Online slots in the UK

You’re likely aware that online casinos are huge in the United Kingdom. The online gambling industry alone is worth around £5 billion and has been growing steadily since its inception. Online casino betting has become more than business, it has its own culture, language and style.

Given that fact, it’s no surprise that there are hundreds of different slot games available for players at any given time. While it can be difficult to decide which ones to play based on reviews alone, here are some of our favourites.

The top 10 slots in the UK

Not every online slot game is created equal. Some are simply better than others, and your own personal preferences will likely play a major role when choosing which games to play. One of our favourite online slots, for example, is Gonzo’s Quest, with its excellent graphics and gameplay — and who can forget that adorable explorer? 

Our top 10 slots in the UK list, however, only contains those that fall into a category we like to call fun. These are UK online slots that you can count on more often than not to give you a good time, no matter what the results.

  • Starburst
  • Gonzo’s Quest
  • Big Bass Bonanza
  • Book of Dead
  • 9 Pots of Gold
  • Wolf Gold
  • 9 Masks of Fire
  • 777 Strike
  • Twin Spin
  • Thunderstruck

The classic slot - Starburst

Starburst is an online slots game that has been around for some time. It’s a classic – and not just because it first appeared all those years ago. A truly timeless game, it continues to be hugely popular among online casino UK players. 

Part of its enduring popularity has to do with its simple design: three rows of five icons (nine altogether) with no more than two adjacent symbols featuring either wild or scatter symbols. This can make Starburst quite engaging for newbie players who enjoy cherry-picking their way through paying lines. It’s also a great choice for experienced fans of classic slots games who might want something fresh yet familiar to get started on today’s online casinos UK scene!

The influential and fun slot - Gonzo's Quest

Any Top Ten Online Slots in The UK list will come with a wide range of games, from fun slots to cutting edge graphics. There is something for everyone on our list. But there are a few things that connect these slots,, and one of those is that they are among the most popular online slots in the UK. Gonzo’s Quest is certainly that!

Gonzo’s Quest is all about the personality, not just of the intrepid explorer himself, but the slot design as a whole. It’s the combination of fun gameplay and character driven interface that makes it one of the most influential slots of all time, including inspiring many sequels and copy cats.

The multiple feature slot - Big Bass Bonanza

Big Bass Bonanza is a bright, fun and colourful 5-reel slot game that’s full of online casino bonus features. It has 20 paylines and multiple options for betting amounts and corresponding jackpots, so there's something for everyone.


This awesome online slots game from Microgaming also has a superb RTP (Return To Player) rate of 96.40%. Big Bass Bonanza also includes wild symbols, scatters, multipliers and free spins - which makes it ideal for both high rollers and high-volume players alike.

The cryptic slot - Book of Dead

We consider Book of Dead as a natural development from the classic Book of Ra slot, although it’s hard to choose between the two in truth. It has free spins, scatters and a bonus round, as well as other great features.

The game is named after an Egyptian book that contained information about how to enter into heaven and collect rewards from Osiris. The symbols used are all related to death; there are many references throughout history regarding what was supposed to happen after death, although I’m not sure a high-class video slot was one.

The colourful slot - 9 Pots of Gold

When it comes to the most popular slots in the UK, paylines are one of those things that should never be overlooked. Typically, slot games will have between 1 and 5 lines, while progressive slots will offer much more. If you want to give yourself as many winning opportunities as possible, 5 lines is generally considered a top number for any payline based game. Pots of Gold offers 50 potential winning combinations on each spin thanks to its 5-reel and 25-payline format.


Add that to the colourful and fun aspects of 9 Pots of Gold, and it’s no wonder how it remains a favourite online slot in the UK.

The best graphics slot - Wolf Gold

The online casino bonus round is one of our favourite features in all of gaming. It has a total of five reels that are placed on three different rows, which makes it simple to play and easy to win big amounts from. This 5 reel slot features a jackpot payout that can go up to 1000x your total bet, so it’s no wonder why so many enjoy playing it. 

Immersion is an underrated aspect that is a part of all the very best online slots, and the graphics of this one will ensure that you will be drawn in from the beginning. 

The immersive slot - 9 Masks of Fire

Talking of immersion, the top online slots in the UK seem to get more and more exciting every year and 9 Masks of Fire is a perfect example of that. This not only applies to how games are played but also how they look and sound. UK online slots were once simply two-dimensional card layouts with crisp, clean backgrounds, but they're moving away from that rapidly. 


9 Masks of Fire has hidden elements of gameplay that can be explored before unlocking bonuses like wildcards or multipliers. These 'Easter eggs' add another level of interactivity between players and machines that makes UK online slots ever more engrossing.

The eclectic slot - 777 Strike

This is a simple online slot game that has 1 pay line. It’s designed by Microgaming and has 5-reels, which means you can place up to 20 bet lines at once. The coin value ranges from £0.01 to £1 with a maximum bet of £125 for a single spin of all 20 lines available. 


To win, you need three 7s on one active pay line in order to score big. The progressive jackpot can be won when 3 scrolls appear anywhere on screen. It’s the perfect example of classic online slot game play and innovative online casino bonus features that keep players enthralled.

The interactive slot - Twin Spin

Twin Spin is a fantastic game from Playtech and I have to say it’s one of our favourite online slots. It’s one of only a few bonus slots that lets you choose your own bonus multiplier, providing a level of interaction that allows for a unique experience among online slot games


There are multiple free spins on offer too, but not just any free spins; these come with multipliers! This can lead to some big wins if you hit 3 or more jackpots during this feature. If you enjoy slot games with stacked wilds, then Twin Spin will blow you away!

The innovative slot - Thunderstruck

It would be almost impossible to draw up a list of the top 10 online slots in the UK without mentioning Thunderstruck. If you want cutting edge graphics and a new experience, you should try Thunderstruck II, which is by all measures an improvement on the original, but there’s just something about this old classic that keeps us coming back for more.


It has been played by over 36 million people since its introduction in 2003 and it’s easy to see why. The game features 5 reels and 243 ways to win. It has a top jackpot of 250,000 coins and some of its symbols include Thor’s hammer, Mjolnir, and Odin’s sword. With high-paying symbols like these you know that you are going to have an excellent time playing the Thunderstruck online slot.
