There are a lot of topics related to online slot games that I decided are worthy of a dedicated article, due to the depth and breadth of the theme. You can take your time to read through these pages by clicking through on the topic of interest below.
Some of the Most Popular Slots to Try
It’s difficult to a complete overview of the best real money slots on the UK market, as there are so many out there. So, without further ado, here is a complete list of the top 99 most popular and most played online slots. Browse them in any order you please, or click through for a full individual game review and best slots casinos for each title.
The Highest Real Money Slots Payout Rates
The return to player (RTP) of an online slot game is one of the most important things to understand when trying to select from the thousands of options out there. This figure, described as a percentage, provides an indication of how much of the wagered money will be paid out over an extended period of time. Directly related to the chances of winning, the closer to 100%, the better.
|Slot Machines with the Highest Payout rates|
|#||Online Slot||Payout||Paylines||Developer||To the Casino|
|1||Big Bad Wolf||97,35%||25, fixed||Microgaming||Betway|
|2||Jack Hammer 2||97,1%||99, fixed||NetEnt||Netbet|
|3||The Classic 243||97,00%||243, fixed||Microgaming||Betway|
|4||The Dark Knight Rises||97,00%||243, fixed||Microgaming||Betway|
|5||Reel Rush||97,01%||3125, fixed||NetEnt||NetBet|
|6||Wild Gambler||97,00%||20, fixed||Playtech||Ladbrokes|
|7||Guns N Roses||96,98%||20, fixed||NetEnt||NetBet|
This table provides a great look at the best online slots games and suggests a leading casino where you can play it right now for real money. You’ll see that no jackpot games are included on the list, which is not surprising as these types of slots usually have among the lowest RTPs, to balance the fact that they sometimes pay out enormous sums of money. I’ll explain how RTP rates are tested later on the page.
Games With High Maximum Wagers
Of course, one of the main reasons UK gamblers love to play slots for real money is the potential for winning fat stacks of cash. The different games will have individual ways of working out how much they pay out, but the general rule is that the higher the wager, the higher a winning payout. The lowest bets you can place is 1p per line, while some of the higher limits are much higher – I’m talking up to £5,000 per line. The table below highlights some of the best slot games with high maximum bets, and the sites where you can find them.
|Online Slot Machines with the Highest Betting Limits|
|#||Online Slot||Max Bet||RTP||Developer||To the Casino|
|1||Bounty of the Beanstalk||£500||94,00%||Playtech||BetVictor|
|2||Rainbow Riches Free Spins||£500||95,00%||Barcrest||BetVictor|
Unsurprisingly, one of the many benefits to playing slots online is that the limits are much wider than in a land-based casino. It is important to set your own budget of how much you are willing to bet for each spin and check carefully before every turn to make sure you have selected the right amount.
The Best Slots Loved at UK Casinos
When choosing which slot to play online, do you pick the most entertaining, or the one with the biggest prizes? Well, there are actually plenty of games where both factors go hand in hand. With that in mind, here are the best slots sites will have in their portfolios, which are not only fun to play, but also have some impressive jackpots.
Mega Moolah – The Millionaire Maker
This famous game from the world-renowned software developer, Microgaming, has paid out millions of pounds throughout its history. In fact, it became a Guinness World Record holder in 2015 when a player won €17,879,645.12 (£15,859,739.44), then broke its own record in 2018 with a €18,915,872.81 (£16,779,768.89) prize paid out. The African safari theme features bright and colourful cartoon style animal symbols, reminiscent of The Lion King. There are four progressive jackpots available, which can be won in a spin-the-wheel bonus round.
The largest of the four prizes, the Mega progressive, is always guaranteed to be a minimum of £1 million. Of course, the life-changing progressive jackpot is the biggest draw of the game, but there are plenty of other rewarding features. These include double payouts with wild wins plus free spins, where all wins are tripled. This millionaire-making slot machine can be played at all casinos that host Microgaming software. My recommendation is Betway, where Mega Moolah can be found alongside more than 770 other great slots.
Mega Fortune – The Glitzy Slot with a Huge Progressive Jackpot
The theme of this spectacular NetEnt title screams wealth and glamour. Mega Fortune is dripping with bling, yachts, stretch limos, jewellery and champagne – and the theme perfectly matches the legacy of the slot. It has held the world record for the largest online slot payout twice. The biggest prizes can be won during the bonus round, where there are three jackpots and various cash prizes up for grabs.
When you line up three bonus symbols, you enter the jackpot game where you can spin the three-stage wheel of fortune. Each spin gets you one step closer to the inner wheels and the bigger prizes. Make it all the way to the centre and you’ll walk away with the impressive Mega Jackpot. This progressive jackpot builds and builds until it is won, usually worth in excess of millions. You can play this captivating game at Mr Green.
Reel Rush – Modern Classic
This is one of the more innovative titles you’ll find online. When you launch it, you’ll see that some on the spaces at the corners of the reels are inactive. Every time you get a win, a re-spin is triggered, and two of the inactive spaces are opened up, increasing the number of ways to win. Each consecutive win triggers another re-spin, with even more ways to win. When you get another win after five consecutive re-spins, eight free spins are awarded and all of the hidden spaces on the reels become active. This opens up a massive 3,125 ways to win. Now, as you can imagine, this is where you will see the biggest payouts.
In fact, you can pocket up to 480,000x your bet. This innovative and unconventional gameplay builds up the excitement and anticipation with every single spin. It features superb graphics and mixes the style of classic console games with modern arcade style games. There’s also a funky soundtrack, again adding to the fun factor. You can try out this unusual slot, both for free and for real money at 888casino.
Starburst – Consistent Choice
This video slot from NetEnt became an instant hit with players. It is visually stunning, with bright, vibrant colours and sparkling jewels. The outstanding graphics and the exciting sound effects create an arcade atmosphere that is engaging and captivating. This is fast-paced, with fun and innovative features. Take for example the Starburst Wilds. These replace the usual wild symbols and expand to cover the entire reel. Plus, these expanding wilds stay in place for up to three re-spins, providing the possibility of astronomical wins.
Another unusual feature is the chance to win both ways. This breaks the mould of traditional video slots and again provides the chance to stack up plenty of payouts. Thanks to the huge popularity of this game, many of the casinos I have reviewed have included it in their game collections. One of my favourite places to play Starburst is 888casino.
Age of the Gods Jackpot Slots
This is not just one game, but a collection of exciting slots with two things in common: Greek mythology and a massive mystery progressive jackpot. There are nearly ten available, each based on different characters and themes within the world of ancient Greece. Highlights include King of Olympus, Furious Four, Goddess of Wisdom and Fate Sisters. There are four jackpots to be won in each, which can be triggered randomly at any time. This means so you don’t even need a winning line in order to enter ant to be guaranteed one of the four jackpot prizes.Age of the Gods Jackpots in Overview
- Power Jackpot – Around £400 every 30 minutes
- Extra Power Jackpot – About £4,000 every 2 hours
- Super Power Jackpot – Up to £35,000 daily
- Ultimate Power Jackpot – Over £800,000
As you can see, the Power Jackpot is the smallest. The biggest payout is the Ultimate Power Jackpot, which is often worth millions of pounds. Along with the draw of these huge jackpot prizes, the games are packed full of interesting features and boast stunning graphics and sound, making for a very enjoyable playing experience. These enticing slots can be found at all Playtech operators, and there’s now also a spin-off roulette game that features the same progressive jackpot pool. My top recommendation for giving these reels a spin is Ladbrokes.
Gonzo’s Quest – With the Innovative Avalanche Feature
NetEnt is famed for its innovative approach to development, and one which captures this style perfectly is Gonzo’s Quest. In it, the traditional spinning reels you find in most video slots are cast aside in favour of the Avalanche feature. This sees the Mayan symbols fall into place in the game. Plus, when a winning combination is lined up, the symbols explode and disappear, allowing others to drop into their place. This creates the opportunity to get multiple line wins from just one “spin”. Also, with every subsequent win, the payout multiplier increases. These exciting features are combined with cutting-edge graphics and 3D animations, that make gameplay enthralling and captivating. Gonzo’s quest is one of the most popular online slots of all time and has been a huge fan favourite since it first became available. You will find it at almost any NetEnt casino.
Game of Thrones – Based on the Much-Loved TV Show
This hugely popular TV series has been turned into an impressive online slot by leading developer Microgaming. There are two versions available, one with 15 paylines, the other with over 243 ways to win. You can play both versions at Betway or at Casumo. The Game of Thrones slot is very true to the TV series, with symbols like the iron throne included, plus video clips and the iconic theme tune playing throughout. Yet it’s not simply the popular theme that has made it a success. It is also packed full of rewarding and exciting features like the bonus round. Here, you take your pick from the four houses of Westeros, each with a different combination of free spins, stacked symbols and win multipliers. Apart from this, there is a gamble trail feature, where you journey through four map locations with the chance to double your winnings at each step.
Fun Real Money Slots with Interesting Themes
The games that I have outlined above are some of the most popular online slots among UK players, but that is by no means an exhaustive list, nor are they necessarily the perfect game for you. All different titles have their own unique features that make them stand out in one way or another, so I’ve highlighted a few real money slots with fun and interesting design elements.
Immortal Romance – a Vampire Romance
Vampires have long been a topic of interest across all different kinds of media, branching from the scenes of books and movies into an online slot with leading developer Microgaming’s much-loved Immortal Romance game. The sultry characters spin on the five-reel, three-row grid that has 243 different paylines and a stack of interesting features. For example, the game’s title card acts as a Wild that doubles any wins it creates, and three or more lion-faces scatters trigger a bonus round. During the so-called ‘Chamber of Spins’, free spins are awarded and wins are multiplied depending on which level of the bonus you are on. The more times you trigger the bonus in during the Chamber of Spins, the higher the benefits. This is one of the most fun real money slots on the UK market, keeping things interesting and sexy all at the same time. You can try a free demo of it here.

Cleopatra – A Timeless Classic in Both Land-Based and Online Slot Casinos
IGT has created some of the most popular and iconic machines found in land-based casinos and also successfully adapted and developed for online play. By far the most famous and outstanding title in this collection is Cleopatra. This Egyptian-themed video slot has stood the test of time: despite the countless new titles that are released online every month with cutting-edge graphics and innovative features, this game has lost none of its appeal with players. It remains one of the best online slots, sought after by players in the UK and beyond thanks to the authentic theme and the expansive range of special features. These include double payouts for wild wins, plus free spins with super-rich reels where winnings are multiplied by three. The game is so much in demand, that two sequels are also available, including a MegaJackpots version with a huge progressive jackpot. What’s not to like? You can play it at Grosvenor online casino.
Gladiator – The Award-Winning Film Becomes a Video Slot
When this iconic Ridley Scott film was released in 2000, it was met with critical acclaim and won a whole host of awards, including an Academy Award for Best Film. The popularity of the film saw it developed by Playtech into an online video slot. The slot was released more than seven years ago but remains a firm favourite with UK players. This is thanks to the superb graphics, intermingled with animations from the film. Additionally, there are plenty of features that make it entertaining and exciting to play. These include not one, but two different bonus rounds. In the Coliseum Bonus round, you take your pick from different squares, to reveal how many free spins you will get and with which multiplier, plus which symbols will become your extra wilds and scatters. There is also a jackpot version of the game available, where the Gladiator Bonus round provides the chance to get your hands on a big progressive jackpot payout. This game is available at most Playtech casinos, but I would recommend playing it at Mansion Casino.
Advantages of Online Slot Sites Compared to Land-Based Casinos and Arcades
There is no doubt that playing online offers numerous advantages compared to playing in a bricks-and-mortar slots casino or an amusement arcade. Some of these benefits are obvious, while you probably haven’t considered some of them. The following section outlines the advantages of playing slots online.
Find A Favourite for Free
Though they always say, “don’t judge a book by its cover”, that’s really all you can do when playing in a land-based casino, which will require money paid first. The majority of online slots, however, can be trialled for free, so you can familiarise yourself with the features of a game before spending any real money. This is especially helpful considering the staggering amount of different titles that are available out there.
Non-Stop Slot Fun With Mobile Casino Apps
Not only are online games available for you to play 24/7, they’re also ready to enjoy from basically anywhere thanks to mobile casino technology. Many operators have their own dedicated app that you can download to your phone or tablet. However increasingly popular is the development of optimised websites that are built using HTML5, which means you can simply open your favourite web browser on your phone and play instantly.
Mobile slots casinos have wide selections of titles, with often hundreds of cutting-edge games with superb graphics and high payout rates. You’ll find an impressive selection of jackpots, including movie- and television-themed franchise slots or others with huge jackpot pools. Whilst not all apps have a sky-high number of options, they offer to have some unique and innovative real money slots from numerous software providers. There are often not as many options on apps or mobile-optimised sites, however, as not all games are coded in an instant-play format. There are, of course, huge arrays of games to play and keep you entertained no matter where you are.
Real Money Slots Bonus Offers
Welcome offers are one of the most interesting ways that an online casino can try to stand out from the clamour that is the UK casino industry. The details of an operator’s welcome bonus can take shape in a lot of different forms, whether it be free spins or extra cash in your account. Some of the best slot site bonuses are highlighted in the table.
- Wagering Conditions: How many times must you wager the amount before it will be credited to your account?
- Claim Deadline: How much time do you have to meet the wagering requirements? This can vary from 24 hours to 90+ days.
- Wagering Contributions: How much do the bets on different gameplay styles count towards the playthrough requirement?
- Restrictions: Are there any types of games or wagers that are excluded from playthrough requirements?
- Betting Limits: Does the operator set any minimum or maximum limits for bets that contribute to the wagering requirements?

The most crucial thing to investigate when looking into any promotion is its terms and conditions, the main points of which are highlighted above. As a slot player, you’ll be pleased to know that you will be treated to some of the most preferential bonus treatment when it comes to the turnover and wagering conditions. Most casino promotions will count wagers on real money slot machines on a one-to-one basis, and giving away free spins is becoming more and more commonplace. Always remember that an online slots bonus is only an offer and one that you can decline if you do not want to deal with the hassle of wagering conditions. If any of the above promotions sound tempting, click through to claim it now.
How to Pay for Your Real Money Slots
Although you can certainly try a lot of different online slots for free, much of the reason we’re drawn to the magic of these games is the potential for a payday. But you have to be in it to win it – meaning you have to put money in the machine for the chance for any to come back out. To do so, you will need to visit the cashier of your chosen operator and choose from one of its many different deposit methods. It is unheard of to find a casino that won’t let you add fund via a credit card, for example, and there will always be at least one type of eWallet like Skrill or Neteller available, too. Also common is the pre-paid, gift card style payment systems such as paysafecard.
Best Slots Casino with PayPal Deposit with the eWallet and start spinning
Another popular alternative for making deposits and withdrawals at online slots sites is through the payment service, PayPal. The main appeal of the system is that once you have created an account, you can quickly, easily and securely make payments to countless websites. You just need to login to the service through the operator, and instantly transfer funds to the casino – this makes PayPal slots extremely popular among players. A rarer option, but still an option nonetheless, is making transactions using bitcoin and other types of cryptocurrency.
How to Tell if Slots are Fairly Programmed
As explained earlier, all games have a return to player (RTP) percentage that dictates how it will pay out winnings over time. But how can we know if these numbers are more than just a figure plucked out of thin air?
Well, as part of the licencing requirements from the UK casino industry’s regulatory body, all titles being offered by operators to British gamblers must ensure their RTP figures are tested and approved by independent bodies. This must happen on a regular basis, too. Many online slots sites will promote this fact by placing the logo for its testing company in the footer of its website, which is why the eCOGRA, GLI and iTechLabs logos may look familiar to you.
1/3 Authority LogosYou will often be able to find the logo of an independently operating testing authority at the bottom of a casino’s website in the footer. Some of the most common companies are shown in this image. Look out for their logos!
2/3 ClickIf the authority’s logo is visible in the casino’s footer, it will usually be clickable. This will take you to either the most recent report from the authority, or the authority’s website. Not all companies publish their reports for the public to see.
3/3 View Report You can now view the accreditation awarded to the operator in questions by the nominated testing agency. This means the games are all certified to be safe and fair. You are free to play!
This is probably one of the biggest advantages of playing slots online. The theoretical payout percentage is usually between 90% and 95%. As for the return to player percentage in brick and mortar casinos, it falls far short in comparison. The reason for this is that online casinos have significantly smaller running costs. In turn, online slot sites are able to pass these savings on to their customers by way of greater payouts. Therefore, if you choose to play online, you are far more likely to see greater payouts than when playing elsewhere.
More Jackpot Games with Bigger Prizes
Online, you’ll find a wide variety of games with progressive jackpots. Each player who chooses to play a jackpot game contributes a portion of the wagers towards a pooled prize fund. Owing to the massive numbers of people that play online slots in the UK, these progressive jackpots can quickly build to staggering amounts.
Much Larger Game Selection
Due to the space restrictions, there is a limited number of slot machines available in a land-based gaming house. When gambling online, this restriction is removed entirely as there are no space limitations, meaning online slots casinos can provide hundreds of different titles. Additionally, online versions allow easy access to game rules and payout tables.
All Games Are Available at All Times
Land-based casinos and amusement arcades do no open 24/7. Plus, there may be restrictions to opening times on some public holidays as well. This issue is eliminated when playing online. Online casino games can be played anytime, day or night, each and every day of the year. Plus, unlimited numbers of players can play the same product at the same time online, so there is no need to fight over the top online slots.
Other Game Styles You’ll Find Alongside Slots
Just like millions of other UK punters, you’re looking predominantly to play slots online. However, the best online slots casinos will also feature other popular styles of games, such as card games blackjack and poker as well as roulette.
Disadvantages of Playing Slots Online
Although I am clearly a convert to the online gambling scene, it would not be a balanced article for you without me also sharing any downsides to playing slots online, as opposed to in a land-based casino. One of the most common complaints centres on the lack of atmosphere when playing at home. For many, heading to the casino is a social affair, where one gets to spend time with friends, play some games, and have a few drinks or a steak dinner. In this case, the night out is just that, more about having a night out. It’s dressing up in your best fancy outfit and enjoying the ambience and company at a gambling house.
Due to the accessibility of playing slots online, some people find that gambling online can have an addictive nature. This is a real problem in the UK, and has prompted the inception of many a responsible gambling firm such as Gamble Aware and GamStop. Many operators also have created their own responsible gambling processes to help look after those who need to watch their gambling habits.
Conclusion: Start Playing Slots Online

Frequently Asked Questions about Slot Games
Did I gloss over a topic too quickly? Is there something more you need to know about the online slot sites in the UK? Feel free to send me a quick email to [email protected] and I’ll respond as soon as possible in the following frequently asked questions section.
Can you win real money in online slot casinos?
Yes, of course, there is real money to be won from slots in online casinos. It is a matter of luck, as the games are all programmed with a random number generator that decides which spins win or lose, but the possibility is always there – as long as you are also wagering with real money funds.
How do you register to play slots at online casinos?
It is very easy to start playing slots at your chosen online casino. All you need to sign up is your name, date of birth, proof of address and identification and an email address. Most casinos streamline their registration processes so that they can be completed in less than five minutes, which is great if you are very impatient like me. Once you have completed the process, you can start to play immediately but you will have to choose a payment method and make a deposit before you can start playing slots for real money.
What is the best online casino to play slots?
Great question. There are lots of different online casinos in the UK where you can play slots, each different from one another, so it is very difficult to pick out the best online slot casino. My list of top operators will, however, give you a selection of the best gambling experiences available for this type of game.
Are online slots legal?
Absolutely. As long as you are playing at a fully-licenced online casino, there are zero issues to think about in terms of legality of slots. You must also follow the casino’s own laws, though: You must be over 18 and a UK resident to legally play at a UK casino.
