Abstract: Apparatus and methods are provided for a game including a playing board having means for pivotally mounting a plurality of projectile shooting cannons. The playing board includes first and second orthogonal grid indicia arrays so that the location of a movable target may be designated by indicating specific first and second grid indicia, of the first and second orthogonal arrays, respectively. Also included is a plotting chart which comprises a scale reproduction of the playing board, including grid indicia arrays which are scaled duplicates of the grid indicia arrays of the playing board. A direction and range finder is provided for use with the plotting chart so that the direction and range of the movable target on the playing board may be determined by marking the location of the target on the plotting chart with a plotting pin and then rotating the direction range finder until it engages the plotting pin.
