BEST UK SLOT SITES BASED ON CATEGORY AND GAME TYPE EXPLAINED

In addition to looking at the top slots sites in terms of overall rating, we thought we would also look at how they perform in other areas. Maybe you want to play a certain type of game, or maybe you are looking for specific slot features.
So, if you are looking for a slots site for a specific purpose, we have compiled guides for you. Below is a summary showing the best slots sites for a variety of different categories, please explore the guides for more details.
BEST PAYOUTS
The slot sites that have libraries of games with the best payouts are:
- PlayOJO Casino
- Skol Casino
- Videoslots Casino
We consider the best paying slots to be those with a potential payout of 49,999x or more. At PlayOJO you can play Mayan Wild Mystery, which has a payout of up to 125,000x your stake. Skol Casino is also a recommended site because of the number of slots in this category. You can read the full guide to slots with the best payouts here.
HIGHEST RTP
The slot sites which have games with the highest RTP are:
- Skol Casino
- All British Casino
- Monopoly Casino
The average RTP for online slots is between 96%. Therefore, we consider a slot game with over 97% RTP to be high. At Skol Casino you can play Book of 99. This slot has an RTP of 99%. All British Casino and Monopoly casino are two other sites that have slots with high RTP such as Ooh Ahh Dracula and Monopoly Big Event. You can read more about high RTP slots here.
BEST PAYPAL SLOT SITES
The best PayPal slot sites are:
- All British Casino
- Playzee
- Videoslots Casino
PayPal is widely used for deposits and withdrawals at UK slot sites. The downside is that not all sites allow you to claim bonuses when you make a deposit with PayPal. All British Casino is recommended as you can take advantage of their £100 welcome bonus as well as make free PayPal withdrawals. Playzee and Videoslots Casino are also good options as both allow you to take advantage of deposit bonuses when using PayPal. You can read a more detailed analysis here.
BEST MOBILE SLOT SITES
The best mobile slot sites are:
- Mr Rex Casino
- Casiplay
- Playzee
Mobile gaming has exploded in the last decade. To rank highly in this category, the slot site needs to have a good gaming experience for the most common mobile operating systems (Android and iOS). Mr Rex Casino is a great choice for this as you can play thousands of mobile slots directly in your browser with no lag. You can read more about mobile slots here. In addition, most mobile slot sites have their own free to download app in 2023. For more info, see our guide to UK slots apps.
BEST NO WAGERING SLOT SITES
The best no wagering slot sites are:
- Betfred Casino
- MrQ Casino
- PlayOJO Casino
Slots bonuses with no wagering requirements allow you to keep your winnings, unlike standard bonuses that often require you to play through the bonus money 35x or more. Due to the high value of these bonuses, only a few sites have them. Usually these are free spins that you get against a pre-specified deposit amount. If you are thinking of using them, read our guide to no wagering slots.
SLINGO SITES
The highest ranked Slingo sites are:
- Slingo Casino
- Playzee
- Mr Rex Casino
Slingo is a mix between slots and bingo, and the London based company Gaming Realms holds the license for this unique game mechanic. You can therefore only play Slingo slots at sites that have games from this game provider. Find more Slingo sites here.
THE LATEST SLOT SITES
Four new slot sites include Winomania Casino, Bet Grouse Casino, MrQ Casino and SlotStars Casino. These are the latest slot sites we added at SlotsHawk.com.
As online slot sites launch or change, we update our rankings and reviews accordingly. When we have reviewed a new slot site, you can find it here.
The main advantages of choosing a new site are that you can benefit from new bonuses, games and features. At the same time, established slot sites have had more time to build and develop their product, so that is something to keep in mind too.
HOW TO CHOOSE THE BEST SLOT SITE
Because of the number of options, choosing a slots site can seem complicated. However, this does not have to be the case. If you know what features to look for, you are more likely to choose the right one.
Here we share the key features that you should consider when looking for the best slot sites.
MAKE SURE YOUR FAVOURITE GAMES AND SLOT PROVIDERS ARE AVAILABLE
In our experience, it is always easier to choose a slots site if you are aware of the kind of games you prefer and the providers behind them. If you know what type of slots you want to play, you can simply choose a site that has them.
For example, if you are a casual gambler who plays mostly for fun, you want to look for a site that has a good selection of video slots. This is because these are easy to play and come with good chances of winning. Sites that have a variety of such slots usually have games from providers such as NetEnt, Microgaming and Playtech.
If you instead like a lot of action with the chance of high payouts, then you will like Megaways slots or jackpot games. In such cases, you should look for slots sites with games from Big Time Gaming.
If you prefer simpler games with a retro feel, you want to play at sites that have a lot of classic slots. On our online slot games page, you can read more about the different types of slots and the studios that produce them.
ARE THE BONUSES RIGHT FOR YOU
The UK slots market is extremely competitive. Therefore, slots sites are forced to work harder to attract new players. One way to do this is to give casino bonuses to new players who sign up.
These types of welcome bonuses can come in different forms. Slot bonuses that provide a certain amount of bonus funds to play for are common. You can also get other bonuses such as free spins and cashback. The true value of the bonuses often differs, so it is definitely worth checking the quality of the sign-up bonus before deciding on a new site.
However, you should not only look at the welcome bonus. If you plan to play more, it is also a good idea to check what bonuses and promotions are available to existing players. Some sites have loyalty programmes and regular bonus spins on selected slots.
When comparing slot site bonuses, you should look at the size, wagering requirements and maximum conversion amount, which means how much of the bonus funds you can convert into real money and then cash out. Which one is best for you depends on your playing style, but as a guideline you want to look for bonuses that have low wagering requirements and high conversation amounts on winnings.
PAYMENT METHODS AVAILABLE
Most slots sites have many different banking options for players to choose from. You can almost always use debit cards such as Visa and Mastercard. You will also usually be able to use a couple of e-wallets such as PayPal, Skrill and Neteller. Other payment methods accepted at some sites include Apple Pay and prepaid cards such as Paysafecard.
Each payment method has advantages and disadvantages. Debit cards can be used at virtually all slots and casino sites with ease, but offer low anonymity. E-wallets give you fast withdrawals, but sometimes exclude you from certain bonuses. Prepaid cards give you the highest security for deposits, but cannot be used to make withdrawals.
All options also come with deposit and withdrawal limits and in some cases, fees. This is important to check on the casino’s payment page before you make a deposit. There you can also see the withdrawal times for each method.
Which payment method is right for you depends on personal preferences. If you want fast withdrawals (0-48 hours), choose a slots site where you can use e-wallets. If you prefer convenience and simplicity, debit cards are recommended.
QUALITY OF MOBILE CASINO SLOTS
Playing slots via mobile casinos has become increasingly common in recent years. As a result, sites have optimised their slots for mobiles and tablets.
The optimization process may differ depending on the site. While some have created an app that you need to download, others allow you to play casino games and slots in your mobile browser.
If you plan to play via your smartphone or tablet, you should check this with the online casino beforehand.
WHAT RATINGS DO THE SLOT SITES GET FROM PLAYERS AND EXPERTS?
Finally, if you have found a slots site that you think seems appropriate, it is always a good idea to double-check what others have to say about their experiences there. To do this, you can read reviews from both players and experts.
If the site gets low or mediocre ratings then you should look elsewhere. On the other hand, if a site gets high ratings from both parties as well as meeting other personal requirements, you have probably found the right one.
The list of the best online slots sites above will give you a decent guideline as to which ones are the best. This is because their ratings are based on tests from our experts as well as the opinions of players. The higher the average rating, the higher the level of customer satisfaction.
Sometimes, though, you might want to dig a little deeper. If you have specific preferences, it is usually worth checking how a site performs against those requirements.
HOW WE RATE SLOT SITES

There are hundreds of online gambling sites operating in the UK right now so it is important that you find the perfect one for your needs.
We have reviewed hundreds of slot sites and we do not rank them based on how high their welcome bonuses are. We keep our eyes on each and every casino in order to analyse and then present all of the key features of every individual casino. These include:
- Selection of Online Slots – There are thousands of online slots in the UK, all with varying themes, RTP percentages and ways to win. A slot site can have a huge number of slots in their games library but if the slots are all from the same developers or are hand-picked to be the hardest to win slots, we will swoop in and let you know.
- Bonuses and Promotions – New customer bonuses, loyalty schemes, prizes and raffles, VIP club memberships.
- Bonus Terms and Conditions – Wagering requirements, minimum deposit limit, which payment methods are excluded from bonuses? Is the slots bonus redeemable?
- Site usability, reliability and mobile friendliness – Is the slots site user friendly? Do they look good and run smoothly on hand-held devices? How often does the slot site crash?
- Licensing and Security – Is the UK slot site fully licensed in its respective jurisdiction? What kind of protections are customers given, are there measures in place to protect all players and are the games safe and fair to play?
- Customer Support – How accessible and helpful is the customer support team at the UK slots site? Is there a 24/7 live chat available? Does the site have email support?
- Account Verification Time – How quickly are new accounts verified? Which documents do players need to supply to have their account verified?
- Casino Cashier – Which deposit and withdrawal options does the casino accept?
WHY PLAY ONLINE SLOTS
Online slots allow you to play anywhere with access to an internet connection. This is convenient for many who do not have the time or desire to travel to a land-based casino.
You can also take advantage of better bonuses, a wider range of games and the latest releases. Thanks to the UK Gambling Act, which is controlled and enforced by the UK Gambling Commission, security is high.

TYPES OF SLOT GAMES YOU CAN PLAY ONLINE

Online slot games have grown into arguably the most popular form of casino gambling. Due to their popularity, online slots have become increasingly sophisticated in past years.
Slot aficionados now have a riveting selection of different games to choose from. The games can be divided into different categories. Please find these slot game categories below.
VIDEO SLOTS
Video slots make up the lion’s share of the slot games currently on the market and in the libraries of slot sites. These slots are certainly the most popular variation. Video slots range from 3-reel slots to slots with 5-reels. Most video slots also come with exciting features such as wilds and scatter symbols as well as bonus rounds.
Some of our favourite video slots of 2023 include high RTP slots as well as Gonzo’s Quest, Immortal Romance and Da Vinci Diamonds.
BRANDED SLOTS
A lot of video slots are branded. Branded video slots are amongst the most popular slots online. These slots are based on the likes of movies, video games, television shows, comic books, game shows, sports themes, board games and much, much more.
JACKPOT SLOTS
Jackpot Slots get their name from the jackpots they payout. These slots can eventually payout hundreds of thousands and even millions of pounds.
Top online casinos can generate huge jackpots as a small portion of each player’s stake will contribute to the jackpot. This jackpot will continue rising until one lucky player triggers a win and scoops the lot.
Our favourite jackpot slots consist of Mega Moolah, Wheel of Wishes and Leprechauns Luck.
CLASSIC FRUIT MACHINE SLOTS
These slots mimic the classic slot machines of a bygone area; think pre 2000s Las Vegas and fruit machines in British pubs and arcades! Classic slots feature 3 reels and a single payline in the middle.
Although classic slots have taken a back seat in recent years, these games are designed to appeal to players who enjoy the simplicity of slots rather than the sometimes lairy video slots.
Standout fruit machine slots include Flaming Hot, Jackpot 6000 and Mega Joker. It is worth noting that Mega Joker has one of the highest RTP percentages.
MEGAWAYS SLOTS
Megaways slots were first introduced by Big Time Gaming, but they have let other game developers such as NetEnt, Blueprint Gaming and NextGen Gaming take advantage of their license.
What makes this type of slot unique is the Megaways mechanic. The Megaways engine enables a variable number of symbols on each reel that can produce hundreds of thousands of ways to win.
Today, there are a little over 100 different Megaways slot games that you can play. You can learn more in our article about Megaways slots.
SLOTS SITES SOFTWARE
There are tens of thousands of different games that you can play at different casinos and slots sites. However, did you know that it is not the online casinos themselves who design and develop the games? Casinos get their games from 3rd party casino software providers.
Casinos are willing to pay large sums of money to companies who are able to come up with elaborate and unique slot game titles.
All slots are supplied by software providers. We have listed some of the top online slot software providers below.
NETENT
NetEnt is a Scandanavian software provider and is a company with a huge reputation and a growing popularity. NetEnt are responsible for a number of popular slot games including Gonzo’s Quest, Starburst and Mega Fortune – these three online slots can be played at all of the UK slot sites on this page.
PLAYTECH
Known for producing and developing branded online slots such as Man of Steel and American Dad. Playtech’s most successful slot is Age of the Gods which spawned into a series of multiple slots – all of which come with the opportunity to trigger huge progressive jackpots.
Playtech also owns the gaming company Eyecon which produced the highly popular Fluffy Favourites slot.
Many UK casinos and slot sites will feature online slots provided by PlayTech.
MICROGAMING
Microgaming is an extremely well-known online slots provider which produces top UK slots games. They can lay claim to hundreds of online slots titles. Slots developed by Microgaming are amongst the most popular and are available at almost all UK slot sites.
Branded slots like Jurassic Park and Game of Thrones are Microgaming products but it is their jackpot slots which likely rank as their best slots. Mega Moolah is a hugely popular slot whilst Immortal Romance slot ranks as one of the best payout slots available to be played.
BIG TIME GAMING
Big Time Gaming is most widely associated with creating the Megaways slot mechanic. This mechanic is implemented in Megaways video slots and allows players many, many more ways in which to win – sometimes over 100,000.
Due to the increasing popularity of Megaways slot games, Big Time Gaming is now an in-demand slot developer at many UK slot sites.
PLAY’N GO
Another Scandinavian brand, Play N’ Go has been operating within the online slots niche since 2007. The company’s standout feature in their slots is the always high RTP rate.
In addition, Play N’ Go look to arm their slot games with narratives. Players get to follow an exciting story line as they play through the slot. Once the story is completed, you are then often treated to a bonus round and other exciting features.
Popular slots from this brand include Book of Dead, Legacy of Egypt and Rise of Olympus.
IGT
IGT is a slot software provider specialising in themed and branded slots. This developer is one of the oldest slot developers and has a huge amount of influence in both the online and offline casino world. IGT created many of the top slots that you will encounter if you visit a brick and mortar casino.
As for the online slot’s world, IGT are serial online slot developers and you will encounter IGT slots at all of the best online slots UK sites. From a user perspective, IGT often goes about updating and refreshing a lot of their older slot games which is rare. Most software providers prefer to develop brand new games rather than improve their older slots.
Popular IGT slots include Da Vinci Diamonds and Family Guy. You can play both of these games at most slot sites.
BLUEPRINT GAMING
Blueprint has begun to take advantage of the BTG Megaways mechanic and are developing games featuring this mechanic. Some of their successes so far include Genie Jackpots Megaways and TED Megaways.
PLAY SAFELY AND RESPONSIBLY
Regardless of which slot site you choose, we cannot stress enough how important it is that you play in a safe and responsible manner. Online slots should be no more than a fun side activity enjoyed for a short time. Due to the nature of slots, the casino always has the advantage and they will therefore win in the long run. Although you might win sometimes, you are more likely to lose money. As such, you should never treat slots as a way to make money or to escape from boredom or other problems.
We always recommend that you set clear limits before playing. UK licensed slot sites are required to supply tools to help all players with this. For example, you can set time limits, spending limits and deposit limits.
The Gambling Commission has also compiled guides on how you can stay safe when gambling. Additionally, there are several organisations and charities that can provide extra support and help if you need it:
- Safer Gambling Week – An industry initiative to promote safer gambling in the UK and Ireland. On their website you can access informative articles about how you can play more safely along with gambling tools to help you stay in control.
- GamCare – The UK’s leading provider of support and advice for anyone affected by problem gambling.
- BeGambleAware – Charity offering free and confidential help for those concerned about their own or someone else’s gambling.
It is worth mentioning that the slot sites themselves have an obligation towards responsible gambling. You can take temporary breaks or even shut down your account permanently if you feel that you are playing too much. You can do this yourself or ask the support to do it for you. Ultimately, however, we recommend that you stop playing if you are no longer having fun. If you are unable to do so yourself, you should seek help immediately.
FAQS
The best sites for winning are those that have online slots with high RTP.’s Such sites include Skol Casino, All British Casino and Monopoly Casino. The online slots that give you the highest chance of winning at these sites are usually video slots and a few jackpot slots.
2. Are UK slot sites safe to play at?
No, not all slot sites in the UK are safe for you to play at. However, the slot sites listed at SlotsHawk are 100% safe and fair. All the casinos we list have been thoroughly reviewed by not only us but also the UK Gambling Commission. If you are unsure whether a UK slot site is safe, scroll to the bottom and look out for the UKGC stamp of approval.
3. Which slot site has the best odds?
Slots odds are not fixed. They are determined by their Return To Player (RTP) percentage which shows how much money will be paid back compared to the amount wagered. For example, a slot with 94% RTP will, on average, pay back £94 for every £100 wagered. This is of course theoretical and will change from session to session. If you are looking for a slot site with the best odds, you should find the games with the highest RTP’s and head over to an online casino that has the game.
4. Can you win money playing online slots?
Yes, it is possible to win real money playing at licensed UK online casinos, but this means that you can also lose money. Most slots give players the chance to play for as little as 10p per spin up to £100 per spin. For example, if you deposit £50 and you spin the reels on a slot and win £25 from a £1 spin, you will be able to withdraw your winnings back onto your debit card or other payment method you deposited with.
5. Can I play slots online for free?
It is possible to play slots for free, but you will first need to register at an online casino that is able to offer free-to-play slot games. In May 2019, the UKGC ruled that you had to be registered to an online casino before you could be allowed to play any form of slot games online. This ruling came into place to ensure that under 18s were prevented from experiencing slot play. Anyone registering to an online casino will have their age verified.
6. What kind of slot has the biggest wins?
Progressive jackpot slots have the largest potential wins. Top slot sites can generate huge jackpots as a small portion of each player’s stake will contribute to the jackpot. This jackpot will continue rising until one lucky player triggers a win and scoops the lot. Progressive jackpot slots can payout jackpots of over £1 million.
7. Where can I play progressive jackpot slots?
Progressive jackpot slots are available at most online casinos. Some of them award small prizes and are triggered weekly whilst others have huge prizes which pay out rarely but when they do the jackpots can be life changing sums. We recommend Mega Moolah; this is one of the most popular progressive jackpot slots to play in the UK.
8. Can I play online slots on my mobile?
Over 50% of slot players play via their mobile phone. HTML5 technology is used by game developers which ensures that their products are optimised for all devices. Slots casinos are now developed for mobile first. Developers and software providers will first work to ensure their game is fully optimised for a mobile device.
