  • Patent number: 4953863
    Abstract: A game assembly includes a plurality of toy blocks or cubes containing passsageways which are strategically stacked so as to determine the path of a ball dropped through interconnecting passageways within the arrays of stacked blocks or cubes. The blocks or cubes may be strategically reoriented during play so as to change the path of a ball dropped through the blocks or cubes. The game involves inspecting and/or memorizing moves made by the players taking part in the game, as well as geometric orientation of the blocks or cubes, so as to define a desired path for a ball which is dropped through the stack. A collection plate below is marked with certain designated areas, preferably in color and each player tries to get as many balls as possible through the stack and into his designated area or to predict the exact location for each ball.
