Table ranking rules Four match points are awarded for a win. Two match points are awarded for a draw. A bonus match point is awarded to a team that scores four or more tries in a match or loses a match by seven points or fewer. If a team scores four tries in a match and loses by seven points or fewer, they are awarded both bonus points. Three bonus match points are awarded to a team that wins all five of their matches (known as a Grand Slam). This ensures that a Grand Slam winning team always ranks over a team who won four matches in which they also were awarded four try bonus points and were also awarded two bonus points in the match that they lost. Tie-breakers If two or more teams are tied on match points, the team with the better points difference (points scored less points conceded) is ranked higher. If the above tie-breaker fails to separate tied teams, the team that scored the higher number of total tries in their matches is ranked higher. If two or more teams remain tied for first place at the end of the championship after applying the above tiebreakers, the title is shared between them.
