Best Online Slots Sites in the UK
So, you now know our list of the best online slots sites that are available in the UK. You may though be scratching your head wondering as to how we have come up with ‘the’ definitive list. Why did some online slots sites make the ‘top of the best online slots UK sites’ list while others have been told to get stuffed? Even then, why are some sites getting nosebleeds at the top of our list while others are feeling the pressure of those online slots sites listed above them?
Well, wonder no more are we are here to enlighten you about the slot sites factors we think about when coming up with our top list.
- Quality of Games – There are now thousands of slots a slotting site has to choose from when deciding upon their wares. We are very much ‘in the know’ about slots so we can tell if a site is bulking up its numbers with plenty of feeble, low-quality titles. The best slots sites UK have the best slots – it really is that simple.
- Variety of Games – There are plenty of different types of slots, and we like to see a site that can offer a decent variety of them. There’s pub slots, video slots, ‘Megaways Slots’, slots with progressive jackpots … it really is a very long list. We love a site that offers a little bit of everything, so such a site will make our list of the best slots sites UK.
- Promotions & Bonuses – Most sites will offer you a bonus, which can only be a good thing, surely? Well, not all bonuses are made the same, so we like bonuses that have fair and square terms and conditions. We also like to see sites that offer bonuses on a regular basis, and not just as an incentive for new players.
- Not Just Slots! – Okay, so there are a few people out there who play the best casino slots and nothing else, but we prefer online slots sites suited to people who like a little bit of everything. Most slots sites will have a few casino games too such as blackjack and roulette, plus less common games and even sports betting. A live casino is pretty much a ‘must have’ these days too.
- Payment Methods – You should not have too many issues in the UK in getting money into your online casino account, as nearly all of them take debit cards. If you want an alternative then things toughen up more than a little. With credit cards now off the table, we like to see sites that offer many alternatives, including eWallets, eVouchers and even cryptocurrencies.
- Support – Let’s hope you never have to use support at an online casino, but the best sites for slots have support options available should you need them. We’re mainly talking about live chat support of course, not an unmanned email inbox. Telephone support is always good, too.
- Safety – If you are in the UK then you will need to be playing at a site with the proper UKGC licensing. You can rest assured that all the sites mentioned anywhere on this site in terms of UK gambling have a UKGC licence. You are perfectly safe at any site that has one.
- Responsible Gambling – All slots sites in the UK have a responsibilty towards their players and that resposibility includes the promotion of responsible gambling. All the best sites for slots are those that take their responsibilities towards the well-being of their players very seriously indeed.

Why Play Online Slots?
The number one reason why people play online slots is because they find them entertaining, with the chance of winning money a very close second. There are a great many online slots available meaning that is hard to get bored with them, plus there are brand new slots released every week.
The second attraction is the prospect of winning money. You are unlikely to get rich playing online slots unless you score a progressive jackpot, but with steady play and a decent string of good fortune, you’ll probably end up winning more money than you lose in the long term.
The simplicity of slots is another bonus. You don’t have to learn rules or play forever to return a profit as you can just watch the reels spin. There is barely any decision-making to do at all, aside perhaps from the odd bonus game.
There are of course reasons not to play online slots, and that’s if you are playing them with the intention of them becoming your regular source of income. No one has ever successfully done such a thing, and we honestly think that you are not likely to be the first!
Online Slots Variation
Slots have developed in an incredible fashion since they were created well over a century ago! They were originally designed to simulate poker hands but they have certainly moved on a great deal since then. Here are details about the most common variants of slots found at online slots sites and casinos in the UK. You will find them at the best UK online slots sites, the best betting sites for slots and the best bingo sites with slots.
A ‘classic’ slot can mean a lot of things, but generally in the UK it means a slot that is designed around the ‘one-armed bandit’ design with three reels and a single, central pay line. These are the easiest slots you can play but because of the lack of action, they are not the most popular.
Many online slots and casino sites will have a small number of ‘classic slots’ available. Only a few online software developers though – such as Swedish company Play’n GO – actively create new classic slots with three reels and a minimum number of paylines. If you like the sound of classic slots, then we happen to think that William Hill is the best place to play them at.
Video Slots were the next step up from mechanical slots. Inspired by the arcade video game boom, slots developers replaced the mechanical parts of their slots with video screens and computer chips. These computer-controlled slots could add much more than the simple spinning of the reels, including wilds, scatters and bonus games.
Once the internet invaded our lives it was only a matter of time before software versions of video slots appeared online. They started in the late 1990s and have been the mainstay of the slotting world every since, becoming more and more feature-rich as time has marched on. For the best video slots available in the UK, visit Kwiff.
In 2011 famed Swedish slots developers NetEnt released a slot called ‘Gonzo’s Quest’. This game stunned the slotting world with its incredible graphics and gameplay, as well as being the first to use the ‘avalanche’ feature. When triggered, winning symbols would cascade down from the reels and new ones would fall in from above to replace them. Slotting fans went a little nuts over this feature.
There have now been many dozens of slots released that use the ‘avalanche’ or ‘cascade’ feature. Some link it to a progressive feature where the rewards getting better with the number of successive avalanche wins you achieve. Everything sets back to zero though once your run of avalanche wins comes to an end. Choose PlayOJO for plenty of avalance slots opportunities.
Progressive Jackpot Slots
You may think that progressive jackpot slots are a new phenomenom, but you’d be wrong in thinking that. Such slots have been around in real world casinos since the 1970s. Back then, they were radio-linked, so the details of one linked slot could be shared with all the others on the network.
With such slots a tiny percentage of each wager paid into all linked slots is held back and contributes to a rolling jackpot – just like a lottery. When anyone playing any of the linked slots lands a specific, rare combination of symbols then the jackpot is triggered, and the lucky player suddenly finds themselves fabulously rich!
Online progressive slots work in the same way as real-world progressive slots except that they are linked over the internet, and not via radio waves! Several lucky peeps have become millionaires thanks to progressive jackpot slots, so if you play them at 2kBet (or anywhere else), you could join that list!
All Ways Pay Slots
Prior to the introduction of video slots, it was common for slots to have a single payline, right across the middle. Video slots introduced the concept of multiple paylines – weird ‘lines’ in which if identical symbols fell into, they would win just as much as a the classic middle line. With a slot that has five reels and three rows the maximum number of potential paylines is 243, and that’s basically what ‘all ways pay’ slots are all about.
Such slots do not bother with paylines – as long as you land successive identical symbols (usually with a three-symbol minimum) on the reels starting from and including the left-hand reel, then you are a winner! Of course the more reels and rows an ‘all ways pay’ slot has, the more chances you have of winning. Check out LuckLand for plenty of all ways pay slots.
The software company Big Time Gaming had a big time idea in 2016 when they took their bang average Bonanza slot and applied an update they called ‘Megaways’ to it. They upped the number of reels to six, made it ‘all ways pay’ and allowed each reel on each spin to have between two and seven reels. This resulting in an online slot that could max out at an incredible 117,649 paylines!
Soon Bonanza Megaways became BTG’s most popular slot and so they applied the ‘Megaways’ concept to other slots in their range. Plenty of other developers loved what was happening with Megaways and asked BTG if they could apply Megaways to their own slots – BTG said yes as long as you pay us some money!
There are now over 100 Megaways slots available from multiple developers, with even classic slots such as Gonzo’s Quest getting in on the act. If you want to sample a few Megaways online slots, we feel that Betfred would be a good place to start.
Cluster Pays Slots
There’s an argument that so-called ‘cluster pays’ slots are not slots at all. They don’t have reels or paylines for a start, although they do offer something a little different at least. With such slots you land wins by landing clusters of identical symbols – where they touch either vertically or horizontally. As long as your cluster contains the minimum number of winners, then you win!
When a winning cluster is triggered, the winning symbols usually vamoosh from the reels to be replaced by news ones. This can of course trigger new wins, and exciting new features! If no wins land then the entire grid drops away allowing a complete new set of symbols in to take their place. If you want to see what cluster pays slots can offer you, then given BritainBet a try.
How to Play Online Slots
Online slots do look a little confusing at first, especially if you have been brought up in the UK with one-armed bandits as opposed to the video slots of Las Vegas. To help you get started with online slots, we are going to walk you through a couple of spins of NetEnt’s celebrated title Starburst, as this slot is very entertaining yet very easy to play.
Above you can see the typical Starburst startup screen. This classic slot has five reels, three rows and ten paylines, although there is a twist. This slot’s paylines run from both left to right (as normal) but right to left as well, doubling your chances of landing a win.
At the moment, the value of our coin/bet is 20p. Because there are ten paylines, we pay ten coins for a total of £2.00. If you want to bet more you can increase the bet level up to a maximum of five, although here we have it set at one. We’ve only £3.22 in the bank, so we are not going to get much spinning done at two quid per spin so we need to decrease our coin value.
By using the options available our coin value is now only 1p. As our bet level is still one, we are betting ten coins per spin, for a total bet of 10p. Now it’s time to hit the spin button!
We did a spin but we did not win. There are plenty of high-value sevens around but as they did not fall on a payline we didn’t win a bean. So, it’s time to hit the spin button again.
It takes a couple of spins but finally we get our first win. We land three orange gem symbols on payline number five, running right to left. This is worth seven coins to us, so as our coin size is one penny, we win seven pence … so we won’t be able to retire just yet.
The maximum payout that’s available via Starburst is 50,000 coins, so with our one penny bet we could win £500. Of course, if you increase your coin size you could win a whole lot more!
All slots have their own different nuances and rules and ways of playing. Before you play any slot it’s always best to have a look through the playing rules, but as soon as you’ve mastered a few slots you usually become the master of them all!
New Online Slots Sites UK
You would have thought the slots and online casino market in the UK would have reached saturation point by now, but that doesn’t stop new sites springing up, seemingly on a daily basis! Many new sites also seem to vanish overnight, but some newbs turn out to be around for the long haul.
New sites are always good to find from the perspective of the seasoned online slots player. They usually offer good deals for new players, so there’s something of value for anyone who signs on the online casino dotted line. In addition, there is always the chance you’ll find a brand new site that ticks all your boxes for slots and casino play.

Online Developers – Makers of the Best Slots Online
Some new best slot casinos and slot sites players get a little confused when they see the same slot at a number of different online slots casinos. That’s because online casinos do not make their own games … okay, some do (888) but most rely upon third party developers to make the slots for them. They sign deals with the developers to allow them to use the slots at their site, or with an aggregator company like EveryMatrix which has deals with dozens of developers. A slots site can fill itself with online games by just signing a single deal.
Below you will find information about the leading slots developers whose titles are usually found at UK slots and casino sites.
We don’t have time to count them all, but we reckon there are now at least three hundred slots development companies available globally. Of course, some are much better than others, so in addition to the four names above, here are a few developers whose output we think you should be looking out for.
- Big Time Gaming
- Blueprint Gaming
- Pragmatic Play
- Red Tiger
- Relax Gaming
Online Slot Bonuses and Free Spins
One common factor across the board at slots and casino sites is that when you sign up for a site, you’re given a welcome bonus. Most bonuses are pretty decent deals, but a few hide clauses in the T&Cs that render your bonus almost worthless.
So that you understand a little more about bonuses, we have put together a quick guide outlining the most common types of bonuses available, what you can expect from them, and what else you need to look out for.
The most common welcome bonus at the best UK slots sites is usually in the form ‘deposit £x to get x% bonus’. This means that if the maximum deposit amount is £100 and the percentage 100 percent, then a deposit of £50 will earn you £50 in bonus money. You might not have to deposit £100 to get the bonus though – some of the best bonus slots deals will reward you for deposits as low as £10. All you need to do is check the T&Cs to see the lower and upper limits for a bonus.
Free spins (or bonus spins as they are also commonly called) are free spins that you receive when you sign up with a site. They are commonly tied to a specific slot, although sometimes you may be able to use them on a range of slots or any slot at the site. Winnings from your free spins can sometimes be cashed out immediately, but more often than not are subject to wagering requirements.
Wagering requirements confuse many people, but they are not too difficult to get your head around. Say a deal comes with a wagering requirement of ’25 x deposit and bonus’ and your bonus is £100, then your wagering is 25 x (£100 deposit + £100 bonus) = £5,000. This means you have to wager £5,000 of your own money before you can make a withdrawal. The same principle applies to free spins winnings with wagering requirements.
Not all games with contribute the same towards wagering. Slots usually count 100 percent, so if you wager £1 on a slot and have £100 of wagering to get through, then after that wager you’d have £99 of wagering left. Blackjack that might only make a 10 percent contribution, so a £1 wager will only take £0.10 off of your wagering. Always check the T&Cs of any bonus offer to see the game contribution clauses it contains.
All bonus offers come with limits. You will have a limited time to claim your bonus, a limited time to use your bonus, and finally a limited time to meet your wagering requirements.
Winnings may be capped as well. For example if a bonus has an upper winnings ceiling of £50 and you win £100, then £50 of those winnings will be forfeited.

Best Online Casino Slots with High RTPs
The ‘return to player’, or RTP for short, is the theorectical percentage of funds a slot player would have remaining after a (very) long playing session using a specific slot. For example, if a slot has an RTP of 96 percent, then a player with £100 playing £0.01 per spin after 10,000 spins would have – theorectically at least – £96 remaining.
Of course this never works out in practice as even the best payout online slots UK are notoriously volatile, prone to more losses than wins over a short period, and vice versa. The RTP of a slot is though a good measure of the slot’s generosity, and you should only ever play slots with RTPs around or over 96%.
Below are the best slots online that are commonly available around casino land with the highest RTPs. You will find these at all the best payout slots sites. These are not the very best payout online slots ever made, but they are the ones most commonly found at the best online slots sites in the UK.
|1429 Uncharted Seas||Thunderkick||98.6%||888casino|
|Dead or Alive||NetEnt||96.8%||BetUK|
|Thunderstruck II||Microgaming||96.7%||Play OJO|
|Rich Wilde & the Book of Dead||Play’n GO||96.2%||Kwiff|
Of all the many types of casino games, slots are perhaps the easiest to render for mobile devices. In fact all slots, when released, are tested to make sure they work well on iOS and Android-powered phones and tablets.
In days gone by online slots used to run on Adobe’s Flash platform, but in around 2016 they began to move to HTML5 – which is a good job as Flash has now been taken out of circulation. If you prefer to play mobile as opposed to via a laptop or desktop PC, then you should find zero problems when playing the best mobile slots on your phone or tablet. All of the best online casino slots work perfectly well on mobile.
