How to play:
There are two different ways of playing, either red or black. When you play red you should pick as many tricks as possible, when you play black it's the other way around.

In the beginning you and the computer have to decide what to play. If one of you pick red then the game will be red and the other player begins. If both chooses black the game will be black and the last one to choose will begin.

One Trick:
The player in turn plays one of his/her cards. The player that answeres must follow suit if it's possible. The one who plays the highest card in the right suit wins the trick and is in turn to start the next trick. Ace counts as the highest card.

If the game is red and you pick more than 13 tricks in total you will win the game. If the game is black you will win if you pick lesser than 13 tricks.
