How Our Experts Evaluate & Rate 21 Casino | Complete Review

In our review process, we strive to provide British players with crucial information needed to choose between gaming platforms. This review process is comprised of several optimised processes, including discovery, auditing, testing, and finally, reviewing.

We developed this technique so that the priority was placed on maintaining the quality of the iGaming industry within the United Kingdom. To achieve our goal, we analyse each platform’s game assortment and check the available providers. We prioritize top content from major studios, and tell you which NetEnt casino games pay out at the highest rate.

Once done with game portfolio checks, identity confirmation processes ensue and verifying the licenses. Mobile user-friendliness is also paramount to us. The same process was followed in regards to this 21 Casino review.

21 Casino Registration Process Preview

21 Casino Look & Feel 4.5 /5

This is a gaming website that favours the sleek, modern look, as is evident by the combination of grey and black hues that dominate the design. The white letters, which are perfectly readable, are a great way to balance the dark background.

As for the features themselves, the interface is designed to ensure most of the important tabs are at the top of your screen. This includes the game lobby, your account, your balance, the available promotions, and more.

On the other hand, at the bottom of the screen, the rest of the crucial elements, such as the live chat, the terms and conditions, the privacy policy, and others, are available.

How to Complete the 21 Casino Login Process?

  1. Access the online platform with a device that’s online.
  2. Press the Sign Up button and look for any available 21 Casino bonuses.
  3. Create a username and password and input your email address.
  4. Insert your full name and date of birth.
  5. Type in your address and postcode.
  6. Input your phone number.
  7. Finalise the registration procedure.

How to Verify 21 Casino Account?

  1. Access your account.
  2. Click on the Account tab at the top of your screen.
  3. Scroll down to the Account section and click on the Verification Procedure tab.
  4. First, click on the orange Upload button in the Proof of ID section to upload the required documents.
  5. Then, click on the orange Upload button in the Proof of Address section to upload the needed documents.

Your account should be verified in maximum 48 hours after sending the documents. Once it’s confirmed, you can go on to claim the casino first deposit bonus.

KYC Documents

  • ID card
  • Passport
  • Driver’s Licence
  • Utility bill
  • Bank statement

It is essential to make sure that the documents you upload are up-to-date and valid. These documents must match the personal information you provided during the registration process completely. Moreover, you cannot upload the same document to verify your address and identity.

How to Close 21 Casino Account?

  1. Withdraw the remaining funds from your account balance.
  2. Message customer support.
  3. Send a request saying that you want to close your account.
  4. Wait a few days for your request to be processed.

21 Casino Desktop Preview

When you access this gaming platform, you are transported to the home page, where you can find the Log In and Sign Up buttons. Furthermore, this page provides you with access to the Home, Games, and Promotions tabs. You can explore the entire gaming platform from there.

While there is no dedicated software for Desktop devices that you can download to your device, the website more than makes up for it. Thanks to its design and accessibility, you can have a fully immersed playing experience.

To make your game search easier, this gaming website has a Providers tab, which enables you to search for games that way. Furthermore, you can use the right-hand search bar to look up games by their title.

21 Casino Mobile Preview

The desktop and the mobile version of this gaming website are, in their essence, the same. You can expect to find the same colourways and design choices, and of course, the same features available.

21 Casino is better than many of our newest mobile casino sites if you want to play live dealer games on your smartphone.

The one thing that separates the mobile version is that the bar containing the key tabs is not at the top of your screen but rather at the bottom, and it is always visible. To explore other features which are not immediately visible, you can use the bean menu in the bottom right corner of your screen.

21 Casino Slot Games 5 /5

This is a gaming platform that has a mid to high range number of slot games in its selection, with over 1000 titles. You can choose whether you want to play old favourites or brand-new developed slots, or you can even opt to aim high and play jackpot slots.

Within the group of prominent software providers, you will find names such as 1X2 Gaming, Evolution Gaming, Microgaming, NetEnt, Real Time Gaming, Fantasma Games, Fortune Factory, and many others. A provider’s presence suggests you might receive bonuses that promote its games. For instance, free spins on Starburst are a great way to boost the popularity of NetEnt.

While this gaming website doesn’t allow demo play for its slots, you can learn more about each slot by hovering your cursor over a particular slot.

  1. Book of Dead
  2. Who Wants to Be a Millionaire?
  3. Wild Frames
  4. Scroll of Dead

  10. Burn Burn 7

Several factors influence our ranking of the best slot games on a particular platform. Of course, one of those factors is the return-to-player percentage, but it is certainly not the only one.

One of our primary selection criteria is how frequently you can get no deposit bonuses for a particular slot. At 21 Casino, new player promotions with Book of Dead free spins no deposit are relatively easy to come across, which explains why we ranked the game first.

We also take into consideration the level of mobile optimisation, the minimum and maximum allowed bets, the number of pay lines, and of course, the player entertainment.

Highest RTP Slots From 21 Casino

  • Happy Holidays – 96.62%
  • Wild Frames – 96.50%
  • Vikings Unleashed – 96.50%
  • Hellcatraz – 96.46%
  • Buffalo Rising – 96.43%
  • Jammin Jars 2 – 96.40%
  • Thai Flower – 96.33%
  • Hyper Gold – 96.33%
  • Rich Wilde and the Wandering City – 96.20%
  • Big Fin Bay – 96.14%

This is a player-friendly gaming website in the sense that it has an average RTP of over 96.10%, which is considered medium to high by industry standards. Overall, all slots with 96% RTP or over are considered to meet the industry average payout percentage.

The site offers safe, secure, and dependable banking methods. You can utilise bank transfers, credit and debit card payments, and even e-wallet transfers. This website is one of the rare of its kind that offers all the same deposit and withdrawal methods.

21 Casino Deposit Process

  1. Access your account.
  2. Click on the Deposit button in the upper right corner.
  3. Choose the deposit method and look for the available 21 Casino bonuses.
  4. Insert the sum you want to deposit.

  6. Your funds will appear immediately, and you can start playing.

What Is the 21 Casino Minimum Deposit?

The minimum deposit limit on this gaming platform is set at £10 for all the payment options available.

21 Casino is better than other 10 minimum deposit casinos for the many payment methods it provides.

21 Casino Withdrawal Process

  1. Access your account.
  2. Locate the Withdrawals section and click on Withdraw Now.
  3. Choose the withdrawal method.
  4. Insert the sum you wish to withdraw.
  5. Enter your payment provider details and confirm the request.
  6. Expect a processing time of around 2 days.

The withdrawal process on this platform is as simple as the deposit process, with one important difference – identity verification. Unlike the depositing process, you cannot do the withdrawal process successfully unless you first confirm your identity.

21 Casino Withdrawal Time

The average processing time on this gaming platform is around 2 days. Of course, the processing time can vary depending on multiple factors, both internal and external. In terms of internal factors, the delay can occur if you haven’t properly verified your identity or if the platform has noted some suspicious activity on your account.

Reasons for 21 Casino Payout Problems

  • Low account balance
  • Suspicious account activity
  • No identity verification
  • Issues with payment host
  • Playthrough requirements for 21 Casino bonuses haven’t been met yet

21 Casino Fees

This gaming platform doesn’t charge any withdrawal fees, regardless of the method. However, it is not responsible for any external transfer or conversion fees. In other words, you should first check your payment method to see whether your transaction will be subject to extra costs.

  • SpinYoo
  • Hello Casino
  • Barz Casino
  • Klasino

The operator behind this gaming platform is one of the more recognisable names in the iGaming industry, with nearly 30 sites in its repertoire. There may be over 2 dozen websites in the collection, but the template regarding terms and conditions, payment methods, and game availability are the same.

UK Gambling CommissionUK Gambling Commission

21 Casino is Legit?

This is a gaming platform that operates under and adheres to gaming rules issued by two different bodies of authority. The platform is licensed by the UKGC, which makes it legal and legitimate for UK players, but it is also licensed by the MGA, which provides another layer of protection.

Is 21 Casino Safe?

  • GamStop
  • BeGambleAware
  • GamCare
  • SSL certificate

This is a gaming platform that prioritises the players’ safety and comfort, which means that it offers several tools for protection. The built-in tools like reality checks, self-exclusion tools, and even account closure are all designed to protect you.

Of course, this platform is integrated with 3 different player protection programs, including GamStop, BeGambleAware, and GamCare, which you can take advantage of if you need to.

If you are registered to any of these programs, you will be unable to bet on this site. Lastly, this gaming platform contains an SSL encryption security protocol which is designed to protect your personal data. This is especially important when claiming 21 Casino bonuses.

21 Casino customer service 4.5 /5

This gaming website has 2 different channels available for customer service. You can send a message to the customer support desk via live chat or the customer support email address.

Both options are accessible through the Live Chat tab at the bottom of the screen. You could also check the FAQ section if you’d rather not directly engage with any of the support agents.

How to Contact 21 Casino?

The customer support service is available at any time of the day according to the findings of our 21 Casino review. The responses via the live chat are instant, while the responses via the following email address: [email protected] might take up to 24 hours.

How We Tested Customer Support?

While doing this 21 Casino review, we messaged the live chat with our queries regarding the existence of a mobile app, as well as the playthrough requirements of certain promotions and website security. The answers to each question were detailed, professional, and helpful.

No phone available
Live chat:
Yes, 24/7

Loyalty 1 /5

While doing this 21 Casino review, we found that this gaming platform does not have a VIP club that you can partake in.

Our Verdict

At KingCasinoBonus, we consider that one of the best advantages of 21 Casino is the payment section. Although the operator processes transactions within 48 hours, you can withdraw up to £100000 per month. Moreover, you can choose from over 10 deposit options, including Skrill, Neteller, and Visa.

At the same time, we would have preferred to see an available mobile app for a better gaming experience. The site has good mobile optimisation, but some gamers would have liked an easier way to play their favourite games.


  • Over 10 payment options, including debit cards, e-wallets, and bank transfers.
  • The maximum withdrawal limit is £100000 per month.
  • More than 1000 slots from Microgaming, NetEnt, and other reliable game developers.


  • The operator takes 2 business days to approve withdrawal requests.
  • No iOS or Android mobile apps are available.

What is 21 Casino Best For?

21 Casino is a must for those who appreciate live casinos. It is very comprehensive; it offers some of the most interesting blackjack we’ve ever tried. It also has a spectacular line-up of slots. From such prestigious software providers as NetEnt and Microgaming, it has some of the finest titles in the industry.

Why Join 21 Casino?

Probably not the best choice if you are looking for an online casino with fast and efficient customer support. Although it has live chat, 21 Casino does not offer telephone communication, and it is often overloaded. On the other hand, some users complain that it quickly blocks winning players. It is, therefore, a more casual than a professional option.
