How we rank UK Slot Sites

As with any top 10 you need to know what criteria has been used to rank it. We focus in on 6 main areas that we feel are critical for a UK Slots provider to optimise on. You’ll also notice that these factors are discussed extensively in every review we have at Spinathon. Research has already shown these are the most important factors to players. So, we already know what makes you gaming lovers tick and really enjoy your gaming experience. Here’s a little insight into how we rank the best slots sites:

  • Usability – This includes the simplicity of the navigation through-out the sit. Easy and fast registration processes and a user-friendly interface and overall design are favourable. These all play a part in assessing a websites usability.
  • Bonuses/Promotions – Why would you join a site with no welcome bonus when Barbados Bingo run a welcome offer that gives you a chance at up to 500 free spins? You wouldn’t, that’s why all of our top-rated slots sites have some truly breath-taking bonuses and promotional offers.
  • Games/Software – No one wants to play any old boring game. We want classics like Fluffy Favourites, unique games like Finn and the Swirly Spinn and games with amazing graphics like Gonzo’s Quest. Having the ability to mix it up with a diverse selection of online slots games at a site is very important.
  • Banking Methods – Variety is critical for this category, you can never really have too many options. As its all about personal preference when gaming on UK 5 star slots sites. Having all the different types such as mobile payments, debit/credit card, online wallets and pre-paid cards is vital. It ensures players can be comfortable depositing and withdrawing with ease.
  • Security – Spinathon view this as the priority category. So, if a site has poor security we wont feature it, as our readers safety means everything to us. There’s no reason for modern online sites not to use SSL Data Encryption from any industry. It is well ahead of its time and helps keep financial and personal data secure. You’ll find all the sites we feature use this technology, even the casino and bingo site reviews at Spinathon use it.
  • Customer Services – This is all about you, the players. So, if a UK-based brand has poor support that means they don’t care about their players and definitely can’t qualify for our best rated UK gaming site list.

It takes a lot for an operator to make this short list and that’s something we’re proud of. We pride ourselves on bringing our readers the best casino reviews in the UK. Ensuring you make the most of your deposits and have an unrivalled online gaming experience.

Top rated Online Slots Vs Land-Based Casinos

It’s no secret the world of online gambling has been bursting with success from year to year, especially in the UK. Showing consistently high levels of growth in popularity across the board. In comparison to the slow decline of land-base casinos, who are being greatly outcompeted thanks to the diverse benefits of online gaming. There’s plenty of advantages for both sides of the arguments, although the industry shows online Websites as being more popular, it’s all about your own personal preference. After all there’s still plenty of land-based casinos turning good revenues. Here’s a few topics we’d like to touch on why Online is so much better.

Larger Slot UK Selection

Due to space restrictions not even some of the world’s biggest Casinos, even ones in Las Vegas are able to have enough machines available. You might have even visited your local casino to find there simply wasn’t enough machines for each person. So, you’ve been forced to stand there and wait, sometimes for way too long. That’s an area online excels in, there’s simply no limitations when it comes to room, you can get as many games as you want on an online UK website. There’s much more opportunities that present itself thanks to a greater selection too. For example, you can shop around for the best pay out rates. Or, you can play it for free as a demo to get into the swing of things and learn the different features.

There’s also the addition of much more interesting and fun prizes to be earned. For example, the bonus features of individual games are all unique to the game. So, with hundreds of games on the slots sites reviewed by us there’ll be plenty exciting bonus features. Moreover, the best online Progressive Jackpots continue to amaze us. With Microgamings very own Mega Moolah paying out over £16 million from a 25p stake. The amount of money that can be won with these top sites for games is endless.

Anywhere & Anytime

Another problem that is eliminated with online is the fact land-based casinos do not open 24/7. They are also restricted by numerous public holidays and can often close due to bad weather or an unforeseen event. However, in the world of UK online slots sites, these factors are eliminated, they don’t require active staff members 24/7. The site can be left to run all day every day. You’ll never ever be in competition with others for a machine when online. This being as an unlimited number of players can be on one game at the same time.

There’s also the bonus of you not actually having to travel to get access to the best UK games online. Wherever you might be, on the bus home from work, relaxing watching tv or any point in the day you have some free time. You’ll be able to get instant access to an online slots site from anywhere in the uk. If you do find yourself with some free time but don’t know which brand to try out, then you can take a look at some of our best reviews to help you finalise your decision.

No Wagering Limitations

With the recent restrictions put in place by the UK Gambling Commission, seeing £2 restrictions on land-based slots. As well as many of their machines being fixed to one price, this has put many players of. Whether you’re a high or low roller this can be a common frustration. For Top Slot Sites Online there’s much more variation in terms of the betting amount. Whether it be 1p, 5p, 10p or moving into the higher rolls like £5, £10, £20 or above. The £2 restriction doesn’t apply and there’s a much larger acceptance for low rollers, its very rare you’ll find a 1p machine. But, with online since there’s unlimited space they can afford to welcome low rollers as well as high.


For many years all forms of gambling have been stigmatised and associated with negative connotations. For many people that makes it difficult for them to walk into a land-based casino. With the fear of everyone’s eyes being locked onto them casting judgement. However, the addition of online gambling and playing top slot sites online eliminates this issue. You can literally stand right next to someone and be gambling without them knowing on your mobile. This means you can be stress free when relaxing on some of your most loved games.

If you want to try spinning those reels for the first time, then a welcome offer would be a good start. But, getting the right one is the hard part. All these terms and conditions are understandably very confusing to new players. For example, some online casinos will let you keep the cash won from free spins whereas some will place 20x 30x or above wagering requirements. These wagering requirements on some sites can sometimes be so high that it’s very hard to see a return. So, that’s why we’re here to give you a helping hand. Each of our online slots reviews will talk about the online casinos bonuses. Helping you to assess if they’re worthwhile or not.

We’ll also touch on some of their bonuses for regular players, if they do have any. This way our best online reviews will provide you with everything you need.
