Eliteserien play-offs

Play-offs were introduced in the 1972, when the 1. divisjon was expanded from ten to twelve teams. The 2. divisjon consisted of two conferences, and the winners of each conference were promoted directly. The runners-up met the winner of a conference from Northern Norway, with the three teams playing a single round-robin to determine the third and final promotion spot. Three teams were relegated from the 1. divisjon. This system remained for seven years, before the separate conferences for Northern Norway were abolished. From 1979 the play-offs were played as a two-tier match between the two conference runners-up, a system which was used for two seasons.

From 1981 the system returned to a three-team single round robin, although this time the two 2. divisjon runners-up met the team finishing tenth in the 1. divisjon. The format remained for thirteen years, with six top level teams succeeding in retaining their place. No play-off was played in 1994, as the top flight was increased to fourteen teams and both the winners and runners-up of both 1. divisjon conferences were promoted, while only two top flight teams were relegated.

From 1995 the play-off solely involved a two-tier match between the runners-up of the 1. divisjon conferences, with three teams from the top flight meeting relegation. This system remained for two years, before 1997, when the 1. divisjon was merged to a single conference. For twelve years the play-off was played as a two-tier game between the team finishing twelfth in the top flight and the team finishing third in the 1. divisjon. In this period the top level teams defended their positions nine times, including every year from 2001 through 2006.

From 2009 the play-off has been played as a knock-out tournament. The first two years saw the teams ranked three through five in the 1. divisjon meet the team ranked twelfth in the top flight in a two-round knock-out, with a single match in the first round and double match in the second round. In 2009 the top flight was extended to sixteen teams: three teams were promoted and only one relegated. In 2011, no play-off was carried out. From 2012 the play-offs returned as a three-round knock-out tournament. The teams ranked three to six in the 1. divisjon played each other in a two-round, single-match knock-out tournament, with the winner facing the fourteenth-placed top flight team in a two-legged decisive final.
