21 Casino Casino Look & Feel
4.5 /5

21 Casino favors 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. Alexandra Camelia Dedu, one of this review’s authors, allocated this section a 4.5/5 score.

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, account, balance, available promotions, and more.

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 at the bottom and is always visible. You can use the bean menu in the bottom right corner of your screen to explore other features that are not immediately visible.

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

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

Look and Feel Verdict

  • Navigation: The site is easy to navigate thanks to its simple menu
  • Loading speed: We did not discover any glitches while accessing the platform
  • Graphics & Design: Yellow, white, and black theme, with a clutter-free design
  • Overall verdict: The operator has no mobile downloadable casino applications but stands out for its modern layout and straightforward navigation.

21 Casino Slot Games
0 /5

21 Casino is a gaming platform with a mid to high range number of slot games, with over 1000 titles. You can choose whether you want to play old favorites or brand-new developed slots or even aim high and play jackpot slots. This section receives a 5/5 score.

You will find names such as 1X2 Gaming, Evolution Gaming, Microgaming, NetEnt, Real Time Gaming, Fantasma Games, Fortune Factory, and 100 others within the group of prominent software providers.

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.

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.

We also consider the level of mobile optimization, the minimum and maximum allowed bets, the number of pay lines, and the player entertainment. If you want to diversify the gameplay, you will find a similar library with MadSlot’s 1000 titles.

Slots Verdict

Criteria Slots Verdict
Slot Selection 1000 titles Very Good

21 Casino Live Casino
5 /5

21 Casino has a particular category dedicated to around 350 available live games. You can play roulette, blackjack, baccarat, craps, sic bo, and even poker. Evolution Gaming and Pragmatic Play are the two software developers that guarantee their quality. This field receives a 5/5 rating.

Though you cannot test these games with a demo play option, you can use the low minimum bets to explore the features. There are multiple varieties of each table and card version. There are few competitors with such a significant number of live titles, and one of them is Megacasino’s 350 live dealer games, which we believe are worthwhile, especially if you’re a veteran punter.

21 Casino offers safe, secure, and dependable banking methods. You can utilize bank transfers, credit and debit card payments, and even e-wallet transfers. This website is among the rarest to offer all the same deposit and withdrawal methods, receiving a 3.9/5 score.

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 sites for the many payment methods it provides. Meanwhile, you can check out other minimum deposit gaming sites for more diversity.

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

 Payments Verdict

  • Payout time: 2 days
  • Payment methods: 11 payment methods, including Visa, Mastercard, Neteller, Skrill, and Neosurf
  • Payout limits: £100000 per month – a high amount compared to other sites
  • Overall verdict: There are multiple banking options, but the operator limits monthly cashouts and processes withdrawals in 48 hours, unlike some of the fastest UK payout websites you’ll find on our list.

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 check your payment method to see whether your transaction will be subject to extra costs.

21 Casino Licensing & Security
5 /5

21 Casino is a White Hat 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. We offer our top 5/5 appreciation for its commitment to safe environment delivery.

This gaming platform prioritizes the players’ safety and comfort, which means it offers several protection tools. 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 GameStop, BeGambleAware, and GamCare, which you can take advantage of if you need to.

If you are registered to any of these programs, you cannot bet on this site. Lastly, this gaming platform contains an SSL encryption security protocol designed to protect your personal data.

21 Casino is Legit?

Our reviews aim to research gaming websites that meet our requirements regarding licensing, game selection, banking options, and security. That is why all the platforms we review are fully licensed, offer fair and quality games, provide dependable banking methods, and are secure. Since 21 Casino received the authorization for MGA and UKGC, we consider it a trustworthy and legitimate site.

21 Casino Customer Support
4.5 /5

At 21 Casino, you will find different channels available for customer service. You can message the customer support desk via live chat or the customer support email address. There is no phone assistance, which explains the 4.5/5 rate.

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 support agents.

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.

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

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 – hence the 1/5 rating.

Our Verdict

At KingCasinoBonus.uk, 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 11 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 optimization, but some gamers would have liked an easier way to play their favorite titles.


  • 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.
  • Non-stop live chat support.
  • Minimum £10 deposit and withdrawal.


  • The operator takes 2 business days to approve withdrawal requests.
  • There is no VIP club.
  • 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 comprehensive; it offers some of the most exciting blackjacks we’ve ever tried. The 350 live games come from two of the most reputable developers that ensure the quality of the titles – Evolution Gaming and Pragmatic Play.

Why Join 21 Casino?

The banking methods and the game library on this site suit every type of gambler who wants diversity and top-notch services. Probably not the best choice if you are looking for an online casino with fast and efficient customer support. Although it has live chat and email, 21 Casino does not offer telephone communication.
