Comparison of Canadian football and rugby union by kicking the ball between the posts and over the bar. In Canadian football this is called an extra point (worth 1 point); in rugby union it is known as a conversion (worth 2 points). (The result is that both the touchdown/extra point combination and the try/conversion combination, when successful, total to 7 points.) One key difference between an extra point and a conversion is that a conversion kick must be taken from a position in line with where the try was scored, although the distance from the try line from which the conversion kick is taken is not fixed.
Rugby union gameplay carrying the ball can be tackled and once a tackle is completed the opposition can compete for the ball. Play continues until a try is scored, the ball crosses the side line or dead-ball line, or an infringement occurs. After a team scores points, the non-scoring team restarts the game at the halfway with a drop kick towards the opposition. The team with the most points at the end wins the game. A typical passage of rugby union takes the following form. Unlike rugby league and gridiron football, possession of the ball in rugby union is contestable at any time
