Exploded Compass Sudoku

(Published on 7. January 2021, 20:00 by stephane.bura)

Every row, column and irregular region must contain the digits from 0 to 8.
You must draw the nine contiguous regions.

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, r1c8 is 5 and contains an arrow pointing to the left. This means that the region containing r1c9 has 5 cells that are to the left of r1c9.

Enjoy!

Another great entry in the series! I found it a lot more challenging than the others, broke it multiple times. But I think allowing arrows in every cell adds some interesting layers of logic.

What a great drama! I thought for a good 15 minutes that I had broken the puzzle, before I finally noticed the only working option. Phew! Fantastic puzzle - very challenging but also rewarding.

Brutal. Couldn't find an elegant path and had to go through a lot of try and error.

Suberb! Probably the best (and hardest) of the series. Very interesting and challenging throughout.
