How do you score in rugby union?

• The values: "Try. Five points." "Conversion. Two points." "Penalty try. Seven points." "Penalty goal. Three points." "Dropped goal. Three points."
• A try: an attacking player "is first to ground the ball in the opponents' in-goal".
• Also a try: when a scrum, ruck or maul reaches the try line and an attacker grounds the ball first.
• Sliding in or reaching out: a tackled player whose momentum carries them into in-goal, or who immediately reaches out, may score.
• The conversion: "may be a place-kick or drop-kick", in line with where the try was awarded.
• 60 seconds: from the time the try was awarded. Otherwise the kick is disallowed.
• The defenders: retire to their try line and may charge once the kicker begins the approach to kick.
• A goal: the ball must go over the crossbar and between the posts without first touching a team-mate or the ground.
• Penalty goal: the team must say it is kicking at goal, then kick within 60 seconds. Defenders stand still with their hands by their sides.
• Dropped goal: kicked from a drop kick in open play.
• Penalty try: awarded between the posts when foul play prevents a probable try. The offender is shown a yellow or red card.
• Declining: a team may decline the conversion by saying "no kick".

The glossary has the try, the conversion, the penalty goal, the dropped goal, the penalty try and the goalposts.

A try is worth more than any kick, so teams are rewarded for crossing the line rather than settling for three points. The conversion is taken in line with where the try was scored, which makes the attacker run towards the posts. Letting defenders charge keeps the conversion a contest.
