<P> Following the relative success of the Tier 2 nations in the 2015 Rugby World Cup, there were calls by Octavian Morariu, the president of Rugby Union's governing body for promotion and development, to let Georgia and Romania join the Six Nations due to their consistent success in the European Nations Cup and ability to compete in the Rugby World Cup . </P> <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>
