Expanding on the established mechanics of Novomatic's Book of Ra, Play'n Go expands the action in Book of Dead. Featuring a boosted RTP of up to 96.21%, the title has a much higher chance of spinning a winner than Novomatic's original 92.13%.

The Dog House - Pragmatic Play (96.51% RTP)

It's time to go ape with the premiere primate in King Kong Cash from Blueprint. This primate packs a punch with up to a 50,000x max win and up to an impressive 14 unique bonus games to unlock.

Gonzo's Quest - NetEnt (95.97% RTP)
Like Starburst, another Netent slot on our top slots 10 list, Gonzo's Quest is a well-established fan favorite in the UK.

Sweet Bonanza - Pragmatic Play (96.60% RTP)
Sweet Bonanza offers players plenty to sink their teeth into! The title is an innovator of the popular 'Pay Anywhere' feature where symbols can pay regardless of position on the reels. Sweet Bonanza's Medium volatility also means there's a fair chance to trigger a win on any given spin; with cascading reels on every win for even more chances to match consecutive wins when they trigger.
Money Train 2 - Relax Gaming (98% RTP)
Expanding on the Wild West action of the original, Money Train 2 adds even more to its arsenal by upgrading the total number of bonuses from 5 to a whopping 11 in the bonus game. The title also boasts one of the highest RTPs in the UK market with 98% and coupled with its 50,000x max win; there are chances to bag some big wins.
Rainbow Riches - Light & Wonder (95% RTP)
A favourite of the land casino, Rainbow Riches has cemented itself as an easily recognised slot in the game.

How we rate UK slots sites
Game selection
Naturally, the slot game selection offered is a crucial element in our rating system for UK slot sites. Our benchmark for a slot site to be considered one of the best is 1000+ games to give players the widest possible selection. Sites like Pub Casino and All British Casino house an extensive collection that continues to grow almost daily; so why settle for any less than the best?
Reputation and regulation
Reputation and regulation are vital to how we recommend online casinos. We are always looking for licensing from the United Kingdom Gambling Commission and proof of regulation from eCOGRA to ensure we are only recommending the most legitimate casinos in the market.
Bonuses and promotions
Every online casino has something to offer and we make it a priority to recommend only the best available.
For a slot site, Free Spins are what we look for first and foremost with sites offering on top titles like Big Bass Bonanza.
When it comes to bonus cash amounts, 100% up to £100 is the standard, so we like to see that as a welcome bonus to get the ball rolling - with anything over that being a major plus to any casino.
Mobile compatibility
Since 2020, over 50% of all casino users are spinning on their favourite titles on the go. Therefore, mobile compatibility sits as of particular importance when it comes to how we evaluate a casino.
While a mobile site is a great start, a mobile app will help a slot casino score highly! The best mobile casinos in the UK like All British Casino offer native app functionality that can further streamline your casino play and get you right into the action in seconds.
Customer support
If you ever have any queries or issues at one of our recommended slot sites, they can be resolved quickly and easily by their experienced customer support team who will be on hand to help you out.
All will offer an email support system, with many offering round-the-clock live chat or a telephone number to talk to someone directly. Both of these additional customer support methods go a long way as solidifying a casino as a top choice for UK players as it streamlines the experience and gives options on how to get the best solution for your query.
How to play online slots
Slots are the #1 most popular type of online casino game in the UK and it's not hard to see why. Online slots are simple, fun, and can be packed with tons of unique features and bonus games. Whether you're a slots veteran or delving in for the first time, check out our step-by-step guide and you'll be spinning like a pro in no time.
- 1Choose one of the top-rated slots sites in our toplist above and complete their sign-up process (most will come with an extra bonus for new sign-ups like Free Spins or bonus funds to help get you started)
- 2Once signed up, access the "Games" section of the casino
- 3You can filter slots based on game providers, slot type, or theme. Select a game of your choice and wait for it to load up.
- 4Check the paytable options on any game to get an understanding of how to play, the available paylines and all of the exciting bonus features to discover.
- 5Choose your bet level by using the '+' or '-' press spin to begin. Higher bet values do mean higher potential wins, but it makes bigger losses more likely too! Play responsibly and always stay within your means.
- 6Once the reels have finished spinning, wins are calculated with 3 or more matching symbols being a standard for triggering a win.
- 7Some slot games can include bonus base game features that can trigger on any spin including win multipliers, cascading reels or special Wilds that will substitute for any symbol in a win.
Online slot mechanics & features
There are two elements of online slot gameplay, the base game and bonus rounds!
?? Base game
The base game in a slot is where you start whenever you load up an online slot. In this mode, you will attempt to turn your spins into cash by lining up symbols on the slot reels in what is known as "paylines" or "win lines".
Different symbols will have money values with higher-value symbols offering you better payout amounts if you line them up. Paylines and symbols will vary from game to game with some offering more than others.
As well as standard paying symbols, most slots also have special symbols that can add extra surprises to your gameplay. The most common you can find on any spin are "Wilds", "Multipliers" and "Scatter Symbols".
- "Wilds" can be found on most slot games and can act as any paytable symbol when a win is triggered on the reels. Wilds can also sometimes have cash values of their own and be matched as their own symbol type.
- "Multipliers" can appear in popular slot titles as part of existing symbols or as their own unique symbol. When matched on a winning spin, Multipliers can add to your total win value by adding a times multiplier to the value. No need to bust out the calculator as you can see your wins doubled, tripled, or even supercharged with up to a 10x win multiplier.
- "Scatter Symbols" can be found on many slot games and are the key to unlocking special free spins modes or bonus games. Match 3 or more anywhere on the reels and you've punched your ticket to some extra games.
?? Bonus rounds
Bonus rounds come in many forms and generally take the form of a "free spins" round. You will be awarded a number of spins that do not deduct from your cash balance and tick down by 1 each time you spin.
During a free spins round, any number of other special features can trigger to boost your overall winnings during the round. At the end of the free spins round, you will be awarded the total amount won in the free spins round directly into your casino credit.
Titles like Big Bass Bonanza or Immortal Romance further spice up the experience with additional features unique to their free spins mode. Big Bass Bonanza features an exclusive 'Cash Collect' feature that allows for up to 2,000x in instant prizes while Immortal Romance has up to 4 unlockable free spins modes; each with their own set of character-themed bonuses like multipliers and Wild symbols.
During a bonus round, you can activate a number of additional features including:
- Stacked Wilds- Prominent in titles like Book of Dead and Eye of Horus, some bonus rounds will add Wilds that will stack to turn entire reels Wild; covering multiple paylines for wins.
- Unlockable Reels- Some bonus rounds will give you even more space to spin with additional reels and expanded paylines for even more chances to win.
- Random Modifiers- Can be found in a number of titles and will add special enhancers to your spins including random Wilds, win multipliers, giant paytable symbols, extra spins and more.
- Win Boosters- Games like Enchanted Prince and Sugar Train award an instant multiplier for every win during the free spins mode to help boost your total values.
Other slot game features
The below features can appear either in the base game or the bonus round, depending on the game you are playing. Many online slots will offer some of these features but each game is different and will offer varying features including:
| Feature | How it works |
|---|---|
Cascading Reels | Symbols that disappear when matched in a payline causing the reels to drop down and add even more symbols onto the reels. These new symbols can then cause a medley of winning combinations with each consecutive win adding even more symbols. |
Win Multipliers | An element of the game where winnings are multiplied gradually (1x each win) as your number of consecutive symbol matched grows. |
Respins | A free new spin that occurs after a paid or bonus spin due to an in-game event, giving you a second chance to win on that spin. |
Expanding Wilds | Wilds that extend to cover whole reels when triggered to turn the entire reel Wild and give a higher chance of activating a winning payline. |
Exploding Wilds | Wilds that explode when triggered, causing new symbols to appear on reels close to the exploding wild. |
What our experts say
"Be mindful that not all slot games offer bonus rounds. Classic slot titles like 7s Deluxe or Burning Wins streamline the experience with just 5 available paylines and no bonus game to keep that retro slot machine feel. Always check the paytable to get an idea of what a game has on offer when it comes to bonus rounds."- Lewis Crane

UK slots software providers
The online casino scene in the UK is packed with iconic titles from some of the most recognisable software providers worldwide. When it comes to video slots, these guys know their stuff with high production value and a wealth of experience that goes into the creation of every curated online slot game.
??Expert insight: "Remember that not all slots are the same as each provider loves to add their own signature touches to each title. Play a variety and you might start picking up on some of the flavours that separate a Pragmatic Play slot from a Blueprint slot".
Here are some of our favourites to look out that can showcase an outstanding games library at a top online casino:
Blueprint
Hitting the gaming scene in 2001, Blueprint has cemented themselves as one of the UK's top software providers with top performing titles like Fishin' Frenzy, King Kong Cash and Eye of Horus.

Netent
A powerhouse in slot game innovation, most of the top 20 UK slots played every year have come from their studio, including classics like Gonzo's Quests and Starburst. In 2020, Netent was merged into the Evolution casino brand to bolster their slots portfolio alongside other studios like Red Tiger and NoLimit City.
Online Slots Technology & Safety
All slots from top software providers utilise RNG technology to guarantee the fairness of every round and this is tested over 1,000,000+ spins before a game is deemed ready to launch. Every game also uses encryption software to ensure the safety of player information and avoid fraudulent activities.
In terms of functionality, a majority of online slots are built with HTML5 to ensure high quality gameplay and compatibility on a majority of modern devices including desktop, mobile and tablet.

Slots strategy
Online slots are entirely reliant on chance, but that doesn’t mean there aren’t things you can do to put yourself in a better position to win. Experienced players follow a distinct strategy, like only playing games with the highest payout percentages, practising their bonus rounds and knowing their paylines inside and out. Follow these guides to give yourself the best possible chance to win.
What is a payout percentage?
As a slots player, the payout percentage (RTP) indicates how much of your money bet will be paid out in winnings. Every slot and casino game has an RTP percentage that can be found in the paytable with most slots in the UK having an average of 95%-96%+ depending on game and provider.
RTP isn't the only factor determining your payouts as every slot game will also include a volatility level from Low-High. Volatility affects the likelihood of a standard spin being a winner with lower volatility slots winning more often than higher volatility slots.
The tradeoff is that, while low volatility slots pay more often, high volatility slots like Book of Dead award a larger average payout when winning spins are recorded.
We have a page dedicated to casinos with the best payouts so you can find the best places overall for finding games with the highest theoretical win potential.
??Expert insight: "Remember that RTP is calculated on average over 1,000,000+ spins and is a guideline on what you could win. Your personal RTP can be higher or lower depending on how you play as RNG still plays the biggest factor on whether a spin will be a winner."
Check out the table below for a clear understanding of how RTP & volatility can affect your average slots experience including what makes them different.
RTP & Volatility- what's the difference?
| RTP (Return to Player) | Volatility |
|---|---|
RTP indicates the average monetary return a player can expect when playing a slot game over a long period of time. | Volatility indicates the likelihood of a slot triggering a win on any given spin and also has a factor in determining the total win value of each successful spin. |
RTP is calculated as a percentage out of 100% with most slot games ranging from 88%-96%+ depending on market and configuration. | Volatility is measured on a scale of Low-High with each slot having 1 of 5 preset volatility levels from Low, Low-High, Medium, Med-High, or High |
Higher RTP games are objectively better for your gameplay than lower RTP slots as the chances to win are statistically higher on average. | While volatility has an impact on your playing experience, no specific volatility is objectively better and will depend on what you prioritise as a player between frequent wins and high value wins. |
For example: A slot with an RTP of 98% will, on average, return ￡98 for every ￡100 spent on bets. | For example: A low volatility slot will have a higher chance of triggering a win on any given spin but the overall payout values will be lower than a high volatility slot. |
Top 10 highest RTP slots for 2024 - top payout slots UK
Every online slot has a built-in RTP percentage that is different for each game played. In the UK, 95%+ is seen as the standard for a solid game RTP with titles frequently hitting the 96%+ range to better cater to players.
The following slots offer some of the highest RTP (Return-To-Player) in the UK to help maximise your chances of spinning a winner. Spin on the best RTP online slots including:

Online slot sites – advantages and disadvantages
Advantages
- Huge range of games - Slots are the most widely developed games on the market meaning that even smaller-sized slot sites will still offer dozens of games. Games can also differ quite heavily in terms of mechanics, themes and bonus rounds meaning there's something for everyone.
- Easy gameplay - The gameplay on slots is generally very easy. While some games offer bonus rounds or features that add extra elements, they are easy to get started on.
- Huge win potential - This is particularly true for progressive slots but even normal slots can offer massive max wins that can pay out huge amounts. Standard titles from Blueprint can offer up to a whopping 50,000x max wins meaning that you don't necessarily need to pop a super progressive jackpot to win big.
- Low-cost entry-level - Some slots can be played for as little as 1p meaning games are accessible for anyone on any budget.
- Always new games - New slot games pop up almost daily meaning there is always something new and exciting on the cards.
Disadvantages
- Strategy is limited - While there is some strategy involved in slots, RNG still has the biggest impact on when a slot game wins or not. Compared to table games like blackjack or roulette, you are limited in how much you can control the results of a round.
- Low odds - While some slots have higher RTPs, slots generally have very low odds when compared to other casino games like blackjack (99%) or roulette (97%+).
- Lack of social interaction - Unlike live games where you can interact with other players or the game dealer, slots are a solo experience with no cooperative or social element outside of certain tournaments.
UK slots FAQs
How do online slots work?
The basic concept of slots is to spin the reels and match up the symbols along paylines to win. When you're playing slots online at any of our top online casinos, you can find the instructions on how to play in any game's paytable options.
Can I play slots for free?
Yes. Most online slots sites will offer players the option to play some free slot games. This means you won't have to deposit any money to get started, you can simply enjoy the game for fun. Keep in mind that playing free slots does not allow you to play for real money; meaning any winnings are purely for fun.
What should I look for in an online slot casino?
After security and legitimacy (there are unfortunately a lot of rogue online casinos out there) you want to look at the payout percentage of an online slot. This is the percentage of the wagers paid in that the casino pays out in winnings. This is especially important if you're planning on playing for real money. A higher payout percentage generally means more money back in your pocket.
What’s a progressive jackpot?
This is a jackpot that builds up over time and then pays out a big sum of money to a single player. Most online slots casinos offer progressive jackpot slots so it's worth keeping an eye on the jackpot total and how frequently the game pays out. Progressive jackpots include mechanics like WowPot, Dream Drops and Jackpot King.
Can I win real money playing online slots?
Yes you can. All online casino sites offer a wide selection of real money slots winnings can be withdrawn for real cash prizes. Just make sure you play within your means and understand how factors like RTP can affect the total payout potential.
How do welcome bonuses work?
Welcome bonuses reward players when they make their first real money deposit. The exact terms and requirements vary from casino to casino and some offers that seem too good to be true probably will be. Before you commit your cash, we recommend checking the wagering requirements of the online slots casino you're planning to play at. These will explain how much of your money you're required to deposit upfront, and what you can expect to receive in return.
Are online slots rigged?
No, all regulated online slot machines are completely fair. Slot machines are rigorously tested before being assigned an RTP value to ensure that the results are random on each and every spin. To guarantee fair play, only choose slots from approved online casinos, such as those we list on this page. Playing at any of these will give you a fair chance of winning.
Does the amount I deposit at a slots site influence the payout?
Bigger bets have no affect on the chances of winning but can mean you return more winnings when wins are recorded. Paytable values are calculated based on your bet level meaning that wins at a higher bet level will return more cash. Be mindful to always play within your means and only play at high bet levels if your bankroll allows it.
Do people actually win money with online slots?
Of course. People are winning money on slot machines every single day - with some earning big prizes. Every slot that is properly regulated and on the books of a licensed casino has a chance to award cash prizes on every single spin with some slots having top payouts of over 100,000x depending on the results.
Are there specific UK slot site regulations?
As per UKGC regulations, there are several elements of slots that are banned at UK slot sites. For example, Quick Spin and Auto-Play features, which allow for the game to play with little input from the player, are banned on UK slots. Bonus and feature buys are also prohibited.
Aside from these in-game regulations, players cannot use credit card payments to fund their UK slot site accounts as to avoid players gambling with money they might not have.
