<P>PROBLEM TO BE SOLVED: To prevent changes in allowance levels for setting probability with which allowance of the derivation of results of prize-winning display is determined in each game from being immediately perceived by players. <P>SOLUTION: A winning rate of each prize-winning combination in an internal lottery is determined in accordance with differences in a set value. In a RAM, a set value work for storing a set value is provided separately from a work for storing data for indicating a progress status (credit, game situation, or the like) of a game other than the set value. When the power is turned on while a setting key switch provided inside the slot machine is turned on, setting changing processing is performed, making it possible to rewrite the set value stored in the set value work in the RAM. Data stored in a work other than the set value work in the RAM is not cleared only by power-on while the setting key switch is turned on, and is cleared on condition that the power is turned on while a data clear switch is turned on in addition to the setting key switch. <P>COPYRIGHT: (C)2012,JPO&INPIT |
