Indoor soccer

Indoor soccer or arena soccer (known internationally either as minifootball, fast football, floorball, showball) is a game derived from association football adapted for play in a walled indoor arena. Indoor soccer, as it is most often known in the United States and Canada, was originally developed in these two countries as a way to play football during the winter months, when snow would make outdoor play difficult. In those countries, areas such as ice hockey courts or skating rinks are adapted for indoor soccer play. In other countries the game is played in either indoor or outdoor arenas surrounded by walls, and is referred to by different names (such as fast football (futbol rapido) in Mexico, showbol in South America, and indoor football (futbol indoor) in Spain).

Indoor soccer has different regulations from other versions of association football designed for indoor play, such as futsal and five-a-side football. Unlike futsal, which is played on ceramic surfaces, indoor soccer is played on synthetic turf. Indoor soccer courts are delimited by walls instead of lines, and there are no player throw-ins.
