The twelve teams were split into four groups – A, B, C & D. Each team in the group played each other once, to World Rugby Laws of the Game – 7s Variations.
Based on the result, teams received:
4 points for a win
2 points for a draw
1 bonus point for a loss by seven points or less
1 bonus point for scoring four or more tries in a match
Following all matches in each group, the winner and runner-up in each group progressed to the quarter-finals and the third-placed team progressed to the bowl semi-final. The winners of each quarter-final qualified for the cup semi-finals, with the losers moving into a new plate tournament. Thereafter, competition was a simple knockout bracket, with the winner of the cup final being declared the series winner.
