How to play doubles in ping pong
Decide who serves first.
This can be determined in many ways--you can flip a coin or you can volley. To volley is just to toss the ball and play it until someone scores if you score then it is your serve, but when you volley the ball has to be hit three times in the match before some scores.

Possible answers:
(1). If you regularly serve, or hold a double serve, then it is your serve which counts as your serve to play doubles. To volley is about shooting right up the line.;
(2). Tap the three dots either near the bottom of the ball to flip a coin. If trying to volley with an opponent you might toss the ball so that you get two weighted " dies " and then try to knock it apart.;
(3). Serve from any side of your table. Hit the ball on your side once and have the ball go over the net to hit their side.;
(4). Decide where to aim for by setting an internal time clock and marking the amount of times your serve should be tossed and then selecting your shots. It is your shot, so give it your full attention.;
(3).
