Score a "try" in the in-goal area or kick the ball through the uprights for points.
Rugby is often described as a mix between football and soccer. Teams score by touching the ball to the ground at the end of the field for a “try” (five points), or by kicking the ball through a large set of posts at the end of the field (three points during play, or two points after a try). Hands and feet can both be used, but passing the ball forward is a no-no. Play doesn't stop when the ball carrier is tackled, it's an immediate fight for possession of the ball. Then there's the scrum, which is like a big, post-penalty hug.
