Each team plays the other five once per season with home advantage in alternate seasons and a total of 15 matches per Championship.
The RBS 6 Nations Championship Trophy is presented to the team which scores the most points during the competition, with 2 points being awarded for a win, and 1 point for a drawn match.
If two or more teams finish the Championship with the same number points, the winner is decided on match-points difference (subtracting match-points 'against' from match-points 'for' in all Championship matches). If there is still no winner, then it is awarded to the team who scored the most tries during the Championship.
If a winner still cannot be decided then the Championship is shared between the teams.If a team also wins all of their five matches, they are given the title of Grand Slam winner
