I won by doing nothing as the CPU is complete crap. The cpu will always fail to hit the ball back at you if you're serving and considering the rule of Volley ball is as you get points you get to serve, you're essentially going to be constantly serving. Real Sports Volleyball is way better then is, also the game is false advertising as you play as dudes, the girl in the Bikini is the referee.
