To provide a game machine for providing a sport game to be played between an operation target team and an opponent team, which allows a game player to relatively readily find out the position of a teammate player object. A position announcing sound data storage unit (72) stores position announcing sound data in association with a relative position condition concerning the relative position of the teammate player object relative to the position and reference direction of the operation target player object. A relative position determination unit (76) determines whether or not the relative position of the teammate player object selected by the position announcement target selection unit (74), relative to the position and reference direction of the operation target player object, satisfies the relative position condition associated with the position announcing sound data. A position announcing sound output control unit (78) controls a sound output unit (80) so as to output a sound based on the position announcing sound data associated with the relative position condition determined by the relative position determination unit (76) as satisfying the relative position condition.
