This is my review of Jack21 Casino.

Every online casino user is different. Being that I have loads of experience talking to people about casino games, I have noticed that there are many archetypes of players. For instance, some people only like to play slots and stick to their one or two favourites every time, whereas others are constantly trying to change things up and play a host of games and game types. During my casino visits, I sometimes find myself doing slots, sports betting and blackjack in one session. I mean, why only experience one type of fun when you can use your entertainment budget to give everything a try at once?

Jack21 Casino has clearly taken its name from the game of blackjack where 21 is your ideal hand (consisting of an ace and a ten, though, not just any type of 21). Still, I do not know why the casino would include jacks in their name as they are not the only way to get 21… Anyway, it was Mountberg BV who came up with this casino in 2020. Perhaps I should send them a formal letter to ask them about the story of Jack21…

Looks and feel of Jack21 Casino

Jack21 has the looks of a professional online casino brand, but I am not so sure that the colour scheme it has chosen pleases my eyes. Instead of striking and clear-cut colours, Jack21 Casino favours blueish-green—a colour rarely seen anywhere else! Perhaps Mountberg wanted for the casino background to look like a giant table game or something…

At least the Jack21 interface is friendly to users. The webpage is not too full of stuff, and you can even search for games based on the provider, which is something that a slot nut like me will always know to appreciate!

Bonuses and rewards

Jack21 does not only cater to the most typical casino players. On its promotions page, it lets you filter promotions for casino games, live casino games, and even poker. At the time of writing, however, there were no live casino or poker campaigns available. Hmm…

The welcome offer at Jack21 saw new customers receiving a 120% bonus up to 360. The casino itself dubbed this the perfect start to your casino journey, and who am I to say that they are wrong? Truthfully, though, I am a casino critic and I will say that the x30 wagering for both the deposit and the bonus could have been a bit lower.

Games Selection

Some online casinos only have games from one single game provider, whereas others try to get as many as they can under the same roof. Amazingly, Jack21 Casino actually has around 50 game providers, which is not a feat that you should take lightly! I could go on and on listing all the different game studios available but instead, I will name you some of the best ones I saw in NetEnt, ELK Studios, Big Time Gaming, Thunderkick, Play’n GO and Push Gaming.

For those wanting to go for those elusive 21’s, why not give Jack21 Casino’s live section a chance? A wide variety of blackjacks, roulettes, and other table game favourites await from the likes of Evolution Gaming, Hollywood TV, NetEnt Live, Ezugi, Vivo Gaming, Asia Gaming and more! It truly is staggering what Jack21 has been able to pull off!

Safety and security

Jack21 Casino’s biggest problem would have to be its unavailability of a proper European license. The Curacao license found here has been deemed weak by countless igaming professionals, and I am not one to go against the grain with this one. I, too, have found myself abused by my fair share of Curacao-licensed casinos. Some of the are good, though, so feel free to take my judgements here with a grain of salt if you please.

Banking options at Jack21 Casino

Jack21 usually takes 2 to 3 days to process its players’ withdrawals. Deposits, on the other hand, can be performed via services such as Visa, Mastercard, Skrill, Neteller and Paysafecard.


Jack21 provides its customers with sustained live chat service. You can send in your queries 24/7/365 and expect prompt answers to them as well.

My experience at Jack21 Casino

Jack21 Casino would have probably made an almost lasting impression on me if it were not for the lack of a European licence. While it is better than your average Curacao casino, it is no slam dunk compared to its safer alternatives that also often come with even better casino bonuses.

This site is dodgy. Selected the 300 free spins before I deposited the required $20. Didn’t receive the 300 free spins. Went on chat and was informed that because I had started playing the credit I have, he could not add the free spins on. If I could chat with them when I have deposited again before I start playing they will add the free spins then. What a load of shit. They’ll just come up with another reason.
