In all, four-ton finishes littered a breathtaking display as the 17-year-old averaged 105.11 and swept up the last eight legs.
He also notched maximums in the first eight legs, even getting eight shots into a nine-darter in just the second leg.
It meant Littler mocked murmurings over early exits in recent major events as he conjured one of the darts’ best performances of the year.
Fans loved it as the Warrington whizkid never let up – signing off with a century checkout.
One viewer posted: “Unplayable. Simply unplayable.”
Another pointed out: “105 isn’t even an insane average, it looked much better than that.”
And a third claimed: “May as well just hand the trophy to him now!”
Littler now faces Gary Anderson or Gian van Veen in Sunday’s semi-finals.
