UK’s Top Comparison Sites for Slot Games 

Online gambling is one of the driving forces of the gaming industry, with a new generation of players discovering online casinos. Much of this has been powered by advancing technology in the mobile gaming market, with mobile gaming accounts making up more than 50% of all accounts. 

Although online casinos offer a range of ways to play, it’s online slots that are by far the most popular games among UK players. But where can you find the best slots without spending hours of time and your hard-earned money exploring the thousands of games available today? 

That’s where slot comparison sites come in. These dedicated sites have the sole purpose of reviewing not just slots-based casinos but also individual games. In this guide, we’re going to go through the best comparison sites for slots in the UK. 

How We Review Online Slots Comparison Sites 

Online slot comparison sites vary widely in quality. Google these sites and you’ll find hundreds of options to choose from. The last thing you want is to come across a site that either hasn’t reviewed a site professionally or includes information from years ago. 

 
We also focused on the sites that use the metrics that matter most to players. Some of the aspects we’ve used to determine what the best online slots comparison sites are include: 

Of course, different things matter to different players, which is why we’ve tried to prioritise different aspects to appeal to a broader player base. With 2,343 licensed gambling operators in the UK, we’ve presented a comprehensive range of options for you to choose from. 

6 Best Online Slots Comparison Sites in the UK 

Online slot comparison sites can examine both casinos as a whole and the individual games. Whether you’re searching for a new slot game, want to keep up with the latest releases, or want a new place to play, these sites should be your first port of call. 

Here’s our list of the leading names in the UK market. 

1. Slotgods – 9/10 

Slotgods is a comparison website dedicated to the best online slot sites. Unlike some other comparison sites, they examine casinos as a whole, with emphasis on different casinos’ features, payment methods, and customer support. They also cut through the noise and rate casinos higher if they’ve got a great user experience. 

What stands out about their reviews is that they don’t produce a single overarching rating for each site. Instead, they use a range of separate categories to allow players to get a better idea of where a casino excels and where it falls short. 

 
Additionally, their reviews include rundowns of the different promotions on offer at a particular time. They’ve also got a team that goes through their reviews and updates the information as and when it changes, making it one of the more reliable comparison sites for online slot players. 

 
Like any site, it’s not perfect. Despite Slotgods having an array of casinos covered, it doesn’t cover all of them. Some of the more niche sites that accept UK players don’t feature on the site, which can be a drawback for experienced players who are already familiar with the big names. 

2. Online-Slot.co.uk – 9/10 

Online slot players often hunt for bonuses to maximise their returns. Casinos tend to place a huge amount of emphasis on their online slot bonuses, which is why bonus hunters often play online slots more than any other game. Online-Slot.co.uk recognises this and so provides a comprehensive database of bonuses within their reviews. 

 
If you’re struggling to keep up with the array of bonuses, this site is one that updates its listings on a near-daily basis, giving you a great resource that you can shove in your bookmarks. Aside from bonuses, it also includes some of the more technical aspects of slots, including return-to-player percentages. 

 
Its extensive coverage of slots extends to the more niche casinos, enabling you to uncover online slot platforms you might not find on other comparison sites. 

 
However, where Online-Slot.co.uk falls down is in its design. The design can feel outdated and outright cluttered, which new players may find confusing. Unfortunately, there’s simply too much content on every page, which is somewhat of an assault on the eyes. 

3. JohnSlots.com – 8/10 

JohnSlots is another dedicated slots comparison site, but where it goes further than its competitors is in covering online casinos themselves. Every player knows that it’s not just about the game variety but how the casino functions as a whole – something that JohnSlots acknowledges through its review approach. 

 
It’s got an extremely user-friendly interface featuring a clean and simple design, enabling you to find exactly what you need without thinking about it. Just like Slotgods, JohnSlots features bonuses heavily in its reviews, especially no deposit and no- and low-wagering offers on slot games. It also has the most extensive free slot demos database, unlike other sites that only show video walkthroughs.  

 
The downside is that JohnSlots tends to be aimed at players who really want to get underneath the skin of the UK’s gaming market. Some of its terms can be complex, making some of the bonuses and gameplay mechanisms reviewed difficult to understand. 

On the other hand, JohnSlots excels in a variety of areas, including: 

It’s also worth mentioning that JohnSlots doesn’t let its reviews get stale. Its team updates reviews and ensures that players have everything they need to make informed decisions on where to play. 

4. Slotsites.uk – 8/10 

Slotsites.uk may seem like any other UK comparison site, but it’s much more than that. Rather than simply posting reviews and allowing players to make their own decisions, the platform takes a next-generation approach to reviewing casinos. 

It’s got a nifty comparison tool that lets players take different casinos and compare them one-on-one based on the reviews that have already been published on the site. For example, if you’re someone who wants a wide game variety above everything else, you can use the tool to compare different casinos based on that metric. 

Other metrics you can compare include: 

But what if you don’t know what you want to prioritise the most? The same tool also offers tailored recommendations to point you in the right direction. The user-friendly filtering options provide a more technical approach to comparing casinos and online slot games. 

On the other hand, new players might struggle with the array of information available. Making the most of this tool hinges on having an understanding of online slots and how casinos work. 

It’s not a platform that should be recommended to new players, but its tools are invaluable if you already have an idea of what you want from online slots. 

5. CasinoAlpha – 7/10 

CasinoAlpha aims to be the alpha of the online comparison niche within the UK gaming industry. Unlike the other entries on this list, CasinoAlpha isn’t a slots-focused comparison site. Instead, you’ll find categories covering just about everything within the online gaming market, so it’s ideal if you also like to explore other types of games. 

 
The platform is aimed at players seeking value from the slots games they play. That’s why their reviews are heavily weighted toward the bonus values . However, beyond their testing team, they also incorporate player feedback into their reviews, ensuring that they can come to an unbiased conclusion. 

 
Another area where CasinoAlpha stands out is that it regularly updates its listings with the latest information. This ensures that you’re not left trying to separate outdated information from what’s current. 

 
In essence, it’s what you’d expect from a leading UK comparison site. On the other hand, the issue is that the site is poorly designed. It’s cluttered with information that can seem overwhelming if this is your first time using an online slots comparison site. 

6. BestCasinoSites.net – 7/10 

BestCasinoSites.net is like CasinoAlpha in that it reviews casinos as a whole rather than focusing exclusively on online slots. This is helpful if you’re a player who doesn’t just play slots when gambling. But it acknowledges that many players are slots-only players, which is why it’s got a dedicated category for slots. 

Within their slots category, they cover: 

Its reviews are well-structured, and easy to get ratings at a glance based on the categories you value most. It also incorporates player feedback into its ratings, ensuring you’ve got an unbiased view from real players. 

The problem is that some of its reviews are lacking in the detail you might be looking for. There’s an inconsistency that stops it from being rated higher. In other words, your mileage may vary. 

Conclusion: Find the Best Online Slots Today 

Finding the best online slots is tough when there are literally thousands of options to choose from. However, online comparison sites simplify the process, enabling you to find your next favourite game in minutes. 

 
Any of the above are ideal tools for discovering where you should play and what you should play for the best possible gaming experience. Which online slot platform are you using to find the best games?
