10 Basketball Rules !!install!! -

The rectangular court is bordered by lines. The ball and the player in possession must remain inside these lines. If a player steps on the line, or if the ball touches the line, it is considered "out of bounds," and possession is awarded to the opposing team. Conversely, a player can jump from inbounds, save the ball from going out, and pass it back in—as long as they are in the air and haven't touched the floor out of bounds.
