Each team consists of five players, including the goalkeeper and an unlimited number of substitutions, from a selection of three to five players. Throw-ins and kick-ins mean the pace and flow of the game are much faster than regular football. Shoes are not allowed; players must play in bare feet, although ankle guards are permitted. A game lasts thirty-six minutes, and is split up into three twelve-minute periods. Draws are not permitted, with the game going into three minutes of extra time, followed by a penalty shootout if the score is still on level terms after normal time. Unlike football, penalty kicks are decided by sudden death rules.
