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.

Unique way of using the knight rule, very enjoyable, thank you!

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.
