Best Online Slot Sites – How do we Rate the Best Sites?

Before we unravel the fundamentals, it is important for us to briefly outline how we actually rate the best online casino slot sites UK. In a nutshell, our team of in-house experts will personally open accounts with all of the platforms that we recommend on our site.

This then includes the entire player cycle of depositing funds, uploading ID, testing the slots department out, and of course – withdrawing our balance back out.

In doing so, this allows us to provide you with a complete 360-degree overview of how the slot site compares. Crucially, this then allows you to make an informed decision as to whether or not the slot site is right for your needs.

We should also note that we never allow an online casino to influence our reviews. On the contrary, our published results are based on the honest, independent, and impartial viewpoints of our in-house experts.

What Types of Slot Machines do Casinos Offer?

Never played at an online casino before, and wondering what slot machines you will have access to? Well, the best UK online slot sites of 2020 often host thousands of the best slots UK. This includes everything from classic slots, video slots, live casino slots, bonus slots, and themed slots.

This ensures that all player-preferences are catered to. For example, if you’re the type of player that craves non-stop action from in-game specials, bonuses, and features – you’re covered. At the other end of the spectrum, if you prefer classic slots that mirror that of the pub fruit machine – the best UK slot sites also have you covered!

Top UK Slot Sites for Bonuses

As the online casino space has become more and more competitive, the top slot websites have really upped the ante in the bonus department. For example, it was only a couple of years ago that a 100% matched deposit bonus was seen as ‘generous’.

However, this is no longer the case – with the best UK slots sites now offering matched bonuses in excess of 300%! This means that by depositing just £100, you would start with a balance of £400.

In other cases, the best online slots sites UK also offer free spins. This is often complimentary on top of a more traditional matched bonus. If you’re really lucky, you might be able to claim a no deposit bonus. This is where the slot site either gives you free casino credits or free spins – without asking you to make a real money deposit!

Best Slots Sites UK for No Wagering Bonuses

As generous as welcome bonuses are for new players, you do need to have a firm grasp of the underlying terms of the promotion. At the forefront of this is the wagering requirements. This is the number of times that you need to ‘wager’ the bonus funds before you can make a withdrawal.

For example, let’s say that you claimed a 300% matched deposit bonus, with your £200 deposit generating a starting balance of £800. If the wagering requirement on the promotion is set at 10x, this means you need to gamble at least £8,000 at the casino platform before you can withdraw the bonus cash out.

This is why we at only recommend the top UK slots sites for no wagering bonuses – as this gives you the best chance possible of turning our bonus funds into real-world cash!

Which Online Casinos Offer the Highest Slot Payouts?

When it comes to payouts, this isn’t something controlled by the top slot sites UK per-say. What we mean by this is that casinos do not create the slot games that they host. On the contrary, games are designed and licensed by regulated software providers. With that said, certain developers are known for offering more attractive payouts.

One such example of this is NetEnt. The top-rated slot developers offer some of the highest RTPs (Return-to-Player) percentages in the industry. This means that by playing at a slot site that hosts heaps of NetEnt games, you’ll stand the best long-term chance of winning.

Best Slots for Progressive Jackpot Slots

Looking to chase that life-changing win through a progressive slot game? If so, good slot sites often host a number of progressive online slot games that pay jackpots of well over a million pounds.

To date, the largest slot machine win of all time amounts to the 17 million euros won on Mega Moolah in 2013. The icing on the cake is that the lucky punter was playing at stakes of just 25c per spin!

If you’re wondering how the top ten slot sites are able to cover such a huge amount of money, they don’t. This is because the best progressive slot games are managed by software providers. In the example of Mega Moolah – the slot machine will be hosted at hundreds of different casinos.

This means that the progressive jackpot increases on a second-by-second basis, so it only takes a few days before the title approaches that million pounds mark.

If you do decide to play a progressive jackpot game, just make sure that you play at minimum stakes. This is because you have just as much chance of winning the jackpot playing at 25p per spin, as you do playing at maximum stakes!

Best Slots for Mobile Gaming

If you’re the type of player that likes to play slots on the move, the best slot casino sites will usually offer a native mobile app. This is often available on both Android and iOS, and you can download the app at the respective app store.

We at PayByPhoneBillCasino find that the best slots website are pumping vast resources into the mobile gaming department, as this particular segment of the UK gambling space is the fastest-growing. As a result, the end-to-end gaming experience on mobile slot apps is just as good as its desktop counterpart.

Crucially, the top 10 slots sites allow you to access all of the same account features when you use the mobile app. This includes the ability to deposit and withdraw funds, speak with customer support, and of course – play slot games!

Some of the best online UK slots will offer multiple deposit bonuses. For example, while you might get 200% on your first deposit, the following two might come with a 50% boost.

Note: Be sure to check what the min deposit and max bet amounts are when claiming a bonus.

Jackpot Games

If you’re looking to chase a life-changing win, make sure you choose a slot site that offers progressive slots. More specifically, make sure the slots are part of a much wider progressive network. This will ensure that you are playing slot games with the biggest payouts in the space.
