The present invention provides local information indispensable for travelers or the like and serves as a guide satisfying the travelers' tastes at places where the travelers are staying on their journeys. Positional information is detected from an information request signal transmitted from a cellular terminal, and when the cellular terminal is within a specific area, information corresponding to the specific area is delivered to the cellular terminal in a form of a quiz or a game. Further to a response from the cellular terminal for the information delivered to the cellular terminal, a result record is delivered, and when the cellular terminal is not within the specific area, information other than that corresponding to the specific area is delivered. When giving a point according to the result, a point for the information corresponding to the specific area is set at a higher value as compared to that for the information other than that corresponding to the specific area.
