Two-goal hero Owen Sidney struck on 40 and 49 minutes to earn Henllan maximum points at Maesdu Park.
Aflie Jones had given Llandudno a second-minute lead before the visitors turned the tables through 17-year-old dazzler Sidney.
Harry Benjamin netted twice for a second-place Phoenix side who closed the gap on leaders Mochdre Sports Development to three points.
It was 1-0 at half time, Benjamin on target, before the striker completed his double in the second period with Billy Seiben and sub Ben Hughes also hitting the net.
Jake Carey’s second goal of the afternoon on 77 minutes clinched the win for Conwy.
Carey notched the only net-finder of the first half on 28 minutes before a Dylan Jones penalty and Jamie Williams strike, both after 57, turned the game around in Wanderers’ favour.
However, Romanian sub Denis Craciun levelled on 59 before Carey delivered the decider for the fourth-placed Swifts.
A 92nd minute winner from sub Harrison Northall secured a 4-3 victory in Saints favour at Roe Plas Meadows.
Joshua Guelbi gave Asaph a second-minute lead, before a Leon Melling pair on five and 11 edged Bridge to the front.
It stayed at 2-1 to the visitors before Macauley Lewis equalised for Saints on 63.
Sub Connor Thomas restored the home lead after 81, but Melling’s hat-trick goal on 88 looked to have sealed an away point.
However, Jack Davies provided the assist for Northall to supply the all-important fourth home goal two minutes into added time.
Six straight wins and nine without defeat for Pwllheli, who are up to second in the standings.
In the only West game to survive the weather, Steffan Toplis gave the hosts a 42nd minute lead, but Connor Livingstone’s own goal after 45 made it all-square.
Harri Grant put Pwll 2-1 up after 49 and the win was sealed when sub Iwan Roberts-Jones scored on 91 from a Cai Rhys Jones assist.
