Free spins are a great way to stretch your slot budget even further, so you can keep the fun coming! They’re some of my favourites on the market, but they can be a little tricky to find, and there’s nothing more frustrating than when it turns out they’re actually not free after all.
To make my life that little bit easier, I tend to use comparison sites like Online-Slot.co.uk to do all the research for me—but even then, you can’t just pick a random option and begin spinning! Before I select any comparison site, I make sure to follow the below evaluation criteria to check it’s up to scratch.
What Makes a Standout Comparison Site?
The range of free spins bonuses was, of course, in the forefront of my mind for this investigation—but there were also some other equally important things to consider as well!
- Team Credibility: one of the most important things to check at any comparison site is whether their team actually cuts the mustard; I always want to see that they have a good deal of experience in the industry so I can feel sure they know what they’re talking about.
- Range of Free Spins Bonuses: there should be a wide range of free spins bonuses to choose from, with budget options as well—like low and no deposit bonuses.
- Quality of Reviews: I always want to see that their reviews are detailed—covering everything I want to know about a slot—and are truly a valuable tool in guiding me towards the right slot.
- Selection Process: having a huge range of slots on offer means next to nothing if they’re not very carefully chosen; that’s why I look at the site’s selection process to determine whether it’s thorough enough.
So, now we know what I looked at when evaluating Online-Slot.co.uk, let’s see whether it measured up. I gave each factor a mark out of five thumbs up, and you can find my overall verdict at the end of this article.

Team Credibility 5/5
I definitely think it’s fair to say that Online-Slot.co.uk boasts one of the most impressive teams I’ve seen at a comparison site, with a wealth of experience behind them. I counted, and they have over 80 years’ worth of industry experience under their collective belt! I also found it really insightful (and cool!) that they provide their selection process for determining which authors to work with; they make sure potential authors undergo rigorous tests on their slot knowledge and review skills, which is why their team really are the best out there.
Which Team Members Really Shine?
Although I was utterly spoiled for choice in this category, I’d say that Martin Backhouse is probably the most valuable team member for those looking for free spins. Not only does he have 18 years’ worth of industry experience, but he has specific knowledge of how bonuses work, thanks to the time he spent at some of the biggest casino providers.
Another standout was Emilija Cvijanović, as she’s not only spent 10 years in the industry, but also has a wealth of first-hand experience. I’ve always found that reviewers who are players themselves give the best insights when writing about slots, which is why I was excited to read about her passion as a player.
Range of Free Spins Bonuses 4.8/5
It quite literally took me a matter of seconds to locate the free spins bonuses on offer at Online-Slot.co.uk through their separate section under ‘Bonuses’. I was pleasantly surprised with the variety of options I found through their page, with the number of free spins ranging from 11 to a super generous 250!
On top of that, it was great to find a couple of no wagering options, which are a personal favourite for avoiding the disappointing sting of high wagering requirements! For those who want more from their free spins, there’s also a good deal of combo offers where they’re offered alongside match deposits.
Why did I Knock a Few Points Off?
Although I was pretty impressed with the range of free spins bonuses on offer at Online-Slot.co.uk, there can always be more to choose from. I noticed they did refer to the slots as their ‘best options’, which made me wonder if there were any additional options elsewhere on their site. After a little careful investigation, I was able to determine that they do have other slots with free spins on their site. I definitely think it would be helpful if they added the other options to this specific page, even if they keep them separate from their top options.
Quality of Reviews 5/5
All the hours of effort and research that go into Online-Slot.co.uk’s reviews definitely do shine through; they undoubtedly provide some of the most detailed reviews I’ve encountered. When I wanted to know more about a slot offering free spins, I clicked on the long-from review handily linked for each of the options on their toplist.
The reviews I read covered absolutely everything I could possibly ask about a slot, including bonuses, security, payment methods, slot variety, and customer support. What really sets their reviews apart from the crowd is that they’re actually easy to read, despite being incredibly detailed. In the past, I’ve really had to slog my way through dense reviews, but Online-Slot.co.uk avoids that by breaking them into quickly digestible tables and graphics.
Some of My Favourite Review Features
There were a couple of things that made me think that Online-Slot.co.uk’s reviews were truly industry leading, such as their helpful payment table. They break down each of the payment methods available at a casino—from bank transfers and cards to e-wallets—and highlight their minimum deposit and cashout, as well as their withdrawal time. Condensing this information into a very clear table format made it super easy to digest and saved me a good deal of time.
Selection Process 4.9/5
I was able to appreciate just how thorough the selection process at Online-Slot.co.uk actually is; they consider everything I would expect and even more. Of course, they’ve got the basics—like customer service, bonuses, game variety, and payment methods—down, but then they also go above and beyond this by taking slot specific details into account. They consider things like RTP, volatility, paylines, and themes, and their extremely comprehensive process means there’s no room for slots that don’t meet their exacting standards to slip through the cracks. I’d say that players are pretty much guaranteed a good experience whichever slot they opt for!
It couldn’t have been clearer that Online-Slot.co.uk genuinely cares about players, as they only work with slots that have been licensed by the most reputable body in the industry—the UK Gambling Commission. I found it really refreshing to see that safety was one of their top priorities, rather than being left behind by the glitzier topics of something like bonuses or game variety.
Why Not the Full Five Out of Five?
One thing I didn’t love was that the slots in their toplists are not in order of their star rating; it was a little confusing to see a slot with 3.8 out of 5 in third, while one with 5 out of 5 was in sixth. For me, I didn’t understand why you’d go to the effort of having such an incredibly thorough selection process to almost disregard the score! I’m sure there’s a reason why the slots are ordered in this way, though, which is why I’ve only shaved a very tiny 0.1 off their score.
Is Online-Slot.co.uk the Best Place to Find Free Spins?
From my experience using the site, I wouldn’t hesitate at all to recommend Online-Slot.co.uk as the place to go to find free spins! They made the whole experience really simple and painless, with their free spins bonuses easy to locate and their expert reviews offering valuable guidance towards the right option.
I pretty much felt like I couldn’t go wrong at Online-Slot.co.uk, as their highly experienced team and really thorough selection process meant they only offered the very best slots out there. I’m going to award the site a massively impressive 4.9 out of 5 overall, and I would definitely recommend you give it a go the next time you have a hankering for free spins!
