Throw-ins are used to get the ball back in play after it gone out of play by crossing a side touch line. The basic rules for a proper throw-in are:

At the moment of delivering the ball, the thrower:

• faces the field of play
• has part of each foot either on the touch line or on the ground outside the touch line
• uses both hands
• delivers the ball from behind and over his head
• The thrower may not touch the ball again until it has touched another player.

If the player performs a throw-in incorrectly, the possesion of the ball switches to the opposing team. In the younger age groups the referee may allow the player to repeat and incorrectly made throw-in.
