Last Updated: February 14, 2025

Written by Jean Prince

Discover slot sites and online slots that are available in the UK as of February 2025. All of the online slots sites on this page have been tested and reviewed by the team here at SlotsHawk.

A slot site is a website which offers the opportunity for visitors to play an array of slot games. Today, there are a countless number of slot sites available. Most of these sites allow you to choose from hundreds of different online slots. However, the quality between the sites can differ greatly, so your choice of site will have a big impact on your slots experience. We will help you navigate this selection so that you can find some great slot sites to play at.

Below, you can find our list of the best UK slot sites based on factors such as user experience, game selection, bonuses, RTP and payouts. Following the list, you can find more detailed reviews of the top 10 sites. We will also cover some of the best options based on player preference as well as some tips on what to consider when playing slots.

BEST SLOT SITES UK – FEBRUARY 2025

TOP 10 SLOT SITES – IN DETAIL

These are SlotsHawk’s hand-picked recommendations of the top 10 slot sites in the UK based on our specific review criteria. They are all excellent in their own ways and they all come with a great selection of slot games, varied welcome bonuses and good customer support etc.

In essence, these are the best slot sites for winning and having an enjoyable experience.

1. CASUMO

The best slot site as decided by UK punters and SlotsHawk is Casumo. The reasons? First of all, Casumo is one of the oldest (experienced) slot sites and has therefore stood the test of time. Secondly, Casumo has over 3,000 different casino games, making their games library one of the biggest.

Casumo has recently undergone a face lift making their site more attractive than ever. Another reason why the SlotsHawk team rates Casumo as the top online slot site is due to the daily casino promotions. Every Tuesday, Wednesday and Thursday of the week, you are treated to free spins, whilst other days of the week have their own special promotions too. According to Casumo themselves, they hand out an average of 7,400 rewards per day. Loyalty programmes are a key component when we review slot sites as we know that they are a big part of the all-round experience for players.

2. 10BET

10bet is a new addition to our list of the top UK slot sites but it goes straight to number two thanks to its modern feel and excellent choice of games. We are also pleased to say that 10bet has its own app and you will receive a free £10 bet when you bet £50 or more via the 10bet app.

The only real negative aspect of 10bet is that it does lack some popular slots titles. However, if you can get past that then you will be onto a winner in our opinion. Just remember to search for the slot you want to play before you sign up so that you can be 100% sure they have it in their games library.

3. PLAYOJO

You may have seen adverts on your TV for PlayOJO, (especially if you ever watch the Challenge channel) it is certainly one of the most well-known slot sites in the UK. Dubbed as the ‘fair casino’ PlayOJO receives numerous industry awards and bonus winnings can be withdrawn in cash as there are no wagering requirements, ever.

Add to the fact that you can play more than 3,000 online slots, a dedicated casino app and fast withdrawals, and you will quickly realise that the popularity of PlayOJO has been well-earned. Like all good slot sites, daily promotions are available too and we would like to reiterate that there are never wagering requirements on bonuses at PlayOJO.

4. HYPER CASINO

We describe Hyper as the most energetic casino and it is one of several ‘White Label’ casino sites. These sites are those which are built and operated by a company and then sold to entrepreneurs who can add their own stamp to the casino. White label casinos all have the same games and payment information – the only real difference from one White Label casino to the other is the theme.

SlotsHawk believes Hyper to be the best White Label casino. Why? First of all, it is extremely well-run by L and L Europe. Secondly, the UX (user experience) and on-page navigation is the best out of all the White Label operators, in our opinion. Another advantage all White label casinos have is the large number of deposit and withdrawal methods they make available.

5. GRAND IVY

With over 2,000 slots available, the classy Grand Ivy Casino slots library appeals to most slots aficionados, especially given that there are games from many of the top slot providers including NetEnt, Red Tiger and IGT. In addition, Grand Ivy promotions include weekly cash giveaways, as well as yearly cash prizes of £30,000 – all of which are free of wagering requirements.

There are plenty of different types of slots at the Grand Ivy too including high RTP and other big win games such as Book of 99. A mobile app is available too which makes playing on-the-go much easier. The site might look a little bit old-fashioned these days, but it works very well.

6. MRQ

For any avid sports viewers, you will be well-aware of the presence MrQ has had in the UK over the past few years. The MrQ casino logo is now one of the most recognisable in the country whilst SlotsHawk regards MrQ as one of the top slot sites due to the bright and welcoming theme, easy user navigation and supreme collection of online casino games and slots.

MrQ is a great choice if you are searching for welcome bonuses as they are all uncapped with any wins credited to your real money account balance. MrQ describes itself as having super-fast withdrawals. Like with most fast-payout slot sites, MrQ usually guarantees that withdrawals will be in your bank account within 24 hours. Other features of MrQ include over 900 slot games as well as a live casino and Bingo lobby.

7. LUCKSTER

The Irish are a common symbol for luck which is probably why Luckster has an Irish theme for their slot site. The luck of the Irish is based on things like four leaf clovers and lucky leprechaun’s. Of course, these are all just superstitions but regardless, Luckster is a great looking online casino which is operated by Aspire Global – a company based in Israel which operates dozens of different UKGC licensed slots sites.

Luckster is probably, out of all the slot sites on this page, the least well-known, but we expect that to change soon as more of you come to understand how good Luckster is. Real money slots at Luckster include plenty of Megaways slots as well as the usual jackpot games. The downside to Luckster is the lack of daily promotions, but if you are on the lookout for those then there are plenty of other options for you on this page.

8. SKOL CASINO

We love Skol Casino. It has been around for several years now and has over 2,500 games from some of the best studios around including Microgaming, Red Tiger and Play N’ Go. Like most of the top sites, Skol has daily offers for loyal players which consist of free spins, deposit bonuses and reload bonuses. In fact, Skol has 50% matched deposit bonuses every Friday, Saturday and Sunday.

We are positive that you will find a game to enjoy at Skol Casino too. There are plenty of options including Megaways slots as well as high and low volatility games with high payouts. The only reason Skol does not appear higher on our list is due to the fact that they do not concentrate as much on the UK market as they did in the past.

9. BET GROUSE CASINO

We are always on the lookout for standout new slot sites and BetGrouse is one of the top ones launched in this year. The reasons? First of all, it has a great colour scheme which is very easy on the eye. There are plenty of slot sites which are owned by companies which do not appear to care about aesthetics, but this is certainly not one of those. In addition, this slot site has a comprehensive loyalty rewards programme. The more you play, the higher you will rank and you will receive achievement badges – not many other slot sites offer this type of gamification.

As far as slots are concerned, there are games from over 50 different providers, including both well-known developers and lesser known ones – this is great news as offering games from a long list of providers shows signs of a healthy online slot site.

10. PLAYZEE

Another top drawer White Hat Gaming slot site, Playzee is a fun and friendly operator specialising in online slots of all shapes and sizes. Like the aforementioned Bet Grouse Casino, Playzee has its own loyalty rewards programme too in the form of ‘Zee points’. These work in a similar way to other loyalty rewards whereby if you complete tasks (play certain slots, make deposits etc) you will gain points which you can then spend in the store.

Playzee Casino has an experienced setup behind it having operated within the UK gambling sector for many years now. They also have two sister slot sites in Spinyoo and BZeeBet. SlotsHawk are a big fan of the sheer number of games available at Playzee too with over 2,000 playable slots.

HOW SLOTSHAWK REVIEW, COMPARE AND RATE THE TOP SLOT SITES

Passion, energy and doing right by our readers is at the heart of everything we do at SlotsHawk and we take our slot site reviews very seriously. Of course, we want to share our own experiences with you, but unlike other similar sites to ours, we prefer to go further than that to help you.

Therefore, our team of reviewers assess all slot sites objectively based on a set list of criteria. We score each slot site a score out of 5. We always explain all of our decisions directly so that you can be in no doubt as to why we regard certain slot sites as superior to others.

CRITERIA WE USE WHEN ASSESSING AND EVALUATING SLOT SITES

THEME, USER EXPERIENCE AND NAVIGATION

One of the key factors which helps to differentiate slot sites from each other is the design theme. Some sites spend a lot more time on creating an outstanding theme than others, and the SlotsHawk reviewers consider a beautiful theme an important component of a top of the range slot site – nobody wants to play at an ugly slot site after all.

Mixed into a slot sites design is the user experience and how easy a site is for its users to navigate. User experience is obviously important for both the user and the slot site itself. If players are struggling to find what they are looking for at a slot site, then it is likely they will go and play elsewhere (there are no shortages of online slot sites). Therefore, any slot site worth its salt will ensure that their players have a good user experience.

Navigation is an aspect of user experience and concerns how easy it is for users to get from one part of a slot site to the other. The best ones will ensure that navigation is seamless and that all the important parts of a slot site are simple to find.

GAMES, SOFTWARE AND PLATFORM

When we are confident that a site’s design is top notch, we delve a bit deeper into the platform itself, this consists of the software the slot site uses and, of course, the games they have available to their users. It should go without saying, but just because a slot site looks good does not mean it plays well. Some sites can look truly beautiful, but they can also be crawling with bugs and lag – outside appearance can often hide an ugly inside after all.

As far as games are concerned, some sites prefer to make available as many slots from as many different slots providers as possible, whilst others tend to pick the hottest slots of the moment. Regardless, we only recommend slot sites with the best slots available. Our aim is to recommend sites which you will enjoy playing at and return to in the future.

BONUSES, PROMOTIONS AND LOYALTY PROGRAMMES

All slot sites will incentivise new players with welcome bonuses, but the ones at the top will have built-in loyalty programmes which reward their players with daily promotions. The best loyalty programmes use gamification in order to make levelling up more exciting. Additionally, they will also reward players with points which can be spent on different rewards of the user’s choice.

SlotsHawk looks at whether or not the promotions offered by slot sites offer any real value and whether those rewards are achievable. We always take a deep look into the terms and conditions of the bonuses in order to see whether what they are offering is fair.

SECURTIY, SAFETY AND LICENSING

As we have already mentioned, we only review slot sites licensed by the United Kingdom Gambling Commission. This means that every slot site on SlotsHawk will ensure that all appropriate verification, responsible gambling and security measures are in place.

Any slot site which proves to be unsafe or unethical will miss out on a SlotsHawk rating and review. To reiterate, we only review sites which meet our high expectations.

CUSTOMER SUPPORT

All of us SlotsHawk reviewers are slots players ourselves, so we know that when something goes wrong (which it inevitably will) we want to receive support. The customer support options available are therefore another key factor when we review slot sites. We look at whether there is 24/7 support or not. A slot site offering a 24/7 live chat option with a real human-being will ensure that it will receive a higher review score.

A slot site which is easily contactable and open to their customers is a strong indicator of an excellent slot site.

BANKING OPTIONS, DEPOSIT AND WITHDRAWAL SPEEDS

It is important for any trustworthy slot website to ensure that they offer their customers a wide number of deposit and withdrawal options. We will look into all payment options available as well as any transaction fees and the processing times. Low minimum withdrawal limits and fast withdrawal speeds will ensure a higher review rating. High fees and slow processing times means a lower review.

In our reviews, we clearly indicate the minimum withdrawal fees, as we know from experience how important this is to players.

THE SLOTSHAWK WRITERS RECOMMENDED SLOT SITES

Although we have already divulged our top 10 slot sites, that list was based solely on specific set criteria. Think of it like the FIFA World rankings – the top 10 teams are all excellent but are evaluated on their performances over a set period of time.

Our writers recommendation list is different and reflects our writers personal feelings on what characterises the best slot sites. We also consider feedback from players. At this point, we have recommended slot sites to thousands of UK gamblers and many of them have contacted us to let us know about the slot sites they have played at.

You may even come across a hidden gem in this selection.

1. SKOL CASINO

Since SlotsHawk first went live four years ago, Skol Casino has been the most popular slot site among our readers. Every aspect of Skol is well-above average, from its daily promotions and excellent user experience to the slots on offer. Everything about the site is friendly and welcoming. The theme is smooth and simple with a clean white giving it a modern look.

What makes Skol Casino special according to our writers:

• Daily promotions and loyalty rewards.
• Sleek and modern theme.
• Easy navigation across the site.
• Fast withdrawals.
• £20 minimum withdrawals.
• Easy to search by game type. It is also possible to search by developer.
• Search feature gives the jackpot slots which are most likely to be triggered.
• Promotions include Tuesday Tails and Wacky Wednesdays where you can play with extra cash.

2. ALL BRITISH CASINO

An online slot site built specifically for British players, All British Casino was one of the first slots sites we reviewed at SlotsHawk and despite its relatively old age, it remains one of our favourites. Since we first reviewed All British Casino, the site has undergone a brand-new design as well as a logo change, which has only improved the experience for players. All British Casino use a White Label platform, which makes it a bit restrictive, but it is nonetheless a very well run site.

All British Casino is the favourite casino of our writer Yvonne Greenwood due to the following reasons:

• Caters to UK players only so players from the UK are treated as VIPs.
• The site is regularly updated both with new features and new slots and will continue to operate in the UK for the foreseeable future.
• Slots from A-list developers including NetEnt, NoLimit City, Push Gaming, Thunderkick and Relax Gaming.
• Daily rewards and 10% cashback on all losses at the end of each month.
• No charge for deposits or withdrawals.

3. BALLY CASINO

A newer slot site, Bally Casino is quite a small platform in comparison to some of the others at SlotsHawk, but it has one of the best welcome bonuses for new UK players and that is the reason why we like it so much. Bally initially only had a small games library, but it has evolved nicely and now possesses over 600 different slot games as well as a live casino lobby. Operated by Gamesys, Bally is one of several slot sites from Gamesys.

According to our writers, Bally Casino is a fine slot site because:

• All bonuses have zero wagering requirements.
• New site with plenty of new slots.
• Easy navigation.
• Lots of free spins for loyal players (all without wagering).
• £10 minimum deposit.
• Simple navigation.

4. NO BONUS CASINO

No Bonus Casino has made a bit of a comeback lately, and it is one of Jean Prince’s favourites right now. It is one of the oldest UK slot sites, but you could not tell as the site has gotten a nice face lift with a new design, making it look as good as any other modern site. Contrary to its name, we actually think that No Bonus Casino has one of the best bonuses. The daily cashback bonus offers better value than 99% of the bonuses currently available as it comes with zero wagering requirements.

Why Jean Prince loves No Bonus Casino:

• 10% daily cashback – no strings attached.
• More than 800 slots in all different game categories: video slots, classic slots, jackpots, Megaways and Slingo.
• Multiple slots with high RTP rates between 97-99%.
• Fast withdrawals with no fees.

5. CASUMO

All of us writers at SlotsHawk have an account at Casumo for a number of reasons. Firstly, they have been in the slot sites business for a number of years now and are one of the most experienced in the UK. Secondly, Casumo has amassed an unbeatable number of slot games – their selection of Jackpot slots in particular is second to none. Casumo has recently gotten a new management team too and we have been informed that the new management will create a new rewards programme for their players.

Casumo is one of SlotsHawk’s favourite slot sites:

• One of the top UK slot sites for over a decade.
• Daily promotions.
• Over 3,000 slot games.
• Access to all of the best and most popular slots developers including Wazdan, Big Time Gaming, Microgaming, Playtech and Blueprint.

BEST SLOT SITES BY CATEGORY

Each player have different preferences when playing slots. So, the best slot site for one player may not be the ideal site for someone else. Below, we have listed the best online slot sites for some of the most popular categories – game variety, RTP, new slots, Megaways, jackpots, fastest payouts, free spins and more.

BEST SLOT SITE FOR GAME VARIETY: VIDEOSLOTS

Not only does Videoslots claim to possess every single online slot game, but it also has a live casino lobby as well as its own dedicated sports betting platform. Videoslots Casino has several thousand slots so it will be pretty much impossible for you to become bored with their slots variety.

• More than 8,000 casino games including the biggest library of slots in the UK.
• All the different types of slots – classic slots, video slots, progressive jackpots, Megaways and Slingo.
• Battle of the slots tournament means players can receive random rewards for playing slots.
• The Clash of Spins programme can earn players different rewards.
• Weekend Booster – 0.5% of your winnings are transferred to a ‘vault’ and however much is accumulated is paid to you on the next Friday. You can opt out of this if needed.
• Desktop and mobile versions are both designed with the user in mind and navigation across the site is excellent.

BEST SLOT SITE FOR HIGH RTP: MRQ

Unfortunately, it has become common practice among UK slot sites to lower the RTP on slots where developers allow them to. One of the few sites that has gone against this trend is MrQ. They still have the highest RTP setting for almost all of the slots in their library.

In addition, it is also possible to play several slots with some of the best RTP percentages on the market, including 1429 Uncharted Seas (98.60%), Money Cart 2 (98%) and Wild Swarm (97.03%).

• High RTP rates across the board.
• Slot games with 97%+ RTP.
• Over 900 slots in total.
• Well-known and trusted brand.
• Welcome bonus includes free spins on one of the best slot games around in Big Bass Secrets of the Golden Lake.

BEST SLOT SITE FOR NEW SLOTS: CASUMO

Hundreds of new slots are released on a monthly basis and with the expertise of some slot developers, slots are getting better and better with each passing year. The SlotsHawk reviewers love reviewing new slot games and we are fully aware how many players also love playing the newest online slots around.

The Casumo Casino slots catalogue is updated on a weekly basis. Due to the fact that Casumo works with over 100 different developers, it means that they have access to a huge number of new slots.

• New slots are added weekly.
• Has been voted UK casino of the year numerous times.
• Huge library of over 3,000 casino games.
• Loyalty rewards programme.
• Has a downloadable app for mobile gameplay.

BEST SLOT SITE FOR MEGAWAYS SLOTS: PLAYOJO

In 2016, Big Time Gaming introduced their Megaways mechanic which ended up changing online slots forever. Megaways increased the number of paylines (ways to win) up to 117,649. Fast-forward to 2025 and there are now hundreds of Megaways slots from a variety of slot developers.

Some of the best Megaways slots include Rasputin Megaways, Anubis Wild Megaways and Medusa Megaways, and all of them can be played at PlayOJO Casino. They are therefore our go-to choice for Megaways slots. Aside from Megaways, PlayOJO has a huge variety of other popular games including jackpot slots, Monopoly games and live dealer games. There is also a loyalty scheme which awards those of you who love to play frequently.

• Over 100 of the best Megaways slot titles.
• OJO rewards system is one of the best loyalty schemes around and offers more value than most other sites.
• Welcome bonuses don’t have wagering requirements and therefore represent good value.

BEST SLOT SITE FOR JACKPOTS: SKOL CASINO

Jackpot slots are behind the biggest casino payouts of all time. Progressive jackpot slots like Mega Moolah and WowPot have created record-breaking spins of over £10,000,000 on multiple occasions.

While most slot sites have at least a handful of jackpot slots in their selection, not all of them have the two mentioned above, which are by far the best ones due to their payout potential. Of course, there are more great jackpot options in 2025 like the Dream Drop Jackpot series from Relax Gaming.

Skol Casino has been one of our favourite slot sites for years, and they offer all of these three jackpot slots, so it will have to be our number one choice. Another great option is All British Casino. While they don’t have the Dream Drop series, they instead have the classic Mega Fortune from NetEnt.

• Large variety of progressive jackpot slots, including Mega Moolah, WowPot and Dream Drop.
• Search feature gives the jackpot slots which are most likely to be triggered.
• 2,500+ casino games from both well-known and lesser known developers.
• Daily promotions and loyalty rewards.

BEST SLOT SITE FOR FAST PAYOUTS: YETI CASINO

Withdrawal times are an important aspect of a slot site and it’s a key detail we look at when reviewing any slot site. Any slot site which can process withdrawal times quickly and with zero fees usually gets rated highly by the SlotsHawk review team and are known as fast withdrawal slot sites. The slot site which scores best for this is Yeti Casino.

Whilst the average time between asking a slot site for a withdrawal and the money landing in your account is within 24 hours, Yeti Casino are able to process fast turnarounds of just one hour. Of course, it is not only up to the casino to process withdrawals, they are also reliant on you completing and verification processes, so the quicker you do this, the faster your payout. The first time you make a withdrawal will usually be the slowest, but after you’ve got all of the processes out of the way, you are free to make withdrawals here, there and everywhere.

• Withdrawals are processed within an hour.
• Payouts are available via Visa, Mastercard, PayPal, Skrill, Neteller, Apple Pay, Trustly and bank transfers.
• Over 3,000 slots available.

BEST SLOT SITE WITH NO WAGERING FREE SPINS: BETFRED

One of the major downsides with many slot bonuses is the high wagering requirements. You usually have to play through wagering requirements as high as 35-50x the bonus before you can cash out the bonus funds. This is not the case with no wagering free spins. Instead, you just have to use your free spins, and any funds remaining once the free spins have been used are yours to keep. This makes no wagering free spins one of the bonus types with the highest overall player value. For this reason, this is our favourite bonus type at SlotsHawk.

Today, more and more slot sites are offering no wagering free spins as part of their welcome bonus, but BetFred stands out from the pack here. They give you more wager free spins than any other UK slot site, up to 200 depending on which bonus you claim. You can choose between the following three bonuses when making your first deposit:

• 50 wager free spins on Age of the Gods at £0.20 per spin.
• 100 wager free spins on Better Wilds at £0.10 per spin.
• 200 wager free spins on Age of the Gods: Gods of Storms 2 at £0.05 per spin.

BEST NEW SLOT SITE: PUB CASINO

Launched in 2023, Pub Casino is one of our favourite new slot sites. Here you can play plenty of the top-rated online slots such as Big Bass Bonanza, Punk Rocker and Genie Jackpots Megaways. In addition, you will also find the full collection of Fluffy Favourites slots.

There are thousands of games on the site including both online slots and classic casino games such as Roulette and Blackjack. Having been launched less than two years ago, Pub Casino is a very user-friendly site and also has its own downloadable app:

• Launched in 2023 and built for British players.
• Excellent collection of the most popular slots.
• User friendly with 24/7 customer support.
• Plenty of withdrawal and deposit methods.

MOBILE SLOT SITES

Most of us have a mobile phone these days and with excellent internet connection available whilst on the go, it should come as no surprise that the majority of the top slot sites can also be played on a mobile device. However, when it comes to the best slots sites, not only do they need to be trustable, they must also be mobile-friendly.

CONVENIENCE OF PLAYING SLOTS ON YOUR MOBILE

According to the SlotsHawk statisticians, more than half of online slots players are playing via their mobile phone. There are plenty of benefits of playing at mobile slot sites:

• Quicker – If a slot site has its own app, accessing your favourite slots has never been easier. It is possible to play 100% of slot sites casino games on your mobile.
• Payments – Making deposits and withdrawals is easier than ever, especially if you set it up using a finger ID on our mobile.
• Promotions – Many slot sites now offer promotions specifically for those who play with their mobile.
• Ease of access – It is simple to play when you’re on the move. You could be on the train, the bus or in the back of a taxi.
• No downloads – It is possible to play at slot sites directly in your mobile phones browser.

MOBILE APPS VERSUS MOBILE WEBSITES

Ask 10 people and at least eight of them will tell you that they play on their mobile. Out of those eight people, at least six of them will probably play via a slot site app. Almost all slot sites have their own downloadable app now and slots developers create and design their slots to be played on a mobile phone.

Not all slots are available on a mobile though, older slots in particular have not always been able to be optimised for mobiles, so these ones can only be played on a desktop or laptop. Overall, the majority of online slots will be able to be accessed.

THREE OF THE UK’S MOST MOBILE FRIENDLY SLOT SITES

1. BETFRED

Betfred is one of the most well-known names when it comes to slot sites in the UK. They have been a high street bookie for a long time now and there are still plenty dotted around UK high-streets. Betfred is now one of the biggest slot sites around, albeit their collection of slots is not quite as good as some of the others on SlotsHawk.

BetFred has its own slots app too and you can take advantage of their welcome bonus which includes free spins with no wagering requirements. Betfred has earned its reputation as one of the most player-friendly slot sites:

• Bonuses consist of no wagering requirements.
• Well-known brand.
• Safe and secure.
• Live casino lobby.
• Downloadable app.
• Unique mix of online slots.
• BetFred offers a state-of-the-art mobile casino experience.

2. VIRGIN GAMES

Another big brand slot site, Virgin Games makes the most out of its worldwide brand name and needs little introduction. The team at Virgin Games understands how important it is for their players to have a smooth mobile casino experience which is why they offer one of the best apps around. They are also focussed on meeting the expectations of their players, which means they focus on table games, online slots, poker and live dealer games.

Virgin Games is operated by Gamesys which means whenever a new player stakes their first £10, they will receive wager free spins on the Double Bubble slot, making Virgin Games one of our favourite Double Bubble sites too.

• Well-known brand.
• All games use HTML-5 technology.
• Downloadable app optimised for iOS and Android.
• Works well on mobile browsers.
• Site is separated into casino games, slots and live casino making navigation easy.

3. MRQ

MrQ have been the main sponsors of plenty of recent UK sporting events and are now a hugely recognisable online gambling brand. Launched in 2018, MrQ now offers over 900 carefully chosen online slots. The site itself is very minimalist which makes it simple to navigate around. MrQ has its own bespoke platform too, so it is one-of-a-kind.

There is not much difference between the desktop and mobile site and MrQ has its own app too. The key factors of MrQ are:

• Fantastic mobile games from the likes of Red Tiger, Thunderkick, Big Time Gaming, Peter and Sons, Relax Gaming, Push Gaming and plenty more.
• Downloadable app for iOS devices.
• Weekend ‘Happy Hours’ makes playing on a weekend more profitable.
• New games added on a weekly basis.

HOW TO REGISTER AT A SLOT SITE

The process of actually signing up/registering at a slot site is straightforward. Four things you will definitely need are:

• Email address.
• Identity document proving you are who you say you are.
• A proof of address dated within the last three months.
• A valid mobile phone number.

The process is straightforward if you have all of the above readily available.

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. Most video slots come with exciting features such as wilds and scatter symbols as well as bonus rounds.

Some of our favourite video slots of 2025 include high RTP slots as well as Starburst, Immortal Romance and Razor Returns.

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 pay out. These slots can eventually pay out 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 pot. Our favourite jackpot slots consist of Mega Moolah, WowPot and Dream Drop.

CLASSIC FRUIT MACHINE SLOTS

These slots mimic the classic slot machines of a bygone era; 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 (99%) of all UK online slots.

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.

SLINGO SLOTS

Slingo is a mix between slots and bingo. This unique game concept was first developed back in 1994 by David Lyons and Sal Falciglia, but after securing a license, the British company Gaming Realms has become the main developer of Slingo games. Today, you can find over 30 of such games. Some of our favourites include Slingo All British, Slingo Starburst and Slingo Fortunes.

While Slingo is not yet available at every UK slot site, the vast majority of the top-rated sites have it in their game selection. We can recommend All British Casino and Slingo Casino as they both have a large selection of Slingo slots. For more options, see our Slingo sites article.

BEST ONLINE SLOTS AND WHERE TO PLAY THEM

Now you’ve got the low-down on which is the best slot site for you, you will want to know which are the best online slots to play in the UK. The number of slot games online run into the tens of thousands and they vary dramatically in quality, theme and general playability. The online slots you will love will depend a lot on your personal preferences and this includes not only the themes, which can range from space all the way to underwater, but also on which features you enjoy the most. Modern slot features include the likes of cascading reels and special symbols.

With that being said, if you are looking for some excellent slot games, which include the likes of Megaways slots, jackpot slots and low and high volatility slots, below are the top 10 online slots.

1. DRAGON’S MYTH (MICROGAMING)

RTP: 96.01%
Maximum payout: 2,000x your bet
Ways to win: 20
Volatility: Low
Theme: Fantasy

An easy to play slot with bags of character, Dragon’s Myth is played on a simple 5×3 grid with 20 paylines. Released in 2015, this is an older slot but it remains popular in 2025 due to its top notch graphics and multipliers which can rise up to 2,000x the wager.

2. BONANZA MEGAWAYS (BIG TIME GAMING)

RTP: 96.00%
Maximum payout: 26,000x your bet
Ways to win: 117,649
Volatility: High
Theme: Mining

The first ever Megaways slot and in our opinion the best of all Megaways slots, Bonanza Megaways was the first game to feature the cascading reels feature which opens up the possibility for unlimited wins and that is the reason why Bonanza Megaways is one of the top online slots ever. Bonanza Megaways is also the first slot to have 117,649 paylines due to the unique Megaways game mechanic. Look out for the diamond symbols which are the highest paying. Top payouts can reach 26,000x the bet.

3. RAZOR RETURNS (PUSH GAMING)

RTP: 96.55%
Maximum payout: 100,000x your bet
Ways to win: 40

Theme: Ocean/Sea

Underwater theme slots have been popular for a number of years now as they usually are filled with fun components such as mystery symbol payouts, mystery symbols and nudge and reveal features. Razor Returns is the sequel to the equally splendid Razor Shark, but with the return, Push Gaming gave us a lot more in terms of juicy features. The slot is played on five reels and five rows with 40 paylines and can be played by both high rollers and low limit players due to its min/max bet limit per spin of 10p/£100.

RTP: 96.09%
Maximum payout: 500x your bet
Ways to win: 10
Volatility: Low
Theme: Space

Starburst can be played at probably 99% of online slot sites and it is probably the most well-known online slot of all time. Exactly why it became the most popular we are not totally sure, the best aspect of Starburst is how easy it is to play, there are no fancy mechanics or complex features. There are plenty of slot sites that use Starburst as the slot for the free spins they offer to players as welcome bonuses. If you are a slots player, it is likely that you will have played Starburst at least once in your life.

RTP: 96.08%
Maximum payout: 300,000x your bet
Ways to win: 108

High volatility mixed together with huge potential payouts – perhaps unsurprisingly, Tombstone RIP has been a big hit for NoLimit City since it was first released in 2022. It uses plenty of slot features including xNudge, xSplit and xWilds. There are also two different free spins rounds where multipliers can go up to 999x. The high volatility aspect means that you will only win on an average of 9% of spins, but the rewards potential makes that worthwhile for a lot of players.

Play at: PlayOJO

8. JACK HAMMER 2 (NETENT)

RTP: 97.10%

Jack Hammer is a comic book superhero and the main character of the slot. There are now three slots in the Jack Hammer series with the most recent one released in 2024.

TOP TIPS FOR PLAYING AT SLOT SITES

Whether or not you are new to the online slot scene, it literally pays to arm yourself with as much information as possible. Although the primary reason for playing slots is to have fun, it’s even better when you manage to hit some big wins. There are ways that you can increase your chances of hitting wins, even though online slots are entirely luck based.

Ready to play the very best online slots? Before you begin, it is useful to understand exactly how slot sites work, the differences between them and what separates a good slot site from a poor one. Once you have armed yourself with this information, you can make a clear and informed decision on where the best place to play is depending on exactly what you are looking for. If you are still not 100% sure what you are looking for, keep reading to find out what makes slot sites different from one another.

SLOT DEVELOPERS PREFERENCE

Some players prefer to play slots by certain developers. There are over 100 different slot developers but there are twenty or so which are considered to create world-class online slots. The most popular developers include NetEnt and Playtech but other popular choices include:

• Red Tiger Gaming
• Relax Gaming
• Thunderkick
• Push Gaming
• Playbro
• Big Time Gaming
• Playtech
• Blueprint Gaming
• NoLimit City
• Pragmatic Play

Some more developers who may be lesser known include the following who have created some excellent slots:

• Yggdrasil – The developer creating the slots with the best-quality graphics.
• Peter and Sons – Historically themed slots.
• Wazdan – Choose your own volatility level on all of their slots.

SLOT SITE BONUSES AND PROMOTIONS

A key component of any slot site is the slots bonuses they offer to their players. Now, although pretty much all slot sites will offer new players welcome bonuses, it is the bonuses for loyal players which you should pay most attention to. When choosing a place to play slots, we recommend a slot site with daily promotions for their loyal players. A slot site which only rewards new players for signing up and not their loyal players is one to avoid.

Two slot sites we can recommend for their loyalty programmers and promotions are No Bonus Casino and PlayOJO. First of all, No Bonus Casino saves all of their rewards and goodies for their loyal players – they do not offer any sign-up/welcome bonuses. In our opinion, this is a good sign that the team behind the casino is confident that their product is so good, they do not need to offer incentives for players to sign up. PlayOJO on the other hand has both an excellent welcome bonus and a top-quality loyalty scheme known as OJO Rewards. Both of these sites regularly hand out rewards and freebies just for being members.

HOW TO CLAIM A SLOT SITE BONUS

For those of you who are ready to sign-up to one of our recommended slot sites and claim a welcome bonus, you can get started following the steps below:

1. Choose the site which appeals to you most from our recommended list.
2. Sign-up and complete the full verification process to get access to your account.
3. Make a deposit in order to take advantage of any welcome bonus. (Make sure you read the terms and conditions of said bonus before you deposit.)
4. Wait for the bonus to enter your account.
5. Begin playing the best online slots with both bonus and real money.

LICENSING

Player safety is a key priority across the entire industry. The first thing you should look for when choosing a slot site to play at is whether or not it has a licence from the United Kingdom Gambling Commission (UKGC). You can easily discover whether a slot site is licensed by the UKGC or not by scrolling down to the bottom of the homepage. In the text at the bottom, a licensed casino will always indicate whether they are UKGC licensed or not.

All gambling operators serving customers in the UK must be licensed by the UKGC by law. At SlotsHawk we only list licensed slot sites. The UKGC licence is one of the hardest in the world to get. Any site applying for one must adhere to thorough background checks including audits, analysis and sustainability checks. The process is a long run and it can cost operators thousands of pounds, but it just goes to show that the sites which go through and complete this process to the UK government’s satisfaction can be trusted.

CUSTOMER SERVICE

You can quickly tell how well a company treats its customers based on the quality of their customer service. If a company (or in this case a slot site) is able to deal with a customer’s complaint in a pleasant and timely way, then the more pleasant and content the customers will tend to be in return. Nothing chases a customer away quite like a rude or unhelpful customer service team. When picking a slot site to play at, our reviewers have the following expectations:

• A live chat option which is ideally available 24/7.
• A native English speaker or staff member who speaks fluent English.
• Helpful and timely response.
• Not in a rush to help you.
• Can you reach them on a UK phone number?
• Is an email address available?

These expectations are always under consideration when the SlotsHawk team reviews slot sites. An excellent customer service is imperative for any slot site to receive a high mark from SlotsHawk.

CHOOSING THE BEST ONLINE SLOTS TO PLAY

There is plenty to consider when choosing which online slots you should play and for new players, it can be quite overwhelming due to the huge amount of choice out there.

One easy way to pick is simply to look at the slots which are trending. On most slot sites, there will be a bar which says something akin to trending games or hottest games. These are usually the most popular games the slot site offers and it’s not necessarily a bad option to look through these games and pick the most appealing one.

Another option is to ask for recommendations, but this only works if you have some friends who also like to play online slots. Alternatively, the experts here at SlotsHawk are always available to offer you a helping hand if and when you need one. The team here have spent countless hours in front of our screens playing all types of slots – we know our stuff and aim to ensure that you do too!

TRENDING SLOTS

As we have already mentioned, most online slot sites will have a trending slots category which showcases several or so of the hottest slots of the moment. These slots are ideal if you just want to test out a few games to see what you may or may not like. The majority of trending slots have already been reviewed by us as these tend to be the most-played slots.

The majority of these slots are usually good to play, but they are never usually the best ones, especially when you consider the amount of new slots released on a daily basis. When picking a slot to play you will want to look at a few factors which include; RTP, themes, payouts, volatility, jackpots and game mechanics and bonus rounds. Let’s take a closer look:

RTP (RETURN TO PLAYER)

This is something to note down when you are contemplating which slot game to play. RTP stands for return to player and is the theoretical amount that will be paid back to players over a period of time. For example, a slot with an RTP of 96% will pay back £96 for every £100 put into it. Of course, payments will vary when you factor in the luck aspect of a slot. Some will generate large payouts, some smaller and others will result in losses. Most players tend to lookout for slots with at least 96% RTP, whilst those slots which have an RTP of 97% or above are considered as high RTP slots. However, all slots are games of chance, so that doesn’t mean that slots with a lower RTP cannot pay out well.

THEMES

What kind of mise-en-scene most appeals to you? Do you like the Wild West with cowboys and Indians? Do you prefer something a little more futuristic, more akin to outer-space? The slots world is your oyster when it comes to the themes you can choose from. A slots aesthetic should factor into your choice when choosing one to play. What appeals to the eyes also appeals to the brain, after all.

How to choose a slot based on its theme is entirely your choice, we cannot really advise you on what you like after all. However, one of the most popular slot themes of the past couple of years has been fishing with the likes of Big Bass Bonanza and Fishin’ Frenzy hugely popular.

PAYOUTS

Every online slot is built with various ways in which they can make payouts. Pretty much every slot will have multipliers which look to pay out a percentage of your bet. The majority of slots will pay out the most when you enter the bonus game, but this can vary depending on what game you’re playing. Another component all slots have in common is that they all have a fixed maximum payout amount. Again, this varies from game to game, but the best paying slots can offer maximum payouts of up to 300,000x your initial wager and include slots like Tombstone RIP, Mayan Wild Mystery and Dead or Alive 2.

VOLATILITY (VARIANCE)

Volatility or variance as it is sometimes known is another important factor to consider. Do you like the idea of a slot which pays out frequently but in rather low amounts? If so, you should consider playing low volatility slots such as Bloodhunters, 10 Swords or Bloodsuckers. Or is your preference perhaps the opposite? Infrequent but large payouts? If so, think about playing slots with high volatility such as Land of the Free, DJ Fox and Pink Elephants 2. There are also some games which allow you to pick your own volatility level. All Wazdan slots will give you the chance to choose which volatility you would like to play with.

SLOT SITES GUIDES AND TIPS

Take advantage of plenty of years of our experience and learn about the various issues which may affect you when it comes to playing at UK slot sites. You will also find useful how-to guides as well as pages explaining exactly how we rate and review slot sites.

PAYMENT METHODS FOR ONLINE SLOTS

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, Boku 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.

GAMBLE AND PLAY RESPONSIBLY

Whichever slot site you choose to play at and whichever online slots you choose to play, it is of uttermost importance that you understand your limits. This means not spending any more than you can afford to lose. Whilst the majority of gamblers play slots because of the fun they offer, it is important to remember that over a set amount of time, slots are designed for you to lose money to the casino due to the RTP which always gives an edge to the house.

In credit to gambling operators, they always remind their players to be as safe as possible when gambling. You may be aware of Safer Gambling Week which is a yearly event which the majority of UK gambling operators take part in in order to publicise to gamblers a range of safety tips, strategies and warning signs which players should be aware of.

Safety Tips:

• Gamble only with what you can afford and never take money away from that which is set aside for bills etc.
• Set your limits and stick to them. Whether they are daily, weekly or monthly limits, never go over your limits if you do lose.
• If you notice that gambling is beginning to impact your life outside of gambling, then stop. Gambling should never get in the way of spending time with family or friends. Nor should you prioritise gambling over other pastimes such as sports, hobbies or social activities.
• If you need to stop yourself from gambling, then you can use GAMSTOP which will ban you from playing at all UKGC licensed gambling operators for a period of your choosing.

There are a number of ways you can assess yourself to understand whether you have become addicted to gambling or not:

• Spending money you cannot afford on gambling.
• You are finding it difficult to cease gambling.
• You are spending more time gambling then you would ideally want to.
• You think and talk about gambling during non gambling hours.
• You hide your gambling habits from others.
• You lie about your gambling habits.
• You lose interest in other activities and hobbies.
• You gamble your money until you have none left.
• You sell your goods and steal money to fund your gambling.
• You neglect other important responsibilities such as family, work and household priorities.
• You gamble more when you lose to get back to break even.
• Your gambling habits make you feel depressed, guilty or anxious.

There are also plenty of organisations and charities which can help you and offer you support if you do need treatment for gambling:

• Gamblock – This will block all gambling sites.
• AddictionHelper – Leading UK treatment centre for addictions.
• GamCare – Free support for anything to do with gambling addictions.

Lastly if your gambling has gotten out of control, then you should self exclude immediately and seek help. All UK licensed slot sites have a tool which you can use to exclude yourself immediately from playing at their sites.
