The little box that will make you lose your marbles! It is a 3D labyrinth which is played blind. It’s a new game presented in the form of a cube. The cube holds a marble that is alternatively visible on the top or bottom face, depending on what stage of the game you are at. On each of these two faces, the player finds a map indicating the course that needs to be taken in order to direct the marble towards its destination. The map is composed of 7 plots representing the successive layers that must be crossed.
