It never seizes to amaze me how much reading the rules for a puzzle helps solving the said puzzle.
Very fun once I knew what I was doing.

Wonderful! Like many of the other commenters, I struggled at first with wrapping my brain around where to start, but that only made the moment it clicked all the sweeter! What an absolute delight to solve!

Maybe (like me) you forgot about the counting property of the circles and squares?

I forgot the entropy for the first 10 minutes hahaha What a beautiful gift that unwraps so beautifully!

It seems difficult to start then it’s loads of fun.

Took a bit for me to figure out how to start this one. Once I did it was a fast and simple solve. Great puzzle!

Found it more useful to mark parity than entropy, which is uncommon for high-entropy puzzles. Neat!

Easier than it looks, just ask the right questions. A true 1 star gem

Very nice - 35 minutes for me so I would increase the difficulty to 2 stars. Fun colouring adventure though.
