666 Casino Bonuses and Promotions

One thing we’re sure you’re all eager to find out is what the 666 Casino bonuses and promotions are like. Well, while the welcome bonus is certainly worth claiming, there isn’t much in the way of ongoing promotions for existing players. 

Let’s start with the positives - the welcome package is available to every new player at 666 Casino and offers players a £66 casino bonus, plus 66 free spins on the popular Big Bass Bonanza slot. To claim the full bonus, make two qualifying deposits of £20 or more; you’ll receive the matched deposit bonus on your first deposit and your 66 free spins on your second deposit. 

On the other hand, the 666Casino promotions are basically non-existent! The only other offer our experts could find on the promotions page was for Drops & Wins slots. To be fair to 666 Casino, they’re offering £2 million in prizes every month, which is nothing to sneeze at, but we’d like to see a bit more variety in the promotions they offer.  

➸ Loyalty Programs 

666Casino currently does not offer any form of loyalty program to its customers. However, we’d recommend regularly checking the Promotions tab to ensure you’re getting the best offers available on the site. 

➸ Tips & Recommendations 

To make sure you maximise the available promotions available at 666 Casino, follow these helpful tips. 

  • Claim Both Bonuses - In most welcome offers, the deposit bonus and free spins come hand in hand in the same bonus. However, at 666 Casino, you need to make two qualifying deposits to claim your matched deposit bonus and your free spins, so make sure you don’t miss out. 
  • Maximise Your Bonus - The minimum deposit required to claim the welcome bonus is £20, but there’s a maximum of £66 in bonus funds available, so make sure you deposit at least £66 when making your first deposit. 
  • Plan Your Gaming - The bonus funds must be used within 21 days of being credited to your account; otherwise, they’ll expire. So, make sure you give yourself plenty of time to use your bonus funds after claiming your bonus.

Registration & Banking

We can tell you’re all raring to go and claim that 666 Casino welcome bonus, but before you do, you need to create an account and make your first deposit, so let’s take a look at how you do just that.

Create an Account

The first thing you need to do if you want to enjoy everything 666 Casino has to offer is create an account. Creating an account at 666 Casino is simple, and it won’t take you long to get your account set up and ready for your first deposit. We’ve created a step-by-step guide that will walk you through setting up an account at 666 Casino. 

  • Click the red “Join” button on the top right-hand side of the page, or click the red “Join Here” button in the middle of the homepage. 
  • Enter your email address, then create a username and password for your account. 
  • Enter your full name, select your gender, and then select your date of birth. 
  • Choose your preferred currency, then enter your home address and mobile number. 
  • Enter any bonus codes you’ve been given and select your marketing preferences. 
  • Tick the box to accept the terms and conditions of the site and acknowledge that you’re at least 18 years old. 
  • Click the green “Open Account” button. 

It’s just that easy - after following these instructions, you’ll have your very own 666 Casino account.


After you’ve set up your account, the next step you need to take is making your first deposit. You have plenty of payment options available at 666 Casino, so no matter how you like to make online payments, you’ll likely find your preferred payment method here. 

However, you’ll find that there are fees applied to both deposits and withdrawals at 666 Casino, depending on the payment method you use. All payment methods are subject to a roughly 2.5% withdrawal fee, and on top of that, PayPal deposits incur a 3.1% deposit fee, and Visa/Mastercard deposits incur a 2.5% fee. 

To help decipher the deposit options available at 666 Casino, we’ve created a helpful table with all the information you need.

Tips & Recommendations 

To ensure that your sign up and banking experience is as pain-free as possible, make sure you follow these helpful tips.

  • Always Use Your Real Information - It’s imperative that you use your correct personal information when creating your online casino account. Any account made fraudulently will be closed by the casino, and any funds in the account may be seized.
  • Avoid Using PayPal or Visa - Both PayPal and Visa incur deposit fees as well as withdrawal fees, so we’d recommend against using them for your casino banking.
  • Only Withdraw When Necessary - The roughly 2.5% withdrawal fee will start to hurt if you’re making frequent withdrawals, so we recommend only withdrawing when absolutely necessary to avoid being hit by fees.

Whether you enjoy playing state-of-the-art online slots or classic casino games such as online roulette, you’ll find it here at 666 Casino. Let’s take a closer look at the most popular games available on the site.

  • Online Slots - 666 Casino has an extensive library of quality online slots available, with over 1500 unique titles to play. The site has a number of exciting video slots, jackpot slots, and Drops & Wins slots to choose from, including popular titles like Sweet Bonanza, Wolf Gold, and Wild West Gold.

Playing for Fun or Real Money 

One thing that all casino players must decide after signing up for a new casino site is whether they’re going to play for fun or real money. Many online casinos offer both options, but the majority of players only play for real money. Deciding which one to choose is important, as there are risks that come with playing for real money. 

When you play for real money, every action you make will either win or lose you money. If you make a bet and win, you’ll win real money that you can withdraw and spend elsewhere. However, if you make a bet and lose, you’ll lose real money. There’s a real risk that you walk away with less money than you started with when playing online casino games for real money, which is why we always encourage our readers to gamble responsibly. 

On the other hand, playing for fun comes with no risks whatsoever. The money used to play these games is not real, meaning that any losses you incur do not affect you financially. However, that also means that any wins you enjoy will not result in you winning real money. We recommend that beginners start by playing for fun and only move to real money games once they fully understand how to play the games they’re interested in. 

Software Providers 

One thing we always try to highlight in these reviews is just how important it is for an online casino to offer games from a number of different software providers. The more game providers a casino has, the more variety you see in the games, which makes for a better gaming experience. 

666 gambling casino has over 25 different game providers on the site, with many of them well-known for creating some of the best casino games on the market. Companies such as Microgaming, iSfotBet, and Evolution Gaming are industry leaders in the online casino game market, so you can be sure that there are hundreds of quality games available to play. 

666 Casino Mobile App

Rather than spend the resources developing a dedicated mobile app, 666 Casino has instead focused its attention on creating a mobile-optimised website. This has the added benefit of being able to be played from any device without the need for a bulky download. All you have to do is browse the site from a modern web browser, log in with your 666 Casino details, and you’ll have access to hundreds of quality casino games. 

Once you log on, you’ll find the site has been well-optimised for the smaller screen. Everything is clearly readable, all the images look fantastic despite being compressed, and it’s easy to find all the games. You still have access to all of the tabs you’d have on the desktop site, so finding your favourite game only takes a couple of taps. Fans of mobile gaming could do a lot worse than the mobile site at 666 Casino.

Safety, Security, Licensing, and Regulations

Player safety is our number one priority when creating these reviews - we will never recommend a site we believe to be unsafe, and we endeavour to only recommend the very best sites to our readers. To ensure that we only recommend the safest sites, we have a team of experts examine the licensing status, player safety, and security measures in place at each casino. Let’s take a look at what our experts found when they examined 666 Casino.

  • Licensing - 666 Casino has a licence to operate in the UK, given to them by the UK Gambling Commission. The UKGC is one of the world’s premier gambling authorities, thanks to its strict requirements and harsh penalties for misuse. A licence from the UKGC shows that 666 Casino is a fully above-board site that’s safe for UK players.
  • Player Safety - There is a dedicated responsible gambling page at Casino 666 which provides plenty of support to players who suffer from problem gambling. There are links to resources where players can seek further assistance for their issues, as well as a number of tools in place to help control your gambling, including deposit limits, time outs, and self-exclusion.
  • Security - Data security is a priority at 66 Casino, and they have a number of security measures in place to ensure your data remains secure. These include using 128-bit SSL encryption for all connections to the site and using the latest in firewall technology. 666 Casino will also never share your personal information with other organisations for commercial purposes. 


The reason we and so many other casino review sites place such a high importance on a site having a licence from a recognised gambling authority is because of what that licence represents. To be given a casino licence from an authority such as the UKGC, a site needs to be audited by an independent team of experts. These experts will check for a number of things, including the fairness of the RNG, the data security features, and the player security measures, just to name a few. 

A site will only be given a licence if they pass the stringent requirements set by the UKGC, so a site with one of these licences has shown that they offer fair online casino games. Plus, any site with a UKGC licence must continue to uphold these standards while they hold a valid licence, so you can be sure that any site with this licence offers a safe and secure place to play. 

666 Casino Customer Support

On top of knowing that your data will be secure, you also need to know that you’ll be looked after if you have any problems or queries. 666 Casino has two ways to contact the customer support team - via email or via the live chat function. 
The live chat function is by far the best way to get hold of the 666 Casino customer support team. You’re often connected to a member of the team in just a minute or two, and we always found them to be extremely helpful with any question or query we had. 
The other way to contact the team is via email, which can be done by completing the form on the “Contact Us” page. This will send an email directly to the customer support team, who will then reply using the email address associated with your account. We only recommend using this method if your query isn’t urgent, as it often takes a few hours to hear back from the email team. 
Both the email team and the live chat team are available between the hours of 8am and midnight CET, 7 days a week.
