Abstract: A method of playing a modified chess game wherein the general rules of play are the same as standard chess with the addition of a new rule providing a board which can shift horizontally and/or vertically, adding new possibilities and strategies to the orthodox game of chess.

Abstract: This is a novel two-player board game which uses addition and subtraction to initiate the movement of a player's pieces. The game is comprised of two sections; each section consists of a plurality of spaces containing integers. The interior section is comprised of opposite sides separated by zeros, one side containing negative integers and the other positive. Pieces are provided to each player for separate use in the exterior and interior sections. Movement is initiated by positioning pieces in the exterior section on spaces whose integers produce a difference of two integers found in the interior section, thus enabling pieces to move from one space to another. The object of this game is to be the first player with all his/her pieces positioned within the interior section on spaces whose integers when added together equal zero.
