Rules
- Sudoku: Normal sudoku rules apply.
- Doublers: Nine cells (one per row/column/box) are doublers, and have values equal to double their digit. Each digit appears in exactly one doubler.
- Nabner lines: On each line, the values of any two cells on that line must differ by at least 2.
Solve in Sudokupad or f-puzzles.
On a side note, I have a Patreon page as well, if you are interested in supporting my puzzle-making there. I also post patron-exclusive puzzles of various genres there each month.
Solution code: Row 5

How does one even construct a puzzle like this. This is so cool.
The doubler property is used in so many ways.

Incredibly smart puzzle. After working through it, I still have trouble fully grasping that this solved. That break in was a journey.

Incredible puzzle. I found it very nice and also very hard. In the end it almost made me feel sad to be finished, because of the challenge and joy it gave me. Thank you

Another masterpiece with logical clarity and challenging deductions. A joy to solve, even though I wondered several times how a solution could exist.
