Detailed Look into the Top 10 Slot Sites in the UK

Here we deep dive into our top 10 slot sites for UK players. Our expert team evaluate sites against a list of criteria and points out the pros and cons to give you comprehensive and unbiased reviews.

We look for an operating UK license, a good range of slot games from reputable providers, casino bonuses and promotions, popular payment methods, quick withdrawals and a suitable mobile offering amongst other factors.

1. Best UK Slot Site 2024: Duelz Casinoduelz-casino

Top Reasons to Play at Duelz Casino 

  • 1,000+ slots
  • 6 minute average cashouts (with no fees)
  • 10% cashback every Friday
  • Duelz Prizes – take on other players
  • Nearly £10,000 of tournament cash prizes weekly
  • New slots added instantly

Positives: With over 1,000 slot games from the best providers, Duelz Casino is known for being the instant cashout slot site. Taking an average of 6 minutes, all withdrawals are free too. The welcome offer is generous (100% bonus up to £100 plus 100 free spins), and the way they treat their existing customers is top-notch. With 10% cashback weekly, you can take on other Duelz players to win cash prizes and bonuses. There are also free slot tournaments every 15 minutes with nearly £10,000 worth of cash prizes up for grabs every week.

Negatives: With no dedicated iOS or Android mobile apps, Duelz is missing a few top providers including Hacksaw Gaming, Blueprint Gaming, Thunderkick and Playtech.

Our Verdict: Duelz Casino is a reputable UK site with the best online slots available. With a good matched bonus and free spins available on your first deposit, they focus on free slot tournaments, weekly cashback and Duelz Prizes where you take on other players for prizes. It’s a unique casino that has everything a new and existing player could need from numerous payment options to super fast withdrawals.

2. Most Online Slots: Mr Vegas

mr-vegas-casino

Top Reasons to Play at Mr Vegas Casino

  • 4,000+ slots including 160+ providers
  • Lots of Megaways + jackpot slots
  • 12 to 24 hour cashouts
  • PayPal-friendly casino
  • Search by slots provider
  • Part of reputable Videoslots Casino

Positives: Without question, Mr Vegas Casino offers you the largest selection of online slot games. Over 4,000 slot titles are available which includes a huge range of Megaways and progressive jackpot games. Part of Videoslots Casino, you have all the most popular payment methods including PayPal. With 24 hour cashouts that are free of any fees, new players are welcomed with a huge 100% bonus up to £400 plus 150 Starburst spins.

Negatives: Mr Vegas only offers their customers 1 free withdrawal per day (extras ones are subject to a £2.50 fee). They don’t have Apple Pay or Google Pay and you cannot see the progressive amounts on the site menus for their jackpot slots.

Our Verdict: With the biggest slots portfolio anywhere online, Videoslots is a must if you’re a slots player (well, you should be being on Online-Slot.co.uk). Offering all the popular payment methods, their customer support is top-notch and their welcome bonus is very generous indeed.

3. Highest Payouts: MrQ

mrq-casino

Top Reasons to Play at MrQ Casino 

  • 1,000+ slots
  • Highest RTP rates available on all slots
  • Slick website design/easy-to-use
  • No wagering requirements on any promotions
  • iOS + Android mobile apps
  • Instant payout casino + PayPal/Pay by Mobile

Positives: The reputable MrQ Casino is without doubt the highest payout slot site. With over 1,000 online slots, they offer you the highest RTP rate on all their games. For their welcome offer and existing customer promotions, they also offer no wagering requirements. That’s not all. They have lots of payment methods, instant cashouts and both iOS and Android mobile apps. MrQ refers to themselves as “all fun and no faff”. We certainly agree with this statement.

Negatives: With many of the best slot sites offering a larger slots portfolio, they don’t have the best selection of jackpot slots compared to others. A minor gripe but there are no slots from Yggdrasil Gaming and Playtech.

Our Verdict: MrQ has a very easy-to-use website and dedicated mobile apps. With a decent selection of slot games, their standout feature is that all slots offer the highest RTP rate available. Mobile players can use also the Pay by Mobile method which is handy. Lastly, there are lots of rewards for existing customers with, you guessed it, no wagering requirements.

4. Best Mobile Product: Casumo

casumo-casino

Top Reasons to Play at Casumo Casino 

  • 2,100+ slots
  • Superb iOS and Android mobile apps
  • Instant cashouts including PayPal + Apple Pay
  • Trusted UK site – formed in 2012
  • Casumo Reel Races (slot tournaments)
  • Wide selection of jackpot slots available

Positives: The formidable Casumo Casino has been around since 2012 and for good reason. With more than 2,100 online slots to play, customers can enjoy a slick website and/or dedicated iOS and Android mobile apps. There are lots of popular payment methods, instant withdrawals and no fees. Reel Races offer daily slot tournaments and there are lots of promotions/offers. You can also benefit from 140+ progressive jackpot slots offering and a 100% bonus up to £100 plus 20 bonus spins when you make your first deposit.

Negatives: Casumo could do with a few more payment methods and more filtering options in their ‘Games’ section. They also removed their no deposit bonus recently. We are nit-picking really because we have to.

Our Verdict: Casumo is a solid option if you like playing at mobile slot sites. Their mobile apps are great with the selection of slots also impressive. Trustworthy and reputable, you have games from the top providers including an impeccable jackpot slots list. Finally, you have regular slot tournaments with decent prize pools (£2,000+).

5. Top Bonus: Playzee

playzee-casino

Top Reasons to Play at Playzee Casino 

  • 3,700+ slots
  • Zee Daily Offers
  • 2 to 24 hour cashouts (PayPal within minutes)
  • Trusted UK site – formed in 2012
  • ZeeClub loyalty programme
  • Wide selection of jackpot slots available

Positives: Since forming in 2018, Playzee Casino has become a UK-focused choice to play your favourite slot game. With more than 3,700 online slots at your disposal, you have games from the best providers. Offering lots of payment methods with 2-24 hour cashouts, existing customers can benefit from Zee Daily Offers as well as a loyalty programme. However, Playzee has the top slot site bonus with a 100% welcome bonus up to £300, 150 Starburst Zee Spins as well as 500 Zee Points.

Negatives: Highly rated by our team, Playzee has no Playtech or Yggdrasil Gaming slots. In terms of the welcome bonus, it comes with 35 x deposit plus bonus wagering requirements which is a little high. The Daily Zee Spins have a £50 win cap.

Our Verdict: Playzee is one of our top rate slot sites and for good reason. With a great selection of online slots, they have all the payment methods in place including lightning-fast withdrawals. Offering a huge welcome offer and lots of promotions/offers for existing players, they display all RTP rates for their slots in the ‘RTP’ link at the bottom of the site.

6. Best No Wagering Slot Site: PlayOJO

playojo-casino

Top Reasons to Play at PlayOJO Casino 

  • 3,000+ slots
  • No wagering casino
  • iOS + Android mobile apps
  • Exclusive welcome offer for Online-Slot.co.uk readers
  • OJOplus – free cash every time you play
  • Quick cashouts including weekends

Positives: Formed in 2017, PlayOJO Casino is one of the best sites with no wagering offers. Dubbed the ‘fair casino’, and with plenty of industry awards to their name, there is money back on every spin, wins from bonuses are paid in cash and there no wagering requirements, ever. Add 3,000+ online slots, dedicated mobile apps and fast cashouts with no fees, you are also welcomed with an exclusive 80 free spins on your first deposit.

Negatives: PlayOJO doesn’t have as many payment methods as other slots sites. They have 6 at present (including PayPal and Apple Pay) but could offer some more if we’re being picky.

Our Verdict: PlayOJO Casino is a trusted site that features heavily on adverts across UK television. Offering a superb slots portfolio, the fair casino doesn’t have wagering requirements ever and offers you money back on each spin. All bonuses are in cash too. Withdrawals are simple and quick and you can play with iOS and Android mobile apps.

7. Best Slot Site with a No Deposit Offer: PokerStars

pokerstars-casino

Top Reasons to Play at PokerStars Casino 

  • 2,500+ slots
  • Lots of payment methods including Apple Pay, PayPal + Google Pay
  • Dedicated Mobile Apps (iOS + Android)
  • Exclusive no deposit free spins + 100% bonus up to £200
  • Plenty of exclusive slots (mainly from Pragmatic Play)
  • E-wallet cashouts within 1 hour

Positives: With more than 2,500 online slots including lots of exclusive games, PokerStars Casino really takes care of their customers with lots of promotions/offers. Offering a wide range of payment methods and 1 hour e-wallet withdrawals, you can also play on iOS and Android mobile apps. They are the top no deposit slot site as Online-Slot.co.uk readers are treated to an exclusive 100 no deposit free spins plus a 100% bonus up to £200.

Negatives: Despite having an exclusive offer, the 100% welcome bonus up to £200 is only valid when using your debit card. Other payment methods are not included (i.e. PayPal). They also don’t have a full allocation of Novomatic slots if we’re being over-critical.

Our Verdict: Apart from PokerStars Casino offering superb no deposit free spins offer and generous welcome bonus, they boast a great selection of slots including plenty of exclusively-produced games. Available via your browser and mobile apps, you can deposit using a large array of payment methods including Apple Pay and Google Pay (great for mobile players). They also take care of existing customers with a steady stream of promotions and rewards.

8. Fastest Cashouts: Regal Wins

regal-wins

Top Reasons to Play at Regal Wins Casino 

  • 800+ slots
  • Instant withdrawals with no fees
  • Loyalty Program
  • Free UK phone support
  • PayPal and Apple Pay are available
  • New slots are added regularly

Positives: The standout positive is the payout speed. Many casinos are quick nowadays, but Regal Wins promises most withdrawals within 15 minutes. It’s actually instant for most methods but they can’t commit to saying that in case it’s not for whatever reason. This blows most competitors out of the water and is one of the reasons why players love Regal Wins. The welcome offer is great and so too is the loyalty program, which many casinos don’t offer.

Negatives: It would be nice to have seen a dedicated mobile app on iOS and Android, but the mobile browser does the job. If I were being picky, it would also be great to see more slots available. There’s plenty to choose from, but a little more variety wouldn’t hurt. In terms of customer support, it’s great that there is live chat, email and a UK telephone support number. However, with many competitors offering 24/7 live chat, it’s a shame this casino doesn’t.

How We Rate Slot Sites

Boasting 30+ years of combined industry experience, the team here at Online-Slot.co.uk lives and breathes online slots. Any slots sites we list here have gone through a rigorous process whereby we register, deposit and play the slots they offer. With so many important aspects to consider, below is a summary of our review criteria:

  • UKGC-Licensed: All slot sites here at Online-Slot.co.uk need a valid operating license from the UK Gambling Commission. This ensures that certain standards are upheld including suitability, identity and ownership, finances, integrity, competence and criminality.
  • Slot Game Offering: We look at the variety of online slots available including games from licensed and reputable slot providers such as NetEnt, Play ‘n GO and Microgaming. This includes a deep dive into progressive jackpot, classic, grid and Megaways slots as well as how quickly they add new releases and if they offer any exclusive titles.
  • Website Usability & Mobile Apps: We assess how easy a slot site’s website is to use including a simple registration process, filters, personalisation options and clear presentation of information. Then we delve into the mobile offering which includes dedicated iOS/Android apps and their game selection available.
  • Customer Offers & Loyalty Scheme: A welcome bonus is a must for new customers so we look at how fair the Terms & Conditions are (i.e. wagering requirements, cashout limits, expiry dates), what ongoing promotions and offers are available to regular customers and how they are rewarded for playing long term.
  • Banking & Payment Methods: A good range of payment options is vital at UK slot sites. We look at the ways customers can deposit and withdraw securely including if there are any fees or restrictions (i.e. for welcome bonuses). Importantly, we assess how quickly you can withdraw your winnings.
  • Customer Service: How a site treats its customers is crucial to their success. We evaluate how players can get in touch, the availability and responsiveness of the customer support team and what information is available on the website (i.e. FAQs/Help centre).
  • Overall Experience: Whilst an online slots site may tick many boxes, it’s important to assess the overall customer experience. This can include access to help and safer gambling tools, unique features (such as customisable lobbies) and how a site conducts itself (i.e. exclusive promotions, information transparency and customer focus).

Understanding the Slot Providers

how-we-rate-slot-sites-online-slots-slot-providers

Whilst not all slot machine websites have games from all the providers mentioned, a good mix of slot providers will give you a wide choice of online slots to play. Some of the best online slot sites do have most online slots and providers covered. Below is an overview of the top providers with their most popular games:

  • NetEnt: Founded in 1996, NetEnt slots are available at nearly all UK slot sites and for good reason. With over 250 slot games to choose from, they are responsible for launching the Avalanches feature (or cascades/tumbles), cinematic quality style graphics and superb jackpot titles.
  • Play ‘n GO: Formed in 1997, Play ‘n GO is a top provider with a new slot game released every week. A household name since the launch of Book of Dead, they have hundreds of slots covering many themes. With high-definition graphics, enticing bonus features and great gameplay, Play ‘n GO were the first to offer mobile slots.
  • Nolimit City: Since launching in 2014, Nolimit City is the slot provider that pushes boundaries and create superb slot games with controversial themes, unique mechanics and genre-defining bonus features. With a very loyal base of players, their slots are highly anticipated and different to anything you’ll find online.
  • Big Time Gaming: The award-winning Big Time Gaming is the creator of Megaways with Dragon Born released in 2016. Since Bonanza was unleashed, they’ve licensed their shape-shifting mechanic to other providers. They also offer you Megaclusters, Megapays and Megaquads mechanics for a unique slots experience.
  • Microgaming: Microgaming was the first slot provider back in 1994. With over 750 slot games, they are responsible for the world’s first branded game (Lara Croft: Tomb Raider) and the world’s biggest progressive jackpot network. Their jackpot slots are have paid out world-record numbers over the years. You’ll be hard pressed to find popular slot sites without Microgaming titles.
  • Pragmatic Play: Founded in 2015, Pragmatic Play offers hundred of slot games with superb gameplay, exciting bonus features and excellent design/animations. Mobile/tablet friendly, players can win jackpots and cash prizes when playing their slots. Their games are available at most slot websites with many welcome offers using their slots for free spins.
  • Playtech: Formed in 1999, Playtech has many great slots including many branded titles (The Walking Dead and Breaking Bad). With great jackpot games, their Age of the Gods series is iconic covering various Greek gods with amazing gameplay and 4 progressive jackpots.
  • Relax Gaming: Founded in 2018, Relax Gaming has become one of the top providers in little time. With amazing games like the Money Train series, they are known for the Dream Drop jackpot slots which has created 12 millionaires since it’s release in May 2022.
  • Push Gaming: Founded in 2010, Push Gaming are a mobile-first provider with a focus on quality. Their beautifully-designed games are unique, have innovative bonus features and big win potential in general. Push are responsible for some cult favourite slots too.

The Different Types of Slot Games

Additionally, we also look out for UK slot sites that offer:

  • New Slot Games: A clear indicator of a good slot site is how quickly new titles are added. New online slots are released almost daily with 100+ new titles available every single month. The better sites will add the new releases early on the launch date.
  • Exclusive Slots/Early Releases: The likes of LeoVegas, Party Casino, PokerStars Casino and Casumo frequently have slots not available anywhere else (for a limited period or exclusively).
  • Jackpot Slots: Important to many players, some progressive jackpot slots offer life-changing jackpots. We look for the likes of Mega Moolah, Mega Fortune and Hall of Gods which offer jackpots that can reach 7 or even 8 figures.
  • Megaways Slots: They’ve become very popular in recent years due to Bonanza being released in December 2016. Since then, Big Time Gaming has released many more Megaways slot games and has licensed Megaways to many other providers. As a result, there are 100s of Megaways games available.
  • Grid Slots: There’s been a recent emergence in grid slots which are games that use a Cluster Pays mechanic. Played normally on a square grid (from 3×3 to 9×9 typically), winning combinations are formed when clusters of symbols land adjacent to one another, in any position.
  • Classic Slots: Whilst there are new slot games almost daily, players love classic Las Vegas games and stick to the first slots they played. Players who have played at land-based casinos, pubs and even arcades are more likely to stick to what they know. For example, players will play at slot sites with Fluffy Favourites or Starburst.

The Most Popular Slot Themes

While there are many different types of slots, there are also many different themes to them that can be enjoyed at the best online slot sites. From Irish, Egyptian and Norse Mythology to Sweets, Animals and Gangster, there are plenty to choose from. The following is a list of the top 10 themes you can play at your chosen online slot sites. Feel free to click through to understand everything you need to know about that theme and the games available:

  1. Fishing slots
  2. Egyptian slots
  3. Norse Mythology slots
  4. Horror slots
  5. Asian slots
  6. Irish slots
  7. Animal slots
  8. Wild West slots
  9. Sweet slots
  10. Space slots

The Best Paying Slot Sites & RTP

how-we-rate-slot-sites-best-paying-rtp

Whilst all the best slot sites for payouts will offer you slot games, we look for ones that offer the highest payout rates. This means the best paying gambling sites in the UK basically. It could also mean the highest RTP rates.

Whilst a lot depends on the slot providers found at a particular slot site, having a range of online slots with an RTP of 97%+ is favourable. If you refer to the top RTP slots, the best slots for payouts include Relax Gaming’s Book of 99, Thunderkick’s 1429 Uncharted Seas and NetEnt’s Blood Suckers amongst others.

However, the other aspect is whether UK slot sites offer the highest payouts for their online slots. If you take MrQ Casino, they guarantee the top RTP rate for all their games. Most others mix and match between the highest and lowest payout rates. Our blog post looks at varying RTP rates at slot sites in greater detail.

Understanding the Website/Mobile Usability

how-we-rate-slot-sites-website-mobile-usability

A good user experience is a must these days and having a website that is easy to use is vital. Offering 1,000+ slot games is great but how easy can you find what you’re looking for? Online slots with a filtering system are preferred as it’s simple to find slots by a certain provider or by a theme for example.

We look for sites that are clearly laid out and have dedicated sections for various types of online slots. This can include Megaways, progressive jackpots and slot providers. A solid search function is key for us and can save you from scrolling aimlessly amongst thousands of options.

Then you have the small matter of mobile devices. According to Uswitch, it’s predicted that 95% of the UK population will be using a smartphone by 2025. Mobile usage has surpassed desktop (laptop or PC) so mobile usability for slot sites is a must. With more and more slot providers being ‘mobile-first’ (such as Push Gaming and 4ThePlayer), there has been a rise in mobile apps.

UK slot sites have developed iOS and Android apps to engage their customers further. Whilst they are not a must, playing online slots in your favourite casino’s app is a big pull for players. All the functionality of full-blown websites must be replicated on their mobile versions/apps in order to appeal to the players that use them.

Uncover Bonuses & Promotions

how-we-rate-slot-sites-rewards

Slots bonuses are, for many, the initial attraction when joining a top UK slots site. There are also promotions and offers, tournaments and loyalty schemes. With a focus on slot sites with a welcome bonus, below is what we look for from the very best sites:

  • 100% Wagering Requirement Contributions: Having slot games contribute fully (100%) to the wagering requirements is a must in our eyes. There are obviously some exceptions (like high RTP slots) but the majority should be valid. Luckily, nearly all slot sites allow 100% wagering from their slot games.
  • Free Spins: Many slot sites with a welcome bonus also offer free spins on slot games. This can also mean no deposit bonuses that include free spins or spins upon your first deposit. The most reputable slot sites will have offers on the most popular slots like Starburst and Book of Dead. Many sites also offer free spins on new slot games regularly.
  • No Deposit Bonuses: Offering a no deposit bonus allows users to sample a site without having to make a deposit. These come in the form of free spins which sometimes have no wagering requirements/restrictions. It’s not easy to find the best slot sites with no deposit needed as they’re rare nowadays. However, we list what’s currently available on our site.
  • Slot Tournaments: They have become a new feature/concept at the top UK slot sites recently. The likes of NetBet Casino and Unibet Casino offer tournaments on the best or new slot games. Importantly, they are a great way of earning rewards such as cash, bonuses or free spins whilst playing your favourite online slots.
  • Daily Bonuses: many of the best slot sites offer daily offers for their customers. These include reload bonuses and free spins on popular slot games.
  • Promotions/Offers for Existing Players: Whilst a great welcome offer is also appealing, the real fun begins once you’re through the door so to speak. The best slot sites will take care of their customers with various promotions, offers and rewards. This includes cash prize pools, free spins, cashback, deposit bonuses, birthday bonuses and the chance to win tickets to major sporting events or even holidays.

For more details, check out our dedicated page to the best slot bonuses where we dig much deeper into the subject matter.

Recognise Available Payment Methods & Cashout Times

how-we-rate-slot-sites-payment-methods-cashout-times

Playing slots is what you want to do but being able to deposit and withdraw is a crucial part in doing that. Whilst most slot sites will offer debit card deposits, having a range of payment methods is important to many.

Playing at UK slot sites that take PayPal is preferred by many players but casinos should also offer the following popular payment methods in general:

  • Debit Cards: available at all slot sites and valid for all welcome offers
  • PayPal: quick deposits and cashouts and a mark of trustworthiness
  • Neteller: popular e-wallet solution offering quick withdrawals
  • Skrill: another e-wallet favourite with fast cashouts
  • Apple Pay: growing in popularity and popular with iOS smartphone users
  • Trustly: like a debit card but instant deposits and free withdrawals

The best slots sites will also have newer payment methods like MuchBetter, Google Pay and Boku which are aimed at mobile slots players. You should also consider the minimum deposit amount with £10 as the average. However, Pay by Mobile casinos cap the deposit limit for options like Boku and Payforit at £30. Make sure deposits are free and have no charges.

Whilst it may be easy to deposit, a sign of a good slot site is how quickly they process withdrawal requests (i.e. slot sites with fast withdrawals). The best ones will process cashouts within a matter of hours or even minutes.

On average, expect e-wallet cashouts to hit your account within 24 hours. As for debit cards and bank transfers, between 1 and 3 days is the average. Below is a table summarising the most important payment method factors. It includes average deposit and cashout limits as well as withdrawal speeds and fees:

Method Min Deposit Cashout Time Min Cashout
debit-cards £10 1-3 Days £10
paypal £10 1-24 Hours £10
apple-pay £10 1-3 Days £10
skrill £10 1-24 Hours £10
neteller £10 1-24 Hours £10
muchbetter £10 1-24 Hours £10
paysafecard £10 NA NA
bank-transfer-general £20 2-5 Days £20
g-pay £10 1-3 Days £10
boku £10 NA NA
trustly £10 5-15 minutes £10

To find out which sites process withdrawals the quickest, check out our Fast Payout Casinos page. This includes those offer under 1 hour withdrawals.

Additionally, you need to consider fees for both depositing and withdrawing. On the whole, depositing is normally free. Some withdrawals can come with small fees, albeit small. The best slots sites will process your withdrawals quickly and for free. Make sure to read the fine print when requesting a cashout.

Slot sites that accept credit cards are not licensed in the UK. This is because the UKGC has prohibited depositing at online slot websites with credit cards, since April 2020. If you see credit cards on offer as a payment method, run.

Licensed by the UK Gambling Commission

how-we-rate-slot-sites-uk-gambling-commission

First and foremost, slot site operators in the UK need to be licensed and regulated by the Gambling Commission. Also known as the UKGC, they were set up under the Gambling Act 2005 to regulate commercial gambling in the UK. They ensure licensees follow the License Conditions and Codes of Practice. Their aims include:

  • Prevent gambling from being a source of crime or disorder
  • Ensure that gambling is fair and transparent
  • Protect children and vulnerable persons from harm or exploitation
  • Advice and guidance

To check if the site you’re playing at is licensed by the UKGC, check the UKGC’s public register. Here, you will find a public log of all license holders with an easy-to-use search function. Slot sites should display a British Gambling Commission-licensed status on their websites. It’s normally found in the footer sections.

If a slots site doesn’t follow its rules and regulations, the UKGC will safeguard players by taking action which can include fines and a license suspension.

Reassuringly, all online slot sites listed here are licensed by the Gambling Commission and have a fully operational trading license. We also look at the companies behind the sites to ensure your safety and protection. Whilst many new sites pop up all the time, we like to know where we play our favourite slot games and if it’s safe to do so.

Finally, slot sites not on Gamstop are not recommended. This means they are not licensed by the UK Gambling Commission so your funds may be at risk. There is nothing stopping these slot websites from keeping your money as they don’t have to adhere to the strict practices and guidelines put in place by the UKGC.

Casino Registration & Account Verification

Imagine liking the range of slot games and providers as well as the welcome bonus and you come across a complex and long-winded sign-up process. Being able to register easily at a slot site is a must. A simple registration process will get you playing your favourite online slots in a matter of minutes, or seconds in some cases.

With that in mind, it may appear that you might be playing at places with no verification. In fact, these slot casino sites add automatic verification to the registration process. Whilst it may seem that no ID documents are needed, the best sites verify your identity automatically in the background.

According to the UKGC, “all online gambling businesses must ask you to prove your age and identity before you gamble”.

If you provide accurate and correct information, the automatic verification will be successful and you can start playing right away. It’s important to state that you may be required to provide verification documents further down the line (i.e. when requesting a withdrawal). Anyway, here are 5 of the top automatic, or no, verification sites:

🥇 Duelz Casino Our top UK site
💎 LeoVegas Casino Most slot providers
🎁 Playzee Casino Top slots offer
🚨 Unibet Casino Most progressive jackpot slots
🎰 Party Casino Best site for exclusive games

Safer Gambling Tools are Important

how-we-rate-slot-sites-safer-gambling-tools

With all licensed slots sites in the UK committed to responsible gambling, there are various tools available to ensure you enjoy playing slots online safely, sensibly and responsibly. These include:

  • Access to Gambling Activity
  • Deposit Limits
  • Loss Limits
  • Wager Limits
  • Reality Checks
  • Login Blocks
  • Take a Break
  • Self-Exclusion

Certain operators allow you to block your ability to play a specific slot game or to deposit on certain days or at certain times. All trusted slots websites will have a dedicated Responsible Gambling/Gaming section which highlights the tools and measures they have in place.

At Online-Slot.co.uk, we have our own page for responsible gambling which highlights measures, common signs of problem gambling and where to get help.

Finding Help at Slot Sites

how-we-rate-slot-sites-customer-support

Being able to contact a slot site’s support team is an important factor sometimes overlooked. You may need to query a promotion or might need help withdrawing your winnings. Having a reliable customer service team in place is crucial to a casino’s reliability and success.

Whilst picking up the phone nowadays has by and large become redundant, there should be a number of ways you can get in touch if you have any questions, queries or issues. The best slot sites offer various ways you can get help including:

  • Live Chat: The quickest way normally to contact support
  • Telephone: A UK freephone number is ideal
  • Online Services: WhatsApp and Skype are popular methods of communicating these days
  • Email/Online Form: Having an email address is a must
  • Social Media: having active Facebook, Instagram + Twitter accounts helps
  • FAQs: An extensive help section on the website/app can help cover most queries
  • Callback: Some sites offer to call you back at a time convenient to you

Whilst most UK slot sites will offer most of their contact methods, the Live Chat function has become the most popular way of communicating with a support team. Everything is written down in black and white with some sites sending you a transcript of your interaction with them via email. This allows for your documentation to be documented if you wish. With Live Chat, you can send attachments (like copies of ID), send voice notes and even make calls.

Whilst having all these ways to interact with a slots casino’s support team is great, response times are equally if not more important. You don’t want to be waiting for hours to hear back regarding a small query. The best slot sites will be with you in a few minutes at most, even during peak hours.

The Difference Between Independent and White Label Slot Sites

With hundreds of slot sites available in the UK, you may choose between a standalone site or white label (also known as a skin). An independent slots casino is individual and operates fully independently. The likes of LeoVegas and Casumo are standalone sites. With a personal feel, they stand out from the crowd and can offer a unique service and proposition to their customers.

white-label site is one that is part of a network of sites. The likes of Race Casino and Luckland Casino are part of the L&L Group and Aspire Global groups respectively. With skins, the group holds a UKGC license and carries out many aspects of the operation such as customer support, payments and slots offering. Below is a table showing the difference between them:

Independent Site White Label Site
Unique website look and feel (design) Bigger choice of payment methods generally
Personal customer support approach More network-wide promotions
Exclusive slot game releases Greater range of self-help tools
Ability to choose slot providers/games Exclusive slots available on group level
Better welcome bonuses More emphasis on promotions/bonuses
Faster cashout times Websites tend to run smoothly 24/7

Tips for Choosing the Best UK Slots

Picking out the best place to play slots online isn’t always an easy task. You might know what themes and bonus features you prefer, but which provider supplies the best ones? Or if you’re a complete beginner, where do you even start when deciding which slot to play? Read on as we explain what to look out for depending on how often you play these games at UK online slots.

  • Slot Provider: choose a reputable provider like Play ‘n GO, NetEnt or Nolimit City
  • Theme: you should choose a game to ties into your interests (i.e. ancient Egypt or movie-themed)
  • RTP Rate: 96% is the average but be wary of different RTP versions for each online slot
  • Reels/Paylines/Mechanic: slots offer 3+ reels with millions of ways to win or Cluster/Scatter Pays
  • Bet Range: average is 10p to £50 per spin but you need to find slots which suit your pocket
  • Bonus Features: with so many, choose a game that offers extras you like such as free spins
  • Volatility: high variance slots are risky but can provide huge wins. It depends on your pocket/style of play
  • Max Win Potential: high payout online slots can pay big but come with a very small chance of winning
