The game duration is shorter in 9-a-side regulations than in competitive football. There are two half, each lasting 30 minutes. A 20-minute half can be played under informal situations, but not less. A ten-minute half-time break is also provided. When playing in a league or tournament, the game lasts for 90 minutes plus extra time if needed. In test matches, games may last as long as 5 hours (3 periods of 45 minutes plus 2 additional 15-minute halves). In a 7-a-side match there are only seven players a side instead of nine. The extra player usually takes the place of the goalkeeper. Women's football is also growing in popularity and women's games often have a smaller number of players per team. Typically, a women's game will have between 11 and 13 players per side. This type of game can last up to an hour longer than a men's game due to the lower number of players involved. Kids' football is also popular and games involve between 6 and 18 year olds. These games are usually split into two separate halves with a 10-minute break in between. The age range depends on the rules set by organizations who organize youth tournaments and leagues. College football is also popular and the average length of a game is about 60 minutes.
