Top 20 Online Casinos UK - View best online casinos UK

With the online casino world busier than ever before, we’ve made it easier for Brits to get a taste of the action with our very own top 20 online casinos UK. Open up the following selection of our 20 best online casinos to see who we’ve chosen.

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?

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!).
