­This is a relatively new and rapidly growing, indoor sport, dating back to the 1970's and may be considered as a kind of ice-free version of ice-hockey. It is played using composite sticks with a plastic vented blade and a 72 mm plastic ball with the aim to ­put the ball into the opponent's goal. A team consists of 5 players and a goalie (who plays without a stick) in a court 40 x 20 metres and enclosed by a board with rounded corners. Players must not use their hands, arms or head to play the ball on purpose. One may use other body parts ( the ball can be stopped by a foot, but not to score goals or pass to team mates).
