20x20 Standard Yajilin
(Published on 14. June 2021, 14:11 by stefliew)
Normal Yajilin rules apply:
Blacken some white cells so that no two blackened cells are orthogonally adjacent and draw a single non-intersecting loop through the remaining white cells that goes horizontally and vertically, from cell center to cell center.
Clues represent the number of blackened cells in a straight line in the indicated direction. Not all blackened cells need to be pointed at by a clue.
Trial and error is not required!
Solve on Penpa+
Solution code: Number of blackened cells in rows 4, 7, 10, 13, 16, 19 and columns 2, 5, 8, 11, 14, 17 (12 digits).

The Penpa+ link is currently not working - I made one using tinyurl instead.
Edit: Stef posted a new one, now with answer check!

The current rating totally belies the true beauty and elegance of this puzzle. Such an incredible shame! I can only assume that the intended path wasn't found, because it is just so breathtaking & clever. For any future solvers, there is no T&E needed, nor any complicated (break-in aside) / messy steps at all. Thank you so much stefliew :)

Removed puzz.link link to encourage people to use penpa or actual pen and paper for this puzzle instead

I asked me, how to construct such a monster. Solve it and you can read the answer ;-)
Thank you for the explanation.
