How do we Review the New Online Slot Sites?


With the market so popular and busy seeing new slot sites launching in what seems like every day, players can find themselves potentially signed up with an unreliable or unsafe new slot site. Fortunately, our team of slot experts at Gambling.com has put together a list of reliable and safe slot sites that launched this year, with most having launched in the last few weeks or months, so players have plenty of choice without incurring risk.

When writing our review on every new slot site in the UK, we carefully check that it is licensed by the UKGC, as well as its overall reputation and trustworthiness amongst players. Therefore when it comes to finding the safe slot casinos, we do all the investigative work for you and only feature and recommend on our site the new online slot sites that are 100% legal, safe and reliable. Sticking to new slot sites we've reviewed and confirmed the validity of will ensure players are never spinning with a new site that's unregulated, unsafe or unreliable.

Along with our expert list of the best online casinos, this guide will help players understand where it is best to find the newest slot casinos, choose which site to pick when presented with a bunch of different quality sites, and even help players gain a grasp on why slot sites have become so popular.

There are many new UK slot sites to choose from but we have done the hard work for you and put together a list of the best quality, most reliable and safe slot sites that launched in the past few weeks and months. We've gone deep and reviewed the sites against a list of standard industry benchmarks - only the best and most reliable make our list, and of course the ones that provide the best terms of bonuses, customer loyalty, service, game selection, payment methods and overall experience. So now that you know about how much work we've put into bringing you the best options amongst new 2020 slots sites, let's look at which ones might be best for you and why.

Why Choose New UK Slots Sites?

As the UK online casino market that is one of the most established in the world, a new slots site must be innovative and bring something different, exciting and new if it wants to break into the marketplace and make an impact with players. For this reason, nearly all the new slot sites in 2020 bring something new to the party and beyond proving a totally new and exciting user experience, new slot sites in the UK simply try harder! This shows in generous bonuses, loyalty programs, customer support and more.

Here are a few reasons you should choose new online slots sites:

Discover the Latest Online Slots

New online casinos that feature the latest slots launch in the UK all the time. It's a very wide market for any new player that is looking to experience casual casino fun are drawn to the thousands of colourful and exciting new online slots. In addition, veteran casino players that have traditionally been playing casino table games are increasingly attracted to new slot games because of the innovative features, multiple paylines, high payouts and more ways to win.

Some players who sign up to an online casino for the first time can be confused by the massive variety that includes hundreds, and even thousands of different slots offered on a single site. Finding the newest slot sites isn't always the easiest task since search engines don't always have the newest sites indexed yet and the exposure to these new slots sites may be limited. Marketing is expensive and word to mouth can sometimes be slow, so many new UK slots sites struggle to get their games in front of the public.

And that's exactly where we come in! Our experienced casino experts who thoroughly review each new slots-based casino site listed in this guide not only ensure that they are all fully regulated, safe and secure. But they also scour each site and check if it features the latest games and most popular software providers. And of course, one of the most important items on our checklist is the generous welcome bonus new slot sites usually provide.

New Slot Sites Bonuses in the UK


With new online slots sites launching in the UK every month, innovation and quality are becoming the standard. So one more way new slot sites in 2020 use to differentiate themselves is by the bonuses, promotions and rewards they offer players. Starting with the welcome offers that are given to new players, brand new slot sites usually offer:

Besides enticing new players, new online slot sites understand that their livelihood also depends on their ability to retain players and keep them coming back. Therefore they also offer attractive promotions and loyalty programs to returning players. Here are a few ways new online slot sites in the UK reward the loyalty of their returning players:

Beyond the large sums of money that are offered through bonuses, promotions and rewards, it is also a great way to try new slot games and enjoy a well-rounded, fresh slot experience. Make sure you read our reviews which always cover in detail promotions and reward programs for each new slot site.

New Slot Sites with a Free Sign up Bonus

Who doesn't love to get something for free? As that of course includes seasoned slot players like you, many new slot sites offer a free sign up bonus as a way to entice new players and let them try a casino without any risk. Simply register and either enter a bonus code or in some cases the casino will automatically credit bonus money or bonus spins to your account balance. Make sure you register through our site, as many of the free sign up bonuses we feature are available exclusively to Gambling.com users.

Many players highly appreciate new slot sites that offer a free sign up bonus as it shows generosity and commitment to customer service. It is still important to note that winnings are subject to the casino's wagering requirements (the number of times you will have to play through the bonus before it can be redeemed into cash and become eligible for withdrawal). So always check our reviews for wagering requirements as well as the casino's bonus Terms & Conditions.

New Mobile Slot Sites in the UK

Many online slots players in the UK enjoy spinning the reels on their mobile devices. In fact, mobile slots are so popular that any new online casino will see more players clearly preferring mobile slots to desktop ones. For this reason, most of the new mobile slot sites were built with the mobile-first approach in mind, offering a smooth and elegant mobile experience at every level.

Mobile slot players in the UK can enjoy a great mobile client for instant access to new mobile slots through any device browser. Numerous new slot sites in 2020 took their mobile slots experience even further by offering slots apps that can be download and installed on iOS and Android mobile devices.

Brand New Slot Sites Payout Rates

The payout rate of a slot machine is defined as the percentage an online slot will pay back to players in winnings over time. This payout is also known as RTP (Return to Player) percentage, whereas slot machines at land-based casinos have an average RTP of 75%, online slots boast a much higher average of around 95%. This is why many slot developers and slot sites proudly advertise game RTP as a positive selling point.

Furthermore, new slot sites in 2020 advertise the average RTP percentage across all their slot portfolio in addition to advertising individual game RTPs. We encourage this transparency and will always display RTP information on our reviews whenever it is available. This will enable you to make the most informative comparison between slot sites and individual slot games.

New Slot Site Game Developers


Online slot players like to play on a variety of the best slots brought by the top-ranking software developers in the world. Therefore new slot sites compete for players by constantly looking to add to their site new games from existing slot developers, as well as establish relationships with innovative, new game providers. Some of the most prominent game developers that power new slot sites in the UK are long-standing providers that have been dedicated almost exclusively to online games such as:

Other popular game suppliers have started in brick-and-mortar casinos and then moved on to provide their beloved land-based slots to online players. These include:

There are also many specialised game studios like iSoftBet, Lighting Box Games, Thunderkick and SkyWind that although releasing fewer slots every month, still have a big following because of their unique game design, themes and features. If you are interested in new, unique and innovative games aside from the popular classic titles, it's always best to look into new online slots sites because in many cases they are more open to bringing on board smaller game studios. So make sure you check our reviews of the best new online slot sites in 2020 to always stay informed about what's new!
