How to Play Meowdoku

First, get to know the board

Look at the rows, columns, and colored regions before making a placement. Each needs one cat, and no two cats can touch, including diagonally. A small region can be a useful place to start because it has fewer possible squares.

Place a cat only when the constraints agree

Check a candidate square against its whole row and column. Then check the eight surrounding squares and the rest of its colored region. If a cat is already in any of those conflicting positions, that candidate cannot be used.

An X is a way to keep track of a square you have ruled out. Marking possibilities can make the next decision easier to see; it does not replace checking your reasoning.

Follow what each placement changes

After placing a cat, revisit the remaining regions. A placement can remove several possibilities elsewhere. If a row, column, or region has only one legal square left, that square is forced under the rules.

Try the visual demo

Tap a square on our sample to place a cat, tap it again for an X, and tap once more to clear it. Keyboard users can reach each square with Tab and activate it with Enter or Space.

Undo reverses the last edit, including a reset. New Puzzle switches between two fixed original samples and clears the edit history. This homepage demo does not offer hints or rule checking. The separate Solver provides those tools for manually entered puzzles.
