This app wants to be the demo of the trump suit game, a trump suit game simulator with two players without multiplayer written in maui.
It does not pair cards, but it uses the rule of taking the largest amount of cards.
It must be gamed in attack, so you have to take even 10, 9 and 8, because of the IA makes it.
The 1 worth 11, the 3 worth 10, the 10 worth 4, the 9 worth 3 and the 8 worth 2. 4*4+4*3+4*2=36, so only three 3 must be taken to win, if you plays to take 1 and 3, you have to take all of them to win.
There are few personalization respect to official game, and it does not have a timer beetwen the plays, but it has a button.
