Aber Hallo!

From the rules translation (downloadable here): A tricky card game for 3 to 4 players from 10 years. All of us know how to play trick-taking games. And, usually, they have a trump color. But, if trump can change in every trick, watch out. Don't lose sight of the big picture... The players try to get as many points as possible through skillful card play. However, the cards are worth points only if you also manage to grab chips of the corresponding color, too.
