PROBLEM TO BE SOLVED: To solve a problem in which, since there is a single loudspeaker for emitting sound effects or the like in a conventional slot machine, the emitted sound effect is monophonic sound, lacks changes and is easily gotten tired of. SOLUTION: The loudspeaker having a high frequency sound output part is provided on the right and left of a slot machine front surface upper part, the loudspeaker having a low frequency sound output part is provided on the right and left of the front surface lower part of the slot machine, and a sound volume outputted from the left loudspeaker and the sound volume outputted from the right loudspeaker are changed. Thus, the interference point of respective left and right sounds is shifted, and the sound is emitted in such a pattern that reporting sound flows from right to left or from left to right. By emitting the sound in the interference pattern in accordance with the respective winning forms of BB, RB and losing, the winning form is reported. As a result, a player bodily feels various emitted performance sounds with more presence, the excitation degree of the game is increased, and reporting becomes fun differently from the reporting of an internal drawing result just by the lighting of a lamp or the like.
