The present invention relates to a shuttlecock for a racket game in a small indoor space. The shuttlecock weighs 1.5-3g, and has a base having a diameter of 16-23mm and a vertical length of 14-21mm, and 10-14 feathers having a vertical diameter of 40-60mm, wherein the vertical length of the shuttlecock from the lower end of the base to the upper end of the feathers ranges from 50 to 80mm. The shuttlecock allows the flying distance and height thereof to be reduced, and thus a game can be played even in a small space. The shuttlecock is light, and thus elderly people and children can play a game with ease and the likelihood of joint pain can be prevented. As the flying distance of the shuttlecock is shortened, the shuttlecock can travel back and forth more frequently, thereby increasing amusement.; A racket game playing using the present invention is a step-based exercise which increases the amount of exercise, and is easy to play. Therefore, the racket game is suitable for development into a national sport.
