Traditional German card game played with a standard 32 card deck, roughly 200 years old.
A solo player (determined by a bidding process) plays against a coalition of the other two players. The solo player can choose between determining suit of trump, Grand (no trump) and Null (no tricks wins the game).
Complex scoring (and bidding) dependent on type of game announced, number of trumps, margin of winning, (optional) open play of cards.
