Best Online Slots UK

Nearly every week there is a new online slot to try out, whether your choice is classic or video slots. Many large software providers and niche companies are always competing for a piece of the action. So take a look at newest online slots in UK casino sites and give them a go:

UK Slots Sites Guide

Playing slots is easy, but it’s always better to possess some basic knowledge. So before you open an account at one of our best online slot sites and start playing for real money, let’s start with the basics.

The name slots comes from the time when you put a coin in the slot of the physical machine in order to play.
The aim of the game is to match up combinations of symbols to win money.
The online format has given free rein to the software developers to get really creative with the graphics and the gameplay itself. These games have come a long way from the days of the one-armed bandit so popular in casinos and pubs.
If you want to skip the tedious process of redeeming your bonus winnings through wagering requirements, check out our list of no wagering slot sites.

How RNG Works

In order to ensure that the games are completely fair, all online slot games are controlled by a random number generator, or RNG for short. How this actually works requires an advanced degree in mathematics to truly understand, but the result is that each time you hit play, the outcome of that spin is random and unconnected to what has gone on before. This is how players know that there is no possibility that the game is rigged, and that everyone playing has the same chances.

Slot Glossary

Slot games may be simple in principle, but there is a lot of terminology that may be unfamiliar to novice players. Luckily for you, we’ve created this glossary of slot game terms to help you make sense of it all.

Rows and Reels: The reels are the parts of the slot that spin vertically, and in the physical machines they are shaped like wheels. The rows are what you see presented horizontally across the screen when the reels land, and it’s here that you see if you have won or not.
Paylines: A payline is a winning combination of symbols. To understand paylines, it’s easiest to imagine a very basic old-fashioned slot machine. Here there is one payline, which is when you match three symbols horizontally across the centre row. For online slots, there are multiple paylines in different configurations across all the rows. Some slots have hundreds of winning combinations.
Symbols: These are the images that appear on the reels, and they were traditionally fruit-themed which gave rise to the alternative name of fruit machine. These days, the symbols are in keeping with the theme of the slot, and are limited only by the imagination of the game’s creators. As well as the regular symbols, there are some special ones as we explain below. Not all slots have all these symbols, but the good ones will have at least one of them.
Scatters: This is a symbol that triggers some kind of special feature, such as a bonus round or free spins. A scatter does not have to be on a payline to activate the feature, but usually two or more must be on the reels for it to count.
Wilds: Another special symbol that can stand in for any other symbols and create a winning combination – just like a joker in some card games. This is the basic wild, but there are many types. Expanding wilds will spread out and fill a whole reel, sticky wilds will stay in place for multiple spins and shifting wilds will move across the reels on subsequent spins.
Multipliers: Exactly what it sounds like. If you land this symbol in a winning combination, your prize will be multiplied by a set amount.
Bonus: Similar to scatter symbols, a bonus symbol will access a special feature such as a bonus round, a side-game or a bigger payout.

More Slots Terms

Variance: Also known as volatility, this is a quality of a slot game built in at the design level. Variance can be high, medium or low. High variance games pay out less frequently but larger amounts. With a low variance slot, expect smaller payouts but more often.
RTP: This stands for the return-to-player ratio, and is given as a percentage indicating how much return a player is likely to get from the money they put into the machine. So, for a slot with an RTP of 95%, you can expect to walk away with an average of 95% of the money you put in, with the casino taking 5%. Obviously, the higher the RTP the better. It’s important to note that RTP is calculated as an average over a large number of spins, and doesn’t apply to each spin individually.You can find the list of highest payout slots here.
Coin Value and Bet Level: In combination, this determines how much money you are staking on each spin. Coin value is the denomination of each coin, and bet level is how many of these coins you wish to place on each spin and how many paylines you are choosing to play.
Pay Table: All of the terms listed so far will apply differently to each slot game. If you want to know the details of your chosen game, such as what the scatter symbols are or how the paylines are configured, all this information can be found in the pay table. Always familiarise yourself with the pay table before playing a new slot.

Types of Online Slots

Now that we’re up to speed with all the terminology, let’s take a look at some of the different types of slots that you can expect to find when visiting slot sites. The developers of these games are constantly coming up with new twists to make their creations stand out from the crowd, but the vast majority of casino slots UK will fall into one of the following categories.

Three-Reel Classic Slots

Modeled on the original machines, 3-reel slots are straightforward and easy to understand. Three rows, three reels and often only a single payline across the central row. These basic games have fewer features and are less common online, but if you want to play then there are slot sites UK offering a selection of classic slots.

Five-Reel Slots

5-reel slots have two more reels and multiple paylines that go straight, diagonally or zigzag across the rows, offering more opportunities to win. They do take longer to understand than their predecessors, and it’s a must to study the pay table before spinning the reels though.

Progressive Slots

Progressive slots, also known as progressive jackpot slots, are linked together either within one casino or across multiple sites. This means that every player is adding to the jackpot at the same time, and the pooled money adds up to some massive amounts. The chances of hitting the jackpot are low, but many people think it’s worth the risk. It’s usually necessary to bet on every payline to be in with a chance.

Blitz Mode Slots

For those who are a bit impatient, a new blitz mode by Hero Gaming was invented. Instead of seeing the elements in the reels of the slots, the interface is replaced by a circle of pure slots energy that vibrates as spins are executed, making the slot game up to 6x faster. This type of game is available on Starburst, Gonzo’s Guest, Twin Spin, Berryburst, Butterfly Staxx to name a few.

Mobile Slot Sites

Mobile devices are becoming the most popular medium for playing online slots, and so brand new casinos with slot games are designed with mobile users in mind. Mobile slots are completely compatible with phones and tablets, and can be played on iOS, Android and other operating systems. Many older slot games have also been modified so that they are available to mobile users. When it comes to gameplay, mobiles and slots are a match made in heaven.

The layout of a slot is perfect for a mobile screen in landscape mode, and spinning the reels with the touchscreen creates a more realistic and immersive experience for the player.
Mobile slots are super responsive and run seamlessly even on average-specced phones.
The best online slot sites will give you a chance to play directly form your browser.
Otherwise, you will always be able to download their dedicated app.

The Technology Behind Mobile Slot Sites

Mobile slots have truly come into the fore due to HTML5 technology. Thanks to HTML 5:

Game designers can create multi-platform games that cross over from desktop to mobile without losing any of the features or game mechanics that make them special.
The quality of the graphics, sound effects and gameplay remains pitch-perfect;
In many cases the slot game actually plays out better on a mobile device than it does on the desktop.
Mobile slots sites offer hundreds of slot games to avid slot game fans. Some of the older games that were originally designed solely for desktop play have now been upgraded for mobile gaming.

For a greater selection of mobile friendly games, we recommend searching our UK slot sites that are dedicated to mobile slots!

iOS and Android Mobile Slots – What Are the Differences?

Modern casino apps are offered in both iOS and Android formats and can be found in the corresponding app store. All you need to do is download the app to your mobile devices and click install. In the early days of mobile gaming, apps were a great way for online casinos to offer mobile compatible games to their clients.

These apps tended to be a scaled down version of the original desktop version of the casino, but they came with bonuses and features that helped make up for the fact that there weren’t as many games on offer. Now that game designers are utilising HTML5 technology, there are more games available. However, as mobile devices themselves have become more powerful, accessing mobile slots via the desktop is, in our opinion, a better option.

How to Play Free Slots

With so many thousands of slots to choose from, it can take some time to find one that you really like to play. Sure, you can research the themes, read some reviews and pick one, but there’s nothing like playing it for yourself.

If you want to shop around for the right one, you may want to try playing for free so that you don’t spend money on a slot you don’t enjoy. Luckily, there are a couple of ways that you can do this.
The first is to find the game you want to try in demo mode. You can find a number of slot sites UK offering this option, or alternatively some demo versions can be found directly from the website of the game developer.
In demo mode, you will be assigned a very generous amount of play money, and then you can spin the reels and play the game in exactly the same way as you would if you had real money in your bankroll. This gives you time to see all the features of the game without spending a single penny.

Another way is to play with free spins without deposit needed. This is where a casino will give you some bonus money or free spins simply for signing up at the site. They can be a little hard to find, but they are definitely out there. Be aware that if you find a no deposit slots bonus, your choice of which slot to play may be limited to a few selected by the casino.

Free Mobile Slots

If you are still getting to grips with mobile slot sites, it might be a good idea to play free mobile slots before you commit to depositing any real money. You can play free mobile slots without having to sign up for an account at a specific mobile slot site. Playing the games in demo mode will give you a chance to learn the rules of the game properly before you place real money bets and it will also allow you time to get used to the particular mobile slots sites you want to join.

How to Play at Slot Sites

Slots are totally random, so there’s no strategy that you can adopt to improve your chances, right? Well, only partly. While it’s true that there’s no way of controlling where the reels will land, there are some tips that you can follow to get the most out of your game. We can’t promise you a big win, but the following advice will stand you in good stead.

Find slots with high RTP

We explained this term in the glossary, but what counts as a high RTP? 95% might sound high, but there are many slots out there with 97% or more. The only reason we can see to play a low RTP slot is if you really love the theme. Read our guide to the best paying slots on the market today!

Look at the variance

A low variance (AKA volatility) slot will generally allow you to play for longer with your bankroll, so if you’re playing simply for the fun of it then these are the games for you.

Choose your paylines

The more paylines you bet on, the more chances you have of winning per spin. If you choose the lowest coin value and bet on the maximum number of paylines, then your rewards will be smaller but more frequent than if you bet the same on fewer paylines. You’ll also hit the bonus games more often.

Manage your bankroll

This is probably the most important of all. Before you even start playing, set yourself a limit of what you are willing to spend. If you’re unlucky and reach your limit, don’t be tempted to chase your losses. Nowadays, more and more slot sites UK allow you to set daily, weekly or monthly spending limits in your casino account. If this tool is available, we highly recommend using it, as it takes the decision out of your hands. Great for those of us who can resist anything but temptation!

Pick Your Payment Method

The best slot sites will most likely allow you to play your favourite slot games while making deposits and withdrawals with the banking method of your choice. For example, by choosing a PayPal casino, you will have the possibility to play the best paypal slots UK gamblers can enjoy while paying with arguably the safest banking method available right now. If you prefer paying via mobile, on the other hand, you can play at one of the several Boku slot sites available in the UK!

Bonuses You can Find at UK Slot Sites

Today’s slots bring an increased number of pay lines and betting ranges, making some huge wins possible on every spin of the reels. They are very simple to play, but choosing from the myriad of fantastic options can be difficult. It is a good idea to try all the free play slots before playing for real money! We have a full list of current slots bonuses ready for you.

UK Slot Sites – FAQ

How do I choose paylines?

How you choose the paylines depends on the game. Many games have an option to bet on all paylines, or you can select them individually. Some games have fixed paylines, meaning that you have to bet on all of them every time.

How do I know what the paylines are?

All the information you need about the slot, including what winning combinations are available and how many coins each pays out, can be found in the pay table.

How do I find the best slot sites?

The most important thing to look for is the licensing. All slot sites UK must hold a license from an accredited body such as the UK Gambling Commission. Beyond that, it’s a matter of personal taste. Look for a casino with a great selection of slots in the library, and which has a theme that you like. Also look at what bonuses and promotions the casino offers. Many casino sites have regular promotions that will keep you going well beyond the welcome offer, and VIP schemes for loyal customers.

Are slots really random?

In a word, yes. If you’re playing at a licensed and regulated casino, then the slots are controlled by the RNG and the casino cannot interfere with the game. This means that there is no ‘good’ time of day to play, and the odds of winning the jackpot do not increase or decrease the longer you play. It also means that the games are completely fair.

How can I win a progressive jackpot slot?

The chances of winning are pretty slim, but with such a big potential payout it’s hard to resist. Most progressive slots require you to place the maximum bet on each spin to be in with a chance.

What slot themes are available?

Almost anything you can imagine. There are lots of slot games based on famous movie and TV franchises, for example. With so many thousands of slots on the market, you’re bound to find one that suits your tastes.

Are demo mode slots rigged?

Not at all! Some people are suspicious that when a slot is in demo mode, the game has been manipulated to appear more favourable and therefore encourage you to play it with your own money. In reality, free slots in demo mode are controlled by the RNG in exactly the same way as the real money games. The experience is identical – except of course you can’t win any money in demo mode.

What’s with the fruit symbols?

A bit of slots history trivia to end with. The traditional slots symbols are fruit-themed, and in the UK many of us know them as fruit machines. This comes from the very early days when playing such games for money was banned. Instead, the machines would dispense fruit-flavoured gum when you hit a winning combo. The symbols corresponded to the flavour of the gum.

Can I win on Top Free Online Slot Machines?

All the best casino sites in UK will offer video slots and classic slots that can be played for free. You can take advantage of this to have some fun, and although you do not win any money, it is the perfect way to learn how they work or try out new games.

There are some sites that specialise in free play, with others requiring no download and no registration. Even better, there are some casinos which offer a small amount of free bonus cash or free spins. These bonuses not only allow you to play for free, but you can also win real cash! They may require you to register with the casino, but you can then enjoy the best of both worlds.

Should I play online slots?

Slots are renownedly easy to play, being comfortable and simple as well as entertaining at their heart. Slots rules are also easy to follow even for a novice player, albeit differing slightly from game to game. Pay lines run vertically, horizontally, and/or diagonally, with combinations of specific symbols triggering wins.

Each spin played is either a win, a possibility for a bigger win, or a loss. Slots are in many ways the perfect “relaxation” game with little effort required from the player, making room for comfort and entertainment.

How to win when I play slots online?

Though slots are many and varied due to their popularity, the simplicity of the game itself allows for a level of strategic playing. Tips for slots are straightforward and basic. Plan out your stake strategy ahead of time, how much you can afford and for how long you intend to play for.

Remember the “golden rule” of gambling, and quit while you’re ahead; chasing losses procures fewer wins than it collects. Online slots are laden with bonuses, so take advantage of them whenever possible. The best tip, however, is to choose the game that best suits you, after all, playing is supposed to be fun.
