<P>PROBLEM TO BE SOLVED: To detect a fraudulence by nail adjustment for raising winning rate in a game machine configured to change the winning rate depending on the arrangement and attitude of nails raised in a game area, whereas such nail adjustment is sometimes performed by a manager of a game parlor or the like in order to enhance gambling property. <P>SOLUTION: In the Pachinko game machine 50, a warning operation is performed by transmitting an abnormality warning command to a sub-integrated controller (S950) when the winning frequency to a first start pocket for 10 minutes reaches 100 to 150. When this state continues for three times (S945: no), the game machine is brought into a game impossible state. Thus, not only an illegal action using radio wave or a magnet that generates great deal of damages by rapid increase in the winning frequency but also the fraudulence by nail adjustment for continuously increasing the winning frequency, though not so much as such the illegal action, can be detected. <P>COPYRIGHT: (C)2013,JPO&INPIT |
