With such a vast array of slot sites available, deciding which to play can be a tricky prospect. Each of them is slightly but significantly different in terms of payout speed, game selection, welcome bonuses, mobile-friendliness, and more.

This means that there is no “best” slot site for absolutely everyone. Nor is it worth your time to sign up with one after another until you find the site that works for you: let us do this instead. From established online casinos to relative newcomers, we’ve hand-picked some of the best slot sites UK gamers can use to help you with your choice.

Best Online Slot Sites in the UK

With at least two of the top slot sites 2022 has to offer attracting over half a million British visitors each month, it's fair to say that most people have a favourite. You may be surprised at just how many diverse options you have once you cast your net beyond the major names, though. Here are some of our best recommendations:

 

Race Casino – visit here

Race Casino is also on the hunt for new customers, offering both a first deposit bonus of up to £100 and 10% cashback. More impressively, they host over 1,500 different slot games. It's fair to say that you'll find one or two you’ll like.

Some table games are available as well, though this doesn't seem to be Race's primary focus. Instead, they host monthly slot tournaments in which you can compete with other gamers. Regular jackpots also encourage you to try your luck. Payouts are generally done within a day for e-wallets (PayPal is not supported at present), though they take significantly longer if you use a bank account.

Pros:

Decent range of slot games

Good customer support at any time

 

Cons:

Website not the best on mobile

 

Welcome bonus: 100% up to a maximum of £100 (+ 10% cashback)

#AD New customers only. Min deposit £20. Wagering 40x. Max bet £5 with bonus funds. 100% up to £100. Eligibility is restricted for abuse. No max cashout on deposit offers. Welcome bonus excluded for players depositing with Skrill or Neteller. Cashback applies to deposits where no bonus is included. Cashback is cash with no restrictions. Full T&C’s apply.

Spin Rio – visit here

One reason for choosing Spin Rio is their higher-than-average sign-up bonus of up to £200. Users can then take advantage of a well-balanced selection of around 1,500 games, including several slots.

One feature worth pointing out is that Spin Rio's betting limits are very flexible. With slots, you may choose to wager as little as a few cents or as much as £100.

Pros:

Uncomplicated, user-friendly website

Several progressive jackpots

 

Cons:

Special promotions are relatively rare

Welcome bonus: 100% up to a maximum of £200 + 100 free spins

Applies only to new depositing players. 18+. Minimum deposit: £10. 35x Wagering requirement applies to match up bonus. Spins credited in specific games. Spins expire after 24 hours. Wagering requirement applies to spins. Terms and Conditions apply.

Casino Gods – visit here

With over 1,700 slots and numerous table games available online, Casino Gods has a charming Greek mythological theme weaved into their website and promotions. This doesn’t, of course, affect your actual gaming experience but is a nice touch.

The first deposit bonus is in line with most top online slot sites' UK offerings. You'll find, however, that a number of ongoing promotions make Casino Gods a very prudent option, especially for frequent gamers.

Pros:

Plenty of free spins for regular users

Clear website design

 

Cons:

PayPal deposits aren’t eligible for bonus

Welcome bonus: 100% up to a maximum of £100 + 300 free spins

18+ Full T&Cs Apply. New UK players Only. £10 min. deposit. £5 max. bet using Bonus. 40 x wagering applies. Bonus valid for 14 days. 30 Spins on pre-selected games will be credited instantly + then 30 per day for 9 days. Free Spins valid for 72 hours from credit. Max. Free Spins winnings £100. Ewallets excluded. www.begambleaware.org.

Casumo – visit here

Casumo’s offering consists of a selection of more than 2,000 games, many from the world’s leading software providers, and incudes many live table games. These, rather than slots, are Casumo's main business: much of their site is geared to people who prefer to interact virtually with a real human dealer.

Their selection of slots is respectable, however. In addition, Casumo holds tournaments every week and provides an attractive number of jackpots. Every time you take a spin, you also receive loyalty points. One great feature of this online casino is that it comes with a dedicated, user-friendly mobile app - you don't need to use the browser on your phone to play.

Pros:

App for iOS and Android

Constant promotions

 

Cons:

Welcome bonus not as generous as others

Welcome bonus: 100% up to a maximum of £25 + 20 free spins

*18+. New UK customers only. Opt-in required. 20 Bonus Spins on "Book of Dead" and 100% Deposit Bonus up to £25 on first deposit. Min deposit £10. 30x wagering requirement for Bonus Spins and 30x wagering requirement for Deposit Bonus (game weighting applies). Max £5/spin or £0.50/line or £10/round (live casino). 30 days expiry. Full T&C's Apply. Please gamble responsibly • www.begambleaware.org

All British Casino – visit here

For some time now, All British has been willing to match every pound of your first deposit (up to a maximum of £100) plus give you 10% cashback on losses. This is certainly a valid incentive, as is a pretty slick website and a stable of over 500 games.

These go well beyond slots, with classics like live roulette, baccarat, and multiple flavours of poker rounding out their offering. If cards aren't your thing, don't let this put you off: All British remains one of the best slot sites UK players have come to love - including on mobile devices.

Pros:

Vast selection of games with various stakes options

Superb graphics

 

Cons:

Customer support only runs from 7am to midnight

 

Welcome bonus: 100% up to a maximum of £100

#AD New customers only, min deposit £20, wagering 35x, max bet £5 with bonus funds. Max bonus is 100% up to £100. No max cash out on deposit offers. Welcome bonus excluded for players depositing with Skrill or Neteller. Cashback is cash with no restriction. Full T&C’s apply.

Kassu – visit here

This UK online slots site sports a quirky site design that will appeal to a wide ranging audience. Kassu hosts over 700 slot games, more than a hundred live games, and a significant number of jackpots. As is common with online slots sites, new UK customers may receive a sign-up bonus of up to £100 plus 300 bonus spins. This offer is only valid if you choose a bank account as a payment method, though a wide range of payment options are accepted.

This is made easier by a mobile version of the site, which works very well. If you're a night shift worker, unfortunately, you won't be able to count on live customer support outside 9am to 1am.

Pros:

Good variety of both slots and table games

Several payment options

 

Cons:

Not eligible for bonus if depositing by ewallet

Welcome bonus: 100% up to a maximum of £100 + 300 free spins

18+ Full T&Cs Apply. New UK players Only. £10 min. deposit. £5 max. bet using Bonus. 40 x wagering applies. Bonus valid for 14 days. 30 Spins on pre-selected games will be credited instantly + then 30 per day for 9 days. Free Spins valid for 72 hours from credit. Max. Free Spins winnings £100. Ewallets excluded. www.begambleaware.org.

Plaza Royal – visit here

This online slots site is relatively young but already has a good reputation. It hosts over a hundred live games and around a thousand slots. Its mobile version performs quite well, while the website is easy to navigate.

One concern, unfortunately, is that customer support is only available from 7am to 11pm. Not everybody will need their services, but it is a little odd that their help centre only functions while physical casinos are open.

Pros:

Wide range of payment methods accepted

Attractive (up to £200) welcome bonus

 

Cons:

Withdrawals are occasionally slow

Welcome bonus: A maximum of £200 + 100 free spins

Applies only to new depositing players. 18+. Minimum deposit: £10. 35x Wagering requirement applies to match up bonus. Spins credited in specific games. Spins expire after 24 hours. Wagering requirement applies to spins. Terms and Conditions apply.

Fun Casino – visit here

Fun Casino doesn't have quite the variety of games some online slot sites can boast. It should still satisfy the majority of players, though, with over 1,000 games in total to choose from. You're free to try your hand at table games when slots become dull.

Alternatively, you can take a chance on winning jackpots that are often in six figures. Payouts are typically processed in under 24 hours on any of a number of platforms (debit cards take a few days, which isn’t the casino’s fault). Although their web and mobile experiences aren’t as polished as some competing top slot sites, commuters will appreciate that most games can be run on their phones.

Pros:

Responsive, 24/7 support

Variety of jackpots available

 

Cons:

Acceptable but unspectacular range of slots

Welcome bonus: 100% up to a maximum of £123 (+10% cashback)

#AD New players only, Maximum bonus is £123, Max bet with bonus is £5, No max cash out, Wagering is 50x – Skrill & Neteller excluded, Eligibility is restricted for suspected abuse, Cashback is cash, so no wagering, Cashback applies to deposit where no bonus is included. Full T&C’s apply.

Casino Lab – visit here

With something of a playful vibe compared to many other top online slot sites, Casino Lab offers something over 1,500 slot games. It also offers an extensive video casino with live dealers for some variety.

Upon joining, you will be given £100 as long as you deposit an equivalent amount, as well as a relatively generous 300 free spins. Note that this only applies if you register with a debit card; e-wallets work on Casino Lab but not for this welcome bonus. Overall, though, this doesn't really matter: promotions for existing customers are run all the time. In keeping with the site's theme, these are called things like "experiments" and "potions”.

Pros:

Numerous jackpots and special offers

Several payment methods

 

Cons:

Not eligible for bonus if depositing by PayPal

Welcome bonus: 100% up to a maximum of £100 + 300 free spins

18+ Full T&Cs Apply. New UK players Only. £10 min. deposit. £5 max. bet using Bonus. 40 x wagering applies. Bonus valid for 14 days. 30 Spins on pre-selected games will be credited instantly + then 30 per day for 9 days. Free Spins valid for 72 hours from credit. Max. Free Spins winnings £100. Ewallets excluded. www.begambleaware.org.

Mr Play – visit here

With a maximum welcome bonus of £200, subject to the usual terms and conditions, Mr Play follows a policy of choosing quality over quantity when it comes to selecting games. Slots are well represented (1,000+ games) with numerous other options to pass the time. Unusually for an online slots casino, it also allows you to bet on a huge number of sporting events worldwide.

Mr Play has a highly structured loyalty program that's worth checking out. Mobile users, instead of accessing the website using a browser, are encouraged to download the Mr Play app for iOS or Android.

Pros:

Mobile version is well organised

Sports betting is supported

 

Cons:

No regular tournaments

Welcome bonus: Maximum of £200 + 100 free spins

Applies only to new depositing players. 18+. Minimum deposit for 1st deposit bonus: £10. Welcome Package split over 3 deposits. Minimum deposit for 2nd & 3rd deposit bonus: £20. 35x Wagering requirement applies to match up bonus. 100 spins splits to 20 spins a day for 5 days. Spins credited in specific games. Spins expire after 24 hours. 50x Wagering requirement applies to spins. Terms and Conditions apply.

How We Ranked The Best Slot Sites (UK)

It's well-known that running a casino amounts to a licence to print money. Unfortunately, a number of dodgy operators have emerged online and decided to take greater liberties. In the first place, therefore, all the online slot sites UK citizens may want to visit have to carry a Gambling Commission license and follow all UKGC regulations. This applies equally to top online slot sites hosted or managed in other countries.

We can't rely on the government to sort out everything, though. In particular, online slot sites UK users can trust have to implement industry-standard digital security measures. Considering the amount of personal data held on their computers, this (as well as a reputation for protecting their customers' interests) is non-negotiable. A further concern is the fairness of the actual games. All of the top slot sites 2022 still finds up and running use independently produced and verified software for this purpose.

All casinos listed here meet these basic requirements, and we do not recommend using one which doesn't.

Other things we looked at include clear terms and conditions, helpful customer service, and how easy it is for you to choose between various payment options, including Trustly. Last, but certainly not least, we also chose the best online slot sites based on the total experience. Modern bettors demand an easy-to-use interface, a wide variety of games, interesting graphics, and competitive introductory bonuses. You need not settle for less.

 

How to Sign Up to an Online Slot Site

The best online slot sites have a very streamlined process for joining - after all, irritating their customers isn't exactly in their best interest. In general, it goes like this with, only minor variations between the different top slot sites of 2022:

  1. Most people prefer to choose a single gaming website and stick with it. Hopefully, our list of top online slot sites has given you an idea of which you'll prefer.
  2. Simply click on the "Create Account" or "Register" button on any of the best slot sites' front page.

3. Fill in some basic information - name, email, etc. This takes under five minutes, though you will have to supply identification and proof of your address.

4. Once your account has been created, you'll need to deposit some money. Depending on which payment methods your chosen slot site accepts, you may do this by bank transfer, an electronic payment service like PayPal, or even using cryptocurrency.

5. At this point, you're all set to start playing. Good luck!

 

FAQs

Are online slot sites safe?

Slot sites UK law governs are generally comparable with brick-and-mortar casinos in terms of security. That having been said, it's still wise to use a bit of common sense. You may, for instance, want to compare the Ts&Cs of a couple of online slot sites regarding issues like minimum withdrawal limits.

 

Is online gambling legal in the UK?

Subject to some pretty basic stipulations, online slot sites are absolutely permitted in Britain. Note, however, that players must be 18 years of age, and HMRC takes a very dim view of people who use gaming as a way to launder money. On a related note, winnings are not taxable - if this were the case, losses would logically be deductible, and that would be chaos.

 

How do I check that an online slot site is licensed?

As a quick first check, see if you can find the UKGC logo on their website - all the best online slot sites UK citizens can trust display this. If you have any doubts, it may be a good idea to search for the website or company name on the Gambling Commission website itself.
