Indoor soccer

Indoor soccer or arena soccer, or six-a-side football in the United Kingdom, is a game derived from association
football adapted for play in an indoor arena such as a turf-covered hockey arena or skating rink.
The most important difference in play is that the indoor field is surrounded by a wall instead of touch lines,
resembling more of a hockey rink than a soccer pitch. The ball can be played directly off the wall,
which eliminates many frequent stoppages that would normally result for throw-ins, goal kicks and corner kicks,
and generally results in a faster paced game. The term "indoor soccer" is so well-known as a description of the
different style of the game that it is even used to describe similar fields which are built outdoors.
