Rugby Union is a sport that is played by two teams of 15 players. The aim of the game is to score more points than your opponent by carrying, kicking, or passing a round ball called an oval (rugby ball) over the other teams goal line. The team that crosses the line with the ball scores a 'try' and then gets a chance to kick the ball over the goal posts and score extra points, called a 'conversion'. The team that scores the most points at the end wins!
