I've solved all four puzzles in this incredible collection, and this is my favorite. Even though I found it the easiest one, it's just sublime and perfectly realized. And those Dutch whispers, so on theme!

Wow another stunner! It’s unbelievable how each puzzle in this series fits so well and is so unique amongst each other. I enjoyed every second of this puzzle even though many of those were downloading the desmos app to better track my thoughts

Another beautiful work! 3* for the very elegant break-in, then smooth 2* solving for the remainder.

Somehow the phone version is just a white canvas, so I have to switch devices to solve this lovely puzzle.

Took me about 30 minutes to spot the quite unique break-in. From there on it would have been a pretty smooth solve if I hadn't spent another 30 minutes to spot one simple deduction.
This puzzle is a piece of art.
