Singleton region
A color with only one cell must hold the cat. Scan region sizes at the start for free placements.
Meowdoku strategy guide
The goal is a repeatable elimination rhythm — not faster tapping. These techniques solve most boards with forced moves.
Unique cell in a row/column
If a row or column has only one remaining legal cell after elimination, place there — classic “last remaining” logic.
Region candidate squeeze
For each color, list cells still free of row/column/diagonal blocks. One candidate → place; two → light casework.
Diagonal block chains
Each cat forbids eight neighbors. Two cats can squeeze a third region’s candidates into a forced cell.
Starter-cat anchors
Locked cats are free information: mark row, column, and 8-adjacency immediately, then re-check regions.
Proof by contradiction + undo
Late-game with two options, try one briefly. If a color loses all legal cells, the other option is true. Undo beats full restarts.
Recommended thinking order
- Starter cats → draw forbidden zones
- Singleton colors → forced placements
- Update row / column / diagonal marks
- Region and line uniqueness
- Branch only when needed
Common mistakes
- Forgetting diagonals: an “empty” cell may be corner-blocked.
- Placing without updating marks: candidates go stale.
- Guessing among 3+ candidates: fish tokens vanish fast.
