How We Select the Best Slot Sites

We have some suggestions of the top platforms where you can enjoy all the best online slots. Casino sites that accept players from the UK, are a particularly good choice. And the reason for this is that all the top slot sites in the UK are regulated by the highly respected UK Gambling Commission and hence are safe and fair online casinos where you can enjoy your favourite games.

Slot games are by far the most popular type of online casino games. And so it’s hardly any wonder that this is the most numerous and vibrant category of games, as well. Naturally, there’s also a large number of platforms offering online slots. But with such a sea of options to choose from, it can be difficult to narrow down the selection. So we’ve decided to do that for you. Picking out the best slot sites and best slot casinos particularly is no easy feat. Here’s how we go about the process.

Slots Variety

 

Slots come in different themes, with numerous different structures and are often built to accommodate different sized pockets. That is why it’s essential that an online casino not only feature the top slot games, but also have plenty of variety for players to choose from.

Slot Site License

 

Licensing is paramount when dealing with any type of online slot site. We look out for the licenses of the casino sites we list, and we also pay attention to the exact authorities who have issued the licenses. This is the #1 one means of ensuring a casino will treat players fairly.

Payments

 

Payment methods are important as well, and just as with the games – there needs to be a decent selection for players to choose from. We also look at the exact type of payment providers supported, noting those that are exceptionally secure, convenient and fast.

Customer Service

 

Customer service plays a vital role in the slot site’s daily operations and we make sure that it is up to par. The casino’s representatives need to be able to provide adequate assistance for players, resolve issues promptly and have a quick response time.

Slot Sites with Bonus Offers and Exciting Extras

Casino offers are a huge deal in the iGaming industry. You will be very hard-pressed to find a site that doesn’t offer any bonuses. And the more time goes by, the more generous these promotions and bonus offers tend to become. Furthermore, slot sites with bonus offers are also becoming more creative in the way they package these offers. Common examples of your most frequently encountered types of bonuses include welcome packages and reload offers. And in both cases, players usually need to make a deposit to claim whatever bonus is stated in the promotion.

But there are also many more types of online casino bonuses to take advantage of out there. For instance, free spins on registration UK are a trendy type of bonus aimed explicitly at slot players. They’re a great way to get some extra value for your money. And in most cases, they also provide a fun, risk-free way to explore new games at the online casino. Also, the top online casinos have sophisticated VIP clubs and loyalty programs to reward returning players. And by becoming a member of these programs, players can benefit from more exclusive promotional offers, including even personalized bonuses and freebies.

Slot Sites with Free Spins

Free spins bonuses are perhaps the only type of casino promotions aimed at a specific kind of game – slots. And since this is by far the most played category of casino offerings, there’s a sea of slot sites with free spins bonuses out there. However, not all such bonuses are made the same. And as it so happens, just like with other types of bonuses, there’s a variety of packages that free spins can be delivered in. For instance, you can receive free spins as an addition to the main bonus in a casino’s welcome offer on your first deposit.

Alternatively, you may not even be required to make a deposit. Popular offers like free spins for adding card, for instance, only ask that you add your bank card to your casino account. And then, you can also benefit from free spins that come in various sized packages. A prevalent number of free spins often seen at online gaming sites include 20 free spins. And you can check out our list of some of the best promotions currently offering that exact amount.

Slot Sites No Deposit Bonus Offers

Among the many different promotions you can find on slot sites, no deposit sign up bonus uk offers have to be among the most attractive. And it’s only reasonable because you get to enjoy some free cash without having to deposit any money of your own. And on the best slot sites, no deposit bonuses can generally take two forms. They can either be offered as bonus money, which you can then use for various casino games. Or, which is perhaps the more common scenario, the no deposit bonus can come in the form of free spins. And in that case, obviously, the bonus would be intended for slot games.

It’s common for free spins bonuses (especially those offered without a deposit) to be granted for a specific title or maybe a selection of several titles. So one thing to always check with such offers is the exact slots they’re provided for. After all, to make those free spins count for something, you want to use them on a game or games that really appeal to you. We’ve rounded up some of the best no deposit bonuses on the market – all in one place. Feel free to browse through our list and see if you may find an offer that catches your eye.

Slot Sites with No Minimum Wagering Required

No wager free spins are another fantastic, albeit less frequently found, type of bonus offer. You can check out our list of current no wagering free spins promotions for an overview of the hottest offers at the moment. But here’s what makes this type of bonus remarkable. All other types of bonuses usually have wagering requirements attached to them. This means that players have to stake the value of the bonus (in most cases, sometimes it can be the value of the bonus combined with that of your deposit) a certain number of times.

And once they have done so, they release the winnings and can be free to cash them out. In the case of slot sites with no minimum wagering bonuses, there’s no such requirement. Hence, any winnings from said bonuses are yours to keep immediately. Such bonuses are usually offered as a form of cashback, or often also as part of casinos’ loyalty programs. But it’s not impossible to find small no-wager freebies aimed at new players, as well. Of course, in this case, you will most likely need to deposit at the site. But as a result, you get to benefit from some genuine, free added value.

Best UK Slot Sites Payment Methods and What to Look For

So say you’ve shortlisted some of the best UK slot sites based on their safety, design, active promotions, etc. Another thing to add to the list of criteria at this point would be the casino payment providers. This is a critical section of all UK slot sites that should never be overlooked. For one, you need to make sure that you can actually fund your casino account somehow. And if the casino doesn’t support any of the payment methods at your disposal, that’s just not going to happen.

Different Types of Online Slots

As pointed out, slot games are the most versatile type of online casino games. Slot games differ by style, theme, structure and a whole list of other factors by which they can be grouped. Here is a list of some of the most popular kinds of online slot titles.

Multi-Payline and Multi reel

 

These are the more common and more modern variations of slot games that come with more than just 3 reels. Usually they offer much more flexibility in terms of betting options. And as a rule the setup in multi reel slots and multi payline slots is much more diverse and often includes various special features and bonus rounds.

Video slots

 

Video slots are basically all slot games that allow you to play via screen as opposed to the old-school mechanical lever and reels. Hence, all slot games that you come across online are video slots. And thanks to them being digitalized, this has allowed developers to so massively diversify the market of slot games.

Progressive jackpot slots

 

Progressive slots are highly attractive to many players because they offer the chance to win huge by hitting the progressive jackpot. Progressive jackpots, in turn, constantly increase as a small amount of each bet made by players goes towards the jackpot. This is also why the stakes in progressive slots may be a little higher.
