Purrdoku: Cat & Animal Sudoku

Sudoku met a kitten, and logic got adorable.

Purrdoku is the cozy cat sudoku puzzle where pure logic — never luck — decides every move. No numbers, no math: every board is a grid of colored regions, and your job is to seat exactly one cat in every region while keeping them out of each other's rows, columns and corners. If you were looking for a cat sudoku, an animal sudoku, or just a properly cute logic puzzle, you found the right app.

HOW TO PLAY (you'll get it in 10 seconds)
- One cat per colored region — every region, exactly one
- One cat per row and per column — no roommates
- Cats never touch, not even corner to corner — personal space is sacred
- Tap once for an X note, tap again to place a cat
- 3 hearts per puzzle — a wrong cat costs one, so think before you tap
- Stuck? Two hint types are one tap away

Every puzzle is generated fresh with exactly one solution, solvable by pure deduction — never a guess, never a dead end. Boards start at a friendly 5x5 and grow into big, brain-bending grids as you climb. Unlimited levels, forever.

A CAT SUDOKU THAT RESPECTS YOUR BRAIN
This animal sudoku is not the classic 9x9 number grid. Instead of digits you place cats, and instead of arithmetic you use deduction: cross out what cannot work, and what remains is the answer. Fans of color-region logic puzzles, nonograms, and daily brain teasers will feel at home in minutes — and anyone who has never touched a sudoku can learn the whole game in one screen.

Whether you come from classic number sudoku, from cat sudoku and animal sudoku games, or straight from a cat video rabbit hole, Purrdoku rewards patience over speed and calm over chaos. Open it for two focused minutes between meetings, or sink into a long session — it respects your brain either way.
