counting number of times of executing the base game; (c) causing the display device to display a
countdown effect image stored in a memory, while the counted number of times of executing the base game reaches a second predetermined value after reaching a first predetermined value; and (d) transferring the base game to a free game executed without betting a gaming medium, in a case where the number of times of executing the base game reaches the second predetermined value; and a
communication interface for notifying to the common display the controller-counted number of times of executing the base game, the common display device, comprising: a
communication interface for receiving notification from each of the gaming machines; a memory for storing a
countdown effect image for each of the gaming machines; and a controller, which performs processes of: (a′) judging whether or not there exist a plurality of gaming machines at which number of times of executing the base game reaches the first predetermined value, based upon the number of times of executing the base game, which is notified from each of the gaming
machine; and (b′) preferentially displaying a
countdown effect image for a gaming
machine with a smaller number of times of executing the base game, which is to be executed until a transfer to the free game.
