Online slots are some of the most popular casino games, both in real-life and at Internet casinos too. There are thousands of online slots available to play in the UK, all developed by well-known and reputable game developers. If you’re a first-timer or are looking to discover new slot machines or those with the best payouts, you’ve come to the right place!
Online slots are online versions of traditional slot machines which generally follow the same rules. You need to spin several reels to match two or more identical symbols on a single spin and active payline to make wins. You bet on each spin and the higher your bet, the more you’re likely to win when making a combination, but this will depend on the individual slot.
Now, it’s important to note that each slot will have a varying number of paylines, which, as explained by 777 Casino1, are lines that stretch across the slot’s reels in different directions. You’ll have to land matching symbols on these paylines to make wins, so the more paylines, the better chance you have of making wins. However, there are some slots which use different systems such as a cluster mechanic where you must make clusters of matching symbols for wins.
In addition, online slots in the UK all use a random number generator (RNG)2 to determine the outcome of each spin of the slots, which means they cannot be rigged and you cannot determine when you’ll make wins. Alongside RNG, all online slots have an RTP (Return to Player Rate) which determines how much of all wagered money over a long period of time and many users is returned to the player.
All online slots are based on themes, and its symbols will usually revolve around said theme. In addition, online slots will usually always some a combination of the below symbols:
While most slots will use the above symbols in the manner explained, it’s important to read through the paytable and rules as some games may change the way these symbols work. In addition, some online slots in the UK also include other symbols which can act as multipliers or other features.
When it comes to online slots, there are different types of games. There are main online slots which are usually based on unique themes, and there are also branded slots and jackpot slots.
Branded slots are online slots that are based on existing properties such as films, television shows, video games, musicians, and celebrities. These online slots will have their entire design based on the brand, and we’ve found that some online slots based on musicians will even feature their music, which can help make the slot even more fun to play! Most game developers do not make branded content but studios such as Play’n GO and NetEnt have released lots of branded slots.3
Jackpot slots, meanwhile, are online slots which offer chances to win either one large jackpot or several jackpots of varying size. There are different types of jackpot slots too, including progressive jackpots which grow in size with every bet made and fixed jackpot slots which feature jackpots of fixed sizes. In addition, some jackpots (Usually progressive jackpots) can be connected to other games or casino sites, meaning that they can grow to giant sizes but can also be harder to win.
The best online slots in the UK are jam-packed with special features, offering you more chances at making wins and making the slot more fun to play. Some of the most common features found in online slots include:
There are notable other special features which can make online slots in the UK more fun, but they’re somewhat rarer. They include avalanche mechanics which can offer lots of wins on single spins, and various wild symbol mechanics such as expanding wilds, stacked wilds, and more.
All of these special features vary depending on the online slot, which is why it’s so important to read through the game’s paytable and rules, so you know exactly what’s available and how everything works.

One of the benefits of playing online slots is that they are compatible with bonuses. There are two main types of an online slots bonus; free spins and bonus funds. Both of these promotions, which require deposits of real money, are compatible with slots but it’s important to note that while bonus funds can be used with all slots, free spins from a bonus are usually limited to select games.
There are other limitations imposed on online slots bonuses like this, including maximum bet size, expiry dates, wagering requirements (Meaning, the number of times you’ll need to wager something before it can be withdrawn), and sometimes maximum win or withdrawal limits. All of these limitations can be found in the terms and conditions of an online slots bonus so you can easily read up on what is expected or required of you.
Alongside the above online slots bonus offers, there are other promotions which are compatible with online slots, and they include wager-free bonuses which do not have wagering requirements, online slots no deposit bonuses, and slot tournaments too.
An online slots no deposit bonus is a special type of promotion which offers you either bonus funds or free spins without you having to make a deposit. To claim these online slots bonuses, you usually just have to sign up with the website and claim them. However, online slots no deposit bonuses tend to have stricter terms and conditions including shorter expiry times, lower maximum win limits, higher wagering requirements, and they can only be used on very select games.
Alongside online slots with no deposit bonuses, another popular type of promotion are online slots tournaments which are competitions where you play specific online slots against other players and try to top a leaderboard to win exclusive prizes. Some online casinos offer these regularly while others offer them as rare promotions. Regardless, you’ll usually have to purchase tickets to enter slot tournaments and will have a select number of spins to use to rank up points for the leaderboard.

However, we suggest you try different online slots out to discover which mechanics you prefer, what kind of gameplay you enjoy, and so on. Remember, only you can determine what the best online slots are, and you’ll have to play to find out!
Due to the sheer number of online slots in the UK, it can be difficult finding the best online casino slots, even if you research every game available. Luckily, we’ve spent lots of time reviewing and checking out different slots and have compiled our list of the best online casino slots available right now. Take a look at our recommendations below:
Book Of Dead is one of Play’n GO’s most famous games and one of the best online casino slots around. The Egyptian-themed slot follows adventurer Rich Wilde as he attempts to uncover the ancient Book Of Dead. The game uses a 5x3 layout with 10 paylines, has an RTP of 94.25% and comes jam-packed with plenty of special features including wild symbols, expanding symbols, and a gamble mechanic to boost your winnings.4

Mustang Gold is an online slot by Pragmatic Play, and one of the developer’s most popular video slots. The Wild West-themed slot uses a 5x3 layout with 25 paylines and it has an RTP of 96.53% which is high, making it one of the best online casino slots to play. Special features in this game include a free spins mode, scatter symbols, a pick-an-object mode, and plenty more to help you make wins.6

The slot is also packed with features including an avalanche mechanic, scatter symbols, a bonus wheel, free spins, random wilds, and more.8
Another benefit of playing online slots is that almost all of them are compatible with mobile devices. This means that you can easily play all of your favourite slots on mobile and while on-the-go as long as you have an internet connection. Unfortunately, there will be some online slots that cannot be played on mobile, but there are enough online mobile slots to keep you busy for a very long time.
Generally speaking, there are two ways of playing these online slots on mobile devices; either by downloading a dedicated casino app to your phone or playing online slots at a casino website in your smartphone’s browser. It couldn’t be easier to access and play online slots!
When it comes to playing online slots, there are two main ways; playing online slots with real money and playing for free. In the UK, you cannot play online slots for free, nor can you demo slots. This is due to the tight rules surrounding slots imposed by the UK Gambling Commission. The main way to play online slots is real money, meaning you’ll need to use real money to play online slots.
One way around this limitation, however, is by registering with a casino site offering a no deposit bonus, essentially allowing you to play for free. Unfortunately, it can be extremely hard to find a casino website offering no deposit bonuses, so most gamers just play online slots with real money anyway.
As we’ve already mentioned on this page, all online slots have varying RTPs, and it’s a good idea to try and find a video slot which has a high RTP to provide you with a better chance at making wins. We’ve reviewed countless slots and have decided to put together a list of slots with the highest RTP rates so you can easily find the best paying online slots and start playing.
The answer to this question will generally depend on your personal preference. Many people enjoy playing online slots because they are simple to understand and learn but can offer big wins and be extremely exciting to play. Other users, however, prefer playing online versions of classic casino games like poker, roulette, blackjack, and more.
You can also enjoy playing all of those games too. If you’re unsure about what type of game you might prefer, we suggest you try playing different casino games to figure out what entertains you the most. So go ahead and try, you might find that you’re a big slot lover or someone who just prefers other casino games!
Playing online slots is easy. Generally speaking, all you have to do is find an online casino offering the online slots you want to play and then register with it and verify your account. Once you’ve done this, you can make a deposit, claim any associated bonuses, and then open up the online slot you want to play.
Once you’ve loaded up the online slot, you’ll need to adjust your bet by using the buttons at the bottom of a slot. After adjusting it to your desired size, you simply need to hit the ‘Spin’ button to start the game or use the online slot’s autoplay function, allowing you to select how many times you want the slot’s reels to spin automatically.
Online slots are incredibly fun to play, and they’re widely available in the UK. You shouldn’t have any trouble finding the best online slots, and since there are so many special features, gameplay mechanics, and themes, you’re unlikely to ever get bored. If you’re new to slots, we suggest you check out some of the best online slots we’ve recommended on this page and sign up with some of the casinos here too, and within no time you’ll be playing!
The best way to discover what the best paying online slots are is by heading over to a slot developer’s website and check the RTP rates listed there. However, since there are so many online slots in the UK, this can be rather time-consuming. That’s why we suggest you look through the list on our website which easily provides you with the information you need.
Online mobile slots work just like their desktop and laptop counterparts. As explained, you just need to load up the casino either in-browser or through an app and start playing. Most websites are now compatible with touch devices, so you can easily play while on-the-move.
All you have to do to play online slots with real money is register with an online casino, verify your account, and make a deposit. After that, you’ll simply have to load up your slot and play! It’s that simple!
Unfortunately, due to UK regulation, you cannot play online slots for free. All online slots must be played with real money and you must be a verified and registered user at a licensed casino website.
