How we Select the Best UK Online Slots Casinos

That’s our ‘best of’ list, but how have we come up with it? Well, wonder no more as below we have listed the criteria by which we select the best UK online slots casino sites with excellent all-round slot gameplay.

  • Must be legit – obviously, the site must have a UKGC licence.
  • Must be generous – want to spin for tiny stakes, or are you a high roller? The site much cater for both.
  • Must have the best – we want to see top slots providers on board, such as NetEnt, Microgaming, Playtech, Play’n Go and Pragmatic Play.
  • Must have friendly bonuses – aside from a decent welcome bonus, we look for ongoing bonuses too with decent T&Cs.
  • Must be 100% for slots – when wagering, most slots contributions must be 100%.
  • Must be mobile friendly – all the slots can be played on phone and tablets, via an app or mobile browser.
  • Must be versatile – we need to see all types of slots covered from classics to those with progressive jackpots.
  • Must not be tight – we want sites to payout at speed, not at the velocity of an unconscious snail.

Our Expert Selection of the Top UK Slot Sites

We’ve gone through all the available UK casinos that have UKGC licences and evaluated them for their slotting goodness. We’ve signed up for accounts, claimed bonuses, spun the reels and contacted support. Below you will find out selections for the best online slots UK site for a number of different categories.

PlayOJO – Best Slot Casino Site for Free Spins

playojo

You can’t really get any better for free spins than PlayOJO. You can grab 80 when you sign up, and more will always be available as ‘kickers’ … but the major factor about free spins at PlayOJO is that all free spins come with zero wagering, now and forever!

Feature What We Found Our Rating
Number of Slots 2,200 4.9 / 5
Providers NetEnt, Yggdrasil, Red Tiger & more 4.8 / 5
Progressive Jackpots 240+ 4.9 / 5
Slot types Video, Progressive, Megaways 4.7 / 5

fa shield Why we chose PlayOJO:

  • Free spins with no wagering ever
  • Over 2,000 slots to choose from
  • Many top providers

Alternatives

If PlayOJO is not what you are looking for when it comes to free spins, we suggest you give Magic Red or Yeti Casino a call.

10bet – Best Megaways Slot Site

10bet casino

Megaways are slots created by BigTimeGaming and leased via other providers that have a unique feature – each reel can have between two and seven symbols per spin, upping the maximum number of paylines to 117,649! 10bet is our top bet for Megaways slots as it practically has all of them, from the first (Bonanza) to the latest!

Feature What We Found Our Rating
Number of Slots 1,200+ 4.6 / 5
Providers NetEnt, Play’n GO, Pragmatic Play & more 4.8 / 5
Progressive Jackpots 50+ 4.6 / 5
Slot types Video, Progressive, Megaways 4. 7 / 5

fa shield Why we chose 10bet:

  • Has all the Megaways slots
  • Well over 1,000 slots in total
  • Over 50 slots have progressive jackpots

Alternatives

There are plenty of sites that carry all the best Megaways slots if, for you, 10bet Casino is not doing what it says on the tin. Our other recommended Megaways sites include Fafabet and HeySpin.

Magic Red – Best Microgaming Slot Site

magic red3

If you’re a slotting expert, then no doubt you will have heard of Microgaming. They have been in the online casino business since 1997, and have produced hundreds of titles. Top Microgaming slots include Immortal Romance, Thunderstruck (I & II), Big Bad Wolf and Xcalibur, and you can play them all (and more) at the brilliant Magic Red casino.

Feature What We Found Our Rating
Number of Slots 950+ 4.4 / 5
Providers Microgaming, NetEnt, NextGen Gaming and more 4.7 / 5
Progressive Jackpots 30+ 4.4 / 5
Slot types Video, Progressive, Drops & Wins 4,6 / 5

fa shield Why we chose Magic Red:

  • Has all the best Microgaming slots
  • Free Spins with no wagering
  • Drops & Wins slots from Pragmatic Play

Alternatives

Microgaming is a ubiquitous name when it comes to slots in the UK, so there are plenty of places to play them if Magic Red is less than magic, in your opinion. Two of our top alternatives include Vegasland and ZetBet.

21LuckyBet – Best NetEnt Slot Site

21luckybet casino

Although their output hasn’t been as stellar of late, NetEnt remain on everyone’s lips when they are discussing the top slots. Despite being over a decade old, everyone still plays Starburst and Gonzo’s Quest, both absolute slotting classics. NetEnt has created dozens of top slots throughout the years, and you can play every single one of them at the brilliant 21LuckyBet.

Feature What We Found Our Rating
Number of Slots 900+ 4.4 / 5
Providers NetEnt, Microgaming, Play’n GO & more 5 / 5
Progressive Jackpots 50+ 4.6 / 5
Slot types Video, Progressive, Megaways 4.7 / 5

fa shield Why we chose 21LuckyBet:

  • Has all the best NetEnt slots
  • Huge slotting catalogue
  • Nice-looking site

Alternatives

NetEnt is even more of a ubiquitous name than Microgaming! If you are a NetEnt fan and you don’t like 21LuckyBet, then our top two alternative choices for NetEnt slots are LeoVegas and MillionPot.

Casiplay – Best Classic Slots Site

Casiplay home

Different online casinos have different interpretations of ‘classic slots’, but to us it means the kind of slots we Brits are more used to than video slots – three reels with a single payline. If you prefer traditional slots as opposed to video slots with their five reels and multiple paylines, then Casiplay is the place to visit. This long-established site has plenty of classic slots, plus a high number of video slots too, just in case you get bored!

Feature What We Found Our Rating
Number of Slots 600+ 4.2 / 5
Providers NetEnt, Pragmatic Play, Play’n GO & more 4.8 / 5
Progressive Jackpots 40+ 4.4 / 5
Slot types Classic, Video, Progressive, Megaways 5 /5

fa shield Why we chose Casiplay:

  • All types of slots available
  • Combine Drops & Wins + Megaways!
  • Always updated with the latest titles

Alternatives

You might find yourself a little stuck if you want to play classic slots (but not at Casiplay) as very few online casinos carry them these days. However, we have found two alternatives for you – Spin Rio and the All British Casino.

Winomania – Best Slot Site for Progressive Jackpots

winomania casino

Progressive jackpots are the lottery tickets of slots. You might not win that massive, rolling jackpot, but you might! Someone has to win it eventually, and you certainly won’t win it if you don’t spin progressive jackpot slots. We’ve selected Winomania as our number one choice for progressive jackpots as it can boast 15 of the very best including the number one millionaire-maker, Mega Moolah.

Feature What We Found Our Rating
Number of Slots 650+ 4.3 / 5

Why Play Online Slots?

If you have never played online slots before, then you may be asking yourself why bother? What is so ‘great’ about sitting with your laptop out, or on your phone or tablet, and endlessly spinning the reels of video ‘one armed bandits’? Well, each to their own, but we enjoy playing online slots and here are a few reasons why.

They’re Easy to Play

You don’t need an MA in Slotology to play slots. It’s just a case of hitting the spin button. Okay, so extra things will happen, but there are no rules to learn, or detailed strategies to adopt.

They are Usually Generous

As long as you pick slots with RTPs higher than 96%, your slotting funds should last you, no matter if you’re an expert slots player or not!

You Could Always Win Big!

This is the dream, isn’t it, and the reason we buy lottery tickets. When you play slots, there’s always the chance – no matter how slight – of winning that big jackpot.

You Are Spoilt for Choice!

If you get bored of one slot, there’s always the next one… then the next one… then the next one… indeed some sites have over 4,000 slots!

Casino Slot Types Explained

You can’t ever get bored with slots, and not just because there are so many of them! There are so many different kinds of slots too, so if video slots are boring you, why not try cluster pays slots, or Megaways slots, or something else! There are dozens of slots to choose in each category, and we will look through each type, right now.

Classic Slots

classic slot Different casinos can have different interpretations of classic slots, but to most, it means three-reel slots – the kind of ‘one-armed bandit’ found in seaside arcades in the UK. Classic slots are usually very easy to play, and don’t have the umpteen features associated with other, more complicated slots.

Video Slots

video slot Video slots originated in Las Vegas in 1980s following the explosion of arcade games. Instead of mechanical reels, they were computer-controlled and had a video screen. They also had more features – five reels, multiple paylines, wilds, scatters and bonus games. Video slots found their way online too, and remain the most popular type of casino slot played today.

Cluster Pays Slots

cluster payz slot If you’ve ever played a game like Candy Crush, then you’ll know all about clusters. Cluster Pays slots work in the same way. Instead of landing identical symbols on a payline, you win by landing clusters of identical symbols instead. The grids are usually large, and you have to score a large cluster in order to win. Cluster Pays slots make a welcome diversion from watching the reels and paylines.

Themed Slots

themed slot If you can think of any popular media franchise, there’s probably a slot for it. These slots use (under licence) images, music and voice-lines from the media tie-in, in order to provide a unique slotting experience. Movies, TV, reality stars, sports stars – they are all covered from The Walking Dead to Bridesmaids! If you have a top show or movie, you might just be able to play a suitably, themed slot!

Franchise Slots

franchise slot Don’t get confused about the difference between themed slots and franchise slots. Franchise slots are slots created by the same provider with a common theme, like a movie franchise or a series of books. Playtech are the kings of franchise slots, with franchises such as Age of Gods and Kingdom’s Rise. Sadly, one aspect of franchise slots – the ability to buy or win a feature on one slot to use on a different one – is not available in the UK.

Progressive Jackpots Slots

progressive slot Now we’re talking! If you want to win big, then slots with progressive jackpots are the way to go! These have jackpots that are built, little by little, by the players themselves. Multiple players across multiple online casinos will all add to the jackpot, which builds and builds until a rare symbol combination pops out, and that lucky player takes the jackpot! The current jackpot record is €19.4 million (about £16.8 million) set playing Mega Moolah at Napoleon Sports & Casino in Belgium in 2021.

Megaways Slots

megaway slot Megaways is a unique concept created by BigTimeGaming. With Megaways, slots have six reels and on each spin any reel can land with between two and seven symbols. This can raise the maximum number of paylines up to a maximum 117,649. This concept proved so successful that BTG started creating Megaways slots for other software companies who wanted to apply it to their own titles. Currently, there over 100 slots to which the Megaways concept has been applied.

How to Choose Your Next Online Slot Casino

Okay, so you know now our choices, but what if you're of the possessor of an independent spirit? If you want to go it alone, here are our tips on how you can best choose your next online slot casino.

  1. Make sure it's licensed

    This really should go without us saying again. Only play at properly licensed UKGC casinos. You are asking for trouble if you don’t.
  2. Does it have the top slots?

    If you can check out the developers at the slots site you are considering joining, then look for names such as NetEnt, Microgaming, Playtech, Play’n GO and Pragmatic Play. If those names are present, then you will have plenty of excellent slots to choose from.
  3. Happy with the payment methods?

    If you don’t want to enter your card details into the world wide web, then make sure the casino has payment alternatives you are comfortable with, such as eWallets like PayPal, Skrill and Neteller.
  4. Is support supportive enough?

    If you can, check out the support channels at the site before you sign up. If they’re unhelpful, then they aren’t likely to be of much use once you’ve become a member of the site, are they?
  5. Is the bonus fair and square?

    Don’t be swayed by a big bonus – check the T&Cs. If wagering is high (over 50x) and contributing games low, then it’s not a good bonus, and ongoing bonuses at the site are not likely to get any better.

Registering and Playing at Top UK Slot Sites

You will not experience any kind of great difficulty gaining an account at a UK slots site. Different sites have different registration methods – some involved and some simplified – but the process is generally the same across the board, and we have outlined it below.

  1. Have a look through our page and choose the site that appeals the most to you, or make your own independent selection.
  2. Hit the ‘register’ button and go through the process, accurately supplying any information that you are asked to supply.
  3. Verify your account. This is usually done by replying to an email, or a SMS.
  4. Go through any required KYC procedures. This is done for your own protection and to prevent people from opening an account using your details.
  5. Make an initial deposit. If you want to claim the welcome bonus, make sure the deposit is big enough to cover minimum deposit requirements.
  6. Get playing those top slots, as recommended by us!

Casino Slot Free Spins & Online Bonuses

Frees spins are spin on a slot that you don’t have to pay for. They are usually worth about £0.10 each, and once you have used them, your winnings probably have to be wagered before you can cash them out, although no wagering slot sites exist as well. The free casino slots spins are usually set to a specific slot too.

Deposit bonuses match a deposit at UK casino slot sites with an equal amount of bonus money that has to be wagered before you can withdraw. The best slot sites in the UK have no wagering. Slots sites no deposit bonus deals are now extremely rare – these are bonuses where you don’t have to make a deposit.

Below we have listed the best new casino sites with a free sign up bonus in terms of free or bonus spins. Check this list of slot sites to claim plenty of free spins!

Best UK Slots with Low Wagering Requirements

We always recommend that you meet wagering requirements (if applicable) for a bonus by playing a slot with a high RTP, such as over 96 percent. Always check to see the T&Cs of the offer to see if all slots contribute 100 percent. With even some of the best online casino slots sites, you may find that some slots are restricted, particularly those with high RTPs. Choose your slot once you have checked, and keep spinning. Many online casinos will allow you to keep a check on your wagering, so often there is no danger of you wagering too little, or playing for hours once you have surpassed your wagering target.

Here now are the wagering requirements needed for all the casino bonuses currently offered by our best online slots casinos, along with details of any restrictions when it comes to slots.

Play Casino Slots on Mobile

All online slots are available to play on mobile devices, be they phones or tablets, or iOS or Android powered. In the fledgling days of mobile casinos, slots used to be created using Adobe Flash, which led to compatibility issues. These days they are all created using HTML5, which means they will work on any computer-based device that’s capable of connecting to the internet.

Most mobile slot sites look identical on mobile as they do on desktops, but some may be altered slightly to look better on smaller screens. They certainly play the same way, and we have selected a trio of mobile slot sites where you can play all the leading slots on your phone or tablet with each.

Best Payout Slots for Real Money in the UK

We’ve already mentioned RTP a couple of times, and now it’s time to take a deeper look at it. The RTP of a slot is a measure of its generosity, but it’s purely a theoretical number. For example, if a slot has an RTP of 96 percent and you play 100 spins at £1 per spin with a starting balance of £100, theoretically you should have £96 remaining. However, you may have £9.60, or you may have £196, because that’s how slots work.

But! If you play the same slot with a starting balance of £100,000 and play 100,000 spins at £1 per spin, you will probably end up with a balance close to £96,000. The longer you play a slot, the more likely it is to payout at its RTP slot.

RTP is not something you should worry about but you should choose slots with high RTPs over ones with low ones as it just makes sense. Here are ten of the highest RTP slots currently available in the UK.

Slot RTP (%) Developer Play Here
Book of 99 99.00 Relax Gaming PlayOJO
1492: Uncharted Seas 98.60 Thunderkick MrQ
Blood Suckers 98.00 NetEnt 21LuckyBet
