The term street football encompasses a number of informal varieties of association football. These informal games do not necessarily follow the requirements of a formal game of football, such as a large field, field markings, goal apparatus and corner flags, eleven players per team, or match officials (referee and assistant referees).
Often the most basic of set-ups will involve just a ball with a wall or fence used as a goal, or items such as clothing being used for goalposts (hence the phrase "jumpers for goalposts"). The ease of playing these informal games explains why they are popular all over the world.
Street football can be divided into three varieties: minor adaptations of the association football rules, games based on scoring goals and games which are not.
In 2005, video game publisher Electronic Arts introduced FIFA Street, a franchise based on street football and freestyle football. FIFA Street series focuses on flair, style and trickery, reflecting the cultures of street football and freestyle football played in streets and backlots across the world. There have also been several online flash games based on street football.
