FUTEBOL DE SALAO: Over a century, ago fooball arrived in Brazil. But there weren't many good playing areas. So a new game developed - futebol de salao, played on a hard court with a small ball (actually it was a handball). The classic futebol de salao ball is a size two-and-a-half and weighs 465g - that's 20g heavier than the maximum weight allowed for a standard size 5 match ball. There isn't much bounce because the bladder (inside) is filled with dense foam that reduces rebound to a minimum FUTSAL: In 1989, FIFA standardised an international set of rules for the game known as futebol de salao and it became known as futsal. But some people still advocate the traditional version. A company in America - Select - was commissioned to produce an official futsal ball and came up with the 'Jinga' - a size four ball that weighs the same as a full size five. This company also designed a smaller size three ball for young children that weighs only 350g - the 'Junior Jinga' ball. BOTH VERSIONS HAVE SIMILAR RULES: ? A junior game lasts for 15 minutes, with a maximum half time break of 10 minutes. Adult games last 20 minutes. ? Each team consists of five players, including the goalkeeper. Seven substitutes are allowed on a rolling basis. ? All the players (goalkeeper included) are allowed anywhere on the pitch. Only the goalkeeper may handle the ball. ? The goalkeeper may only throw the ball to a player in his own half of the pitch. ? There is no height restriction for the ball in play. ? Use of the walls is not permitted. 'Kick-ins' and corners are awarded when the ball goes out of play. ? Fouls are penalised by the offending player being 'benched' for two minutes. ? Sliding tackles are not permitted. The ball must not be headed. ? Each team is allowed two time-outs (as in basketball) of one minute.
