round-robin tournaments. In The Qualifiers, the top three sides will either remain in or be promoted to Super League, with the fourth- and fifth-place teams playing the aforementioned "Million Pound Game" for the final Super League place. In the third league, the sides compete for the Championship Shield, with the top four teams after the round-robin phase entering a knockout playoff for the Shield. The bottom two teams are relegated to League 1. League 1 currently conducts a 15-match, single round-robin regular season. At that time, the league splits in two. The top eight clubs play in their own Super 8s, also contested as a single round robin. At the end of the Super 8s, the top club earns the season title and immediate promotion to the Championship. The second- through fifth-place clubs contest a knockout playoff for the second place in the Championship. The bottom eight clubs play their own single round-robin phase; at its end, the top two teams play a one-off match for the League 1 Shield.

A relegation play-off involving the bottom four teams existed through the 2011–12 season, but was scrapped from 2012 to 2013 on. The original promotion play-offs divided the eight teams into two groups of four each, with the teams within each group playing a home-and-away mini-league. The top two teams in each group advanced to a knockout phase. In 2010, the semi-finals were one-off matches; in 2011, they became two-legged.
