A 75th-minute strike from substitute Tom Barkhuizen earned Blackpool a 1-0 home win over relegated Reading, who suffered their first loss since returning to the division.
QPR, who came down alongside Reading, were 1-0 victors in the day's early game at Bolton thanks to a 54th-minute goal from striker Andrew Johnson.
Leicester also picked up a third win from four games but needed to come from a goal down before beating Birmingham 3-2 at the King Power Stadium.
The visitors took a 12th-minute lead through Matt Green but Nigel Pearson's men hit back with three goals in the final 12 minutes from Jamie Vardy, Andy King and David Nugent (penalty) to clinch the points before Birmingham struck again late on through Chris Burke.
The three leaders are a point clear of Nottingham Forest, who will look to continue the division's only 100 per cent record when they go to Watford on Sunday.
Leeds are on eight points after they too recovered from an early deficit to defeat Ipswich 2-1, goals from Luke Varney (28) and Ross McCormack (49) cancelling out David McGoldrick's 12th-minute opener for the hosts.
Summer signing James Vaughan scored a hat-trick as Huddersfield cruised to a 5-1 home win over promoted Bournemouth.
The Everton product netted in the 27th, 42nd and 58th minutes with Adam Hammill (14) and Adam Clayton (78) also on the scoresheet as Huddersfield's upward progress continued. Bournemouth's sole response was from Marc Pugh in the 68th minute.
Barnsley scored first and last at Blackburn as they sought their first win of the season but ended up on the wrong end of a 5-2 scoreline.
