Knight of the Hill
(Published on 7. August 2026, 11:42 by lgastako)
This one is a little tougher than the GAS's I've been creating lately, but hopefully still fun for a wide audience. As always, the more feedback, the better. Enjoy!
- Normal Sudoku Rules: Fill each row, column, and 3x3 box with the digits 1-9 once each.
- White Kropkis/Black Kropkis: Digits in cells separated by a white dot are consecutive. Digits in cells separated by a black dot have a 1:2 ratio.
- Whisper-5 Lines: Along green lines, digits must differ from their neighbors by at least 5.
- Whisper-4 Lines: Along orange lines, digits must differ from their neighbors by at least 4.
- Whisper-3 Lines: Along yellow lines, digits must differ from their neighbors by at least 3.
- Whisper-2 Lines: Along purple lines, digits must differ from their neighbors by at least 2.
- Renban: Pink lines contain a non-repeating set of consecutive digits in any order.
- Knight's Move: Cells a (chess) knight's move apart cannot contain the same digit.
Solution code: Row 2, in order, from left to right.

I feel like the overcrowding of the lines is the point of this puzzle. You need to carefully remove some numbers based on it... Then the knight does the magic. Loved it :)

Updated Renban color to pink.

I’m afraid there’s quite a big problem with the look of the grid. I’d suggest making the lines thinner and using a different colour scheme (maybe with shapes to distinguish the lines). It’s just too crowded and impossible for some solvers.
Sorry. ❤️

(The Pi Guy) General issues with the yellow colour and similarity of some of the lines, as well as overcrowding.
