A shuttlecock to be struck by a racquet has a shaped base and a number of separate flexible tail portions secured to the base. The base also has a piston element therein, so as to form a shuttlecock that has a varying movement or erratic flight performance when struck. A game is played by hitting the shuttlecock through a marked-off area called a flyzone. Scoring of a game or sets is determined by the elapsed time the shuttlecock is hit back and forth by at least two players through field goals formed at opposite ends of the marked-off area.
