Available Bonuses: 4.7/5
Before we go any further, you need to know that this online slots site does require a £20 minimum deposit to qualify for the first deposit bonus.
The 1st deposit bonus offers a 100% match up to £100 for UK players, which is very good considering the rollover is quite fair at 35x.

Slot Selection: 4.8/5
There are about 1,300 slot games available at All British Casino, and all of them are from leading providers like Evolution, No Limit, and Elk Studios.
There’s also a great new games list to keep the fun fresh.
For example, the provider offered UK players the chance to try the new Lordi Reel Monsters before anybody else. In simpler terms, if you have an exciting game in mind, you can be sure that it will be released on All British Casino.
We also love how you can search through the online slots by themes like music, game shows, animals and more.
Other Casino Games: 4.9/5

Pros:

Casumo is perfect for users who prefer to play slots sites on their phones. As far as user experience goes, you will not be dissatisfied with the UI, game selection, and weekly challenges.
Available Bonuses: 4.7/5
If you deposit £10 or more you’ll get 100% up to £25 plus 20 bonus spins for Sahara Riches Cash Collect. Bonus funds expire within 30 days if you fail to use them – we like how this is actually a big window comparatively.
Furthermore, you also have a couple of options to get bonuses reserved for special occasions. The Live Casino Drops & Wins promo awards £500,000 a month. They’ve also got the same for the regular casino, making it £1,000,000 in promo giveaways – that’s tough to beat.
Slot Selection: 4.8/5
Here you have approximately 2,640 games and almost 2,500 different slots.
While the sheer number of slot games won’t be topping this list, their 63 different game providers might be the most online slots developers on any single site.
Compared to other slot sites in the UK you’ll get true variety here courtesy of Microgaming, Pragmatic, Play’n GO, and many other household names.
Moreover, you will enjoy the stylistics of such classic games as Gonzo’s Quest, Pirate Pays Megaways, Vikings Go Berzerk, and other favorites.
Other Casino Games: 4.9/5
We enjoyed the combination of modern and old-fashioned when it comes to this UK casino site.
We were pleasantly surprised to discover 105 different live games. So you’re definitely not losing the real casino experience even when playing using an application.
Finally, their selection of bingo is undersized (non-existent if we’re fair). So in case you are actually searching for an application for bingo, it may not be the one for you.
Overall: 4.6/5
Casumo is a good online casino that may not have overwhelming advantages yet stands out from other slots sites with its own unique style.
What really clinches the good marks for Casumo is how it’s chiefly designed for mobile users. The ease of navigation and their slick interface lead to excellent UI across all devices. Lag won’t be taking up any time here – you can go straight to playing slots.
Click here to grab a 100% 1st deposit bonus up to £25 + 20 bonus spins at Casumo.
18+. New players only. Minimum deposit of £20. The maximum welcome bonus offer is a £50 bonus and 50 bonus spins on Book of Dead. 40x rollover on bonus money. Note that the full T&Cs apply.
Pros:
Cons:
Casushi: it’s a catchy name for an equally memorable online casino. There are a lot of things that you should know about this slot site: primarily that it’s regulated by the UK Gambling Commission and unlike other top UK casinos has their customer support locally based.
Available Bonuses: 4.7/5
Once you sign up at this online casino, you will be able to get a 100% deposit match on your first deposit up to £50.
In addition to this, you will also receive 50 extra spins to use on a famous game called the Book of Dead. The welcome package here comes with a wagering requirement of 40x.
Slot Selection: 4.8/5
Here you can find more than 1050 different games, and that’s not all.
955 of these games are online slots.
Casushi definitely keeps up with favourite slots, including Gates of Olympus, Monopoly Megaways, and the Book of the Dead. They also have great new releases, though we wish there were a separate tag to track them all down.
It seems that this website perfectly balances quantity and quality. We only wish that their interface was easier to navigate to save your time.
Other Casino Games: 4.75/5
There are many other games that you can play here too. Apart from slots, you can have fun with many different table games like blackjack, roulette, and casino poker.
We also loved the live dealer casino here which had some interesting variants like Lightening Roulette or Sweet Bonanza Candyland (a type of Wheel of Fortune).
Overall: 4.6/5
We applaud the slot selection of this online casino. Still, we wished to see more bonus options for existing players, but the 50 bonus spins and 1,000+ games is a great base here.
In all, we’ll give them extra marks as players are really raving about their customer support – at slots sites in the UK there’s something to be said for having local British service.

18+. Min deposit £20. The maximum bonus is £50 + 100 bonus spins on Book of Dead. Bonus expires after 30 days. Bonus spins valid for 48 hours. 40x wagering requirement. Note that full T&Cs apply.
Pros:
Cons:
At number four on our list of UK slots sites is FruitKings casino. Their selection of slots list may not be as plump as we’re used to, but their high RTP titles and wide selection of state of the art game providers is enough to have us biting.
Bonuses: 4.7/5
Be prepared for a 100% match up to £50 on your first deposit. That’s not all. You’re also getting 100 bonus spins on the Book of the Dead, one of the most popular online slots in the world.
There’s also a minimum deposit of £20 to claim it, which is a standard practice among most online casinos on this list.
On another note: they’ve got some amazing Drops & Wins promos with up to £1,000,000 given out every month. Half of this goes to people who play online slots, which is a huge plus.
Slot Selection: 4.8/5
There are around 1000 slot games available for you. Even though we didn’t find any original games among them, the selection is still rather impressive.
They have old-time favorites including Book of the Dead, Bonanza Megaways, and Gonzo’s Treasure Hunt (not only a high payout, but one of the best slots to extend gameplay).
We also found that this website definitely values games with high RTP. With exceptions hovering around 94%, the majority remain in a sweet spot between 95% to 97%.
Other Casino Games: 4.3/5
Even though the website mainly targets slot machines, you will also have a couple of options for roulette, including American and European versions. Users can also play blackjack and a variety of live casino games.
That said, compared to other UK slot sites we found their selection of table games to be underwhelming. It’s a very standard offering that’s low on interesting variants.
Overall: 4.6/5
With a rather narrow selection of non-slot games, Fruit Kings casino alternatively offers high RTP and 800+ video slots. In other words, this is a true slot players online casino.
You shouldn’t go any further if you want all the advantages of high RTP games.
Click here and grab a 100% deposit match up to £50 plus 100 bonus spins at FruitKings.
18+. Min deposit £10. Bonus spins are valid on the slot game “Book of Dead” and are valued at £0.10 each. Not available for North Ireland players. Note that the full T&Cs apply.
Pros:
Cons:
PlayOJO may be 5th but it isn’t far behind our top pick. With zero wagering requirements applying to its welcome offer, a very extensive game selection, and amazing mobile compatibility, PlayOJO is a fantastic selection for slot lovers.
Available Bonuses: 4.7/5
By depositing and signing up with PlayOJO, you get 50 bonus spins: £0.10 each for Book of Dead. This welcome bonus comes with zero wagering requirement, which is truly a huge advantage as it converts to cash immediately.
There are many more bonuses that this casino has to offer, mostly revolving around their OJO Wheel which awards up to 100 bonus spins at a time.
That said, since other casino sites put up cash bonuses some might dock points here for the lack of a cash 1st deposit bonus, but we’re fine with the no rollover spins quite frankly.
Slot Selection: 4.8/5
Among all our UK slot sites reviews, the selection of this particular one is the most impressive. This slot site offers more than 3200 games, 2947 of which are slots.
It is also clear that they keep up with recent updates, especially when it comes to the Megaways series. You will not have to wait anxiously for new releases. Besides, we cannot imagine anyone being bored with more than 3,000 games available.
They’ve also got a well-defined, quality progressive section with 4 million quid in jackpot slots.
Other Casino Games: 4.9/5
There are no Keno options, unlike what we see on some other sites, but it doesn’t mean that their selection is poor.
We actually immensely enjoyed all the options of online or live roulette. It seems that this site favours roulette above blackjack and poker games.
Additionally, you have at least 19 options for playing bingo if you suddenly get bored with slots. In other words, PlayOJO has the widest selection of bingo games for those needing a break from slots.
Overall: 4.6/5
We think that PlayOJO has the greatest selection of games, including slots, poker, bingo, blackjack, and roulette.
Of course, it has earned its rankings for having the lowest wagering requirements of any UK slot site – if you’re looking for a free kick at the can this is it.

Best Online Slots in the UK – Runners Up
Bonuses
We decided to start our review with bonuses. After all, you’re not using online casinos only to play. You also want to get other benefits like deposit bonus money. So we evaluated whether casinos offer unique discounts or special welcome bonuses – preferably with low rollovers.
Slot Selection
You wouldn’t want to deposit your money or even get bonuses if you have no game selection to spend it on. But we didn’t only concentrate on the number of available slots. We also tried to see whether the casino offers high RTP slots as well.
Other Casino Games
It may not be fully fair to judge online slots sites according to other games they have. However, playing online slots is best accompanied with a couple table game breaks. Naturally, we were also on the lookout for games like blackjack, roulette, casino poker, and live casino games.

After a thorough analysis of dozens of mobile slot sites, we determined that the best slots online in the UK can be found on the All British Casino website.
This website offers more than 1300 online slots games, several payment options, and quick withdrawal. They’re also fully licensed which means you can not only get their welcome deposit bonus but also trust the payouts.
We hardly think that we can choose the best slot among thousands of options. But we can tell you how to make a proper decision. When selecting slots online, you should pay attention to RTP. Serious players prefer RTPs around 96% or higher.
After considering available bonuses, selection of slots, and other casino games, we conclude that All British Casino is the best spot for playing slots online. We’ve rarely seen such a high amount of games and such a curated list of elite games providers supplying an online casino.
To be honest with you, everything depends on your online casino. If you are playing online slots at casinos that have licenses like All British Casino or PlayOJO, they have no way to cheat.
The UK gambling commission checks random number generators and mathematical models used for slots.
Therefore, casino providers must comply with rules and regulations of fair gambling. It also means that they cannot change mathematical models for demo and real games. So in case they offer an opportunity to test a game without using money, you should definitely take it.
Each game definitely has a statistical probability of users losing or winning. This probability depends on the predetermined RTP. Playing online slots with a higher RTP will have greater chances at winning.
With most slots, over millions of pulls, you can generally expect to be paid out around 95%.
