Rules:

1. Normal Sudoku rules apply. Fill the grid with digits from 1 to 9 with no repeats in any row, column, or box.

2. Chinese Whisper Line: Adjacent digits along a yellow line differ by at most 2. Adjacent digits may be equal if allowed by other rules. Gray lines are for aesthetic purposes only.

3. Partial Anti-knight: Two cells may not contain the same digit if they are separated by a knight’s move AND they are visited by any of the Chinese Whisper lines. Note that r5c5 is also visited by a Chinese Whisper line.

4. Kropki: A white dot indicates the difference of two digits it separates. A black dot indicates the ratio of two digits it separates. Not all dots are necessarily given.

No trial-and-error is required.
