Table tennis game is played on a table that is nine feet long, five feet wide and 30 inches in thickness. The surface of the table is wood which is coated by a layer of low friction polymer. The table is divided into two equal halves by a net that is six inches in height. The table must be either green or blue in color. The paddles are roughly six and half inches in length and six inches in width, at the face. There is also a handle which players use to wield the racquet. The ball is 40 mm in thickness and must be either white or orange in color, depending upon the table color. Table tennis rules have been changed in 2001 and the current rules specify that a game is concluded when one player reaches 11 points.
However, a two point separation must be there between the opponents for the game to conclude. So, after the points reach 10 each, the players continue to play till a two point difference is achieved. A match constitutes of seven such games in all but can be concluded whenever one player wins four games. Each game has to be alternately served out by both the players; each player serves for two points at a time, immaterial of who wins the point. If the game reaches a stage where both players are on 10 points each, the serve alternates for every point till a two point difference is achieved. The serve must be made above the table surface and the ball must not be concealed at any time during. During the serve, the ball must be tossed at least six inches above the surface of the table before it is hit by the racquet of the server. A legal serve must bounce on the server’s table area before bouncing on the opponents table half and the ball must not touch the net during the serve. The rally constitutes the return and the subsequent exchange of shots. During the rally, the ball must bounce in the opponent’s table area directly after hitting the player’s racquet. The rally is concluded when either when the ball goes out of the play area without touching the opponent’s table half or when the player fails to retrieve the opponents shot. These are the international rules that are commonly applied all across the world. However, adaptations of the rules, especially for the aspects of serving techniques and ball sizes are used in some places.
