In this review, we will tell you about the welcome package at 666 Casino, what are the terms and conditions of each of the 6 deposits of the welcome offer, and how to get the free spins on the first deposit. You will also learn about the other available casino promotions and their terms and conditions as well. We will not forget to inform you about the payment methods that you can use and how to make a deposit or a withdraw. And last but not least, a few words will be given about the casino’s loyalty program.

The Welcome Package

Although 666 Casino doesn’t offer any deposit bonus on registration, the welcome package at 666 Casino is great. Not only is it by the casino’s devilish theme, but it also consists of 6 consequent deposits. Claiming the bonus is fairly easy. Create your account and deposit at least £20. Then you can qualify for a 100% bonus up to £66 on your first deposit, and also, 66 free spins on Book of Dead video slot will be added to your account. The other deposits – from the 2nd to the 6th, are 50% bonus up to £66. That makes a £396 in total for your first 6 deposits.

Welcome Offer
  • Welcome Bonus: £66
  • Wagering: 35x
  • Min. Deposit: £20
  • Validity: 30 Days
£66 + 66 Free Spins
Full T&Cs apply. Full T&Cs apply. 18+. New players only. One bonus offer per player. Min deposit £20 Max bonus bet £5 Bonus offer must be used within 30 days and bonus spins within 10 days, otherwise any unused shall be removed. Bonus funds are 100% of your first deposit up to £66 plus 66 bonus spins on Book of Dead slot only, and 50% of deposits 2-6 (incl) up to £66 Bonus spins winnings are credited as casino bonus and are capped at £50 Bonus funds are separate to Cash funds and are subject to 35x wagering the total of bonus plus cash. Only bonus funds count towards wagering req. Terms apply. BeGambleAware.org

The deposit + bonus funds are subject to 35x wagering requirement. Any unused (i.e. not wagered) bonus funds within 30 days will be removed from your account. The minimum withdrawal from your cash funds is £20. There are no deposit methods excluded for this offer, so players can choose their preferred payment method and claim the bonus right away. That’s a great thing, taking into account the fact that for many of the competitors’ offers specific payment methods are often not eligible for the welcome bonuses.

Right after you make your first deposit 66 free spins will be credited to your account. They will be available for the Book of Dead video slot, giving you the chance to make a good start before you proceed with the other deposits. You have ten days to use the spins. Otherwise, they will be removed from your account. Have in mind though, that winnings from the spins are credited in the form of casino bonus and are kept at £50. To turn these bonus funds into cash funds, you have to wager 35 times the value of the bonus amount plus your original cash deposit.

Other Casino Offers

666 Casino is entirely oriented to those players who prefer casino games and the fact that there are only casino promotions certainly proves that. Some of the visitors, though, might be disappointed a little bit if they are looking for a bunch of interesting promotions with the intent to win some instant prizes. What you can find at the casino is three additional weekly reloads that can give you the chance to get another bonus. And these offers are quite similar, thus decreasing the chance of grabbing your attention or giving you greater playing experience. Despite that fact, they don’t have any hard conditions, and you can still enjoy them. Don’t be frustrated as there is also a loyalty program, and if you are a VIP player, you can receive exclusive offers. That certainly is a great advantage.

The other three offers that are available at the casino are the ‘Manic Monday’, the ‘Wednesday’s Slice’ and the ‘Weekend Prep’. They are weekly reloading bonuses available for existing customers, and you can choose all three of them or only the one you prefer. But let us tell you a bit more about them. With the first one – the ‘Manic Monday’, you can get a 10% match bonus up to £50 every Monday. With the ’Wednesday’s Slice’, you get 25% match bonus up to £50 in the middle of the week, and with the ‘Weekend Prep’ – a 25% match bonus up to £50 on your first deposit on Friday. As you can see, you have the chance to play and receive an additional bonus every single week.

The terms and conditions for each of the weekly reload bonuses are quite the same. There is a 35x wagering requirement on the value of the bonus plus the deposit amount. All unused bonuses shall be removed from the player’s account if unused (i.e. wagered) within 30 days. A minimum deposit of £20 is required, and the minimum withdrawal from your cash funds is also £20.

The Loyalty Program at 666 Casino

Another interesting feature of 666 Casino is the loyalty program. New players who make their first deposit will receive immediately 500 loyalty points to have a good start. Also, for every £10 wagered players will receive a certain amount of points depending on the type of casino game they play – 0.25 points for the roulette, 0.5 points for the blackjack, 2 points for the scratchcards and slot games, and 1 point for the Video Poker. For every 1000 loyalty points, players can get £5 bonus money to play with.

Are There Other Offers at 666 Casino?

666 Casino is entirely dedicated to those who love casino games. There is a poker section indeed that holds a set of popular poker variant, but there are no dedicated poker bonuses or poker tournaments. The welcome offer at 666 Casino is quite attractive, and the other three weekly reloads can surely give you an additional delight. The loyalty program, however, could be better developed as we think it rewards you with a rather average amount of points and you have to earn too many of them to get some cash that worths it.

Bonuses to Avoid

The available bonuses at 666 casino – the welcome package and the three reload bonuses, have very similar requirements. Some skilled player may find this rather boring and unattractive, while others might be more happy about it. As the terms and conditions of the offers are quite similar and not too harsh to meet, we can hardly recommend a better one, or at least we can not give you a piece of advice which one to avoid. It is all up to you to decide which one you want to use.

Deposits and Withdrawals

At 666 Casino, you can deposit via one of the most widely used payment methods – Visa, Mastercard, Skrill, Neteller, PayPal, Paysafecard and others. First of all, we have to ensure you that depositing at 666 Casino is safe and secure. The UK Gambling Commission regulates it. That means that all the necessary safety requirements are strictly applied. Players must only use payment methods registered in their name to make a deposit. The minimum deposit amount at the casino is £20, and there is no maximum limit.

  • Visa
  • MasterCard
  • PaySafeCard
  • Skrill
  • Neteller
  • PayPal
  • Bank Transfer

The minimum withdrawal amount at the casino is also £20. Have in mind, though, that you may not proceed with any withdrawal until you thoroughly verify your account by providing the necessary documents. Withdrawals will be paid back to the same payment method used to deposit the account. Once a withdrawal is requested it will take two business days for the withdrawal to be accepted. You have to be patient as the necessary delay is due to the verification of your account and additional security measures.

Steps to Withdraw

Requesting a withdrawal at 666 Casino should not be a difficulty for you. Once you have fully verified your account by providing the necessary documents, there are several steps that you have to follow. We have described them for you in the table below to have a piece of useful information in advance.

  • Step 5: Wait until you receive the money There is an additional verification period of 2 business days. After that, the money should be transferred to your account, and you will be able to withdraw.

Expired Offers

The only outdated promotion at 666 Casino that we could find on the internet was the previous welcome package that was available at the casino some time ago. We have described it in the table below so you can see the differences between the old offer and the current one.

Outdated Bonus Type Offer Conditions Max. Win Was Valid Until

Bonus funds are separate to Cash funds and are subject to 35x wagering the total of bonus plus cash. Only bonus funds count towards wagering required. Full T&C Apply. £666 N/A

As you can see, the outdated offer was similar to the new one. However, the amount of the bonuses and the number of reloads in the welcome package were different while the wagering requirements were almost the same. We can state that 666 Casino does not change the overall outlook of its bonuses too much.

What Can We Say About 666 Casino

We think that the casino lovers will be interested in the promotions at 666 Casino. The welcome package along with the available offers for existing customers can please everyone who is looking for good bonuses. You don’t need to use bonus codes at 666 Casino. The terms and conditions are not harsh, standard we might say compared to other promotions that are offered in competitor casinos.

Welcome Bonus £66
Loyalty program 1 available
Other Promotions 3 available
All Offers 4 available

The loyalty program also gives you an additional chance to win some cash by earning points. However, some of the more skilled casino players would rather prefer a bigger set of ongoing offers. Unfortunately, 666 Casino lacks a bit of creativity if we are talking about promotions diversity. In the end, it’s up to every player’s preferences, whether he or she will like 666 Casino. It has an amusing and exciting devilish theme, it gives you free spins on the first deposit to better enjoy your playing experience, and 500 points to have a good start. So you’d better try the promotions at the casino and then you will see that despite the similarities that they have you can still have a great time.

Questions Regarding 666 Casino

There are always some uncertainties when you try the services of a casino for the first time. And if you are a newly registered player, there are probably some common things that you want to know. Below, we have given short answers to the frequently asked questions regarding 666 Casino. Have a look at them and maybe you will find the information you need in advance, instead of wasting time while scrolling the full terms and conditions list at the casino.

🎮 Why I Can’t Play a Game, Although I Have Bonus Money in My Account

Although you have bonus money in your account, when you try and play a specific game, it may say that you can’t, due to insufficient cash in your account. The reason for this is the fact that the bonus money can only be used in certain games – and these are precisely slots and scratch cards.

💸 Why Is My Withdrawal Still Pending?

There is an indeterminate period of 2 business days, once you have requested a withdrawal. This procedure is required due to further verification and security check. Once this 2-day period has passed, the withdrawal will be accepted.

🔑 What Should I Do If I Forget My Password?

There is a ‘Forgot Your Password?’ pop-up link on the ‘Login’ section. Click on this link and follow the instructions to see how you can change your password. The new password will be validated immediately, and you will be able to access your account.
