FIND AND PLAY AT UK SLOT SITES

The huge variety of video slots ensures that they remain the most popular casino game. Many online casinos in the UK label themselves as specialist online slot sites. However, you must consider lots of aspects when picking a site to play on.

Factors such as choice of games, available deposit and withdrawal options, promotions for loyal players and finally, which casino you think will give you the best gaming experience. But before you decide any of this, please check that the online slot site you have set your eyes on is fully registered and licensed.

All slot websites operating in the UK must apply for and then receive an operating license from the UK Gambling Commission (UKGC). The UKGC is the UK gambling watchdog that protects players from potential rogue and unlawful operators.

You will find the best UK slot games at the online casinos listed on this page. We guarantee that all of the sites listed here and across the entire SlotsHawk website are fully licensed and regulated.

This means that they are able to operate in the UK. Our list of new slot sites are also fully regulated and safe to play at. UK slot sites always accept players from the UK and sometimes players from other countries – this makes them a superb choice for many players.

TRUSTED AND UKGC LICENSED UK SLOT SITES

All of the online casinos featured on this page have received a license to operate in the United Kingdom from the UK Gambling Commission.

In order to receive a license, operators must go through a vigorous and thorough process to prove to the UK Gambling watchdog that they offer safe and fair games of chance to UK gamblers. In addition, gambling operators must prove that they have sufficient site security to protect their players from unscrupulous characters and hackers. Finally, the sites must provide their players with safe and reliable payment options for making casino deposit and withdrawals.

All slot websites must also adhere to responsible gambling regulations and must ensure that their players are regularly and routinely given safety checks to ensure that they are still in control of their gambling habits.

Each and every online casino hosting slot games at SlotsHawk has a license from the UKGC.

HOW WE DECIDE OUR RANKINGS

best slot ssites

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 the best British casinos and we do not rank sites 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 customers offers, 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 bonus redeemable?
  • Site usability, reliability and mobile friendliness – Are 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 are the customer support team at the slot site in the UK? 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?

ONLINE SLOTS

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 top UK slots can be arranged 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 UK 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 offer exciting features such as wilds and scatter symbols as well as heart-pumping bonus rounds.

Some of our favourite video slots of 2021 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. The best slots sites will stock branded slot games. 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 of 2021 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 offers players one of the highest RTP percentages.

OUR PICK OF THE TOP 10 REAL MONEY ONLINE SLOTS TO PLAY IN DECEMBER 2021

  2. Punk Rocker – by NoLimit City
  3. Book of Dead – by Play N Go
  4. Aloha Cluster Pays – by NetEnt

  6. Immortal Romance – by Microgaming
  7. Gonzo’s Quest Megaways – by NetEnt
  8. Genie Jackpots Megaways – by Blueprint Gaming
  9. Razor Shark – by Push Gaming
  10. Mystery Fruit – by Red Tiger Gaming

SLOTS BONUSES AND OFFERS AT THE TOP ONLINE SLOT SITES

The best sites always offer casino bonuses specific to their players. UK slot websites are particularly generous. Bonus spins are used to entice players to make a deposit or sign up. 

If you are searching for a particular bonus related to slots, all of the online casinos offering slots listed on this page will give you some form of slots bonus – it is up to you to pick and choose which one appeals to you the most.

For example, one site may offer a 100% welcome bonus of up to £400 which can give you a starting bankroll of £800. Deposit £400 of your own money and the slot site will give you an additional £400.

On the other hand, another site may offer you a 100% bonus of up to £100 plus 50 bonus spins. This will give you a potential bankroll of £200 as well as 50 bonus spins if you deposit £100 of your own money.

Or perhaps you want to play without depositing any of your own money, in that case you should search our site for a no deposit bonus. A no deposit bonus casino will give you a small amount of money to play with just for signing up. Be aware though that these bonuses often come with wagering requirements.

Below you can find the top selection of slots bonuses available in the UK. To find more offers, check out our slots bonus page.

SLOTSHAWK TOP TIPS FOR CHOOSING TRUSTWORTHY SLOT SITES

Below, you will find a detailed list of the different types of casinos online in the UK.

STARBURST SITES

Play Starburst at Slot sites in the UK

As one of the most popular video slot games ever Starburst is a must have for all serious UK gambling sites online. What makes Starburst stand out is that you often can get promotional offers like no deposit free spins and reload bonuses on the game.

It is also a simple and entertaining slot machine for both new players and more experienced slots enthusiasts. Don’t forget, for the reasons above, we have created a dedicated page for Starburst sites.

TRY SOMETHING DIFFERENT – SLINGO SITES AND GAMES

If you like to play online slots, but also like to play online bingo, then you will definitely love Slingo.

Slingo is a mix between slots and bingo, and the the London based company Gaming Realms holds the license for this unique game mechanic.

Therefore, only certain casinos play host to Slingo games on their platform. We have listed them at our Slingo Sites page.

UK MOBILE SLOT SITES

The leading and best casinos offer players the opportunity to play online slots on their mobile devices.

Most casino slot sites are marked up with HTML5. This allows slot games to run just as smooth on a mobile phone as they would on a desktop computer or laptop.

In fact, the best slots sites UK now have a mobile-first strategy – ensuring mobile users are satisfied before desktop users.

Over half of slot players play via their mobile phones or tablet devices.

Stephen Cummings on the best slot sites

“I love playing slot games on my mobile because it offers me 100% convenience.”

– Stephen Cummings, Slots Analyst.

We do not need to explain the convenience of playing online slots on your mobile phone. You can play your favourite video slots whilst sitting on your living room sofa, in the local café, on your lunch break or traveling on a bus or train.

Mobile slots will work on most modern mobile phones and tablet devices. Obviously, if you are still knocking about with a Nokia 3310 then you won’t be able to play.

All modern iPhones and Android devices, on the other hand, are perfectly capable of running casino gaming software with handheld devices often superior to their desktop counterparts. See our list of mobile slot sites for casinos performing particularly well in this area.

FAST PAYOUT SITES

For many casino players, one important characteristic of a good slot site is how quickly it pays out withdrawals. No player wants to wait days or even weeks for their winnings to hit their bank account.

More often than not, these casinos will offer players the opportunity to make withdrawals using eWallets. It is eWallets that are known for their safety and instant casino withdrawals and deposits.

At SlotsHawk, we have all of the information you need on the fastest payout slot sites and casinos in the UK.

£5 DEPOSIT SITES

£5 deposit slot sites

Although most UK casinos require you to make a deposit of at least £10 or £20, there are some that allow players to deposit £5.

£5 deposit casinos are rare as most operators prefer their players to make larger deposits. However, SlotsHawk have scoured the UK casino market and have found several £5 deposit slot websites.

See our list of £5 deposit slots sites for casinos which are accepting deposits of £5.

SLOT SITE CASHIER OPTIONS

There are lots of different ways to withdraw and deposit into your online slots site account. Although credit card gambling has been banned by the UKGC, there are plenty of other methods.

We recommend eWallet’s like PayPal. PayPal is a global brand and is one of the safest casino withdrawal and deposit options. There are also plenty of PayPal slot sites for you to pick from as well as Pay by Phone slot sites and Paysafecard casinos.

UK SLOT SITES FAQS

1. Which is the best UK online slot site for winning?

The best slot sites in the UK will have a wide range of different online slots for their customers to play. They should have a catalogue of slot games from a variety of online slot providers and be able to offer customers different types of online slots from jackpot slots to video slots. The casinos will also treat their customers to lots of slots bonuses including bonuses for signing up and bonuses for playing at their casino. They should also offer several different payment options and a 24/7 customer support team in case their players have any issues.


2. Are UK slot sites safe to play at?

No, not all slot sites in the UK are safe for you to play at. However, the slot sites listed at SlotsHawk are 100% safe and fair. All the casinos we list have been thoroughly reviewed by not only us but also the UK Gambling Commission. If you are unsure whether a UK slot site is safe, scroll to the bottom and look out for the UKGC stamp of approval.


3. Which slot site offers the best odds?

Slots odds are not fixed. They are determined by their Return To Player (RTP) percentage which shows how much money will be paid back compared to the amount wagered. For example, a slot with 94% RTP will, on average, pay back £94 for every £100 wagered. This is of course theoretical and will change from session to session. If you are looking for a slot site offering the best odds, you should find the games with the highest RTP and head over to a casino that offers the game.


4. Can you win money playing online slots?

Yes, it is possible to win real money playing at licensed UK online casinos, but this means that you can also lose money. Most slots offer players the chance to play for as little as 10p per spin up to £100 per spin. For example, if you deposit £50 and you spin the reels on a slot and win £25 from a £1 spin, you will be able to withdraw your winnings back onto your debit card or other payment method you deposited with.


5. Can I play slots online for free?

It is possible to play slots for free, but you will first need to register at an online casino that is able to offer free-to-play slot games. In May 2019, the UKGC ruled that you had to be registered to an online casino before you could be allowed to play any form of slot games online. This ruling came into place to ensure that under 18s were prevented from experiencing slot play. Anyone registering to an online casino will have their age verified.


6. What kind of slot offers the biggest wins?

Progressive jackpot slots offer the largest potential wins. Top slot sites can generate huge jackpots as a small portion of each player’s stake will contribute to the jackpot. This jackpot will continue rising until one lucky player triggers a win and scoops the lot. Progressive jackpot slots can payout jackpots of over £1 million.


7. Where can I play progressive jackpot slots?

Progressive jackpot slots are offered by most online casinos. Some of them offer small prizes and are triggered weekly while others offer huge prizes which pay out rarely but when they do the jackpots can be life changing sums. We recommend Mega Moolah; this is one of the most popular progressive jackpot slots to play in the UK.


8. Can I play online slots on my mobile?

Over 50% of slot players play via their mobile phone. HTML5 technology is used by game developers which ensures that their products are optimised for all devices. Slot games are now developed for mobile first. Developers and software providers will first work to ensure their game is fully optimised for a mobile device.


9. What is the best online slots site?

This depends on exactly what characteristics you are looking for in an online slots site. Find our list of the top slot sites in the UK at SlotsHawk.
