2. Each team plays the other five once per season with home advantage in alternate seasons (eg England hosted France in 2003, and so France host England in 2004), giving a total of 15 matches per Championship.
3. The RBS 6 Nations Championship Trophy is presented to the team who earn the most points during the season, 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 after all this a winner still cannot be decided then the Championship is shared between the teams.
4. If in winning the Championship a team also wins all of their five matches, they are given the title of 'Grand Slam' winner.
