Say Hello to Our Online Slots Team

Our cherry picked team is made up of online casino experts, who live, breathe, and dream, all things online slots related. As well as playing real money slots games online daily, our team are all devoted casino players. Who hail from the UK and have a vested interest in helping other UK players discover the best online slots sites to gamble at.

Rob Dunstan

Rob started off his online casino career in poker, but after dipping his toe into online slots back in 2012 he was hooked and hasn't looked back since. He's always the first to try out a new slots title and report back on his findings. And having played at hundreds of slots games over the years he's definitely no pushover. Rob doesn't mince his words (or his ratings) when it comes to UK slots casinos.

Sally Myers

Sally used to play at online slots sites purely for the fun of it, but after discovering she had a knack for the game she made her first real money deposit and has been building up her bankroll ever since. She's a particular fan of progressive jackpot slots, even once taking home a slice of the top prize herself. So she's our go to reviewer when a new jackpot slots game hit the marketplace.

Sam Tooley

Sam's an amateur musician and avid movie buff, so when it comes to popular culture slots, he's the man to talk to. When he's not busy tinkering the strings on his guitar Sam can always be found playing slots on any electronic device he can get his hands on, usually the latest smartphone release. This has led to him becoming our mobile slots site guru.

Jake Jackson

Jake used to be a game developer himself so he has a particular interest in the techy aspects of online slots titles. Always putting the graphics and the gaming features under close scrutiny. Nothing gets past his eagle eyes so when it comes to the technical aspects of a slots review Jake is the expert we turn to for the cold hard truth and the techy specs.

What We Do

What We Do

Our mission here at is to help British players enjoy the best online slots experience they possibly can. So we very carefully test out the casinos accepting UK players to see how the player experience pans out. To make sure that all the claims a slots site makes are in fact legit and not designed to dupe unsuspecting real money players.

Only be gaining a first-hand experience of a casino ourselves can we confidentially recommend it to our readers. So, if an online slots casino has received the coveted seal of approval from us, you know it's genuinely a great site to sign-up to.

We rate in a number of different ways - using a strict set of criteria to compare each slots casino side by side. By sticking to the same set of testing criteria, our team can accurately assess which casinos are top dog and which sites need to pull their socks up.

Here's a little taste of what we look for when we're playing at an online slots casino:


Moving your money around online is no laughing matter. Today's top cyber criminals are super savvy when it comes to cracking security measures. So we make sure the slots sites we recommend only use the very best encryption software to protect your sensitive financial data and keep your personal details a closely guarded secret.


Casinos, especially those specialising in slots, love to offer new players a little sweetener for opening up an account and making a first time cash deposit. We carefully test out the bonuses on offer when playing at a new slots site, to make sure the redemption terms are as transparent as the casino makes out.


When we're playing at a UK slots casino we want to make sure any money we deposit is in our account in a flash. We test out the available deposit methods to make sure the processing speeds are as fast as advertised. And to ensure there aren’t any hidden fees or T&C's when it comes to transferring real cash to your online slots account.


Just as quickly as we want our cash to hit our casino accounts, we want to be able to take it back too. Having a speedy withdrawal time ensures you're not waiting weeks to claim your cash back every time you want to withdraw your winnings. Our top slots casinos all offer multiple withdrawal methods and the fastest cashing out speeds.


Nobody likes bad customer service, which is why as part of our reviews process we monitor and test out the customer service of each slots casino we play at. From the responsiveness of the agents, to the times it takes to resolve issues. The most helpful and reactive customer services get a big thumbs up from us.

Behind Our Blacklist

One thing you'll see throughout is our slots blacklist. This is where we effectively name and shame the slots sites that aren't providing a great service or experience to UK online slots players. In short, these particular slots casinos shouldn't be trusted. Some of them may advertise falsely and be caught out for their inaccurate claims. Others are guilty of withholding cash from players, either by prolonging withdrawals or denying payout requests altogether. And others have been rumbled as using rigged games giving players no fair shot at winning back the wagers they're investing.

Whenever you come across a slots casino that's made it into our blacklist you can be sure it's guilty of some form of serious misconduct or bad form. We always encourage our readers to only play at real money slots sites we recommend and avoid the ones included in our blacklist at all costs.

Why Finding a Top Slots Site Matters

You might think all slots sites are created equal, but take it from us, they most definitely aren't. The breadth of different online casinos offering slots titles online varies dramatically. Not just in the selection of games on offer but in terms of other important player benefits, such as response times, bonuses, and real money rewards.

That's why it's so important to find the right slots casino for you. Because if you're going to be investing your time, not to mention your hard earned British pounds, you want to ensure you've made the right decision.

Mobile v Desktop Casinos

Mobile v Desktop Casinos

The first thing to consider when deciding on a slots casino to open an account at in 2024 is how you intend to access the casino. By which we mean, what device, or devices, are you likely to be using when you play slots. If you're someone who spends a lot of time away from home, and tends to access online casinos on the move. Then choosing a slots site that is optimised for mobile gameplay should be a top priority for you.

The best mobile slots casinos offer a full range of games on a wide array of smartphone and tablet devices. With apps and interfaces that have been specifically optimised to ensure the smoothest experience on your device. For example, it's no good trying to access an online casino on your smart watch that hasn't been developed for the smart watch platform. Casinos built for this particular mobile device need to dial back on the graphics to work around the small screen display size.

So carefully consider the ways you'll want to access your chosen slots casino to make sure the site offers a mobile platform that works for your device.

Funding Your Account

If you have a preferred way of moving cash around online, or you're limited in terms of the deposit methods available to you, check to ensure the slots casino you've set your sights on is equipped to accept your deposit method as payment.

The top slots casinos all offer multiple ways to transfer cash to your casino account. But not all banking methods are instant, and some may incur fees too. So it's important to establish how you will top up your slots account before you sign-up to a casino. While registering for a new account doesn't take long, it can be frustrating going through the motions only to discover your deposit method isn't accepted as currency.

It's also worth pointing out that the majority of casinos will require you to use the same banking method to make withdrawals as well as deposits. Something to bear in mind when electing a deposit method to pay with. As some e-wallets for example, charge handling fees for accepting cash on your behalf, even if they don't charge you for making a payment.

Legit & Licenced Casinos

Even in 2024 you don't have to be an established organisation to set-up a casino online. Any Bob, Dick, or Harry who fancies themselves as a casino operator can open up an online real money gaming site. Even if they don't have the first clue about what they're doing.

That's why it's so important to check the credentials of the slots site you're signing up with to make sure it has the necessary certifications to prove its validity. Only genuine casinos will be licenced and endorsed by recognised gambling associations in the UK, so you can tell right away if a site is a rogue operation if it's missing these crucial accreditations. If a slots casino can't prove authenticity, our advice would be to just walk away.

As our reviews process has proven, the UK online gambling landscape is bursting with great legit slots sites, so don't chance your luck at a site you suspect is rogue. Trust our expert's recommendations, and enjoy the great rewards, bonuses, and real money slots action.
