Written by Jean Prince

This guide will help you in your quest to find the best slot sites. Our team at SlotsHawk will give you their expert opinion on which sites they prefer and why. Find our selection of sites below, or scroll down for a full rundown on the top UK slot sites.

BEST UK SLOT SITES

After researching online casinos where you can play slots, we believe that the following are the 15 best slot sites that you can access from the UK. The sites have been selected by our team of industry experts here at SlotsHawk and vetted by our editor in chief Jean Prince. Jean has been reviewing and analysing casino and slot games for over 10 years, and he has put his stamp of approval on the sites.

The sites are ranked highly because they have several qualitative characteristics in common. For starters, they are all licensed by the UK Gambling Commission. Secondly, these sites specialise in online slots.

When it comes to payment methods, they have many different deposit and withdrawal options, including PayPal. The casinos also have a customer support team that is available 24/7. Finally, all players receive a welcome bonus when they sign up.

Visit the individual slots site review pages for a full review and to see what players and the SlotsHawk’s experts have to say.

1. ZETBET

Zetbet is a relatively new online casino on the market. Regardless of its age, we feel that it is one of the top slot sites in the UK due to its excellent casino games library and choice of slots.

With a collection of over 2,000 online slots from more than 120 game providers, you will be hard pressed to find a better slots catalogue. You will find everything from classic 3-reel slots to the newest video slots as well as some of the most popular Megaways slots.

Standout features:

• Over 2,000 slots from more than 120 game providers
• Slots updated weekly
• Online slots tournaments

What to consider: The welcome bonus comes with 35x wagering requirements. PlayOJO and Virgin Games have bonuses with zero wagering requirements which are much easier to clear.

Who is it good for? Zetbet is a great all round choice for all types of players. Thanks to one of the largest slots libraries in the industry, you will never run out of gaming options.

Our Verdict: Large collection of slots from a trusted brand, our opinion is that Zetbet is one of the top operators in the UK market.

2. PLAYOJO

PlayOJO is a firm favourite with many UK players. They made a name for themselves with their television commercials, but that is not why they are ranked so highly. PlayOJO gets high ratings thanks to their games library of 4,000 slots and their welcome bonus of 50 free spins. You can take advantage of the free spins against a deposit of £10, and any winnings from these have no wagering requirements!

In addition, PlayOJO offers some cool features that you will not find at your usual slot site, such as their Hot/Cold filter which allows you to filter out which slots that are currently paying out the most as well as the coldest ones which have not been paying out much lately. They also organise daily slot tournaments that you can participate in, sometimes for free.

Standout features:

• Massive slots library of 4,000 games
• Fun loyalty scheme with kickers
• No wagering requirements on any bonuses

What to consider: The two largest jackpots WowPot Jackpot and Mega Moolah are not available. Also, the deposit free spins can only be used on the slot game Book of Dead.

Who is it good for? PlayOJO is great for both new and experienced players alike thanks to their massive slots library and wager-free bonuses. Fans of the Dream Drop Jackpot take note, you can play all the slots in the series here. If you play regularly, we recommend taking part in the OJO levels rewards programme where you can win cash prizes, free spins and spins on the OJO wheel.

Our Verdict: Fair and fun casino with a fantastic collection of online slots. We fully support PlayOJO’s commitment to never having wagering requirements on any bonuses, something we hope more sites will follow in the future.

3. WINOMANIA

A lesser known casino which utilises live casino and slots on one platform, Winomania gives players the opportunity to play over 400 slots from well-known providers including NetEnt, NoLimit City and Red Tiger Gaming. Their selection of high volatility slots is particularly good including favourites like Big Bass Bonanza and Gates of Olympus.

Standout features:

• Excellent selection of high volatility slots
• Welcome package of £100 plus 100 free spins
• VIP club for loyal players

What to consider: The welcome bonus comes with 40x wagering requirements, which will be very hard to clear unless you play frequently.

Who is it good for? Winomania is best suited for players who play frequently. They offer bigger bonuses and rewards in comparison to other slot sites, but due to the high wagering requirements you need to play a lot to take full advantage of them. The VIP programme has some nice rewards, but they have to be earned by playing lots of games.

Our Verdict: A popular site with plenty of online slots to choose from. If you play enough, you can get some sizeable bonuses.

4. SKOL CASINO

Skol Casino is a slots powerhouse operated by White Hat Gaming. Since 2021, they have quickly built up a large selection with over 2,000 slots from more than 100 different game providers. Among those games you can find UK favourites such as Rainbow Riches, Fluffy Favourites and plenty of slots in the Big Bass series. In addition, the slots at Skol Casino have fantastic RTP rates across the board, all the way up to 99%.

“Skol Casino is my go-to choice because I can play all my favourite games here with the best RTP rates on the market”

– Stephen Cummings, Slots Analyst

Standout features:

• Over 2,000 slots from more than 100 game providers
• Slots with the highest RTP rates
• Five welcome bonuses

What to consider: 35x wagering requirements on all bonuses. This is around the industry average, but you still need to play plenty to clear through them.

Who is it good for? Skol Casino is superb for players who want to play slots with high RTP rates. Here you can find Book of 99, Monopoly Big Event and Mega Joker, all of which have a return-to-player percentage of 99%. They also have one of the best game selections alongside PlayOJO and Casumo, so you always have plenty of slots to choose from.

Our Verdict: Skol Casino is one of our favourite brands here at SlotsHawk. They promise a large number of slots with great RTP and generous welcome bonuses.

5. MRQ CASINO

With online slots in many different categories, MrQ Casino is an excellent site that ticks all the boxes. The majority of the slot games are video slots, but you can also play classic slots, jackpots, Megaways and Slingo. The slots come from well-known providers like Hacksaw Gaming, NoLimit City and NetEnt.

MrQ’s category of Slingo slots is worth checking out as they have 38 different ones to choose from. Only Slingo Casino has more. They also have many of the best RTP slots including 1429 Uncharted Seas and Blood Suckers with payouts of between 98-98.60%.

Standout features:

• Over 900 slots from top providers
• Wide range of Slingo games
• 75 no-wager free spins on the Big Bass Splash slot

What to consider: You must deposit and spend at least £20 in order to receive the no-wager spins on Big Bass Splash.

Who is it good for? MrQ Casino is best suited for sporadic players who are looking for online slots from well-known slot providers as over 20 of the most reputable names in the industry are featured here. Due to the absence of a loyalty system, frequent players want to choose another site like Casumo or PlayOJO.

Our Verdict: In our opinion, MrQ is one of the most underrated online slot sites in the United Kingdom. On top of an extensive slots library, their bonuses have no wagering requirements, which makes us believe they truly care about their players.

6. PLAYZEE

Playzee has a great game selection offering over 1,000 slots in different categories such as Megaways, standard video slots and their own branded “Zee games”. Their selection of progressive jackpots stands out with over 80 to choose from, including the two with the largest prize pools, Mega Moolah and WowPot Jackpot from Games Global.

“When I play I usually bet big or go for the large jackpots, and at Playzee I can do both.”

– Jean Prince, Editor in Chief

Standout features:

• The first deposit bonus of £300 is one of the biggest in the UK
• Fast withdrawals (usually processed within a few hours)
• Great selection of progressive jackpots

What to consider: While Playzee offers among the largest bonuses in the UK, you need to wager the bonus funds 35 times.

Who is it good for? Most players will find something to play at Playzee due to their game variety, but high rollers will thrive here because of the size of the bonuses and jackpots. Remember to check out their loyalty scheme where you can get reload bonuses of up to £500.

Our Verdict: Massive jackpots, big bonuses, and a large selection of games, Playzee is the number one site for high limit slot players.

7. SPINYOO

Boasting an extensive library of more than 1,000 slots from the top providers, even the most discerning players have something to play at SpinYoo. Their selection of slots from Red Tiger Gaming is outstanding with almost 200 to choose from.

If you are new to the site, you can try your luck with 100 free spins on five of the most popular slots of all time – Starburst, Book of Dead, Fire Joker, Gonzo’s Quest and Big Bass Bonanza. To get the free spins, you need to make a deposit of at least £20.

Standout features:

• Free spins on five different slot games
• Over 1,000 slots from well-known providers
• Huge variety of Red Tiger Gaming slots

What to consider: You will receive your free spins in bulks of 20 on the slots mentioned above. Each bulk of free spins has a £50 win cap, which is a bit of a letdown.

Who is it good for? SpinYoo is great for players who like free spins as the welcome bonus gives you 100 of those, and you can use them on multiple games too. If you have a weak spot for slots from Red Tiger Gaming you will also enjoy your time here as you can play almost all of them.

Our Verdict: Catering specifically to UK gamblers, SpinYoo is a sophisticated online casino with lots of great slots. We are big fans of their free spins bonus that allows you to test five of the best UK slots.

8. PUB CASINO

Our favourite new online slots website with over 1,000 titles from providers like Pragmatic Play, Relax Gaming and Microgaming. This selection includes everything from Slingo to jackpots to Megaways.

At Pub Casino, you can always find something new to play as they update their game library every week. Some of the best new slots currently on the site include Napoleon 2 Fat Stacks, Gates of Olympus 1000 and Bonanza Falls.

Standout features:

• 1,000 + slots
• New slots every week
• £100 first deposit bonus

What to consider: No slots from Push Gaming. Also, the 40x wagering requirements on the bonuses make them hard to clear.

Who is it good for? Featuring slots from most of the major providers, almost every player will find something to play here.

Our Verdict: Launched in 2023, Pub Casino is a great new addition to the UK market offering a large number of online slots. We like that they make sure to add new slots regularly.

9. ALL BRITISH CASINO

Just as the name suggests, All British Casino is a site built specifically for the UK market. Owned and operated by L&L Europe, you can play over 1,100 slots here from A-tier software providers like Relax Gaming, Pragmatic Play and Play’n GO.

We recommend checking out their own separate game category “British Favs” where you can find some of the slots that are currently the most popular with British players. In addition, All British Casino has a few branded games that you cannot find anywhere else like All British Dark Wolf and Slingo All British.

Standout features:

• Built exclusively for UK players
• British branded slots
• 10% cashback with no wagering requirements

What to consider: All British Casino only have slots from about 20 software providers. While games from most of the major providers are available, you will not find slots from smaller niched ones like Peter and Sons and Playbro.

Who is it good for? All British Casino is great for players who want to play the most popular slots on a reputable local UK site as almost all major slot providers are featured here.

Our Verdict: An established British brand with a rock solid library of online slots. The cashback adds great value for loyal players, especially in combination with the weekday promos.

10. HYPER CASINO

Promoting themselves as hyper, not just in name, but in everything they do, Hyper Casino has built everything on the site to reflect this statement. The sign-up process is fast, the website interface is clean, and the games load quickly. In addition, all withdrawals are processed within one working day.

In terms of gaming options, you can find just over 1,000 slots, mainly from providers like NetEnt, Relax Gaming and IGT. The latter have produced the iconic Cleopatra slots, so you can play those here.

Standout features:

• 1,000 slots
• Lightning fast registration process
• All withdrawals are processed within one working day

What to consider: Since Hyper Casino also is owned by L&L Europe, you will find pretty much the same slots here as at All British Casino. The two sites are different in other aspects. While All British have better bonuses, Hyper focuses more on speed and simplicity.

Who is it good for? Hyper Casino is ideal for players who just want to have a quick and casual gambling session. While the slot selection may be better at other sites, the average player still has enough to choose from.

Our Verdict: Straightforward registration process, decent selection of slots and among the fastest withdrawal times. At Hyper Casino you can deposit, play and withdraw quickly without unnecessary fuss. We like their new and updated space themed website.

11. LUCKSTER

Our favourite slot site powered by Aspire Global. Launched in 2022, Luckster went online on the UK market with over 1,000 quality slots. Most of the slots are provided by NetEnt, Microgaming and Play’n GO. We have to give an extra thumbs up for the selection of Blueprint slots as there are over 100 to choose from, including all games in the Eye of Horus and Fishin’ Frenzy series.

Apart from online slots, you can also find other casino games like roulette, blackjack and a live casino from Evolution Gaming.

Standout features:

• Over 1,000 slots from more than 50 providers
• Up to £200 welcome bonus plus free spins
• Original website theme

What to consider: Lacking some of the jackpot slots with the biggest prize pools like the WowPot Jackpot and Mega Fortune. If you want to play those, consider a site like Casumo, Playzee or Pub Casino instead.

Who is it good for? If you like other sites on the Aspire Global platform like PlayFrank, Atlantic Spins and Spin Rio, you will love Luckster as they offer a very similar selection of slots. However, since Luckster is newer, the site naturally offers a slightly better gaming experience.

Our Verdict: Specialising in online slots and with a respectable sign-up bonus, Luckster is an Irish themed online casino which offers a great gaming experience.

12. VIRGIN GAMES

Virgin Games is one of the most established slots sites on this list. They have been online since 2004, and offer their players just over 900 slot games. The games are developed by some of the best software developers on the market such as NetEnt, IGT and Yggdrasil Gaming. They are also one of the few sites where you can play Double Bubble.

“I always preferred Virgin Games. I feel safe when playing here and I really enjoy the free games.”

– Yvonne Greenwood, Content Writer

Standout features:

• Daily free slots with real money prizes
• Trusted brand with almost 20 years of experience
• Have all Double Bubble slots

What to consider: The welcome deposit free spins on Double Bubble are only valued at 1p each, which makes it one of the smallest slots bonuses around.

Who is it good for? If security and stability are your priorities, Virgin Games is a good choice. There is a reason why they have been around for almost two decades. If you have made at least one lifetime deposit of £10 or more, we recommend taking part in their daily free games as you can win up to £750 or 50 free spins risk-free.

Our Verdict: While Virgin may be known for their Trans-Atlantic flights by some, they also have a strong reputation in the online gambling industry. We regard them as one of the most trusted UK slot sites. Plus points for hosting bingo and poker.

13. BETFRED

Speaking about safety, security and stability, one of the few sites that can beat Virgin Games’ legacy is BetFred. Founded in 1967, and with an online presence since 2004, BetFred is one of the most well-known UK gambling brands.

Originally a bookmaker, BetFred now also offers online slots. You can choose from a selection of over 600 slot machines from top-tier providers like Microgaming, NetEnt and Scientific Games. If you like jackpot games, you will be happy with BetFred as they stock slots from the popular Age of the Gods series by Playtech.

Standout features:

• Great selection of Playtech slots
• One of the most trusted brands in the UK
• £5 minimum deposit

What to consider: The total number of slot games is on the lower side compared to some other fully slots dedicated sites.

Who is it good for? If you enjoy both slots and betting, BetFred is your ideal site. It is also a good option for players on a small budget as it is possible to make deposits from £5, compared to other sites who usually require you to deposit at least £10 or £20.

Our Verdict: Due to their extensive history, it is hard to find a more reliable site than BetFred. You can feel 100% safe and secure when playing here.

14. RAINBOW RICHES CASINO

Rainbow Riches Casino is a unique website built for Rainbow Riches slots. In addition to these, you can play a variety of video slots, classic slots and Slingo slots. In total, you can play a little over 600 slots here. You can play these in your browser or via their app.

Standout features:

• All Rainbow Riches slots are available
• Daily free games
• Wager-free bonuses

What to consider: The selection of slots outside of Rainbow Riches leaves a little to ask for.

Who is it good for? If your main choice of game is slots in the Rainbow Riches series, you will feel like home here as you can play all of them. There are also some nice wager-free bonuses to take advantage of as well as daily free games.

Our Verdict: The perfect place to play Rainbow Riches slots.

15. BALLY CASINO

Launched late in 2023, Bally Casino is the newest site from Bally’s Corporation owned Gamesys. Here you can play a variation of casino games as well as 450 slots. There are other slot sites with a greater number of games, but Bally stands out thanks to the quality of the games they do have since all of them come from reputable software providers like NetEnt, Pragmatic Play and Push Gaming.

You also have the option to play some Gamesys exclusive titles such as Double Bubble and Secrets of the Phoenix. Right now, Bally Casino is the only site where you can get free spins on Secrets of the Phoenix Megaways.

Standout features:

• New site from a trusted company
• Daily free games
• Free spins with no wagering requirements

What to consider: Relatively low number of slots compared to other sites. You will not be able to play many slots outside of the main game developers. We expect Bally to add more slots in 2024 as they establish themselves in the UK.

Who is it good for? Bally is good for players who want to play slots from reputable providers on a site operated by a trusted company. Also, the free games give you a chance to win both free spins and cash that you can spend on slots.

Our Verdict: As the latest addition in the Gamesys portfolio of sites, you know exactly what you get at Bally Casino. Pretty similar slots selection to Virgin Games and Rainbow Riches Casino, but with wager-free spins on another game.

BEST 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.

Four high quality slot sites are Casumo casino, PlayOJO, Winomania and Skol Casino.

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:

1. PlayOJO Casino
2. Skol Casino
3. 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:

1. Skol Casino
2. All British Casino
3. 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:

1. All British Casino
2. Playzee
3. 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:

1. Mr Rex Casino
2. Casiplay
3. 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 2024. For more info, see our guide to UK slots apps.

BEST NO WAGERING SLOT SITES

The best no wagering slot sites are:

1. Betfred Casino
2. MrQ Casino
3. 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:

1. Slingo Casino
2. Playzee
3. 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.

• Specialist sign up bonuses for slots players – These online slots sites attract UK slots players by offering them bonus spins when signing up. These free spins can be used to try out slots casinos and can help to increase your bank roll. There are some sites which will give free slots spins with no wagering requirements too. Slot sites can be more appealing than established casino brands by giving better sign up bonuses for slots gamblers.
• Latest slots – From the best slots developers to the newest ones, they will often partner up with operators which specialise in online slot games. Why? Because they are more likely to attract casino players and the developers make money when their games are played. For more information, you can check out our list of the top online slots further down this guide. Other than that, online slot sites will also stock the top jackpot slots as well as numerous quality high volatility games and Megaways slot machines.
• Payment methods – In comparison with three years ago, there is now a wide range of different online payment methods which can be used for topping up casino accounts. Along with the usual methods such as debit cards, most online slot sites now accept payments via eWallets such as PayPal and payments via mobile including Apple Pay.
• Trustworthy – All of the slot websites on this page are regulated and licensed by the UK Gambling Commission. This means they are proven to be safe with top of the range security in order to protect players accounts.
• Technological advancements – Slot sites are built with the latest technology which is why the best ones are fully compatible with mobile devices. The fact that they are built with the newest technology, means that they are ultra-fast and easy to use. The ease of layout ensures that playing casino games has never been more fun.

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 2024 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.

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.
