There are 4 main ways to score in rugby union. ‘Grounding’ the rugby ball in the other teams try-line scores you 5 points. After that, teams have a chance to kick the ball into the goal for an additional 2 points.
Drop goals award teams 3 points. Penalties awarded because of foul play result in a kick at goal for 3 points. This is one of the more common ways of scoring at the elite level.
