The Best Slots to Play Online in 2024

The best slot sites for winning in the UK feature hundreds of online slots. So, how do you choose the best slot games to play online? Some players base their choice on graphics and visual effects.

The Top 10 Best-Rated Online Slots in the UK in Detail

Of course, things can change quite swiftly in the world of online slot games since there are new titles coming out all the time. In the next section, you can see detailed info about the top 10 video slots and what makes them special.

We will constantly update the current 2024 list with the latest online slot games that include random number improvements. So, you might notice some differences! We are dedicated to bringing you slots only from the strongest contenders for the title of the best online casino for UK players.

Gonzo’s Quest

The Gonzo’s Quest Online Slot

Gonzo’s Quest is a hugely popular NetEnt slot with 5 reels, 3 rows, and 20 paylines. Bets range from £0.20 – £50. The stone block symbols cascade into place on each spin. Land a winning combination, and the symbols explode, allowing new ones to fill their place. This Avalanche feature enables you to land consecutive wins with increasing multipliers from 1x – 5x.

I particularly like the Free Fall feature, which gives you 10 free spins. During the free falls, win multipliers build from 3x to 15x, providing the chance to stack up big wins. Our team highly rates this slot, which is why we mention it in many of our UK online casino reviews.

Advantages

  • Avalanche Feature
  • Increasing Multipliers
  • Free Falls Feature
  • 3D Animations
  • 95.97% RTP
  • Mobile-Friendly

Disadvantages

  • No Progressive Jackpot
  • No Bonus Round
  • Fixed Paylines

Mega Moolah

The Mega Moolah Online Slot

Mega Moolah is considered one of the best UK slots to play online. This record-breaking progressive jackpot slot has made several lucky players millionaires. Mega Moolah has 5 reels and 25 paylines. Bets range from £0.01 – £6.25, making a great choice for beginners and low stakes players. The game features free spins where all wins are tripled. It also has a multiplier wild which doubles the payout.

Like the rest of the team, I enjoy playing the Mega Moolah slot. While the chances of hitting the jackpot are slim, you cannot beat the thrill of knowing that any spin could randomly trigger the jackpot game. Given the popularity of this game, it is available at many of the best slot sites in the UK.

Advantages

  • Progressive Jackpot
  • Free Spins with 3x Multiplier
  • Multiplier Wild
  • Fun Animal Theme
  • Adjustable Paylines
  • Available for iOS & Android

Disadvantages

  • High Stake Bets Unavailable
  • Jackpot Rarely Triggered
  • Low RTP

Starburst

The Starburst Online Slot

Starburst is an iconic NetEnt slot available at the best slot websites. It has the feel of an arcade game, with slick graphics, blasts of light, and electrifying sounds. Starburst is a 5-reel slot with 3 reels and 10 paylines which pay both ways. You can play this game with bets of £0.10 – £100. Expanding Starburst Wilds are the game’s key feature. When a wild lands, it expands to fill the entire reel and locks in place for a re-spin.

Starburst lacks free spins, bonus rounds, and other typical slot features. Yet, this is what I love about the game, and the rest of the team agrees. It features simple yet high-paced and energising gameplay that immerses you into the game. It was released in 2012 and remains among the best online slots to play in 2024.

Advantages

  • Low Volatility
  • Win Both Ways
  • Expanding Starburst Wilds
  • Arcade-Style Gameplay
  • Immersive Sound Effects
  • Win up to 50,000 Coins

Disadvantages

  • No Free Spins
  • No Bonus Game
  • No Win Multipliers

Goblin’s Cave

The Goblin's Cave Online Slot

Goblin’s Cave is an innovative Playtech slot. It is a 3×3 slot with stakes ranging from £0.03 – £150. When you click spin, the bottom reel fills with symbols. You can hold any of these symbols before spinning again. This hold feature adds an element of skill to the game, which is reflected in the RTP. When you play with max coins and optimum strategy, the RTP reaches a massive 99.32%.

This is one of the most unique online slot games I have seen in the UK. If you want a change from classic gameplay, I highly recommend giving Goblin’s Cave a try. Our team found the element of decision making made the game engaging and provided a unique gaming experience unlike other online slots.

Advantages

  • High RTP – Up to 99.32%
  • Pick and Win Bonus Game
  • Hold Symbol Feature
  • Wide Betting Range
  • Element of Skill Involved
  • Innovative Gameplay

Disadvantages

  • Dated Graphics
  • No Free Spins
  • Not Available for Mobile

Game of Thrones

The Game of Thrones Online Slot

The Game of Thrones TV show may be done and dusted, but you can still get your fill with the Game of Thrones online slot. The 5×3 slot authentically captures the TV show theme with its symbols, music, and features. This slot is available with 15 paylines or 243 ways to win. The slot includes stacked wilds and a gamble feature. It also has a free spins selection, where you choose from four features with differing combinations of free spins and multipliers.

As a Game of Thrones fan, this is one of my favourite UK online slots. However, our team is a mixed bag. Not everyone liked the show, and therefore, not everyone enjoyed the game as much. Still, we all agreed that GOT enthusiasts will love this game.

Advantages

  • TV Show Theme
  • Pick and Win Bonus Game
  • Free Spins Selection
  • Stacked Wilds
  • Gamble Feature
  • Choice of 15 or 243 Ways to Win

Disadvantages

  • No Bonus Game
  • No Progressive Jackpot
  • Niche Theme

Avalon II

The Avalon II Online Slot

Avalon II is a medieval-themed Microgaming slot focusing on the legend of King Arthur and the Knights of the round table. The slot has 5 reels, 3 rows, and 243 ways to win. The bet size ranges from £0.30 – £30. This game’s highlight is the Holy Grail bonus. It is an 8-level bonus round. Among the bonus games, you will encounter trailing wilds, free spins, multipliers, and cash prizes.

This slot is a sequel to the popular Avalon slot, and it brings a lot more to the table. I was impressed with the sheer variety of special features that are offered in the Holy Grail bonus. The bonus features include player favourites, like free spins, alongside unique mini games our reviewers have not seen in other slots.

Advantages

  • Player-Favourite Theme
  • Multi-Level Bonus Round
  • Win Multipliers
  • Free Spins
  • Trailing Wilds
  • Mobile Compatible

Disadvantages

  • No Gamble Feature
  • No Jackpot
  • Fixed Paylines

Cleopatra

The Cleopatra Online Slot

The Cleopatra slot by IGT is a popular land-based casino game that is also available at the top slot sites for UK players. The 5-reel Ancient Egypt-themed slot has an adjustable 20 paylines. You can play with bets of £0.01 – £200. Cleopatra is the wild symbol, which doubles the payout when completing a winning symbol combination. The slot also features a free spins bonus with wins multiplied x3.

While there is no shortage of new slot games you can play online, players return to Cleopatra time and again. It is a timeless classic that is just as popular online as at land-based casinos and arcades. It rightly deserves its place on our best UK online slots list.

Advantages

  • Popular Egyptian Theme
  • Good Betting Range
  • Wild Wins Pay x2
  • Free Spins with 3x Multiplier
  • Mobile-Friendly
  • Scatter Pays

Disadvantages

  • Dated Graphics

Da Vinci Diamonds

The Da Vinci Diamonds Online Slot

Da Vinci Diamonds is another IGT slot popular in both land-based casinos and online slot casinos. Inspired by Leonardo Da Vinci’s artwork, you will see the painter’s renowned portraits featured among the symbols. This slot has 5 reels and 20 paylines, with bets of £0.20 – £200. The game uses Tumbling Reels mechanics, where symbols fall into place, allowing consecutive wins from a single spin.

The Da Vinci Diamonds free spins bonus is my favourite game feature. You play the free spins on a new set of richer reels, including bonus scatter pay symbols. Our team conducts many slot reviews, and we all agree that Da Vinci Diamonds may be old, but it is still in style.

Advantages

  • Tumbling Reels
  • Free Spins with Richer Reels
  • Bonus Scatter Pays
  • Unusual Theme
  • Mobile Compatible
  • Wild Substitutions

Disadvantages

  • No Gamble Feature
  • No Win Multipliers
  • No Jackpot

Dead or Alive

The Dead or Alive Online Slot

Dead or Alive is a hit video slot with a Wild West theme. The 3×5 slot has just 9 paylines, with a low bet range of £0.09 – £18. The game has a high RTP of 96.82%. Dead or Alive boasts a free spins feature, where you get 12 free spins with payouts multiplied x2. During the free spins, sticky wilds can land on the reels. They activate an extra 5 free spins and stick in place for the duration of the bonus.

Dead or Alive is one of NetEnt’s high volatility slots. During the free spins, the sticky wilds give you the chance to pocket big wins of up to 3000x your stake on every free spin. The mobile-friendly game is available on Android, iOS, and Windows devices.

Advantages

The DOND online slot has 3 bonus features, including free spins with double wins, the Banker’s Best Offer bonus, and the progressive jackpot bonus, where you can win one of three big money prizes.

This slot game authentically captures the thrilling gameplay of the TV game show. The bonus features are exciting and offer the chance to pocket decent rewards. Plus, its wide-reaching betting limits make it accessible to all players. It is a winner all round.

  • Multiplier Wilds
  • Play on Mobile

Disadvantages

What Are The Best Progressive Jackpot Slots?

When we rate the best online slots, we pay special attention to progressive jackpot slots. Progressive slots are much-loved by online slot players, and you will find them at all the best slot sites in the UK. But the huge jackpot prizes have a cost – the base games usually give out worse payouts than their counterparts.

Any jackpot game aims at attracting customers with lucrative rewards. They are programmed so because a portion of every wager goes to the huge jackpot pot. That’s why progressive jackpot games are the best slots to play if you want the chance to win big money. So, we have to use different criteria when we try to rank the best jackpot slots. You can see the current top 3 list for 2024 down below!

Mega Moolah by Microgaming

🎰 Largest Paid Jackpot £16.8 million
⏱️ Average Period around 122 days
💰 Average Payout £2.1 million
💸 Average Increase £12,300/day
🏆 Recommended Casino Karamba

The main attraction of this game is the progressive jackpot. Slot bonuses during the game can improve your user experience a lot. When the bonus game is randomly triggered, you have the chance to spin the wheel without any wagering requirement, which holds the four different jackpot prizes.

The most appealing of these prizes are the major jackpot, which starts at £10,000, and the mega jackpot, which is guaranteed to be at least £1million. The mega jackpot regularly builds to several million pounds. Jackpot payouts always provoke big interest among players.

Mega Fortune by NetEnt

🎰 Largest Paid Jackpot £15,143,600
⏱️ Average Period around 70 days
💰 Average Payout €4.2 million
💸 Average Increase 60,000€/day
🏆 Recommended Casino Grosvenor

The Mega Fortune Slot by NetEnt has held the Guinness World Record for the biggest progressive jackpots ever paid among the jackpot games. We can consider this game the jackpot giant on the market and one of the best online casino slots for big payouts.

This is not the first time this slot is in the spotlight, as it was the holder of the last slot payout record, with another impressive win: 11.8 million euros. By the average daily increase of 60,000€, I think it is safe to say that this is one of the most popular online slots in the UK.

Beach Life by Playtech

🎰 Biggest Jackpot £5,416,245
⏱️ Average Period around 165 days
💰 Average Payout $2.25 million
💸 Average Increase $13,600/day
🏆 Recommended Casino Mr Vegas

Beach Life is the record holder among Playtech slots.

The happy slots player took home a staggering 8 million dollars. Beach Life is by far the largest progressive slots offered by Playtech at Mr Vegas Casino. Of course, the probability of winning this jackpot is lower than on other slots, but you can also try some of the Age of Gods Slots with huge progressive jackpots.

The Best Mobile Slots of 2024

The best online gambling sites in the UK offer the option to play slots on your phone. So, you can play online slot machines and other new games wherever and whenever you like. Playing on the go could improve your overall gaming experience. Software developers invest significantly in optimising their games for mobile play. So, the top slot games should be fully compatible with mobile casinos.

Mobile slots feature the same payout percentages and volatility as their desktop versions. Below, we have listed the top-rated online slots to play on mobile devices. We have also included the best casino apps to play these top slots on the go.

Slot for Mobile Compatibility Slot Software Best Casino Secure Link
Cleopatra IGT iOS, Android NetBet Play on Mobile
Gonzo’s Quest NetEnt iOS, Android Karamba Play on Mobile
Game of Thrones Microgaming iOS, Android Betvictor Play on Mobile

Jack and the Beanstalk NetEnt iOS, Android The Grand Ivy Play on Mobile

Download or Instant Play? It All Depends On Your Internet Connection

Perhaps you are unsure whether to play a slot game on a casino’s download platform or directly in the browser. In that case, the main factor to consider is your internet connection.

There are few differences between the two playing modes. Games will load slightly quicker if you download and install the casino software. Still, many players find it more convenient to play slots online instantly in the browser. If you have a slow internet connection, we recommend using the download version to play the best online slots in the UK.

Use the download version if your connection is under 1 Mbit/s
For connections over 1 Mbit/s, instant play games load relatively quickly
For mobile devices use native apps and a WiFi connection

If you want to play slots on a mobile device, we recommend connecting to WiFi and using a native app. Keep in mind that the connection from your mobile internet provider may be slower or even limited. Unfortunately, not all operators offer Android, iPhone, and iPad download apps. Still, all the best slot sites in the UK offer web apps compatible with most devices.

The Best Payout Percentage in Online Slots for the UK

An online slot game’s RTP shows the potential payouts the game will award. So, theoretically, slots with a high RTP are the best online slot games to win money. As most players want to improve their winning odds, many seek the best RTP online slots. However, the theoretical payout percentage alone does not give you enough information. You should also consider other factors, such as the game’s variance (or volatility).

The slot variance tells you about the size and frequency of payouts. Slots with low variance will earn you frequent but small wins. In contrast, slots with high variance can award big wins, but only occasionally. So, you need to check various details if you want to play the online slots with the highest payouts. To help you out, we have prepared a list of the best paying online slots in the UK:

Top Slots Payout Percentage Slot Volatility Secure Casino Link
97.00 Low NetBet
96.13 Low Mr Vegas
96.80 Medium Betvictor
96.80 High 888casino
96.30 Medium Karamba

1 Pick the Best Slots
Some of the main criteria when choosing an online slot game can be: RTP, volatility, jackpots, bonus rounds, bet range, max win, graphics, software or features such as autoplay.

The main features of safe slot sites include: a valid license from the UK Gambling Commission, certified payout audits from independent organisations such as eCogra, secure payments and data protection.
3 Check the Slot RTP
The Return to Player Rate of online slots represents the long-term payout percentage from all placed bets. Higher RTP indicates better odds of winning – however, you should consider other factors such as variance.

Most UK online slot players prefer to boost their betting balance with a casino bonus. You should always check the wagering terms before opting in for a bonus deal – claim only bonuses with 100% slot game weight.
5 Try the Mobile Slots
Most of the new online slot games are fully optimised for mobile play on both Android and iPhone. Playing on the go is a must nowadays, so you should make sure that your chosen platform offers a good mobile experience.

When you have finished your selection, you should create your account at the chosen UK slot site. You will need to verify your identity to guarantee the safety of your money. When making your first deposit, choose a payment tool which you can use for withdrawals later on.

Online Slot Machine Basics & Important Terms

Online slots are easy to play. Still, there are some basics you should know before you start playing real money online slots. You should familiarise yourself with game configurations, including rows, reels and paylines. You should know the different types of symbols and how they create winning combinations. It is also advisable to know about RTP and variance, which tell you about how a slot’s payout behaviour. Below, we delve into the important slot terms in more detail.

  • Reels

    You will encounter slots with varying numbers of reels when playing online. The most common type of online slots are video slots. These games usually have 5 reels, although, some games could have 6, 7 or even more reels. You could also come across classic online slots. A traditional classic slot game will have just 3 reels.

  • Rows

    When you play video slots online, you will find most games have 3 rows. Still, some video slots have 4 rows, and some have even more innovative set ups. For example, Megaways slots have expandable rows and can go from 2 to 7 during the game. You will find classic fruit machines have either 3 rows or a single row across the 3 reels.

  • Bet

    Most online slot games available in the UK have adjustable bet sizes. You can adjust the bet per line, the bet level, and sometimes the number of bet lines can be adjusted. All these factors combined will determine the bet per spin. Most slots have a minimum bet of 1p per payline. The maximum bet varies between games. You can use the max bet button to play with the largest possible stake.

  • Symbols

    Online slots have various symbols that payout when you land a matching symbol combination on a payline. Yet, there are also some special symbols to be aware of. Many games feature a wild. A wild symbol will substitute for another symbol to create a winning combination. In some games, wilds can be multiplier symbols, which could double or triple a payout when completing a winning combination.

    Sticky symbols are a type of bonus feature that lock onto the reels when they land and stay in place for further spins. Sticky wilds are a popular feature in free spins bonus rounds. Stacked symbols are a sequence of identical symbols that are stacked onto the reels. This boosts the chances of them becoming part of a payline. Colossal symbols are larger than standard symbols and cover more positions on the reels.

    Many slots include scatter symbols. These symbols do not need to appear consecutively on a payline to award a win. Instead, usually landing 3 or more scatters anywhere on the reels will payout a multiplier of your total bet. Scatters often trigger bonus games and free spins features. In some of the best UK online slots, such as Big Boss Bonanza, the scatters only trigger a feature and do not also provide a payout.

  • Winning Combinations

    Online slots commonly pay out from left to right. If you land a certain number of matching symbols consecutively from the first reel on an active payline, you will receive a payout according to the paytable. The more symbols you land, the higher the payout. Some games pay out from right to left. Others, such as Starburst, pay both ways. Some games, such as 243 ways to win slots, payout for matching symbols in any position on consecutive reels.

  • Return to Player

    The Return to Player (RTP) percentage expresses the portion of all wagers on a slot game that are paid back to players as winnings. For example, the Rainbow Riches slot has a 95% RTP, meaning it pays out £95 of every £100 wagered over the long run. You will also hear house edge mentioned. This refers to the portion of wagers that the casino keeps as profit. Many players seek the best RTP casino slots as they pay out more overall.

  • Variance

    Variance, also referred to as volatility, tells you about a slot’s payout behaviour. Low volatility games pay wins frequently, yet the payouts are small. High volatility slots, on the other hand, pay out infrequently. However, when the wins land, they tend to be big in size. Medium variance slots fall between low and high variance online slots.

Modern Online Slot Features

Game developers are constantly pushing the boundaries when creating online slots. They create ever more innovative features, giving players exciting new options to try at the best online slot casinos. Some of the latest online slot innovations include Megaways, Megapays, and slots with nudges. Find out more about these new slot features below:

  • Megaways Slots

    Megaways slots were originally developed by Big Time Gaming. They feature an innovative random reel modifier. The number of symbols that appear on each spin varies, creating differing numbers of paylines. These slots have 6 reels and between 2 and 7 rows and can offer up to 117,649 ways to win. Fluffy Favourites Megaways by Eyecon and Dynamite Riches Megaways by Red Tiger Gaming are some of the best Megaways slots to play at an online slot casino.

  • Megapays Slots

    Megapays slots are similar to Megaways online slots. However, they have one significant difference. Megapays slots feature a 4-tier progressive jackpot. These slots feature the innovative and exciting Megaways gameplay mechanics. Yet, they provide extra thrilling gameplay, as any spin could trigger the jackpot. The jackpot game takes place on a new set of reels, where you can climb the jackpot meter to scoop the Mini, Midi, Major, Mega jackpot. You can play Megapays slots at the recommended slot sites.

  • Slots with Nudges

    Nudges are a typical feature of old-school fruit machines. Yet, they have become one of the latest trends in online slots. The nudge feature allows you to move a reel after a spin, giving you an extra chance to line up a winning symbol combination. Some nudge slots also include a hold feature, where you can lock certain symbols in place while nudging. Some popular online slots with nudges include Blaze of Ra and Big Boss Splash.

How to Win on Slots: Tips for Real Money Play

If you feel that you are ready to try one of the best casinos to play slots, then you should still prepare yourself – you will be wagering real money at the best online slot websites after all! Here are three important tips for real money slot game play at the best slot sites:

  1. The strategy of progressive betting

    A popular system for playing online slots at the best online slot site is to start with the lowest bet and increase it every 50 spins. If no free games or big wins are awarded during these spins, it is time to raise the bet per payline. This way, when you hit something on a higher bet, it will be more than enough to compensate for your investment. However, given the high variance of some slot machine games, this strategy has its drawbacks, as it could be a while before you hit a big win.

  2. Play on slots with the highest payout percentage

    Few players acknowledge the importance of the RTP when playing slots. However, it determines how much of your investment will be returned to you under ideal circumstances. Online slots (and some classic slots) usually have an RTP of over 90%, but only some of the best slot payouts will reach more than 95%.

    It is also important to remember that the RTP is slightly lower for progressive slots. The lower payout rate is because part of the money you wager goes into the jackpot. And given as jackpots are different sizes and different percentages of them can be won, the expected profit may vary. You can also check for some free slots to practice first and make a better strategy in advance. If you play free online slots, it could help you find the best slots to play online with real money.

  3. Play only for the highest jackpots

    A good piece of advice for online slot game players is to play only the highest jackpot slots. Of course, the bigger the jackpot, the bigger the win, but that is not the only reason. A small prize means that someone has already hit this jackpot recently, which is not likely to happen again too soon.

    A huge jackpot, on the other hand, means that the winnings are piling up and there is a bigger chance of you winning it. It is almost impossible to calculate the exact probability of you hitting the jackpot, but the bigger it is, the bigger the profit expectancy becomes. A free slot game can offer you the chance to examine carefully the gameplay features. In the following paragraphs, I will give you facts on some of the biggest wins on famous slots, as well as average periods and payouts.

The Best Online Slots Bonuses in the UK

Just about all operators offer bonuses to attract new players. Such welcome bonus offers are great news for players, as they give you extra playing time and more chances to win. Still, some offers provide a better deal than others. We have compared slot bonuses and below, you can find the best slots bonus for UK slot players:

Why You Should Deposit Using PayPal and Moneybookers When Playing Online Slots

When you decide to start playing slots online at UK sites, safety should always be your priority when you enter the online slot sites. The safety of your personal and banking details and passwords should always be in good hands, as all information that is transmitted over the Internet can, at one point, be intercepted. You should also be able to choose convenient deposit limits.

This is why when you play slots online, we recommend using PayPal and Moneybookers (Skrill) instead of a debit card to manage your funds at online casinos, as such data doesn’t get divulged or transmitted to the respective casino operator. Besides, those banking options come with no withdrawal restrictions at every good slot site. This makes them perfect for playing the top online slots at the best fast withdrawal casino in the UK.

Of course, sensitive data needs to be transmitted that cannot be avoided. However, with these electronic wallets, the information remains in the safe hands of organisations with huge experience in the field. Of the two payment methods, most casino players prefer PayPal.

This is simply the biggest e-wallet out there, and most people tend to rely on it for their online transactions – if a slot site is partnered with it, this is also considered a positive sign about its reliability. However, not all operators use the services of a payment method such as PayPal. You can check the best PayPal casinos in the UK to find those that do. We also keep a running list of PayPal slots that you can enjoy with a quick and safe deposit.

Other Payment Methods to Play Slots Online with Real Money

PayPal and Moneybookers/Skrill may be the most popular methods for depositing at an online slot site, but they are by no means the only methods you can use. The best slot sites for UK players accept a variety of secure payment methods. Among which are other e-wallets, prepaid cards, debit cards, and mobile payment methods. All UK online casinos support at least a few of the following services:

When choosing which payment method to use at UK online slot sites, you should remember that not all options support withdrawals. This is often the case with prepaid cards and mobile payment services. It is also worth noting that deposit limits can vary between payment methods. Some options offer enhanced security and privacy. Still, when you play at licensed UK slot sites, all deposits are processed securely.

In comparison, Playtech shines with a rich selection of branded slots and jackpot slots, like Sahara Riches Cash Collect.

The software developers listed above are safe and certified. Their games are independently tested and give you a fair chance of winning.

Advantages and Disadvantages of Online Slots Compared to Other Casino Games

Advantages
  • Dynamic gameplay
  • Higher payouts
  • Huge jackpots
  • No skills needed
  • 100% Bonus contribution
  • Great variety of games
Disadvantages
  • Higher potential addiction
  • Not engaging, only spin needed
  • No live game version

In terms of gameplay, there could not be any easier and less engaging game than slots. Slots offer amusing features. The only thing you need to do before you start playing is to set the number of max lines to play and the bet per line. Then all you have to do is press the ‘Spin’ button or choose the ‘Autoplay’ option for up to 100 pay lines or until feature.

Some table games like roulette can also be considered a fairly simple game, but Video Poker or Blackjack require more strategic thinking to choose the course of the game, which can make the difference between a win and a loss. The indisputable advantage of playing online slots is the opportunity of hitting a huge jackpot, which can even reach millions, as opposed to the classic casino games like blackjack or roulette.

While playing slots, the entertainment is guaranteed not by challenging gameplay and strategic thinking but through great graphics and sound effects. Also, video slots often include great animations, videos and interesting bonus rounds common across many real money slots. Some even offer exclusive customer support. You can find lots of new and innovative online reels at new online casinos, who often team up with newbie software developer companies. These developers typically have their finger on the pulse of the online gambling industry and create cutting-edge slot products with excellent graphics, storytelling and features.

Slots, however, also have few drawbacks when compared to classic casino games. There are few live versions of this game. Also, the potential addiction is higher with slots than the other best games. So, once you have chosen the best slot site to suit you, make sure you set yourself limits and play responsibly. After all, responsible gambling is the best way to make playing slots safe and fun. Every reputable online casino will provide tools to help you play repsonsibly.

Another possible drawback to slots is that they are not always suitable for high rollers, as the limits are not usually as high as the ones on table games. If you are looking to bet a lot of money on a game, you should search through the top high stakes casinos in the UK to find your next destination. Low rollers can enjoy some of the best penny slot machines to play at all of our whitelisted casinos.

Casino Player Questions About Slots

Here we will answer the most common questions that casino players have when it comes to online slots.

*️⃣ What is the best online casino to play slots?

'Best' is a subjective term, especially when considering how quickly things change on the internet. For fans of online slots, there are many factors to keep track of, like the slot bonus, the game catalogue, the mobile performance, the payment policy and the biggest jackpots. Of course, we keep our list of the best slot casinos constantly updated.

*️⃣ Which online slots are the best?

Different players consider different factors, but most commonly you need to keep track of the RTP rate and the slot volatility. Most players also have a preferred software studio – and never forget the casino bonus, which is usually perfect for slot play. We consider this and much more when we pick our top 5 slots to play online.

*️⃣ Which online slot machines pay the best?

Players often hunt for loose slots. Another favoured superstition is the hot and cold slots myth. RNG modules make such tactics obsolete. When we filter the best paying online slots in the UK, we consider the data verified by the UK Gambling Commission. We also run tests in demo and for real at the best online real money casinos.

*️⃣ How do you pick a winning slot machine?

You don't. There are never any guarantees that you will find a slot machine that is sure to win. However, you can improve your odds by playing smart. Check all the available data, and take the time to pick just the right slot. You can refer to our slot tips and tricks for more information.

*️⃣ Can you make money playing online slots?

It comes down to luck, but the chance to win is guaranteed – if you play at a safe casino. If the online casino has valid licences from the UKGC, then slot games are guaranteed to give winnings.

*️⃣ Which gambling games are the most popular?

Slots are the most popular casino games in the UK and worldwide. The statistics for 2024 show an overwhelming advantage of slots compared to all other casino games. Of course, this doesn't automatically make slots the best online casino games – they have their own advantages and disadvantages when compared to other popular casino games.

*️⃣ What slots have the best odds of winning?

Easy - slots with the highest RTP. Return to player rate (payout percentage) shows what winnings a game will give in the long run. The higher the RTP, the higher the odds of payouts. Slot players are more interested in the odds of hitting a top prize. Those are harder to determine since online slots run on complex RNG software.

*️⃣ Are online slots rigged?

Online slots developed by certified software providers cannot be rigged. They are subject to regular audits by third-party testing agencies. The same goes for slots that are featured at a certified online casino. So, to stay safe, stay with licensed casinos and established slot developers like Microgaming, NetEnt, Playtech and IGT, so you have a guarantee the slot isn't rigged.

*️⃣ Which are the best online slot machines of all time?
