A 2-player abstract game played on a chess-style board, where opposing pieces (of three distinct kinds: cubes, pyras and tetras) seek to win by capturing the fourth and leader piece of each army: the sphere. Each piece moves exactly as many squares as it has corners: tetras move three squares, pyras five and cubes eight. No pieces can be jumped, but pieces are captured when an opposing piece ends its' move on the same square. When a sphere is captured, the game is over.
