Twelve teams take part in the tournament. They are split into four pools (labelled A-D) of three according to their past performance. Each team plays three matches against three teams of other pool (pool A plays against pool D and pool B plays against pool C). Four points are awarded for a win, two for a draw, and none for a loss. One bonus point is awarded for scoring 4 tries or more, and one bonus points is awarded for loss by 7 points or less.
After all pool matches teams are ranked by total match points. Top four teams qualify for the semifinals (1st against 4th and 2nd against 3rd). Likewise, other teams enter play-offs for positions 5-8 and 9-12.
