Abstract: A three dimensional, multiplanar board game device is provided for which the game object is to place a plurality of game markers on the device in a straight line or row in any of the three available dimensions (X-Y-Z axes). A plurality of transparent boards each have a configured aperture therethrough and a square grid of marker seats. The number of the seats per each board equals the number of boards to the power of two. A support shaft or rod configured in cross section, as to pass through the configured aperture of each board, nonrotatably aligns the boards and the grids in a vertical arrangement with respect to each other. Hollow cylindrical spacers are provided to support the boards on the shaft in spaced relation adequate to permit hand insertion between the boards. A top handle is adapted to carry the device in a secured and assembled condition ready for play.
