<p>PROBLEM TO BE SOLVED: To suppress deterioration of operability by forcing a player to perform the same operation again and again while preventing a complication of a staff member's work caused by the mischief of unnecessarily changing sound volume.SOLUTION: A game machine includes: sound output means for outputting a sound according to a progressing status of a game; initial sound volume setting means for setting initial sound volume of the output sound output from the sound output means; an operation part for accepting a sound volume changing operation for changing the sound volume of the output sound; set sound volume changing means for changing the set sound volume of the output sound according to the sound volume changing operation; and sound volume resetting means for resetting the set sound volume to the initial sound volume when a predetermined time is reached, in which the standby time in which the game is not played is different between in the case where the set sound volume is changed to a level smaller than the initial sound volume and in the case where the set sound volume is changed to a level larger than the initial sound volume. In the case where the set sound volume is at a level the same as the initial sound volume, the set sound volume that has been ultimately set is maintained irrespective of the standby time.</p> |
