Mau Mau - card game (iPad)

Mau Mau is one of the most well known card games and the predecessor of the famous game Uno. Also know under the names Auflegen, Tschau Sepp, Neunerln, Pumba, Makao, Prší and Ocho Loco(s). It's similar to games like Crazy Eights, Switch and Uno.

The rules are pretty simple and easy to learn but yet this game has some surprising elements and is fun to play. Goal is to play your own cards before your opponents do. You play either the same color or the same number.
Play a 7 and the next player has to take 2 cards or has to play a 7 by himself, so the next player would have to take 4 cards.
Play a knave and you can choose a new color, but be aware that you can't play a knave to counter another one.
Play an ace and the next player has to miss that turn.

A multiplayer mode is already in the making!
