Castling © 1978 Sega Enterprises, Limited.
The goal of the game is to kill the king by breaking the castle walls via shoveling and shooting arrows. As the wall is taken down, enemy soldiers are sent into the gap. Arrows may be shot at either the king, queen, jack or soldiers; once you've defeated all of the castle soldiers, an additional arrow is added. Killing the king ends the game.
Released during December 1978.
