Association football, more commonly known as football or soccer, is a team sport played between two teams of 11 players each, who almost exclusively use their feet to propel a ball around a rectangular field called a pitch. The objective of the game is to score more goals than the opposing team by moving the ball beyond the goal line into a rectangular-framed goal defended by the opposing team. Traditionally, the game has been played over two 45-minute halves, for a total match time of 90 minutes. With an estimated 250 million players active in over 200 countries and territories, it is the world's most popular sport.
Gaelic football, commonly known as simply Gaelic, GAA, or football, is an Irish team sport. A form of football, it is played between two teams of 15 players on a rectangular grass pitch. The objective of the sport is to score by kicking or punching the ball into the other team's goal or between two upright posts above the goal and over a crossbar 2.5 metres above the ground.
In many team sports that involve scoring goals, the goalkeeper is a designated player charged with directly preventing the opposing team from scoring by blocking or intercepting opposing shots on goal. Such positions exist in bandy, rink bandy, camogie, association football, Gaelic football, international rules football, floorball, handball, hurling, field hockey, ice hockey, roller hockey, lacrosse, ringette, rinkball, water polo, and shinty, as well as in other sports.
Futsal is a football-based sport played on a hardcourt like a basketball court, smaller than a football pitch, and mainly indoors. It has similarities to five-a-side football and indoor football.
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. Sports which feature goal scoring are also commonly known as invasion games.
Indoor soccer or arena soccer is a five-a-side or six-a-side version of minifootball, derived from association football and adapted to be played in walled hardcourt indoor arena. Indoor soccer, as it is most often known in the United States and Canada, was originally developed in these two countries as a way to play soccer during the winter months, when snow would make outdoor play difficult. In those countries, gymnasiums are adapted for indoor soccer play. In other countries the game is played in either indoor or outdoor arenas surrounded by walls, and is referred to by different names.
Gridiron football, also known as North American football, or in North America as simply football, is a family of football team sports primarily played in the United States and Canada. American football, which uses 11 players, is the form played in the United States and the best known form of gridiron football worldwide, while Canadian football, which uses 12 players, predominates in Canada. Other derivative varieties include arena football, flag football and amateur games such as touch and street football. Football is played at professional, collegiate, high school, semi-professional, and amateur levels.
International rules football is a team sport consisting of a hybrid of football codes, which was developed to facilitate international representative matches between Australian rules football players and Gaelic football players.
Five-a-side football is a version of minifootball, in which each team fields five players. Other differences from association football include a smaller pitch, smaller goals, and a reduced game duration. Matches are played indoors, or outdoors on artificial grass pitches that may be enclosed within a barrier or "cage" to prevent the ball from leaving the playing area and keep the game constantly flowing.
Beach soccer, also known as beach football, sand football or beasal, is a variant of association football played on a beach or some form of sand.
Speedball is a fast-paced sport that combines many aspects of other sports. Points are scored by throwing or kicking the ball into the opposing goal. It is played with two teams of at most five, each with one goalie on a basketball court or soccer field.
In the sport of association football, fouls and misconduct are acts committed by players which are deemed by the referee to be unfair and are subsequently penalised. An offence may be a foul, misconduct or both depending on the nature of the offence and the circumstances in which it occurs. Fouls and misconduct are addressed in Law 12 of the Laws of the Game. A foul is an unfair act by a player, deemed by the referee to contravene the game's laws, that interferes with the active play of the match. Fouls are punished by the award of a free kick to the opposing team. A list of specific offences that can be fouls are detailed in Law 12 of the Laws of the Game ; these mostly concern unnecessarily aggressive physical play and the offence of handling the ball. An infringement is classified as a foul when it meets all the following conditions:
- It is committed by a player ;
- It occurs on the field of play;
- It occurs while the ball is in play;
- It is committed against an opponent.
Australian rules football and Gaelic football are codes of football, from Australia and Ireland respectively, which have similar styles and features of play. Notably both are dominated by kicking from the hand and hand passing as well as rules requiring the ball is bounced by a player running in possession, both have a differentiated scoring system, with higher and lower points values for different scoring shots, both have no offside rule, and both allow more physical contact and players on the field than other football codes - 15 in gaelic football, 18 in Australian Rules.
Circle rules football, commonly referred to as circle rules, is a team sport played between two teams of six with a large spherical ball similar to a stability ball. Invented in New York City in 2006, the sport is currently played in cities across the United States, as well as in several international locations.
