About 666 Casino

666 Casino was established in 2018 and since then has made a rather hellish name for itself – and we don’t mean that in a bad way! The website itself is black, highlighted by some flames, all designed to put you in mind of the Devil himself. Despite this design, the way it works couldn’t be better. The casino offers a huge range of games and excellent bonuses, all of which is covered in layers of security so that those demons out there won’t be getting their hands on your private data anytime soon!

666 Casino License and Security

The demons running 666 Casino have done their job well; the casino is licensed by both the Malta Gaming Authority and the UK Gambling Commission. Both of these jurisdictions boast some serious top-level rules and regulations, which help to protect players and which casinos must abide by if they wish to continue operating under their licenses. The casino also has SSL encryption protocols in place to ensure that player data doesn’t fall into the wrong corrupt hands, allowing players to deposit money with ease.

666 Casino Bonus

As with any online casino, the way to bring in new players is through a series of bonuses and promotions. 666 Casino does a devilishly good job in this area by offering players not only welcome bonuses but a series of promotions that are on-going, provided you stick around at the casino. And why would you not? These bonuses can help to kick start your online gaming and take it to a whole new level, without you having to put too much money down yourself.

666 Casino Welcome Bonus

The big bonus here is the welcome bonus. This continues the 666 themes by offering players as much as £666 in welcome cash across the first three deposits. There are also 66 free spins to be grabbed when you make use of this bonus. The first deposit offers up a 100% match deposit whilst the second and third deposits only match at 50%. However, you do have the chance to reap as much as £2000 in extra cash if you deposit the maximum each time.

Regular Tournaments and Bonus Promotions

There are a large number of bonus options available and these change depending on the weekday. There’s a Manic Monday bonus that manages to make Monday’s somewhat less hellish than usual by giving a 10% match bonus on every £50 deposited. Wednesday offers a 25% match bonus, again up to £50 with an extra £5 for each additional £20 deposited. Finally, the weekend sees another 25% match deposit come your way giving you that little bit extra to get playing with while you relax.

666 Casino Loyalty Programme

What’s even better, the bonuses don’t stop here. There’s a loyalty points programme in place too. The moment you sign up and make a deposit, you’re rewarded with 500 loyalty points. Every time you make a wager on a game, you’ll get extra points. However, table games only award 0.25 points for every £10 wagered whilst the slots or scratchcard games offer up 2 points per £10. Reaching 10,000 points will see you get £5 in bonus money to play with on the site.

666 Casino Games

There are a large, and growing, number of casino games on this site. The majority of these are slot games, though, and the variety is enormous. These are set out in a convenient grid format alongside some simple filters so you can find exactly what you’re looking for. There’s a whole range of themes, types and in-game bonus features available, not to mention a rather decent set of progressive jackpot games to choose from as well. All in all, they’ve done rather well here in providing a good set of options.

There are also a large number of different virtual table games to choose from. There are over 20 different blackjack versions just for starters. The collection also includes a number of roulette options as well as baccarat, Oasis Poker, Caribbean Stud and Casino Hold’em. Players who enjoy video poker will also find that the devil has ensured they will be satisfied too as there are over 10 different options to choose between. The collection is constantly growing too, so it’s worth checking in now and then.

666 Casino Live casino

666 Casino’s live dealer game section leaves absolutely nothing to be desired. Thanks to the pairing of NetEnt and Evolution Gaming, the live games have covered a very comprehensive selection. Do you want standard table games? You’ve got them. Something more unusual? You’ve got game shows in the form of Dream Catcher and Deal or No Deal and even a Live Football studio to keep you updated on sports as you play. Better still, there are even some helpful gaming strategies provided by the casino too!

666 Mobile Casino

Whilst there isn’t an actual app dedicated to 666 Casino, there is a mobile optimised site. In this day and age, this is possibly even more important than an app as it saves on having to make any downloads. Instead, you can simply load up the casino site in your mobile browser, and you’ll be treated to the same setup, games and features as the desktop site. Available for iOS and Android devices, you’ll find yourself able to seamlessly jump between the two platforms so you can play whenever and wherever you are.

666 Casino Payment Methods

The devil has made sure that you’ll succumb to temptation by offering a complete range of payment methods for both withdrawals and deposits. Deposits appear lighting fast in your account so that you can get playing as soon as you can! Withdrawals do take slightly longer as the casino does have to go through a short processing time before the money can be released to you. As a general rule, it’s the eWallets that are fastest, usually about 2 working days, if you’re eager to get your hands on your winnings!

666 Casino Customer Service

Great customer service is a must when everything is online. Players at 666 Casino are treated to fast and helpful service via the live chat function. This is operational 24/7 so no matter when an issue strikes; someone is ready to help. You can also contact them via an email, but this does take a little longer. There’s a very short, not entirely great, FAQ section, so it’s worth making contact with a staff member if there are any issues – they’ll sort it out much faster.


Despite its demonic presence, 666 Casino offers a rather angelic and easy-to-use interface. The game selection is excellent, the bonuses large and the security and customer service is easily on par with sites that have been around a lot longer. Maybe it’s true that the devil is in the detail, but these details are really in the player’s favour, so we suggest putting any superstition aside and trying out this unusual, yet potentially lucrative, gaming site. Maybe 666 will be your lucky number!
