Solver, there's a fly on my Sudoku!

(Published on 25. November 2023, 22:39 by IcyFruit)

Normal sudoku rules apply. Digits separated by a white Kropki dot must be consecutive. Digits separated by a black Kropki dot must have a ratio of 1:2.

A fly has flown across the page, in orthogonal lines. It always went north from a cell containing a 2, east from a 4, south from a 6, and west from an 8. On odd digits, it kept going in a straight line. The fly entered the grid heading west at the arrow, and exited heading east at the bottom right of the grid. It did not leave and re-enter the grid at any point. The fly may have crossed its own path, but it never flew directly across a Kropki dot.

What a journey. I laughed, I cried, I swallowed a fly.

I kept thinking i had broken it. Very satisfying when it all comes together at the end.

I LOVED it. Great puzzle! I hope to see this ruleset more. The potential for crossing lines is something we don't see very often and that's too bad.

Excellent and devilishly clever! It feels like my brain was always overlooking the right path.

Very hard (but very satisfying) for me. My brain would just not let me see that possible path!
