A goal worth one point is awarded to the offensive team each time the entire ball crosses their opponent’s goal area. There is no equivalent to a 3 point goal in basketball. All goals are worth just 1 point.
Occasionally, a shot attempt results in the goal keeper stopping the ball at or near the imaginary plane of the goal area. This can be a very challenging call to make and a special goal camera is used at major competitions.
