Game system

Abstract

In the game system GS, each of the game machines GA,GB which execute the local game transmits the game machine information of itself to the local server GA, the local server GA transmits to the center server CS the group coupling requirement MR 1 including plural pieces of the game machine information received and the group ID. The center server CS couples as the competitors the groups GR 1 ,GR 2 corresponding to at least two group coupling requirements MR 1 ,MR 2 received in the predetermined coupling period, and transmits to each of the game machines GA,GB,GC,GD having been coupled, the coupling notice 40 indicating the coupling result and the net server.

1 . A game system comprising:
 plural local networks;   plural game machines which is connected to each of the plural local networks; and   a center server which communicates with each of the game machines via an open network, in which   each of the game machines is configured to communicate with the other game machine of the other local network via the open network, a local game is executed between the game machines in the local network, and a network battle game is executed between the game machines coupled by the center server by using the open network, wherein   each of the game machines has:   a local function determination portion which determines whether or not the game machine itself is a local server at a moment of starting the local game, the local server being a game server in the local game,   a local server portion which makes the game machine itself function as the local server when it is determined that the game machine itself is the local server by the local function determination portion;   a local client portion which, communicating with the local server portion, makes the game machine itself function as a local client which is a game client in the local game;   a net server portion which, when a coupling notice transmitted from the center server indicates that the game machine itself is a net server which is a game server in the network battle game, makes the game machine itself function as the net server; and   a net client portion which, when the coupling notice from the center server is received, makes the game machine itself function as a net client which is a game client in the network battle game,   the local client portion transmits to the local server portion, the game machine information including at least a game machine ID for identifying the game machine itself,   the local server portion generates and transmits to the center server, a group coupling requirement including a group ID for identifying a group constituted by the game machines which has transmitted the game machine information, and   the net server portion controls progress of the network battle game where the groups battles with each other, by treating as one unit, the game machines correlated to each of the group IDs included in the coupling notice transmitted from the center server, and   the center server has:   a group coupling portion couples as competitors, the groups corresponding to at least two group coupling requirements which have been received during a predetermined coupling period;   a net server determination portion which determines the net server from the game machines coupled by the group coupling portion; and   a coupling notification portion which transmits to each of the game machines, the coupling notice including net server information indicating the game machine determined as the net server, the group IDs the groups of which are coupled, and the game machine information of each of the game machines corresponding to the group IDs.   
     
     
         2 . The game system of  claim 1 , wherein
 the local network is a LAN within a shop, and the group ID is a shop ID for identifying of each shop.   
     
     
         3 . The game system of  claim 2 , wherein
 the game machine information includes player information of a player operating the game machine corresponding to the game machine information, and   the game machine has:   a shop table where the shop ID and a shop name are connected to each other;   a player information obtaining portion which obtains the player information of the player operating the game machine itself; and   a competitor group notification portion which, when the coupling notice is received, based on the game machine information included in the coupling notice received, displays on a game image of the local game, the player information and the shop name as a competitor group.   
     
     
         4 . The game system of  claim 3 , wherein
 after displaying the competitor group, the competitor group notification portion makes at least the local client portion stop functioning to terminate the local game.
