Auf falscher Fährte

From BoardGameGeek:

The title means "On the wrong track" and, in this trick-taking game, that's just where you can find yourself. Players compete to take either the most or the fewest tricks, depending on the total value of a few hidden cards played at the beginning of each hand. Problem is, however, players aren't sure whether most or least is good until after all 4 cards are revealed...
