Adelaide has leapfrogged Perth into third on the NBL ladder and exacted savage revenge for Friday night's lopsided shocker by belting the Wildcats 94-82.
A dominant 31-17 opening term on Sunday laid the foundation for the Sixers to produce a stunning 33-point turnaround following a hot-tempered, 21-point belting at Perth Arena two days earlier.
One of 10 players reported in the fourth quarter on Friday, Mitch Creek was outstanding at Titanium Security Arena, with 21 points and 10 rebounds, spearheading the 36ers' assault early with 15 first-quarter points at 100 per cent.
Daniel Johnson (18 points) and Nathan Sobey (17) also played pivotal roles, while Bryce Cotton led Perth's scorers with 14 points.
However, his tally came at just 27 per cent as the Sixers' scheming defence strangled the Wildcats into shooting just 33 per cent from the floor.
With Creek and Josh Childress at the forefront, Adelaide finish the opening term with a 14-2 flurry to motor ahead by 14 points at the first break.
Tempers threatened to boil over late in the quarter but the Sixers were unruffled, extending their advantage to 55-33 at halftime on Sobey's acrobatic slam.
Below his best on Friday, Daniel Johnson proved a match-up nightmare with 13 third-quarter points as the 36ers' buffer at one stage blew out to 65-37.
Still going strong and up 79-56 at three-quarter time, Adelaide took their foot right off the gas in the fourth to coast home, avoiding a third successive defeat and keeping their top-two aspirations alive.
Adelaide coach Joey Wright was rapt with his side's smart response to Friday's defeat.
"We stood up and played basketball without being silly," he said.
"It was a great defensive effort by us."
Perth coach Trevor Gleeson acknowledged the Sixers had worked harder from the outset.
"It was disappointing that we didn't work as hard as they did and they got the results on the board," he said.
