Patent ID: 6932699

Claim:
A game device, for allowing development of a game involving an expansion/contraction object region included in a base region expanded or contracted by a player, comprising: first cell attribute storage means for storing a cell attribute representing a positional relationship of the expansion/contraction object region corresponding to each cell constituting the base region; base region display means for displaying the base region on a game screen based on a cell attribute of each cell constituting the base region stored in the first cell attribute storage means; second cell attribute storage means for storing cell attributes representing a relationship of a closed region for expansion or contraction corresponding to each cell constituting the closed region for expansion or contraction; expansion/contraction mark display means for displaying an expansion/contraction position mark representing a position for adding the closed region for expansion or contraction to the expansion/contraction object region or a position for removing the closed region for expansion or contraction from the expansion/contraction object region on the game screen; position changing means for changing a relative position of the expansion/contraction position mark with respect to the base region in accordance with a command from a player, so as to generate correspondence between each cell constituting the base region and each cell constituting the closed region for expansion/contraction; new cell attribute derivation means for deriving new cell attributes for each cell constituting the base region based on cell attributes of each corresponding cell; and base region re-display means for displaying the base region on the game screen based on the derived new cell attributes.
