  • Patent number: 4573688
    Abstract: The invention comprises a plurality of playing fields across each of which particular plateaus or levels are mounted, in parallel relationship to one another and having on each thereof a series of stations therealong. The fields are disposed in a three-dimensional environment and the levels or plateaus in each field is traversed by a marker for each player so that upon the marker's return to a finish point in its corresponding field first, its player can be declared the winner of a game or competition played with or on the apparata. Means are provided to climb from one level or plateau to the next. A novel gamepiece or element is utilized to advance each player's marker, in turn, across the plateaus' stations and playing fields. This element itself separates at different times in its use into two members. And it also is itself a basis for self-use in a game played with it in contrast to use with a gameboard.
