General Info & Registration

Ready for some devilish casino fun? Then the 666 Casino could be the right gaming hall for it. With Damien the little devil as its host, 666 Casino has been mixing it up in the online gambling industry since 2017 and aims to provide a hellish casino experience. At least, if the makers of the 666 gaming arcade have their way.

In addition to an unusual design and over 666 slot machines and slots from the best software providers, the casino operators are keen to score points with loyal customers with casino bonus promotions and other rewards.

In addition, according to their own statements, security is of high importance. Reason enough for us to subject the gambling house and devil Damien to a close examination. The range of games, the online casino payout ratio, but also the bonus promotions and customer service were important points for our 666 Casino Review, in addition to the security standards and questions about the license.

Game offer

Entering the lobby of the devilish gaming hall reveals the heart of the casino: A colorful assortment of games, ranging from slots to machines to the classics roulette and blackjack. According to its own information, a total of over 666 games are offered.

In order to provide a better overview, the operator has decided on the following division into categories:

  • New – where the very latest games novelties are located.
  • Popular – with the popular slots like Starburst, Jungle Spirit and of course Gonzo’s Quest.
  • Slots – by far the most extensive category with slots like Narcos and Book of the Irish.
  • Jackpots – led by Mega Moolah and Mega Moolah Isis with the progressive prize pools in the millions.
  • Table Games – here you can find the slot versions of Poker, Punto Banco and Baccarat.
  • Blackjack – a selection of the most popular 17 and 4 slot machines.
  • Roulette – with European, French and American versions of the popular casino game.
  • Poker – Wild Poker, Deuces Wild and Jacks Or Better can be found in this category.
    • Fun – with scratch cards and virtual soccer.

The 666 Live Dealer Casino is stocked with games from Evolution Gaming and NetEnt. In addition to Roulette, Blackjack, Baccarat and Poker, Dreamcatcher or Football Studio are also available.

This abundance of different games is possible because the devil among casinos cooperates with a number of the best slot machine manufacturers. Besides NetEnt or Microgaming and the Elk Studio games, you can also find slot rarities from Yoloplay and Sigma Gaming, just to name a few.


666 is, as we all know, the number of the devil and, appropriately enough, it also plays a weighty role in the welcome package: there is up to 666 euros in bonus to be claimed for each of the first three deposits and 66 free spins as an extra. These are the details:

  • 1st deposit – 100% bonus up to 666 euros and 66 bonus spins for Starburst slot;
  • 2nd deposit – 50% bonus up to 666 euro and
  • 3rd deposit – 50% bonus up to 666 euro.

To enjoy these deposit bonuses, you need to deposit at least 20 euros. The bonuses are valid for 30 days, the bonus spins for ten days.

To withdraw the winnings, the bonus conditions stipulate that the deposit amount and the bonus balance must be wagered at least 35 times.

Seriousness & Security

As mentioned at the beginning, the devilish casino is, according to its own statements, concerned with creating a safe and reputable gaming environment. Of course, we wanted to get to the bottom of this as part of our Casino 666 experience and can state pleasant things.

The makers behind the 666 Casino also back up their words with actions and can point to not just one, but three licenses.

The website is operated by White Hat Gaming Limited, which has a license from the Gambling Commission of Great Britain, one from the Swedish gambling authority Spelinspektionen and one from the Malta Gaming Authority. In addition to 666 Casino, White Hat Gaming Ltd. includes around 30 other Internet gaming venues.

The security of the data on the website is ensured by means of TLS v1.2, and the transmission of data is carried out using SSL encryption from RapidSSL. Thus, the casino follows the industry standard and relies on the latest technologies to provide a high standard of data security.

Service & Support

The customer service of 666 Casino can be reached via live chat and email. A hotline was not offered at the time of our online casino test.

The employees are daily, around the clock in use to help with problems and difficulties. This is extremely positive, especially since the help section is very small. Just three questions are answered in the FAQ zone. A bit more could be offered in this area, especially since the competition does not hold back and sometimes offers very extensive help.

Of course, we also took a closer look at the customer service team and can report that the employees were very professional and well-trained.

Deposits & Withdrawals

The range of payment methods is clear and well sorted, although cryptocurrencies such as Bitcoin etc. are not accepted. In detail, the following are available:

  • Visa and Mastercard for credit card payments
  • Paysafecard
  • Skrill
  • Neteller
  • Trustly
  • giropay
  • Instant Bank Transfer
  • Bank Wire
  • Interac Online

For the purposes of anti-money laundering laws, at least when possible, the same method is used for withdrawals as for deposits. In addition, the casino operator reserves the right to request additional documentation for account verification.

For both deposits and withdrawals, a minimum amount of 20 euros applies. A maximum of 5,000 euros in winnings withdrawals can be made per week. Generally, all payments are exempt from fees.

Withdrawal rate

Damien, the devilish host, shows his communicative side when it comes to winning. On the one hand, there is a live ticker in a prominent place on the website with the display of the current winners and on the other hand, details about the RTP of slots and table games can be found under the link Payout Ratios of Games.

The Return To Player (RTP) or the payout ratio is a percentage that indicates how much of the stakes are paid out again to the players in the form of winnings. For example, baccarat pro pays out 98.96%, while some “fun games” such as virtual soccer return 94.4%, and some jackpot games have an RTP of 91%.

Minimum Bet & Limits

Due to the abundance of different slots and machines, it is ensured that there is a game for almost every wallet at 666 Casino.

While slots can often be played with just a few cents per spin, online casino table games can be found with higher limits that can easily go into the four-digit range.

Information on the minimum and maximum stakes can be found directly at the respective game. It is best to start the slot in demo mode and take a look at the rules. This way, it is also possible to play for free without wagering real money. 666 Casino offers this possibility of free testing without registration or account.

Optics & Design

As we all know, there is no accounting for taste and the hell theme may not be everyone’s cup of tea, as well as the black and red color combination that dominates the website. Regardless, it can be said that the site is designed to be user-friendly and should cause few problems even to those with less experience with online casinos.

In the central part you can find the selection of games, help and log in is conveniently located in the top section, where you can also find a link to the promotions page. Everything is where you would usually expect it to be and long searching is not necessary.

Mobile App

The 666 Casino also has a mobile variant, with which the game with the devil Damien can be ventured by means of cell phone, smartphone or tablet. The operator has opted for a web app. Compared to the native apps, this offers the advantage that a download is not necessary, but you can start playing immediately.

All that is required is to enter the URL of the 666 Casino into the browser. The page is automatically adapted to the screen and is compatible with most operating systems.

In addition to the games offered, an account can also be opened or deposits and withdrawals can be made via mobile. In addition, participation in promotions is possible.

Further offers

After the casino start bonus, Devil Damien offers deposit promotions several times a week, with between 10% and 25% of the deposit amount up for grabs as a bonus. At the time of our 666 Casino testing, these were awarded on Mondays, Wednesdays, and just in time for the start of the weekend on Friday.

A minimum deposit amount of 20 euros also applies to these promotions, and the bonus and deposit amount must be wagered 35 times within 30 days.

Although there is a reference to a VIP program, the casino operator does not provide any information about it on the website.

Overall rating

Damien, the little devil, invites you to a hellish gaming pleasure and even after a closer look, you are inclined to follow the invitation. The gaming offer is top, the 666 Euro strong welcome bonus promotions as attractive as well as lucrative and the customer service team is friendly and professional. There are drawbacks – and here we are very picky – with the small FAQ section and the fact that no details about the VIP program are provided. But if you don’t mind that, you can have a thoroughly good time playing with the devil at 666 Casino!
