Hill is a chess-like battle game for 2 or 3 players who control armies made of Airplanes, Cannons, and Tanks. The first player to plant his Flag (King) in the center circle wins. Enemy pieces can be captured by entering their space. Planes are like chess Queens and Cannons are like Rooks. Tanks can move only two spaces. There is also a Trench which is a defense piece that blocks movement.
