The UK’s Best Online Casinos

With thousands of casinos in existence, it can be difficult separating the wheat from the chaff. But which one is the UK’s Best Online Casino in 2019? All the hugely popular casinos – Mr Green, Vera and JohnVideoslots and Royal Panda to name but a few – have online a large online presence; but does ‘big’ necessarily mean ‘great’? Not always! There are several exceptional casinos that fly under the radar, either because they lack the huge corporate name, or refuse to plough millions into offline advertising.

Here at RightCasino we provide expert UK reviews and are continuously searching for the latest, most reputable casinos for our UK players. The casinos listed below are 100% safe and secure, tested, reviewed and ranked accordingly.

Choosing the best online casino in the UK

Playing at an online casino should be a fun experience. For most players, it’s an enjoyable pastime, and one that’s hopefully rewarded with a touch of good luck. However, not all casinos carry equal standards. One of the first and most important decisions you need to make about gambling online is choosing a casino that’s worthy of your time.

The best casino bonuses & promotions

Every casino tempts beginners in with an enticing welcome bonus. It’s usually in the form of a matched bonus where if you deposit, say, £100, the casino will give you an extra £100 of bonus chips to play with. Of course, you can’t just take this money and say ‘arrivederci’ – you have to wager a certain amount before you can cash in your virtual coins.

Some bonuses and promotions are much better than others, and we scrutinise each and every one, going through the Terms & Conditions in a way that puts Sherlock Holmes to shame. We then report back and tell you just how many magic beans your bonus is likely to get you. Things we look out for include rollover requirements, withdrawal limits, and the time frame available to wager your bonus.

Every member of the RightCasino team is an avid casino player and we aren’t afraid to say that we’ve been around the block more than a few times. So we know what a good casino promotion looks like and we know what kind of ‘bonus’ is not really a bonus at all.

The sad fact is that some casinos don’t mind using vague language, restrictive wagering terms or impossible time limits to squeeze the most out of unsuspecting players. Luckily for our readers, we are always on the lookout for this kind of behaviour and will not feature any casino that does not treat players fairly.

Online casino games

We think that variety is the spice of life when it comes to the best online casinos for UK players. How impressed would you be if you walked into a land-based casino and discovered only a dozen one-armed bandits and a shady-looking dealer offering to play blackjack as long as you used his deck?

A good casino should offer a healthy number of software-based games and live games, though we never forget that it’s about quality over quantity. You will find that rate the different types of casino games as well!

Perhaps the fastest growing category of games is the slot. With humble beginnings, as clunky machines with three reels stashed in the corner of the pub, online slots have become an impressively varied and creative medium. There are slots about pirates, jungles, movies and yes, even fruit slots that harken back to those one-armed bandit days of old.

With so much choice, it can be difficult to find what you want. The casinos feature only host licensed and audited slot games, which have been put through their paces and deemed fully safe and 100% fair and random.

Many players enjoy the live casino experience and indeed, some will play games of that sort to the exclusion of all others. With casino technology improving all the time and your average Joe enjoying internet speeds that were unheard of even just five years ago, live casino is a massive branch of the online gambling industry and is set to keep growing.

Different software providers

Naturally, all these games are created specifically by casino software providers. Some providers – NetEnt, Betsoft, Microgaming and Playtech to name but four – come with superb reputations for creating immersive 3D games. We check to see where casinos source their software to make sure they are legitimate, fair and resilient. We love to see all our favourite games, such as Starburst, Gonzo’s Quest and Jurassic Park. We regularly scrutinise software providers to make sure they honour the published payout percentages of their games.

There’s something comforting in playing a game that has been developed by a studio with years of experience – you know what to expect and it’s usually of a high standard. But we shouldn’t forget the little guys who are just starting out.

Younger, smaller studios are making waves in the online game development sector, bringing fresh ideas to the table and giving players an unparalleled choice of game styles, themes, features and more.

While we’re all for sticking to a reliable brand, we are also endlessly curious and will explore titles by different studios and bring you the latest developments. Studios like Quickspin, Yggdrasil and ELK Studios first appeared on the scene not too long ago and they have already secured their place among the top developers we have today.

Accepted payment options

Of course, you want to get as much cash as you can out of a casino, but you need to get some cash in there in the first place. We review the casino payment options available at each cashier, and again, we think the rule here is ‘the more the merrier’. We like to see credit and debit cards (Visa and MasterCard and more), eWallets (PayPal, Neteller and Skrill) and pre-paid options (Ukash and Paysafecard) covered at the very minimum. We also like to see payment options for worldwide solutions (Sofort Überweisung and Przelewy24 are always good to see) too.

If you do strike lucky, you’ll want to know how willing your potential best online casino is to stump up the cash. What withdrawal options are open to you? Can you have your cash with a snap of your fingers, or do you have to wait 28 days for a personal cheque to pop through your letterbox?

A casino will be awarded the highest cashier rating if it supports manual flushing – the ability to withdraw all funds in one go, no questions asked. Casinos listed on the London Stock Exchange such as 32Red and Ladbrokes support manual flushing.

Casino Platforms

Gambling on the go is soaring in popularity. Top casinos implement a mobile-responsive design, which means that menus remain clear and easy to navigate when shrunk. It’s not just mobile users that casinos should cater for: Mac and Linux players are also on the rise. We provide a frank verdict on the versatility of every casino.

Consult with our list of mobile casinos for 2024, find out in which casinos you can enjoy quality mobile slots and have fun acquiring new gaming experiences at brand new mobile casinos.

The best online casinos around the world

We haven’t forgotten our friends overseas! Although gambling may be regulated differently depending on where you are, all players, no matter their location, want the best experience and the best service for the online casino they choose.

We have looked far and wide for the best Australian online casino no deposit bonus and scoured the web for the best online casinos in Canada. No stone was left unturned for the best online casinos in the USA and we think our hard work will pay off in spades for our readers.

Why choose your best casino here?

When reviewing an online casino we give every criteria a mark out of ten, add it all up and plug it into an algorithm that delivers a final percentage. We scrutinise a casino’s terms and conditions very closely, and test the response times of its customer support. Our top online casinos offer British pounds as a currency option and a wide range of casino games, including blackjack, roulette, slots, mobile casinos and many more!
