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 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.
