Abstract: The invented game includes a playing field with a pattern of defined areas adjacent to one another, sets of playing pieces for each player, and a single marking piece which is several times the height of a playing piece. The playing pieces are configured such that they are stackable on top of one another and such that a stack can be inverted. The game is played by a first player placing the marking piece on any defined area. The next player then places one of his playing pieces on any other defined area. The next player places one of his playing pieces on any unoccupied area or stacks his playing piece on the playing piece already on the playing field. Each player then, in turn, either places a playing piece on an unoccupied area, stacks a playing piece on top of another playing piece or on top of an existing stack of playing pieces, or inverts an existing stack of playing pieces.
