Table tennis, also known as ping-pong, is a sport in which two players in Singles or four players in Doubles use lightweight and hollow balls and hit them across a table tennis table with rackets. The game is played on a hard and flat table tennis table with a net in the middle. Except when serving, players are required to let the ball bounce once on their own side of the table and then hit it over the net to the opponent's side. Failing to do so results in a point for the opposing player. Generally, table tennis matches require quick speed and agility. Skilled players can control the ball's trajectory through spin, using it to attack the opponent and create advantageous situations for themselves.
