Online slot sites are a popular niche in the gambling world, giving players the chance to play a wide selection of slots in many different styles. From classic 3-reel options to exciting jackpot slots, it is easy to see the appeal. With so many brands out there offering a wide variety of games and the chance to win real money, where do you even start? Our list of the best slot sites in the UK will outline those with the biggest game selection, welcome bonus and many other perks.
There’s so much more to online slot sites than just slot games; in fact, there is a whole load of criteria we use when it comes to compiling our top list. Our experienced team has looked at hundreds of operators over the year. We know what goes into a good site, and at the same time, we know what a bad one looks like. On this page, we share this knowledge and save readers hours.
Every slot site we recommend has a UK Gambling Commission license, meaning they are authorised to operate in the United Kingdom. This regulation level is an absolute must-have, and you won’t find a single brand on this page without it. There are many unlicensed slot sites and scammers out there, so it’s important to be vigilant, and only join one from a trusted source.
You will find a detailed overview of specific slot sites and their pros and cons on this page and an insight into the very best slot games, types, and developers. We are here to help you have more fun, earn extra spins and enjoy your gaming experience.
There are so many UK slot sites that there’s a lot of work involved separating the good from the bad. This processes would take hours for an individual, but luckily, we’ve got a team that has done the hard work for you. You may be wondering exactly what goes into our slot site review criteria, so we are here to explain.
Slot sites for UK players are required to have a license with the UK Gambling Commission. This gives them the right to operate in the country and ensures that they comply with many rules. These include stipulations around fairness and promotions, and the UKGC also works as a mediator between player and operator in the case of a dispute. We also check for encryption, protection of personal data and many other safety aspects.
The first thing we look at in the best UK slot sites is the welcome bonus for new players. This will usually be rewarded upon your first deposit and range from a match bonus to free spins. More often than not, free spins tend to play a part in a welcome bonus, whether alone, or as part of a wider package. We're on the lookout for the biggest rewards and expect 50 bonus spins or above, which is quite standard for slot sites in the UK.
Each site needs to have a wide selection of games, including the very best online slots. We want to see everything from the award-winning huge titles like Book of Dead, Starburst and Age of The Gods, to more niche games across different categories. There should be new games, old games and progressive jackpots from the big software developers like Big Time Gaming, NetEnt and others.
Many of us love to enjoy online slots and some of the appeal of very obvious. They are fun, exciting, and there is a chance of winning some cash. But why should you play slot games online, instead of visiting your local casino? Here are some of the main reasons:
A slot site is available 24 hours a day, 7 days a week, and 365 days a year. Not only can you play whenever you like, but you can enjoy online slots wherever you are too. These games can be enjoyed with the click of a button across any device, and you can be playing in seconds. No waiting around in queues for your turn, log in and go.
One of the biggest appeals to an online slot is its theme. This can be anything from fantasy, like wizards and magic, to Ancient Egypt and the jungle. However, some of the most popular slot games are based on our favourite TV shows and movies. This has been done many times, but some notable titles include Game of Thrones, Ted and Family Guy. You can play alongside familiar characters that feature within the slot and bonus rounds.
There is a misconception that deep pockets and a big bank balance must play online slots, but it simply isn’t true. In fact, you can set your own budget, and choose exactly how much you wish to spend. The minimum and maximum stake will vary across games, but it can be anywhere from 0.10p right up to £20 per spin. These limits will be higher if you are a VIP player.
A slot game can come in many different variations, and most players have their favourite type. New technology is giving us even more choices of fantastic games to play. Below, we have outlined some of the different types of slots and explained the key differences.
The video slot is used to describe the new slot game as we know it. We're talking about the modern and well-designed games that feature multiple bonus rounds, free spins and reel modifiers for even bigger winning combinations. These are the most played across slot sites in the UK, mostly because of their recognisable themes and multiple ways to win.
The king of the online slot, progressive jackpots are the only ones that give players the chance to win staggering amounts of money. These jackpot totals rise quickly, as they are accumulated from stakes across hundreds of slot sites. Any single spin can trigger the jackpot round, but only one very lucky player can land the top prize, which can be over £1 million. The most famous progressive jackpot is, of course, Mega Moolah.
The very first slot designed featured 3 reels and straightforward pay lines. We're talking about the classic fruit machine style game with the famous cherry, 7 and bar symbols. Although they may seem outdated today, they very much still have their place on slot sites. Despite having fewer ways to win than others, the payouts can be just as lucrative, so don't be fooled into thinking they aren't worth playing.
There are new games developed regularly, that wouldn't fall into these specific categories. One of the latest adaptations is Slingo, which is a smart combination of slots and bingo. Combining these two favourites has created a whole new category of its own, and has attracted brand new players to online gaming fun. Instant wins and scratchcards are often placed under the slot variant too, as they differ from the standard casino game.
We all have our preferences for our favourite online slot, but more UK players than any other play some. These include Book of Dead and Rainbow Riches, but there are thousands to choose from. We write reviews of the best online slots, including information about their RTP, volatility, gameplay and more. Check some of them out below.
Online slots sites offer a range of bonuses to UK players, and they differ slightly from casino bonuses. There are two main reasons for this. The first one is that they want to stand out from the competition and attract players to their brand, where welcome bonuses come from. The other reason is to retain players and encourage loyalty to their site. Either way slot sites offer generous promotions to new players and existing ones, and there are some examples below of what these look like.
Perfect for the new player, a first deposit match is exactly that, a bonus on your first deposit. They can differ greatly across sites, but a typical example would be 100% up to £100. These are some of our favourite offers, as they are more flexible than other bonus types. Instead of bonus spins on selected games, these 100 welcome bonus funds can be used however you like, whether you want to play slots or table games. As you might expect, there are terms and conditions, and the main one to be aware of is the wagering requirements. You will not be able to make a cash withdrawal without wagering the total bonus first.
Free spins are a staple of any slot site, and UK players love them. These can range anywhere from 10 spins or above, but the very best online slot sites can 50 free spins, or even 100 free spins to new players. They will often be restricted to specific games, and spins on Starburst seems to be one of the most common offers right now. Remember that any winnings placed in bonus funds and are subject to wagering requirements and other conditions. They must be used within pretty short timeframes, so keep an eye out for that.
Although a first deposit match and free spins are the most common, some other slots can be claimed. Cashback is one of them, where you are rewarded with a percentage of your losses back throughout a specific period. This isn’t just limited to new players either. It’s often used for loyalty rewards and VIP schemes.
There are also some no deposit bonuses out there, but we tend to recommend avoiding these. They come with unrealistic terms and conditions and rules, making it very hard to win from. Although they are a good option for testing out a slot site and playing for fun, don’t expect to walk away with any cash.
We have explained all of the bonus types available at online casinos and slot sites, but one of the most important things to look for is the terms. Don’t worry, though, these are crystal clear throughout our site and on each of our reviews. If you decide to go it alone, always read the conditions of any offer, and pay particular attention to these.
Every online slot has a return to the player percentage or RTP. This is the percentage that the slot pays back of all stakes, so for example, for every £100,000 spent on a slot with an RTP of 98%, £98,000 would be returned. This is an accumulation of all stakes, from all players, and so your personal return could be a lot higher, or a lot lower, than 98%.
So why does this matter? Well, when choosing which online slot to play on, you should always consider the RTP. You have a higher chance of winning with a higher payout slot. The best slot sites have a wide range of games available, all with differing return percentages, which determines their overall payout rates. But realistically, it’s almost impossible to calculate which site is the best for payouts, as so much of it comes down to sheer luck.
Looking for an online slot that pays out more than the others? Well, look no further. Below, we have outlined the highest RTP slots in the UK right now. They may not be the most thrilling of games, but they can be pretty lucrative.
Despite being great for payouts, there is a drawback to these games. You won’t be able to use them when trying to complete wagering requirements for a bonus. Because of their high RTP, they will often be excluded in the terms. This means that you will only be able to play them with real money, but that also means that winnings are in cash.
We’ve talked about wagering a lot on this page, as it is very much part of enjoying online casino and slots. Operators use these rules to minimise how much they lose, as it essentially makes it harder for players to win.
The good news is, it’s possible to find online slot operators that offer significantly lower wagering than the rest. These are becoming incredibly popular with UK players, and there’s no wonder why. If 2 slots sites offer you 100 free spins, one with 35x wagering the total, and the other asking 10x wagering, it’s obvious which you should choose. The best online slots the UK should be enjoyed as freely as possible, with flexible conditions.
There are hundreds of online slot sites out there, so much so that it can be hard to choose the best. Making it even more difficult, new slot sites are opening every month. This is exactly why using a site like ours can save you a whole load of work.
When it comes to welcome offers, the rule is only one bonus offer per player. The good news is that there are plenty of frequent promotions for UK players, and you can get as many as you want. The best way to do this is by joining more than one slot site and signing up for email communications so that you’re made aware of new offers.
If you have a bonus that is subject to wagering, you will need to be clever about which games you play. There’s no way to guarantee a win, but playing a high RTP slot with low volatility will increase your chances. This means that wins are smaller but more frequent, and the overall payout percentage is higher than the average.
Although very similar on the surface, the main difference is the selection of games. Online casinos tend to include a lot of table games and don’t specialise in one particular area. So although you can play slots, there won’t be as big of a choice as on top slot sites. This will also result in a difference between the welcome offers and promotions too.
