- One cat per colored room.
- One cat per row and column.
- No touching, even diagonally.
Row Rule
A completed row contains one cat. Once a cat sits in a row, every other cell in that row is no longer available for cats.
Column Rule
A completed column contains one cat. Columns combine with room boundaries to create strong locks and forced placements.
Neighbor Rule
Cats cannot be neighbors, including diagonally. In Meowdoku, diagonal contact is just as illegal as side-by-side contact.
Hearts and Mistakes
Hearts are feedback, not the puzzle engine. The logic remains the same: place carefully, learn from the blocked cell, and keep the board clean.
