Normal Sudoku Rules Apply:
Each row, column and 3x3 box contains the digits 1-9.
Region Sum Lines:
Digits on a line have the same total for each separate instance within each region along the same line. Different lines may have different totals.
Doublers:
One cell in every row, column, and box is a Doubler cell, every digit from 1 to 9 must appear in a doubler cell exactly once. The value of a Doubler cell is equal to twice the digit it contains.
Partial example below.
In this example, the yellow cells have been deduced as the doublers.
23 = (2x7)+9 = 2+5+6+3+7
6 = 2x3 = 6 = (2x1)+4 = 6
Lösungscode: Digits from Row 6

Somebody clearly gave Flinty some tinder, because this puzzle they just gave us was pure fire.
Flinty: Thank you :)

Very nice flow with the doubler logic in this one!

Normally, I avoid puzzles with modifier cells. Just attempted this because I could see the start immediately. And it kept going, surprisingly well guided. Thank you!
Flinty: Thank you :) ... it's no Numbered Rooms or Renban though. ;) x

Doublers usually leave me pulling my hair out, but this had a very clear solve path. Not too easy, but a very logical set up.
