In this guide we cover everything you need to know about UK online slots – from the best slots sites and the variety of slots on offer to how to play online slots and much, much more.

Online slots are undoubtedly one of, if not the most, popular casino games amongst UK players. The sheer number of unique games and the huge range of themes, designs, and gameplay features are unrivalled in any other genre of casino game.

No two slots are ever exactly the same – there are thousands of games offering a unique gaming experience, meaning that slots fans always have something new to play.

UK Online Slots

How We Choose The Top Online Slots 

Finding the best games to recommend to our readers can be tricky, which is why we employ a team of veritable casino experts with years of experience in the industry to pick out the very best UK slot games using a pre-approved list of features.

Here’s how we ensure that we find the best online slots UK for you to enjoy:

    User Interface

    Themes and Graphics

    We look for games that have cutting-edge graphics and well-designed themes, giving you a top-class visual experience.

      RTP

      Payout Rate (RTP)

      Slots that have higher RTP rates payout more often, making them more appealing to the average player. That’s why our experts look for the best payout slots with high RTP rates, giving you a better chance of receiving a payout.

      Deposit Match Bonus

      Volatility

      As well as RTP rates, we also check the volatility of a slot to see how often it pays out; high volatility slots pay out larger amounts less frequently, whereas low volatility slots pay out lower amounts more frequently.

        Bonus Features

        Features

        Games that offer a diverse range of features, such as Wild symbols, free spins, and bonus rounds, are much more likely to make our list of recommendations.

          Responsible Gaming Measures

          Bet Limits

          We know that the bankrolls of our readers come in all shapes and sizes; to help everyone enjoy our recommendations, we look for slots with low minimum and high maximum bet limits.

            Casino Bonuses

            Bonuses and Promotions

            When claiming an online casino bonus, you want to know that you’re going to be able to use it on the best games. Our experts check the T&Cs of casino bonus offers to determine which slots can be played with your bonus funds.

              Mobile App

              Mobile Compatibility

              With mobile gaming becoming increasingly popular, it’s important that an online slot can be played on both Android and iOS devices. Our team tests each slot on multiple mobile devices to ensure full compatibility.

              Like

              Demo Versions (Free Play)

              Not everyone wants to play online slots for real money, so it’s important that a game offers a demo version that allows players to enjoy the game without risking any of their hard-earned cash.

              Secure Socket Layer

              Software Provider

              When evaluating an online slot, naturally we take a look at the software provider behind it. Games that come from recognised software developers with a reputation for creating quality games are more likely to be good enough quality to make our list of recommendations.

              Slots to Avoid

              Due to the large number of slot games available at real money casinos, it’s only natural that there are a few duds out there that you should avoid. Look out for slots with a combination of these features.

              • Low RTP - Slot games with a low RTP rate without accompanying features like large jackpots should be avoided as they do not pay out as frequently as other slots. Games with an RTP rate below 85% fall into this category. 
              • Low Maximum Win - Games that have a low maximum win offer little incentive for you to play them. There are hundreds of games with huge potential winnings on offer, so don’t waste your time on low-win games. 
              • Basic Design - Online slots have developed rapidly in the last twenty years, so there is no excuse for a game to have poor graphics or a basic design.
              • Unlicensed Developer - If the game is made by a developer without a gaming licence, there is a risk that the game can be manipulated, causing increased losses. 

                The Pros and Cons of Online Slot Games

                Like with any game, Online slots have their pros and cons. Here are the perks and drawbacks of playing online slots UK.

                Pros
                Cons
                • You can claim bonus offers and enjoy more funds to bet on slot games.
                • You can play online slot games for free, which is not possible at land-based casinos. The free play offers the same experience, but you are betting with free credits.
                • Online casinos have a much more diverse range of slot games, so you’ll be spoilt for choice.
                • The slots online are built in mobile-friendly technology so you can take all the action on the move.
                • At online casinos, getting your winnings is not instant, unlike playing at a real brick-and-mortar casino.
                • Playing slots online doesn’t offer any social interaction.
                • Getting money in and out of your online casino account to play slots can mean additional charges.

                Here are the most popular varieties of online slot games you can expect to find at the average online casino.

                  Classic Slots

                  Classic slots, often called three-reel slots, are inspired by the original mechanical slot machines. These games have three reels with basic symbols such as bars, fruit, bells, and sevens. You’ll find that these games offer a lower number of paylines than modern slots and don’t have as many bonus features, leading to a more simplified gaming experience.

                  Progressive Slots

                  If you’re a fan of huge prizes, then progressive jackpot slots are the game for you. These online slots offer jackpots that increase incrementally, with a small part of each player’s wager contributing to the prize pool. Typically, there are four jackpots a player can win; Mini, Minor, Major, and Grand. Some progressive slots jackpots rise into the millions of pounds. These games typically use a 5x3 reel structure and offer features such as bonus rounds, Wild symbols, and free spins.

                  3D Slots

                  3D slot games are built around their ability to offer enhanced graphics. They use 3D graphics, animations, and symbols to create an immersive playing experience that can’t be matched by basic 2D slots. The reel structure, themes, and gameplay features will vary from game to game, but you’ll always get cutting-edge 3D graphics.

                  Fruit Machines

                  Fruit machines are a sub-category of the classic slot games and are one of the most popular slots of that variety. The symbols are almost always fruit themed. These games are reminiscent of the old one-armed bandits that you would see in the olden days, using a 3x3 reel structure and a limited number of paylines, relying mostly on nostalgia to attract an audience.

                  UK Fruit Machines

                  Megaways Slots

                  Megaways slots offer a unique payout structure with a variable number of symbols on each reel. The number of available paylines will vary depending on where the reels land, maxing out at a staggering 117,649 giving you plenty of opportunities to find a winning match.

                  UK Megaways Slots

                  Mobile Slots

                  While many online slots can be played on mobile devices, mobile slots are specifically optimised for mobile gaming. These slots offer increased performance, better graphics, intuitive controls, and touchscreen functionality, allowing you to game on the go without hindrance.

                  UK Mobile Slots

                  Multi-Payline Slots

                  Multi-payline slots have multiple paylines that allow you to win multiple times in one spin. While these games may offer increased chances of winning, they come with an increased risk, as you must make larger bets to cover all of the available paylines. Many of these games will allow you to choose how many bet lines you’d like to play, giving you full control over the amount you bet.

                  UK Multi Payline Slots

                  Interactive Slots

                  Interactive slots offer a more engaging gameplay experience thanks to the mini-games and bonus rounds they offer. These mini-games require player participation, either through skill-based games or decision-based games, giving players influence over their results.

                  UK Interactive Slots

                  Video Slots

                  Video slots create an enhanced visual experience for the player by emphasizing design and offer a diverse range of themes, with some slots recreating your favourite movies and TV shows and others drawing inspiration from ancient civilisations. These games offer state-of-the-art animation and complex symbol designs, as well as improved sound effects that match the tone of the slot. These games typically have five reels, creating the opportunity for hundreds of potential paylines, as well as features such as Wild symbols, Scatter symbols, and bonus rounds.

                  UK Video Slots

                  VR Slots

                  VR slots or virtual reality slots are a modern variation of the traditional online slot that utilises virtual reality technology to offer players a truly immersive playing experience. When playing these games with a VR headset, you are transported to an entirely different world, giving you an unmatched gaming experience.

                  10 Quick Strategy Tips Before You Play UK Slots

                  As online slots are all about luck, there is no tried and tested strategy to implement. However, there are a few things you can do to get the most out of your gambling experience. 

                  1. Check the pay table: All online slot games have a pay table available to view. This is unique to every game and displays what each symbol is worth and what you need to create wins.
                  2. Check banking options: Check out the different banking options to make sure that the casino has payment services you are familiar with. The best casinos will accept a choice of bank cards, eWallets, prepaid vouchers, and more. 
                  3. Look for high RTPs: The RTP (return to player) percentage varies, and anything over the industry average of 96.5% will give you a better chance of cashing out a profit.
                  4. Find the best bonus rounds: Some best slot games are jam-packed with rewarding bonus features. Once you have triggered a bonus round, you are almost sure to hit decent wins. Try and find games with lucrative bonus rounds.
                  5. Play the classics: The traditional slot games often have a higher payout percentage. There is a reason why these games are still super popular amongst slot enthusiasts!
                  6. Hit up smaller jackpots: Playing games with regular jackpots over progressive jackpots will offer a better chance to land bigger wins.
                  7. budget control: You should set a budget and stick to it. You should also consider increasing the bet limit if your budget allows. The bigger the bet, the bigger the win.
                  8. Do your research: There are plenty of sites that offer in-depth information on online slot games. Some slot games have legions of fans because of the win potential and gameplay.
                  9. Avoid the gamble feature: Many slot games have a gamble game where you can risk your winnings for a double-or-nothing bet. It’s always best to avoid this feature.
                  10. Play smart: You should only gamble and play slots when you’re in the right frame of mind. You should avoid playing when on alcohol or feeling stressed.

                  The game can even be played on mobile devices, allowing you to have fun while on the move. The game offers a variety of features, including expanding symbols, bothways payouts, sticky Wilds, respins, and many more!

                  Book of Dead Slot Game

                  Developed by Play’n Go in 2016, Book of Dead is loosely based on the Book of Ra slot machine; arguably one of the best physical slot machines ever created. The game has a 94.25% RTP rate and a high volatility level but makes up for it with a 5,000x max win. The bet ranges start from as little as £0.01 and rise up to £100, allowing players of all bankroll sizes to enjoy this game.

                  The game uses a traditional 5x3 reel layout with a total of 10 paylines. Book of Dead is available to play on both PC and mobile devices and boasts a variety of features, including free spins, expanding symbols, and Wild symbols.

                  While the design is fantastic and we love the 5,000x maximum win, we’d like to see more paylines and a slightly higher RTP rate.

                  Online Slots UK Bonuses and Promotions

                  When playing slots for real money at UK online casinos, you get to take advantage of the various bonuses and promotions on offer! These casino bonuses can offer great value for money and allow your deposit to last longer. 

                  Let’s take a look at some of the casino bonus offers you can use to enjoy your favourite online slots.

                    welcome-bonus

                    Welcome Bonus

                    Almost all UK casinos offer a welcome bonus to attract new players. The most common form of the welcome bonus is a matched deposit bonus that matches a percentage of your deposit with bonus funds. For example, if you claimed a 50% matched deposit bonus with a £100 deposit, you’d receive an extra £50 in bonus funds that you could use to play online slots.

                    Responsible Gaming

                    No Deposit Bonus

                    A no deposit bonus is an online casino bonus that provides rewards such as bonus funds and free spins without having to make a deposit. Typically, a no deposit bonus requires you to create and verify a new casino account, upon which your rewards will be automatically added to your account.

                    Free Spins Bonus
                    Free Spins Bonus

                    A free spins bonus is a slot-specific bonus that offers free spins on specific slot games when you make a deposit. Once you have made a qualifying deposit, your free spins will be added to your account, giving you the chance to play some of the most popular online slots for free.

                    Trophy

                    Slot Tournaments

                    Another slot-specific promotion that a casino may run is a slot tournament. These tournaments encourage players to play specific slots games UK, earning points as they do so. The players who earn the most points at the end of the tournament can be rewarded with cash prizes or bonus funds.

                    Wagering Requirements

                    When using your casino bonus, it’s important to be aware of the wagering requirements in place. Wagering requirements (or playthrough requirements as they’re sometimes known) dictate how much you need to use your casino bonus before any winnings are eligible for withdrawal.

                    For example, if I receive £10 in bonus funds with 30x wagering requirements, I would need to play £300 worth of casino games before I can make a withdrawal. The wagering requirements of a casino bonus are typically 20x-40x, although some special offers have wagering requirements as low as 1x, whereas others have requirements of 50x or greater.

                    Real Money Slots vs. Free Online Slots

                    When playing online slots, you can either play for real money or for free. Before we do a full comparison, let’s take a closer look at each of these options:

                    Real Money Slots 

                    When playing online slots for real money, you’re risking your hard-earned money to potentially win some of the casino’s money. You need to understand that these games have a built-in house edge, meaning that the casino will always win in the long run. However, many players prefer playing slots for real money, as it offers an increased emotional investment, as well as the chance to walk away a winner in the short term.

                    Free Slots 

                    When playing free online slots, you are not risking any real money while you play. However, this also means that any winnings you earn aren’t real and cannot be withdrawn. Many players use free slot games as a way to familiarise themselves with a new game or to test out a new betting strategy. 

                    If you’re new to online slots, we recommend that you play free slots before playing for real money.

                    Now that we know a little more, let’s look at a quick comparison:

                    Jackpot Slots

                    Jackpots are special prizes that can be won when playing specific online slots (aptly called jackpot slots). There are several different varieties of jackpot slots available to play. These three are the most popular:

                    Sweepstakes Casinos

                    Fixed Jackpots

                    As the name suggests, fixed jackpots are always the same amount, regardless of the bet size. To trigger it, you typically need to match a specific combination of symbols on your game board. For example, if you match five jackpot symbols across one of the available paylines, you will win the jackpot.

                    Release Year

                    Daily Jackpots

                    Some slot games offer daily jackpots that must be won within a 24-hour time frame. These jackpots are progressive, which means that the total increases as more players play the slot, but also have a guaranteed minimum amount that you can win each day.

                    jackpot

                    Progressive Jackpots

                    Progressive jackpots grow over time – a small percentage of each bet is added to the prize pool, increasing the amount you can win over time. These games typically offer multiple jackpot prizes, with the highest jackpot available to players who bet the maximum.

                    UK Slots Mobile Experience

                    Due to the popularity of mobile casino gaming, we’ve seen a marked increase in the number of online casinos offering online slots on a mobile gaming platform. However, not all mobile casinos are created equal, and there are some sites that offer a much better mobile gaming experience than others.  

                     If you’re considering playing online slots at a mobile casino, here are a few things to consider. 

                    StarGame selection Not all casinos offer the same selection of games on their mobile gaming platform as they do on their PC gaming platform, so make sure the games you want to play are available on mobile. 

                    StarWebsite layout It’s easy to make optimisation mistakes when creating a website for a smaller screen, leading to text overlap, distorted images, and other issues that make a site difficult to navigate. Before committing to a mobile casino, see how the site runs on your device. 

                    StarPerformance optimisation As mobile apps offer lower processing power, getting good performance can be difficult. Many slot providers intentionally optimise their games for mobile devices, so check to see whether or not your favourite games are suitable for mobile play. 

                    StarApp availability – Many of the top online casinos offer dedicated mobile gaming apps that allow you to enjoy hundreds of slot games. Apps are often better optimised for both layout and performance, making them a desirable option for mobile slot players.

                          Online Slot Payout & RTP

                          When choosing which online slot to play, a slot’s payout and RTP rate are two crucial factors to consider. While many people use the terms interchangeably, the two terms have different meanings: 

                          Real Money Casino

                          Payout

                          A slot’s payout refers to the amount of money a player can expect to receive when they win. Many slots have varying payouts depending on the symbols matched, leading to a minimum and maximum payout.

                          Percent

                          RTP (Return to Player)

                          A slot’s RTP rate is a percentage that represents the amount of money that will be paid back to the player in the long run. While the payout of a slot will vary from spin to spin, the RTP rate looks at the average – if a slot has a 96% RTP rate, it means that in the long run, each player will receive back £96 for every £100 they wager.

                          High RTP Slots

                          To save you the effort of looking at the RTP rate of every single slot, our experts have collected ten of the most popular high RTP slots available at UK casinos. Take a look: 

                          Online Slot RTP Rate Software Provider 
                          Starburst 96.09% NetEnt 
                          Reel Rush 96.96% NetEnt 
                          Jack Hammer 96.96% NetEnt 
                          Joker Strike 96.46% Quickspin 
                          Guns N’Roses 94.07% NetEnt

                          Online Slot Volatility

                          Bonus RoundWhen talking about the RTP rate of a slot, it’s also important to talk about a slot’s volatility. While the two concepts are different, they do interact with each other to influence the game.  

                          A slot game’s volatility level ranges from low to high: a low volatility slot will pay out more frequently but for lower amounts, while a slot with a high volatility level will pay out higher amounts less frequently. Volatility and RTP rates are often linked; slots with a lower RTP rate will often have higher volatility, whereas high-RTP slots will often have lower volatility. 

                          Overall, if you aren’t risk-tolerant, we recommend you play low-volatility slots, and vice versa.

                          Slots Online Software Providers 

                          When choosing online slots, it’s important to look at the software provider who has made the game.

                                            One of the most important things to consider when choosing an online slot casino is the variety of slot games they have available. Make sure you check out their slot library and examine the quantity, quality, and variety of games on offer.

                                                                                                  Bonus Feature  Bonus Feature and SpinsOne of the more exciting aspects of online slot games UK are extra features that can either be triggered at random, or by landing several bonus or scatter symbols. The features can range from free spins, pick-and-click games, a new set of reels with different symbols and much more.
                                                                                                  Real Money Casino  Fixed JackpotUnlike a progressive jackpot that grows with each spin, a fixed jackpot is usually based on a pay table and has a set payout.
                                                                                                  Online Craps  MultiplierThis will increase the size of a win by the multiplier. For example, £2 win with a 3x multiplier will payout £6
                                                                                                  Bet and Get Bonus  Maximum and Minimum BetAll online slot games have a minimum and maximum bet that you can wager per spin
                                                                                                  Percent  Return to Player (RTP)Based on thousands of games, the RTP is the average expected return to the punter. The average RTP is around 96.5%, which means that if you played with £100, you could expect to finish playing with £96.50. It’s important to note that the RTP doesn’t guarantee that you’ll end up with 96.5% of your, where’s the fun in that, but if you took a look at all the players playing this game, that would be the average return.
                                                                                                  Pay Table  Grid vs. PaylineThese are the two main types of slot games. A game with a set number of paylines will require that symbols are aligned on that payline to create a win. In a grid, or Ways to Win system, the matching symbols just have to land on adjacent rows to create a win.
                                                                                                  Payout  PayoutThis is the value of a symbol, the more symbols you have in a row, the higher the payout.
                                                                                                  Reels  ReelsThis is taken from the one-armed bandit slot machines that had 3 reels with the symbols on them. Online slot games don’t technically use reels in the mechanisation but kept the terminology.
                                                                                                  Scatter  ScatterA symbol that pays out without having to be along a payline or on adjacent reels. Scatter symbols can often only appear on certain reels and can trigger a bonus feature.

A game with a high volatility is considered a higher risk than low volatility games since they don’t pay out as often.

The average RTP is around 96.5%, which means that if you played with £100, you could expect to finish playing with £96.50. It’s important to note that the RTP doesn’t guarantee that you’ll end up with 96.5% of your, where’s the fun in that, but if you took a look at all the players playing this game, that would be the average return.

A game with a set number of paylines will require that symbols are aligned on that payline to create a win. In a grid, or Ways to Win system, the matching symbols just have to land on adjacent rows to create a win.

                                                                                                  Whether you’re playing in a payline or grid style, to win at online slots, you’ll need the symbols to randomly land in a certain formation to trigger a payout. There are some features and jackpots that can be awarded at random, but this will vary per game.

                                                                                                  As online slots are purely a game of chance, there are no strategies you can use to win in the long term. However, by fully understanding the rules, using bankroll management, and picking favourable slots, you give yourself the best opportunity to win in the short term.

                                                                                                  Any time you get a matching set of symbols in a winning combination, it will trigger a payout based on the value of the symbol. The pay table will typically be based on the line bet, as opposed to the overall bet. What this means is that if you’re playing a 20 payline game, make a bet with a £1 coin, meaning your total bet is £20 and get 5 symbols in a row with a payout of 100x the payout will be £100 as opposed to £2,000.

                                                                                                  Unlike progressive slot games that have a constantly changing jackpot, Flat Top machines have a fixed top jackpot.

                                                                                                  No. All the sites we recommend are regulated and licensed in the UK, ensuring fair play. All the slot games use a Random Number Generator (RNG) which is an algorithm the guarantees the slot game conforms with the preset odds and RTP.
