666 Casino Review

Last update: 14th January 2026

4.6/5

666 Casino was previously on the White Hat platform but moved to Aspire in December 2022. It’s well worth a visit even if it’s just to see the theming!

About 666 Casino

666 Casino originally opened in 2017 as a White Hat Gaming casino but moved to the Aspire Global platform in 2022. Since it had already been a fairly successful site under its original management, it’s nice to see that much about the site’s design and operation has been preserved.

The theme is so out-there, it’s actually somewhat refreshing. At a time when more online casinos seem to be leaning more into minimalism, the kooky theme of 666 Casino really stands out.

666 is of course the number of the beast and 666 Casino is fronted by the Devil.  Except he’s not at all scary, but funny in a uniquely British way – in fact he has to be seen to be believed! There are some nice little touches like menu icons depicting a pitchfork, pentagram and a hand doing the devil horns and, while the theming doesn’t quite permeate the promotions, it’s still fun to just experience something so unique in what’s becoming such a saturated market.

Slot Games At 666 Casino

The section that stands out most at 666 Casino is the slots lobby, where over 1,500 slots can be found from more than 30 studios. It’s a nice mix of both larger-scale game studios like Net Ent and Games Global and smaller, independent providers like Hacksaw. This means that there’s lots to explore, so you can try out more unusual, niche titles like Twisted Lab Rotogrid, where the actual set of reels rotates throughout the game, along with more classic games like Book of Dead.

You can also try out Slingo – a combination of slots and bingo. There are a few dozen variants on the site, including Slingo Starburst and Slingo Tetris.

Once you’ve clicked on Slots, the handy sections disappear and are just replaced by a bunch of game thumbnails in what seems to be a random order. So unless you know exactly which slot you want to play or which studio you want to filter them by, this area can be a little bit difficult to navigate.

For those of you who want to browse around and check out the newest games or the casino’s top picks, it’s best to look through the main Games page. While it’s not designed to cater specifically to slots players, the site still provides some useful recommendations on what to play next.

Speaking of browsing, it’s a lot of clicking and loading. Basically – you have to click on a game, wait for it to load and take a look at the paytable to know what it’s all about. There isn’t really any information on each game directly in the lobby. So, 666 seems to be geared more towards players who are already familiar with the slots available on the site; it’s not exactly the fount of all slots knowledge.

It would also be quite useful if there were some way to save the games that you play often – even a Recently Played section would help, rather than having to search for your favourite games again every time you log in.

While the layout of the site leaves something to be desired, the actual maintenance is great. New games are added to 666 Casino almost every day. There’s always something new to try, and you can tell that the team at 666 are keen to keep players interested by bringing them fresh experiences.

Other Games at 666 Casino

Aside from slots, you’ll find a few table games and live casino games. There are well over 100 games in the live casino section, all powered by Evolution Gaming. Classics like Roulette and Blackjack can be found here, as well as funkier titles like Dream Catcher and Crazy Time.

In terms of RNG table games, there are a few spattered here and there amongst the live casino games.

Other Things To Consider

We mentioned earlier that 666 falls under the umbrella of Aspire Global which is quite a large group with lots of sister casinos. Normally, in these situations, each site is a reskin of a reskin of a reskin, but that’s not the case here. 666 is actually quite unique to the other sites in the group – not just in looks but in terms of game selection and promotions.

In the Promotions area, the welcome offer gets you off to a good start and there are plenty of other bonuses that follow. Leaderboard tournaments and daily free spins (when you wager £100 or more) are regularly available, and there are a few in-game promotions available thrown into the mix as well, like Pragmatic Play’s Drops and Wins.

666 Casino doesn’t have a loyalty program or VIP program – not for UK players, at any rate.

Final Thoughts

666 Casino has a quirky charm that’s eye-catching, to say the least. What makes it stand out isn’t just the branding, but also the commitment to keeping the experience fresh, with new games popping up all the time. The site may lack a loyalty program or VIP perks, but it seems like the owners recognise 666 Casino’s players are more interested in the fun of the gameplay rather than climbing the ranks.

So, if you’re looking for a casino that breaks from the usual mould and offers a unique atmosphere with plenty of options to explore, 666 Casino could be worth a visit. It’s a fun place for players who like that little bit of mischief.
