Gaming system having a plurality of gaming machines linked by network and control method thereof

1. A gaming system comprising:

a plurality of gaming machines, each including a controller;

a control device including a processor;

a network enabling communication between said plurality of gaming machines and said control device; and

a storage device which stores a plurality of individual cumulative values,

wherein

the plurality of individual cumulative values are associated with a plurality of predetermined percentages and a plurality of specific values, respectively,

each of the plurality of predetermined percentages differs from the other predetermined percentages,

each of the plurality of specific values differs from the other specific values,

each controller is programmed to execute processing of:

(a) transmitting number-of-game media information relating to a number of betted game media to said control device,

said processor is programmed to execute processing of:

(A) cumulatively counting a part of the number of betted game media according to the plurality of predetermined percentages, as the plurality of individual cumulative values, triggered by a receipt of said number-of-game media information from one of said plurality of gaming machines;

(B) determining whether or not any one of said plurality of individual cumulative values cumulatively counted in said processing (A) has reached an associated one of the plurality of specific values; and

(C) transmitting a common-game execution signal to said one of said plurality of gaming machines to execute a common game, after it is determined in said processing (B) that said one of the plurality of individual cumulative values has reached the associated one of the plurality of specific values,

each controller is further programmed to execute processing of:

(b) executing the common game after receiving said common-game execution signal from said control device; and

(c) transmitting common-game result information determined based on a result of the common game executed in said processing (b), to said control device, and

said processor is further programmed to execute processing of:

(D) selecting a single gaming machine out of the plurality of said gaming machines, based on said common-game result information; and

(E) paying out game media, in a number corresponding to said one of the plurality of individual cumulative values, from the single gaming machine selected in said processing (D).

2. The gaming system according to claim 1 ,

wherein

said control device further includes an input device, and

said processor is further programmed to execute processing of:

(F) changing said plurality of predetermined percentages and/or said plurality of specific values in accordance with an input from said input device.

3. The gaming system according to claim 1 ,

wherein

each of said plurality of gaming machines further includes an input device, and

each controller is further programmed to execute processing of:

(d) changing said plurality of predetermined percentages and/or plurality of specific values in accordance with an input from said input device.

4. The gaming system according to claim 1 ,

wherein

each of said plurality of gaming machines includes a symbol display capable of variably displaying symbols;

said processor is further programmed to execute:

in said processing (A), cumulatively counting another part of the number of betted game media as a solo-game cumulative value for a solo game; and

each controller is further programmed to execute processing of:

(d) executing the solo game for stop-displaying said symbols to said symbol display after variably displaying said symbols, based on a solo-game program; and

(e) paying out game media, in a number corresponding to said solo-game cumulative value, when said symbols are stop-displayed in a specific state in said solo game, and when said solo-game cumulative value has reached a second specific value which is larger than said specific value.

5. The gaming system according to claim 4 ,

wherein

each controller is further programmed to execute:

in the processing (d), executing the solo game for stop-displaying said symbols to said symbol display after variably displaying said symbols, based on a first symbol array table for determination of said symbols stop-displayed, and

in the processing (b), as the common game, stop-displaying said symbols on said symbol display after variably displaying said symbols, based on a second array table for determination of said symbols stop-displayed, not to stop-display said symbols in said specific state.

6. The gaming system according to claim 1 ,

wherein,

the storage device stores a plurality a the plurality of individual cumulative values corresponding to a plurality of common games, respectively;

the plurality of common games are associated with the plurality of predetermined percentages and the plurality of specific values, respectively;

in the processing (B), the processor is programmed to execute processing of determining whether or not any one of said plurality of individual cumulative values cumulatively counted in said processing (A) has reached an associated one of the plurality of specific values of an associated one of the plurality of common games;

in the processing (C), the processor is programmed to execute processing of transmitting the common-game execution signal to said one of said plurality of gaming machines to execute the associated one of the plurality of common games, after it is determined in said processing (B) that said one of the plurality of individual cumulative values has reached the associated one of the plurality of specific values;

in the processing (b), each controller is programmed to execute processing of executing the associated one of the plurality of common games after receiving said common-game execution signal from said control device; and

in the processing (c), each controller is programmed to execute processing of transmitting common-game result information determined based on a result of the associated one of the plurality of common games executed in said processing (b), to said control device.
