In Biberbau & Co., players have to construct a house with two floors (for the frog), three floors (rabbit), four floors (beaver), and one with one to five floors for the hamster. They take turns drawing cards — which represent levels of a building — deciding after each draw whether to finish the house with the current number of levels for the specific kind of animal or continue drawing to go for a higher house worth more points in the end. If they draw two identical levels, however, the building is forfeited and their turn is over.
