Three cozy rules
1 Balance the cats
Each row and column ends with the same number of orange day-cats and black night-cats.
2 No three in a row
Never place three of the same cat next to each other, across or down.
3 Mind the badges
An = badge means the two joined cats match; an × badge means they differ.

Meet the cats
The sunny one (☀️). Its round orange face means daytime.
The dreamy one (🌙). Its dark sleepy face means night.
The two cats have different faces and fur, so you can always tell them apart — never by colour alone.
