21 Casino Review

About This Site

21 is another in the long line of top-class UK slot sites delivered by the White Hat Gaming group. Those who read The Slot Buzz regularly will know how highly we rate these casinos. They offer a huge selection of slots from well over 50 game suppliers including all our favorites, and usually tempt you through the door with highly competitive bonus offers. Other casinos on this label include Casilando, Jonny Jackpot and Fruity Casa. If you’ve played at any of those then you’ll know what to expect here. The crew behind 21 Casino have created a classy-looking site which bestows the image of a high roller brand, with gold and black lettering and the iconic roulette wheel adoring the home page. This says it’s not just slots fanatics who are welcome here, the door is open to table game players too with a wide choice of live dealer action to choose from as well.

If you decide to register with 21 Casino you’ll be eligible for an on-brand 121% match up to £300 – a pretty competitive offer – and deposit with a range of popular payment services, including Paypal and Applepay alongside traditional debit cards. This all comes with the backing of Malta Gaming Authority and UK Gambling Commission licensing, both of which uphold high standards of security, safety and fairness for gamblers.

In short, there is a lot to like here. You can sign up and claim that 121% match bonus right now, or read on for our full review, including a profile of the games and software, the bonus program and much more.

Games and Software

The stand-out feature of 21 Casino is their game catalogue. This is a monster selection of slots, table games and live dealers. We are told there are more than 1,200 to choose from in total, all accessible using a very clear and easy to use menu system that facilitates filtering by game supplier and game name to make it easy to jump straight to the slot of your choice. Hit the games button in the menu bar, then the Providers link to see a full list of studios. This impressive selection includes big names like NetEnt, Microgaming and Big Time Gaming alongside awesome new ones like Nolimit City. So for example, right now you can spin the reels on titles like the mind-boggling San Quentin xWays, Push Gaming’s Fat Rabbit, Play n Go’s latest Reactoonz adventure, Reactoonz 2, BTG’s Megaquads grid slot, and all of Barcrest’s iconic Rainbow Riches titles. That’s just a very tiny selection of what’s on offer. And it doesn’t matter whether you are a high variance freak of someone looking for some casual spins on low variance slots like Starburst, you’ll be catered for here.

21 Casino has a traditional feel so it’s no surprise that they also offer a wide choice of classic table games too. These can be played in the old RNG (Random Number Generator) format, or in the live dealer format with live feeds of real croupiers dealing cards and spinning the reels from game studios worldwide. The live tables here are streamed by Evolution Gaming and offer classic versions of Blackjack and Roulette alongside exclusive ones like Lighting Roulette and Infinite Blackjack. There are also Gameshow games to try too, with glitzy themes and charismatic presenters spinning the wheel in Crazy Time and Dream Catcher. These are lighter and more easy to play than traditional table games and suit the slots players out there.

Bonuses and Promotions

The simple but generous bonus for new players at 21 Casino is a 121% match of up to £300. You’ll need deposit a minimum of £10 to trigger the deal and keep in mind that the bonus itself comes with a 35x wagering requirement. That means you will need to wager the bonus value 35x or more before it is converted into cash. If you do not complete this within 30 days then you will forfeit the bonus.

These are all pretty standard terms when it comes to casino bonuses and overall it is a good offer with a good maximum bonus value. It is unusual to exclude any free spins from an offer like this and it’s a shame you can’t grab some free play on the slots here. However, once you are a regular depositor at 21 Casino you will be given the chance to grab free spins in weekly offers and as part of the ‘Royal Loyalty’ program. This is the 21 Casino loyalty club where you can earn points for all your wagering and convert those points into bonuses and spins. Overall, White Hat Gaming sites are known for their generous rewards progams and experience shows that you will be well-looked after at this site.

Cashier and Payments

At 21 Casino the cashier process is robust and efficient providing quick deposits and withdrawals across a wide range of popular payment services. This includes debit cards Visa and Mastercard – note from spring 2020 credit cards were banned from online gambling sites in the UK. Deposits can also be made through popular eWallet options including Paypal, Neteller and Skrill. The advantage of virtual wallets is the withdrawal times. If you withdraw to Paypal for example your funds will show instantly on your balance after 21 have processed the payment. Normal bank payments may take up to 5 working days. You can find out more about this in our Paypal slots guide.

Note that the minimum deposit and withdrawals at 21 Casino are £10 and withdrawals will be processed in under 24 hours.

If you want to record the conversation you have with a support agent then we recommend using email. This can come in handy if you enter into a dispute over your account or the games at any time.
