In table tennis, two players or pairs of players face each other across a table that is 2.74 meters long and 1.525 meters wide. Before the match begins, a coin toss determines who serves first and which side of the table to play on. During the match, players must serve the ball from their own side of the table and their opponent must return the ball to the other side. If a player fails to return the ball or the ball touches any object (including the table, floor, racket, or body) after crossing the net, their opponent scores a point. The winner of each game is the first player to reach 11 points, and matches are typically played in a best-of-five or best-of-seven format. Players can use a variety of techniques and tactics during the match, including serving, receiving, forehand, backhand, spin, and more.
