Why Trust Our UK Slot Sites Recommendations?
Our UK slot sites recommendations are trustworthy - and reliable - as our team of online gambling experts thoroughly researches and evaluates each site before we include them on our list of recommended sites.
We also regularly update our list to ensure that only the best and most reputable sites are included. Additionally, we only recommend sites licensed and regulated by the UK Gambling Commission, ensuring they are fair and safe for players. All of the popular slot sites you’ll find recommended here have fair terms and conditions for their bonuses and promotions, they (usually) have a customer support team working 24 hours a day, seven days a week, and you are very unlikely to run into any problems when playing at them.
Best Slot Sites: Sign-Up Offers
All of the best UK slot sites offer new-player bonuses and promotions, allowing you to start your online gambling journey with a little extra cash. However, most of the sites recommended on our site also offer a wide variety of ongoing promotions. This means that it’s not just new players who are catered for! Below, we will walk you through some of the most common bonuses and promotions you’ll find at UK slots sites.
Welcome Bonus
Every slot site on the planet offers a welcome bonus to new players. These welcome bonuses are designed to attract new players, and, as a result, they’re usually pretty generous. A welcome bonus usually comes in the form of a match deposit bonus. This means the casino will match a percentage of the player's first deposit.
Most online casinos in the UK offer a 100% matched deposit bonus. Say, for example, you make a deposit of £100. The casino would then credit your online casino account with an additional £100 to play with, bringing your total account balance to £200. Welcome bonuses can vary greatly in terms of the amount offered and the terms and conditions attached to them - and we always look at the wagering requirements and “hidden” terms to make sure they’re fair - and that you stand a good chance of actually cashing out!
Deposit Bonus
A deposit bonus is pretty similar to a welcome bonus - but unlike welcome bonuses, which can sometimes be awarded without you needing to make a deposit, a deposit bonus requires you to put money into your online casino account. Again, deposit bonuses are usually matched deposit bonuses - meaning the casino will “match” your deposit by a certain percentage.
New players usually benefit from 100% matched deposit bonuses, but when online casinos offer existing players deposit bonuses, they’re often worth 50%.For example, a 50% match deposit bonus on a £100 deposit would give the player an additional £50 to play with, for a total of £150.
Free Spins Bonuses
Free spins are a major part of almost any slot site - and this type of promotion allows you to spin the reels of a slot without spending any money. Free spins can be awarded as part of a welcome bonus or as a standalone promotion. For example, some online casinos will partner with game developers to give their players free spins when a new game is released.
Some of the best slots sites in the UK now offer wager-free free spins, too. This means that any winnings from the free spins are free from wagering requirements, so you can withdraw them immediately!
Free Spins No Deposit Bonus Offers
Although no-deposit free spins bonuses are becoming more difficult to find, they still exist - if you know where to look. A no-deposit free spins bonus is a popular offer at some online casinos, allowing players to spin the reels of a slot game for free without having to make a deposit.
As you might expect, no deposit free spins bonuses usually come with quite strict terms and conditions, as casinos cannot afford to give away free money easily. For instance, there are often high wagering requirements and a maximum cashout limit. Nonetheless, we all love getting something for nothing - and no deposit free spins are an excellent way to try out a new casino without risking your own money!
No Wagering Slots Bonuses
Again, just like no-deposit free spins, no-wagering bonuses are becoming harder to find, as UK casinos face financial uncertainties due to a range of new regulations from the UKGC. However, they are still available - again, if you know where to look.
So, what is a no-wagering bonus? A no-wagering bonus is a promotion offered by some online casinos that allows players to receive a bonus and keep their winnings without meeting any wagering requirements! The terms and conditions for no-wagering slots bonuses can vary significantly - but you’re usually free to withdraw your winnings immediately, or use the funds to play other games.
Best Slot Sites: Different Types of Casino/Slots Software
In the past, many online casinos were powered exclusively by one software provider. However, over the last ten years or so, online casinos have realised that players want access to as many games as possible, and this means that the best slots sites now offer thousands of games from a wide range of game developers. Below, we’ll look at a few of the biggest names in the slot development world.
Games Global (Formerly Known as Microgaming)
Microgaming is one of the oldest and most reputable iGaming developers on the planet. Founded in 1994, it is well-known for developing the first online casino software, as well as one of the world’s first online poker clients and live dealer casinos.
Microgaming is known for its video slots, and some of its popular titles include Immortal Romance, Thunderstruck II, and its world-famous progressive jackpot game, Mega Moolah.
Netent
Netent is another of the major players in the online gambling world. This Swedish-based software provider is behind some of the most successful games on the planet, including Gonzo’s Quest, Starburst, and Jack and the Beanstalk. Netent used to operate a live dealer casino, although this has now been retired. Virtually every UK slot site will offer games from Netent - and they’re always great fun to play.
Play’n Go
Play’n Go is another Swedish company known for its high-quality mobile slots. They haven’t seen as much success with casino table games, but their video slots are world-class, and include popular titles such as Book of Dead, Reactoonz, and Wild Frames.
Pragmatic Play
One of the newer game developers on this list, Pragmatic Play has enjoyed a rapid rise to fame; over the past few years, their games have become some of the most popular in the online gambling industry, and they’re well-known for their innovative and engaging slot mechanics. They’ve also recently launched “Pragmatic Play Live”, offering a full suite of live dealer games.
Nolimit City
NoLimit City is another pretty new name in the online gambling world - and like Pragmatic, they’ve also seen rapid growth in the last couple of years. Known for producing ultra high-variance games, Nolimit City’s games often boast payout potentials of thousands of times your stake - and their games are widely available at most UK slot sites.
IGT
IGT is the oldest game developer on this list, and they actually started by developing slot machines for land-based casinos in the USA. While their online video slots haven’t caught on as well, they still have some iconic titles behind them, including The 100,000 Pyramid, Family Guy, and Siberian Storm.
Best Slot Sites For Winning
If you’re interested in finding the best slot sites for winning, there are several factors you should take into account. Firstly, you should always try to play games with a high RTP. RTP - the return to player percentage - determines the amount of money that a video slot is expected to payout over its life. For example, if you have a slot with an RTP of 97%, it means that - on average - for every £100 you spin through it, you’ll receive £97 back; the casino would make a profit of £3.
Variance is another factor to consider; high variance games offer the biggest wins, but bonuses and features are usually harder to trigger. Low variance games, on the other hand, pay frequent wins - but they’re not usually worth much, so it’s all about finding what you like!
Best Mobile Slot Sites
Today, almost every UK slot site is mobile-optimised; this means you can simply open up your mobile device’s internet browser and begin playing without downloading or installing any software. However, some of the bigger slots sites also offer a downloadable mobile casino app. These apps are free, and can be found in all major app stores.
The best mobile slot sites offer their full game range on mobile devices, let you contact the customer support team from your internet browser, and make it easy to navigate the site. All of the online casinos we recommend are fully mobile-optimised, so you'll have no issues playing from your phone or tablet!
