About This Site

21 Casino is a first-class slots destination from a big player in the European online casino industry: White Hat Gaming. White Hat are responsible for a number of really nifty slot sites and casinos, including Casilando, Skol Casino and Fruity Casa. 21 has been in operation since 2015 and offers a typically diverse range of online slots, RNG table games and a live dealer suite. For video slots fans there is a big range of titles from the very best in the industry including Big Time Gaming, NetEnt and Microgaming. So whether you are a high risk Megaways™ fanatic or a casual slots player, there is something here for you.

21 Casino is licensed by the UK Gambling Commission and the Malta Gaming Authority to ensure the safe, secure and fair gaming. It offers a wide choice of payment methods, including Paypal, and if you want to dive in then you’ll be rewarded with a 121% match on your first deposit.

Sounds good, right? You can get started now or read on to find out a little bit more about this superb slots destination.


Bonuses and Promotions

On their slick home page 21 Casino are offering you a 121% match bonus with your first deposit, up to a maximum of £300. To quality for this offer you’ll need to put in a minimum of £10 and wager through your bonus funds 35x before they, and any winnings, are withdrawable. Bear in mind that you have 30 days to use your bonus, so don’t dally around or you’ll miss out!

This is a pretty decent welcome offer and goes a little above the standard 100% we see regularly elsewhere. It’s also notable for a competitive 35x WR. It’s suited to those who like to keep their gaming simple and easy without a complicated 3 or 4 tier bonus set. However, it is smaller than some other welcome packages currently on the market and if you are looking for something bigger then you could try another White Hat site like Dream Vegas where £4,000 in bonuses can be claimed over four deposits.

On top of the welcome bonus package 21 are also offering a range of regular promotions to keep existing customers on the tables and at the reels. There are some nice spins offers – you’ll often see the chance to claim 20 spins for a £10 deposit all weekend, or balance super-chargers at the start of the week where you can get 20% or more added on when you make a deposit. The promos here change from month to month so keep your eyes out to see what’s coming up.

Slot Game and Software

As part of the White Hat stable of sites, 21 Casino can treat players to a massive catalogue of slots. The slick site on desktop and mobile allows you to easily scroll through titles from a diverse range of developers. Top of the list for many players will be NetEnt of course, whose suite of games includes some stone-cold classics like Dead or Alive, Gonzo’s Quest and Starburst, as well as more recent titles like Ozzy Osbourne slot. High risk fanatics can get their latest fix from titles in the Megaways™ series and from Big Time Gaming. If high variance is your thing then don’t miss out on some heart-stopping fun in Lil Devil, Bonanza, and Danger! High Voltage.

For more quirky titles our recommendation is to load up some of the games by Swedish masters, Thunderkick. Their Pink Elephants I and II are a genius take on the 4,096 ways to win slot format, and they’ve also delivered many more highly original games for all types of player. Highlights include Birds on a Wire, Fruit Warp and Flame Busters. Elsewhere you can dig into slots by Nolimit City, WMS, Barcrest, Push Gaming, Red Tiger and a load more. In fact, pretty much any and every slots studio is represented here – so whatever your tastes, you’ll get on well at 21 Casino.

Look out too for the the brand new slots that are on release each month – 21 Casino features lots of these, many of which you’ll find profiled on our own slot review pages – recent titles like Codex of Fortune from NetEnt or Wild Flower from Big Time Gaming are worth a spin.

Cashier Options

Another advantage of spending your money with a big player like White Hat is that you get a reliable cashier and payment service featuring a wide choice of deposit options. You also get fast withdrawals, and a 24-hour support team on hand to answer any queries that you have about your account or the games you play.

Whilst in the UK credit cards are no longer permitted, debit cards are. So here you can deposit to your bank account with Visa, Mastercard and Maestro. Meanwhile, those who prefer to use an eWallet solution can pay by Paypal, Neteller or Skrill. It is also possible to use Trustly and Paysafecard.

There is a minimum deposit of £10 at 21 Casino, which is pretty standard, and withdrawals are processed within 24 hours. That means eWallet players will get their funds on the same day on most occasions. Debit card users will have to wait for the bank to do their bit, which can take up to 5 working days. 

If you’ve got a support query then you can contact the team via email or live chat. Our only gripe about 21 Casino is that there is no phone option available
