Both blind and partially sighted football is 5-a-side with four outfield players and a goalkeeper.
In partially sighted matches, all five players on the team have a visual impairment whereas in blind football the goalkeepers are sighted but cannot leave their areas. They can also only direct the players on their team when the ball is in their defensive third. A guide behind the goal each team is attacking can then direct players when the ball is in the attacking third.
Partially sighted football is played on indoor futsal pitches and throw-ins are taken as in FIFA matches.
Blind football is slightly different, 1.2 metre high walls run along the sides of the pitch to allow the game to flow.
There are also two penalty spots, with the one further out being used when a team commits four fouls during a game.
Partially sighted football uses a size 4 ball that is designed to bounce less than a normal ball.
In blind football, ball bearings are placed inside the football so that a rattle is made when the ball moves and players know where it is.
Matches are 25 minutes each half. If it’s a draw at full-time in a knock-out game then the game goes straight to a penalty shootout.
Similar to a basketball shot clock, once the goalkeeper has released the ball, the team has 15 seconds to cross the halfway line with it otherwise they lose possession. The keeper cannot throw the ball past the halfway line.
