PROBLEM TO BE SOLVED: To provide a shooting device and an arithmetic method for making the invalidation time of a target different depending on a part where a bullet hits and setting extinction time short in the case of hitting the head or the like especially compared to the case of hitting other parts. SOLUTION: In this shooting game device, shooting is performed to the target displayed on a display by using a shooting device. It is provided with a target invalidation time decision part 116 for detecting to which part of the target an impact point by shooting belongs and deciding the length of the invalidation time for switching the target from a valid state to an invalid state corresponding to the detected part and a target invalidation arithmetic part 117 for switching the target from the valid state to the invalid state based on the target invalidation time. |
