Top 20 Online Casinos UK – View 20 best online casinos

New platforms with a UK Gambling Commission license are popping up all over. But with so many options, how do British players distinguish top online casinos in UK from the average?

This compelled us to select our top 20 online casinos UK for Casino Professor. All our chosen sites have the basics in place – plenty of games from good providers, strong security, support for desktop and mobile devices etc – but the very best sites offer more than just that.

Therefore, we’ve carefully picked out each site for a reason – and we explain exactly why we think they are one of the top 20 UK casinos currently. Are you sitting comfortably?

1. Rizk Casino

The superhero of UK casino sites is Captain Rizk, with this protagonist on a mission to offer players “no bullshit” rewards (e.g, they are our best £20 free no deposit casino!). 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.
