A game system includes, for example, a game console and a plurality of
hand-held game apparatuses functioning as an operating means. In the game
system, a game for causing a plurality of player characters
simultaneously displayed to find a hidden item in a game field is
performed. Then, when a distance between a non-displayed item hidden,
which is an object to be found, and the player character comes within the
range of the predetermined distance, a notification sound that varies
depending on the distance, for example, is output from a speaker of the
hand-held game apparatus that operates the player character.
