21 Casino Sister Sites and Casino Review



21 Casino is a UKGC-licensed site that was established in 2015. It’s been running for a couple of years now. A company called White Hat Gaming is its operator. The casino also has licenses from the Swedish Gambling Authority and the MGA. Moreover, the game providers used by the site are popular names such as Microgaming, NetEnt, NYX, Big Time Gaming, Scientific, and more than a hundred in total. Overall, the site offers a variety of slots, table games, specialties, and live games. In total, the suite contains over 650 titles. 

Regarding real money play, the official currency is GBP, and the deposits/withdrawals must be carried out through the same method. Some of the banking methods are Visa, Maestro, Paysafecard, Skrill, Trustly, Neteller, PayPal, InteracOnline, and Bank Wire. Moreover, the casino has a customer support team that can be reached 24/7. For that, the options are live chat or email. However, this site is not available for players who reside in the United States. 

21 Casino Sister Casinos 

White Hat Gaming, the operator, also owns a number of 21 Casino sister sites. There are nearly 30 casino platforms with different themes and promotions. Additionally, the newest is 21 Riches, but it has yet to be launched. Here is the full list of 21 Casino sister casinos and their welcome offers: 

21 Casino Review

Firstly, this casino offers a vast and diverse range of casino games created by the industry’s top providers. In fact, the platform utilizes over 100 providers and a mix of famous names along with some newer companies. It’s quite a great starting point to get players interested. In addition, the casino holds some powerful credentials that solidify its reputation.

Our review will inspect 21 Casino in great detail and offer you our honest opinion on it. We’ll look into the casino design, platform functionality, game quality, bonuses, customer support, and more. 

First Impression

21 Casino has a sleek and classy theme that incorporates white, gold, dark grey, and black colors. The logo is a golden crown with a unique design. The site falls nothing short of spectacular at first glance. What’s more, the front page features some smooth animations and neatly designed banners. They contribute to a luxurious atmosphere. However, despite all the impressive qualities of 21 Casino that are witnessed at first sight, the interface takes a while to get used to. 

In fact, the reason for that is the lack of a conventional menu bar that enables quick navigation. 

Unfortunately, the top of the platform’s main page only has a few buttons (crown, dice, and sound icon), which are a bit misleading. Actually, they are not named and lead to the main page, game selection, and promotions. Apart from the dice symbol, it’s hard to tell which options you’re selecting. Of course, this is not an intentional issue on the casino’s part, but rather a design flaw that may confuse some players. 

The lack of a standard floating menu icon that contains buttons and links to each section of the casino is something that could potentially slow down your gaming. Moreover, the floating menu only becomes available if you move all the way to the bottom of the page, but it fails to include some essential options. Frankly, it’s a pain to navigate all the way down in order to access the most important options every time. What’s more, there is no separate Banking section on the site, and the casino seems to be missing the FAQ page. The casino definitely needs to improve on these aspects.

We felt like pointing these issues out at the beginning was crucial, as most of the other details regarding this casino seem to be top-notch.

21 Casino Details

Apart from the previously mentioned flaws, 21 seems like a solid online casino that caters towards U.K. players. As with most UKGC-licensed platforms, U.S. players are not allowed. To prevent any confusion, access to the site is conveniently restricted from the U.S. However, other regions like Sweden are allowed, as evident by the MGA and SGA license. 


Overall, the multiple licenses obtained by this casino are highly impressive and point towards a highly-reputable casino site. As mentioned, it’s something that will grab players’ attention from the get-go. And regarding the platform specs, it’s available on mobile/desktop devices. It appears that the casino offers two ways of playing, i.e., via apps or the instant-play mode. The platform has Android and iOS apps (free) in addition to a desktop app for Windows. However, if you’re not inclined to download storage-consuming apps on your devices, you can simply access the casino through your web browser. 

Moreover, the game offers by the casino are not available to non-members. This means that to access the practice mode (free-play), you’ll need to sign up. Nevertheless, the majority of game titles can be tested for free, which is a neat feature. 

So far, we dove into some of the features required to get you going should you choose to play in 21 Casino. However, what does the gambling community think of this casino? How is its reputation aside from the impressive credentials listed? 


All in all, 21 Casino has gotten substantially positive reviews from many of the top watchdog portals. In addition, we can’t seem to find any current complaints online, and it appears that that the site truly sticks to the strict and professional rules enforced by three of its licenses. The rest of the casinos by White Hat Gaming also appear to be safe and secure. 

However, there are some complaints from a few years back. Most of them were posted by players in 2017 and are related to payout and verification issues. These problems are incredibly common with most web casinos, and it appears that 21 has taken care of them as soon as they became public. Thus, there’s nothing to worry about here. Lastly, if you’re looking into this casino, bear in mind that the 21 name is quite common. Its variants are used by tons of other casinos that may not be as secure. 


As stated early on, the casino utilizes games from over a hundred providers. Some of them are Bally, Elk Studios, Barcrest, Sapphire, Realistic, Quickspin, NetEnt, Merkur, Big Time, Lightning, Play n’GO, etc. Its massive list of top names that will surely accommodate any gambler. 


Furthermore, the library is loaded with games, and if you visit the game screen, you’ll find that it’s rather easy to navigate through it. The categories are as follows: New Games, Top Games, Slot Games, Live Games, Table Games, Jackpot Slots, and Other Games. In addition, you can use the option to display games by provider. We would have liked to see some search filters for the categories, as this would facilitate quick navigation. 

In addition, it seems that the games are region-specific, so you may not see a full selection depending on your location. It also appears that the suite does not contain video poker. Overall, the suite contains around 80 table game titles and over 500 slot titles. In total, there are 30+ jackpot games and 20 live dealer titles. The Other Games section has specialties and has over ten games. 


Fans of slots will probably go for popular NetEnt titles here like Starburst. Other games include Book of Dead, Extra Chilli Megaways, Legacy of Egypt, Dead or Alive, Cashzuma, Tombstone, Donuts, etc. 

Some of the most popular titles online can be found in the library, and that includes a range of video slots along with classic and progressive. Overall, the games run smoothly, and most of them incorporate HD graphics and awesome animations. One of the things that impressed us was the fact that additional details (paylines, reels, etc.) pop up over the game logo once the player hovers over them. The RTP is shown for each game, which is a great touch. In general, the RTP is around 95% to 97% and over for the majority of 21 Casinos slots. 

And in terms of the progressive slots, you’ll be able to try some legendary titles here like Genie Jackpots, Trident, Pig Wizard, Arabian Nights, Mega Moolah Isis, etc. Some of these are among the most popular progressives online and could land you some major wins. 

Table Games


And for the table games, there are nearly 80 titles. It’s a rather large selection compared to most sites that only have around twenty or so. The titles are based on poker, blackjack, roulette, and other table games. You’ll find many variants here. For instance, the roulette games are Lightning, Noveau, Advanced Low, European, etc. The poker games are 3 Hand Hold’em, Pai Gow, Texas Hold’em, etc. There are quite a lot of blackjack variants, including Single Deck, Double Exposure, Player’s Choice, and more. 

Other Games

This section contains specialty games, and most of them are scratchcards. The titles here are Fishin’ Frenzy, Lucky Gems, Genie Wild, Panda Mania, and more. In addition, you’ll find 1x2gaming’s Virtual World Cup and Soccer titles here.

Live Dealer Games

Lastly, 20 live titles are available, including Blackjack, Baccarat, Carribean Stud, and Hold’em. There are a few special titles such as Dragon Tiger, Deal or No Deal, Football Studio, and Monopoly Live. The practice mode will not be offered on the live casino games, though. 


As stated earlier, the lack of a Banking page could cause some problems here. The only information regarding finances is offered in the terms and conditions. The bottom of the casino page simply shows the logos of some available banking methods. As stated in the rules, withdrawals and deposits are carried out with the same method. 

For deposit and withdrawals, the options are Visa, Maestro, Paysafecard, Skrill, Trustly, Neteller, PayPal, InteracOnline, and Bank Wire. In addition, it may be possible to make payments via SMS. The minimum for a deposit is £10, while the max withdrawal sum is 

£25,000 (weekly). The smallest sum that can be paid out is £10. As outlined in the terms, it takes no longer than three business days to complete a withdrawal, excluding the verification period that can last no more than two days. 


It seems that 21 prefers to keep it simple with their bonuses, and there are only four programs for new and existing players. 

Firstly, the welcome offer consists of a unique 121% match that goes up to £300. Plus, those who claim this offer will get 21 FS on the iconic Book of Dead slot. The promo includes an obligatory 35x playthrough (deposit as well as bonus). It can be activated with a £10 deposit. It’s also possible that this casino awards no-deposit bonuses, but their availability may vary. 

The other promos are a reload bonus offer (21%) and a weekend bonus that could get you up to 50 FS depending on the deposit size. Moreover, the site has a loyalty program that offers around two points per each £10 deposit. Depending on the number of collected points, players can gain additional bonuses. 


Upon inspecting the site’s reputation, we didn’t notice any complaints related to the CS team. As mentioned, the main contact option is the live chat. Alternatively, players can use email. The team appears to be active 24/7. However, a phone option is not offered. Nevertheless, the chat function is open for guests and not just registered players, which is a useful option. To test the service, we asked some questions about the game range. It took a couple of moments until the question was answered, and the rep was quite polite and well-versed in the casino’s games. 

Final Thoughts

All in all, 21 Casino boasts some impressive gambling credentials, a diverse game range, top-notch providers, and experienced customer support. We struggled a bit with the user interface as some key sections and options are missing, though. Still, the casino’s reputation appears to be flawless. If you’re based in an accepted country, 21 Casino could be the ideal option!
