The sixteen teams were split into four groups - A, B, C & D, based on geographical location. Each team in the group played each other once, to the 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 each group, the winner and runner up in each group progressed to the Final Stage. In the final, the 8 teams (4 Winners and 4 Runners up) were arranged into 4 quarter-final pairings. The winners of each match qualified for the Cup semi-finals, with the losers moving into a new Plate competition. Thereafter, competition was a simple knockout bracket, with the winner of the Cup final being declared the series winner.
