#6 Field Hockey

The FIH is also responsible for organising the Hockey Rules Board and developing the rules for the game. A popular variant of field hockey is indoor field hockey, which differs in a number of respects while embodying the primary principles of hockey. Indoor hockey is a 5-a-side variant, with a field which is reduced to approximately 40 m × 20 m (131 ft × 66 ft). With many of the rules remaining the same, including obstruction and feet, there are several key variations: Players may not raise the ball unless shooting on goal, players may not hit the ball (instead using pushes to transfer the ball), and the sidelines are replaced with solid barriers which the ball will rebound off.
