Jack 21 Casino is a mobile-compatible gaming site operated by Mountberg B.V., a company licensed in Curaçao. Judging by the name, one might assume the site caters predominantly to blackjack players, but that is not the case. Instead, mobile users are treated to a full-fledged casino product that comprises more than 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 industry leaders like Microgaming, Pragmatic Play, Quickspin, and Betsoft. Games from emerging studios such as Caleta, Endorphina, Gamomat, and Fugaso have also made it to the Jack 21 library.
Our reviewers checked the App Store and Google Play, but they 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 functionality of the desktop version, including an easy-to-use cashier that supports both fiat payment methods and cryptocurrencies.

Jack 21 Casino App Mobile Bonuses
All new customers who sign up for Jack 21 accounts by filling out the registration form can redeem a standard 120% welcome bonus of up to $360 along with 50 free spins. Players can use the bonus funds in either the standard casino or 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, mobile users can play them on some of the top slots in the casino’s suite, namely Quickspin’s Northern Sky, Betsoft’s The Golden Owl of Athena, and Yggdrasil’s Sahara Nights. The winnings from the bonus spins carry wagering requirements of 50x their value.
The maximum amount a customer can wager during free play must not exceed $5 per round or 10% of the balance currently available in their account, whichever is lower. Eligible customers must meet their rollover within one week, or the casino will automatically void the winnings. Slots and scratch cards contribute 100% toward wagering, while table games, live dealer games, and video poker contribute only 5%.
Additionally, the Jack 21 app offers plenty of regular bonuses, such as 10% cashback up to $100 for returning customers every Wednesday. The cashback applies to net losses incurred on live games and is subject to the casino’s general terms and conditions. Consequently, it is capped at a 10x maximum withdrawal limit. Players must make 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. Members benefit from dedicated account managers, enhanced promotional offers, and faster withdrawals. They also gain exclusive access to a gift shop and are eligible for surprise offers each month.
Jack 21 Casino App Mobile Banking
The Jack 21 app offers a range of flexible payment methods you can use to transfer money to and from your casino balance on the go. These include Visa and Mastercard cards, the e-wallets Skrill, ecoPayz, and Neteller, prepaid solutions such as Neosurf and Paysafecard, Interac Online, Flexepin, AstroPay, MuchBetter, and bank transfers. Several cryptocurrencies, including Bitcoin, Ethereum, and Ripple, are also supported.
The minimum deposit at this mobile casino is $10, or the equivalent in any of the supported currencies. Accordingly, smartphone users can 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 state that players must wager all deposits at least once before requesting a withdrawal, so keep this in mind. Other than that, the app does not charge fees for deposit processing. You may want to check with your bank in case it imposes additional charges, as Jack 21 is not responsible for them.
As for withdrawals, you must comply with the minimum allowed limit of $25, or the currency equivalent. The casino will return your winnings to the same method you used for deposits unless that option 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 may be split into several monthly payments. Regarding speed, the casino’s financial department usually processes withdrawal requests within two working days.
Jack 21 Casino App Mobile Games
The last thing mobile users who play at Jack 21 can complain about is a lack of betting opportunities. The mobile version of the casino features more than 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 just a few examples.
Additionally, the app hosts releases from up-and-coming companies like Kalamba, Big Time Gaming, Kiron, Nolimit City, Spinomenal, Virtual Generation, Endorphina, and Gamomat. If you are interested in a certain supplier, tap the provider filter and select its name from the drop-down menu. The majority of the Jack 21 portfolio is available for practice play.
Players can also sort the mobile catalog by categories such as Popular, Table Games, Slots, New, and Favorites. Slots make up the most extensive category, with hundreds of available options.
Mobile users who do not feel like browsing through the enormous selection can 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 who enjoy the classic fruit theme have plenty of options, including Fancy Fruits, Fruit Mania, Zen Fruit, Fruit Burst, and Opal Fruits. There is no designated section for jackpot games, so these titles are mixed with the regular slots. On a more positive note, large jackpots are 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 plentiful, with most titles supplied by Betsoft and Microgaming. Blackjack fans enjoy the widest selection, with variants such as Vegas Downtown Blackjack, Vegas Strip Blackjack, 21 Burn, Pontoon, Pirate 21, and Super 7 Blackjack. Other table games available on the go include No Commission Baccarat, Dragon Tiger, Zoom Roulette, Pai Gow Poker, Oasis Poker, and Sic Bo.
The Table Games section also offers several enticing video poker variants, including Jacks or Better, Joker Poker, Deuces Wild, and Jackpot Poker. The bulk of the live dealer selection is provided by Evolution Gaming, although Vivo Gaming has also contributed. You can face skilled dealers in games like Caribbean Stud, Immersive Roulette, Side Bet City, Blackjack Party, and No Commission Baccarat.
