Patent US 4,902,017

A war simulation board game utilizes a playing board having a grid pattern of square segments, each square having a centrally located circular target zone. Game pieces simulating war vehicles move on the grid pattern according to a spinner. Opposing players "fire" on each other's game pieces and headquarter zones by placing the tip of an ink marker on a target zone of a square occupied by one of their game pieces and orienting the marker in a vertical position, supported by an index finger contacting a butt end portion of the marker. The player then applies an external force to the marker forcing the marker tip to freely slide away from the target zone and forcing the marker to leave contact with the player's index finger as it falls in an arcuate motion. The sliding marker tip forms an ink line segment simulating a projectile shot path on the board surface. If the resulting ink line segment passes through a target zone of a square occupied by an opposing game piece, the "shot" is scored as a hit. At opposite ends of the game board are chance result cards which are placed face down. One of the chance result cards at each end of the board simulates a military headquarters, while the remaining cards simulate hidden bombs. Players attempt to find and destroy the opponent's headquarters.
