Table Tennis
Table tennis, also known as ping-pong and whiff-whaff, is a sport in which two or four players hit a lightweight ball, also known as the ping-pong ball, back and forth across a table using small solid rackets. It takes place on a hard table divided by a net. Except for the initial serve, the rules are generally as follows: Players must allow a ball played toward them to bounce once on their side of the table and must return it so that it bounces on the opposite side. A point is 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. Table tennis is governed by the worldwide organization International Table Tennis Federation (ITTF), founded in 1926. ITTF currently includes 226 member associations. The official rules are specified in the ITTF handbook. Table tennis has been an Olympic sport since 1988, with several event ...

Badminton
Badminton is a racquet sport played using racquets to hit a shuttlecock across a net. Although it may be played with larger teams, the most common forms of the game are "singles" (with one player per side) and "doubles" (with two players per side). Badminton is often played as a casual outdoor activity in a yard or on a beach; formal games are played on a rectangular indoor court. Points are scored by striking the shuttlecock with the racquet and landing it within the opposing side's half of the court. Each side may only strike the shuttlecock once before it passes over the net. Play ends once the shuttlecock has struck the floor or if a fault has been called by the umpire, service judge, or (in their absence) the opposing side. The shuttlecock is a feathered or (in informal matches) plastic projectile which flies differently from the balls used in many other sports. In particular, the feathers create much higher drag, causing the shuttlecock to decelerate more rapidly. Sh ...

Tennis
Tennis is a racket sport that is played either individually against a single opponent ( singles) or between two teams of two players each ( doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to manoeuvre the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball validly will not gain a point, while the opposite player will. Tennis is an Olympic sport and is played at all levels of society and at all ages. The sport can be played by anyone who can hold a racket, including wheelchair users. The modern game of tennis originated in Birmingham, England, in the late 19th century as lawn tennis. It had close connections both to various field (lawn) games such as croquet and bowls as well as to the older racket sport today called real tennis. The rules of modern tennis have ...

Volleyball
Volleyball is a team sport in which two teams of six players are separated by a net. Each team tries to score points by grounding a ball on the other team's court under organized rules. It has been a part of the official program of the Summer Olympic Games since Tokyo 1964. Beach volleyball was introduced to the programme at the Atlanta 1996. The adapted version of volleyball at the Summer Paralympic Games is sitting volleyball. The complete set of rules is extensive, but play essentially proceeds as follows: a player on one of the teams begins a 'rally' by serving the ball (tossing or releasing it and then hitting it with a hand or arm), from behind the back boundary line of the court, over the net, and into the receiving team's court. The receiving team must not let the ball be grounded within their court. The team may touch the ball up to three times to return the ball to the other side of the court, but individual players may not touch the ball twice consecutively. ...

Net Sports
Net and wall games are court games where either a net separates the opponents or a wall serves to reflect the ball to the opponent. The object of these games is to hit the ball or bird over the net or against the wall back to the opponent. Play typically begins with one side ''serving'' the ball/bird by initially tossing or releasing it and then hitting it over the net. This then starts a ''rally'', in which the sides alternate hitting the ball/bird over the net. Players then score points whenever the opponent fails to return the ball/bird back over the net. The criteria on what is considered a valid return varies between each sport (such as the number of times the ball may be touched or bounced on a player's side before it must go back over the net). Net and wall games usually include: * racquet sports such as tennis, badminton, pickleball, table tennis, squash, racquetball. * volleyball, footvolley, Jokgu, headis, roundnet or sepak takraw, where players must hit the ball wit ...

Bossaball
''' is a team sport that originated in Brazil and was conceptualised by Belgian Filip Eyckmans in 2005. Bossaball is a ball game between two teams, combining elements of volleyball, football, and gymnastics with music into a sport. It is played on an inflatable court featuring a trampoline on each side of the net. The trampolines allow the players to bounce high enough to spike the ball over the net. The word "bossa", which is sometimes translated as "style, flair or attitude" in Indian Spanish, is commonly associated with Bossa Nova, a samba-influenced type of Brazilian music. The name Bossaball, therefore, expresses the aim to combine sports, music, and positive vibrations. Some other countries where has been introduced include: Brazil, Argentina, Mexico, Turkey, Belgium, Netherlands, Spain, Germany, France, Switzerland, Portugal, Greece, Austria, Italy, Slovenia, Hungary, Czech Republic, Romania, Israel, Egypt, Saudi Arabia, Qatar, Kuwait, Singapore, Chile, Colombia, Ecuad ...

Goal (sport)
In sport, a goal may refer to either an instance of scoring, or to the physical structure or area where an attacking team must send the ball or puck in order to score points. The structure of a goal varies from sport to sport, and one is placed at or near each end of the playing field for each team to defend. For many sports, each goal structure usually consists of two vertical posts, called ''goal posts'', supporting a horizontal ''crossbar''. A ''goal line'' marked on the playing surface between the goal posts demarcates the goal area. Thus, the objective is to send the ball or puck between the goal posts, under or over the crossbar (depending on the sport), and across the goal line. Other sports may have other types of structures or areas where the ball or puck must pass through, such as the basketball hoop. Sports which feature goal scoring are also commonly known as invasion games. In several sports, sending the ball or puck into the opponent's goal structure or area is ...
