In 2018, the Wolfpack reached the Qualifiers, an end of season round robin tournament for the four top teams from the RFL Championship, and the bottom four teams from Super League. Finishing fourth qualified Wolfpack for the Million Pound Game, a final eliminator for the last place in Super League in 2019. However, they were defeated 6–4 by London Broncos, and thus rejoined the RFL Championship for the 2019 season. That season saw a change in the promotion system, with the top five Championship teams entering a playoff whose winner received automatic promotion to Super League. The Wolfpack finished atop the Championship regular-season table, and easily won both of their playoff matches, securing their promotion to Super League with a 24–6 win over Featherstone Rovers.
