WHY PLAY AT UK SLOT SITES?
The huge variety of video slots ensures that they remain the most popular casino game. Therefore, so many online casinos in the UK label themselves as specialist online slot sites.
However, you must consider lots of aspects when picking a slot 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 sites 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 UK slot sites listed on this page.
We guarantee that all of the online slot 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 slot players.

- Selection of Online Slots – There are thousands of online slots in the UK, all with varying themes, RTP percentages and ways to win.

VARIATIONS OF ONLINE SLOTS UK
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 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 Gonzo’s Quest, Immortal Romance and Da Vinci Diamonds.
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 get their name from the jackpots they payout. These slots can eventually payout hundreds of thousands and even millions of pounds.
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.
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.

SLOTS BONUSES AND OFFERS

If you are searching for a particular bonus related to slots, all of the slot sites 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.

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. The newest handheld devices are often superior to their desktop counterparts.
See our list of mobile slot sites for casinos performing particularly well in this area.
FAST PAYOUT SLOT SITES

At SlotsHawk, we have all of the information you need on the fastest payout slot sites and casinos in the UK.
£5 DEPOSIT SLOTS SITES
Although most UK slot sites require you to make a deposit of at least £10 or £20, there are some that allow players to deposit £5.
£5 deposit casinos and slot sites are rare as most slot sites online 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 UK Gambling Commission (UKGC), there are plenty of other methods.
UK SLOT SITES FAQS
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 best UK slot sites 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 slot sites 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.
