Anti-Anti-Knight II(Whispers/Kropki)

(Published on 23. August 2026, 17:40 by Kutsumi Hane)

Rules:

(This puzzle is a different take on my earlier puzzle: [Anti-Anti-Knight (Whispers/XV/Kropki)])
Normal Sudoku rules apply, requiring that each row, column, and 3×3 box contains the digits 1-9 exactly once. Additionally:
    ·Toroidal Grid: The grid wraps around both horizontally and vertically;
    ·Anti-Anti-Knight: Every cell has at least one knight-move neighbor with the same digit;
    ·German Whispers: Adjacent digits on green lines must differ by at least 5;
    ·Kropki Dots: Black dots indicate a 1:2 ratio between the digits.

    Here you can solve the puzzle online:

    The difficulty is probably 3-4 stars. I wish you joyful solving!

    Hint:

    · Start with the high-low alternation on each German Whispers line.
    · During the solve, it may be helpful to check each cell's candidates against those of its knight-move neighbors – if a digit doesn't appear in any neighbor's candidate list, it can't go in that cell.

    Solution code: Column 9

    The amount of toroidal knight moves had my head spinning, but a very ingenious construction I enjoyed quite a bit. Thank you, Kutsumi Hane.
