The game box is the castle. That is where the game is played. The players' mice start from the four battlements at the corners. First, the players lift the roofs, discover treats there and try to guide two of their own rodents onto cheese symbols of the same kind. To make it easier for themselves and more difficult for the other players, each player can also move the floor along with the holes, which causes many a mouse to tumble into the castle cellar. The player who completes his cheese collection becomes the future rodent lord of the castle and wins the game. The successful game designers Jens-Peter Schliemann and Bernhard Weber came up with this funny castle spectacle. Illustrator Victor Boden has set the scene for the cheese castle in a particularly atmospheric way with beautiful and funny pictures.
