I am not so good on blackjack, but this game is really simple, the highest card wins, its around 48/52 for the casino, because when there is war you stake another unit, but you win only one if you win, but anyway wars happen rarely.
There isnt cashier like in rtg casinos, its a lot more different. I have betting history, but I am lazy to count all my bets
All I want to know if the WAR is available for clear the bonus, I will wait someone that played there to confirm it.
