In this 666 Casino Review, you will find information about the software providers that are available in the casino and the slot games that you can choose from. You will get a full explanation of the welcome bonus, its terms and conditions, along with the spins that come with it. You will get detailed information on the jackpot games, table games, and the live casino section. We won’t miss mentioning the available payment methods and what customer support options you have in order to be well informed while playing.

Before you move on, it’s worth mentioning that playing at 666 Casino is safe. It is licensed by the UK Gambling Commission, so be sure that any regulations and requirements concerning players’ safety and security are met. Also, players are asked to provide full information and documents to verify their account for any fraud to be avoided. And the information is being protected according to all standards. The casino also pays serious attention to preventing the risk of gambling, providing its players with the options to set deposit limits, time reminders, and other accepted tools for self-control.

Favourite Software Providers and Hot Famous Games

There is no surprise that most of the games, offered in 666 Casino, are slot games. They vary from popular classics to new hits. Among the software providers, you can find big names along with regular ones that are also well-known in the business. There are the standard table games – roulette and blackjack, but there are also some interesting variations of these, such as the Double Ball Roulette. You will also be pleased to find out other interesting table games, such as Swap the Flop and Six Shooter. There is no option to test the games for fun, but you can play right away after registering, although the account verification may take some time. Games are separated into different sections. There is also a helpful search function. You can either type the name of the game you are looking for or choose directly among certain software providers.

As we mentioned, 666 Casino relies mainly on slot games. Although their number is not so vast, compared to other operators, you can choose between more than 500 games. And the number of providers is reasonably large, including 1×2 Gaming, Ainsworth, Amatic, Authentic, Bally Wulff, Bet Digital, Betixon, Betsoft, Blueprint, Booming Games, Darwin, Evolution Gaming, Eyecon, Ezugi, Gamevy, Gaming Realms (Slingo), Gaming1, Gamomat, Green Jade, Hacksaw, Inspired, iSoftBet, Lightning Box, Microgaming, Neogames, NetEnt, NextGen Gaming, Oryx, Pariplay, PlayNGo, Playson, Playzido, Pragmatic, QuickSpin, Realistic Games, Red Tiger, RedRake, Ruby Play, Salsa, Scientific Games, Sigma Gaming, Skywind, SpinBerry, StakeLogic, SYNOT, Tom Horn, Wazdan, Yggdrasil.

No doubt that you will find some of the most favoured games. The table section delivers the standard variations of Classic Blackjack, Single Deck Blackjack, along with European, American and French Roulette. Almost all poker variants are also on your disposal. Unfortunately, loading the different sections lags a little bit and the running through games can become a bit annoying. The live dealer games in the casino are powered by NetEnt and Evolution Gaming and provide good graphics.

Slot Games Section

666 Casino offers a swide range of lot games developed by different software providers. The drop-down menu loads various options. You can play some of the top games by NetEnt, Play’n Go, Games Warehouse, ReelNRG, Games Lab, D-Тech, Microgaming and load progressive jackpot hits like Rainbow Riches or adventurous ones like Book of Dead, and the very famous Gonzo’s Quest, Aloha! Cluster Pays, Jack and the Beanstalk. It’s slot selection makes it a part of the Storm Gaming Technology online casinos suitable for new players. Anyway, most of the very best and popular games and providers are missing here, but there are plenty of others that you can choose from and test. They can also bring you very good emotions, indeed. So, don’t hesitate to try them on.

We all know the most popular slots, but here at 666 Casino, you can really enjoy some other fresh options. Navigate through the software provider menu and try them. For example, you can find suggestions from Barcrest (Lady of Avalon, Dr Jekyll goes Wild, Mighty Black Night), ELK Studios (Route 777, Ivanhoe, Wild Toro), Merkur (Eye of Horus, Magic Mirror, Double Triple Chance) and even Top Thunderkick slots as (Carnival Queen, Esqueleto Explosivo) or WMS (Amazon Queen, Black Knight). Most of the providers are represented by a few slots, but the overall list is reasonably large and something will surely grab your attention.

Roulette, Blackjack and Other Table Games

The table games section, unlike the slot games, does not provide such a great choice but is reasonable enough. Games are very easy to find on the menu and you wouldn’t wonder for a long, as their total number appears on the screen and you don’t have to scroll down too much. You can find the most popular and played variants of online casino roulette, blackjack and poker. The casino provides and other table favourites like baccarat. Also, each of them has low and high-stake variations.

In the roulette section, you will find the most popular European, French and American Roulette, but also the interesting Double Ball Roulette. There are around 4 French Roulette options with their high and low-stake versions.

The blackjack section is slightly larger, with variations going from European, Classic and Atlantic City Blackjack, to other interesting ones, such as the Single Deck and Double Exposure and Common Draw Blackjack. Here again, players can choose between high and low versions of the games, depending on their preferences.

If you had enough with the roulette and the blackjack, go to the poker section and choose between Deuces Wild, Jacks or Better, Joker Wild or Double up Poker variants. Although there are also some interesting suggestions like Fortune Pai Go and All Aces Poker, the choice seems to be poor. But if you want to play live casino poker then you can go for Texas Hold’em or Caribbean Stud Poker. The list with table games continues with baccarat or you can find some scratch card games, such as Irish Eyes 2, The Snake Charmer, both provided by NextGen, or Virtual World Cup provided by 1×2 Gaming. Other interesting suggestions from the list are the Red Dog Progressive and Swap the Flop or the Sharp Shooter and the Six Shooter. But as we stated earlier, the table portfolio of 666 Casino is not that big and cannot grab much attention with such various choice.

Live Dealer Casino and Games

As we mentioned, the list with table games is not so big. Same with the live games at 666 Casino. Not much of a choice, compared to some other rivals. With the live games by NetEnt and Evolution Gaming – roulette and blackjack are, of course, available along with live poker, Dragon Tiger or Dream Catcher. Roulette and blackjack live games provide some choice of different tables and limits, though.

Mobile Compatibility, App and Game Overview

666 Casino does not provide a dedicated mobile application for Android, iOS or Windows. The website is mobile responsive and compatible with mobile devices. When you open the 666 Casino software, it will automatically find the proper settings to adjust to your device. And you don’t need to download anything, making it easy to use just right away.

666 Casino Welcome Offer and Other Promotions

666 Casino offers an interesting welcome package for new players consisting of 6 separate deposit bonuses up to £66 each. On the first deposit, you get 100% up to £66. All the other 5 deposits will be rewarded 50% up to £66. And if this is not enough, you get a generous 66 bonus spins on Big Bass Bonanza, right after the first deposit. Players will have to wager 35 times the bonus and deposit amount.

Pay attention, though, that games contribute differently to the wagering requirements.

666 Casino Deposit and Withdrawal Оptions

As demanded by the regulatory bodies, 666 Casino is obliged to pay strict attention to players’ safety. So, presumably, depositing and withdrawing should meet all relevant security requirements. The list with available payment options includes VISA, MasterCard, PayPal, Open Banking, Trustly, MuchBetter, Skrill, PaysafeCard, Sofort, GiroPay, Neteller, ecoPayz, Euteller, Interac, Jeton, EPS, CashtoCode, NetBanking, UPI, Pago Efectivo, Directa24, WebPay, AstroPay and Boleto.

The minimum deposit in the casino is £20, and there is no maximum limit. Players should also be aware that before proceeding with any deposits, they will be asked to provide the necessary documents to verify their account and to contact the customer support to enable their deposit options further. On the cashier sections in their profile, players can see what deposit and withdraw choices they have. At 666 Casino you can also set daily, weekly or monthly deposit limits.

Withdrawal options can also be found in the cashier section of the player’s account. Have in mind that since the latest updates of the UK gambling regulations, there are no maximum or minimum withdrawal limits. However for other currencies, it is €7000 ROW, GBP, EUR, CAD, USD, NZD, ZAR, NOK, INR, CLP and SOL. The good thing is that the casino does not charge any fees for the deposits and the withdrawals, which is always a great thing for the players. Note that all withdrawals at the casino will remain in a pending period for approximately 48 hours, but over 85% of withdrawals are processed in under 8 hours.

Withdraws typically reflect within the first 3 business days but can take up to 5 business days to reflect depending on player bank’s processing facilities. The methods you can use to cash out from the casino are VISA, MasterCard, PayPal, Trustly, MuchBetter, EcoPayz, Skrill, Neteller, Wire Transfer, Directa24, NEOSURF, AstroPay Card, XanPay OlaMoney, CashtoCode eVoucher and Interac. The minimum amount you can withdraw is £10.

Customer Support Information

666 Casino offers standard customer support options. You can either contact them via e-mail or live chat. Although there is no phone available, we highly recommend the live chat. You can ask any questions and you get an answer right away. The casino agents react quickly and are helpful, proceeding politely to solving any problems that players might have. Bear in mind that live chat is only available once logged in. If your questions are not so urgent you can also use the e-mail. It might take some time to receive an answer, but it is reasonably quick.

Unfortunately, the FAQ section of the casino is very inferior. It consists only of a few questions and short answers. They are, indeed, very general and will hardly provide any useful help at all. Therefore we recommend you use the live chat as it seems to be the best way to quickly receive an answer to questions, concerning your account, bonuses, features, etc.

666 Casino – A Fresh Addition

In the end, our impressions of 666 Casino are not that bad. As we mentioned, the casino offers a wide range of software providers, thus allowing players to choose among various slots. You can either play one of the most popular games or explore others, that might give you thrills too. The slot section of the casino is the best place to stay. Although it offers one of the most popular table games and a reasonable live casino section, we think it could perform better there. If you are keener on roulette and blackjack, then we recommend you Ladbrokes Casino with its vast variety of table games. Apart from that, with its ‘hot’ atmosphere, 666 Casino may be a new fresh addition to your preferred places.
