A futsal ball is a size below a normal football, while it also has 30 per cent less bounce.
- Games are formed of two 20-minute halves, with time stopping at every dead ball.
- Each team is allowed to use one timeout each period, which last one minute.
- Each side begins with five players on the pitch, with one as a goalkeeper.
- A maximum of 12 players per team can be used, with substitutions unlimited and does not require a stoppage.
- Direct free kicks are counted as accumulated fouls, with teams warned by the referee when they reach five per half.
- Yellow and red cards are still handed out, just like in the grass version.
- Futsal has two penalty spots, one at 10 metres and the other in the goalkeeper’s area at 6m.
- A kick from the 10m spot is awarded when a team commits six or more accumulated fouls. All opponents must be behind the ball, while the goalkeeper has to be at least 5m away.
- A penalty kick from the 6m spot is taken when a player is fouled in the goalkeeper’s area.
- When a goalkeeper has the ball, he must get rid of it within four seconds, or concede an indirect free-kick.
- Once the goalkeeper has released the ball, it needs to go out of play or be touched by an opponent before he can receive it once again.
- Goalkeeper can play as normal in the opponent’s half.
- Instead of the normal throw-in in regular football, futsal has a kick-in.
- In all matches, one referee is positioned near the timekeeper table and another is on the opposite side.
- For international games, there is a timekeeper and a third referee that controls the team benches.
Junior leagues and shorter matches may adapt the foul count and tweak other laws to suit teams and conditions
