Abstract
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. The direction and range finder includes a protractor type direction finder portion and a straight edge type range finder portion. The cannons may be pivoted about both horizontal and vertical axes so as to vary the direction angle of elevation at which the projectile is ejected from the cannon. The appropriate elevation angle is determined by means of an elevation finder chart which indicates the proper elevation for a given range.
