A 2-player, 3-dimensional variation on Chinese Chess. Players take turns making Chinese Chess style moves and leaps, but over a set of square grids that are staggered at different levels. The board consists of 6 tiles, each having 16 spaces arranged in a 4x4 square. The tiles are staggered in 3 different heights, and 3d moves are permitted between the tiles. Players make extended Chinese checker jumps with their 16 marbles, trying to maneuver them in to opposing setup region. --- From the Box (bad grammar authentically transcribed): "If you enjoy the strategy of Chinese Checkers, the challenge of Backgammon you're sure to have a blast playing Goppa.
