Jack 21 Casino App

Jack21 Casino App Intro

Jack 21 Casino is a mobile-compatible gaming site run by Mountberg B.V., a company that operates under the jurisdiction of Curacao. Judging by the name, one would assume the site caters predominantly to the needs of blackjack players but this is not the case. Instead, mobile users are treated to a full-fledged casino product that comprises over 2,600 games across all imaginable categories.

Established in 2020, the mobile casino has teamed up with 37 game providers but availability depends on your country of residence. The site’s software roster includes big names like Microgaming, Pragmatic Play, Quickspin, and Betsoft. Games from up-and-coming studios like Caleta, Endorphina, Gamomat, and Fugaso have also made it to the Jack 21 library.

Our reviewers checked the App Store and Google Play but failed to find any downloadable applications for the brand. This should not dissuade you from visiting Jack 21 while on the go, though. The casino is mobile-friendly and works on all modern handheld devices via a browser-based HTML5 application. The latter offers all the functionalities of the desktop version, including an easy-to-use cashier that combines fiat payment methods and cryptocurrencies.

Jack 21 Casino App Mobile Bonuses

App Mobile BonusesAll new customers who sign up for Jack 21 accounts by filling the registration form can redeem a standard 120% welcome bonus up to $360 along with 50 free spins. Players have the option to use the bonus funds in the standard casino or in the live dealer section. The minimum required deposit for this offer is $10.

The mobile casino will transfer all bonus-related winnings to your real balance as soon as you clear the 30x wagering requirements on the deposit and bonus. As for the batch of free spins, smart device users can play them on some of the top slots from the casino’s suite, namely Quickspin’s Northern Sky, Betsoft’s The Golden Owl of Athena, and Yggdrasil’s Sahara Nights. The wins from the bonus spins have wagering requirements of 50x their value.

The maximum amount a customer can wager during free play should not exceed $5 per round, or 10% of the balance currently available in their account. Eligible customers must clear their rollover within a week or the casino will automatically void the winnings. Slots and scratchcards have a wagering contribution of 100%, while table games, live dealer games, and video poker contribute only 5%.

Additionally, the Jack 21 app offers plenty of exciting regular bonuses like the 10% cashback up to $100 available to returning customers every Wednesday. The cashback applies to the net losses players have incurred on live games and is subject to the casino’s general terms and conditions. Therefore, it has a 10x maximum withdrawal limit. Players must process a nominal deposit of $10 before they can withdraw any winnings generated through free play.

Loyal customers and high-rollers receive invitations to join the Club 21 program. They can benefit from the services of dedicated account managers, enhanced promotional offers, and faster withdrawals. Loyal players also have exclusive access to a gift shop and are eligible for surprising offers each month.

Jack 21 Casino App Mobile Banking

Casino App Mobile BankingThe Jack 21 app offers a handful of flexible payment methods you can use to transfer money to and from your casino balance as you go. These include cards by Visa and Mastercard, the e-wallets Skrill, ecoPayz, and Neteller, prepaid solutions like Neosurf and Paysafecard, Interac Online, Flexepin, AstroPay, MuchBetter, and bank transfers. Several cryptocurrencies like Bitcoin, Ethereum, and Ripple are also supported.

The minimum deposit at this mobile casino is $10 or the equivalent in the other supported currencies. In this vein, smartphone users can choose to set up their accounts in USD, EUR, RUB, CAD, BRL, AUD, and UAH. Deposits with most of the supported methods are instant.

However, the mobile casino’s general terms and conditions dictate that players must wager all deposits at least once before they can withdraw from their balance, which is something to keep in mind. Other than that, the app does not charge fees for deposit processing. You might want to check with your bank in case it imposes any additional charges as Jack 21 is not responsible for those.

As for withdrawals, you must comply with the minimum allowed limit, which is $25 or the currency equivalent. The casino will return your winnings to the same method you have used for deposits unless it does not support withdrawals. In such cases, the operator will issue the withdrawal either to an e-wallet or via a bank wire transfer.

Speaking of wire transfers, they come with higher minimum withdrawal limits of $500 ($100 for transactions within the European Union). The maximum withdrawal per transaction is $1,000. The casino reserves the right to split player winnings of up to $10,000 into weekly installments. Winnings exceeding this threshold could be split into several monthly payments. As for speed, the casino’s financial department usually processes withdrawal requests within 2 working days.

Jack 21 Casino App Mobile Games

Casino App Mobile GamesThe last thing mobile users who play at Jack 21 can complain of is the lack of betting opportunities. The mobile version of the casino features a whopping 2,600+ games created by companies with years of experience in the industry. Betsoft, Microgaming, Quickspin, Pragmatic Play, Play’n GO, Yggdrasil, and Elk Studios are only some of the examples.

Additionally, the app offers releases from various upstarts and younger companies like Kalamba, Big Time Gaming, Kiron, Nolimit City, Spinomenal, Virtual Generation, Endorphina, and Gamomat. If interested in a certain supplier, tap the provider filter and select its name from the drop-down menu. The larger portion of the Jack 21 portfolio is available for practice play.

Players can also sift the mobile catalog based on categories like Popular, Table Games, Slots, New, and Favorites. Slots comprise the most extensive category with hundreds of available options.

Mobile users who do not feel like browsing through the enormous selection should navigate to the Popular tab. There they will stumble upon sought-after releases like Northern Sky, Deadwood, Book of Merlin, Punk Rocker, Thunderstruck II, Sticky Bandits, Moon Princess, and Rise of Olympus.

Players keen on the classic fruit theme face a diverse choice with games like Fancy Fruits, Fruit Mania, Zen Fruit, Fruit Burst, and Opal Fruits. There is no designated section for jackpot games. These are regrettably all mixed with the regular slots. On a more positive note, large jackpots are indeed available in slots like Sisters of Oz, Mega Moolah, Treasure Nile, Cash Splash, Book of Atem, Wheel of Wishes, and At the Copa.

Table games are available in spades, with most of the releases being supplied by Betsoft and Microgaming. Blackjack fans face the broadest choice, with titles like Vegas Downtown Blackjack, Vegas Strip Blackjack, 21 Burn, Pontoon, Pirate 21, and Super 7 Blackjack. Other table games you can enjoy at Jack 21 as you go include No Commission Baccarat, Dragon Tiger, Zoom Roulette, Pai Gow Poker, Oasis Poker, and Sic Bo.

The Table Games section also contains several enticing video poker variants like Jacks or Better, Joker Poker, Deuces Wild, and Jackpot Poker. The bulk of the live dealer selection is courtesy of Evolution Gaming, although Vivo Gaming has also contributed. You can face the skilled dealers in games like Caribbean Stud, Immersive Roulette, Side Bet City, Blackjack Party, and No Commission Baccarat.

Jack 21 Casino App Security and Licensing

Casino App Mobile Security and LicensingWhen it comes to safety, mobile players at Jack 21 need not worry. The mobile-friendly casino has advanced encryption technology in place to make sure customers’ sensitive data is kept hidden and confidential at all times. The mobile gaming catalog is monitored for fairness. It runs on a certified random number generator that ensures the results are unbiased and cannot be manipulated in any way.

We are glad to report the Jack 21 app features an entire section dedicated to teaching players how to gamble more responsibly. There you will find links to several organizations that provide professional help to problem gamblers.

Additionally, the app enables you to set daily, weekly, and monthly limits on your deposits. Closing your account for a specific period is also an option, and so is permanently restricting yourself from Jack 21.

Mountberg B. V. operates the casino under the regulatory oversight of the Curacao authorities. Its license was issued by Antillephone Services N.V. All players are welcome to play on their portable devices as long as they are not residents of one of the restricted countries.

These include the United States, France, Curacao, and the Netherlands. If you do not see your country on the registration page, this means the casino does not accept play from where you live. You must be at least 18 years old to legally bet via the Jack 21 app.

Jack 21 Casino App Verdict

Jack 21 Casino boasts a user-friendly app that is easy to navigate despite the fact it features a whopping 2,600+ slots and table games.

The abundance of bonuses is another plus here, and so is the fast and hassle-free withdrawal process. We look forward to Jack 21 introducing native iOS and Android apps in the future.
