Top 20 Online Casinos UK – A Definitive UK Casinos List
The Professor has never seen iGaming as busy, and this has compelled him to create his very own top 20 online casinos UK list. New platforms are popping up left, right and centre – with many being certified UK online casinos thanks to their acquisition of a Gambling Commission license. But with so many options, how do British players distinguish top casinos in the UK from the fakers?
As the Professor can’t create a unique article for everyone, it’s impossible for him to pluck out just one casino and call it the “best”. Instead, he’d like to run you through his top 20 online casinos UK – in no specific order – and briefly explain why each one made the cut.
Are you sitting comfortably?
Dunder
No Deposit Bonus
20 Bonus SpinsFirst Deposit Bonus
100% up to £100 OR 200% up to €50One of the most stripped back, classic casino sites around, Dunder has been live since 2016. Yet, that stat seems incredible considering the popularity they’ve built up in such a short space of time! A true gift for the gamers amongst us.
Why Dunder? The SMS, two-factor security feature. It’s a staple in other areas of the internet, but not everpresent in iGaming – even for most top 20 online casinos UK!
Casumo
No Deposit Bonus
30 Free Spins (No Wagering - UK!)First Deposit Bonus
100% up to € / £300Play now18+. New UK customers only. 100% deposit bonus up to £300. Opt-in required.

The birth of the so-called adventure casino happened in 2012 with the launch of Casumo. This completely new experience revolutionised iGaming, with several mimicks and clones trying to replicate success. Casumo have since racked up multiple awards for their efforts (Casumo Wikipedia – Awards).
Why Casumo? There’s no substitute for the real thing, so Casumo sailed into the Professor’s top 20 online casinos UK list.
Rizk
No Deposit Bonus
1 x Wheel of Rizk - Win Spins or Cash!First Deposit Bonus
100% up to £100 + 50 FSThe superhero of UK casino sites is Captain Rizk, with this protagonist on a mission to offer players “no bullshit” rewards. Rizk have had famous faces promote this message down the years, but it’s really because of their website for both mobile and desktop that – to borrow a famous Apple link – just works.
Why Rizk? The Wheel of Rizk! Give it a spin to get a casino bonus with no wagering every time!
Mr Green
No Deposit Bonus
EXCL: 40 Bonus SpinsFirst Deposit Bonus
100% up to £/€100 + 100 FSPlay nowNew players only. 18+ www.begambleaware.org. 35x wagering applies to Bonus Cash and Spins.

If Captain Rizk is the superhero, Mr Green is the most stylish. This slick operator makes this top UK casinos list with ease, and he also happens to have forged a strong bond with the Professor too! Check out our exclusive casino bonus from Mr Green for something a little different.
Why Mr Green? They know how to look after players – see their Promotions page, slot tournaments and Green VIP club for more.
Videoslots
While not exclusive to us, Videoslots have a funky welcome bonus that’s sure to catch the eye. It includes wager-free spins, up to £200 as a bonus, plus £10 extra cash thrown in. Maybe you can use some of this to take part in a Battle of Slots – which is Videoslots’ poker-style competitions, in case you were wondering.
Why Videoslots? The sheer number of slots and games at this top 20 online casino UK is ridiculous – 3,000+ and counting!
LeoVegas

If Casumo pioneered the adventure theme, LeoVegas proclaims to be the “King of Mobile Casino” – and who can really argue with that!? They undoubtedly played a huge part in driving iGaming to smartphones/tablets, Android/iPhones – so they’re another easy addition to the top 20 online casinos UK.
Why LeoVegas? Use previous eBay activity to your advantage by depositing via PayPal at LeoVegas.
LV BET
Similarly to the gentleman, the Professor has also pulled some strings with LV BET – this time to bring you exclusive free spins no deposit! Once you’re done with that, up to £1,000 and 1,000 LV Spins could be yours over the course of four deposits, but that’s not all LV BET have on the menu.

Royal Panda

Highroller
