666 Casino Review

If we went back a bit more than a couple of decades, a name like 666 Casino would have all sorts of bad connotations. Now it’s just something of a popular reference, and certainly an interesting theme and concept for the casino. Let’s be clear though, this is all tongue-in-cheek and just something to chuckle at as you spin away at the slots. The hellish theme doesn’t translate into a hellish experience, on the contrary, this casino site has plenty to offer for all sorts of players.

666 casino is partly operated under White Hat Gaming Limited, who is a white label provider. There are dozens of other casinos under their wing, and quite a few of these come with similar characteristics. Plenty of banking options, superb licenses and a list of game providers that takes time to read through. These things apply to 666 online casino site too, but that doesn’t mean it’s a simple template casino. Let’s take a look at what truly makes this casino what it is.

The 666 casino holds a good reputation and has done so since being established in 2017. The same applies to the sister sites in the same network. Even when combing the internet for serious complaints we couldn’t really find anything else, except some momentary lapses in account management, which were usually quickly resolved.

This casino site is heavily invested in what we consider the essence of casino gaming, that is slots, table games and classic casino titles like video poker. You won’t find anything else, whether that is live casino, sports betting or bingo and poker products.

Though usable on all devices, the 666 casino site sometimes comes with an abundance of text that is not quite fitting for smaller screens. On the other hand, the games and other activities don’t really suffer from this issue.

666 Casino Bonuses

Bonus offers at 666 casino follow a rather familiar setup. Welcome packages, weekly bonuses, monthly bonuses and loyalty points. Bonus cash and free spins are a staple diet at the site, though you shouldn’t expect much in the way of free no deposit bonuses. You might also run into cashback offers. Besides bonuses that come in packages, you can also expect to get offers directly to your email.

Wagering requirements are usually set at 35x, whereas the minimum deposit is €20 or equivalent for pretty much all the offers at 666 casino. We didn’t spot any predatory terms or win limits, but did notice that some of the promotions are specific to certain countries. This is due to the license rules.

Do notice that the casino does sometimes cap the wins from free spins, but only if you do not use them immediately after you make your deposit. Be sure to always play your free spins first at casino 666!

Regulars are taken care of at 666 online casino. You always have the chance of climbing the ladder at the VIP club, though you first need to deposit quite a bit to get an invitation to join. Another option is going for the loyalty points, which you earn automatically as you play at the site. It’s quite a standard setup, which means that as soon as you have enough loyalty points you can exchange them for bonus money, which then requires the normal wagering before being turned into cold hard cash.


Though rich in bonus offers, the matter is a bit different when it comes to promotions. That is, we couldn’t really find much that would be a special promotion as opposed to just being a regular bonus offer. No slot tournaments here, which is pretty much in line with the rest of the online casinos that belong to the same network of online casino sites.

You could count the occasional free no deposit bonuses as promotions, as they are handed out from time to time at 666. Terms and conditions for these are so and so, as the wins are often limited to certain maximum amounts. On the other hand, being completely free, that is not really a negative mark in our reviews. All in all, we’d welcome tournaments, developer promotions and other such forms of bonuses in addition to the ones that are already present.

666 Casino Games

The list of developers is quite impressive, and keeps on growing and changing. You can find dozens of big providers, complemented by dozens of boutique publishers. This creates a massive and varied selection of online slots to browse, try out and bet on. If you are into spinning slots, you won’t run out of spins and slots to enjoy at 666 casino.

Rather surprisingly, the 666 casino does not offer a live casino. There is a wide variety of table games available to make up for this. In such numbers in fact, that the roulette, blackjack and other table games have their own categories to make selecting your favourite that much easier.

The games are divided into easy and neat categories, easily accessible from any part of the website. Just enter the casino lobby of 666, select your favourite type of games and you’re ready to spin as many excellent slots as you could ever want.

Available games

Slots and software

The number of software developers at 666 online casino is enough to overcrowd even the pits of hell. The hundreds, if not thousands, of slot titles, are offered by a group of big and small gaming companies alike. All in all, you can find everything from 1×2 Gaming to Yoloplay.

Besides the categories, which already narrow down the collection of games to more manageable numbers, you can also order the games by filters such as popular or new. The search function helps you find the titles that you want. If you are a fan of a particular gaming studio you can also use the filter to just show slots and other games from that provider.

You can find jackpot games, as well as Megaways games, at 666 online casino. For some reason, these games don’t have a section of their own, despite the considerable popularity that jackpots enjoy amongst players of all kinds.

Two sections that are a bit out of the ordinary is video poker and aptly named “fun”. The latter offers scratch cards, experimental games and other curiosities. The poker section offers video poker titles, though not in considerable numbers. Still, if you are after jacks or better, or other similar titles they should be easy to find.

We’ve read some reports about long loading times when playing with mobile devices, but we suspect these are simple internet issues. As long as your favourite device is armed with a strong internet connection and a modern web browser you can easily enjoy the games that 666 casino offers.

Deposit and withdrawals

666 online casino offers all the usual payment methods, plus some that are specific to certain market areas. From credit and debit cards to e-wallets, online banks and prepaid cards, pretty much every method of transferring money is available.

Though, do note that cryptocurrencies are not supported as of yet. Furthermore, some deposit and withdrawal methods come with special rules, such as not being available for bonuses. But then this is the case with most online casinos.

The minimum deposit at 666 online casino is €10 or equivalent, though bonus offers require double that. Maximum deposit depends on the deposit method you are using, and these are best checked at the deposit page via your account at 666 online casino.

Deposits and withdrawals are not subject to any fees from the casino itself. However, this doesn’t mean that they come completely free, for example, if your bank charges fees for making transfers the players still need to pay those.

The minimum withdrawal for any single transaction is €20 or equivalent. The maximum withdrawal is €5,000 per week, though this can be considerably higher for VIP players.

Once a withdrawal is requested the payment remains pending for one to two days. After it is processed it should hit the player account within the normal timeframe, which is instant for E-wallets, and from one to five days to credit cards and the like.

Verification documents are usually requested as soon as you make a withdrawal, which is in line with the many licenses that this casino site holds.

Security and Licensing

This casino site holds the same license as many other White Hat Gaming sites. That is, the British and Maltese licenses. These are two of the strongest gambling jurisdictions there are, which is quite enough to vouch for security and safety at 666 online casino. This is further reinforced with 3rd party mediation tools, which means that if a player has a complaint about 666 casino, they can certainly make their voice heard.

From the technical perspective, you can expect a protected connection (SSL obviously), as well as certificates for all the servers, random number generators and the like. This is further enhanced, once again, by the licenses that force additional bells and whistles to make sure that your personal information and your funds are always safe at 666 online casino.
