Abstract: This invention is directed to a board game comprising a board formed with a plurality of spaced holes disposed in columns and rows, inserts adapted to fit within individual holes in the columns and rows to form a playfield having a first series of spaced, parallel channels and a second series of spaced, parallel channels perpendicular to the first channels extending between the inserts, barrier elements disposed at selected positions about the perimeter of the playfield and consecutively-numbered game pieces movable within the first and second channels. The object of the game is to arrange the game pieces in an array along the first and second channels within the playfield so that the numbers on the game pieces in each column, row and diagonal of the array add to the same number.
