Kop is a card game for four players, which is popular in the regions of Greater Poland and Kashubia (where it is called Baska).
If you feel like playing kop, but you're not able to meet your friends and play at a table, now you can play for fun against your phone or just practice the game in free time.
Your opponents in the application use a quite complex decision-making algorithm, which gives the feeling of playing live: the AI players don't cheat, don't peek into your cards, and can even bluff from time to time.
The game allows you to choose the variant with two or four stranger cards (via the options screen) and contains a short rulebook.
