Players A and B are at the baseline, opposite sides; player C is waiting for his turn at one of the net posts.
A and B play the point out; it begins with a courtesy feed by either one of the players. The winner remains on the court, the player who loses is replaced by C.
The next point begins with a courtesy feed by the player who just stepped up to play.
The winner stays put and the one who loses gets replaced by the substitute player; and so on.
Scoring: Every time a player wins a point, they count it. Add up the points until one wins 11.
Note: This is a fun, competitive game which, if done at fast pace (players moving in and out quickly), it can be a great work-out.
