Some Self-Referential Arrows Somedoku
This is somedoku #21. Check out the rest of the puzzles in the somedoku series.
Rules:
- Somedoku: Fill each cell with a digit from 1-9. Fill every row 'n' and column 'n' with exactly 'n' different digits, repeating digits as necessary.
- Self-Referential Arrows: The digit in a cell with an arrow tells you how many steps along that arrows path until that digit sees itself for the first time. e.g. if R2C3 was a 2 then R4C3 must be a 2 and R3C3 must not be a 2.
- ?: A cell with a "?" must have at least one valid arrow. This arrow may be diagonal.
- Palindrome: Digits along a gray line must read the same forward and backward.
Solution code: Column 8 from top to bottom

Each deduction is so clear once found yet so carefully hidden, amazing somedoku!

It's been a while since I last solved a Somedoku, and what a lovely way to be reintroduced! Really beautiful structural logic, with terribly satisfying resolutions towards the end!
