PROBLEM TO BE SOLVED: To meticulously manage operation data relating to a first special state and a second special state even in the case that a management object is a game machine constituted such that there is a period that the first special state and the second special state advantageous to a player side are generated independently. SOLUTION: A pachinko game machine 1 simultaneously generates both of probability variation and time shortening advantageous to the player side after a big winning ends, ends the probability variation at the time of winning probability variation fall drawing, and ends the time shortening when a pattern variation performance operation at a special pattern display part is executed for the stipulated number of times. A management device 13 judges a probability variation period on the basis of probability variation signals from the pachinko game machine 1, also judges that a time shortening period is ended on the basis of the input number of start signals from the pachinko game machine 1 after the big winning ends, and executes the operation of summing up data relating to the winning rate of pachinko balls of the operation data separately for the time shortening period and a non time shortening period and the operation of summing up data relating to a big winning generation probability of the operation data separately for the probability variation period and a normal probability period.
