666 Casino Bonuses & Review

Are you looking to ‘relight your fire'? That's the slogan of 666 Casino, a popular, devil-themed online gambling site, launched in 2017. 

There are lots of ways this online casino helps set your soul on fire - from a quirky welcome bonus (up to €66 in bonus cash and 66 free spins) to a strong user experience, and of course a great selection of games. 

666 Casino at a Glance 

666 Casino Overview 

666 Casino is themed around a playful devil character, so while it might seem a bit sinister at first, you’ll soon see that this is a light-hearted online casino that takes fun seriously. What impressed us most about 666 was the range of over 1,500 different games, ranging from newly released slots to casino classics in the live dealer environment. 

You’ll have the chance to earn rewards when you deposit and wager, and you can redeem these for bonuses, which is a great way to try out some games that you might not have played otherwise. To get you off to the best possible start, 666 Casino has an attractive welcome offer of a 100% match up to €66 plus 66 free spins. 

666 Casino Welcome Bonus 

The 666 Casino welcome bonus is unique. Most other Irish online casinos award a 100% match up to about €100 or €200 and a few free spins, but 666 Casino sticks to the theme right from the start. You’ll get a first deposit match up to €66, plus your welcome package includes 66 free spins to get you started in a devilishly good way. Here’s how it works:

• First deposit: Matched bonus of 100% up to €66
• Second deposit: 66 free spins on Big Bass Bonanza

Don’t forget to check the T&Cs thoroughly before you sign up and deposit to claim your offer. There’s nothing here that you wouldn’t have seen if you’ve signed up at other online slot sites before, but the main terms are still worth noting. 

• Available to all new Ireland players age 18+
• A minimum deposit of €20 is required to claim each offer.
• 35x wagering applies.
• Wagering requirements must be met within 21 days.
• Free spins expire after 24 hours.
• Maximum win of €100 from free spins.
• Please gamble responsibly.

666 Casino Bonuses 

666 Casino has some online casino bonuses and offers available, which you can find on the promotions page when you’re logged in, but they’re not as regular or varied as those of some other online casinos. Nevertheless, it’s a good idea to check the promos page every time you log in so that if any special offers come up, you’ll see them immediately. You can also sign up to the marketing emails from 666 Casino to receive all the latest bonuses and offers.

One promotion that 666 Casino runs regularly is the Pragmatic Play Drops & Wins offer, which runs across all Pragmatic Play online casinos on a linked network. There are some seriously huge prizes available. For example, there are up to €2,000,000 in prizes across the course of a month. You don’t have to be super lucky to win one of these, as the prize money is spread out to make tonnes of smaller prizes, and these can be awarded randomly on any spin on a participating Pragmatic Play game. 

A major reason why 666 Casino might not always have loads of bonuses is because players can earn points and redeem them for bonus money, so what you get is largely based on how much you play. Players who wager a lot will be able to claim up to about €100 per month in bonuses if they have enough points. 

Online Slots at 666 Casino

666 Casino is home to over 1,500 different games, and the vast majority of these are slots. The 666 Casino lobby is laid out in an interactive way, where all the latest and best games are surfaced at the top of the page so you can explore easily. 

Not all online casinos have the option in the lobby to filter the games by provider and theme, but both are available at 666 Casino. Some of the games to try including are “fish” games (a very specific theme indeed) like Fishin’ Pots of Gold, Fisherman’s Bounty, and Fishin’ Frenzy; jewel-themed games like Perfect Gems and Deco Diamonds Deluxe; and big adventures like Jolly Roger and Legacy of Dead.

We always look out for games with special features when we’re reviewing online casinos, and there are two that stand out here: Megaways and Drops & Wins. Megaways games work with a special mechanism that changes up the number of symbols that land on each reel every time you spin. This makes for thrilling gameplay and results in hundreds of thousands of ways to win. Drops & Wins is less of a feature and more of a promo, but it’s still an excellent reason to play on a certain slot game - you’ll have a chance to win a random cash prize with every spin.

If you like the sound of a random cash prize, you’ll probably be interested in jackpot games too. 666 Casino has an entire section in the lobby for jackpot games and some of the biggest progressives like Thunder Struck II Mega Moolah are available. There’s also a good selection of Jackpot King slots like King Kong Cash and Crabbin’ for Cash Extra Big Splash, which hold their own jackpot prizes. 

New slot games are added to the 666 Casino library all the time, and when we logged on for the first time, we saw five brand-new games added that very day. Some of the top new titles to explore include Gold Blitz Extreme, 2 Wild 2 Die, and Syn’s Fortune. 

If you prefer to stick to what you know and love, you won’t be disappointed by the fan favourites that you can find at 666 Casino. These include Big Bass Bonanza, Book of Dead, Wolf Gold, Fire Joker, and Starburst. 

666 Live Casino 

There are over 150 live dealer tables for you to try at 666 Casino, and they’re diverse, so no matter what type of games you prefer, you're almost guaranteed to find them here. 

As is the case at all of the best live dealer casinos, classic games are always popular, and many people decide to stick with options they know, like blackjack, roulette, and baccarat, but in our opinion, this is a mistake, because there’s so much more out there. We’d recommend heading straight to the gameshows section to try out Mega Ball, Monopoly Live, or Dead or No Deal. 

If you prefer to stick to card and table games, you can enjoy options like Three Card Poker, Casino Hold’Em, Lightning Roulette, Instant Roulette, Free Bet Blackjack, Power Blackjack, and a whole lot more. If you want to try the live casino experience without any other people. opt for one of the “First Person” games that uses animation to create the live dealer effect. 

Placing your bet on any of the live casino games is straightforward, and you don't need to have any experience in casino games to give it a try. The live dealer will guide you through the process and tell you when it's time to bet and you can communicate with them directly using the chat function on the screen. The live dealer games at 666 Casino create that social feeling of being in a land-based casino but with the added convenience of being able to enjoy the games from home. 

666 Casino Software Providers 

666 Casino carries games from about 50 different providers, so there’s no shortage of variety. Depending on what you prefer, you can choose to play games from providers that concentrate more on special features or select ones that have big progressive jackpots. Some of the best casino software providers here include Pragmatic Play and NetEnt, but there are a whole lot of others too. 

It’s worth calling out Games Global, as their progressive jackpot games in the Mega Moolah series can hold huge payouts of up to seven figures. For games that are more innovative and jam-packed with features and new ways to win, Pragmatic is a good option. 

In the live casino, tables from Evolution Gaming are a must, but that’s not to say that we don’t recommend trying out games from other providers like Stakelogic, which often have games that the main providers don’t, and the tables might be a bit quieter for a more low-key experience. 

666 Casino Payment Methods

Irish players can make use of some of the most convenient online casino payment methods to deposit at 666 Casino, and of course, all these methods are safe and secure. 

Most people choose to deposit using their bank card (Visa or Mastercard), but you can also use Instant Banking, Skrill, Neteller, Paysafecard, MuchBetter, or Payz. All your deposits should reach your online casino account immediately, so you can get started with playing all of your favourite games.

You can withdraw to all the same methods except for Paysafecard, and the withdrawal time will depend on your method. While 666 Casino tends to process withdrawals almost instantly, it’s then over to your payment provider, and this may take up to six days in the case of bank cards. 

E-wallets tend to be much quicker, and you’ll usually only wait about two days for your money. Be aware that in most cases you’ll need to withdraw using the method that you’ve previously used to make a deposit.  

666 Mobile Casino

Like most new online casinos, 666 has decided not to develop a mobile app, but rather a responsive mobile website that adapts for your specific screen size, whether you’re using an iOS or Android mobile device. 

The 666 mobile site is just as easy to navigate as the desktop version. We were happy to see that all the filtering options (including by theme and by provider) were available in the games lobby, each slot is represented by a large, visual icon, so you can get a preview immediately. 

The gameplay is also just as good, even if you’re playing live dealer games. If you’ve never played on mobile, you’ll find that tapping your screen rather than clicking like on a desktop is intuitive. You can also deposit, withdraw, and claim promos from the mobile site.
