  • Patent number: 6260848
    Abstract: A modified game of chess compirsing four individual armies is disclosed herein. There can be two, three or four participants. A gameboard is modified to comprise seventy-two alternating smaller squares of equal dimensions for a total of 144 squares, but of two distinct alternating colors. The gameboard has a border with linear groups of designation marks for initial pawn movements. The methodology is novel in that two, three, or four participants, each initially with his or her own modified army of chess pieces, can form or dissolve alliances with other armies. Armies may also, by checkmate, control one or more defeated armies. The result is a modified game for experienced players.
