Decide who will serve first. There are numerous ways to decide, including flipping a coin or spinning a racquet. (Call heads or tails or choose insignia up or down.)
Step2
Serve the ball, accumulating points until the other person/team wins a rally or until you fail to play a serve legally. Each time the rally ends in your favor you earn a point. When the receiving team wins a rally, it's called a sideout (similar to volleyball).
Step3
Announce the score each time before serving the ball.
Step4
Continue until one person/team reaches 15 points. A one-point advantage constitutes a win (15-14).
Step5
Allow the person/team that lost the first game to open service for the second game.
Step6
Play the third game to 11 points if necessary. The person/team that accumulated the most points in the first two games gets to serve first in the third game.
Tips & Warnings
Unless you're playing in a sanctioned event, feel free to play to any number both sides agree to.
Announcing the score out loud before each serve will alleviate any discrepancies during the game.
If you have any condition that would impair or limit your ability to engage in physical activity, please consult a physician before attempting this activity.
