To provide a game machine capable of suppressing a fraudulent act performed by using a "hanging board".

When a special loss is determined (S306: Yes) as the result of a normal lottery performed by the MPU 201 of a main controller 110 (S301, S306), a special loss stop kind command "F111h" is read out of a ROM 202, and low-order bytes of the command are rotated leftward by the portion of the number of bits being the same as the value of a first processing condition memory 203f and processed (S309). Thus, one of four kinds of processed special loss stop kind commands is selected. Then, the processed special loss stop kind command is transmitted to a sound lamp controller 113 (S310, S901). The sound lamp controller 113 that has received the processed special loss stop kind command allows the low-order bytes of the processed special loss stop kind command to be rotated rightward by the portion of the number of bits being the same as the value of a first decoding condition memory 223g and restored (S1307).
