1. GAMES ARE PLAYED TO 11 POINTS
A Game is played to 11 points. A Game must be won by two points. A Match is generally the best three of five Games.
2. ALTERNATE SERVES EVERY TWO POINTS
Each side of the table alternates serving two points at a time. EXCEPTION: After tied 10-10 (“deuce”), service alternates at every point. Can you lose on a serve in ping pong? Yes! There is no separate rule for serving on Game Point.
3. TOSS THE BALL STRAIGHT UP WHEN SERVING
How do you serve the ball in ping pong? Hold the ball in your open palm, behind your end of the table. Toss at least 6” straight up, and strike it on the way down. It must hit your side of the table and then the other side. NOTE: Once the ball leaves the server’s hand it is in play, and so counts as the receiver’s point if the ball is missed or mis-hit.
4. THE SERVE CAN LAND ANYWHERE IN SINGLES
There is no restriction on where the ball lands on your side or your opponent’s side of the table. It can bounce two or more times on your opponent’s side (if so, that’s your point), bounce over the side, or even hit the edge.
5. DOUBLES SERVES MUST GO RIGHT COURT TO RIGHT COURT
The serve must bounce in the server’s right court, and receiver’s right court (NOTE: landing on center line is fair). Doubles partners switch places after their team serves twice.
