X---V*Lines

(Published on 4. October 2025, 18:47 by NurglesGift)

Normal sudoku rules apply.

Renban = Cells along a pink line must be a set of consecutive digits in any order.

Whisper = Adjacent digits along a green line must differ by 5 or more.

Mod-3 Lines: Every three adjacent digits along a blue line must contain a set of digits that have different remainder modulo 3. ie: one from(1,4,7) one from (2,5,8) one from (3,6,9).

Orthogonally adjacent cells can not sum to 5 or 10.

Two lines of the same length and same color are connected X lines.

Counting from the bulb, the first cell of each connected X line sum to 10. the second cell of each line sum to 10 etc.

That wasn't exactly easy.

Thanks for this, very enjoyable solve! I normally shy away from puzzles involving renban/mod-3 lines as I'm very bad at properly utilizing the logic behind them, but found it very beautiful in this puzzle - think there could be a lot of potential for whisper lines in your XV puzzles in particular!
