Never (Yajilin/Sudoku) by Wessel Strijkstra
-
Apparently, the unicode arrows in the f-puzzles and sudokupad links don't show up on some devices. To my knowledge, the penpa link should display everything properly.
Rules:
- Normal sudoku rules apply.
- Grey cells are yajilin clues. The direction of some clues has been given, the direction of some clues and the values of all clues have to be determined.
- Yajilin rules: shade some cells so that no two shaded cells are orthogonally adjacent and draw a non-intersecting loop through the centers of all the remaining empty cells. Clues cannot be shaded, and represent the number of shaded cells in a straight line in the indicated direction.
- A clue outside a row gives the sum of the digits on the first horizontal segment passing through its row (including the cells which it turns), likewise for columns and vertical segments.
Enjoy!
Solution code: Digits in r5, followed by digits in c6. Left to right, top to bottom.

One of the best puzzles I solved in awhile. Thank you!

The rules don’t say that the loop must pass through orthogonally connected cells only. Had to look that up on Wikipedia first and then I could make progress. A thrilling puzzle thanks.

Really nice puzzle! Quite a tough hybrid for me, since I am a beginner at yajilin, but I was happy to learn new things as my solve progressed! :-)
