Small Latin Y²
(Published on 27. October 2025, 08:00 by Kaktuslav)
Rules: Place the digits 1–6 exactly once in each row and each column.
Yin-yang: Shade some cells so that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2×2 area is entirely shaded or entirely unshaded.
YY cages: Within each cage, the sum of the shaded digits equals the sum of the unshaded digits. Digits MAY repeat within a cage.
Odd circle: The digit in a gray circle is odd.
Solution code: Row 3 with dashes for shading changes (e.g. 1-23-456)

Very nice, lovely ruleset. I got stuck near the end and could only proceed with a difficult chain, but that is probably me missing something obvious. Thank you

Very nice! This one reminded me of a great puzzle by Jay Dyer called Birefringence. Thank you very much for creating and sharing this lovely snack.

Nice and quite an approachable puzzle by Kaktuslav but it's still more like 3* than 2*.
Thanks!

Nice puzzle. But not so easy as it looks at first glance. Thanks.
