Abstract

Abstract The present invention relates to a stop-control device of a rotary gaming machine used for controlling the stop action of a rotor such as a reel in a rotary gaming machine such as a slot machine. In the rotary gaming machine, a table for allocating the symbol combination mode of the rotors against the combination of codes is stored in memory means. When starting the game, after generating a plurality of any codes from code generating means, stop-control means specifies the symbol combination mode corresponding to the combination of codes generated by the code generating means referring to the memory means, and allocates the symbols to respective rotors which are stopped at a predetermined position. According to such a configuration, in order to change the probability of appearance of the symbol combination mode, it is just necessary to change the content of the table stored in the memory means, or an allocation of the symbol combination mode of the rotors against the combination of codes, thus the probability of appearance can be changed with a very simple operation.
