With so many UK slot sites to choose from, it is easy for UK players to find themselves stuck between a wealth of different options.
While it can sound easy to pick out the best option from a list of online slot sites, many people find it overwhelming, and that overwhelming feeling can be very demoralising.
At The Slot Buzz, we review a wide range of online slots sites to try and pick out some of the best in the UK, helping online slots UK players find sites that they know they can rely on. But how can you tell a good site from a bad one, and how do our reviews help make the final decision much easier?
Below is a list of some of the best slot sites UK players can enjoy right now. Of course, when it comes to online slots sites, there is not always a single “best” option. In the end, the choice comes down to a lot of factors: personal preference, your favourite slot games, and the kind of atmosphere you are looking for.

When we review UK slots sites, we are not taking the process lightly. It would be easy to look at online slot sites and give them a basic rating after just a quick glance at the site, but most slots sites are a lot deeper than they initially seem.
If you are looking for new online slots sites to enjoy, then you do not just want to know if a site looks good or offers a wide range of games. A single small change between two similar slot sites can completely overhaul how the entire site feels and performs as a gaming space.
Like all casino sites, the idea of the “best” online slots sites can change depending on the person. If you are looking to play slots online, then you will have your own specific idea of what the best online slots experience would be.
While we can’t account for every single player’s unique tastes, our reviews are based on factual details: things like reputation and game selection.
If you want to play online slots in a space that you can trust, then looking at the factual details can be a major part of choosing a good site to call home.
We base our reviews on a range of important criteria, such as:
Slot sites need to be licensed and registered properly to operate in specific countries, and a site without proper licensing and registration may be acting illegally. Not having any oversight can also mean that a site is not going to follow rules and laws that are meant to protect vulnerable players.
A site’s reputation can say a lot about the experience that customers have had with them. Slot sites with great reputations are usually known for being accommodating, fun and accessible. Slot sites with bad reputations may have engaged in shady behaviour or conducted themselves poorly.
A site without good security can be a huge risk. Better site security means that customers are more protected, preventing data theft or account hijacking. This can also be important for keeping your payment information safe, especially if you are paying directly from a bank account or card.
While more games do not make a better site, having a wider selection of games can still be appealing. More games provide more variety, keeping the site from getting stale. While some players will only focus on one thing that they enjoy (like classic slot games), there is not usually a downside to having greater game variety.
Bonuses and Promotions
Promotional features and bonuses can directly impact a player’s experience with UK slot sites. Good bonuses and promotions can give new players a boost while also giving long-term players a reason to keep engaging with the site. Bad bonuses may deflate the excitement of earning a bonus or actively make the experience worse.
A site that accepts more payment methods is generally going to be more convenient to play at since players can use a diverse range of payment options. While this is not always a deal breaker, some players are only comfortable using certain deposit and withdrawal methods – so finding sites that match can be important.
Without good customer support, an online slot games site can struggle to protect and support players. Good support gets issues resolved faster and allows for easy communication, while bad support may be so slow and restrictive that players are barely getting any help.
Some slot sites offer responsible gaming advice and features, helping to support players who want to carefully regulate their spending. Even if you do not need these features yourself, they can be an indicator of a good slot site that will let players take a step back if they need to.
Terms and Conditions
Terms and conditions are often overlooked, but they can make or break a slot site. This is especially true of bonus features – if a site’s bonus spins have incredibly strict limitations on them, then those bonus spins can become far less appealing to new players that were considering the site.
Payout rates are another aspect that gets overlooked easily, despite being directly tied to the winnings you are likely to earn. While payout rates are mostly consistent across a lot of sites, knowing the chances of payout rates between major online slot games and slot sites can still give you an idea of what to expect.
These are not all the factors that go into our reviews, either. We also take into account things like site design, navigation systems, and the general experience of playing online slots on that site.
There can be a lot of specific details that might change how an online slots site feels to a user. While we can’t break down every single tiny detail, we want to cover as much as possible, helping players find the best online slots sites in the UK based on their own personal needs and preferences.
Remember: the site you choose will impact how you play online slots. You can’t just ignore the technical and functional quirks of new slot sites – things like bonus spins and welcome bonus features will alter your experience, as will the game selection and the terms behind using bonus spins that you have earned.
Top 5 Online Slot Sites in the UK – Our Picks
We try to cover as many UK casino sites as possible, picking out the best UK slot sites and giving them the spotlight that they deserve.
However, the world of slots sites is always changing, and new sites are always appearing out of thin air. Sometimes a particular site sticks out or distinguishes itself from others, and our editors occasionally find slot websites that feel worthy of mentioning.
Below are five slot site options that our editors have taken note of. Whether they are some of the best or just unique enough to deserve more attention, these five can be a great place to start your search if you are wanting to dive into exploring new slot sites that you might not have heard of before.
Live Betting -Allows players to enjoy live markets for a range of casino games that have constantly changing odds and unique casino bonus features.
24/7 Support -Giving players an easy way to get help for account or payment issues using either email messages or the live chat system.
Randomly Supercharged Odds -Randomly giving players a massive boost in odds to keep casino games fresh and varied. This occurs at random, and these "Kwiffed" odds can happen to almost any bet.
Limited Payment Methods -Forcing players to use only one or two potential payment options for funding their account on the slot site.
Limited Markets -Meaning that casino games and sports betting players do not have that much variety compared to other online casinos.
Plenty of Jackpots -Giving slot games players even more slot bonuses via the jackpot system. This applies to classic slots the most, letting both new players and veterans achieve huge wins if they get lucky.
Great Game Selection -With countless carefully-selected games that all have their own bonus features and special promotions.
Desktop and Mobile Functionality -Letting you switch between the two platforms and keep using the online slot site almost seamlessly.
Limited Promotions -Meaning fewer bonus features from outside the game bonus spins themselves.
No Crypto Support -Meaning that crypto payments are impossible for people who prefer to use cryptocurrency and other digital currencies.
Cashback System -Allowing players to claim money back if they commit to playing at the site for a longer period of time.
Great Bonuses -Including bonus spins that have no free spins wagering requirements. This is very uncommon among slot sites that offer bonus spins and a nice change for new players.
Full App Compatibility -Letting mobile users visit the site through a dedicated app rather than having to use their browser.
Small Game Selection in Certain Game Types -Although the slot site may slowly start to expand its option over time.
No Traditional Welcome Bonus -Since most of the bonuses come through the cashback system, wheel spins and the loyalty program.
Varied Payment Methods -letting players deposit and withdraw in a range of ways to suit their personal preferences and needs.
Mobile-Optimized Site -Meaning that you can jump into the site on mobile via your browser and still get the same experience.
Live Casino Games -Open up more ways for players to enjoy live games at their own pace.
New Site -Meaning that Spin Rio still needs more time to flesh itself out and reach the same heights as other slot site options in the same general niche.
No Loyalty Scheme -Meaning that most bonuses are random and are not based on player loyalty or long-term playing.
All British Casino
Excellent Bonuses -Including a 100% match bonus and a 10% cashback feature to make your money go further.
Varied Slot Options -Letting you enjoy a range of slot games all on one site. This includes a variety of classic slots, as well as more modern casino slots with unique features.
Simple Loyalty System -Providing points for every £5 the player deposits. This gives you a deposit bonus without the extra confusion and flair of a larger-scale loyalty or VIP system.
Niche Bonus Options -Since features like the cashback system require specific circumstances to activate and have to be turned on manually rather than being an automatic benefit.
No Support Early In The Morning -Meaning that late-night players may run into account issues and have to wait for support to become available again.
Remember that the sites listed above are just a fraction of the slot options offered in the UK. With so many different casinos to explore and slot sites to choose from, it can be incredibly difficult to nail down an option that suits your needs best.
We review a huge amount of slot sites every month, but there are always more coming. If you do not know which slot sites are right for you, be sure to check out our recent reviews to get more details on new sites that might have just started up a few months ago.
While these are the top-five picks of our editors, it is also important to remember that slot sites are very person-specific things. When you are playing online slots, you have an idea of the experience that you want, and not every UK slot site is going to appeal to every person.
How to sign up to a slot site in the UK
In general, signing up for online slots sites is relatively easy. However, a lot of these slot sites also have their own unique quirks with how the sites themselves work, and there may be specific steps you have to take before properly signing up.
In general, most slot sites are going to follow the same standard sign-up process, throwing in a few extra details here and there depending on what they need new players to actually do. Sometimes the extra steps are for major legal reasons, and sometimes they are simply for the site’s benefit.
If a site requires you to do something before you can play, then you will need to do it. Be sure to look into each site’s specific sign-up requirements if you have concerns about keeping your data private, but remember that you will almost always have to verify your identity before you can play slot games.
What You’ll Need
While you do not need to prepare for the sign-up process, it helps to have the potentially-required information ready. This allows you to streamline the sign-up process since you are not stuck scrambling around for a specific document that would verify your identity.
To comply with key regulations and laws surrounding money laundering and identity theft, slot sites require you to verify your ID and address. This generally requires a passport or driving licence, although you can sometimes also use legal permits or documents that work as proof.
An alternate way to verify your identity can be through bank statements and financial documents, like utility bills and HMRC letters.
Sites will expect clear photographs or scans (or even physical copies) of the documents, and they have to be unedited and uncensored/not cropped. Setting up your payment method ahead of time is a convenient way to prepare.
Even the best online slots sites will often require you to connect a payment method before you can engage with games properly, even if you qualify for the free bonus money, so preparing your payment information ahead of time can speed this up dramatically.
Finally, prepare any codes you will want to enter during registration. Depending on the site and its login platform, you may need to input this code at a different time – sometimes at the beginning, sometimes at the very end, and sometimes halfway through the process.
Find The Site Registration Page
The easiest step is to get to the site’s main page and find the login/register buttons or links. Each site will have these in a different place, but they are generally at the top-right of the page somewhere.
Sites on the same network and/or basic site platform will usually use the same basic layout, so you can often find the login and register options quite easily.
If you can’t, for whatever reason, simply try to open up a game. Most sites will present a warning that you need to log in to play, which should then lead you to a login and register page.
Enter Your Details
Entering the required information into the registration pages should be quite straightforward. Most sites will tell you exactly what they need from you, and you will often have to go through two stages of forms (the first one is usually things like your birth date, while the second one is more in-depth information).
After that, you will usually have to create a username and password. While you can generally reset these after signing up, you will still want to choose something that you can remember easily or at least something that you have written down/saved elsewhere.
Make sure to check any tick-box fields that you might be shown, too. Some might be mandatory, like agreeing to the terms and conditions. Others might be opt-ins for a newsletter or some other feature of the site, so you will be able to choose whether or not you want these extra emails.
On many sites, you will also have to complete a captcha test. This is a check to prove that you are a real user and not an automated bot, and the tests themselves can vary since they come from an outside provider. However, most people should be able to clear them just fine.
Verify Your Identity
It is important to verify your ID when signing up for online casinos, ideally, as soon as you can. If you do not verify your ID, then you generally can’t play, which means that you are only able to access the site itself (and any completely free games they might offer).
Note that not verifying may also restrict you from claiming a welcome bonus. Even if the welcome bonus is completely free rather than a matched first deposit bonus, you will not be able to earn or use the welcome bonus until you have proven that you are a real user.
If ID issues are found (such as your ID already being used on the site or not matching the other information you have provided), you will have to talk to the support team. If you already have an account on the site and forgot about it, support may be able to help you recover it.
Verifying your ID can take a while, so the sooner you can send over the right documentation, the better. If you wait too long, you might miss out on a welcome bonus that you wanted to earn. Having the documents ready ahead of time can make this a lot easier.
Attach Payment Information
While you will sometimes have to do this before verifying your ID instead of after, you will always need to supply some payment information. Again, you generally can’t play casino slots without valid payment information, even if you use free welcome bonus spins.
Remember that you may be limited in which payment options you can use. Each online casino (and online casino network) will only accept certain payment methods
If you are using a payment method that is deposit-only, then some sites will transfer withdrawals to your bank directly. Others may require you to use payment options that can handle both withdrawals and deposits or allow you to set up a different method for each.
Remember that different payment options may have their own requirements and restrictions, including minimum deposit and maximum deposit limits. Beyond this, you may have to verify the payments within your payment platform, too, since some will flag up unexpected payments to gambling sites.
Once your payment methods are attached and verified, you can usually make a deposit straight away. Just remember to double-check all payment options and account information to make sure that you got everything correct.
With everything sorted out, you should have your account primed and ready to use. You can start playing whenever you feel like it or explore parts of the site that you were not able to access when you were not logged in.
It can be a good idea to check out optional features like deposit limits and responsible gambling options, too. Taking a look at your account features and settings may help you understand what kind of options you have available, which can be helpful to know in the future.
Whether you start playing right away or spend some time exploring the site, you should be free to access most of its features and pages. Take some time to get used to how the site works since many pages are often shut off unless you are actually signed in.
Guide to Playing Online Slot Games
Even once you have found a slot site that you like, a new player (or an out-of-touch veteran player) will need to be prepared for the slot games themselves. If you want to have a good experience playing slot games, it is important to know how you are meant to play them, after all.
CHECK THE PAYTABLE
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.
SET THE STAKE
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.
Like most casino games, there can be a lot of nuance to playing even the most basic classic slot games. Jackpot slots and other modern varieties of video slots can involve even more rules and features that might complicate things further.
If you are interested in learning how to play slot games properly rather than just making random bets and hoping that you will win, then we have broken down the key points behind getting the results that you want. A slot game player should always be prepared, and understanding the slots themselves is a key part of that prep work.
Online Slot Variations
A single slot site might host dozens of general online slot game variations, each one encompassing a range of games as a whole.
While most people know the basics of a typical video slot game, the truth is that every few modern games are typical. If you are playing slots at random, there is a good chance you will run into a feature or bonus that is not part of classic games.
It is almost impossible to remember every single variant of all slot and casino games in existence, but knowing the basic general types can still be important. Many of the best slot sites offer a good variety of games, so you want to know the most popular archetypes and categories.
Classic slots are the three-reel slot games that most people think of when “slots” are mentioned. These work like the one-armed bandit machines that a lot of people remember fondly, only translated into a digital gate.
These are simple and easy to bet on and often show results quickly, meaning that they are a popular choice for online casino players who want something straightforward.
Most classic slots will use various symbols to mark winning conditions, as well as a jackpot symbol that the player would need to match three of to get the big win. With only three reels, the combinations are limited, but the spinning itself is fast.
There is not really any particular quirk that you need to know regarding these machines. They are incredibly common on any slots site, and most features are going to be simple things that the game itself can explain.
Playing classic slots is simple: since there is usually just one payline, you just spin and hope that you get a winning combination in the middle of the reels. Bonus spins are basically going to be more of the same, and only a few will have features that drastically alter the game itself.
Video slots are generally five-reel slots that take things up to the next level. While the five reels mean more combinations as a whole, they are also usually packed with more features and bonuses, as well as opening up more paylines that can influence the kind of wins you earn.
Video slots also tend to put more effort into presentation, using stylish graphics and animation to draw in users. The theme can be important since it influences all of the symbols, the music, and even the choice of bonus features in some cases.
The main point of video slots is to take full advantage of the digital improvements they have over classic slots. This means more bonuses, flashier visuals, greater variety, and a widespread presence in any online casino.
However, playing these games is still relatively simple. While the extra paylines (three main win rows and some alternative “slanted” paylines) can vary things up, you are usually just spinning like normal.
The real change is bonuses. For example, when playing slots like this, you might activate a hidden bonus feature by getting specific combinations of symbols. This could just be free spins, or it could be an entirely separate bonus game that has its own set of gameplay rules.
For example, you might get to spin a large wheel that contains bonuses like 50 free spins or a small cashback amount. Others may provide you with a varied amount of free spins based on the amount you won or even offer you free spins with a chance to boost your last win amount.
Megaways games feature six reels and a rotating set of symbols, meaning there are a huge amount of paylines with each spin. The number of paylines on offer can vary between 243 and a huge 117,649 patterns, making every spin extremely unique.
These are larger-scale slots that many of the best slot sites offer as a main attraction. While Megaways games are quite rare (and are often Megaways-focused versions of selected games that were already popular), they can lead to a lot of winnings paid if you get lucky.
Megaways slots are notable for having even more intense bonuses. This can mean entire bonus rounds and unique in-play features, leading to more active slots bonus options and keeping the game fresh for a lot longer than standard slots.
Of course, this also makes them more complex to play and can put them under more restrictions. For example, bonus money may have extra steps you need to take before you can withdraw it as cash funds, and the slots bonus games may require you to play them in specific ways.
Many of the best online slot sites offer a good range of Megaways games, although they are obviously quite limited in number. They can be hard to learn as a new player but are often worth it if you want to play something more complex and with greater variety.
Progressive slots are slot games that have progressive jackpots as a core feature. These are jackpots that gradually build up over time, taking into account bets across the entire site (or even the network) until somebody wins that jackpot.
While these are still normal online slots underneath that, progressive jackpot slots are heavily focused on the progressive jackpots themselves. Players can earn a massive payout if they get lucky, and the jackpot keeps increasing as more people put money into the game.
These often become a central part of an online casino, with many larger-scale jackpot slots constantly gaining more money until somebody gets lucky. They are effectively the live casino games equivalent of slots since the jackpot rises and falls in real-time.
RTP & Variance
There are two main factors that go into how slots are compared to one another: variance and RTP. These are important metrics to understand because they tell you a slot’s chance of actually paying out – which directly ties to your chance of winning.
RTP, or Return To Player, is basically the opposite of the house edge. It is the amount of cash funds that players will earn compared to how much they are putting in.
For example, an RTP of 96% means that players, as a whole, will earn £96 in winnings for every £100 spent. This obviously is not spread out evenly, but it can still be a good measuring stick for how often a slot will pay out winnings to somebody.
Higher RTPs mean that a larger portion of the cash stakes will be returned as winnings. While no slots ever really reach 100% RTP for obvious reasons, higher numbers are still generally better.
You can usually find RTP information on a game’s page or in slots site and game reviews like our own. Be sure to consider RTP if you are getting used to slot games, especially as a new player who might want to choose online slots that are balanced in your favour.
Unlike RTP, variance is based on the frequency of wins. Most games fall into Low, Medium or High variance (also known as volatility) depending on how often they actually realise wins, as well as the average value of those wins.
Low variance games have higher-frequency payouts for less money. Winning is much more likely, but your wins are going to be fairly low, sometimes leading to a win being only a slight bit higher than your initial bet was.
However, these can be perfect for newer players who care more about frequent small losses than infrequent big ones. This can be a great way to avoid getting demotivated since you are more likely to win instead of having a constant losing streak.
High variance is the opposite – rare payouts, but they are big ones. This is high risk and high reward since you might go through a lot of deposits before you hit the big payout. This makes them somewhat similar to jackpot slot games on a smaller scale.
These are often played by experienced slots players who are well aware that the payout can be very worth it. However, new players are not often drawn to them since the risk of losing a lot of money is always present.
Medium variance is the in-between. These are not particularly high or low payouts, and the wins are somewhere between the other two options. However, they still have their fans, and they are a safe option for people who want more payouts for a fair amount of risk.
The best slot sites will offer a mixture of games at different variance levels. However, some sites are clearly geared more towards a particular level of variance, so it can be important to see which kind of games a site focuses on most before you sign up.
Best real money slots
Real-money slots are the typical slot games that you are going to find online since most online slots are meant for real money. If you want to know more about the best slots in general, then you can take a look at our reviews to learn more about various games.
Best free online slots
Certain slot games are able to be played completely free. While this is not all that common in most cases, our reviews will note situations where a site offers games for free or has a free version of a game.
Keep in mind that mostfree slot games will not let you win any real money. The exception is through free spins you earn as part of a bonus spins feature since you could technically earn money with nothing but free spins under the right circumstances.
Best PayPal slots to Play
PayPal is an extremely popular payment method for slots. In fact, it is so popular that almost no slot sites do not support it, hence many slots taking on the name “PayPal slots“. It has become a standard payment method for many gambling networks.
Of course, be sure to check our reviews (or a site’s payment info pages) if you want to be sure. It is better to be safe than sorry when looking into the payment methods you can use on any given site.
SLOT SITE GAME SOFTWARE
The software providers behind a slot site are important. These sites do not exist without developers providing games, and it can be important to consider the developers as well as the slots site itself.
Most developers offer their games to a range of networks, meaning that the same slot games can appear across a range of slots site networks. If you want to play slots by sticking to your favourite games, then looking into the developers that each site hosts can be useful.
BIG TIME GAMING SLOTS
Big Time Gaming was founded in 2011 and has taken the gambling world by storm ever since. Most notably known for their unique random reel generator mechanism, Megaways which you can find at all the best online slots sites in the UK. Online slots such as Who Wants To Be A Millionaire Megaways and Bonanza Megaways are just some of the hit BTG slots you can expect to play at slot sites.
Playtech is another giant in the slots world that has been operating for over two decades. They offer an array of classic slots, video slots, live slot games, and progressive jackpot slots. Known for flawless graphics and crisp audio, it’s no wonder such high volumes of slots fans play Playtech slots daily. This high volume of players allows Playtech to keep RTP rates at an astonishingly high percentage which is music to UK players’ ears.
YGGDRASIL GAMING SLOTS
Yggdrasil Gaming is a go-to for those who enjoy wagering at mobile slot sites. Unlike other software developers that churn out new games weekly to see a profit, Yggdrasil slots have ensured its customers receive a spectacle of animations upon each release.
Their RTP rates are just within the industry standard, where they shine through in bonus play in their wide range of games.
Available at all top slot sites, Microgaming software has become a household name in the iGaming world. Think back to all the online slot sites you have played at in the past few years. Chances are that Microgaming was present in force. They produce hit games monthly, amalgamating blockbuster movies and thrilling features into their video slots. If you enjoy slot tournaments or a daily free game, Microgaming often teams up with some of the best slot sites creating unique gameplay for all to enjoy.
Expect to play slots like Starburst and Gonzos Quest which we all know have amazing bonus features. These iconic casino games provided by the one and only NetEnt are often at the forefront of free spin offers at many of the best online slots sites in the United Kingdom. NetEnt also offers countless jackpot slot games, mobile slot games, and slot tournaments through online slots bonuses for their branded games.
SAFETY AND LICENSING AT SLOTS SITES
Bonuses & Promotions at UK Slot Sites
Promotions are important. Whether you are a new player or a long-time player looking for a new site, casino bonuses for slots players can often be a huge draw and can directly impact the winnings that come your way.
From a first deposit bonus that gives you free spins valid for 7 days to cashback on your cash stakes as part of a VIP system, a lot of online slots UK sites offer bonuses worth looking into.
Match bonuses give you extra money as a first deposit bonus. For example, a 200% match first deposit bonus gives you an extra 100% of your deposit as deposit bonus funds.
These bonuses effectively give you extra first deposit bonus money that you can use alongside your actual funds, allowing you to get some free spins (or plays on other games) with the free cash.
Note that this money may still have extra rules to consider. For example, you may have to use only bonus funds until you run out or be forced to use them as only bonus funds for particular games instead of the slots you were intending to play.
In most cases, bonus funds expire eventually. It is possible to miss out on the best slot bonus you have ever found due to being too slow on the deposit, and even the best online slot games sites will offer time-limited bonuses that never come back.
Free spins are simple. More free spins mean more chances to spin on slot games, and many sites offer easy ways to get free spins. Many games also have free spins bonuses built into them.
For example, deposit bonus spins may provide you with 50 free spins when you first sign up. These 50 free spins can be used before regular spins on selected games, giving you a whole 50 free spins to get used to the site and games on your own terms.
Again there can be restrictions: having deposit bonus spins winnings credited in a specific way or needing to use the free spins on only selected games. A games bonus win cap is often also applied, limiting the maximum amount that you can win per spin/bonus.
Wagering requirements are a major part of many bonuses. These wagering requirements basically mean that your bonus winnings will be locked until you earn enough to unlock them.
It is important to check the terms and conditions of a bonus that has wagering requirements. For example, a phrase like “30x wagering requirements” can mean that you need to deposit a value equal to 30x your first deposit and bonus funds combined.
This simply requires you to do it before the bonus expires, meaning that you can deposit this money over multiple days. In most cases, the requirement will count cash funds only, and wagering contributions will vary based on the select games you are playing.
Most first deposit bonus spins and benefits will have wagering requirements as a standard term, locking up your games bonus winnings.
Finding New Slot Sites
If you are looking for the best online slots to suit your betting habits, then it takes more than just comparing free spins offers and exclusive slots.
Thankfully, our reviews can make it easy to find the new slot sites for your personal needs. We go over each site in detail, mentioning selected games alongside live casino features, minimum deposit requirements, and anything else a new player would need to know.
Mobile Slot sites
Many slot sites are available on mobile, either through an app or the browser.
Apps are more convenient for getting the site to run consistently and can be designed to work well as a proper app.
Sites without mobile apps will instead usually use responsive designs that can adapt to screen sizes, meaning that the site should work in your phone browser just as well as it does on a desktop.
If a site does not offer either, then it may not work on mobile devices properly. This can lead to some major issues with getting the site to function correctly or function at all.
Safety & Security at Slot Sites
The best slot sites are not just the ones with low minimum deposit limits and high amounts of free spins. They also need to be able to protect you and your data.
The UK Gambling Commission requires a certain level of security for players. There are also standard encryption methods used by most sites like this, as well as dedicated security features employed by larger betting networks. You can read more about this in our Fair Play gambling guide.
Many sites also provide responsible gambling pages in accordance with groups like the UK Gambling Commission. These contain advice on how to play responsibly at gambling sites and often have links to other major resources.
Some sites in the UK will even allow players to restrict their own deposit amounts, making sure that they are not spending too much.
UK SLOT SITE FAQs
How Do Slots Site Free Spins Work?
Site-wide free spins are often meant for specific games. For example, if you earn free spins that are only meant for Sahara Riches Cash Collect, you most likely will not be able to use them elsewhere.
Can The Same Game Appear on Multiple Sites?
Most slot games are sold by their developers to a range of networks. For example, the Book of Dead slot by Play'n GO appears on many networks, so Book of Dead is available on sites within those networks.
This means that you could find Book of Dead (and any future variations of Book of Dead) on networks and sites that host Play'n GO games. While Book of Dead is only the example slot here, this is true of basically any slots.
What makes the best slot sites?
There is no single best slot site in the UK or even a best slot site in the world. There are so many factors in betting and slots that it is impossible to please everyone.
It is easy to get wrapped up in thinking that more is better and aiming for slot sites with a lot of live casino games - even if you will never play a live casino broadcast game.
Instead, think about what you want. Even elements like minimum deposit limits can influence who a site is targeted towards, and features like free spins on specific games might completely change the group of people interested in that site.
Are Free Spins Always Worth Getting?
In general, there is no reason not to get all of the free spins that you can. Even if you want to use normal spins, free spins are a great way to explore the site, and you do not necessarily have to use free spins to make money.
In fact, free spins are great for new players for this exact reason. Free spins give a new player a chance to get used to the site and some of its games without using real money.
Of course, some more experienced players may ignore free spins entirely to get right into the regular slots. This is not a bad thing - it is just personal preference.
Why Can't I Activate A Bonus Or Feature?
New players often do not realize that features sometimes have activation conditions. For example, many slots need you to make the max bet for a certain feature, and that means making the max bet amount multiple times if it does not activate.
On some slots, this might mean that you do not qualify for the progressive jackpot unless you meet the max bet amount. In other cases, it isn't the max bet but is instead things like your total deposit amount.
