Overview
21 Casino is owned and ran by White Hat Gaming Limited. This company has built a strong reputation in the online gambling industry. Moreover, it owns many other platforms, such as Jonny Jackpot, Slotnite, Playzee, and Spinland. The company’s sites are licensed and regulated by the Gambling Commission of Great Britain, the Swedish Gambling Authority, and the Malta Gaming Authority.
Since 2018, White Hat Gaming has partnered up with Kambi Group plc, a leading sports betting technology provider. Through this partnership, both companies will be able to provide full omnichannel turnkey services for websites and betting operators.
Even more, White Hat has recently signed a partnership with the leading gaming operator in North America, Penn National Gaming Inc. The NASDAQ-listed company is operating more than 41 gaming facilities across 19 US states. Together, these companies hope to “build one of the leading businesses in American sports betting and online casino”.
Registration process
Registering on 21 Casino implies acknowledging, agreeing, and declaring that the user is residing in Great Britain. So, to open an account, UK customers must follow the below steps:
- Select the Join button;
- A pop-up window will appear where punters must fill in the blanks with their email address, username, and password;
- In the next step, users must provide some personal information. For instance, full name, birthday, address, phone number and so on.
Verification
In addition to this, one must prove that he is the legal owner of a valid payment method, has no other registered accounts on this platform, and agrees with verification checks. The verification processes aim to check the users’ identity, email, age, residence, source of deposited funds, and possibly more, all following casino’s T&C and to British Laws.
To check all this information, the operator will ask members to provide a valid ID and other documents such as recent bills, payslip, etc.
Games
21 Casino is mainly offering slot games, with over 1400 titles, from classic ones to five-reel video slots. We’re sure that players will be interested in games like Mega Fortune, Legacy of Dead, Starburst, Gonzo’s Quest, or Book of Dead. Besides slots, members can play on live casino and table games. As well, choosing games like Live Roulette, Live Monopoly, Hold ’em, Blackjack, or Frech Roulette. Scratchcards and virtual soccer are also available.
Speaking of Mega Fortune, gambling enthusiasts might’ve heard that a fellow punter has recently received a jaw-dropping jackpot amounting to €2.6 million while playing this game. This comes after several six-figure jackpots paid by the popular slot game and is more than ten times higher than the previous one.
A positive point in our 21 Casino review is that you get over 100 software suppliers to choose from, with the most popular slot developers being NetEnt, Red Tiger Gaming, Microgaming, or Nolimit City. For live casino, the primary providers are Evolution Gaming and Pragmatic Play.
Navigation tips
Users who prefer playing on mobile devices may want to know that though a mobile app is not yet available, the platform is well optimized for an excellent mobile experience. Also, when using a computer to play, one may use the browser interface or install the desktop app.
Keep an eye on the Volatility and RTP indicators, as they can have a significant influence on the game’s outcome. To get these values, launch any slot and check its pay table, which contains all essential rules for safe play. Also, remember that a game’s Autoplay function has limitations, which may apply to your:
- Number of spins;
- Wager size;
- This feature is a significant tool to gamble responsibly.
21 Casino bonuses
New user who deposit will qualify for one of the few permanent 21 Casino bonuses, a welcome promotion. For the moment, members cannot benefit from other deals, except the bonus funds coming from loyalty points.
Unless the gambling operator has clearly stated otherwise bonus spins winnings are turned into bonus funds and cannot amount to more than £100. Any winnings exceeding this amount shall be removed.
Wagering
The wagering requirement for the bonus amount is 35 times the initial funds’ value. This means that an eventual offer of £10 must be played through until a total amount of £350 has been wagered. Players must only use bonus funds to meet this requirement. In addition to this, it must be granted that a bet made using a bonus fund cannot exceed £5. Staking more than this amount using bonus funds will result in loss of said funds.
Irregular play
21 Casino has zero-tolerance for members trying to take unfair advantage of promotions or the practice of irregular play. All winnings resulted from this type of activity shall be removed, and the accounts closed, including other profiles the user might hold in the casino’s network.
Loyalty
Speaking of loyalty, punters may want to know that this website is offering £1 in bonus funds for every 200 loyalty points. These points are provided for every £10 real or bonus funds wagered in the casino, the exact points amount depending on the game type.
21 Casino may also give out coupons to its members. Just a single coupon can be claimed within 24 hours, and they can’t be used while another promotion is active, unless it’s clearly stated otherwise. If a member wishes to have a deal removed, he/she can ask for removal, as long as the offer hasn’t been played at all.
Banking
Before beginning to play, punters will have to deposit at least £10 into their account, through one of the following methods: Visa Debit, PayPal, Mastercard Debit, Trustly, PaySafe Card, Skrill, Neteller, Maestro, or Bank Transfer. The user must be the legal holder of the account he/she is using. Note that credit cards are not accepted.
Withdrawals
For requesting a withdrawal, customers must access the Account tab and select the Withdraw section. After filling in the blanks with the required information, one should check out if the data has been correctly inputted. Grant that, all requests are manually reviewed by the operator staff to ensure that they are valid. As transaction options, users will receive their cashout amounts to the account they used to deposit the initial funds.
All members will have to register and play using British Pounds (GBP). Should there be applied any exchange fee or charges from the bank/alternative payment option side, 21 Casino will not be responsible.
Cashout essential rules
Withdrawals can take up to 1 or 2 business days to be reviewed, with another 2 to 5 days to be processed, depending on the banking method used.
Withdrawing funds while having an active deal will result in revoking the bonus if wagering requirements haven’t been met.
There is no cashout limit for this gaming site.
Support
Should players need, any kind of support or help from 21 Casino’s team can either send an email to [email protected] or opt for the Live Chat feature.
Both options are available 24/7, and replies can be quick, but take note that this depends on how busy the support operators are. Before writing this 21 Casino review, we have tested the Live Chat feature ourselves, and the reply came very promptly and straight to the point. The chat operators will ask UK players to provide the email address that is linked to the account or other personal information that has already been provided on sign-up or account verification.
Complaints
Most complaints are about delayed withdrawal payments and delayed account verifications. Furthermore, the only unresolved complaint is about delayed account verification. The website’s staff has responded to each of these complaints and has proceeded to solve every issue. Still, due to limited staff and lots of verification procedures involved, this kind of problems may take longer than users might expect until they get solved.
21 Casino review conclusions
To put it in fewer words, we’ll say that 21 Casino is a website for slot games enthusiasts, but also for gamblers who prefer table games or live casino games. It’s owned by a reputable company that owns many other platforms, and it’s licensed in Great Britain, Sweden, and Malta. The website is very well optimized for mobile use, and a desktop app is available for download. The users have many payment options they can use to deposit, and withdrawals will always be paid to the same account used on deposit. If the members encounter any issues or need a piece of information they’re not sure of; they can use the Live Chat or send an email to the support team, which is available 24/7. We gathered up all the essential information in this 21 Casino review so UK players can make an informed decision and gamble safely.
