Stand behind the service line and serve diagonally. (The returner may stand wherever they like.) Two serves as in tennis.
The server must first bounce the ball, then hit it below waist level. Server must keep at least one foot on the ground when hitting the serve and feet may not touch/cross the service line while serving. The ball must bounce in the service box diagonally opposite before being hit by the returner.
If it bounces in the box and hits the wire mesh fencing before crossing the service line (on the returner’s side), it’s a fault. If the ball hits the net and bounces in the box it’s a let – unless it touches the wire mesh fencing before the 2nd bounce.
