Abstract: Provided is a golf game that is readily intuitively playable by a user. An input reception section receives an operation input indicating a motion of an input device gripped by the hands of the user. A control section controls a motion of a player character in a game space in accordance with the operation input. An image generation section generates a game image. When a golf club held by the player character comes into contact with the ground in the game space, the control section drives a stimulus generation section disposed in the input device to stimulate the user's hands gripping the input device.

Abstract: To enable to accept users' operation inputs complying with users' wishes. In a shot operation of a golf game, a portable digital assistant specifies the first touch point and the last touch point by a user as a first operation point and a third operation point, respectively. And the portable digital assistant specifies the touch point that the moving direction of the Y direction reversed or stopped as a second operation point, by tracing the touch points in reverse order to the order detected each touch point from the last touch point. Thereby, the portable digital assistant can recognize that, in the user's touch operations, the position the user lastly reversed the moving direction of the Y direction or stopped his/her finger or the like was operated while being conscious of as the second operation point. As a result, a shot operation complying with the user's wish can be performed.

Abstract: An object surface is rendered by not only grid lines indicating a slope in the surface of an object, but also by moving objects which move over the object surface with a speed responsive to the slope angle on the object surface, thereby enabling a player to refer to the grid lines and to the movement of a moving object, so as to visually perceive minute slopes and bumps in the object surface.

Abstract: A game apparatus controls a game in which a user-controlled character and an opponent character hit a ball. A serve control unit receives the first input operation from a user and makes the character perform an action of tossing the ball when the character performs a serve. The serve control unit receives the second input operation from the user and makes the character perform an action of the serve. The serve control unit determines a ball power or ball speed in the serve based on the first input operation, and determines a shot type in the serve based on the second input operation. The serve control unit makes the character perform the serve according to the determined ball power or ball speed and the determined shot type.

Abstract: A highly amusing game apparatus is achieved. A game apparatus controls a game where a character operated by a user and an opponent character play ball to compete against each other by hitting a ball. When the user instructs the hitting of the ball by pressing a button of a controller, a hit control unit determines the timing at which the ball is hit by the character and the type of shot according to which button has been pressed by the user. When a parameter indicating the timing of hitting the ball, height of the ball, balance of the character, position of the character and distance between the character and the ball, or athletic ability of the character lies outside a predetermined range in which normal hitting is performable, the hit control unit changes the type of shot from the determined type of shot to another type of shot favorable to the opponent character.

Abstract: A game apparatus controls a game in which a user-controlled character and an opponent character hit a ball. When the user gives an instruction for hitting the ball with a button of a controller, a hit control unit determines on the basis of the type of the button which is pressed by the user a shot when the character hits the ball, calculates the trajectory of the ball hit based on the shot, and displays the flying ball on a screen. A shot display control unit displays the figure marked on the button close to the ball on the screen, as information for specifying the shot.

Abstract: A game device includes: an object arrangement modification unit adapted to acknowledge selection of an object subject to movement from among a plurality of objects arranged in one direction in a game field, and to move the selected object to a position requested by a user; a determination unit adapted to refer to a table storing a proper order of arrangement of the plurality of objects, determine whether objects that should be arranged adjacent to each other are properly placed in adjacent positions, and group those objects that are properly placed in adjacent positions if any. The object arrangement modification unit moves the plurality of objects belonging to a group in a block when the grouped objects are selected.
