Abstract: A war game for two opponents each having an assembly including a playboard hidden from the opponent by a shield board, both boards having a grid of target-receiving sockets identified by co-ordinates, the playboard representing an expanse of water and additional sockets therein locating relatively large platforms representing land masses so that playing piece targets, arbitrarily placed on said platforms, themselves arbitrarily placed, are still co-ordinately identified enabling shots, misses and hits on land, sea and targets to be called, and a rack for hit targets, visible to the opponent, is provided on each shield board. The playing piece targets, aside from ships and mines, include units associated with land masses such as fuel and water depots and negative-counting targets such as churches and hospitals.
