From the rules summary in Mü and Lots More:
goal of this unusual game is not so unusual: it is to collect most points. There are 8 rounds and in each of these rounds point cards are distributed. There are 8 tricks in each round. The special features of this game are that each player takes exactly 2 tricks per round and a player can secure a trick by calling “Meinz”. At the end of a round, it is the sum of the numbers in each player’s two tricks that determines the outcome of the round.
