666 Casino at a Glance


When you first visit 666 Casino, the general theme is that of the devil. In fact, the featured image is a man dressed as the devil advertising the welcome package. If you scroll further down, the site is packed with an avalanche of games, ranging from the latest slots to table games and a live casino.

In the top navigation bar, you’re able to filter the gaming type; popular, new, live, slots, Megaways, roulette, blackjack etc. Just underneath you can pick a particular theme of the game e.g. Egypt or your favourite game developer.

Then it’s all the games, neatly organised into a grid format. It starts off with the most popular games on the platform namely; Book of Dead, Starburst and Big Bass Bonanza.

If you are looking for further information head into the footer of the site. There, you’ll find the help centre, responsible gambling tools, FAQs and pretty much everything about the platform.

Make a deal with the devil by claiming the 666 Casino welcome offer!

666 Casino Welcome Bonus Offer


All brand-new UK players automatically qualify for the welcome offer, which is in two parts. First, you can claim a 100% matched casino bonus of up to £66 on your initial deposit. The minimum amount is £20, and once claimed, you have 21 days to use the bonus credits.

On your second deposit (minimum £20) you’ll be rewarded 66 free spins on the Big Bass Bonanza slot. Once you’ve been credited the free spins you only have 24 hours to use them.

For the £66 in bonus credits, you cannot use it on all games. For instance, Video Poker, Roulette, Quick Play, Hi Lo Fever, Baccarat & 3 Card Poker are all disqualified from the promotion.

How to Sign Up & Claim Your Welcome Bonus

  1. Click on the red “JOIN” button in the top right corner
  2. Input your personal and contact information and choose a username
  3. Upload identification and proof of address documents
  4. Make a minimum deposit of £20 and you’ll get a 100% matched bonus of up to £66
  5. Make a second deposit of £20 and get 66 free spins on Big Bass Bonanza

Wagering Requirements

Before you claim the welcome package, read the terms and conditions of the deal first. One of the major conditions of the promotion is that there is no 666 Casino no deposit bonus. Both the matched bonus and free spins require a deposit of at least £20.

You must also take into account the wagering requirements too. This is a number and it means how many times you must play through the funds to be able to make a real money withdrawal. In the 666 Casino bonus, the wagering requirements are 35x so if you make the minimum deposit of £20, you will need to make £700s worth of wagers. You can win or lose on these bets but you must meet the 35x number first.

One more thing to consider with the 66 free spins promotion is the maximum amount you can win is £100. However, on the matched bonus there is no maximum amount you can withdraw.

Welcome Bonus Terms

  • On your first deposit, you can claim a matched bonus of up to £66
  • On your second deposit, you are rewarded with 66 free spins on Big Bass Bonanza
  • For both deposits, the minimum deposit is £20
  • There is no 666 Casino no deposit bonus
  • Wagering requirements are 35x

Additional Bonus Offers & Promotions

Drop & Wins

The Pragmatic Play promotion is available to play at 666 Casino. It’s a point-based system on selected slots where up to £2m in prizes is up for grabs every month. Just play any game with a Drop & Wins icon in the top right corner and play real money games. From there, collect points and climb the leaderboards. The top prize at the end of the month is a cool £20,000.

Does 666 Casino have Special Promos or Reward Programs?


Once again, when we put together this 666 Casino review, we could not find any special promos or reward programmes for UK players. This is rather disappointing, but if there are any reward or VIP programmes we will be the first to let you know.

How is the Game Selection at 666 Casino?


The game selection at 666 Casino is massive, to say the least. You have 1,500+ games to play including a vast array of online slots, classic table games and an excellent live casino section.

Besides the classic casino games, you can play instant wins games such as scratchcards. Or, if you’re looking for something unique, you are able to play Slingo, a hybrid between slots and bingo.

If you’re looking for the thrill of a real-life casino, then the live casino allows you to play everything from table games such as blackjack and exciting game shows.

What Game Developers does 666 Casino have?

When we wrote our 666 Casino review, we found 20+ game developers that supply the platform. Finding all the software providers is simple, in the navigation bar at the top, you can filter between them, so if you have a favourite, it’s easy to see the games.

We think the number of game developers at 666 Casino is impressive, and it compromises top names such as Yggdrasil, NetEnt and Play’n GO. Yet, if you’re looking for smaller, independent studios, you can choose brands like Wazdan, Ruby Play and Atomic Slot Lab.

Online Slots Overview

If you love spinning the reels, then 666 Casino will be right up your alley. You can play over 1200 slots, including video slots, classics, 3D slots and even Megaways. What’s more, you’re able to use the filters to select the theme of the slot you want to play. These range from animals and ancients to movies, fruits and more!

If you’re looking to play the most popular slots in the UK that’s an option at 666 Casino. You can try your luck at Starburst, Fire Joker or Bonanza. The cherry on the cake is that new titles are added weekly, which can be found in the “New” category in the top navigation bar.

Jackpot Slots Overview

If you want to win big off one spin, then head over to the jackpot section. There, you’re able to take your pick from Jackpot Kings titles and Wowpots where often the jackpots are in the millions.

If you’re looking for more ways to win, then try the Megaways slots on offer. You have 117,000+ ways to win, and 666 Casino offers popular UK titles such as Bison Rising Megaways and Rainbow Riches Megaways.

Table Games Overview

There is no dedicated table games section at 666 Casino, instead, you have to pick which type of game you want to play. The options include all the classics namely; blackjack, roulette and other games, where you can play baccarat, video poker and dice games.

In the roulette section, there are European and American versions to play, as well as the popular 20p Roulette, made by Inspired Gaming. If you prefer blackjack, there are plenty of variants to try from classic versions to Single Deck Blackjack.

Live Casino Overview

In the live casino section of 666 Casino, there are 100+ live games to play. These range from exciting gameshows to classic table games such as baccarat, blackjack and roulette.

Many of the games are supplied by Evolution Gaming, an industry leader. When you play any game, each one is hosted by a friendly dealer and live-streamed from an authentic studio. On many of the titles, stakes start from as little as 50p, but for high rollers, you can wager £5k per game.

Banking & Payment Options at 666 Casino


When writing this 666 Casino review, we found nine payment methods for deposits and eight for withdrawals. This is a fair number to get you started and the banking options comprise debit cards, e-wallets and Trustly and PayPal.

In fact, the methods you have at your disposal are Visa/Mastercard and e-wallets. These include UK casino payment methods MuchBetter, Skrill, Neteller, Astro Pay, ecoPayz and Paysafecard. Finally, online solutions such as Trustly and PayPal are accepted. Notably, digital cards like Apple Pay and Google Pay cannot be used to make deposits and withdrawals.

Making a deposit is simple, and to claim the welcome offer you must deposit at least £20. Just head over to the cashier section in your account, select your preferred payment method, input the amount and hit confirm.

Deposits, Withdrawals & Payout Speed

When you make deposits and withdrawals, you can transact in pounds sterling and you will not be charged a processing fee for either. The minimum deposit on every method is £10, but to qualify for the welcome package you must deposit at least £20.

When it comes to withdrawing your winnings, the times vary depending on which banking method you use. Firstly, all withdrawals may take up to five days to process by the 666 Casino team. From there, getting your winnings will differ on which banking option you use.

Debit cards take around 3 – 5 working days, whereas e-wallets like Skrill, Neteller, MuchBetter and ecoPayz will take 0 -2 days. For PayPal, and Trustly expect to get your funds in 0 – 4 days, and finally, Astro Pay will take 3 days to get your money. Notably, you cannot withdraw with Paysafecard.

KYC Process & Documents

  • Upon registration, you are required to upload identification and proof of address documents
  • One is to upload a copy of your passport, driving licence or ID card
  • The other is to upload a recent bank statement or utility bill
  • To make a real money withdrawal, these documents must be uploaded
  • If you need any help, you can contact customer support

Customer Support at 666 Casino


We asked some questions to customer support prior to writing this 666 Casino review. The first was about the withdrawals and the second one was about ongoing promotions. We asked these questions on the contact form and got a response in under 2 hours.

We thought the answers were professional and helpful, but we are slightly disappointed that a contact form is the only option. There is no phone support or live chat, which may prove annoying especially when it comes to claiming bonuses when you’re signed up.

666 Casino Mobile Compatibility


If you prefer playing blackjack or online slots on the go, then you can play in your mobile browser. Unfortunately, we couldn’t find any native apps for Android or iOS, but mobile browsers offer you a great experience.

This is because the game selection is identical to that of the website. That means you can play all the most popular slots and live dealer games all on your smartphone. Moreover, you can even deposit and withdraw in the mobile browser, as well as claim bonuses.

When you play in a mobile browser the game quality is top-notch, and you’ll never experience lags. This is all possible because of state-of-the-art HTML5 technology.

Player Safety & Responsible Gambling


666 Casino does a sterling job at keeping UK players safe when it comes to responsible gambling. The dedicated page can be found in the footer of the site, and you’ll find helpful information on staying in control. Furthermore, there are questionnaires, information on restricting minors and links to third parties such as Gamblers Anonymous.

In your 666 Casino account, you’re able to set daily, weekly or monthly limits as well as take cooling-off periods. In addition, you can request reality checks and if you’re experiencing issues it’s possible to self-exclude. Everything can be done via your account without the need to contact customer support.

Licenses & Security


When you are playing casino games at 666 Casino everything is above board. That is because it is regulated and licenced by the United Kingdom Gambling Commission (UKGC).

666 Casino Verdict


There it is, our in-depth 666 Casino review! What do we think of the platform? First, we are big fans of the two-part bonus, although the minimum deposit is on the steep side.

Yet, the banking options at your disposal are extensive, and the number of games you can play is off the charts. The quality of the gaming selection is something to shout about too, as you can play the most popular UK slots and exciting live dealer games.
