Whoever wrote this program should first learn how to play jass.
There are too many bad plays to start mentioning them.
I played about 50 games and finally decided to write this review. I gave it a chance.
There are not enough settings to customize the game, e.g. weisen the 6, 7, 8 when playing undenufe.
A total waste of $ 3.99.
