21 Casino at a Glance


The homepage of 21 Casino is organised into segments, with the top one being a slideshow featuring the 121% welcome bonus, safer gambling tools and top games. Just below, you’ll see the most popular video slots in the UK such as Book of Dead and Bigg Bass Bonanza. 

Further down the page is the Live Casino segment. This showcases six of the best live dealer games, including Monopoly Live, Lightning Roulette and Blackjack Live. The final category is the New Games, which are predominantly slots. We found new titles added every week, too. 

Finally, in the footer area of the site, you’ll find some important information like the live chat, promotions, terms and conditions and the privacy policy. Overall, a simple but effective design!

Grab a decent welcome bonus and explore more than 2,000 games at 21 Casino

21 Casino Welcome Bonus Offer 


All brand-new UK players are eligible for the 121% matched bonus at 21 Casino. To qualify, the minimum to deposit is £10, whereas the maximum is £100. This means that, if you deposit £10, you’ll get £11.20 in bonus credits. And, if you deposit £100, you’ll receive £121 in bonus funds. 

To claim, you just need to register for an account and make a deposit between £10 and £100. From there, the bonus credits will be automatically applied to your account. Notably, the 21 Casino 50 free spins promotion on the Narco’s slot has expired, but the 121% welcome package should be enough to get you started. 

Once you’ve claimed the deal, you have 30 days to spend the bonus credits. And the good news is that all deposit methods are accepted for the promotion. Awesome!

How to Sign Up & Claim Your Welcome Bonus

  1. Click the gold “SIGN UP” button in the top right
  2. Fill in your personal and contact information 
  3. Upload a copy of your passport or driving licence
  4. Make a minimum deposit of £10 – or more
  5. The bonus funds will be automatically applied 

Wagering Requirements

Before you claim the 21 Casino welcome bonus, you must understand the wagering requirements and gaming contributions. Fortunately, our experts have done all the hard work for you in this 21 Casino review. 

The wagering requirements are 35x, which is in line with the industry average. It’s worth noting, however, that bonus funds are only applicable to selected games, with some counting higher than others. To give you an idea, most slots count 100%, scratchcards and keno are 100%, table games 10% and video poker 5%. For any other game, the bonus credits do not count.

Welcome Bonus Terms

  • The 21 Casino welcome bonus is automatically applied 
  • The minimum welcome bonus deposit is £10
  • The maximum is £100 for the promotion 
  • The wagering requirements are 35x the bonus
  • Most slots contribute 100% to the bonus funds 
  • Once claimed, you have 30 days to use the bonus

Additional Bonus Offers & Promotions

At the time of writing our 21 Casino review, we could not find any other promotions. This is a surprise as we expect ongoing bonuses for loyal players. However, if there are any promotions, we will be the first to let you know!

Does 21 Casino have Special Promos or Reward Programs?


There is no VIP or reward programme to speak of for UK players. 21 Casino did have a loyalty programme called Royal Loyalty Points. However, this was stopped in October 2021. If another 21 Casino reward programme pops up in the future, check our page for any information on it!

How is the Game Selection at 21 Casino?


You can enjoy 2,000+ games at 21 Casino UK. This includes the most popular slots in the UK, as well as a vast array of traditional games. You can play the big three (blackjack, roulette or poker) or baccarat, game shows or dice games in the dedicated Table Games section. 

There is also a huge collection of jackpot slots, where you can win big just off one spin. Yet, if you’re looking for something more authentic, the 21 Casino live area offers UK players a first-rate gaming experience. Furthermore, you can also enjoy less popular games. These include scratchcards, Slingo and craps, with 50+ variants to try in the Other Games category. 

What Game Developers does 21 Casino have?

While writing our 21 Casino review, finding the list of game developers was a piece of cake. In fact, on the navigation bar you can select “providers” and more than 50 will appear. These range from huge names like Evolution Gaming to smaller indie gaming studios such as Wazdan. 

Having more than 50 providers is a massive number for any online casino. It will give you a vast amount of choices when selecting a game to play. To help you out on that front, whenever you hover over a game, it will give you a brief intro and details about the developer that made it. 

In the 21 Casino live section, the games are supplied by Evolution Gaming, Pragmatic Play Live and Ezugi, three titans in the industry. You’ll enjoy a real-life experience from an impressive studio hosted by professional live dealers.

Online Slots Overview

You are spoilt for choice when it comes to 21 Casino slots. There are 1,500+ titles to choose from. Take your pick from popular UK slots, video slots, Megaways, Cluster Pays, sticky wilds and more! 

To help you further in picking a slot game to play, when you hover over a title with your mouse you can see the volatility, reels, win lines and the game developer details. Nice! 

You’ll be happy to hear you can also play the UK’s favourite slots too. We’re talking Starburst, Book of Dead and Gonzo’s Gold, to name but a few. Yet, if you are looking for something brand new, slots are added weekly in the appropriately named “new” section. 

Jackpot Slots Overview

Perhaps you are looking to strike it rich with just one spin? If so, head over to the jackpot slots category at 21 Casino and take your pick from 200+ jackpot slots. The cherry on the cake is the Drops & Wins slots that give you the chance of winning a share of £2 million-plus every month. Just keep an eye out for Pragmatic Play’s Drops & Wins icon on each eligible slot machine.

If you want to play the Blueprint Gaming Jackpot Kings series, where the grand prizes are regularly also in excess of £2 million, then you can feast on plenty of titles at 21 Casino. The most popular ones in our opinion are Bison Rising, King Kong Cash and 7s Deluxe. 

Table Games Overview

The table games section is packed with classic games and some unique variants to try. In total, there are 90+ games on offer, including roulette, blackjack, baccarat, craps, game shows and dice games. The games are supplied by software powerhouses such as Relax Gaming, Golden Rock Studios and Switch Studios. You can even see the volatility of games before playing. 

Besides classics, you should try unique twists on games like blackjack and roulette. For example, if you’re a beginner, check out 10p Roulette by Gamevy. Or if you want to try your luck at getting closest to 21, then have a go at Blackjack Xchange made by Slingo Originals. 

Live Casino Overview

If you want to experience the thrill of a real-life casino from the comfort of your own home, then 21 Casino Live is ideal! In this section, you can play traditional live casino games such as baccarat, blackjack, roulette or poker. Or, if you prefer something different, you can play game shows such as Crazy Time, or even try your hand at the super fun Football Studio. 

Most of the games are made by the industry leader Evolution Gaming and are live-streamed from top-class studios hosted by friendly dealers. Yet, you’ll also find live games supplied by Pragmatic Play Live, namely Speed Baccarat and Indian Roulette.

Banking & Payment Options at 21 Casino


While doing research for our 21 Casino review, finding the payment methods was not as simple as we would’ve hoped. In the end, we had to contact the live chat for answers. Admittedly, there are logos of payment methods at the footer of the site. But, we wanted detailed information about what banking options are available to UK players, as well as limits and withdrawal times.

Fortunately, we got this information. In total, there are eight UK payment methods available. This is not too shabby a number. There are debit cards, bank transfers and plenty of eWallets. 

Mainstream options like Visa, Mastercard and Maestro are at your disposal, as well as bank transfers. If you choose eWallets, you can transact with Skrill, Neteller, MuchBetter and Paysafecard. Notably, PayPal, Apple Pay and Google Pay are not accepted at 21 Casino UK. 

Deposits, Withdrawals & Payout Speed

You’re able to transact in pounds sterling with all payment methods. And the minimum deposit and withdrawal amount is a very reasonable £10. Plus, you will not be charged a fee by 21 Casino for any transaction you make. Also, you can make deposits and withdrawals with every method – except Paysafecard, which doesn’t allow online casino withdrawals. 

The 21 Casino withdrawal times vary depending on which method you opt for. The fastest way to get your winnings is with eWallets, where you’ll receive your funds in 0-2 days. With debit cards and bank transfers, you can expect to wait 1-5 business days to get your money. 

When you go to make a withdrawal, make sure it is to the same method you made the deposit with. This way, the process will be much faster, and you will not be asked to send in further financial documents proving that you own the payment methods. 

KYC Process & Documents

  • To oblige with UK law, you must send ID documents to 21 Casino when you register
  • These include a valid ID such as a copy of your passport, ID card or driving licence 
  • You will also have to verify your address with a recent bank statement or utility bill
  • You can upload it yourself when you register or send it to the 21 customer support 
  • Once the documents are sent, you may have to wait up to 24 hours for approval

Customer Support at 21 Casino


We tested the customer support for ourselves before putting together our 21 Casino review. Overall, the options are good, as the platform offers 24/7 live chat and an email address to get in touch with the team. Then again, the help centre is non-existent, as there is only a terms and conditions page with further information. This needs to be improved!

When we messaged customer support via live chat, we asked a question about the banking methods. The team was fast to respond but could only redirect us to the terms and conditions page. This was slightly disappointing, to say the least. 

However, we asked the same questions via email and the response we got was much more comprehensive, covering the available methods, limits and withdrawal times. We got a reply to our email in 24 hours. So, if you are looking for more information, email is a better service. 

21 Casino Mobile Compatibility


Our experts checked on the Google Play Store and the Apple App Store but could not find a native app for 21 Casino. Yet, if you still want to play on your smartphone, you can play in your mobile browser of choice.

The game selection is the same as the desktop version of the site, and the load time is just as fast, too. In fact, everything is optimised to your screen size, so you can register, make a deposit and play your favourite games all on your phone. 

If you ever have a problem, you’re also able to take advantage of the 24/7 live chat on your mobile device. Just click the chat icon, fill in your details and you’ll be connected with an agent in minutes. Excellent!

Player Safety & Responsible Gambling


Responsible gambling is a subject which is taken very seriously at 21 Casino UK. You can find further information in the footer of the site by clicking the “Responsible Gambling” link. There, you’ll find a trove of information, such as questionnaires, sound advice and links to third parties such as Gambling Therapy, GamBan and GamBlock. 

On the responsible gambling page, there are also links to set limits, whether deposits, net loss, or session time. Everything can be done via your account settings, so you can set daily, weekly or monthly deposit limits with just a few taps. Moreover, if you wish to take a time out or self-exclude, you can do this via your account without the need to contact customer support. 

Licences & Security


When you play games at 21 Casino, safety is virtually guaranteed. The platform is licensed and regulated by the United Kingdom Gambling Commission (UKGC) under account number 52894.

When a casino is licenced by the UKGC, it must adhere to strict financial and operational regulations. In addition, if you ever have an issue such as not receiving your winnings, you can contact the UKGC for free, impartial advice. 

To keep you safe whilst you’re playing, 21 Casino uses SSL encryption technology. This tech secures your personal and financial information, so malicious third parties cannot access it.
