Three-dimensional strategy game

A three dimensional, two-player strategy game has vertically aligned base, and transparent second and, preferably, third game boards, each game board having a grid pattern defining game board spaces which are vertically congruent, each player having a set of game pieces, and posts maintaining the boards in vertical alignment with said grid patterns vertically congruent. There are a plurality of posts with each post having a stepped shoulder defining a board level for the second game board. The second game board has a plurality of apertures located at grid intersections which are inward of the perimetrical edges of the second game board, the base and third game boards have cavities at corresponding grid intersection positions for snugly receiving the upper and lower ends of the posts, respectively. The grid patterns are M units long and N units wide to define MxN game board spaces, with the game board spaces being sized to receive each game piece individually during the course of a game without impairing visibility of all game pieces on the boards at any given time, and the sets of game pieces are comprised of W major, X number of middle-level and Y number of game pieces, with game pieces being arrayed in predetermined game board spaces starting positions for each player. Each major game piece is movable one game board space at a time in any direction and only in one plane, the middle-level game pieces are moveable one game board space in any direction on the same plane and directly to a game board space directly congruent above or below the game board space it is occupying. The low-level game pieces are moveable one game board space in any non-congruent direction on a different plane, one plane at a time.
