Jack 21 Info

Jack21 is a Curacao casino that came out in late 2019. Not much mystery around its name: it’s referring to the game of Blackjack even though slots are the main attraction. The basic theme that accompanies the name gives away that the creators didn’t have much inspiration.

So, what are the main characteristics of this gaming hub that we note down for our Jack21 casino review? Jack 21 is a small, international casino with a modern feel website that is bursting with an exciting variety of games.

Another asset of the casino is that you can deposit using both conventional and crypto payments. Except for the lukewarm welcome offer the casino offers daily promotions, a VIP club and exclusive privileges to its players.

The live casino offer isn’t as extensive as the rest of the games, however, you can enjoy almost 50 live games and obviously, among them are several variants of Live Blackjack. The site is mobile friendly and can be easily browsed via a smartphone. Customer support is available 24/7 via email or live chat. All in all, this seems like a good enough casino to play at, but we need to go further in detail before we recommend it.

Jack 21 Casino Online Review

Jack 21 Casino Welcome Bonus

A new player of Jack 21 Casino can claim a superb first deposit package of 120% up to €/$360 plus 50 free spins. You just have to create your account, go to the cashier section, select the welcome bonus and make a qualifying deposit of at least €/$10. Let’s see Jack21 Casino Bonus briefly:

  • Jack21 Universal Bonus: 120% up to €/$360 Bonus + 50 FS

To cash out any winnings coming from the Jack 21 bonus, you should wager it 30x. You will have to use your real balance first and then the bonus funds. The free spins also have playing through requirements set at 50x the winnings. The maximum bet you are allowed to make per spin or hand is €5 or 10% of your total balance.

As long as you have an active bonus campaign,  you aren’t allowed to open a withdrawal request. You will be able to open such withdrawal requests if you choose to leave the bonus campaign. If so, you need to inform the Customer Support and all your winnings generated from the welcome bonus money will be forfeited. The activated bonus will expire within 7 days of its activation.

Jack 21 Bonus Codes

There are no Jack 21 Bonus codes that you can use to receive the signup bonus or any of the rest of the promotions. Both reload bonuses -Monday Magic Bonus and Thursday Spins- come without a promo code. On the other hand, you could use our exclusive bonus code, B50C, to unlock unique bonuses from our partnering casinos. Just keep an eye on our promotions page, and you might find the opportunity to use it.

Which are the Jack 21 Welcome Bonus Hidden Terms?

Jack21 welcome bonus has some very unattractive terms which we have to state:

➨First of all, you will have to wager first your real money and then the bonus funds, meaning that you could quite easily end up with no funds if you fail to meet the requirements.

➨The package of the free spins -50 FS on on the pokies: Fruit Zen, The Golden Owl Of Athena, Mega Gems, Spinfinity Man- are released only after you have met the wagering requirements of the main bonus.

You will be given only seven (7) days to meet the wagering requirements.

Is Jack 21 Casino safe or a scam?

Jack21 Online Casino is owned by Mountberg B.V., a company based and licensed in the jurisdiction of Curacao. Neither the offshore license of Antillephone nor the relatively unknown owner -they operate one more small online casino- give us signs of trustworthiness. The Responsible Gaming page is brief compared to other casinos, but at least it states the RG tools like deposit limits or account closure. There are also weird rules like this one: Each player is obligated to wager at least 20% of their balance through each calendar month for preventing any fraud activities, money laundering and concealment of funds. All of the above, make us a bit skeptical about Jack21, but still we are far from declaring it a scam site.

In Jack 21 you will find a variety of international payment methods that are available to most countries. The casino supports cards (VISA, Mastercard), ewallets (Skrill, Neteller, ecoPayz), prepaid methods (Paysafecard, Flexepin), online banking services (Interac) and even cryptocurrencies -you can buy cryptos via the COINSPAID wallet).

You have to pay attention to the following terms if you use bank transfers for your transactions. The minimum withdrawal amount processed via Wire Transfer is €/$500, while SEPA transfers have a lower limit with €/$100.

The maximum withdrawal amount processed to a player per transaction, in general, is €/$1,000. The casino management declares that the finance department may take up to 2 business days before releasing your funds.

Jack 21 slots and jackpots

With approximately 50 iGaming providers partnering with the site, it’s apparent that you can expect a ton of Jack21 casino games. Slots are all over the place, and you can select among traditional titles such as Immortal Romance, A Night in Paris or Gonzo’s Quest or have a go with the new releases.

We were glad to see many progressive jackpots like Major Millions, Mega Moolah, Divine Fortune and Mega Joker. The presence of the progressive is refreshing as very rarely do they feature in a Curacao casino.

Jack21 Live Dealer’s Review

This is probably the strongest part of this casino. Jack21 Live Casino has a solid offer that includes Blackjack, Roulette, Baccarat and Poker variants. Of course, since the casino is named Jack21, Blackjack tables have the most significant share in this live casino. If you are a high roller, you could try one of the VIP tables.

The industry’s largest names power the casino, meaning Evolution Gaming, Pragmatic Play Live, Vivo Gaming, and Ezugi.
