Counting on Quiet Knights
(Published on 11. January 2025, 22:07 by Jolly Rogers)
RULES:
- Normal Sudoku rules apply.
- A digit in a circle indicates how many times that digit appears in a circle.
- Also, digits in a circle must differ in value by at least 5 from every cell a (chess) knights move away.
- For example: the circle in r1c1 must differ by at least 5 from cells r2c3 and r3c2.
- Digits in a grey square must be even.

Hope you enjoy.

I felt so smart after figuring out that we had to color the grid. Thanks! Nice puzzle.

I spent most of my solve saying "no way this has a unique solution!" as I gradually filled in all of the digits.

That was most enjoyable; amazing how so few clues could lead to a unique solution but it really did.

Really fascinating! Took a long while to strategize initially, but then it just flowed beautifully.

I was a bit impressed that so few clues actually resolved in the end. Simple but graceful solve, with some "oh, you clever thing" moments.

I needed some time to come up with a strategy, but little by little it developed. The combination of German whisper and knight move is an interesting combination. It was fun.
