Table tennis is a sport in which two or four players hit a lightweight ball back and forth using table tennis rackets. The game takes place on a hard table divided by a net. Except for the initial serve, players must allow a ball played toward them only one bounce on their side of the table and must return it so that it bounces on the opposite side. Points are 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. When doing so the hitter has a good chance of scoring if the spin is successful. Table tennis is governed by the worldwide organization International Table Tennis Federation (ITTF), founded in 1926. ITTF currently includes 218 member associations. The table tennis official rules are specified in the ITTF handbook. Since 1988, table tennis has been an Olympic sport, with several event categories. In particular, 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. -------------------------------------------------
The international rules specify that the game is played with a light 2.7 gram, 40 mm diameter ball. The rules say that the ball shall bounce up 24–26 cm when dropped from a height of 30.5 cm on to a standard steel block thereby having a coefficient of restitution of 0.89 to 0.92. The 40 mm ball was introduced after the 2000 Olympic Games. However, this created some controversy as the Chinese National Team argued that this was merely to give non-Chinese players a better chance of winning since the new type of balls has a slower speed, while at that time most Chinese players were playing with fast attack and smashes. A 40 mm table tennis ball is slower and spins less than the original 38 mm (1.5 inch) one. The ball is made of a high-bouncing air-filledcelluloid or similar plastics material, colored white or orange, with a matte finish. The choice of ball color is made according to the table color and its surroundings. For example, a white ball is easier to see on a green or blue table than it is on a gray table. Stars on the ball indicate the quality of the ball. Three stars indicate that it is of the highest quality, and is used in official competition. Table

The table or playing surface is divided into two halves by a 15.25 cm (6 inch) high net. An ITTF approved table surface must be in a green or blue color.Concrete tables with a steel net are sometimes available in outside public spaces, such as parks. Racket
Main article: Table tennis racket
Players are equipped with a laminated wooden racket covered with rubber on one or two sides depending on the grip of the player. The official ITTF term is "racket", though "bat" is common in Britain, and "paddle" in the U.S. The wooden portion of the racket, often referred to as the "blade", commonly features anywhere between one and seven plies of wood, though cork, glass fiber, carbon fiber, aluminum fiber, and Kevlar are sometimes used. According to the ITTF regulations, at least 85% of the blade by thickness shall be of natural wood. Common wood types include Balsa, Limba, and Cypress or "Hinoki," which is popular in Japan. The average size of the blade is about 6.5 inches (16.5 cm) long and 6 inches (15 cm) wide. Although the official restrictions only focus on the flatness and rigidness of the blade itself, these dimensions are optimal for most play styles. Table tennis regulations allow different surfaces on each side of the racket. Various types of surfaces provide...
