The Six Nations is played in a round-robin format, with each team playing each other once.
That means, with six teams in the tournament, each nation plays five matches.
Home advantage will alternate each season. So, if England play Ireland at home one year, 12 months later they will visit them.
Teams receive four points for a win, two points for a draw, and zero points for a loss.
But there are also opportunities for teams to secure bonus points.
The team that secures the highest number of points from their five games wins the Six Nations.
