Table Tennis

Table tennis, is a sport in which two or four players hit a lightweight ball, also known as the ping-pong ball, back and forth across a table using a small racket (also called a bat or paddle). The game takes place on a hard table divided by a net. Table tennis is also known as ping-pong and whiff-whaff. 

Except for the initial serve, the rules are generally as follows: players must allow a ball played toward them to bounce once on their side of the table and must return it so that it bounces on the opposite side at least once. A point is scored when a player fails to return the ball within the rules. Play is fast and demands quick reactions. Spinning the ball alters its trajectory and limits an opponent's options, giving the hitter a great advantage.
