Safety and security for UK players is one of our primary concerns when we assembled this 666 Casino review.  

You’ll be glad to hear that the operator holds a United Kingdom Gambling Commission (UKGC) license, meaning UK players are protected.  

Why does this matter? First, UKGC guarantees the fairness of games, and that all numbers generated are completely random. Second, finances must be held in a separate account to 666 Casinos, therefore when you win, you can withdraw right away.  

If you ever have any problems with being paid out, you can submit a request to UKGC, which gives you peace of mind when you play games at 666 Casino.

Currently, there is no 666 Casino app to speak of, either for Android or iOS. However, if you wish to play on your smartphone then no problem.

Just open up your preferred browser e.g. Safari or Chrome, search 666 Casino and login into your account. The site is responsive to any screen size, and the even better news is that all the games available on a computer can be played on a smartphone too.

We tested the platform for the quality of customer support while we assembled this 666 Casino review.  

On the whole, 666 Casino does a good job, but improvements could be made. First, to access the live chat you must be registered, which can be irritating if you want to ask questions before signing up.

No email, but a contact form

While we made this 666 Casino review, the aspect that impressed us the most was the amount of games available to play.  

With 1500+ titles, from the latest online slots to live dealer games such as online roulette and blackjack, 666 Casino goes above and beyond.  

One area that could be improved is customer support. We would like to see a 24/7 live chat open to everyone rather than just registered players.  

Yet, the banking options are way above average for the industry, with 10+ options to choose from.  

There are no concerns about safety either, as the website is properly licensed by the UKGC. Moreover, it uses state of the art SSL technology to keep your financial and personal data safe.
