(Eingestellt am 4. Februar 2026, 20:37 Uhr von Villse)
Next installment in the "Colours in he (k)night series, hope you enjoy! :)
Links to the previous parts of the series are given after the rules.
Normal Sudoku rules apply. Place the digits 1-9 once in every row, column and 3x3 box.
Anti-Knight: Cells separated by a knight’s move in chess cannot contain the same digit.
Palindromes: Digits along a grey line must read the same forwards and backwards.
XV: Cells separated by a V sum to 5; cells separated by an X sum to 10. Not all Vs and Xs are necessarily given.
Maximum: A cell marked with triangles pointing outward must contain a digit greater than the digits in all adjacent cells.
Minimum: A cell marked with triangles pointing inward must contain a digit smaller than the digits in all adjacent cells.

Happy solving!

Feels like the hardest puzzle in this series that I've solved, can't even understand why so many people describe it as "easy", the coloring is as hard as any of the others, but this one also has a very hard to find start point

I found this a very tough opening. The hardest of the other 2 star puzzles in the series. Perhaps I missed something. Once I’d broken in it was very smooth thereafter. Really fun series, thank you.

Took me 44 minutes to get a digit, then 3 more to finish the puzzle.
I did it with just careful colouring, making incremental progress.

Great puzzle. I used both letters and coloring to solve this one. Thank you!

I am also one of those who find letters much easier than colors for puzzles like this one. ABCD for low digits, and IHGF for their corresponding high-digit X-domino counterparts. E goes unused, since it is always 5. On top of the letters for this puzzle, I added a simple 3-color shading: green for low digits ABCD, gray for 5, and blue for high digits IHGF. The shading made it easier to see at a glance how the boxes and palindromes were filling up and what was missing. Using these techniques, it was an easy puzzle.

I find using letters instead of colors is easier for me, AB and CD = 5, AE, BF, CG and DH = 10 and I= 5. Eventually, I am able to fill the entire grid using these, then figuring out the actual values using the min/max is pretty straight forward

For me 3,5

You have to colour. There is no way around it.

Definitely one of the easier puzzles in the series, I took inder 25 minutes and never felt stuck, but without this being trivial.
If you are new to anti knight and colouring puzzles do give this a go. (I use four colours and the letters A to H to represent the four flavours of X pair, 5 doesn't get a colour or a letter. I find this easier to scan than trying to just use colours.)

there IS a narrow path to success here, starting with a careful study of the long palindrome, and leading to the result r6c4=2. after that, the rest is easy.
but claiming this puzzle is "easy" does not match reality.
incidentally, trying to fully colour the grid is counterproductive.

Pretty easy, but I think you have to be careful where you start—I had some crazy coloring for a while

Very nice

Lovely! But one of the easiest in the series for me, I’d say 1 star difficulty.
