How to Use Top 10 Best Slots Sites

While slot machines were naturally around for a long time before the popularisation of online slots – about a century before, in fact – there’s no doubt that these days, whenever slot games are mentioned, many of us immediately think of casino slots online.

Today, there’s no shortage of sites offering attractive online slots in the UK, ranging from long-established household-name bookmakers to more obscure, themed gaming portals. But if you’re on the lookout for the very best slots sites, you’ll need to spend time carefully researching and comparing before deciding where to play.

Thankfully, here at Top 10 Best Slots Sites, we’ve made it quick and easy for you to compare Britain’s top slot sites, via your smartphone or tablet device. The latter is an important detail: today, all of the best slots and the sites on which they are hosted are optimised specifically for convenient mobile play. That means they’re designed for the smaller screens of such popular devices, thereby helping to provide the most graphically impressive, slick and intuitive slot machine experience.

But there’s more to selecting the finest online slots websites than this, of course. That’s because you’ll also have to consider factors like the below when assessing and comparing slots sites, as we also look into in detail here at Top 10 Best Slots Sites:

Types & Range of Slots Games

Do the slots websites that you are looking at feature both three-reel and five-reel slots? What about the distinction between popular generic slots like Starburst and Rainbow Riches, and branded slots based on popular media franchises, such as Deal or No Deal or Gordon Ramsay: Hell’s Kitchen? Do you have a preference when it comes to what you consider to be the best online slots? 

Many of the leading providers of slots online also offer at least some exclusive games – by which we mean, games you won’t find anywhere else – and intriguing variations on the traditional slots formula, such as Megaways and Slingo games.

Some casinos and slots websites make available hundreds of slot games, while others might have more than a thousand of the finest online slot games for you to sift through. You might be likelier to be satisfied by a site that offers a larger number of top slots, but this isn’t guaranteed – after all, some sites firmly prioritise quantity over quality, or vice versa.

 So, it’s still important to consult the reviews of the best slot sites you’ll find on portals like Top 10 Best Slots Sites, to give yourself the best possible overview of what a given site does well or badly. 

Online Slots Promotions & Bonuses

Any good portal for casino slots, whether on a desktop computer or mobile device, will have a wealth of promos and bonuses to reward players both old and new. 

Discovering what a given slots site offers in this department is as simple as navigating to their ‘promotions’ page – but of course, doing so for every single online slot machine provider would be laborious and time-consuming. 

So why not instead check out our reviews and comparison charts here at Top 10 Best Slots Sites, so that you can discover the new-member bonuses, free spins, VIP schemes, and other promotions and bonuses that each and every well-rated slots website offers? 

Online Slots Website Interface & Usability

While there’s often a lot of overlap between online slot websites in terms of the exact slot games they make available to players, the main website’s design is also important. After all, it’s the first thing you will see when you log onto that site, whenever you’re next in the mood to find the best slots to play. 

This factor becomes even more crucial when you’re looking to play on the small screen of a tablet computer or smartphone. To provide a better experience to such players – including to allow them to find the best slots quickly and easily – the top slot sites use design features such as ‘hamburger’ menus, and might even give the user the option to download a dedicated mobile app for the site.

Privacy & Security 

Unfortunately, not all slots sites implement the fastidious and up-to-date security practices that they should do. So, this is something else that our expert reviewers take a close look at when we review the best slot sites in the UK today.

Does the slots site you’re considering clearly explain what it does to keep your personal data safe? Is the most appropriately sophisticated encryption technology used, and does the site pledge not to sell or otherwise pass on your customer details to other parties? 

You could work all of this out by consulting the ‘privacy policy’ and ‘security’ pages on the top slot sites you’re thinking of registering with... or you could just consult our informative reviews here at Top 10 Best Slots Sites. 

Payment Methods

Another thing that tends to define the best slots sites, is a broad range of accepted payment options. These are the methods you will use to put down a deposit so that you can start playing the given site’s online slot games. 

You might prefer to simply use the same Visa or MasterCard debit card for your slot site deposits that you use for your online shopping, or you may be given the option to use PayPal, Apple Pay, Paysafecard or Trustly – to name just some of the common options.  

With so many payment cards and e-wallets out there these days, it’s well worth knowing which payment methods each leading slots site accepts, as well as the conditions attached to their use – for example, any fees and minimum and maximum deposit and withdrawal requirements. 

Sign-up 

It might not seem a big deal what the account registration process is for your chosen online slots portal. After all, aren’t they all the same – basically just requiring you to provide a few details like your name, postal address, email address, and the username and password you intend to use? 

That might be more or less the case, but there’s an additional dimension as far as mobile play is concerned – ensuring signing up for the slots site is fast and convenient on a smartphone or tablet. 

If there are too many pages you are required to go through just to sign up to a particular provider of online slots in the UK, you might find yourself frustrated and eventually just give up. So, our reviews of the leading online slot websites also scrutinise this aspect of each and every site. 

Ease of Access 

Accessibility is another vital factor to consider when comparing the leading providers of casino slots online. You might presume accessing a given slots website is as straightforward a process as hammering the URL into your smartphone’s web browser – and sometimes, it is. But even some of the best slot sites out there sometimes fail when it comes to certain aspects of accessibility.

Not all slots websites have downloadable apps for both Android and iOS devices. Worse, some sites might not even be optimised for mobile play for those visiting them directly through a web browser. This could make simply trying to access and play games on a given site a rather frustrating experience that will leave you wishing you hadn’t bothered. 

It can be a tricky and overwhelming process to decide which sites offer the best UK online slots – never mind which ones also provide a suitably high-quality interface, promotions, bonuses, customer service, and so on. Plus, not every player has the same needs – so you’ll want to be sure that whatever site you pick caters to your specific requirements. 

So, don’t hesitate to check the comparison chart above to see and compare the latest top slots sites. That way, whether you’re on a desktop or mobile device, you will be able to quickly find the right site for you, and get on with the actual gaming!
