Hull secured back-to-back promotions despite being held by stubborn Swindon at the KC Stadium.
Peter Taylor's side wasted several good chances to win the match and striker Craig Fagan saw his last-minute penalty saved by Rhys Evans.
They also dominated the first half with Junior Lewis and Andy Dawson both spurning great opportunities to score.
But it mattered little when Tranmere only drew with Blackpool, booking Hull's passage to the Championship.
