ABSTRACT:
A gaming machine has a variable display device for variably displaying symbols for each of a plurality of symbol columns by moving each of the plurality of symbol columns separately in a predetermined direction. The plurality of symbol columns are each formed by a plurality of symbols arranged in the predetermined direction. A drive signal for operating the variable display device is generated when predetermined gaming conditions are satisfied. In response to the drive signal, there is determined a combination of stop symbols to be displayed when the symbol columns are stopped. Positions of the stop symbols are detected separately for the symbol columns, respectively, and position signals indicative of the positions of the stop symbols are generated, respectively. Correction amounts for correcting the positions of the stop symbols are determined based on the position signals. In response to the drive signal, control of the movement and stop of the symbol columns displayed by the display means is carried out, such that the movement of the symbol columns is controlled at the start of movement thereof by the use of the correction amounts until the speed of movement of each of the symbols columns reaches a predetermined uniform speed.
