Abstract
Abstract A game in which a player attempts to move an object through a maze has a housing which has an upstanding fulcrum located within the housing. A platform member having a maze located on its upper surface which is viewable outside of the housing is located in the housing above the fulcrum such that the platform member rests on the fulcrum and is tiltable a full 360 degrees about the fulcrum. A portion of the platform serves as a cam follower. A cam member is rotatably mounted on the housing adjacent to the fulcrum and positioned so as to be capable of interacting with that portion of the platform serving as a cam follower. In response to rotation of the cam the platform, including the maze located thereon, is tilted. An object located within the maze is capable of moving within the maze in response to tilting of platform.
