Game service system for using near wireless communication

A system for providing a game service through NFC(Near Field Communication) is provided to prevent unnecessary memory use and distribute load applied to a host terminal by assigning priority according to order of guest terminals joining in a game, and transceiving data between the host terminal and the guest terminal sequentially according to the priority. An NFC module(201) transceives data with an NFC communicator of guest terminals. A game generator(203) provides a list of games stored in a game database(202) and access/executes game data corresponding to game selection information by a game generation command. A game joining information collector(204) provides game generation information to the neighboring guest terminals through the NFC module, and receives or collects a game joining request from the guest terminals. A priority assigner(205) assigns priority to each guest terminal. A game progress information collector(206) receives or collects game progress information of each guest terminal according to the priority. A game progress manager(207) activates the game by a game execution command, collects/reflects the game progress information to the game, and transmits the game information reflecting the game progress information to the guest terminals.
