How We Ranked the Best Online Slots UK

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 bonus spins that let players try out new slots for free. Some online slots sites even offer extra 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.

Why is PlayOJO the Best Site to Play Online Slots in the UK?

Among so many great UK slots sites, why did we pick PlayOJO as the best one? Hear us out.

No Wagering Requirements: No, really. There are no wagering requirements at PlayOJO. Nada. Any bonus you claim here comes with no strings attached, and you’re simply not getting this benefit at other slots sites UK.

Great Selection: PlayOJO offers over 3,000 online slot machines – a selection bigger than most online slots UK sites out there. You’ll have everything from classic slot games and jackpots to Megaways and Slingo available.

Cashback: Via the OJO Plus program, you’ll benefit from cashback with every wager you place. Even though the percentage is small, it can add up over time, and of course – the cashback has no wagering requirements.

Why Play Casino Slots Online?

Playing slots at land-based casinos while smashing the spin button and hearing people chatter will always be the superior experience – but there are quite a few areas in which online slots casinos excel.

Convenience of Playing Online Slots in the UK

We all have less time than we did before, so going out to a brick-and-mortar casino might not always be an option. Instead, you can turn on your PC or grab your mobile device and start playing UK casino slots right away – without ever having to leave your home.

Access High RTP Slots in the UK

It’s no secret that online slots have considerably higher RTPs than the ones you can find at land-based casinos. The RTP standard for online slots varies between 94% and 97%, which is a pretty good number.

The return to player percentage at land-based casinos is usually 90% – 93%, sometimes going even way below that, making the house edge unfair when you play certain games.

Explore Jackpot Slots & Games in the UK

This one might sound surprising, but the jackpot amounts at UK online slots sites are much bigger. For example, you have games like Mega Moolah with a minimum jackpot of £1 million, and then you have the likes of Snake Arena Dream Drop – with a £2 jackpot at the time of writing.

What Should I Look for in the Best UK Online Slots Sites?

No one wants to start playing at an online casino only to be scammed out of their money. Thankfully, anyone can quickly determine if a site is legitimate by looking at the following features:


While not every online casino needs to be based in the UK, they all need to be licensed and regulated by the British Gambling Commission. Almost every licensed slots site will display its licensing information at the bottom of the homepage.


Security features – like SSL encryption – have become a standard across most slots sites. Make sure to check a site’s FAQ section or contact customer support to find out what security technology they use to protect your data.

Software Suppliers:

If a site features games from reputable software suppliers, you can trust the games to be 100% fair. Companies like NetEnt, Play’n GO, and Red Tiger have a strong reputation and are staples of fairness across online casinos.

Classic slots hark back to the original, traditional slot machines that were found in casinos around the world. These are typically 3-reel slots with a simple design and gameplay, often featuring symbols such as fruits, bars, bells, and sevens.

Video Slots

Video slots are slightly different from regular slots in the sense that they have a few additional features like animations, higher-quality 3D graphics, and many different sound effects.

You can think of them as a mix of arcade games and classic fruit slot machines.

Branded UK Slots

Branded slots are types of slot machines that are based on movies, TV shows, books, video games, celebrities, and more.

One example is Microgaming’s Game of Thrones slot game based on the popular TV show in partnership with the creators of the series. Other branded UK slots include Guns N’ Roses and Hell’s Kitchen by NetEnt, The Matrix by Playtech, and more.

Jackpot Slots

There are two types of jackpot slots in the UK – fixed and progressive.

Fixed jackpots, as the name suggests, have an in-game jackpot that doesn’t change. It could be 5,000x of your initial stake, in which case, you cannot win more than that.

Progressive jackpots, on the other hand, surrender a small portion of each losing bet towards the jackpot. Because of this, the jackpot constantly rises until one lucky player wins it, in which case, it resets back to default.

Real Money Slots

Real money slots are all slot machine games that you can play for real money. All of the above-mentioned types of slots fall into this category.

Megaways Slots

Introduced by Big Time Gaming, Megaways slots are a revolutionary format that offers players potentially thousands of ways to win on each spin. This is achieved through a dynamic reel system, where the number of symbols on each reel can change with each spin, altering the number of winning combinations.
