Huddersfield, Catalan Dragons, Wigan, Warrington, Bradford and London Broncos all won in the Carnegie Challenge Cup fourth round on Sunday.
Super League leaders Huddersfield came from 14-0 down to sweep aside injury-hit Hull with a dominant second-half display and book their place in the fifth round of the Carnegie Challenge Cup.
The Giants' exciting outside backs did the damage, scoring six of their eight tries, the pick of them an 80-metre individual effort from Leroy Cudjoe that put them in front for the first time on 54 minutes.
Luke George, Greg Eden, Cudjoe again, Joe Wardle, Luke Robinson and Jason Chan also crossed in the second half as the Giants fought back from 4-0 down.
George had given them a foothold with the Giants' first points just before the break.
Tom Briscoe's try double had earlier put the hosts ahead.
In the other all-Super League tie of the day, two tries from Leon Pryce helped Catalan Dragons to a thrilling 20-18 win at Hull KR.
The Dragons, who led 20-0 at one stage, held off a stirring second-half comeback from the Robins, who actually outscored their opponents four tries to three only for three missed conversions by Michael Dobson to prove costly.
Pryce opening the scoring on seven minutes, doubled his tally on 34 and Ian Henderson's effort put the visitors 20 points up at the interval.
Tries from Scott Taylor, Blake Green, Josh Hodgson and Sam Latus brought the hosts right back into the game in the second half but Dobson's kicking - his last miss coming after Latus' 70th-minute try - meant they failed to progress.
Sam Tomkins scored six tries as Wigan kicked off their defence of the Challenge Cup in fine style, running in 18 tries in all to trounce the North Wales Crusaders 98-4.
Liam Farrell, back from injury, helped himself to a hat-trick, while debutant Ryan King also crossed, scoring the game's opening try.
Warrington also eased through with a clinical 44-18 defeat of Championship side Keighley.
Tony Smith's men ran in eight tries against their part-time opponents, with young hooker Brad Dwyer among the scorers.
Joel Monaghan, Ben Westwood, Chris Hill, Rhys Williams, Chris Riley, Ben Harrison and Paul Wood also crossed with Lee Briers slotting six conversions.
The Wolves were 22-0 ahead in as many minutes, dashing any hopes the Cougars might have had of repeating Featherstone's heroics against Castleford 24 hours earlier.
And though they were rarely at their sparkling best, Warrington still had far too much for Jason Demetriou's side.
Shaun Ainscough and Elliott Whitehead both bagged hat-tricks as cash-strapped Bradford strode effortlessly into round five with a 72-6 success over Doncaster.
The five-time cup winners, still striving to find £1million to stay in business, ran in a total of 13 tries with stand-in kicker Danny Addy adding 10 goals.
The Championship One front-runners did at least manage to open the scoring when Russ Spiers crashed over.
However, the lead lasted barely two minutes as Bradford took control and duly progressed to the last 16.
Michael Witt bagged a 22-point haul as the London Broncos cruised into the fifth round of the Challenge Cup by steamrollering part-timers Dewsbury 72-4.
Witt crossed for two tries and booted seven goals as the Londoners romped to a 13-try victory.
The Rams finally gave their travelling fans cause for cheer in the 62nd minute when Jamaine Akaidere crossed in the corner after a break from Matty Nicholson.
The other Super League side in action, Salford, ensured there would be no major upset to follow Saturday's win for Featherstone over Castleford as the City Reds won 58-18 at Whitehaven.
Salford scored 10 tries in all, Joel Moon and Marc Sneyd, who finished with 26 points, both bagging a brace.
Loan signing Ryan Brierley scored four tries to help Leigh to a crushing 68-18 win over Rochdale Hornets.
The Centurions, Cup winners at Wembley in 1971, established a 26-12 half-time lead at Leigh Sports Village, where Brierley, who is on loan from Castleford, provided the second-half highlight with a hat-trick.
Another Wembley winner, Sheffield Eagles, ran in nine tries in a 50-12 rout of York at the Huntington Stadium.
Nev Morrison and Quentin Laulu-Togagae both scored two tries as the Eagles built on an 18-0 half-time advantage.
John Kear, a Cup winner with Sheffield and Hull, saw his Batley side hang on for a 21-18 victory at Hunslet.
Tries from Gareth Potts, Gareth Moore, Alex Walmsley and Ian Preece put Kear's men into a 20-10 lead early in the second half, but Andrew Yates and David March both scored their second tries of the match to set up a tense finish.
With both teams scoring four tries, Moore's two goals to one from the Hawks' Luke Helliwell proved the difference while the Batley half-back also put over a 78th-minute drop goal.
Finally Oldham overturned a 14-6 half-time deficit to score 20 unanswered points after the break and run out 26-14 winners over Barrow to book their place in Monday's fifth-round draw.
