Abstract:
1. A computer system comprising: a processor, an operation unit which inputs an operation to a game, a display unit which displays information associated with the game, and a computer-readable storage unit which stores program instructions and data required to execute the game, wherein execution of the program instructions by said processor controls the computer system to: generate display data of falling objects which are displayed to fall from an upper portion to a lower portion in a predetermined display area on the display unit, and storing the display data in the storage unit; read-out the generated display data of the falling objects from the storage unit, and displaying the falling objects to fall from the upper portion to the lower portion in the predetermined display area; change, when the falling objects reach a falling stop position in the display area, the display data to display the falling objects as stop objects whose falling movement stops, and storing the changed display data in the storage unit; designate the predetermined number or less of stop objects in accordance with a designation instruction from the operation unit; and change, when the stop objects are designated, the display data of stop objects to re-arrange positions of the designated stop objects in accordance with a re-arrange instruction from the operation unit, and storing the changed display data in the storage unit; determine whether the re-arranged stop objects and the stop objects which are located around the re-arranged stop objects meet a predetermined ignition condition; calculate, when the ignition condition is met, an impelling force of launched and rising objects formed by the re-arranged stop objects and the stop objects based on the number of the re-arranged stop objects and the stop objects, the impelling force being in a rising direction from the lower portion to the upper portion in the predetermined display area on the display unit and the impelling force defining a rising distance of the launched and rising objects in the rising direction; change, when the ignition condition is met, display data of a plurality of stop objects which meet the ignition condition based on the impelling force to display data that express the launched and rising objects which are launched and rise in the rising direction from the lower portion to the upper portion in the predetermined display area on the display unit, and storing the changed display data in the storage unit; and change, when the launched and rising objects reach a predetermined clear position in the display area, the display data to clear display of the launched and rising objects, wherein the launched and rising objects are launched and rise apart from the rest of the stop objects.
