Shooting, as a kind of sport, has a long history in human civilization. Maybe one of the highest honors for shooting athletes is to win the gold medal in the Olympic Games, you will be an Olympic athlete pursing the great honor in shooting history. You have ten shots and each lasts for 5 seconds. That?s to say if you don?t shoot within the given time, you will waste one chance. Try to hit the center of the target because different rings mean different scores. Your final points are the summation of every round. Good luck!
