21 Casino Review

The Casino remembers fondly when he turned 21. He had a big party with all the other gorillas in the jungle coming along to celebrate. If only he could relive it once more. The Casino Gorilla loves 21 Casino because it reminds him of his fantastic birthday party and it’s classy with lots to offer, just like him.

  • Impressive number of online slots
  • Classy, stylish design
  • 24/7 customer support
  • Weekly reload bonuses and bonus spins
  • Loyalty scheme with plenty of rewards
  • No VIP club
  • No phone number provided

21 Casino Bonus

If you decide to sign up to 21 Casino, you’ll be handsomely rewarded for doing so. The casino’s welcome offer for new players gives you the following:

  • 121% match bonus of up to £300

You can claim this bonus when you make your very first real-money deposit. Thanks to this offer, you can get your 21 Casino experience off to a great start, with quite a lot of bonus money up for grabs. Spend your bonus money on some of the casino’s games and even though you’re technically playing for free, you can still win real money.

21 Casino Bonus Spins

Bonus spins let you spin slots for no extra cost, and yet you can still win actual money. At the 21 Casino there’s the chance to win some bonus spins every weekend thanks to the Stairway Bonus. Every Friday, Saturday and Sunday, your first deposit of the day can earn you bonus spins. The more you deposit, the more spins you’ll earn:

  • Deposit £20 for 10 bonus spins
  • Deposit £50 for 25 bonus spins
  • Deposit £100 for 50 bonus spins

You can therefore be entitled to 150 bonus spins every weekend if you deposit enough money into your 21 Casino account. The bonus spins from the Stairway Bonus promotion can only be used on the following slots:

  • Stickers
  • Starburst
  • Fruit Shop
  • Aloha! Cluster Pays

21 Casino Bonus Code

Bonus codes are short codes made up of a combination of numbers or letters, or both in some cases. Some casinos require you to enter a code to qualify for a bonus. At 21 Casino, however, none of the current promotions require bonus codes of any kind.

Bonus Terms and Conditions

  • Must be 18 or older
  • New players only
  • First deposit must be of at least £10
  • £5 max bet with bonus money
  • Bonus funds must be used within 30 days
  • Only bonus funds count towards wagering requirements
  • Wagering requirements are 35x your bonus

21 Casino Slot Games

If you’re the type of casino player who likes being spoiled for choice, you’ll definitely want to check out 21 Casino. Here there’s a very large and diverse collection of slots waiting to be played – in fact, there are more than 850 of them available. The collection offers something for everyone and there are so many slots to choose from, that you might not know where to begin. If you find yourself stuck for choice, check out some of the most popular slots at 21 Casino, which include the following:

Some of the most popular slots
  • Extra Chilli Megaways
  • Starburst
  • Immortal Romance
  • Raging Rhino
  • Donuts
  • Gonzo’s Quest
  • Sparks
  • Esqueleto Mariachi
  • Dead Or Alive
  • Jungle Spirit: Call of the Wild

You’ll find all of these slots and more in the Top Games category. Head over to the New Games category and play some of the most recently released slots, such as Cosmic Jewels, Tractor Beam, Golden Leprechaun Megaways and Tweet Heart. Since the slots collection is so large, there are filters available to help you find particular slots more easily. You can sort the collection by alphabetical or reverse alphabetical order; you can also filter by most popular or provider – there are more than 80 providers that supply 21 Casino with its games. There’s also the option to have the RTP for the slots displayed.

21 Casino also has its fair share of progressive jackpots. These play just like normal slots except that there’s a special jackpot that grows in size every time someone places a bet – it keeps on growing until a very lucky player wins it. Have a spin of progressive jackpot slots such as Divine Fortune, Hall of Gods, Mega Moolah and Treasure Nile – the chances of winning are slim, but you’ve got to be in it to win it.

Live Games

With live dealer games, you can take part in real-life casino games without having to leave the house. 21 Casino offers a good line-up of live games for you to play. The options available cover classic table and card games such as:

  • roulette
  • baccarat
  • blackjack
  • casino hold’em
  • three card poker
  • and more

Mobile Gaming

If you have a smartphone or tablet, you’ll be able to access 21 Casino’s mobile casino and play lots of casino games while you’re on the go. The mobile casino is designed to be user friendly and touchscreen compatible. It has hundreds of games to offer, though note that not all of the games available on the desktop casino are available on mobile devices. This is because not all games have had touchscreen versions made just. Still, at 21 Casino’s mobile casino you’ll find more than enough top-quality games that will keep you entertained when you’re out and about. So long as your device has a steady internet connection, you can enjoy a smooth, hassle-free mobile gambling experience with the mobile casino.


Around half a dozen payment methods are accepted for deposits and withdrawals at 21 Casino. The options available include:

Payment Methods:

  • Visa
  • Mastercard
  • Maestro
  • Neteller
  • Skrill
  • Trustly
  • Paysafecard

The minimum amount for deposits and withdrawals is £10. It takes the casino around 24 hours or so to process withdrawal requests. If you’re using an e-wallet, your money should reach you as soon as the withdrawal request has been processed. For other types of payment method, you’ll have to wait a few working days.

Security and Fairness

The 21 Casino is managed by an established casino company called White Hat Gaming Limited. This company has gambling licences from three organisations:

  • the Malta Gaming Authority
  • the UK Gambling Commission
  • the Swedish Gambling Authority

This is a clear sign that the casino is trustworthy and reliable. The casino uses the latest, most advanced SSL encryption technology to ensure that everything is fully protected at all times. A random number generator is used to keep the outcomes of all games fair and unbiased, so that no player has an advantage over any other.

Customer Support

If there’s any issue of any kind or there’s something you need help with, don’t hesitate to get in touch with 21 Casino’s customer support team. They can be reached by email or through the live chat feature you can access once you’re logged into your account. Customer support is conveniently available 24/7.

21 Casino Conclusion

21 Casino is an online casino by White Hat Gaming Limited that was developed by a team of gambling enthusiasts with years of industry experience among them. The ongoing aim of 21 Casino is to provide fans of casino games with a stylish and safe online environment where they can play and hopefully win. The casino ticks lots of boxes: it has a huge games collection with loads of providers contributing games, not to mention plenty of regular chances to claim bonus spins and bonus money, plus a loyalty scheme. You won’t find a VIP club here, however. On the whole, the casino is very much worth signing up to, especially if you like having so many games to play you won’t know which ones to start playing first.

There are some online casinos that the Casino Gorilla is really fond of. 21 Casino is one of them. He simply can’t get enough of it, especially since there are so many games to play. Whenever he logs in, he feels like he’s 21 all over again.

I signed up with 21 Casino to take advantage of their welcome bonus and have never looked back since. This casino is packed full of brilliant games and the more you play the more loyalty points you earn which you can then exchange for cash money. This is definitely one of the best casinos I have played with. Customer service is great and they cannot do enough for you. Plus there are lots of promotions which keep coming for regular players on the site.

Started by playing a few free games and was hooked. Got a nice welcome bonus when I made a small deposit, but I haven’t used any other bonus yet. The slots are incredible and there are always new games being added. Found it easy to access and search for games and they all play well on a PC and a mobile device.

A great place to play at if you're currently in-between casinos and need a new one. The support is something I can personally praise. Initially I had some issues with my account, but they sorted it out real quick.

Casino Gorilla

Thank you for your comment. We have heard some good things about 21 Casino's support system, mostly about how fast they solve user's issues. We hope you keep having a fun time with them.

I was looking for a place where I could gamble safely and maybe try my hand at learning how to properly play roulette and 21 casino was a godsend for that. They have a lot of live roulette games available, and they all work very well.

Casino Gorilla

Thank you for writing in. As you were looking for a place to play roulette at, 21 Casino is the perfect choice, as they have one of the best roulette sections on the market.

I love their bonuses. I’m not fond of casinos that offer little payouts to loyal members. It’s not they can’t afford on. 21 Casino gives out generous bonuses to players with little budgets, fast payouts, and has different payment methods.
