As well as which ones take care of their existing clients through loyalty and VIP programs. And the good news is, lots of casinos offer specific bonuses for slots players. The best casino slots sites want you to play with them, so it’s in their interest to entice you with some fantastic bonus offers.
These bonuses could be free cash to play UK slots online with, or even free spins. As with any bonus, always check the T&Cs attached, as there will be some wagering requirements and other rules.
Things to think about when selecting an online slots casino
So, now you know what our casino experts look for in the best slot sites UK. But what should you consider when selecting a casino site? And how do you know which are the best sites for winning? Let’s look at some things you should think about:
- The slots bonus offer: this is the type of bonus a casino is offering you. If it’s a no deposit bonus, this means that the casino will give you free money to play with. This is great because you have no risk whatsoever. And can win without spending any of your own money. Or the bonus could be free spins, which will give you free rounds on a specific game – these can be deposit based or completely free! Finally, also look out for other bonus offers for playing regularly. These could be deposit bonuses, as well as loyalty and VIP programs.
- Terms and conditions: According to a 2017 survey by Deloitte, more than 90% of people accept legal terms without reading them. Before playing with any slot site, always check the T&Cs. This is especially important when looking at bonus offers. All bonuses will come with rules. And these may include restrictions as to which games you can play, as well as wagering requirements and prize limits
- Wagering requirements: these refer to the amount of times you must play through your bonus before you can claim any winnings. For example, if you see that a bonus has x30, this means that you will have to wager your bonus amount 30 times before cashing out. Always check the requirements before playing any slots, to see how you can win. A way to avoid this, is to play at a casino with no wagering requirements.
Different types of slot machines
One of the best things about slots is how many different types there are. While there are thousands of different games available, most of them fall into the following 6 categories. So, let’s take a better look at them in a little more detail:
3 Reel Slots
The classic slot game format. Going back decades, the first 3 reel slot machine games paid out in chewing gum. Hence the pictures of fruit on the reels. Fast forward a few years and slot machines now pay out in cash. And things like cool graphics and music make online slots far more exciting to play.
3 reel slots are a great place to start if you’re new to slot games UK. Because they only have 3 reels, you can track the symbols more easily and learn how to play. Even though they’re considered the more basic version, 3 reel slots are still super fun to play and online casino sites offer over hundreds of versions of this classic game.
5 Reel Slots
Exactly as the name suggests! This is now the most common, and most popular, format for slot games. 5 reel slot machine games give you more ways to win, as there are more paylines. With today’s high-tech slot games, payline combos can reach into the thousands, with different combinations bringing you more winnings.
A typical 5 reel slot will have 5 reels with 3 to 4 symbols on show. Meaning that you can have a grid of either 3×5 or 4×5 to play with. And this will generate between 10 to 50 paylines (where the symbols match to give you a prize), from left to right across the reels.
However, with tech moving fast, and a high demand for more chances to win, developers have increased the paylines to include right to left, as well as diagonal and other combos. This means that, although there are still only 5 reels, there can be many more paylines. A good example of this is the Megaways slot machines from Big Time Gaming, with 117 649 paylines!
You can now find casino sites that offer 6 and 7 reel slots, but the classic 5 reel slot game remains the most popular.
High Payout Slots
When you play casino slots online, you want to win. It’s as simple as that! A small number of lucky people have had their lives changed by huge jackpot wins on casino slots. And, with a bit of research and some know-how, you can set yourself up for a win by choosing some slot games over others.
For example, a good thing to look for when selecting a slot game to play is the return-to-player (RTP) number. This refers to the amount a casino expect players to get back over a certain period of playing the same game. Most slots games will have their RTP clearly displayed, and the higher the RTP, the more likely you are to win overall.
If a game has, say, an RTP of 85%, this means that the slot machine will pay back 85 pence for every £1 that is played on average. And most slots now come with an RTP of over 95%, so you can see how that will affect your chances of winning.
However, RTP isn’t the only thing to look for. You can also search for high or low ‘volatility’. This refers to how volatile the game is – meaning, how likely it is to pay out. Low volatility games will pay out often, but usually in lower amounts. By contrast, high volatility games won’t pay out as often, but the prizes can be huge.
Low volatility games are better to play if you love slots but don’t want to risk a lot of money. But, as they say, you’ve got to be in it to win it! So, high volatility games, although more costly and riskier, will offer you the opportunity to win a massive cash prize.
Fruit machine slots
If you’ve ever stepped foot inside a UK pub, you’ll have seen a classic fruit machine. These staples of British pub life were big, bright and noisy – and so much fun to play! And now you can find fruit machines online at a casino site.
Traditionally, ‘fruities’ follow the 3 reel format, and give you ‘nudges’ and ‘holds’. This simple design has never gone out of fashion. Hence why you can now find them online.
Fruit machine games tend to be of a low volatility. Meaning they pay out often, but the cash prizes will be quite low compared to high volatility games. They’re a great option if you love a bit of nostalgia and lots of chances to win.
With software providers bringing out new games every month, and slots being the most popular casino game around, customers are demanding more and more from their gambling experience. Enter the video slot machine!
Without the limitations of having to build a physical machine, software companies are able to create every type of game imaginable. You’ll find the classic 3 and 5 reel designs, as well as crazy, inventive and downright ludicrous games on the market. There really is no limit to what they can produce, and the most popular types of video slot machines range from Hollywood movie themes, to fantasy adventures through space. Incredible!
Finally we come to the most cutting-edge slots out there. 3D slot machines are an immersive experience for people who adore slots. From the best graphics, to brilliant animations and bonus features, these slot games are the ultimate in slot game magic. Some even come with storylines and characters, so you can get lost in a magical world, as well as win huge cash prizes.
We think that 3D slots are only going to get more popular. So, always check our lists of trusted and reviewed operators, to see which casinos are offering the newest and best 3D slot games.
Payout rates for slots
Slots are purely luck-based games and there is very little that you can do to influence the outcome. Many players like to believe that they can tell when a game is about to pay out. But the truth is that every spin is completely random and you never really know what is going to happen.
Some spins will produce a win while others will not. And this is the very simple nature of these games. The payouts are checked by a 3rd party tester. And they are in turn regulated by the UK Gambling Commission. It is done to ensure that no casino can produce a game without a fair payout structure.
However, there are two ways in which we can study the potential payout of a slot. They will not tell you exactly when you will win or lose. But they can give you an idea of the type of experience you should expect.
What is volatility?
The volatility of a game determines the size and frequency of payouts. This is used to show a player if a game is a regular payer with small wins or alternatively one that pays out infrequently with big wins.
High volatility on a game is often the reserve of a slot with large cash prizes. If you can hit a huge jackpot on a slot, then it is likely that this game will be high volatility. But while you are waiting for a big prize to land, you will not see much action. Your bankroll can take quite a hit in between big wins with games like these.
Medium volatility will give you regular wins of a small to medium value. There will still be some big prizes on offer but you won’t see them very regularly.
A low volatility game will pay out very small wins very frequently. But there won’t be many big prizes to speak of. Some players love this kind of game as their balance will stay intact for a long time.
What is RTP?
The return to player figure is one that many slot fans like to check out before choosing a new game. It shows the difference between the money that goes into a slot compared to the money that comes out of it. It does not tell you how much you will win but rather how much the game will pay back over an extended duration.
Most UK online slots will have an RTP of around 96%. This is widely regarded as the industry average. However, a game with a 94% RTP, for example, will not necessarily be a bad game to play. This figure is in place to show the industry regulator that the game will only keep a small percentage of its income as a profit for the casino.

Free slots vs real money slots
Before you play slots for real money, it’s always a good idea to see how the game works first. There are loads of different features and bonus games embedded into modern slots, which can be confusing. These extras can mean the chance of big prizes but to the untrained eye, it’s very hard to see what’s happening to your money!
No deposit slots
One way to get a good idea of the layout and functionality is to try a demo version first. Many of the casino sites will have a free version that you can play around with until you feel confident about how it works. You will see how to change the stake amounts, how many win lines there are, the bonus rounds available, and any in-play features that occur. However, you need to remember that it’s not real money and a big win on the demo slots can be an anti-climax. But, if you enjoy the game, then you can move on and play the real-money version.
Slots with real money
So now you’ve tried out the demo, you’ll want to get your teeth into the real thing. Slots can be great fun, and may even payout out a good deal of cash. But you must bear in mind that this won’t happen all the time. Online casinos are packed full of hundreds of incredible slots so it can be hard to decide which one you want to play.
To make this decision, you’ll want to focus on a few key areas:
- How much do you want to spend? Some slots have smaller limits than others. If you’re a high roller, then choose a slot that lets you spend freely
- Themes are important: slots come in many shapes and sizes and the graphics and sounds vary a lot. If you have a specific taste, then there’s bound to be a slot to suit you
- Bonus rounds: some games have been designed to be simple and clutter-free. These are great for those who simply want a few reels in play and nothing else to distract them. Although if you like things a bit more frenetic, then these basic machines might not float your boat. Choose a slot that will hold your attention while playing
Slots bonuses explained
There are so many great bonuses out there that it can be hard to keep up. The lure of the various deals all seem tempting, but you want to choose the one that’s right for you. Here’s a break-down of the most popular casino bonuses that you are likely to come across.
Welcome bonus or sign up bonus
Perhaps the most standard offer that you can find today is the welcome bonus. When you sign up to a casino site, they will probably offer to match your first deposit up to a certain amount. In the UK, this amount will likely be a couple of hundred pounds.
After completing the registration and making a deposit, they will release the bonus amount. However, this isn’t yours to keep just yet! You’ll usually need to wager 20-50 times before keeping the winnings that you generate.
Getting a good deal is important. The best best slot sites for winning are usually the ones that give out the most beneficial bonuses.
No deposit free spins
These are the holy grail for slots fans. Some sites will release an offer where you simply need to sign up and register your details. After that, they will gift you a number of free spins to play. But check the small print as they may only be valid to spend on a specific slot. Either way, this type of bonus is great for getting started at a new casinos 2023. Moreover, it won’t cost you a penny to try out some new games.
Deposit bonus + free spins
Perhaps you’re looking for a little bit of everything in a bonus. Smart move! Why restrict yourself to one or the other when you can have both. Deposit bonuses and free spins are frequently on offer at the top gambling sites. You will have to complete the signup process, which is pretty standard and then make a deposit. In return, you get your deposit matched up to a specific figure plus some free spins for good measure. This is an awesome bonus combo, and we have some up for grabs right here.
Casino reload bonus
Sometimes a casino will reward you for simply being a valued customer. Is always nice when a company recognises you, and the best gambling sites will happily do the same. The reload bonus is very similar to a deposit welcome bonus in that the casino will offer to match your next deposit. It may not be a 100% match as the signup bonus tends to be; it might be 50%, for example. You might assume that this type of offer would only show up for VIPs, but that’s not the case. Many casinos will have fixed days when reload bonuses are offered, so keep your eyes peeled!
Slot specific bonuses
Pretty much every slot has it’s bonuses and features. Although some may be deliberately basic in their design, the vast majority have loads of ways to get your hands on some extra cash. Each game is different, but one thing that most have in common is a bonus round. You can often access these by rolling in 3 special symbols. You can win some amazing prizes on a bonus round although the size of the bonus prize will be relative to the stake amount that you’re playing. Among others, you might also find prize drops, nudges and wild symbols.
How to get a good slots bonus
If you’re a big slots fan, then it makes sense that you want to make the most of any online casino slots bonuses on offer. The best way to discover the latest deals is to keep yourself in the know. And you can do that by stopping by our site regularly to see what’s up for grabs. We love a gamble on the slots as well, so we’re always on the lookout for offers. Slots bonuses can be released daily, so be vigilant if you want to be the first to get in on the action. Opting into the casino newsletter is always a great option if you want to hear about these promos.
Here are a couple of different ways in which you can ensure a top bonus when you sign up for a new account.
Don’t just go for any bonus – compare!
The first piece of priceless advice is to resist the urge to accept the first bonus that you see. Sometimes, you may come across a huge potential bonus and automatically think that this is the one for you. However, you need to consider any restrictions that are placed on that promotion.
Every casino bonus will present an opportunity to enjoy some spins or cash. But this regularly comes with wagering and perhaps max cashout rules. By checking out the details of each and every offer, you can make sure that you land yourself the very best deal for you and your cash.
Low or no wagering slots sites
And of course, there are some casinos that simply love to lower the wagering requirements. They don’t do this as a promotion but it’s just part of their regular marketing strategy. Any bonuses that you receive at a casino of this type will only be subject to perhaps 1 to 5x wagering. And even if you are only receiving a small bonus from this site it may well prove to be more valuable than others.
A small value bonus with the tiny wagering requirement is often easier to take advantage of than one that is the complete opposite. As a player, you want to ensure that you get the most bang for your buck. And playing at a low wagering site or even a no wagering one can prove to be a very savvy decision.
Popular slots game developers
There are some fantastic slot developers working in this niche. Many of them produce not only slots but a number of classic games as well. And there are others that produce an entire casino set-up including backroom software and live casino production as well.
When the industry first started in the mid-nineties there were very few companies competing. But now there are many smaller studios that are all capable of producing some of the world’s best titles. And many of them are quickly bought up by the bigger companies.
Let’s take a quick look at a few of the best-known game producers working in the industry.
NetEnt’s one of the best-known game providers on the planet. They began in Sweden providing table games at a range of hotels. But over time, their operations moved to the online sector. This provided them with a massive growth opportunity. And they never look back.
These guys are responsible for producing some of the biggest progressive jackpot games along with some of the finest regular slots that you can lay your hands on. They are now part of the enormous Evolution gaming group which adds live casino to the list of offerings. They are truly a force to be reckoned with.
If you are looking for the original contributor to the industry, then look no further. Microgaming has been there from the first day and many people believe they invented the entire niche. It is difficult to pinpoint an exact time when online gambling became available. But these guys were definitely there or thereabouts. They also have a great list of progressive jackpot games and awesome movie theme slots as well.
Playtech was founded back in ‘99 by an Israeli entrepreneur with a big vision. And within 6 years the company was already valued at a phenomenal $950 million. They create fantastic slots and have a huge library of live games too. They have since gone on to buy up many smaller studios that have increased their portfolio at an astonishing rate. You may well have played some of the games in their Age of Gods series.
Another Swedish great that has been around for many years. Since ‘97, this company has treated us to some of the best titles in the industry. In 2020, they produced an incredible 52 slots, making them one of the fastest growing providers in this niche. They also have a top selection of mobile-optimised games as well.
This is a company that was founded in 2013 by a former NetEnt executive. And they are one of the hottest providers around at the moment. They produce some amazing looking slots as well as some classic casino games too.
Some of the most popular games provided by Yggdrasil are Vikings Go Berzerk, Holmes and the Stolen Stones and Rainbow Ryan.
This is the mammoth of the live casino industry. And they are a relative newcomer to the online slots sector too. Over the years, they have managed to produce some of the best games in both categories.
Evolution gaming was founded in 2006 by a group of Swedish entrepreneurs. They started off life as a small live casino provider. But they quickly rose to prominence and are now the biggest name in the industry.
They have since diversified their operations and now provide an impressive range of slots as well.
This is another Swedish company that has been around since 2011. They were bought out by Playtech in 2016 but continue to operate as an independent studio. And they produce some brilliant slots games.
Some o the most popular titles provided by Quickspin are Second Strike, Sevens High and Spinions Beach Party.
Strategy for online slots players
The best strategy to adopt as an online slot player is one that maintains your budget while you wait for a big payout to come your way. As you know, some games don’t pay out regularly so it is your job to place suitable wagers to keep everything ticking over.
While spinning the reels, there is not much you can influence. So there isn’t really a strategy to adopt in that respect. Game results are random and you just have to hope for the best!
Popular slots features
Modern-day slots are very popular and not just because the graphics and sound effects are so fantastic. It has a lot to do with the winning potential due to the game mechanics and bonus features. There are a few features that are well-loved within the industry and we’re going to take a quick look at some of those right now.
Bonus games are where every player wants to be. Base games can give you some incredible wins but they do have a tendency to be a little repetitive. A bonus game not only breaks up this repetition but also offers some fantastic cash prizes as well. Bonuses can hand out random wins as well as offer you the chance to play a separate challenge that can be very profitable.
In-game free spins
Free spins were one of the first bonus features available in online slots real money. They usually appear thanks to scatter symbols that land randomly along the reels. When you enter a free spins game, you will be allocated a number of spins to play and they obviously do not cost you a penny. There may also be a multiplier attached to any wins. There is no guarantee, but these spins are usually very valuable.
You may also find some other special symbols that land from time to time during a slot game. These symbols can produce random wins, add to progressive jackpots or they may even act as a wild symbol. Wild symbols will substitute for all of the others and can help connect top wins throughout the game. Always check out the game details before you play. This way you know what symbols to expect during the game.
Online slots sites with progressive jackpots
Some of the best online slots UK will produce an incredible amount of prize money. And others go one step further and make it eye-watering. Progressive prizes take a tiny amount of money from every player as they are enjoying the slot action and add it to a central pot. And this prize can be won by anybody at random.
By collecting the money over one or more slot games and various casino sites, this prize can increase to a life-changing sum. Multi Million-pound payouts have occurred on some of the world’s top progressive titles.
Mobile slots casino sites
If you love playing the very latest slot titles, then you may well want to play them while on the go. New slots UK are as fantastic on mobile devices as they are on big screen laptops and PCs, for example. There are a couple of different ways that you can enjoy this action.
The first is to play directly through your browser. You simply type in the web address of the casino and off you go. The website will be optimised to respond perfectly to your screen size.
The alternative is to download a dedicated casino app from your favourite site. This way, you simply need to click on the icon on your phone. You will be taken directly to the action without any delay. And all your account details are already stored and waiting for you to play. This way you will always have quick access to your best casino UK.
How slots tournaments work
Slot tournaments are great for players who love to squeeze in as much slot action as possible. The casino will notify players of an upcoming event via the promo page or its newsletter. So get yourself signed up now if you haven’t already done so.
The tournament will usually have a very simple premise. Each player has an equal amount of credits and a set amount of time to spend them. You need to spin those reels as quickly as possible and hope you win more than everybody else. It’s an incredibly fast-paced way to enjoy all the slots entertainment that your heart desires.
What are the rules for slots?
Casino slots UK are incredibly simple and have very few rules. Most machines will have a maximum amount that can be one during any session. And this is usually set by the casino but will run into tens if not hundreds of thousands of pounds. So no need to panic on that front!
You will need to choose your own wagers. And this normally runs from a few pence all the way up to £100+, for example. And occasionally you will also have the option of selecting the number of win lines that you wish to use. Although many titles have an automatic maximum number of lines selected as standard. You cannot bet more than you have in your balance and this is probably the main rule that you need to remember.
How slots became the most popular casino game
Most players will have fun memories of fruit machines in pubs and bars up and down the country. And you may even remember them from the casino floor. They were always incredibly popular. So it is no surprise that they ended up online. And from there that popularity grew exponentially.
Games of chance have always intrigued the human race. We love nothing more than to have a little flutter and wait with bated breath to see what happens. And slots don’t have to cost you a fortune either. But there is always the possibility of winning some fantastic prizes.
It’s one of the easiest games to learn
In terms of learning curve slot games have one of the steepest. The very first time you spin the reels, you may not have a clue what is going on. But you very quickly learn exactly how the game functions. And it won’t be long before you’re enjoying every second of it knowing exactly what is going on before your eyes.
Even old fruit machines used to cause some confusion with nudges and bonus games. But with an online game, there is very little interaction from the player. So it is an incredibly simple concept to grasp.
Offers a quick-paced thrilling experience
The excitement of a slot is truly fantastic. There is a possibility of spinning those reels many times every minute. And this means that you get to experience the excitement all over again in quick succession. There is often a fast-paced soundtrack that builds the energy along the way and plenty of bright lights to keep you on the edge of your seat.
How online slots have evolved over the years
Online slots have come a long way since the mid-90s. They started as a very rudimentary design with few reels and winning options. The standard three reels and three rows set up soon expanded to five reels and now you can find games with many more rows than you ever imagined. Colossal reels from SG Digital is just one example of how loads of rows can be incorporated into one game.
In the last few years, movies, TV shows, game shows and many more themes have made their way into the niche. And now, game producers are able to create pretty much anything to keep the public happy. Bonuses and features have also become unrecognisable from what they were. There are so many clever little additions to these games that make them a lot of fun to play.
Responsible gaming on slots
Regardless of your budget, you should always make sure that you play slots responsibly. They can be a lot of fun but you should experience this in moderation. Gambling in general can be a great hobby but as long as you keep it in check.
Set up a strict budget and stick to it
One of the easiest things you can do to control the financial side of gambling is to set a budget. Knowing exactly how much you can afford to spare each month is key. Obviously, you hope that you will win but you need to be prepared to lose it as well. And if you only play with money that you can spare, then you won’t have any problems with over-spending.
All of the best online casinos UK will offer players self exclusion of they think they gamble too much.
Don’t lose track of time
When you’re enjoying a great slot session it’s important that you set yourself some time limits. Playing for hours on end without a break is no good for your eyes or your bankroll. Walking away from the game regularly will give you a chance to re-evaluate and play more effectively.
You should treat your gambling activity as you would any other hobby. And this means doing it in moderation. Set aside maybe half an hour, for example, to enjoy the slot action and then schedule in something else.
Small stakes make the game last longer
Many of today’s modern slot games have an incredible range of wagering options. It is possible to play for 10p or even a few hundred pounds sometimes. But if you have a low to medium budget, then there is no point in blowing it all on one or two spins.
Playing with smaller wagers will allow you to enjoy the action for longer. And remember, wins are always relative to how much you put in. So you can still enjoy some fantastic payouts regardless of the cost of your bet.
Make sure the slot site you’re playing at is UK licensed
For players accessing slot fun from the UK, it is important to only play at a site with a UK licence. The UKGC issues all valid licences in this jurisdiction and your casino needs to display the number on their website. You can check out these details at the bottom of the casino’s homepage. If you would like extra security, you can always check this number against the UKGC register.
