ONLINE SLOT SITES – HOW DO WE RATE THE BEST SITES?

Before we unravel the best slot sites 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 online slot site compares. Crucially, this then allows you to make an informed decision as to whether or not the online slot site is right for your needs.

We should also note that we never allow an online slots 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 which online slot machines you will have access to? Well, slot sites of 2020 often host thousands of games. 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 a pub fruit machine – we 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 some 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 slots sites 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 online slot site either gives you free casino credits, bonus funds, 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 online slot 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 terms apply that say 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 PayByPhoneBillCasino.uk only recommend the top UK slots sites for no wagering bonuses – as this gives you the highest chance possible of turning our bonus funds and free spins 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 ONLINE 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 – even if your first deposit is low.

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 best 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 after the first deposit 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 beyond your free spins. This is because – if you read the terms apply smallprint – you’ll realise 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 an online slot machine on the move, the best slots online 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 online 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, redeem your bonus spins, speak with customer support, and of course – play online slot games!

HOW TO CHOOSE THE BEST SLOTS WEBSITES OF 2020?

Looking to get started with online slot games sites right now, but not too sure where to start? To help you along the way, you’ll find some handy tips on what you need to look out for when choosing an online casino.

If you don’t have time to perform research on your own and dig into dozens of lengthy ‘terms apply’ pages, why not consider one of the top-rated casinos that we have listed on this page? All of the casinos have been pre-vetted, so the hard work has been done for you – you can get straight onto using those bonus spins!

GAMBLING COMMISSION REGULATION

You must ensure that your chosen casino is regulated by the Gambling Commission. This is a minimum requirement in the UK slots space, so if the platform isn’t licensed – it’s operating illegally. Slot websites will always list their Gambling Commission license number clearly at the bottom of the homepage.

MASSIVE WELCOME BONUSES

Sites with the top online slots UK will always offer huge bonuses and free spins with no deposit. As noted earlier, this often exceeds 300% of your initial deposit amount. Some UK slot sites 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 as terms apply.

JACKPOT GAMES

If you’re looking to chase a life-changing win, make sure you choose a slot site that offers progressive slots on line. 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.

CUSTOMER SUPPORT

We only ever recommend the most trusted and very best slot sites that offer top-notch support. Good slot sites offer various support methods – such as live chat, email, and a toll-free telephone number. It’s also good when the slot site has a presence on social media. In doing so, it allows you to take your concern public if new players have a problem with free spins, bonus spins, wagering requirements, or any other aspect.

HOW TO GET STARTED AT THE BEST SLOT WEBSITES?

So that now that you know the ins and outs of how the best slot websites work, we are now going to explain what you need to do to get started right now.

Simply follow the guidelines listed below to start playing your favourite slot game!

Step 1: Choose the Best Slot Site for YOUR Needs

To get the ball rolling, you’ll need to choose a slot site that meets your needs. You can either review the section above on How to Choose the Best Slot Websites of 2020, or simply go with one of the top-rated slot sites we have listed on our platform.

Step 2: Quickly Open an Account

All of the best slot websites will ask you to open an account. The process takes minutes, and will simply ask you to enter some personal information. This includes your name, address, date of birth, and contact details. You’ll also need to choose a username, a strong password, and confirm you’ve read the online slot site’s wagering requirements.

Step 3: Verify Your Identity

As the UK gambling space is heavily regulated, online slot websites will ask you to verify your identity as part of their terms. This will require you to upload a copy of your passport or driver’s license, and a proof of address

You will either need to do this within 72 hours of opening your account, or when you first make a withdrawal (whichever comes first).

With that said, we at PayByPhoneBillCasino.uk would strongly suggest that you get this out of the way first. In doing so, you’ll avoid any delays when it comes to (hopefully) withdrawing your online slot winnings!

Step 4: Choose an Online Slot Machine

Once your casino account is funded, you can then choose a slot machine to play and start using any free spins or bonus funds you might have. The best slot websites will typically host at least 1,000 titles, so choice is vast. This will include video slots, classic slots, bonus slots, and even progressive slots.

If you have a particular online slot game in mind, you should be able to search for it. Alternatively, if you’ve got a certain developer in mind, you can also filter the online slot games down by the software provider.

Step 5: Set Stakes, Choose Paylines, and SPIN!

You need to set up your betting parameters. This includes the size of your stake, and the number of paylines in operation (if adjustable). Finally, click on the ‘SPIN’ button to get those reeling in action!

THE VERDICT?

With hundreds of reputable online casinos active in the UK online slot arena, knowing which platform to sign up with is no easy feat. As such, we hope that our PayByPhoneBillCasino.uk guide on finding the best slot sites of 2020 has helped clear the mist.

Crucially, you need to look out for key metrics when choosing an online slot site – including but not limited to regulation, customer support, software providers, payment methods, free spins, bonus funds, and of course – the number of slots!

The good news is that we have compiled the ultimate list of the best slot sites UK currently servicing UK players, so all of the hard work has been done for you!
