Abstract

A game machine displays in a display window a first and a second series of symbols in a column such that the first series of symbols are movingly displayed and thereafter a predetermined number of stationary symbols of the first series are displayed in a display window when the first series stops. If at that time a specific symbol of the first series, e.g. an opening or a transparent area, stops in the display window, the second series of symbols displayed in the position of the specific symbol are moved, and then a symbol of the second series is stopped in that position, whereby an additional game can be played in connection with the second symbol series.
