Guide to Choosing the Best Slot Sites in the UK
We understand that every online slot player has a different approach, style, and gaming budget. That’s why we give you a complete range of the best slot sites in the UK to pick from.
Our experts have handpicked the UK online casinos that offer the best choice when it comes to slots. From fantastic themes and bonuses to top-tier bonus features and free slots, you’ll never be bored with these sites in your locker.
We’ve reviewed and rated the most trustworthy UK slot sites based on first-hand research. Armed with this guide, you’ll only be playing at the best online casinos from now on!
How We Rate the Best Slot Sites in the UK
We check out hundreds of top UK slot sites to see what games they offer, how good they are, what the user experience is like, and what bonuses they have. If you're wondering how we decide which ones are the best, here's how we do it.
Step 1: One of our slot experts opens an account with a casino. This way, they can judge the simplicity of the sign-up process and the security provided.
Step 2: They will then test and compare online casino bonus offers. If a casino gives a bonus as rare as a no deposit free spins welcome offer, it gets an extra star.
Step 3: Using payment methods available to UK players, the reviewer makes a deposit. This lets them test the site’s games for fairness, speed, and visuals.
Step 4: Once the reviewer gets a win, they'll ask for a payout. This helps us check payout speeds. It's also a good time to talk to the support team and see how helpful and friendly they are.
Step 5: If a website really stands out, it gets a bonus point from us. For example, the same casino can be a great slots site and one of the best online poker sites at the same time.
Step 6: The best online slot sites in the UK work well on desktop, Android, and iOS devices. We check if that's true when reviewing the casino.
We also pay attention to new slot sites UK players can join, so we'll alert you as soon as they launch. Plus, we track established sites to make sure they haven't rested on their laurels.
How to Sign Up at a Slot Site
If you want to play the best UK slots, you need to sign up with a casino. It's quick and easy, usually taking just a few minutes. The sign-up process varies from casino to casino, but these steps are pretty standard:
To begin, select a casino you like from this page and click on the 'Visit Site' button or similar.
At this point, some casinos might want you to confirm who you are. It's just a standard process called Know Your Customer (KYC). If you can't do it right away, you might still be able to finish this step before withdrawing. But some sites only let you deposit once they've verified your identity.
Now, go to the cashier and deposit using your preferred payment method.
If the casino offers welcome bonuses, you can now claim them. But check the main terms, as you may need a promo code.
You're all set. Select a slot that appeals to you and check the payout table. It will tell you everything you need to know about the slot.
Set your coin value, aka your bet, and the maximum bet per line if you are playing a progressive jackpot slot. Then, hit the spin button.
Keep playing until you're ready to cash out, as long as you're having a good time and staying within your limits. Don't forget that all wins read from left to right.
Finally, you can visit the cashier to make a withdrawal. Choose your preferred withdrawal method, enter your desired or maximum amount, and confirm. Withdrawals are rarely instant, so check the banking page for details.
Understanding Mechanics and Features of Online Slots
Before you start spinning the reels, it’s essential to know that not all slots are created equal. Software developers use a dazzling array of game mechanics that can have a big impact on your win potential and gameplay.
Let’s take a look at the key components that make up any UK online slot. Having a solid understanding of these can help you quickly level up your slot gaming next time you play.
Base Game Slot Mechanics
Any slot will load up in the base game, where you’ll instantly see the game’s standard symbols and reel setup. To know each symbol's value and winning combinations, tap the info button to display the slot’s paytable.
To start spinning the reels, you just need to select a bet size, also known as the spin value, and away you go. Adjusting this lets you personalise your gameplay to fit your budget.
How spin value is calculated can differ depending on the slot, but it usually includes a few key factors like:
Coin Value: Set your coin value, typically starting from £0.01.
Bet Level: The number of coins you want to wager per spin.
Paylines: Choose how many paylines you wish to activate, if available.
You’ll typically need to land at least three matching symbols to trigger a win in most slots. Some games may allow a win with just two of the highest-paying symbols.
In traditional slot games, wins are made by matching symbols in a line across the reels from left to right. In modern online slots, you can achieve a win in many different ways thanks to some unique payout structures, such as:
Pays Both Ways: You can create winning combinations from left to right and right to left.
Cluster Pays: Create wins when five or more matching symbols form a cluster anywhere on the grid.
Anywhere Pays: Matching symbols can be located in any position across the game grid.
Scatters: Sometimes known as Bonus symbols, landing three or more of these in any position will trigger the slot’s bonus game. In many games, you’ll get additional rewards the more you land.
Wilds: These symbols will substitute for other symbols, except Scatters or bonus symbols. They help make it easier for you to form winning combinations.

While the base game gives you more frequent and occasional big payouts, the bonus round is where you’ll find the biggest win potential. These slot features will have a range of high-value symbols and multipliers to boost your prize pot.
To trigger a bonus round, you usually need to land three or more Scatter symbols on the reels in the base game. Once unlocked, here are some of the enhanced features and multipliers you can expect to encounter:
Bonus Wheels: Before a bonus round begins, you might need to spin a wheel to see which type of special features you’re playing with.
Bonus Gamble: Some slots allow you to gamble your awarded bonus features for a bigger one. Be aware you might lose it all, as it’s typically double or nothing, and you’ll land back in the base game!
Link & Win: A respin feature, also known as Lock 'n Spin or Hold & Spin, that awards you with special free spins. The spins reset with each cash symbol you land until you run out of spins or there are no more cash bonuses to collect. The symbol amounts are totalled and paid out at the end of the feature.
Retriggers: By landing scatter symbols, you can get additional free spins during a bonus round.
Upgraded Symbols: In some slots, you can upgrade selected symbols or eliminate lower ones during the bonus feature. This instantly increases your winning potential.
Ladder Climb: Collect specific symbols and progress up the slots reward ladder for bigger prizes.
Types of Online Slots
The world of online slots is always growing with new themes and exciting features. It used to be all about basic fruit slots, but now there's a whole universe of games in different categories.
Classic Slots
f you feel like a nostalgic spin or just like to keep things simple, classic slots are by far your best bet. These games are found at nearly all UK online casinos and feature three to five reel layouts and familiar symbols like bars or fruits. Classic slots are the go-to choice if you hanker for some straightforward gameplay with an old-school vibe.
Video Slots
Video slots feature stunning graphics, immersive storylines, and interactive features. These five-reel games are typically packed with exciting bonuses and free spins. The best Video slots are based on a wide variety of engaging themes, from popular movies to ancient civilisations.
Megaways Slots
Megaways is a random reel modifier created by Big Time Gaming that changes the number of symbols appearing on each reel. You still win by landing identical symbols on adjacent reels, but you don’t need to line them up along specific paylines. Megaways slots create up to 117,649 possible ways to win per spin. This makes them ideal if you love unpredictable gameplay and massive win potential.
High Volatility Slots
High volatility slots are a great option if you enjoy big thrills and even bigger potential payouts. While wins may be less frequent, they can be massive when they hit. If you’re after high-stakes action and can handle the wait, high volatility slots will keep you on the edge of your seat.
Scatter Slots
These entertaining slots feature special scatter symbols that can help boost your wins. Landing three or more scatter symbols will typically trigger the slot’s bonus feature or even the game’s jackpot. Scatter slots will usually have a strong theme, such as ancient Egypt or mythical creatures.
Progressive Jackpot Slots
If you’re looking for slots to play for real money with life-changing potential, progressive jackpot slots are the way to go. These games pool a percentage of losing bets into a jackpot that keeps growing until someone wins. Hit the right combo, and you could take home a multi-million-pound payout!
Fruit Machine Slots
If you want to go back to where it all began, fruit machine slots are the timeless classic in the realm of slot games. Their juicy fruit symbols and simple three to five-reel setup can give you some basic yet engaging gameplay anytime. If you just want to spin the reels without learning any complex features, fruit machines are always a winner.
Slingo
If you want the perfect blend of slot games and bingo, Singo slots combine the best of both worlds. You spin reels to match numbers on a bingo card, hopefully accumulating wins and prizes. If you’re after a fresh twist on the classic online casino game, take Slingo slots for a spin.
The Best Online Slots in the UK in 2024
The best online slots in the UK depend on personal preference. But some have gained widespread popularity over the years. They include classics like Gonzo’s Quest, Mega Moolah, Starburst, and Rainbow Riches.
You can test out demos of classic and new online slots by signing up with the casinos listed below. Just remember to note down which sites offers which slot so you know where to play them.
In a progressive jackpot slot, the main prize gets bigger and bigger until someone hits the jackpot. And when that happens, the jackpot starts to build again. Only a few UK slot players have been lucky to win big in the past few years by playing these games at UK sites.
An English soldier, Jon Heywood, is just one of them. In 2015, he hit a huge £16 million jackpot while playing the Mega Moolah slot. He bet only 25p on a spin and scored the jackpot, landing himself a place in the Guinness Book of World Records.
A Belgian player has since topped Jon Heywood’s win, playing Mega Moolah. But many slot lovers are bidding to claim a new record each day.
The 2024 jackpot slots with the biggest prizes at the time of writing are:
💰 WowPot slots - £35m
💰 Mega Moolah - £8.7m
💰 Jackpot Giant - £6.2m
💰 Dream Drop slots - £2.5m
💰 MegaJackpots slots - £1.1m
💰 Mega Fortune - £0.8m

Tournaments at UK Slot Sites
Slot tournaments are a great way to take your casino gaming to the next level by competing against other players. You’ll play a specific slot to collect the most points or get the highest score.
The idea is to climb the tournament leaderboard and finish as high as possible to win the best prizes. Tournaments are played over a set period, usually daily, weekly, or monthly, with an end time to determine the final positions.
Some tournaments will offer a single prize, while others give a range of prizes for the top few placings.
How Do UK Slot Tournaments Work?
Each casino will have its specific rules, but a tournament will typically feature one or more specific slot games. It’s an excellent way for a software provider to promote one of their titles.
Some slot tournaments are free to enter, but some, known as buy-in tournaments, may charge an entry fee. It will typically cost £10 or more to enter a buy-in tournament.
Free tournaments usually award more modest prizes, such as ten or more free spins. Buy-in tournaments offer bigger prizes, such as bonus money or special prizes like trips or merchandise for the winner.
You must finish at the leaderboard’s top to win a slot tournament. How you gain points depends on the tournaments. It can come from landing the biggest wins, your longest win streak, the total money you’ve wagered or even completing specific tasks.
Do Slot Sites Offer Bonuses?
Many sites use online slot bonuses to attract new customers. These bonuses come in different sizes and have different wagering requirements. From what I've seen, it's a good idea to check out a few sites to find the best deals. Here's what to watch out for when you're shopping around.
No Deposit Bonuses
Some sites offer a no deposit bonus on slots when you sign up for a new account. The deal often includes bonus cash or free spins, and you don't need to deposit to get it, only join the casino. It might look something like this:
Get £5 no deposit bonus when you sign up and use code FREE5, or
Claim 10 free spins on Aztec games, no deposit needed
But this kind of bonus is very rare. Only a few slot sites in the UK offer it, and there's usually some wagering involved. Still, it's a great way to try out slot sites that are new to you and their games.
Reload Bonuses
A reload bonus is a deposit incentive and reward aimed at players who have already opened an account with a casino. As an example, a casino might give you a 50% reload bonus up to £200 when you deposit at least £30. This reload bonus is usually awarded as a non-withdrawable amount which must be wagered before it can be withdrawn as cash.
Cashback Bonuses
A casino might also give you a cashback bonus if you deposit a minimum amount but lose bets during a certain period. For example, if you deposit at least £20 but lose all of that in the next seven days, you could get £2 or 10% back once the week is over.
No Bonus Casino is the perfect example. Instead of giving you a welcome bonus, it gives you cashback on all losses, for life.
#ad. 18+. Gamble Responsibly. GambleAware.org. New Customers Only. T&Cs apply. 10% Cash back without wagering the day after if the player loses all the money in the account.
Min deposit £10. Gameplay is monitored.
Free Spins
Some of the best slot sites often offer free spins to players. These can be a bonus for betting a certain amount the previous day or week. It can be a cushion if you lose bets or a large free spins prize that's given over several days.
Loyalty Programmes
The top UK slot sites usually have a loyalty program. Also known as a VIP program, it offers you various perks as a regular player. The rewards can vary, but here's what you can expect:
Lower wagering requirements for bonuses
Personalised trips and experiences
Your personal account manager
Flexibility to use your cash balance online and at land-based casinos.
It's not surprise that these high roller casino bonuses are often seen as the best rewards for loyal players.
Wagering Requirements
Remember, when you get a bonus, there's usually a wagering requirement tied to it. This rule means you have to play through the bonus credits several times before you can cash out. The next step is to figure out how to calculate it. It's pretty easy, really.
Say you have a £10 bonus with a 30x wagering rule. All you need to do is multiply 10 by 30, and you'll know that you have to wager your bonus 300 times (10*30).
You can also use a wagering calculator for this. Check out our slots bonus page to find our own tool that can help you figure out how much you need to wager in no time.
But every now and then, you might get lucky and find a no wagering bonus. If that happens, whatever you win is yours to keep.
Kristina's Wagering Tip
If you're new to wagering requirements, we have a guide that explains what they are and how to work around them. You can find all the details here.
What’s an RNG, and How Do They Affect Games?
A random number generator (RNG) is used to ensure fairness in all online slot games. It’s super intelligent software that produces random numbers every millisecond. These are instantly matched to symbols on the reels, making each spin completely unpredictable and fair.
The UK Gambling Commission (UKGC), which licences online casinos in the UK, rigorously monitors and tests the RNG systems used by slot sites. Independent labs also audit the RNGs to ensure they aren't biased. Online casinos display certifications in their footer to prove their games meet strict and fair play standards.
Despite this, many myths persist about RNGs and how they work. For example, casino players might still believe that slot games are either running hot or cold. This leads some gamblers to start chasing winning streaks and take unnecessary risks.
In reality, every spin is entirely independent of the previous or next one. Factors like time of day or betting size have absolutely no influence on the outcome of your spins. Ultimately, there’s no secret strategy to beat the RNG, and it’s all down to pure luck!
Payouts and RTP
When you're playing on slot sites, it's important to know about the Return to Player (RTP) percentage. This percentage tells you how much money you can expect to get back from a slot over a prolonged period.
It essentially refers to the house edge. If a slot has an RTP of 94.75%, the average house claim will be £94.75 for every £100 staked.
However, slots are games of chance, and while some players make a profit, others lose. That’s just how it goes.
The RTP gives you an idea of the average return you can expect. So, aim for as high an RTP as possible.
Most games usually have an RTP of around 95% - 96%, but there are exceptions. Take NetEnt’s Mega Joker, for example, with a whopping RTP of up to 99%. Jackpot 6000 is also impressive, going up to 98.8%. These games are among the best-paying ones you can find online in the UK.
It may not always state the RTP rate, but it will tell you what each symbol pays when you match them on a payline. For example, if you see a symbol that pays 100 times for 3 matches, you could win 100 times the size of your bet.
Game developers usually list the minimum and maximum prizes you can win during the base game and bonus round. This info can help you figure out your potential payouts.

Online slot sites with a UK Gambling Commission licence are not permitted to offer credit cards as payment methods.

The payout rate of any casino depends on the Return to Player (RTP) percentages of its games library. Our experts have found that Neptune Play Casino (98.97%) and Virgin Games (97.83%) are top percentage-wise in the UK. That said, RTP is a theoretical calculation and does not guarantee winning.
