Abstract: To provide a game machine which can improve the convenience of adjusting a sound volume.SOLUTION: A sub-control CPU can execute a fade-out control by which a sound volume of a background music output in a waiting period is muted over time. Additionally, the sub-control CPU can adjust-control the sound volume in the waiting period. When the adjust-control of the sound volume is not carried out in a second period in which the fade-out control is executed, the sound volume of the background music output in the waiting period attenuates in a specific attenuation mode over time. Meanwhile, when the adjust-control of the sound volume is carried out in the second period, the sound volume of the background music changes in a mode different from the specific attenuation mode. Further, carrying out the adjust-control of the sound volume acts as a trigger, and the sub-control CPU can thus execute a control of outputting an adjust notification sound. An output mode of the adjust notification sound is identical in the case in which the adjust-control of the sound volume is carried out in a first period of the waiting period, and in the case in which the adjust-control of the sound volume is carried out in a second period of the waiting period.SELECTED DRAWING: Figure 6
