As far as I know if you play for example in real life with a dealer then you have a chance to Hit one more, even with blackjack. Should this be different when it is digital?

This is such an easy way to double your money. With
provably fair you have very good chances to win also.

I was playing the game, my phone ring and I came back after 5 minutes.

Now I can't remember what was my last move.

Can someone tell me, is that stand button for blackjack or K 6   I don't want to lose money because they didn't test software before releasing the game.
