666 Casino certainly does pull attention with its name and branding alone. Being an AG Casino, it has to put in effort to look different from its casino peers and siblings. But past the hellfire visuals, things are less rebellious than they seem. As to what exactly is behind the smoke, in this 666 Casino review we will discuss just that.
666 Casino Online started its sinful story in 2018. Behind the red and black visuals with a grinning red mascot that shows up across the site lies Aspire Global, the brand who owns 666 Casino. Those who’ve skimmed through British online casinos definitely heard this name.
While most of the network sites blend games and sports together, this one tries to do its own thing. It’s casino-only, and to compensate for the lack of sports, 666 Casino added even more games to its roster, so both sides equal each other in the end.
The website design has gone through some changes, one wouldn’t guess this is one of Aspire’s casinos at a glance, but traces of their usual layout are still there, we’ve seen most of it before. Sadly, as different as it is, it looks rather dated, even compared to its sister sites.
The devil is in the details though. In early 2025, the Gambling Commission issued a public warning to AG Communications for failing several checks tied to player safety and account monitoring. The fine passed the million-pound mark, and it wasn’t the first time problems had been raised.
An earlier audit in 2022 flagged similar issues, which weren’t fixed when they should have been. After the second fine, they took the necessary action to close the oversights and did keep their UKCG license, we’d still say 666 Casino is trustworthy, you won’t find them on any blacklists.

Company information
There’s no denying that 666 Casino has a strong hook, and the amount of content on offer will appeal to bonus chasers and slot-first players. But besides that, it’s your average AG casino with all the positive and negative traits that come with that.
666 Casino throws its theme right in your face: black, red, and bold graphics built around a cheeky devil mascot and a blazing motto stamped into the logo: Relight your fire. The game icons bring a splash of colour, which works well against the darker layout.
I am not a big fan of the general visual design, it feels very dated and old, and it’d benefit the casino to get a sleeker look. That said, they know how to utilise their space well, and all games are nicely spread out throughout the page
I also didn’t quite like the stylisation. The categories at the top of the page are in a basic font, which makes the interface seem undercooked, and dated.
There’s a FAQ segment under the games that I have conflicting opinions on. On the other hand, it’s nice to have something like this, but the amount of text is just too huge, it takes some time to scroll to the bottom of the page.

The homepage looks clean once the massive welcome banner scrolls out of the way. All main categories are at the top: Slots, Live Casino, Blackjack, Roulette, and Promotions. Above that, there’s a smaller header showing account status, bonuses, balances, and a link to the safer gambling zone. 666 Casino also doesn’t have a Menu option we saw on other casinos from this network which limits the navigation options. As for the footer, it is packed with quick links that are nicely separated into clear columns.
Everything loaded fine most of the time, on some occasions though we did feel a bit of lag when moving between the different sections of the site.
Registration is very fast here, the whole process requires you to fill just two forms. That said, I don’t like that the forms are on a small window with the background of the casino behind it, everything would look much better on a separate page.

666 Casino has apps for both Android and iOS. It’s not every day you see both done well, but here, the mobile version is actually good, both app and the mobile website. The 666 Casino reviews on app stores are decent: the Android version is rated 3.6 while the iOS one stays at 3.0. The main user complaints are not regarding the apps, but about the deposit fees, which we totally get.
The app is easy to find in the Google Play store but you can just use the links in the footer at the 666 Casino site. I was also able to login using my saved info.
The app feels exactly the same as the desktop casino, though not in a bad way, since the general layout is the same, the app is intuitive to use right from the start. I also used the quick access bar quite often, it made moving around so easy. The menu in the top left is just as good to use.
As for the load times, generally, you can switch between pages fast with no lag, but some pages may take a couple of seconds to fully load. As for the game performance, on my machine, it took less than 10 seconds to boot. I didn’t run into any stutter either. The mobile site is pretty much the same as the app, except the loading times are a bit longer.

We walked into 666 Casino expecting a bit more chaos, but we found that the site that plays it surprisingly safe. Behind the fire and brimstone is a fairly standard slot-focused setup. It has over 2,400 games, so we’d say 666 Online Casino suits slot-first players.
The two-deposit welcome deal fits them well, but there are barely any casino deals outside of it, you definitely won’t be getting deals weekly, even with a promo code. Deposits through debit cards + PayPal come with a fee while on the cashout side, you cannot withdraw the whole amount unless it’s a whole number. As good as their game library is, what hurts the positive aspects the most, is the lack of filtering and poor game categorisation. If you’re curious, 666 Casino is worth a spin, just go in with your expectations grounded.
