For the 2021 season, teams are separated into two groups and play each other twice (a double round-robin system) for six games, in which three points are awarded for a win, one for a draw and zero for a loss.

The top two of each group advance to a single-elimination knockout phase, with the winners progressing to the Grand Final and the two defeated teams contesting a third-placed play-off.
