild West, South Park, Guns N’ Roses, etc.

Play’n GO

This well-established and reputable slot supplier focuses mostly on the quality and selection of games, safety, and customization. The variety of slot games is impressive: the company offers lots of video slots available in more than thirty languages, for example, Troll Hunters, Leprechaun Goes Wild, Wild Blood, Hugo’s Adventure, etc.


International Game Technology is one of the oldest companies in the market — it was the major supplier of casino equipment in the 50s and one of the first companies that entered the online gambling industry in the 2010s. It focuses mostly on video slots — over a hundred games offered by a company fall under this category. Today, it is the largest global supplier of slot machines and progressive jackpot games. If you are looking for the best online slots in the UK, try Pharaoh’s Fortune, Family Guy, Nordic Heroes, Western Bellers, or any other of hundreds of great IGT slots.


This company was founded more than 40 years ago, and it remains one of the biggest suppliers — in 2018, it had a turnover of about 5 billion euros. Currently, it has subsidiaries in more than 50 countries, is one of the biggest employers (over 30 thousand employees worldwide), has about 230 thousand terminals, and offers a wide selection of top-quality slots. A player from any country can find the slot that fits demographics best and meets all the expectations. For example, Book Of Ra, Amazon’s Diamonds, Big Robbery, and many other games are available to British players.

Tournaments On The Best Slot Sites

As its name suggests, a casino tournament is a competition. Users who want to take part in it need to bet and play slots. Yes, it sounds easy, but there are a few important things you need to know about such tournaments.

Firstly, you cannot take part in a tournament without making a bet. There is the so-called entry fee, which is also part of the winning. The player who takes first place on the leaderboard takes the biggest prize. Those who take second and third places get pretty generous rewards, too.

Sounds good, right? Tournaments are quite popular because they provide a unique opportunity to get an even more exciting experience and, yes, get big money from a website (or other participants, to be exact.) Here are some other reasons why users worldwide still consider tournaments some of the best entertainments in online casinos:

  1. It is one of the ways to get big money on a UK slot site.
  2. Participants play the best and the newest games.
  3. It is fun to compete with others.

So, it is pretty clear why people take part in such kinds of competition. Still, it is essential to keep in mind that joining them makes sense only if you do it on one of the UK top slot sites. Otherwise, you cannot be sure that you will ever get your winning, even if you take first place on the leaderboard.

Websites Offering Slots With High RTP

There is another important thing we need to discuss. It is called RTP that is also known as the Return to Player Value or payout.

Let us explain. For example, there is a slot game Mega Joker by NetEnt with an announced RTP of 99%. In theory, it means that a user will get back 99% of the amount they wager, and a casino will take only 1%. We`ve reviewed some slots with the best RTP to provide you quality gameplay. For some games, it is much lower: 98%, 96%, 87%, etc. Another significant point must be explained: It is calculated not per wager but in general, over a min of 1,000,000 plays. RTP matters because it provides an opportunity to win more and to enjoy longer play sessions.

What is considered as high to player value? It depends. It is supposed that the high RTP is 97% and more. Let us take a look at the value offered by the top casino suppliers and offered by the top 10 slot sites UK.

Slots Payment Methods: How To Deposit & Withdraw Funds

Are you looking for the UK slot sites that take PayPal? Or accept a debit Visa card? Or maybe another e-wallet might be a much better option for you? No matter how generous bonuses are and how high the payout is, you will hardly be happy facing withdrawal problems. Fortunately, top slots sites in the UK offer a lot of payment methods. In most cases, they can be used to deposit, as well as to withdraw earnings. Let us take a look at the most popular categories of payment options.

  • E-wallets. Skrill, Neteller, and of course, PayPal are the legends in the market. Why? First of all, they work globally. The biggest and oldest systems work in 200+ countries, with lots of different currencies, and are available in any place with Wi-Fi. Another huge benefit of using this payment method is speed – the fastest payouts, including the same-day payouts, became possible due to the e-wallets. The most famous and popular wallets are available at the vast majority of sites where you can play online casino slots (UK).
  • Cryptocurrencies. The future is here, and experienced users know about it. Cryptocurrencies immediately became popular among players for plenty of reasons. First of all, it is nearly impossible to track a receiver. Secondly, if you use this method, you can get your crypto the same day and in most cases, the same hour. Thirdly, there are no extra fees. Finally, some casinos offer very generous bonuses to those who choose Bitcoin and other cryptocurrencies.
  • Voucher providers. PaySafeCard is the absolute champion among the so-called voucher providers. It is popular because casino players appreciate anonymity, and this company can provide it. Adult users can buy vouchers that have a certain value on a site and then just enter the code. High speed is another cool thing about it – the transactions usually take up to a day.
  • Debit bank cards. VISA, Maestro, Solo, all these cards can be used in an average slot UK casino. A lot of players still use them. For many of them, e-wallets don’t seem safe (this is an old habit or even a stereotype, though). Such transactions usually take 3-5 business days and are secure. The best thing is that often, there is no extra fee for UK residents.
  • Bank wires. If users don’t have a bank card or don’t want to use it for some reason, a straight transfer can be made. Yes, it usually takes more time than sending money by using any of the above-mentioned methods, but it is pretty safe, and that is why people still use it. Please note that sending money to your account takes up to 12 days.

Choose from Top Slot Sites UK

We’d like to emphasize that top UK slots sites are real. However, searching for something like “no deposit slots UK” and picking a random slot site is the wrong approach. If you are very, very lucky, you will find a good site with quality games and many payment options. The rest 8 of the 10 people would find suspicious casinos with tons of pitfalls in their policies. That is why we encourage you to spend some time learning more about slots (the most important info can be found above), screening, and testing sites.

If you want to start playing slots now, check out the ranking created by our reviewers. You will see only the best slots sites with the highest quality, the most engaging, and profitable slots! Keep your money close and Casinosters closer.

FAQ`s about Online Slots UK

What's a Random Number Generator, and is it reliable? Can I trust the algorithm?

RNG is what made gambling possible. Moreover, you will not even find a legal casino that doesn’t offer RNG games. A company obtains a license only after the commission tests the algorithm and proves that it is truly random. So yes, you can trust it if a brand is properly licensed and completely legal.

Where can I find the newest high-quality UK slots?

You can do it on the best online casinos in Great Britain. The best of them (casinos that were carefully analysed, reviewed, and selected by our most experienced experts) can be found on our website.

I want to earn some money? Can I win it playing slot games?

Yes, you can do it. The only thing you need to do is to find a good British online gambling site, deposit some money, choose a game, and bet. There is another alternative, though. You can also find a company that offers free spins as a welcome bonus, but don’t forget to wager it the required number of times.

Do free slots exist? How can I find them?

Yes, on some sites, you can find free games. There are tons of them, actually. Most of them do not require a download or sign up. However, if you want to play a free game and win some real money, you need to find a company that offers no deposit bonus and sets reasonable wagering requirements.

Is there any winning slot strategy I can use?

No, there is no such strategy. There are some useful tips and recommendations a visitor can use in order to significantly improve the chance to win. Still, these are just tips, and they can’t be a guarantee of success.

Can I play these games on my smartphone?

Yes, the vast majority of companies in the modern gambling market do every effort to provide the best mobile gambling experience to all users. Most modern products are available on mobile phones and tablets.

Can I play slots legally in England, Scotland, Wales and Northern Ireland?

Yes, you can. You just need to find a reputable, trusted, and more importantly, legal company. You can find licensed casino sites that have great security & privacy policies, offer high payouts and a wide variety of games in this category here.
