  • Patent number: 4674749
    Abstract: A maze puzzle, characterized by a quality of flexibility, pliancy or suppleness, includes a maze or labyrinth consisting of a network of passages having flexible walls that are manipulable by the player to effect movement therethrough of a solving piece such as a ball. The walls of the maze puzzle preferably are of flexible, double layered fabric with the outer or cover layer serving to conceal the inner or liner layer which may be closed upon itself to form hidden obstructions at selected locations in the maze which prevent passage of the solving piece. In this manner, concealed dead-end passages are provided whereby the player must rely on his sense of feel to solve the puzzle. The cover layer preferably is of a soft and supple cloth fabric that is pleasing in appearance and feel.
