Table tennis, also known as ping-pong and whiff-whaff, 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 small rackets. The game takes place on a hard table divided by a net. Except for the initial serve, the rules are generally as follows: players must allow a ball played toward them to bounce one time 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.
tennis is governed by the worldwide organization International Table Tennis
Federation (ITTF), founded in 1926. ITTF currently includes 226 member
associations. The table tennis official rules are specified in the ITTF
handbook. Table tennis has been an Olympic sport since 1988, with several event
categories. From 1988 until 2004, these were men's singles, women's singles,
men's doubles and women's doubles. Since 2008, a team event has been played
instead of the doubles.
