Split-Level Aggravation (1971)

Split-Level Aggravation is a 3-dimensional game whose design changes continually throughout its play. The object of the game is for a player to move all 4 of his playing pieces around the game board from his base position to home. In order to reach home (if no shortcuts or changing of level are used), a playing piece must travel around the outer edge of the playing surface on which its base is located.
