Format
The Hong Kong Sevens is the sport's most prestigious annual rugby sevens event organised by the IRB Sevens World Series, Historically, it had been contested by 24 teams; all other World Series tournaments had 16 teams participating until the 2012–13 edition. The teams are divided into six pools of four teams, who play a round-robin within the pool. The winning team of the tournament acquires 30 points towards its rankings in the World Series instead of the normal 22, and the runner-up earns 25 points instead of the normal 19. Through the 2008–09 IRB Sevens season, the Hong Kong Sevens awarded 24 points to the runner-up, and 16-team events offered only 20 points for the winner and 16 for the runner-up.)
The 2010 edition saw several significant changes to the tournament format. Foremost among these changes was the introduction of the fourth-level Shield trophy, which had not previously been awarded in Hong Kong. More important within the context of the IRB Sevens as a whole, the Cup and Plate are now contested in the same manner as in other competitions, with the losing quarter-finalists in the Cup parachuting into the Plate semifinals.
Further major changes were made to the event for 2013. These changes resulted from the IRB's decision to institute a formal promotion and relegation process for core teams (i.e., teams assured of playing in all series events) starting with the 2012–13 series.
For starters, the number of teams involved in the event will increase from 24 to 28. However, only 16 of these teams will compete for series points. The 15 core teams will he joined in the main draw by the winner of the most recent edition of the HSBC Asian Sevens Series. The remaining 12 teams, specifically two qualifiers from each of the IRB's six regional zones, participate in the World Series Pre-Qualifier. Like the main draw, the Pre-Qualifier groups the entrants into four-team pools. The top two teams from each pool, plus the top two third-place teams, advance to a quarterfinal round, with the winners of all four matches, along with the Asian Sevens Series winner, advancing to the World Series Core Team Qualifier at the London Sevens.
The total prize money stands at US$150,000. The Cup Champion wins US$100,000, and the runner-up takes home US$25,000; each semi-finalist loser receives US$12,500.
