Gaming machine and game control method thereof, capable of executing common game corresponding to the number of executed base games

1. A gaming machine, comprising:

a plurality of game terminals having a terminal controller and an input device enabling external input; and

a center controller connected to the game terminals to enable communication therewith,

the terminal controller being programmed to execute:

processing of executing a base game by inputting a start operation of the input device; and

processing of executing a common game by a common game start command from the center controller,

the center controller being programmed to execute:

in a case where a number of times of the base game executed at any of the plurality of game terminals reaches a first predetermined number of trigger games, processing of checking whether each of the plurality of game terminals meets a common game running condition;

processing of checking progressing situation of the base game at a game terminal that meets the common game running condition;

processing of determining an output timing according to a checking result of the progressing situation of the base game at the game terminal that meets the common game running condition; and

processing of outputting the common game start command at the output timing to the game terminal that meets the common game running condition,

wherein the game terminal that meets the common game running condition executes the common game after receiving the common game start command and game terminals that are active and do not meet the common game running condition execute the base game and

wherein the common game running condition for a game terminal is met when a number of base game played on the game terminal reaches a second predetermined number.

2. The gaming machine of claim 1 , wherein the center controller executes processing of outputting the common game start command to a game terminal meeting the common game running condition after the common game has completed, in a case where a number of times of base game executed at any of the game terminals other than the game terminals executing the common game reaches a predetermined number of trigger game.

3. The gaming machine of claim 1 , wherein the center controller executes processing of outputting the common game start command to a game terminal meeting the common game running condition after elapse of a predetermined time, after a number of times of base game executed at any of the plurality of the game terminals has reached a predetermined number of trigger games.

4. The gaming machine of claim 1 , wherein each of the plurality of game terminals comprises:

a first display device for displaying the base game;

a second display device for displaying the common game and displaying a total amount of prize money by a number of credits;

a third display device for displaying information indicating rules of the base game and/or the common game; and

a notification device for visually notifying at least start of the common game to a player.

5. The gaming machine of claim 1 , wherein the common game is a craps game.

6. A game control method of a gaming machine, the gaming machine comprising:

a plurality of game terminals having a terminal controller and an input device enabling external input; and

a center controller connected to the game terminal to enable communication therewith,

the terminal controller executing the steps of:

executing a base game by inputting a start operation of the input device, and executing a common game by a common game start command from the center controller; and

the center controller executing the step of:

in a case where a number of times of the base game executed at any of the plurality of game terminals reaches a first predetermined number of trigger games, checking whether each of the plurality of game terminals meets a common game running condition;

checking progressing situation of the base game at a game terminal that meets the common game running condition;

determining an output timing according to a checking result of the progressing situation of the base game at the game terminal that meets the common game running condition; and

outputting the common game start command at the output timing to the game terminal that meets the common game running condition,

wherein the game terminal that meets the common game running condition executes the common game after receiving the common game start command and game terminals that are active and do not meet the common game running condition execute the base game and

wherein the common game running condition for a game terminal is met when a number of base game played on the game terminal reaches a second predetermined number.

7. The gaming machine of claim 1 , wherein the game terminals that are active and do not meet the common game running condition are able to meet the common game running condition afterward by making additional bet.

8. The gaming machine of claim 1 , wherein, in the processing of checking progressing situation of the base game at a game terminal that meets a common game running condition, in a case where any of the plurality of game terminals executes a bonus game as the base game, the center controller outputs the common game start command after elapse of a predetermined time, and in a case where any of the plurality of game terminals executes neither the bonus game nor the common game, the center controller instantly outputs the common game start command without waiting elapse of a predetermined time.

9. The game control method of claim 6 , wherein, in the step of checking progressing situation of the base game at a game terminal that meets a common game running condition, in a case where any of the plurality of game terminals executes a bonus game as the base game, the center controller outputs the common game start command after elapse of a predetermined time, and in a case where any of the plurality of game terminals executes neither the bonus game nor the common game, the center controller instantly outputs the common game start command without waiting elapse of a predetermined time.

10. The gaming machine of claim 1 , wherein, the second predetermined number is set at a greater value as the first predetermined number of trigger games increases and is set at a value equal to or smaller than the first predetermined number of trigger games.

11. The game control method of claim 6 , wherein, the second predetermined number is set at a greater value as the first predetermined number of trigger games increases and is set at a value equal to or smaller than the first predetermined number of trigger games.

12. The gaming machine of claim 1 , wherein, each of the plurality of game terminals comprises a first display unit displaying the first predetermined number and a second display unit displaying the second predetermined number.

13. The gaming machine of claim 8 , wherein, the game terminals that are active and do not meet the common game running condition display an inquiry of participation in the common game and in a case where an input for participation in the common game is received, the game terminal receiving the input for participation displays an explanation of a participation method.
