How to Play Meowdoku

Meowdoku is a placement puzzle. You are not filling numbers into a grid. You are deciding which cells should contain cats while satisfying every row, column, color, and adjacency rule.

Goal

Place cats so that each row, each column, and each colored region has exactly one cat. When all constraints are satisfied, the puzzle is solved.

Rules

- Place exactly one cat in every row.
- Place exactly one cat in every column.
- Place exactly one cat in every colored region.
- Cats cannot touch, including diagonally.

First Move

Look for a color region with very few cells. If that region can only use one row or column safely, it may force the first cat.

If nothing is forced, mark impossible cells mentally: any cell next to a known cat candidate may be invalid depending on the final placement.

When Stuck

If the board stops making sense, upload a screenshot. The solver reads the colored regions, calculates a valid solution, and shows the solved image.
