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.
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:
Themes and Graphics
We look for games that have cutting-edge graphics and well-designed themes, giving you a top-class visual experience.
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.
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.
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.
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.
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 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.
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.
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.
- 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.
How to Play Online Slots
Another reason why online slots are so popular in the UK is that they can be enjoyed by all casino gamblers, no matter your experience. You don’t need to learn any complex strategies or memorise the value of different cards, you can simply load the game and start playing.
If you’re new to the world of online slots games and want to know where to begin, you’re in the right place! We’ve created a step-by-step guide that will walk you through playing online slots for the first time.

Online Slots UK Varieties and Game Types
Almost all sites in the UK will offer hundreds of online slots, each with its own design, themes, animations, features, and gameplay, giving you unparalleled choice.
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.
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.
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.
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.
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.
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.
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.
Online Slot Features
Online slots offer a variety of features that enhance the gaming experience. While there are dozens of unique features available, we’ve highlighted the most popular features found in the best UK slot games.
Wild Symbols
These are symbols that can replace almost any other symbol on the board, making it easier to find a winning combination.
Expanding Symbols
These symbols will expand across entire reels or even multiple reels, giving you a higher chance of finding a winning combination.
Free Spins
Some slots offer free spins with real money winnings if you find a specific number of Scatter symbols on the game board.
Bonus Rounds
Other slots offer bonus rounds where players can win instant cash prizes.
Bet Limits
Each slot has a minimum and maximum bet limit in place, allowing you to determine how much you want to risk each spin.
Auto Spin
To save you from having to click the Spin button dozens of times in a row, some slots offer auto-spin that allows you to repeat the same spin for a set number of times.
Bonus Buy
Tired of spinning for hours and not finding bonuses? Some online slots allow players to buy their way into a bonus round, giving them instant access to potentially huge rewards.
Double or Nothing
Some slot games allow players the opportunity to gamble their winnings at the end of each spin in a fun double-or-nothing game.
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.
- 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.
- 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.
- 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.
- 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.
- 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!
- Hit up smaller jackpots: Playing games with regular jackpots over progressive jackpots will offer a better chance to land bigger wins.
- 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.
- 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.
- 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.
- 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.

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
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.
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
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.
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:
- Potential to win real money
- Risk of losing real money
- Access to casino bonuses and promotions
- No opportunity to practice or test a game without the risk of losing money
- No potential to win real money
- No risk of losing real money
- No access to online bonuses and promotions
- Players can test new strategies and try new games with zero risk
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:
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.
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.
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.
Best Jackpot Slots
Our experts have listed their top three jackpot slot games in the table below, so be sure to give them a spin:
Slot Name | RTP | Progressive? | Features |
Mega Moolah | 88.12% | Yes | Free Spins Multipliers Wild Symbols |
Dead or Alive | 95.03% | No | Free Spins Sticky Wilds |
Jackpot Giant | 91.25% | Yes | Wild Symbols Bonus Game Free Spins |
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.
Game 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.
Website 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.
Performance 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.
App 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:
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.
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 |
Butterfly Staxx | 94.05% | NetEnt |
Fruit Shop | 94.05% | NetEnt |
Mega Joker | 95.05% | Novomatic |
Online Slot Volatility
When 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.
To give you an idea of the companies to look out for, we’ve listed five of the biggest online slot developers in the industry.
NetEnt
Having launched back in 1996, NetEnt has been creating top-quality online slots for more than 25 years. They’ve become renowned as one of the best slot developers in the world, creating a variety of popular titles such as Starburst and Gonzo’s Quest.
Pragmatic Play
A relatively new face in the casino development world, Pragmatic Play was founded in 2015 but has quickly grown to be one of the most recognisable game developers. With popular titles such as Wolf Gold, Sweet Bonanza, and Great Rhino under its belt, Pragmatic has found success with simple, well-designed slots that offer interesting features.
Play’n Go
Play’n Go is another slot developer that’s been around for years, having launched in 2005. They started out with the ambition to be the best gaming entertainment supplier around, and you could certainly argue that they’ve achieved that goal! With dozens of well-known slot IPs such as Book of Dead and Rise of Merlin, they can be relied on to create high-quality online slots.
Quickspin
A Swedish game developer that started in 2011, Quickspin is known for its range of innovative slot games that combine engaging gameplay with immersive storylines. Games such as Big Bad Wolf, Sticky Bandits, and Sakura Fortune are commonly found at the best UK slot casinos and are a favourite amongst UK players.
Thunderkick
Thunderkick launched in 2012 out of a tiny studio in Stockholm with a dream of creating fun, exciting casino games. Thunderkick games are easily recognisable due to their distinctive designs and quality animations. Popular Thunderkick titles include Pink Elephants, Birds on a Wire, and Esqueleto Explosivo.

Online Slots UK Glossary
Here are some key terms for players to know before playing casino slots online.
Bonus Feature and Spins | One 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. |
Fixed Jackpot | Unlike a progressive jackpot that grows with each spin, a fixed jackpot is usually based on a pay table and has a set payout. |
Multiplier | This will increase the size of a win by the multiplier. For example, £2 win with a 3x multiplier will payout £6 |
Maximum and Minimum Bet | All online slot games have a minimum and maximum bet that you can wager per spin |
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. |
Grid vs. Payline | These 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 | This is the value of a symbol, the more symbols you have in a row, the higher the payout. |
Reels | This 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 | A 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. |
Volatility | Also known as variance, this is a way to measure whether a slot game will pay out small wins frequently or has bigger wins but less often. A game with a high volatility is considered a higher risk than low volatility games since they don’t pay out as often. |
Wild | It can substitute for any regular symbols to create a win. Some slot games have special wild symbols that can expand or multiply, but that depends on the specific game. |
UK Slot Games FAQ
How do you win at online slots?
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.
