UK players have thousands of real money online slots to choose from with amazing graphics, bonus rounds, and some of the biggest jackpots.

But with so much variety, it can be hard to know which are the best online slots in the UK – the ones with the biggest payouts and RTP rates.

Luckily, we’ve done all the research for you and updated our list with the top slots sites available in the UK right now – with PlayOJO at the top of our list thanks to its massive selection of 3,000+ slots and no-wagering-requirements approach.

That said, we found many other online casinos offering top-tier slots, so let’s check them out.

Best Online Slots in the UK

PlayOJO (Big Bass Bonanza): Best slots overall
Grosvenor (Fishin’ Frenzy): Highest RTPs
Casumo (Buffalo Blitz): Biggest slots variety
Luckland (Book of Dead): Best mobile slots
LeoVegas (Starburst): Best welcome bonus
Magic Red (Wolf Gold): Top pick for classic slots
The Sun Vegas (Age of the Gods: God of Storms): Best for jackpots

PlayOJO (Big Bass Bonanza)

New, 18+ players only. First deposit only. 50 Free Spins on the Book of Dead slot. Free Spin valued at £0.10. No wagering requirements. Note that full T&Cs apply.

Pros:

— 3,000 slots from about 60 software providers

PlayOJO is the king for today and the best slots site for UK players – bar none. This platform sports a recognisable yet very light design, loaded with 3,000 titles from the leading software studios.

Best Slot Machine: Big Bass Bonanza

This 5-reel, 3-row slot machine allows you to win big through a highly volatile game of luck with a higher-than-average RTP of over 96.5%. To help you catch the fish and make the journey more exciting, the game throws a variety of special goodies along the way, offering an x2,100 winning potential.

Quality of Slot Games: 5/5

PlayOJO is home to about 3,000 slot machines from around 60 software providers. Apart from Big Bass Bonanza, we think that UK players shouldn’t miss the Miss Wildfire game and Rainbow Riches Race Day for high, 96%+ RTPs, or Eye Of Horus and Fishin’ Frenzy for massive 7-figure jackpots.

Some of the game studios on the site include Playtech, Play N’ Go, Pragmatic Play, Red Tiger, and many more.

Bonuses: 4.8/5

New players are eligible to claim 50 bonus spins on the Book of Dead slot game – with no wagering requirements!

Just meet the minimum deposit requirement – which is £10 – on your first deposit, and the spins will slide into your casino account. Also, the winnings from these spins are not capped. If you manage to land the biggest-paying combination, you’ll keep all of your winnings.

Payment Options: 4.6/5

The payment options at PlayOJO are pretty decent. There are only 5, but most UK players should be able to use them.

You can use Visa, MasterCard, Trustly, PayPal, and bank transfers. PayPal is the fastest option, and you’ll usually see the money in your account within a day after submitting a payout request, while bank transfers can take as much as a full week.

Mobile Design & Customer Support: 5/5

We like how the devs managed to give PlayOJO a striking design while keeping the website as lightweight as possible.

No complicated animations here, just a mixture of bright colours and a distinctive design. All pages load fast, and every slot machine we tested worked like a charm.

You can contact the support representatives using live chat or by dropping them an email. We recommend checking the FAQs first, but once you reach out, you can rest assured that your inquiry will be addressed in a matter of minutes if you use the live chat function.

Casumo is optimised for iOS and Android mobile devices, and all the features from the desktop version are readily available to mobile users. The site also has its own blog and is active on Facebook and Twitter.

Quality of Slot Games: 4.5/5

LeoVegas offers a decent selection of games, with well over 1,000 titles from 30 game studios. It packs many of the classic slots that made their mark in the online gambling industry throughout the years.

As a new customer on LeoVegas, you are eligible to claim up to £100 and 50 bonus spins. You need to claim the promo within 7 days and meet the 35x wagering requirements before becoming eligible to withdraw the bonus winnings.

The promo is split into two equal parts that cover the first two deposits you make on the site. The spins are added to the Big Bass Splash slot game – 25 spins per deposit, with 3-day expiry.

LeoVegas regularly updates its promos, so make sure to check back every once in a while for the latest deals.

Payment Options: 4.1/5

The payment section at LeoVegas is easy to navigate, but the list of available options leaves a lot to be desired.

You can use Visa Debit, Visa Electron, wire transfers, and PayPal. We really appreciate the addition of PayPal and recommend it as the fastest option.

LeoVegas sports a decent design, although it could be aesthetically improved. The platform is still safe and SSL encrypted – so, no major flaws here. The site works just fine on iOS and Android devices, and you can either play via your browser or download a casino app.

You can reach out to the support agents using the on-site live chat or drop them an email if the matter isn’t that urgent. They’ll reply within a day in that case.

6. Magic Red (Wolf Gold): Best for Classic Online Slots in the UK

Magic Red (Wolf Gold)

— Over 700 slots
— Popular branded games
— Weekly free spins

Magic Red immediately impressed us with its collection of over 700 slots. From popular titles like Book of Dead to famous branded games like Game of Thrones, the slots page has enough variety for everyone to find something to enjoy.

Players can also earn free spins through the welcome bonus, and weekly Magic Spins Tuesday promotion. While the amount of spins isn’t huge, and they can only be used on Starburst, they still let you enjoy the thrills of slots for free.

NetEnt, Red Tiger, and QuickSpins are just a few of the many reputable software suppliers featured on the site. This ensures you can find fair games that utilise the latest gaming technology. There are also loads of deposit methods to pick from, including various e-wallets, cards, and bank transfers, so you can always find a convenient option for you.

Ranking Methodology for the Best Slots Sites UK Players Can Sign Up to

Variety of Slots

Not everyone enjoys playing the same type of game repeatedly, which is why there are so many types of slots.

A top slot site should offer many ways to play, from unpredictable Megaways’ titles to high-risk, high-reward jackpot slots. Branded games are another huge draw, letting you enjoy your favourite franchises in slot form.

Slot Bonuses

Even the most valuable bonuses won’t appeal to slots fans if they don’t apply to slots.

So, we always check the promotions page for bonuses like regular free spins that let players try out new slots for free. Some sites even offer free spins as part of their welcome package. Slots tournaments are another standard promotion that lets you compete with other like-minded players for impressive prizes.

Quality of Software Suppliers

Most online casinos offer hundreds – or even thousands – of slots, and the quality can vary dramatically depending on the supplier.

It’s always important to check which studios are featured on the site. Companies like NetEnt and Microgaming have developed many world-renowned slots and are good indicators of a high-quality game selection.

Payment Methods

Many slots feature fast-paced gameplay where anything can happen, and players will want fast and convenient banking options to top up their accounts quickly.

A good slot casino should accept a diverse range of payment methods and process transactions almost instantly. Withdrawals should also be fast so you can get your winnings reasonably quickly.
