It is obvious, if new players are increasing, the marketing plan and advertisement of the casino is effective. And they have these features that these new players is looking for. I have read the recent post about rewards. Blakcjack.fun is to generous by giving bonuses if players are active in chat, participate in voting, and more. It is like a domino effect bonus where it starts on a fund deposit bonus.
Yes indeed recently they added some interesting features like fixed rakeback 20% or 1 hour rakeback 70% next maybe cashback
latest update bonus rain added to bonus balance and take 70x wager so really nothing free

we have to compete with whales for prizes.
I just recently saw the blackjack.fun having a 20% Rakeback for the games but imagine with the 70% this could gain another marketing level of advertisement it's all in favour of the players seems they enjoy a lot of bonuses and perks once they play.
