How We Rank UK Online Slot Sites

Our experts have reviewed and rated the top slots sites in the UK. The best casino sites are then ranked according to how well they meet our strict criteria, which include being 100% safe, secure, and licenced by the UK Gambling Commission. Here are other important factors we consider when compiling our rankings.

Safety and Reliability

All casinos we recommend are 100% safe and reputable. Whether it’s big-name brands or the best new slot sites in the UK, you can rest assured that all are licenced and regulated by the UK Gambling Commission. We only rank casinos that use the latest Transport Layer Security (TLS) encryption and firewall software.
Slots Quality and Quantity

Our experts consider the range of slot games available at each of the online slot sites we recommend. We also look at the quality of the casino software to ensure titles from big-name brands are available. While the slots available at sites may differ, the quality and quantity of games should be consistent.
Software Providers

We only recommend betting sites with slots from the best software providers in the game. This includes Microgaming, NetEnt, Blueprint Gaming, IGT, and more. You may also find boutique creations and even titles more popular on non UK slot sites. In addition to Mega Moolah and Cleopatra, you’ll get more than a fleeting chance to play something different.
Bonuses and Offers

Promotions like welcome offers and free spins are ubiquitous at popular slots sites. That may be the case, but our experts always take into account how good a site’s online casino bonuses are before compiling our rankings. Online casinos that offer top match slots promos for slot players – including bonuses that aren’t heavily restricted by wagering requirements on eligible games – are favoured.
Customer Support and Payments

In addition to all of the above, we ensure the sites we recommend have top-quality customer support. A wide range of deposit methods should be offered by slot casinos, meaning you have more choice over the debit cards, e-wallets, and other banking options you want to use. We favour instant withdrawals but will settle for sites that pay out in 24 hours where possible.

Different Types of Slots You Can Play Online

The best slot sites in the UK are stacked with countless games and titles. Almost every single slot machine in the world can be assigned to a particular category, such as themed or jackpot slots. Here’s a closer look at what these categories entail.

Video Slots

All online slot machines are video slots – at least, technically. The range of games available on sites are all digital and decided by random number generator (RNG) software. But most 3-reel to 6-reel video slots – such as Big Bass Bonanza, Book of Dead, or Gladiator – have better graphics, themes, pay lines, and features when compared to classic slots.

Classic Slots

Often simpler and reminiscent of older, mechanic slot casino games, classic slots are still popular. You might find online slot sites with modern video slot games stocking classic titles, too. These titles, such as Couch Potato or Lucky 7, often feature one reel with one pay line and no bonuses or extra spins available to win.

Jackpot Slots

Many online casinos have a selection of jackpot slots you can play. Slots with standalone jackpots pay a top prize for matching particular symbols – these can also be paid in bonus rounds. Unlike progressive jackpots, the top prize on standalone jackpot slots is set at a particular figure. This may be expressed as 25,000x your line bet or 10,000 your total bet.

Progressive Jackpot Slots

Many players dream of winning the top prizes on progressive jackpot network slots, as these can often be life-changing sums of money. Games on the Microgaming Mega Moolah jackpot network – as well as Hall of Gods or Jackpot King titles – can often pay millions of pounds when you land the first prize.

Themed Slots

All gambling sites for UK slots players have themed slots available to try. Good examples of themed slots are Cleopatra (ancient Egypt) and Rainbow Riches (luck of the Irish). Other popular themes include animals, mythological creatures, and Chinese folklore. There is a wide variety of slots at casinos with themes similar to what you would find at Las Vegas casinos.

3D Slots

3D slots, which are also widely available at slots sites, offer a more immersive playing experience. In short, 3D slots come with crisper graphics, cinematic sounds, and the presence of 3D graphics. Some of the most famous 3D slots include Jurassic Park, Big Bass Splash, and Finn & the Whirly Spin.

Branded Slots

These slots are commonly based on films, games, bands, books, and celebrities. Software providers must request to use the intellectual property and pay for the privilege of doing so. Jurassic Park, which we mentioned when talking about 3D slots, is also a branded slot. Other branded slots include Guns N’ Roses, Gladiator, Family Guy, Scarface, and Batman Returns.

Megaways Slots

Slots with Megaways work differently from most of the above. First, they are built on software with random reel modifier mechanics that can pay for matching symbols in 243 to 117,649 ways. The enhanced ways to win mean that players can potentially enhance returns on slots including Big Bass Bonanza, Diamond Mine, and Wild Portals Megaways titles.

Other Slot Types

Playing slots online hasn’t changed a great deal over the past decade or so. But there have been some creations and innovations that have popped up.

Fruit Machines – Online fruit machines are digital recreations of the types of “bandits” you usually find in certain pubs and land-based casinos across the country.
Retro Slots – Many retro slots are online impressions of older slot types and may lack the visuals, graphics, and features of modern titles. Where you find them ultimately comes down to game availability.
Cluster Pay Slots – These types of casino games go against the tried and tested reels format, instead paying out for “clusters” of the same symbol. There are plenty of cluster slots in the average casino game collection.
Proprietary and Exclusive Slots – Although rarer in the UK, proprietary slots do exist. More common are exclusive slots; these games can only be played at specific sites that acquire the rights for them.
VR Slots – The concept of playing slots in virtual reality is now very real, with VR slot games available online. We are unaware of trusted, UKGC-licenced sites offering them right now, however.
Provably Fair Slots – Provably fair slots are extremely basic games usually found at crypto slot websites, depending on their game availability. These slots don’t tend to have bonus features or enticing graphics and are not created by major software developers.
Live Dealer Casino Slot Games – Many live dealer games today are based on popular slots like Gonzo’s Quest and Deal or No Deal. There is a wide variety of games under this banner you’ll find in live casino lobbies. But they work different from most slot types.

How to Join Online Slot Sites in the UK

Here's how to join a new slots site in five easy steps.

Visit the Site You Want to Join

When you have made up your mind about where you want to play, head on over to the site to get things started.
Select the "Join Now" or "Register" Button

It takes around five minutes to create an account with our recommended slot sites. When you hit the button to join, a simple online form will present itself to you. Fill out the form to register with that casino.
Select Your Bonus

Make sure you have followed the necessary steps to claiming your welcome bonus or free spins with the site. If you are unsure, reach out to customer support for assistance before you finish this process.
Add Your Payment Method

You'll need to add a banking option and make a deposit before you can play real money slot games. Make sure the method you choose is compatible with claiming bonuses on the site.
Play Your Favourite Games

When you have completed all four steps above, you should be ready to go. Have fun!

Tips for Choosing the Best Online Slot Sites UK

The popular slots sites among our experts are those that simply do things better than their rivals. When looking for top sites, we recommend following this advice to ensure you’re making the right choice every time.

Pick Sites with Quality Slot Games

Whether you’re looking for a casino site with progressive jackpot slots or video slots from your favourite developer, keep quality in mind. You can find sites with the best slots by browsing through games libraries before you join. This may save you any frustration or disappointment further down the line.

Choose Sites with Good Bonuses

There is a wide range of online casino bonuses and ongoing promotions available to slot players that ultimately differ in quality. Good bonuses provide the chance to win something without dealing with excessive initial deposits, deposit limits, or short dates of expiry from making deposits. Compare wagering requirements and opt for the best deal with the fewest restrictions.

Target Casinos with Large Slot Libraries

More doesn’t always mean better. But when it comes to slots, whether it’s progressive jackpot slots in the UK or simply the number of 3D titles available, it almost always does. Sites that have more slots cater to more players. Whether it’s Double Bubble or Cleopatra 2, playing at online casinos with larger collections provides more scope to find what you’re looking for.

Consider Banking Options and Withdrawal Times

In theory, you might find a casino with a quality interface, great bonuses, and a huge selection of games. But if their deposit methods are few and withdrawal times excessive, this can put a real dampener on your fun. Always check both before you join to avoid disappointment – also, make sure that the method you choose to pay with is eligible for bonus offers!

Never Play at Untrustworthy Sites

We only recommend sites licenced by the UK Gambling Commission that have been verified to be safe and trustworthy. If we don’t trust a site, we disregard them completely and move on. Playing with sketchy sites means running the risk of having spin winnings withheld and personal information compromised – for this reason, you should instead opt for sites proven to be legit.

Top Slots You Can Play at UK Online Casinos

Our recommended online casinos are stacked with classic slots, 3D slots, and jackpot slots for UK players. But we like to see the most popular online slots covered as much as possible. Here are some recommendations for the best slot games you can play at UK sites.

Book of Dead

Software Provider: Play’n GO
Minimum/Max Stake: £0.10/£100
Release: 2016
Theme: Ancient Egypt; Adventure
RTP: 96.21%

Also known by its complete title, Rich Wilde and the Book of Dead, this classic is up there with the UK’s favourite slots of all time. Inspired by the Indiana Jones film franchise, the game has excellent graphics and is easy to play. The bonus round features expanding icons that can lead to top payouts.

Rainbow Riches

Software Provider: Barcrest (SG Digital)
Minimum/Max Stake: £0.10/£100
Release Date: June 2009
Theme: Luck of the Irish; Leprechauns
RTP: 95%

Barcrest’s beloved leprechaun slot is still going strong, despite other slots of its time falling into obscurity. The original Rainbow Riches should make any A to Z of slot sites’ favourite titles to play – especially when you consider its multiple bonus features. There are also multiple spinoffs in the series which are equally as fun.

Eye of Horus

Software Provider: Blueprint Gaming
Minimum/Max Stake: £0.10/£50
Release Date: September 2015
Theme: Ancient Egypt
RTP: 96.31%

Many of the best UK slots sites have Eye of Horus, which may not initially strike you as a compelling game. But it’s certainly got a lot of character; this is perhaps best emphasised in the free spins bonus round. Upgraded symbols can pay out serious cash, helping to make this a very coveted game indeed.

Big Bass Bonanza

Software Provider: Pragmatic Play
Minimum/Max Stake: £0.10/£100
Release Date: December 2020
Theme: Fishing
RTP: 96.71%

The original Big Bass Bonanza just may be the best of them all. Released online in 2020, the game has since gone on to spawn several sequels with themes varying from trucks to ghouls. Pragmatic Play is the team behind this one, which is also part of the Drops & Wins network available at popular slot sites.

Mega Moolah

Software Provider: Microgaming
Minimum/Max Stake: £0.25/£100
Release Date: November 2006
Theme: African Safari
RTP: 88.12%

Widely regarded as one of the best Microgaming slots of all time, Mega Moolah is also considered one of the best progressive slots ever made. The game has created several overnight millionaires, with jackpots sometimes paying into the tens of millions. We are confident in saying that no other jackpot network can match slots in the Mega Moolah series for payouts.

Gonzo’s Quest

Software Provider: NetEnt
Minimum/Max Stake: £0.20/£50
Release Date: November 2011
Theme: Adventure; Conquest
RTP: 95.97%

NetEnt is responsible for some of the most groundbreaking slots of all time, and Gonzo’s Quest is the perfect case in point. This is the very first game where the beloved Cascading Reels feature found its home, providing a unique gaming experience. The main character is loosely based on the legendary Spanish conquistador Francisco Pizarro and his brother, who were responsible for conquering the Inca Empire.

Cleopatra

Software Provider: IGT
Minimum/Max Stake: £0.20/£100
Release Date: January 2009
Theme: Ancient Egypt
RTP: 95.02%

Originally found in land-based casinos around the world, Cleopatra’s arrival in the online playing sphere was greeted positively. The game, created by IGT, is now one of the most revered slots ever made. The bonus round pays x3, making for some potentially juicy prophets, with the chance for a max bonus of 180 retriggers possible.

Starburst

Software Provider: NetEnt
Minimum/Max Stake: £0.10/£50
Release Date: November 2012
Theme: Jewels; Space
RTP: 96.09%

Another NetEnt classic, Starburst is still considered a masterpiece. While modern video slots and progressive jackpots are the titles most worth talking about these days, this 2012-released title keeps simple. So simple, in fact, that there is no free spins or bonus round present. You do, however, get some excellent graphics and one of the most innovative uses of wilds and extended respins in slots history.

Immortal Romance

Software Provider: Microgaming
Minimum/Max Stake: £0.25/£50
Release Date: December 2011
Theme: Vampire; Gothic
RTP: 96.86%

Microgaming’s Immortal Romance is another very important slot. Upon its release in 2011, most were taken aback by its comprehensive bonus structure, eye-catching graphics, and overall gaming experience. It has certainly aged well, with many desktop and mobile casino slot sites proud to display it among their most popular titles.

Dead or Alive 2

Software Provider: NetEnt
Minimum/Max Stake: £0.10/£100
Release Date: April 2019
Theme: Wild West
RTP: 96.82%

Western-themed slots grew in popularity off the back of Dead or Alive 2. The first in the series was certainly influential, but not to the same degree as its successor. With scatters, free spins, and various bonuses to choose from, it’s no wonder that players continue to seek this one out.

Best Online Slots Sites Bonuses to Claim

There are several online casino bonuses you can claim at online slot sites in the UK. The most common are match bonus deals and free spins. It is pretty common for online casinos to provide combinations of match bonuses and bonus spins, as well as other common casino offers and regular promotions. Max cash that can be claimed from deposit bonuses and other offers depends on the casino’s terms and conditions.

Free Spins – It’s always worth comparing slots sites with free spins offers to find the best deal. Many online casinos give you a certain number of free spins as part of their deposit bonuses, which usually come with bonus wagering requirements. Others have no wagering on spin winnings/bonus money.
Match Bonuses – Regular promotions include deposit offers like match bonuses, which give you casino cash to play with based on your first deposit. The maximum bonus is usually capped, with bonus funds wagering requirements usually applicable. Game weightings and game contributions may also apply.
Reloads – Similar to match bonuses, these are usually available when making your 2^nd Sometimes available on subsequent deposit offers, reloads also carry terms and conditions – such as 50x wagering on deposit or wagering 40x deposit and bonus funds.
Existing Customer Offers – Some of the best slot sites bonuses are available to existing customers. These include bonus bets to use after your active bonus, such as free spins, casino cash, or even cash prizes. Both new slots sites in the UK and more established casinos should have existing offers alongside offers for your 1st deposit.
No Deposit Bonuses – Admittedly rarer than they used to be, no deposit bonuses are still available in some cases. We have come across existing customer no deposit bonus bets and bonus funds far more frequently than those aimed at new players. Max cash withdrawals from these offers is usually smaller when compared with other offers.
VIP Bonuses and Loyalty Programmes – Some online casinos allow players to earn bonuses for joining loyalty schemes. Other times, they can claim larger offers by depositing more over a specified period, or even against one-time deposits. Entry to exclusive slot tournaments may also be offered.
Cashback Deals – We are aware of several sites offering rebates and cashback bonuses to both new and existing customers. These bonuses work by kicking back a percentage of your net losses to you periodically, and may be based on 1st deposits and/or lifetime deposits. Stake contributions may differ depending on the slots you play.

Top 5 Sites with the Best Free Spins Offers

Free spins, also known as bonus spins or extra spins, are offered by casinos as part of welcome packages. Bonus spins may also be provided to new customers as part of ongoing promotions. Here are our five favourite sites offering extra spins to players who sign up for an account with them.

Casino	Free Spins Offer	Bonus Wagering Requirements	Minimum Deposit	Free Spins Expiry
	80 Free Spins	None	£10	3 Days
	20 Free Spins	None	£10	24 Hours
	100% up to £200 + 20 Free Spins	50x	£10	7 Days
	Up to £100 + 100 Extra Spins	35x	£20	7 Days
	100% up to £50 with 100 Free Spins	35x	£20	7 Days

Online Slots with Highest RTPs

RTP is expressed as a percentage and is defined loosely as what the machine theoretically pays out over time against the portion of bets placed. The higher the RTP, the more it has been programmed, in theory, to return to you. Therefore, we recommend targeting slots with high RTPs, such as these.

Rank	Slot Title	RTP	Provider	Where to Play
1	Book of 99	99.0%	Relax Gaming	PlayOJO
2	Mega Joker	99.0%	NetEnt	All British Casino
3	1492: Uncharted Seas	98.6%	Thunderkick	Leo Vegas
4	Bloodsuckers	98.0%	NetEnt	Yeti Casino
5	Jokerizer	98.0%	Yggdrasil	MagicRed
6	Kings of Chicago	97.8%	NetEnt	21LuckyBet
7	Starmania	97.8%	NextGen Gaming	HeySpin
8	White Rabbit	97.8%	Big Time Gaming	Winomania
9	The Wish Master	97.7%	Betsoft	Casiplay
10	Devil’s Delight	97.6%	NetEnt	PlayOJO

Leading Slots Software Providers

Our favourite UK slots sites stock all kinds of popular slot games from the biggest slot providers in the world. As online casinos must acquire special licences to use game software, it’s always a good sign to see a wide range of providers on sites we review.

There are hundreds of slot websites featuring exclusive games and mobile versions of the leading titles in the world. Here are some of our favourite developers you’ll find at our favourite casinos.

NetEnt

Founded in 1996 in Sweden, NetEnt soon became one of the true pioneers of online casino software development. The company is regarded worldwide for its innovative approach to creating video slots, with some of the greatest games of all time carrying its brand. Starburst, Gonzo’s Quest, and Bloodsuckers are some of the best NetEnt slots to sample.

Microgaming

One of the true heavyweights of the slots world, Microgaming’s roots stretch back to 1994. The company is synonymous with jackpot slot games, thanks to Mega Moolah (arguably the best Microgaming slot there is). The company, which is a huge player in the iGaming sphere, also created classics such as Immortal Romance and Jurassic Park.

Blueprint Gaming

Masters behind classic slots such as Eye of Hours and Fishin’ Frenzy, Blueprint Gaming was established in 2001. The UK-based company continues to deliver some of the most desirable slots in the industry, with Primal Megaways and Ted among some of the most played games at UK online casinos.

Pragmatic Play

Although Pragmatic Play is a relative newcomer to the iGaming business, their output since being founded in 2015 has been phenomenal. Perhaps their greatest creation thus far is the Big Bass Bonanza series, but they are also responsible for smash hit slots such as Wolf Gold and Gates of Olympus – not to mention their Drops & Wins feature.

Play’N GO

Founded in 2005, Play’N GO is another major contributing factor to the success of the iGaming industry. Best known for its Book of Dead series, other top slots the company has produced include Ractoonz and Scroll of Seth. The company is considered one of the more forward-thinking players in the global gambling industry.

More Leading Slots Software Providers

Many slots players develop their favourite software providers in time. Here are some other software providers to keep in mind when playing at online slots sites.

IGT – Iconic online slots specialists behind classic titles such as Cleopatra, DaVinci Diamonds, and Pharaoh’s Fortune. Like all developers on this list, IGT games can be found at our recommended sites with slots.
Playtech – The world’s largest online casino software and content provider, Playtech are the masterminds of top hits like Age of the Gods, Kingdom’s Rise: Guardians of the Abyss, and Buffalo Blitz.
Yggdrasil – One of the finest online casino software developers in the game. You may recognise Yggdrasil from titles like Valley of the Gods, Double Dragons, and Super Heroes among many others.
Novomatic – Wildly successful in both land-based slots casinos and in the online realm, Novamatic are the brains behind fan favourites such as Book of Ra, Lucky Lady’s Charm, and Dolphin’s Pearl Deluxe.
Realtime Gaming – A prolific slot developer, Realtime Gaming’s library is stocked with standout games like Spirit of the Inca, Cash Bandits 2, Aztec’s Millions, and more. You can find their best titles at the leading online slot casinos, subject to game availabilty.

Top UK Online Mobile Slots Betting Sites for 2024

Many slots enthusiasts enjoy spinning from their smartphones and other mobile devices. If you’re looking to play the best mobile casino slot games, we recommend the following online casinos.

Advice and Tips for Playing Online Slot Games

Wondering how to play online slots? If so, we have some tips to help you get started. Everyone begins in the same position of unfamiliarity, so it’s always best to plan your steps carefully if you want some kind of advantage. The following advice will help when playing slot games at a new casino.

Only Play at the Best Slots Sites

Why not start by comparing the top 10 slots sites in the UK, as recommended by our experts? If you’re feeling even more adventurous, discover the other online casinos we have rated. These sites have made our rankings because we believe they are, quite simply, the best when playing slots on mobile in the UK.

Learn Different Features and Rules

There are thousands of slot machine games online. While almost none require application of skill, they may have different rules to learn. It’s important to understand these rules, whether it be eligible stakes for the jackpot to learning how to change your coin value without compromising your chances of winning.

Look for Slots with High RTPs

Most software developers publish the return-to-player (RTP) ratios of their slots. If you are looking for slots that pay the most back, at least in theory, it’s better to target games with higher RTPs. While RTP is a theoretical means of judging the returns from playing a slot over a very extensive period, it can give us some idea of which slot games pay out more.

Take Advantage of Bonuses and Free Spins

It’s unrealistic to claim every single promotion out there; as such, comparing deposit bonuses and other offers is a good idea. You can find a wide range of different offers and bonus spins new slot sites in the UK with no deposit required, sometimes. Match bonuses, deposit bonuses, and regular offers are also available at popular slot websites.

Have Fun

Playing slots, just like any other gambling endeavour, should be for enjoyment purposes. While you can certainly win money playing slots, you can also lose your hard-earned cash – treating gambling as a way of funding your lifestyle is not a good idea. For this reason, you should prioritise having fun over making a profit as slots have some of the highest house edges at online casinos.

Biggest UK Slot Wins of All Time

Slots betting sites have paid out some gigantic prizes to lucky slots players over the years. Many of the largest wins ever recorded have been paid out to UK players – many coming from casino sites with progressive jackpot slots.

How to Gamble Responsibly When Playing Slots

Choose Safe Slot Sites in the UK

One of the most crucial aspects of gambling responsibly is choosing where you play. That’s why it’s important to choose the sites you gamble at wisely, making sure they are safe, secure, and licenced by the UKGC. Playing at unsafe casinos can lead to losses of money, personal information, and more.
Only Spend What You Can Afford to Lose

The golden rule of gambling is to only bet with money you won’t miss when it’s gone. When we get caught up in the thrills of playing at online slots websites, we can lose sight of logic. This may lead to betting with funds that should be allocated to important stuff, such as rent, mortgage repayments, and other important outgoings.
Take Regular Breaks

One of the best ways of avoiding compulsive betting behaviour is to step away and give yourself a breather. Instead of praying incessantly to the slot gods for that bonus trigger, why not stand up and take a short walk? Taking regular breaks is a healthy way to curb the development of problem gambling patterns.
Set Stop Limits and Never Chase Losses

You can set stop limits for both losses and wins. The usual stop limit for losses is when your bankroll has been used up – for wins, you might want to consider taking your money when you win double your bankroll. Stop limits help you avoid chasing losses, which is one of the worst things you can do when gambling.
Make Use of Other Gambling Controls

Most online casinos provide assistance and tools designed to help you control your betting activity. These are usually found in a specific part of your account – in addition to setting deposit limits, timers, and breaks, you can choose to self-exclude or even close your account. There may also be links to gambling help organisations like GAMSTOP and GamCare.
