Claim 1

A war board game comprising: (a) a gameboard having a playing surface overlaid with a grid pattern, said grid pattern divided into four symmetrical segments including water squares, land squares, mountain squares, island squares, starting squares, headquater squares and airstrip squares, so that four players can play said game; (b) four sets of game pieces, each set for one of said players having indicia on one side defining two naval ships, one tank, four number one spies, four number two spies, four number three spies, and a president, each said game piece adapted for specified movement restricted to prescribed squares on said gameboard; (c) a random number generator for indicating amount of movement for said game pieces on said gameboard, wherein each of said water squares, land squares, mountain squares, island squares, starting squares, headquater squares and airstrip squares are uniquely identified by having their own identifiable indicia thereon, wherein each of said sets of game pieces are uniquely identified by having their own identifiable indicia thereon, wherein said gameboard further comprises: (d) a plurality of intersecting straight tracks; and (e) a plurality of removable squares each having a different identifiable indicia on an opposite side thereof, said squares being able to fit abuttingly within said intersecting tracks to form said grid pattern from either of said opposite side so that said squares can be interchangable to vary the type movement over said grid pattern and thereby modifying the complexity of the game.
