<P> Played annually, the format of the Championship is simple: each team plays every other team once (making a total of 15 matches), with home ground advantage alternating from one year to the next . Prior to the 2017 tournament, two points were awarded for a win, one for a draw and none for a loss . Unlike many other rugby union competitions the bonus point system has not previously been used . </P> <P> On 30 November 2016, the 6 Nations Committee announced that the bonus point system will be trialled for the 2017 Championship . The system is similar to the one used in most rugby championships (0 points for a loss, 2 for a draw, 4 for a win, 1 for scoring four or more tries in match, and 1 for losing by 7 points or fewer), with the only difference being that a Grand Slam winner will be given 3 extra points to ensure they finish top of the table . </P> <P> Prior to 1994, teams equal on match points shared the championship . Since then, ties have been broken by considering the points difference of the teams . The rules of the championship further provide that if teams tie on both match points and points difference, the team that scored the most tries wins the championship . Were this decider to be a tie, the tying teams would share the championship . To date, however, match points and points difference have been sufficient to decide the championship . </P> <P> Also, the team that finishes at the bottom of the league table is said to have "won" the Wooden Spoon, although no actual trophy is given to the team . A team that has lost all five matches is said to have been whitewashed . Since the inaugural Six Nations tournament in 2000, only England and Ireland have avoided the Wooden Spoon award . Italy are the holders of the most Wooden Spoon awards in the Six Nations era with eleven, and have been whitewashed six times . However, each of the other five nations has accumulated more than that through competing in previous eras . </P>
