Game description from the publisher:
Each morning while being milked Lieselotte impatiently peeks out at the farmyard. Lieselotte has a favorite pastime each and every morning: She loves to startle the mailman! The farmwoman, however, disapproves of this behavior and Lieselotte has to be careful not to be caught in the act. Who can help Lieselotte frighten the mailman and not be caught by the farmwoman.
In Lieselotte lauert, the faces of the four dice indicate the right moment for Lieselotte to frighten the mailman with a loud "Boo!" without getting caught by the farmwoman. When certain combinations of symbols appear on the dice, Lieselotte can moo as loud as she likes. The player who first spots a matching combination among the jumble of colored dice hits the cow buzzer and receives a mailman tile, worth one point. Collect the most points, and you win!
