Game device, game control program, and method for controlling golf game

A game device having a processor for executing playing a golf game, the game device comprising:

• an input device comprising at least one button located on a housing of the game device;
• a tri-axial gyro sensor for measuring an orientation of the game device when held by a user;
• a display device for displaying an image of a golf course of the golf game on the display device;
• wherein the processor determines a success of a power shot in the golf game by executing the steps of:
• a. acquiring a first input instruction from the input device by the user using the processor;
• b. acquiring a second input instruction from the input device after the first input instruction within a first predetermined time period using the processor;
• c. if the second input instruction occurred within the first predetermined time period, acquiring a first orientation of the game device from the tri-axial gyro sensor when the second input instruction is received;
• d. setting the first orientation as a reference orientation;
• e. receiving a third input instruction from the input device within a second predetermined time period after the second input instruction;
• f. if the third input instruction occurred within the second predetermined time period, acquiring a second orientation of the game device from the tri-axial gyro sensor when the third input instruction is received;
• g. measuring an angular displacement of the game device between the first orientation and the second orientation;
• and
• h. if the angular displacement is greater than a first angular displacement and within a range of a second angle, executing the power shot by displaying a character performing the power shot on the display device.
