Futsal began in the 1930s in South America as a version of association football, taking elements of its parent game into an indoor format so players could still play during inclement weather. Over the years, both sports have developed, creating a situation where the two sports share common traits while also hosting various differences.
The Laws of the Game for each sport both have 17 laws, all of which cover the same topics, although with some variations in certain areas.
"Official" assistant Referees exist in higher level futsal matches, serving as replacement referees and either third referees (generally overseeing substitutions and time-outs) or as timekeepers (keeping a record of the time and goals scored at the discretion of the referee.)
The duration of the match can vary depending on league variations. However, at the highest levels of play, both sports are separated into two standardized halves of equal time, allowing for extra time to be played at the referee's discretion to make up for any time wasted.
In futsal, that standardized time for each half is 20 minutes and in association football, the standardized time for each half is 45 minutes.
Also in futsal, teams are allowed to stop the clock once per half, something not allowed in association football.
Unlike in association football, futsal keeps track of fouls that award a direct free kick, also known as "accumulated foul."
Upon the sixth accumulated foul in a half and every accumulated foul after the sixth, the free kick is generally taken from what is known as the "second penalty mark,"
After the sixth accumulated foul, the advantage rule generally no longer applies, with referees granting an immediate free kick outside of very clear goal scoring opportunities.
If the infringement takes place in the attacking half of the pitch, the fouled player may take the free kick from the spot of the infringement or from the second penalty mark, which on a regulation futsal pitch is 10 metres from the goal (the penalty mark is six metres from the goal.)
Unlike a penalty kick, the goalkeeper is required only to stay 5 metres from the spot of the free kick and does not have to stay on the goal line until the ball is kicked. The player kicking the ball must also shoot at the goal and all other players must stay behind the ball until the ball is kicked.
In association football, a player is an offside position if they are beyond the half-line, beyond the second to last defender and beyond the ball at the moment when their teammate touches the ball, excluding when the teammate is engaged in a goal kick, throw-in, or corner kick.
They are committing an infringement if they are in an offside position and are interfering with an opponent, interfering with play or gaining an advantage from being in an offside position.
In futsal, there is no comparable offside rule, although a portion of the Laws of the Game is dedicated to indicating that there is no offside rule.
Although in both sports, the referee has discretion over which players can or cannot come into the pitch, but in futsal substitutions can happen during play provided that players come on and off the pitch simultaneously and through a designated area.
In association football, players must wait until a stoppage in play to enter the pitch, and then only after the referee has been advised of the substitution. Although there are many variations, at the highest levels of competition, generally three substitutions are allowed per side during a match.
In football, the penalty kick is taken at a spot inside the center of the Penalty Area 12 yards from the goal, called the penalty mark.
In futsal, the first penalty mark is analogous to the penalty mark in football and is 6 metres from the midpoint of the goalposts.
Association football, more commonly known as simply football or soccer, is a team sport played with a spherical ball between two teams of 11 players. It is played by approximately 250 million players in over 200 countries and dependencies, making it the world's most popular sport. The game is played on a rectangular field called a pitch with a goal at each end. The object of the game is to score more goals than the opposition by moving the ball beyond the goal line into the opposing goal, usually within a time frame of 90 or more minutes.
Offside is one of the laws of association football, codified in Law 11 of the Laws of the Game. The law states that a player is in an offside position if any of their body parts, except the hands and arms, are in the opponents' half of the pitch, and closer to the opponents' goal line than both the ball and the second-last opponent.
Futsal is a football game played on a hard court, smaller than a football pitch, and mainly indoors. It has similarities to five-a-side football.
A penalty kick is a method of restarting play in association football, in which a player is allowed to take a single shot on the goal while it is defended only by the opposing team's goalkeeper. It is awarded when a offence punishable by a direct free kick is committed by a player in their own penalty area. The shot is taken from the penalty mark, which is 11 m from the goal line and centred between the touch lines.
In the sport of association football, the referee is the person responsible for interpreting and enforcing the Laws of the Game during a match. The referee is the final decision-making authority on all facts connected with play, and is the match official with the authority to start and stop play and impose disciplinary action against players and coaches during a match.
The Laws of the Game (LOTG) are the codified rules of association football. The laws mention the number of players a team should have, the game length, the size of the field and ball, the type and nature of fouls that referees may penalise, the offside law, and many other laws that define the sport. During a match, it is the task of the referee to interpret and enforce the Laws of the Game.
A corner kick is the method of restarting play in a game of association football when the ball goes out of play over the goal line, without a goal being scored and having last been touched by a member of the defending team. The kick is taken from the corner of the field of play nearest to where it went out.
In various sports, a professional foul is a deliberate act of foul play intended to bring about an advantage for the perpetrator's team. Professional fouls are usually committed to prevent an opponent from scoring.
A football pitch is the playing surface for the game of association football. Its dimensions and markings are defined by Law 1 of the Laws of the Game, "The Field of Play". The pitch is typically made of natural turf or artificial turf, although amateur and recreational teams often play on dirt fields. Artificial surfaces must be green in colour.
A goal kick, called a goalie kick in some regions, is a method of restarting play in a game of association football. Its procedure is dictated by Law 16 of the Laws of the Game.
A dropped-ball is a method of restarting play in a game of association football. It is used when play has been stopped due to reasons other than normal gameplay, fouls, or misconduct. The situations requiring a dropped-ball restart are outlined in Law 8 and Law 9 of the Laws of the Game; Law 8 also contains the dropped-ball procedure.
A kick-off is the method of starting and, in some cases, restarting play in a game of association football. The rules concerning the kick-off are part of Law 8 of the Laws of the Game.
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.
The ball in and out of play is the ninth law of the Laws of the Game of association football, and describes to the two basic states of play in the game.
In association football, an assistant referee is an official empowered with assisting the referee in enforcing the Laws of the Game during a match. Although assistants are not required under the Laws, at most organised levels of football the match officiating crew consists of the referee and at least two assistant referees. The responsibilities of the various assistant referees are listed in Law 6, "The Other Match Officials". In the current Laws the term "assistant referee" technically refers only to the two officials who generally patrol the touchlines, with the wider range of assistants to the referee given other titles.
Association football was first codified in 1863 in England, although games that involved the kicking of a ball were evident considerably earlier. A large number of football-related terms have since emerged to describe various aspects of the sport and its culture.
Comparison of association football (football/soccer) and rugby union (rugby/rugger) is possible because of the games' similarities and shared origins.
In games of association football teams compete to score the most goals during the match. A goal is scored when the ball passes completely over a goal line at either end of the field of play between two centrally positioned upright goal posts 24 feet (7.32 m) apart and underneath a horizontal crossbar at a height of 8 feet (2.44 m) — this frame is itself referred to as a goal. Each team aims to score at one end of the pitch, while preventing their opponents from scoring at the other. Nets are usually attached to the goal frame to catch goalscoring balls, but the ball is not required to touch the net.
The video assistant referee (VAR) is a match official in association football who reviews decisions made by the head referee with the use of video footage and headset for communication. This is specifically in order to minimize human errors causing substantial influence on match results.
A free kick is a method of restarting play in association football. It is awarded after an infringement of the laws by the opposing team.
