Our Top 5 Reasons To Play at the Best UK Slot Sites

Why do UK gamblers enjoy playing at the best slot sites? Clearly, because it’s all about both free and real money slots! You’ll find any kind of slot available here, in free or real mode, and to top it off, you’ll also get to enjoy your favourite slot games using a slots bonus.

We go through our top 5 benefits below, as narrowed down by our online casino experts:

Filter by Slot Type

Whatever slot variation you’re looking for, the best UK slot sites have it all. Discover branded slots, megaways slots, grid slots, and link & win slots, among others. Besides filtering by slot type, you can also narrow down your preferences by theme. Whether you’re into Ancient Egypt, pirates, or superheroes, you’ll find many slots available for each category.

Practice on Free Slots

At a best slot site you can also try popular slot games for free. Free slots give you a chance to familiarise yourself with the game mechanics, bonus features, and the paytable. It also allows you to figure out what slot variations, titles, and providers you enjoy before committing to a specific slot with your own cash.

Note: Remember that you must be over 18 years old when playing slots at UK sites, even if you’re trying them for fun.

Join a Slot Tournament

Slot tournaments are gaining popularity with UK players. The way it works is that you’ll compete against other players to be in the chance to win cash prizes, bonus money, or free spins. Usually, the online casino will choose a slot or a series of slot machines that you’ll have to play through. Top players end up on the leaderboard and win a share of the prize pool.

Find New Slots Sites

A good chunk of the best UK slot sites are also new slots sites. This means that not only will you find brand-new titles with high payouts available, but also a top user experience with great graphics, the newest instant and mobile payments, and up-and-coming slot providers. You’ll enjoy the latest trends in bonus features too, such as gigablox symbols and infinity reels.

Benefit From Slots Bonuses

When playing online slots at top sites, you'll benefit from slots-focused bonuses. This is a great advantage for slots players as at most casinos, video slots contribute 100% towards the wagering requirements. UK casino bonuses on slots can look like free spins on specific slot provider games, free spins on new titles, and prize drops on selected games.

Note: Always read the bonus terms and conditions to check whether there are any slot game restrictions on your bonus. For example, classic slots could have a wagering contribution of 75% at some casino sites.

How We Pick the Best Slot Sites for UK Players

When looking for the top online slot sites, we make sure they have a variety of the best UK online slots on offer. However, there are more criteria we take into consideration, such as site security, bonus offers, and instant payment methods.

Have a look at the factors we consider when choosing a top site below:

Licensing & Security

Licensing & Security

If you want to have player rights as a UK gambler, you must join a UKGC online casino. Slot sites regulated by the UK Gambling Commission have to stick to its rules and look out for their players, such as offering Responsible Gaming tools and problem gambling help. Something else we look out for is SSL encryption, to make sure that any information you send to the site is kept safe.

No Deposit Bonuses & Free Spins

No Deposit Bonuses & Free Spins

To get you started at the best online slots sites in the UK, we look for new player offers such as no deposit bonuses, which you can get as fixed cash or free spins. These bonuses allow you to try a new casino and its game lobby without risking your own cash. Other casino bonuses that you’ll benefit from after joining one of our suggested sites include cashbacks, no wagering bonuses, and reload offers.

Note: It’s worth noting that even though you don’t have to make a deposit to claim a no deposit offer, you’ll still need to deposit to be able to cash out any winnings.

Top Slots & Latest Releases

Top Slots & Latest Releases

A top online slot site will feature the most popular slots for British players. You’ll find iconic slot games like Starburst, Rainbow Riches, Book of Dead, and Cleopatra, among others. But if you’re looking for something brand-new, you can also try new online slots such as Microgaming’s Aztec Falls and Pragmatic Play’s Barn Festival. Keep an eye out for other leading game makers such as NetEnt, Playtech, and IGT.

Trusted Payment Options

Trusted Payment Options

Our recommended online slots sites feature a range of payment methods, from prepaid vouchers to e-wallets and pay by phone methods. Looking for a quick deposit method? Check out our top Boku casinos. Or do you prefer depositing and cashing out with the same banking option? Then head over to our suggested Neteller online casinos.

Note: While you’ll find many banking methods at top casinos, you should know that credit cards aren’t an option at UK sites. They’ve been banned for gambling since April 2020.

Customer Support

Customer Support

Even though you’ll have a seamless journey at the best slot sites, you might need further clarification on bonuses, deposits, winnings, and so on. This is where a great support team comes in, available 24/7 for any of your gambling needs. We also look for sites that offer support through many channels, including phone, live chat, email, and online message forms.

Our Recommended Best Online Slot Games for 2023

While video slots are the most popular games at the best UK online casinos, you’ll find other slot types on offer. These include classic slots, progressive jackpots, and megaways slots, among others.

We’ve gathered some of our top titles from different categories below, ranging from iconic titles to brand-new releases.

Our Expert Tip: You should only play slots online to have fun, not to win. Please gamble responsibly and seek help if feel like you’re developing a problem.

Mega Joker

A classic online slot from NetEnt, with a twist. While it features 3 reels and 5 paylines as with most classic slots, it also has a local, progressive jackpot. You’ll trigger the jackpot if you get 3 jackpot symbols in a row. This slot is also hugely popular thanks to its 99% RTP.

Wheel of Fortune Megaways

In this IGT slot game you’ll have up to 117,649 megaways to win. If you trigger the free spins with extending reels feature, this goes up to 1,000,000 megaways! Bonus features include megastacks and free spin retriggers. And if that isn’t enough, you also get an RTP of 96.46%.

Age of the Gods: God of Storms

This Playtech slot game is part of the wider Age of the Gods series. It’s an iconic one because of its RTP of 96.14% and the Wild Wind Respins feature. A ship wild fills up a whole reel and the reels respin, and continue to do so until the ship is blown off the grid. Win multipliers can go up to 5x!

Legacy of Oz

This Microgaming video slot has an RTP at 96.11% and a jackpot up to 5,000x your initial bet. You can also get up to 20 extra spins if you land 3 to 5 scatter symbols. Other bonus features include expanding symbols and respins.

Top Online Slots Providers at the Best Slot Sites UK

Most slot sites don’t make their own games, which is where slot providers come into play. These companies create the games software and then supply casinos with the latest and best slots.

How To Find the Best Slot Sites for Winning

How To Find the Best Slot Sites for Winning

While looking for top real money casinos in the UK, you should check the Return to Player (RTP) percentage for the slot machines on offer. This tells you how much money you’ll get back for every bet made.

For example, if you make a £100 bet on a slot with an RTP at 96%, theoretically you should get £96 back. And the higher the RTP, the more the slot will give back to its players. This is why our expert advice is to stick to casino slots with an RTP at 96% or higher.

Still, all of this is theoretical and there are more things to consider when playing for real. One of these is slot volatility, where slot games with high variance can give bigger wins. However, keep in mind that these wins might be less frequent. On the other hand, slots with low variance award smaller wins, but these are more frequent. So, for example, you might choose a slot with a high RTP and high variance, but due to the bigger volatility it might take a while (and money) until you reach the true RTP of the slot.

What’s more, some slot features can also affect your chances of winning. For example, most modern slot games allow you to choose the number of paylines you want to bet on, increasing your opportunities of winning. There are also slots with multiple ways to win, such as 243 ways to win. Also, you could win big on progressive jackpot slot games, even though their RTP is usually quite low. Just keep in mind that the odds of winning a progressive jackpot are minimal.

Discover the Best Mobile Slot Sites

Our top slot sites ensure that you can play the best games from any device, including mobile and tablet. You’ll also be able to spin on your favourite mobile slots for real money no matter which software you use, including iOS, Android, and Windows.

At the best mobile slot sites you can play in browser or through a downloadable gambling app. There are benefits to both, and which one you choose is mostly based on user preference. We give a brief comparison below so you can find the right option for you:

Mobile Browser

  • Can be accessed from any device
  • No limit to the number of slots you can play
  • Instant play, no need to download anything
  • You can only play with an internet connection
  • While gameplay quality is high, it still doesn’t match the sharpness of slots apps

Mobile Slots App

  • Very easy to navigate, and you can always continue playing from where you left off
  • Faster loading times than browser
  • You can play free slots without an internet connection
  • Not all casinos feature a mobile slots app
  • You need to download and install the app, which will take up space on your device
