Abstract: Progression of a game executed at a mobile terminal is changed in response to the current location of the mobile terminal. A portable telephone set receives a control signal transmitted via radio from a base station controlling the radio area in which the portable telephone set is currently located. Then, the received control signal is demodulated to detect the base station ID code, which is in turn stored in an ID code storage area. The update processing of the base station ID code is successively carried out during the waiting time and a latest base station ID code is stored in the ID code storage area. Then, in the course of the progression of a game, enemy characters to combat, items to be generated, and the branching of the game scenario are controlled in accordance with the value of the base station ID code stored in the ID code storage area.

Abstract: Progression of a game executed at a mobile terminal is changed in response to the radiowave reception intensity of radio signals received by the mobile terminal. During the course of the progression of a game, enemy characters to combat, items to be generated, and the branching of the game scenario are controlled in accordance with the received signal intensity.

Abstract: During execution of a game program, in response to a manipulation by a player, each game terminal requests a situation-solving information server to supply situation-solving information. In sending such a request, each game terminal also sends game progress information such as a current scene (map No.), a standstill time at the same scene, and the number of times of requesting of situation-solving information for the same scene. In response to the request from each game terminal, the situation-solving information server judges the level of each player based on the game progress information, extracts situation-solving information whose content is suitable for the level, and supplies it to the request source game terminal. Each game terminal displays the situation-solving information thus received.
