摘要

To provide a network game system for switching a server-client machine without deteriorating the excitement of a game. A network game system (10) causes each of a plurality of game machines (12) to operate as a client and at least one of the plurality of game machines (12) to also operate as a server, thereby providing a game to be played by the players of the plurality of game machines (12). A game play evaluation value calculation unit (40) calculates a play evaluation value corresponding to each of the plurality of game machines (12) during a game. In the case where a predetermined switching determination time arrives during the game, a server switching unit (52) switches the game machine (12) operating as the server from the game machine (12) currently operating as the server to another game machine (12) of the plurality of game machines (12), based on the evaluation value calculated by the play evaluation value calculation unit (40).
