Yin Yang Counting Circles
(Published on 20. February 2024, 12:26 by Dag H)
Rules:
Normal sudoku rules apply.
Yin Yang: Color the entire grid in two different colors, so that a) each color constitutes one orthogonally contiguous region, and b) no 2x2 square of cells is entirely one color.
Counting Circles: A digit in a circle indicates how many times that digit appears in circles.
All odd digits in circles are one color, all even digits in circles are the other color. White dots separate consecutive digits of opposite color.

A super fun intro-to-yin-yang puzzle I think? I don't think the logic is too hard though I did break it a couple of times - I think what was happening was I kept accidentally applying the parity rule to shaded digits even though they did not have circles :D

I loved the puzzle! A 2-star difficulty if you know the tricks of this type of variant. Thank you for setting this beautiful puzzle!

This was a cool puzzle, thought I’d found the break in pretty easily but got quite a bit stuck until I realised what the true break in was. Very good fun. Always love a good Yin Yang and this was very good.

Very pleasant accessible puzzle. I loved the interaction of Ying-yang and counting circles.
In my opinion this is a 2 star difficulty.

I'm not typically the biggest fan of counting circles, but this worked very well with Yin Yang to create an incredibly enjoyable puzzle, thanks!
