The regular season began play on 12 September 2009 and concluded on 2 March 2010,[1] with Vålerenga claiming their twenty-seventh League Championship after defeating Lillehammer 2–1 on 26 February.

[5] In June 2009, the Norwegian Ice Hockey Association (NIHF) denied Comet entry into the league for the 2009–10 season due to the club's poor financial situation.

[7] Less than two months later and shortly before the start of the season, the tax authorities in Halden successfully filed a bankruptcy claim against the club, the result being that they went into administration on 4 September.

[11] A last-ditch attempt by a group of local investors to save the club could not remedy the fact that Halden Ishall remained unavailable, and Comet folded on 6 October.

All results involving Comet were annulled and a sixth round robin was introduced, bringing the total number of games per team up to 48.

On 25 November, the Storhamar Dragons were found to have used an ineligible player during three games played that month, and were consequently handed a fine of 4,500 kroner.

This was the second time the two teams had met in a final, the first being in 2006 when Vålerenga won their twenty-fourth Norwegian Championship, sweeping the Oilers 4–0 in the best-of-seven series.

On this occasion, however, the Oilers defeated Vålerenga 4–2 to claim their first ever title, in the process also becoming the first club outside the traditional hockey powerhouse of Eastern Norway to win the championship.

With the score eventually tied at 4–4, the game went into overtime and was decided when Vålerenga and Mathias Trygg got the upper hand in a power play.

[27] Yet again, there were allegations of foul play, this time coming from Vålerenga, as Christian Dahl Andersen had scored the equalizer with his skate.

The result put the Oilers ahead 3–2 in the series, setting the stage for a possible championship deciding win at home in Stavanger.
