The Biggest Slots in the UK

There's so much online slots choice out there in 2023, it's hard to know where to start.

That's why at, we cover the widest range of slots available. We review the biggest UK progressive jackpots slots that reward multi-million pound prizes every month, and tell where to find the leading software developers like Net Entertainment, Playtech and Microgaming.

Not all online casinos or slots are created equal, and you can soon find your bankroll disappearing before you realise that the bonus features are rubbish or the payouts stingy. That's why we'll lead you to the best-paying games on the net in 2023 that make your money go further.

Why Play Online Slots in the UK in 2020?

We could quite literally write a book about why you should play slots online. The main reasons are:

Range of Slots

If you've stepped into a big UK casino in London or Manchester, you'll have been impressed with the selection of slot machines available.

But you're always limited by floor space. There's no such worry online; with sites like you can find hundreds of slots games at the click of a mouse.

And, unlike a land-based casino, you can try out all our games absolutely free. Get a feel for the slot, try out the bonus features, then find a top online casino and put your money where your mouth is.

Software Providers

Land-based casino floors are often filled with slots from a handful of manufacturers. In contrast, hundreds of software providers fill online casinos with the best online slots. UK providers like Blueprint Gaming and Inspired Gaming have built a reputation for releasing fun, feature-filled vegas slots on a frequent basis.

Such variety promises to leave you spoilt for choice when you play slots online.

Best Odds and Payouts

It's also worth looking at the RTP (Return to Player Percentage) which slots pay out. This is the long-term, theoretical payout that a slot dishes out to players. While land-based slots struggle to push 90%, online slot games are more in the region of 92-97%. That's just another reason or new players to play slots online.

After all, playing slots with a high RTP means your bonus funds will last longer and you get more value.

Low Wagering Bonus Requirement

Welcome bonuses are another advantage of playing slots online. The best slots sites offer jaw-dropping deposit bonuses to get you to sign up and spin the reels.

However, there are T&Cs attached to your bonus funds. You will notice that the websites we recommend boast low wagering requirements, typically in the 25x-35x range.

This means you can quickly clear your wager and withdraw winnings.

How We Find the Best Slot Sites

Part of our mission at is to provide recommended slot sites for UK players. We have assembled a team of experts who scour the internet every day. Armed with a list of criteria as long as their arms, our experts rate each site they come across. The best casinos score high in these categories:

Secure Casinos

We would never recommend a slot site that we wouldn’t feel comfortable playing at ourselves. The best sites always hold a valid operating license. These sites also boast a lobby filled with games that have been declared fair by independent testing labs. Security protocols like SSL encryption and Two-Factor Authentication (2FA) should also be in place to ensure your personal details are never compromised.

The Range of Slots Available

Leading sites boast thousands of the latest and greatest online slots. You should find titles from big hitters like NetEnt and Microgaming, as well as ambitious studios like Nolimit City and Pragmatic Play. By offering slots from numerous providers, slot websites are guaranteed to have games that you enjoy. Whether that be classic slots or feature-filled video slots, our recommended slot sites have you covered.

Customer Support

While it’s highly unlikely that you’ll encounter any issues at sites listed on, problems can and do arise. We give high scores to slot sites that provide multiple support options for players. You should be able to get in touch with a friendly support agent via telephone, email or live chat in the blink of an eye. Slow response times and staff who are rude or lack knowledge result in us raising a red flag.

Free Spin Bonuses

The best online slots sites are renowned for dishing out free spin bonuses to new players. Some sites allow you to test their software with no-deposit bonus spins and bonus cash. Others throw in some bonus spins as a treat for making your first deposit. Many sites provide a list of eligible games that your bonus funds can be used on, with NetEnt’s Starburst being one of the most popular titles.

Free Practice Play

Another feature of the best slot sites is that they allow you to practice on slots before spinning the reels for cash funds. Sites that offer free practice typically have two buttons that can be clicked on when you hover over a thumbnail in the game lobby. One will be ‘play for free’ and the other will be ‘play for real money’. We also cover this with our ever-expanding free slots library, which boasts 10,000+ fun slots.

Payment Methods

You should be spoilt for choice when it comes to payment methods. Every leading slot site makes it easy for you to make your first deposit by providing a list of payment methods as long as your arm. Credit cards are no longer accepted at gambling sites in the UK. However, you should be able to fund your account via debit cards, e-wallets like Skrill and PayPal, prepaid vouchers, and even cryptocurrencies.

Advantages of Playing Online Slots versus Other Casino Games

If only we had a pound for every time players asked us why they should play online slots rather than other casino games. Why should I spin the reels of a vegas slot rather than a roulette wheel? Why play slots when I can follow a strategy and beat the dealer at the blackjack tables? These are all common questions. Our experts have identified four distinct advantages that online slots have over table games.

No Strategy Required- Playing vegas slots online isn’t rocket science. You simply browse the game lobby, select a slot that takes your fancy and spin the reels. Whether you win or lose boils down to pure luck, but you’re guaranteed to have lots of fun along the way. In contrast, casino games like blackjack and roulette are played while players follow complex betting strategies like the Martingale system.

Slots-Specific Bonuses- Have you ever noticed that a welcome bonus for new players is often only valid for slots? The universal popularity of vegas slots is the reason for this. Casinos are quick to dish out no-deposit bonus spins and bonus funds, but have you ever seen a site offering 25 free hands of blackjack or spins on the roulette wheel? No, because these games simply aren’t as popular.

Speed of Play- With a single spin taking just a couple of seconds to complete, online slots are perfect for a quick gaming experience. In contrast, live casino games take up far more time. You must wait for fellow players to place their bets and then for the result to be determined. You can spin the reels countless times in the time it takes Evolution Gaming’s Monopoly Live wheel to spin just once.

Life-Changing Wins Are Possible- A single hand of blackjack or spin on the roulette wheel isn’t going to transform your fortunes. However, one spin on an online slot could. Jackpot slots give you an opportunity to turn a small amount into millions. Yes, you would need to be extremely lucky, but it’s still a possibility. Mega Moolah and Mega Fortune have created numerous multi-millionaires over the years.

Play Online Slots on Mobile and Desktop

Whatever your platform, there's a range of slots just for you. You can enjoy slick graphics and fast gameplay on lots of devices, and many of the top titles cross over into multiple platforms.

Mobile Slots

With the evolution of mobile casinos, slots on your smartphone or tablet have never been so accessible. Developers are hurrying to adapt their popular online slots into versions that will work on a small touchscreen, but there's usually no loss of gameplay. Whether you're playing the big Microgaming progressives or a classic NetEnt title, there will be a decent version available for play on the go.


Every slot site worth its salt is optimised for iOS-powered devices these days. The latest iPhones boast large, all-screen LCD displays that make it even easier to play the best online slots on the go. Slick user interfaces make it easy to adjust your bet size, and these iPhone and iPad slots load instantly in your browser with no downloads required. As long as you have a solid internet connection, you’re good to go.


With Android releasing their latest operating system, and with games powered by HTML5, it's never been a better time to enjoy slots on your Android phone or tablet. Games can be downloaded to your phone or played via the browser; the choice is yours. Availability is one of the nicest things about Android slots. Whether you have a Samsung Galaxy or Google Pixel, you can fire up an Android slot.

Tablet Slots

If you don’t want to sit in front of your desktop or laptop but find your phone screen too small, why not play tablet slots instead? Whether you own Apple’s latest iPad or one of Samsung’s gorgeous Galaxy tablets, you will be able to play vegas slots online with zero issues. Slots instantly load in your web browser, and many sites even have dedicated apps that can be downloaded directly to your tablet.

Desktop Slots

Whether you're on a PC or laptop, thousands of the best online slots are available for free right now. Generally, games download via the web browser so you can enjoy the latest slots instantly. Games are normally powered by Flash or Java; perfect for playing on the web. A large screen and stable internet connection are just two of the many advantages of playing desktop slots versus your phone or tablet.

Mac Slots

While Mac users traditionally struggled with playing many Flash-powered games on their Apple machines, there's a much wider choice in 2020. And with the Mac's powerful processor you'll find hundreds of slot games that work on the latest MacBook. Not only do they work, they look incredible and provide an exhilarating gaming experience. Graphics are sharp and sounds are super realistic.

Types of Online Slots in 2023

Luckily, there's help at hand for players who think they might have a more serious problem. Expert resources in the UK like Gamblers Anonymous and GamCare, which provide support, advice, and free counselling to any British slots players looking for help.

Classic Slots

Once upon a time, a three-reel fruit machine was the best you could expect for a UK player. These days, you can still enjoy classic' 3-reelers with minimal pay lines and zero bonus features, like Bally's Quick Hit, but there's plenty more out there. These classic slots are always filled with fruity favourites like cherries and watermelons. They are typically low variance games, but they are fun and fast to play.

Jackpots Slots

The best thing about online slots is the huge progressive jackpots that can be won. Progressives take a small percentage of each bet placed and pool mega prizes across multiple casinos. This means you can win prizes worth millions of pounds if you trigger the right combination or bonus feature. Check out Microgaming's Mega Moolah or NetEnt’s Mega Fortune for two of the biggest prize payers of 2020.

Video Slots

Video slots boast five or more reels and upwards of 20 pay lines. Developers like Microgaming broke the mould by introducing slots with 243 and 1,024 ways to win, but providers like Big Time Gaming have since taken things even further with their powerful Megaways engine. Video slots are filled with exciting bonus features like bonus spins, pick’ em games and bonus bet options to deliver something for everyone.

Skill-Based Slots

The lines between slots and video games are starting to blur. In 2020 you can see slots emerging online that feature 'skill' bonus features that involve target practice or navigating a maze in order to win a cash prize. A prime example of this is Gamomat’s Crazy Chicken Shooter series. This jackpot side game gives you a chance to put your shooting skills to the test by shooting chickens that flap across the screen.

3D Slots

If you like the idea of animated characters coming to life across the reels, then you’ve simply got to try some 3D slots. Providers like Betsoft and Netent are renowned for introducing us to lovable characters and taking us on exciting adventures. A captivating story usually accompanies 3D slots to immerse you in the theme. These spectacular slots are also jam-packed with exciting features like wilds and bonus spins.

VR Slots

For a truly immersive gaming experience, why not slip on a VR headset and try virtual reality slots? As technology continues to advance at an incredible rate, more and more software providers are investing in the development of VR slots. NetEnt has already blown us away with a virtual reality version of their Gonzo’s Quest slot. We expect many more VR slots to be released soon, so get your Oculus Rift ready.

How to Win When Playing at Slot Sites

There is no magic formula to winning when it comes to playing vegas slots online. If there was, we could all spin the reels, get filthy rich and retire long before we think about growing old. While slots are mainly reliant on luck, our experts have compiled five tips to help you increase wins when playing slots online.

Tip #1 – Take Advantage of Bonuses

Almost every slot site will welcome you with a generous bonus. Not all bonuses are equal, though. While some sites offer no-deposit bonus spins or chips, others stick to tried-and-tested match bonuses. We would encourage you to look for sites that offer non-sticky or parachute bonuses. With these bonuses, your bonus funds only come into play if you lose your initial balance, thus giving you a chance to avoid wagering.

Tip #2 – Play Slots with a High RTP

Why give yourself a disadvantage by playing vegas slots with a low RTP? Every online slot is already programmed in the casinos favour, so don’t kiss goodbye to your money quicker than you have to. A slot with an RTP of 97% means that you will, theoretically, receive £97 for every £100 you wager. If you play a slot with an RTP of 92%, you are going to burn through your balance and need to redeposit far sooner.

Tip #3 – Avoid the Gamble Feature

You may be tempted to click on the ‘gamble’ button that flashes after winning combinations, but our experts advise against doing so. You will see gamble buttons when you play online slots from the likes of Novomatic and Microgaming. They come in many forms – cards, coins, ladders, wheels, etc. You basically gamble your winnings in the hope of doubling or quadrupling them. It’s a recipe for disaster.

Tip #4 – Don’t Hunt for Jackpot Wins

Trust us, we know how difficult it is to scroll past an online slot boasting a life-changing jackpot worth many millions. However, the reality is that jackpot slots are notorious for their low RTPs. A prime example of this is Microgaming’s famous Mega Moolah slot. It has an RTP of just 88.12%, which suggests base game hits are few and far between. Unless you have a large balance, it’s best to avoid these slots.

Tip #5 – Does the Slot Have Potential?

Ask yourself this question every time you load an online slot. Our experts can’t emphasize how important it is to study the pay table before spinning the reels. Being informed about how much symbols pay and how the bonus rounds work allows you to gauge whether big payouts are a possibility. If you have your sights set on a 5,000x your bet win, a slot capped at a measly 1,000x isn’t going to cut it.

Responsible Gambling

Playing slots online is a fun and frantic pastime, but involves betting real money. While the majority of players can gamble without getting into trouble, for a small percentage their gambling can get out of hand.

Sensible gambling on a basic level is about managing a bankroll. It means never gambling more than you can afford to lose and setting yourself loss (and win) limits where you stop playing and switch off the PC.

Luckily, there's help at hand for players who think they might have a more serious problem. Expert resources in the UK like Gamblers Anonymous and GamCare, which provide support, advice, and free counselling to any British slots players looking for help.

Are online slot sites and online slots rigged?

This has been one of the biggest slot machine myths since the very first online slot was released decades ago. Some players believe online slots are programmed to pay out in regular cycles. Truth be told, every spin is independent, and the outcome of previous spins has zero bearing on the next spin. Online slot sites are regularly audited by regulators. They would never risk their license and reputation by cheating.

Are online slots worth it?

They certainly are. Online slots have many advantages over other casino games and land-based slot machines. For starters, you can spin the reels from the comfort of your own home. Payouts for online slots are also substantially superior. Another reason to sign up and deposit at online slot sites is that they welcome you with bonus spins and a match bonus as a reward for giving their site a try.

Which of the best online slots payout the most?

Great question! By making optimal bets, you can play NetEnt’s famous Mega Joker slot with a staggering payout percentage of 99%. Another NetEnt slot follows closely in second place – Jackpot 6000, which boasts an RTP of up to 98.8%. Other online slots with an incredibly high payout include 1429 Uncharted Seas by Thunderkick (98.6%), Joker Strike by Quickspin (98.11%) and Blood Suckers by NetEnt (98%).

What are the best online slot sites?

Good luck finding better online slot sites than those listed here at Our experts have spent countless hours scouring the internet to bring you a list of the best slot sites for winning players. We don’t rest on our laurels, either. We review the newest sites that accept players from the UK to see if they bring anything new to the table. If they do, we add them and negotiate a juicy bonus for you.

Can you win money playing online slots?

You can indeed! However, it’s important to understand that online slots are programmed to take more money than they pay. This is why you’ll never see an online slot with an RTP of more than 100%. The good news is that new players have turned small deposits into large cashouts simply by spinning the reels. Just look at the many jackpot winners who have turned a minimum deposit into millions.
