Patent ID: 8388431

Claim:
A gaming machine, comprising: a plurality of gaming terminals each having a display which arranges thereon a plurality of symbols, a symbol column image storage which stores a plurality of symbol column images, having the plurality of symbols, and a terminal controller; a central controller connected and in communication with the gaming terminals; a terminal information memory which stores information output from each of the gaming terminals to the center controller, the information including identification information for identifying each of the gaming terminals; and, a common game symbol value storage which stores a common game symbol value table in which a plurality of common game symbols, that correspond to symbol column images only played in the common game, are associated with points that are weighed in advance, respectively, wherein the terminal controller is programmed to perform the following steps of (a1) to (a4): (a1) repetitively running, independently of the other gaming terminals, a unit game which scrolls the symbol column image, stops the scrolling to rearrange a plurality of symbols, and determines a payout of each unit game in accordance with an arrangement of the rearranged symbols; (a2) repetitively running, in sync with the other gaming terminals, a common game which performs a common scrolling process wherein the symbols in the unit game are replaced with the common game symbols and the common game symbols are rearranged after the scrolling of the symbol column images is stopped, in response to a common game start command from the center controller; (a3) determining which common game symbol is obtained among the common game symbols rearranged in (a2), and calculating, each time the common scrolling process is performed, a total sum of the points corresponding to the obtained common game symbols, with reference to the common game symbol value table stored in the common game symbol value storage; and (a4) outputting the identification information and the total sum of the points to the center controller, each time the common scrolling process is performed, and wherein the center controller is programmed to execute the following steps of (b1) to (b3): (b1) outputting the common game start command to the terminal controller, based on the process (a1) executed by the terminal controller; (b2) accumulatively storing the total sum of the points output from the terminal controller in association with the identification information; and (b3) at a predetermining timing, determining a profit awarded to each of the gaming terminals, based on the total sum of the points accumulatively stored in the terminal information memory.
