<P>PROBLEM TO BE SOLVED: To bring a state in which a preferential symbol can stably vary when a lottery result is derived and displayed using a plurality of symbols. <P>SOLUTION: A main control device (main control CPU) of a Pachinko machine controls a first special symbol display device or a second special symbol display device to control the variation display and stop display of the first special symbol or second special symbol. When the prize winning corresponding to the first special symbol or second special symbol is generated, the main control device stores respective jackpot determination random numbers. When both storages are present, the main control device determines a jackpot using preferentially the storage of the second special symbol. When the prize winning corresponding to the second special symbol is generated while both storages are absent, and when the number of storages of the second special symbol becomes zero with the start of variation, the main control device sets the long variation time of the symbols even in high probability/short time, and thereby facilitating generation of the next prize winning. <P>COPYRIGHT: (C)2013,JPO&INPIT |
