Exploded Compass Sudoku

Every row, column and irregular region must contain the digits from 0 to 8. If there is an arrow in a cell, the digit in that cell equals the total number of cells belonging to the region the arrow comes from that are in the direction of the arrow. For instance, if r1c2 was 5, as it contains an arrow pointing to the left, this would mean that the region containing r1c3 would have 5 cells that are to the left of r1c3. All the possible arrows are given. Enjoy! |

Lösungscode: Column 5, column 6

Here is a sudokupad link to the puzzle because the original link doesn't work anymore: https://sudokupad.app/b7uvgrsfup
Very hard puzzle, anyway, I think it's not easier than the other puzzles in the series, but lovely logic. Had to use a lot of techniques to unfold the regions construction this time. Wild use of the negative constraint.

Thanks!
I'm curious, do you know why there is a sudden interest for this old puzzle?

Just some enthusiast solvers solving together your very nice puzzles :D I'm on a quest to complete all your compasses, very few remaining.

I at several points felt quite uncertain about my deductions, but I came stumbling through in the end! Very nice, but not particularly easy!

The entry was not easy to find (specifically, not the first but the second step of it, making the first step seem like a red herring initially) - but after that I more or less guessed my way to the solution at some speed (without even needing the negative constraint), for the long strings of arrows are a bit conspicuous...
