Table tennis, also known as ping pong, is a fast-paced indoor sport played between two or four players. The game involves hitting a lightweight ball back and forth across a table using small paddles. The objective is to score points by making the ball land on the opponent's side of the table in a way that they cannot return it. The game is played on a rectangular table divided by a net. Players must serve the ball by bouncing it on their side first before it crosses the net. Table tennis is governed by the International Table Tennis Federation (ITTF), which sets the rules and organizes competitions worldwide.
