The International Paralympic Committee differentiates between five-a-side and blind football in 3 classes - B1 , B2 and B3 . In each game two teams with 4 field players each, a goalkeeper and five substitutes play. Field players must be blind or have a visual impairment. All players wear a blindfold to ensure equal opportunities. The goalkeeper is allowed to see and does not wear a blindfold. Behind the opposing goal each team has a teammate who shouts to help them aim. The ball makes noises when it moves in order to better determine its position. Two halves of 25 minutes each are played. In the event of a tie, a penalty shoot-out follows.
qualification
Eight men's teams competed in the qualifying games, which were held by the International Blind Sports Federation (IBSA), and were divided into 2 groups. Women's teams did not participate.
Each participating nation was allowed to send a team that consisted of eight field players and two goalkeepers - the goalkeepers do not count towards the permitted number of 64 athletes. However, like other non-disabled helpers, they can win medals.
