Field hockey is an outdoor game played by two opposing teams, they must
drive a round hockey ball by hitting it with a hockey stick towards the
rival team's shooting circle and then into the goal.
A game consists of 4 quarters of 17 minutes each, with an break of 2
minutes. The goalkeeper wears thick, yet lightweight pads and, while in
the shooting circle, is allowed to kick the ball or stop it with the
foot or the body. All other players, however, may stop the ball with the
stick only.
