7. The game system of claim 1 , wherein the circuitry of the game server is configured to determine whether a player differing from the player of the terminal device was playing the game during a period in which the communication with the terminal device was being disconnected,

wherein, when the game that was being played at the terminal device is not in the locked state in a case in which the disconnected communication has been restored, and when the circuitry of the game server has determined that the game that was being played at the terminal device during the period of the disconnected communication was not played by the other player, the circuitry of the game server is configured to update game data of the game that was being played at the terminal device for which the communication has been restored and also to update credit information corresponding to the player of the terminal device and set the game that is played at the terminal device to a locked state.

8. A game server for managing a game played at plural terminal devices with which the game server is communicable, the game server comprising circuitry configured to:

store game data corresponding to a game and store, in association with each of the players, credit information that varies depending on consumption of credit as exchange for a play in a game or on awarding of a game value in accordance with a result of a game in a storage device;

set a game played at one of the terminal devices to be in a locked state, thereby prohibiting the play of the game at another of the terminal devices;

periodically perform communication with the terminal device at which the game is progressing, and periodically receive game data of the game from the terminal device, to update game data that is stored in the storage device and that corresponds to the game data received from the terminal device in accordance with the progress of the game that is played in the terminal device, followed by again updating the game data in accordance with the progress of the game that is played at another of the terminal devices; and

remove the locked state of the game when the game ends at the terminal device or when the communication is disconnected, thereby permitting the play of the game at another of the terminal devices,

wherein, when the game that was being played at the terminal device is in the locked state in a case in which the disconnected communication has been restored, the circuitry of the game server is further configured not to update game data of the game that was being played at the terminal device for which the communication has been restored, but to update credit information corresponding to a player of the terminal device in accordance with changes in the amount of credit in a play while the communication was being disconnected.

9. A control method for a game server for communicating with plural terminal devices at which a game can be played by a player, the method comprising:

storing game data corresponding to a game and storing, in association with each of the players, credit information that varies depending on consumption of credit as exchange for a play in a game or on awarding of a game value in accordance with a result of a game in a storage device;

setting a game played at one of the terminal devices to be in a locked state, thereby prohibiting the play of the game at another of the terminal devices;

periodically performing communication with the terminal device at which the game is progressing, and periodically receiving game data of the game from the terminal device, to update game data that is stored in the storage device and that corresponds to the game data received from the terminal device in accordance with the progress of the game that is played in the terminal device followed by again updating the game data in accordance with the progress of the game that is played at another of the terminal devices; and

removing the locked state of the game when the game ends at the terminal device or when the communication is disconnected, thereby permitting the play of the game at another of the terminal devices,

wherein, when the game that was being played at the terminal device is in the locked state in a case in which the disconnected communication has been restored, not updating game data of the game that was being played at the terminal device for which the communication has been restored, but updating credit information corresponding to a player of the terminal device in accordance with changes in the amount of credit in a play while the communication was being disconnected.

10. A non-transitory computer recording readable medium having stored thereon a program for executing a method in a computer for communicating with plural terminal devices at which a game can be played by a player, the method comprising:

storing game data corresponding to a game and storing, in association with each of the players, credit information that varies depending on consumption of credit as exchange for a play in a game or on awarding of a game value in accordance with a result of a game in a storage device;

setting a game played at one of the terminal devices to be in a locked state, thereby prohibiting the play of the game at another of the terminal devices;
