With more than 6,200 slots on offer, Videoslots’ game offering can’t be beaten. When I also factored in the 11 wager-free spins, an enticing welcome offer, and 35x wagering requirements for all non-jackpot slots, and it’s easy to see why Videoslots comes out on top for me.

Mr Vegas - The Most Jackpot Slots

Another casino with a massive library, Mr Vegas has made a remarkable impression since its 2020 launch. When it comes to online slot games, Mr Vegas is one of the best casinos around.

Having almost 5,500 slot games to offer is absolutely amazing by any standard. The best part for me is that Mr Vegas offers an extensive selection of more than 500 fixed, progressive or daily jackpot slot games to choose from! As a lover of jackpot slots, it was hard for me to not get excited.

Pokerstars - All Round Excellence

Pokerstars is an exemplary online casino, and one of the leaders in the industry. As well as having a world-class live casino and table game offering, Pokerstars also has an outstanding slot game offering.

I was impressed with every aspect of Pokerstars’ slots offering. The game total is outstanding, containing some Pokerstars-exclusive slots. Receiving 250 free spins is incredibly generous, and they can be used on a wide range of slots!

Playzee - Lots of Free Spins, Lots of Slots

Playzee has consistently been a CasinoRange favourite since it debuted in 2018. The White Hat Gaming outfit has a stacked roster of online slots for players to sink their teeth into.

I feel that Playzee have struck a great balance between their slots offering and their welcome offer. The game selection is incredibly solid, reaching close to the 2,000 mark, while I found 100 free spins to be incredibly generous. The only drawback is that the free spins have to be used on Starburst only, even if that is one of my favourite slot games!

Jackpot Village - Dedication to Slots

Jackpot Village has been a top online casino since 2019. Boasting a stellar reputation and an amazing selection of games, Jackpot Village brings a lot to the slots table.

Jackpot Village is another casino with an impressive library of slots, breaking the 2,000 barrier. I was struck by Jackpot Village’s sheer dedication to slots; there are 2,269 slot games compared to 57 live casino games and 67 table games - slots are clearly the priority!

Grosvenor Casinos - Exclusive Slots and Low Wagering Requirements

One of the most trusted brands you’ll come across, Grosvenor Casinos’ land-based experience has translated well to the world of online casinos - especially the world of online slots.

Although other casinos on this list have higher game counts (894 slots is still respectable), I thought that Grosvenor Casinos had some strong selling points. Firstly, Grosvenor has exclusive slot games to play which help differentiate them from the majority of online casinos. Furthermore, the welcome bonus comes with a 5x wagering requirement - one of the lowest you’ll come across.

Best Slot Bonus Offers

As online slots are usually the most popular game in an online casino’s library, their welcome offers usually reflect this and are weighted towards free spins. A good welcome offer for online slot games has a decent number of free spins to be used, or failing that, bonus funds that can be used for slots. Ideally, the free spins can be used on multiple slot games, and the wagering requirements should be as low as possible. Here are some of the best bonus offers you’ll find for online slots at UK casinos:

How Do We Rank The Best Slot Sites?

What do we look for when assessing a slot casino? Here are some of the factors that affect our selections.

Slot Game Selection

You’re looking for the best slot casino, so the number of slot games on offer is clearly an important factor. We look at the quantity and quality on offer, as well as the different providers supplying the games.

Bonus Compatibility

An online casino’s welcome bonus is of critical importance. Are there free spins on offer? If so, how many? How much do online slots contribute to the welcome bonus? What are the wagering requirements? How many games apply to the bonus? If there are no free spins, how much of the bonus money can be used on slots?

Dedicated Slots Section

It’s important to look at how an online casino advertises its slot games, and how easy they are to find on the platform. We check to see whether slots have their own specific section on the website, and if they’re categorised even further. Is there a section for new slots? Do jackpot slots or Megaways slots have their own tab? It all matters.

Recent Slot Game Releases

Developers across the industry release hundreds of new slots every month, so a good online slot casino has its finger on the pulse for the hottest new titles.

How Do I Choose a Slot Site?

Here are some key factors to consider when choosing a slot casino.

Licence

Double-check that your chosen casino has the required licenses - betting with an unlicensed casino can put you at serious risk.

Icon 22

Secure domain

Make sure that you’re playing on a secure platform as you’re handing over lots of sensitive information to the online casino.

Best Game Selection

Online Slots FAQs

What is the best online casino for slots in the UK?

We would recommend Videoslots, Mr Vegas and Pokerstars as some of the best casinos for online slot games.

What site can I play slots for real money?

There are several online casinos where you can play slot games for real money. Jackpot Village, LeoVegas, Playzee, Betfred, Quinn Casino and MrQ are just some of the online casinos we would recommend.

Do all casinos offer online slots?

While there may be some obscure online casinos that don’t offer slot games, 99% of online casinos you come across will do so. Slots are the most popular online casino game so it will be detrimental to a casino’s popularity to exclude slots from their game library.

Are online slots games rigged?

No. Online slots use random number generators (RNG) to determine which symbols fall. Although some slots have lower Return to Player (RTP) percentages which suggest a lower number of winning spins, the games themselves aren’t rigged against you.

Is it safe to play online slots for real money?

Yes - as long as the casino you’re playing with has the required licence, it is completely safe to play online slots for real money.

Can I play all online slots on mobile?

The vast majority of online slot games are playable on iOS and Android devices. You can access them either through your mobile browser, or by downloading a casino’s dedicated mobile app and playing through there.

Are the top slot sites licensed in the UK?

Every casino we review and recommend has a valid UKGC gambling licence.

Where to find a welcome bonus for slots?

If a casino doesn’t have a banner on its homepage advertising its welcome bonus, you’ll be able to find the bonus under the promotions tab. Every casino review on CasinoRange has the welcome bonus displayed at the top of the page, and in the ‘Welcome Bonus’ section of the review.

How do I choose the best slot site for me?

There are several factors to consider when choosing the best slot site, such as game selection, bonus compatibility, licensing and the software providers supplying the games.
