The internet is home to thousands of betting- and online casino sites. International gambling companies often have the full package to offer their customers: betting, casino, live casino, scratchers, online poker and bingo. Some companies are focused only on one or a few of these.

On this page you can find all the online gambling companies we’ve tested and found safe and secure to be recommended for UK players. Note that UK players don’t have any restrictions on betting and playing on the international sites we’ve listed. You can try out new sites and companies without having to worry while enjoying their bonuses and campaigns. This list contains only reliable companies.


Then you’ve come to the right place. All members of our reward-winning team of writers specialize in online casinos and games, while their passion for the business is unrivalled! Our online casino comparison system means that you can join the wonderful world of online casinos without any risk of falling for a hoax.

The list contains only sites that we’ve thoroughly tested and that meet our high standards of quality. All reviews have been conducted based on actual experiences of the site by a person with a lot of experience in the industry.


Casino rankings and their star ratings are based purely on our experiences and opinions of the site. We never give out good rankings or a lot of stars to gain financial profit from ad revenue etc. At TurtleBet, we prioritize our readers. Our goal is to provide online casino players with material that is genuinely helpful.


We have good news for players worried about the legal issues about gambling at international online casinos. All of the sites on our list are licensed by the United Kingdom Gambling Commission, which not only means that playing on them is completely legal, but also that all winnings from the sites are completely tax-free! 

All sites also have fast and reliable customer service in English, while they also offer multiple money transferring options for UK based players.
