21 Casino Review

21 Casino is operated by White Hat Gaming and launched in 2015. The UK Gambling Commission and Malta Gaming Authority license the casino.

Set against a black and grey background, emblazoned with gold and white text, 21 Casino has a sophisticated look and feel. With a photo of a lady wearing a telephone headset, accompanied by the text ‘Always first-class customer service! Need Help? Chat Now!’ you get the impression this online casino is more serious about providing good customer service and care compared to many of its competitors.

There are many games at 21 Casino from top software providers such as NetEnt, 1x2 Gaming, Microgaming, Push Gaming and Barcrest. The number increases all the time, and what we like about White Hat casino sites is that they feature games from up-and-coming game providers.

But what about the nitty-gritty of the site? What games does it offer?


From Starburst to Wild West, Rich Wild and the Book of the Dead, and Medusa 2 to Neon Staxx, 21 Casino has a favourable mix of games ranging from all the old favourites to some great new ones. There are many slot games available to play on 21 Casino, some of which are jackpot slots, offering extremely enticing six-figure prizes. For example, hit the jackpot on Mega Fortune, and you could get your hands on a cool £4.5 million, a figure that’s rising every second! Or why not test your luck on Mega Joker and bag a rather handy £15,000 in the process?

Like all White Hat Gaming slot sites, 21 Casino has hundreds of slots available from hundreds of game software providers, so it's a huge plus.

Table games

There are plenty of table games available to play on 21 Casino, including Baccarat, Caribbean Stud, Oasis Poker Pro, Sharp Shooter, and Six Shooter, amongst others.

Live Games

There are also several live games available to join in on 21 Casino, including Blackjack, Common Draw Blackjack, Automatic Roulette, Roulette and VIP Roulette. It isn't the biggest or best live casino offering around, but most of us are happy enough with the selection.


Poker enthusiasts will be in their element on this casino site, as it offers a handful of poker games, including All American DBL UP, Deuces Wild DBL UP, Jacks or Better DBL UP, and Joker Wild DBL UP.


If you want to play your favourite games whilst you’re out and about, on 21 Casino, you can, as the site has a mobile version. Its mobile page lists all the games you can play from a mobile device and includes a range of top games, two table games – Blackjack and roulette – and a myriad of slot games. The mobile version of the casino runs extremely quickly and seamlessly.

Deposit and withdrawal methods

21 Casino offers a great number of deposit and withdrawal payment methods, including- PayPal, Maestro, MasterCard, Neteller, Bank Wire Transfer, Boku, Sofort, Finnish Bank, Skrill, Paysafe Card, Trustly, Visa, Entropay and Interac.

Withdrawal limits are set at a reasonable €25,000 per week, subject to ID checks as expected at any casino.

A long-established casino site

Another favourable feature of 21 Casino is that it has operated since 2015. Unlike the large number of casino and bingo sites that seem to appear daily, 21 Casino has lasted the test of time, which consequently gives us confidence that it is a reputable, honest, quality and valued member of the increasingly congested online casino marketplace.

Safety First

The fact it advocates safety also fills us with confidence to ‘put our money where our mouth is’ and play games on this site. From using the latest online technology to ensure members’ details are kept safe to being secured by the ‘strongest SSL encryption available’, 21 Casino assure that it is a wholly safe and secure casino website. 

21 Casino, along with all of the White Hat Gaming casino sites, is an approved donor of Bet Blocker, a tool that can be installed on your devices to help with any problem gambling. You choose your own 'time out' period and are blocked until the period lapses.
