Patent ID: 8840467

Claim:
A game control method, which is used in a server apparatus which comprises a processor and a storage device and is configured to communicate with a plurality of mobile terminals, the method being required to control each mobile terminal to individually execute a game in which a container that contains an item in advance is obtained by moving a display range for each mobile terminal in a virtual space based on an operation of a user of the mobile terminal or a container that contains an item in advance is obtained as a present from another mobile terminal, and points corresponding to the container and the item are accumulated, the method comprising: a step of controlling the processor to store, for each user, user identification information required to identify the user, terminal identification information required to identify the mobile terminal and the points in the storage device in association with each other; a first point increase step of controlling the processor to increase, when the container included in the display range is obtained based on an operation of the user of the mobile terminal, the points stored in the storage device in association with the terminal identification information of the mobile terminal; an opening step of controlling the processor to open, when opening of the container obtained by movement of the display range or as a present from another mobile terminal is selected based on an operation of the user of the mobile terminal, the container at predetermined success percentages to obtain an item from the opened container and to write the obtained item in the storage device in association with the terminal identification information of the mobile terminal, or to fail to open the container based on failure percentages correlated to the success percentages; a present step of controlling the processor to transmit, when the obtained container or the container, which has failed to be opened, is presented to a user of another mobile terminal based on an operation of the user of the mobile terminal, screen data indicating a present of the container to the other mobile terminal; and a second point increase step of controlling the processor to convert an item stored in the storage device in association with the terminal identification information of the mobile terminal into points based on an operation of the user of the mobile terminal, and to increase the points stored in the storage device in association with the terminal identification information by converted points.
