The two cards with the number 21 in the casino’s logo may mislead you into thinking it’s a Blackjack venue. However, there’s much more to Jack21 Casino than Blackjack. In fact, this card game isn’t even the focal point.

Jack21 Casino is as new as it can be. It was launched in 2020, so it has yet to become popular among gambling enthusiasts (or blacklisted, depending on its business practices).

The casino is owned and operated by Mountberg BV. The company is registered in Curacao, so the casino holds a license issued by that jurisdiction.


The website is rather simple, yet well-designed. It’s easily navigable so that you can find every piece of information you may need without wandering through it.

As soon as you load the website, you’ll see a slider advertising the casino’s comprehensive promotion selection. Above it, there are shortcuts to the game library, bonus section, and support page. The login and register buttons are in the upper right corner, along with the list of language options.

Below the slider, there’s a brief game selection preview. As you continue scrolling, you’ll see some promotional material of the game library and promotion selection, as well as the list of recent winners.

At the bottom of the page, there are logos of available payment options and software providers. There’s also a list of links redirecting you to different sections of the website, such as FAQ, Privacy Policy, and others.

Jack21 Casino Bonuses and Promotions

The casino holds as many as seven promotional offers. They’re organized into three categories — casino, live casino, and poker. Additionally, there’s a VIP lounge (Club 21).

There are four other bonuses and two tournaments. The “Exclusive Monthly Gifts” promotion comprises bonuses and cash rewards. The “Monday Magic Bonus” is a 40% reload bonus up to €200 with 30x wagering requirements. Moreover, there are two daily promotions. There’s a live casino night every Wednesday when the players can get a 10% cashback bonus. Another daily promotion is the Thursday Bonus of 50 free spins for all deposits exceeding €20. As for the tournaments, there’s the “Battle of Gods” with a €5,000 prize pool and “Drops & Wins” with a €2,000,000 prize pool. 

Welcome Offer

The welcome package comprises a 120% match bonus up to $220 and 20 free spins for one of the following games: Northern Sky by Quickspin, Sahara Nights by Yggdrasil, and The Golden Owl of Athena by Betsoft. The smallest deposit you have to make to claim the welcome offer is $10. While the match bonus has a wagering requirement of 30x, you have to play through your free spins winnings 50 times before you can request a withdrawal. Slots and scratch cards contribute 100% to the wagering requirements, virtual games make a contribution of 20%, and all the other games contribute 5%.

Sign-Up Guide

Jack21 Casino features the free play option, so you can play most of its games without depositing or even having an account. However, when you decide to include money into the game, you’ll have to register.

The registration form opens up on the click of the “register” button. It has one page. You’ll have to enter your first and last name and your date of birth. Then, you’ll need to share your residential information (choose your country from the list and enter your city, address, and zip code). You’ll also have to create a username that has at least four characters, provide your email address, create a password, choose a currency, and share your phone number.

Before you can create your account, you need to confirm that you agree with the casino’s terms and conditions and privacy policy. Optionally, you can choose to receive promotional emails. Lastly, you can enter your referral code and click on the “create account” button at the bottom.

Desktop Computers vs. Mobile Devices

Contemporary gambling enthusiasts have new requirements. Computer gambling isn’t enough anymore, so modern gambling websites mostly feature the mobile-friendliness option.

Since it’s recently gone online, it’s not surprising that Jack21 Casino is one of such websites. It’s available across the platforms. You can access it on your computer as well as your mobile device, whether it may be iOS or Android.

There’s no app, so you won’t have to clear your storage space for it. You can load the website on your smartphone or tablet through a compatible mobile browser.

There are no differences between the computer and the mobile version of the website. Both are equally easily navigable. As for the games, most of them are available on mobile devices.

Casino Games

The online gambling market offers variety and diversity. They don’t refer only to casinos, whose number grows each month. They also regard virtual casino games. Software providers design and release new titles monthly. New casinos strive to start off by including as many of them in their game libraries, while older ones regularly enrich theirs.

Jack21 Casino holds more than 1,000 games. There are slots, lottery games, table games, and (supposedly) live casino games. Moreover, there are categories featuring the most popular games and new arrivals.

As for the developers supplying the casino, the selection includes some of the best providers in the industry, such as Microgaming and NetEnt.

Live Casino Options

Even though the website states that there are live games, we’ve failed to load the relevant category. The live casino section seems to be empty (there’s a notification stating that there are no games for that search). However, the casino has a promotional offer for live casino games, so this may be a temporary glitch.

Financial Information

Engaging in real-money gambling at a certain casino requires you to know which payment options are available. Moreover, you should also get familiar with other financial information, such as the minimum deposit, minimum withdrawal, maximum withdrawal limit, withdrawal time, and whether there are additional charges for transactions. 

When it comes to Jack21 Casino, the following payment methods are acceptable for depositing: Skrill, Mastercard, Neteller, Visa, Cashlib, Paysafecard, Siru Mobile, AstoPay card, bank transfer, Neosurf, ecoPayz, Zimpler, Pay4Fun, Interac, Advcash, Exmo, Qiwi, Mir, Bitcoin, Ripple, Ethereum, Yandex Money, MTC, MegaFon, Beeline, and Tele2. The processing time for all deposits is instant, except for those via bank transfer, which depends on the bank. The minimum deposit varies depending on the method.

As for withdrawing, the following payment options are available: Skrill, Mastercard, Neteller, Visa, Paysafecard, AstoPay card, bank transfer, ecoPayz, Zimpler, Pay4Fun, Interac, Advcash, Exmo, Qiwi, Mir, Bitcoin, Ripple, Ethereum, Yandex Money, MTC, MegaFon, Beeline, and Tele2. The processing time is generally instant, although it takes 1-5 days for withdrawals via Mastercard and Visa to be processed. The minimum withdrawal is €20, while the maximum withdrawal limit is €10,000. All winnings exceeding that sum are delivered in weekly installments.

Lastly, the casino accepts the following currencies: EUR, USD, GBP, BRL, RUB, MXN, CAD, UAH, and AUD.


You shouldn’t take registering at an online casino lightly. If you choose an unsafe website, you can become a victim of a security breach. Since you share your personal and financial information with a casino when you create an account, you need to be sure that casino is secure. Otherwise, you’ll be prone to malversations such as identity theft and bank fraud.

Jack21 Casino uses encryption methods to protect the players’ sensitive data. When it’s encrypted, it can travel safely through the internet because there’s no risk a third party may have access to it.

As for fairness, the casino uses a random number generator. An RNG ensures that the outcomes of games of chance are completely random and thus impossible to manipulate.

Customer Support

Unlike most modern online casinos, Jack21 Casino doesn’t offer the live chat option. Therefore, if you experience an issue and you need assistance, you’ll have to contact the customer support team via email at support@hd.jack21.com.

In case you don’t need help dealing with a problem, but the answer to a question, you can consult the FAQ section. You can access it either by clicking on the “support” button at the top or by following the link at the bottom of the page. There are five categories of questions and answers — account, deposit, withdrawals, bonuses, and games.

Finally, the website is available in eight languages (English, German, French, Russian, Spanish, Portuguese, Ukrainian, and Azerbaijani).

Casino Markets

Online casinos are much more accessible than land-based venues. You don’t have to plan a trip to reach one — you can simply load a website on your computer and engage in real-money gambling.

Nevertheless, a good internet connection isn’t the only requirement. You can’t access every casino online. Depending on your residence country, some of them are off-limits.

Jack21 Casino doesn’t welcome players from the countries unavailable on the registration page.

Additionally, there are restrictions to some games as well. Guns & Roses, Jimi Hendrix, and Motörhead aren’t available in the following territories: Australia, Azerbaijan, China, India, Malaysia, Qatar, Russia, Thailand, Tunisia, Turkey, and Ukraine. Universal Monsters (Frankenstein, the Bride of Frankenstein, Dracula, The Mummy, The Wolf Man, Creature from the Black Lagoon, and The Invisible Man) and Scarface are unavailable outside of the following countries: Andorra, Armenia, Azerbaijan, Belarus, Bosnia and Herzegovina, Brazil, Georgia, Iceland, Liechtenstein, Moldova, Monaco, Montenegro, Norway, Russia, San Marino, Serbia, Switzerland, Ukraine, Croatia, Macedonia, Turkey, Austria, Bulgaria, Cyprus, Czech Republic, Finland, Germany, Greece, Hungary, Ireland, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Peru, Poland, Slovakia, Slovenia, and Sweden.


Jack21 Casino seems like a trustworthy gambling website. It’s safe, secure, and fair, and it offers a broad array of games. However, it needs work, especially because of the absence of the live chat option. Since it’s only recently gone online, it’s possible that it’s still “under construction.”
