The following list is our guide to the 11 best online slots sites for UK players in 2020. Every one of them has its own brilliant features.

Our guide highlights one reason you have to visit each of the superb slots sites in this piece (and that’s before we even mention their slots sign up bonuses).

bet365 Slots

Best online slots sites in the UK in 2020 for Exclusive Slots

Exclusive slots are one of those key features that can lead you back to the same UK online slots sites time and time again. The bet365 slots site has an abundance of titles you won’t find anywhere else housed in its bet365 Originals stable.

There are some truly inspired themes here, with Zombie Pirates From Outer Space, Dr Elemento’s Polar Plot and Mariachi de los Muertos offering a window into the kind of games on offer.

888casino Slots

Best online slots sites in the UK in 2020 for Finding The Best Slot For You

Finding the right slot for you is about more than typing its name into a search box. Yet some UK slots sites don’t even have a search option to help you find what you’re looking for amid the hundreds of games they offer.

What makes 888 Slots so great for finding the slot you want, alongside its search facility, is the checkboxes you can use to search for types of slots rather than just a particular title.

This allows users to make searches for the likes of 888 exclusives, slots with 25+ paylines, or slots by software houses like Netent and many different combinations. It’s an innovation we’d like to see more of as it allows you to find the slot that’s best for you.

Unibet Slots

Best online slots sites in the UK in 2020 for Customer Service

There are all kinds of reasons that even the most experienced slots player may need a little help from their online slots site from time to time. Maybe you’re having trouble triggering a promotion, need help verifying your ID, or setting up deposit and withdrawal methods, for example.

In such circumstances having someone to speak to is really reassuring and Unibet offer support to account holders 24/7. Unlike their few rivals who can match this commitment to customer satisfaction, this relates not just to live chat, but to telephone support from actual human beings. Bravo Unibet.

32Red Slots

Best online slots sites in the UK in 2020 for Slots Demo Play

The reasons to seek out demo slots are plentiful, from playing demo slots for fun to using them to improve your understanding of gameplay in a particular game before putting up your hard-earned cash to play real money slots.

Yet pretty much all UK online slots sites have an oddly inconsistent offering when it comes to demo play options, which are often either hard to find or simply not there for many of their titles.

Step forward 32Red Slots, where the demo play option is clearly labelled for every single slot on the site, making it easy to enjoy slots demo play on any of their titles.

Paddy Power Slots

Best online slots sites in the UK in 2020 for Jackpots

“Winning a daily jackpot on Paddy Power isn’t special,” as the self-styled ‘Special One’ Jose Mourinho reminds us in his advert for Paddy Power games, because you have the chance to do so when you play Jackpot slots games each day on the site.

However, when it comes to online slots sites in the UK Paddy Power is special, with Jackpot slots feeding into six progressive Jackpots on the site, including four Must Drop Jackpots, each growing constantly.

Alongside their regular daily Jackpots, which include prizes that must drop before a certain time or win amount, there’s also slots which form part of the Jackpot King network, where the biggest Jackpot at the time of writing was heading towards the £3m mark.

William Hill Slots

Asian slots are one of the most popular slots genres around and William Hill has to be the best online slots site in the UK for this speciality, thanks to it’s dedicated Macau section.
