PROBLEM TO BE SOLVED: To provide a game machine capable of changing the setup of a game machine in a game parlor without troublesome labor and providing a new method of using the game machine equipped with a microphone. SOLUTION: The game machine includes: a lottery means for performing lottery so as to determine an internal winning role; a selection means for selecting one direction mode from among a normal direction mode where notification probability of the internal winning role is low and a specific direction mode where the probability is high; a control means for displaying an image for notifying the internal winning role and/or outputting sound; a microphone for converting an input sound into an electric signal; a data-processing means for processing the input sound into data on the basis of the electric signal outputted by the microphone; and a waveform determining means for determining whether or not a specific waveform pattern is included in a waveform of the input sound on the basis of the generated data. The selection means selects the specific direction mode when it is determined that the specific waveform is included in the waveform of the input sound. COPYRIGHT: (C)2009,JPO&INPIT
