Community & Customer Service

Unlike many other comparable sites, 666Casino UK has a distinctive personality, and features a lively hellish theme (although this is all done in fun and is not meant to be taken too seriously!).


  • Facebook
  • Twitter

Although there is a clear theme to this site, with the absurd devil character appearing on most pages, the focus here is essentially on the games rather than a playing community. There is a Twitter account (@666_casino) and a Facebook page (@666Casino), but these have not been active for some time and so are not an effective method of communication.

Customer Service

  • Email
  • FAQs

You can contact the customer support team via email at [email protected], with the customer services team available to answer your inquiries between 8 am-midnight (CET). There are also several FAQ pages that contain useful information that can answer the most common questions.

666 Casino on Mobile

The 666 Casino mobile site has a stark, contemporary design, but this works extremely well, particularly on the smaller screens of phones where it produces a very clear and easy-to-use UI. You get quick and easy access to all games and menus from the home screen, and the range of games here is comparable to that at the desktop site, with video and progressive jackpot slots, table games and live dealer games.

There is no 666 Casino app to download and install, as all games are browser-based. What this means for you is that you can play on any device, including Apple iPhone and iPad, Android smartphones and tablets, or any portable device with a browser and internet connectivity.

Our Take on 666 Casino

The range of 666 Casino mobile slots is excellent, and the site is well designed with a UI that makes it easy to navigate on the smaller screens of phones and tablets. The search function is very useful and enables you to search the 1000+ games by theme and studio, as well as by category of game, e.g., jackpot, Megaways, Drops & Win etc.

All of the slots are designed to be played directly in the browser of your device, so there is no 666Casino app to download and install. You can also make deposits and withdrawals and contact customer support easily in the 666 mobile casino.

Should I Play at 666 Casino?

If you like a casino with a bright and colourful design, and which has a huge range of games but is still easy to navigate and use, then it’s going to be worth your while to check out 666Casino UK. The range of 1000+ game covers all playing tastes, and the large selection of Megaways slots and Drops & Win slots gives the site extra appeal. The exceptional number of live dealer games is another standout feature, so you get an all-round gaming experience (although some players will probably miss some of the big money progressive jackpot slots).

The 666 mobile casino also provides an excellent playing experience, with the high-quality games responsive to any size of screen.

Worst pay rate ever. I played over 1000 spins on £1 on legacy of the dead slot with no bonus! I have played around 30 different sites and almost every game and never in 5 years have experienced this. Total rubbish.
