Rugby league football, usually called rugby league, is a full played by two teams of thirteen players on a rectangular grass. In rugby league points are scored by carrying or kicking the ball down the field, until it can be moved past the opponents’ designated goal line and touched to the ground; this is called a “try”, and is the primary method of scoring.
The opposing team attempts to stop the attacking side gaining points by preventing their progress up the field by tackling the player carrying the ball. In addition to tries, points can be scored by kicking goals. After each try, the scoring team gains a free kick to try at goal with a conversion for further points. Kicks at goal may also be awarded for penalties, and field goals can be attempted at any time during general play.
