Catdunnit: Cat Mystery Sudoku

Someone gobbled Pip's sunflower seeds, and one of these cats did it!
Catdunnit is a cozy cat mystery logic puzzle game: pure logic, never a guess. Every case has exactly one answer, and the clues always get you there.
No lives to lose in a case, pencil notes for your maybes, and never a pop-up ad mid-case.

🔍 HOW A CASE WORKS
It plays like a sudoku-style logic puzzle with a whodunit on top:
• Every row and every column holds exactly one animal.
• No two animals touch, not even corner to corner.
• Each room hides exactly one cat. Pip shares a room with just one of them: the culprit.
• Some furniture blocks a square. Cats can sit on the seats.
• Every suspect has a clue card, and every clue is true.
Love murder mystery logic puzzles? This is the cozy version: the crimes are cat mischief, from stolen snacks to a squashed sun hat.

🐾 A DETECTIVE'S TOOLKIT
• Tap a suspect's card and the board lights up the squares their clues still allow.
• Double-tap a square to place them, tap once for an X: the same taps as the puzzle breaks.
• Hold a square to pencil in a maybe, and undo any slip of the finger.
• Press Check once everyone is placed to see if your plan holds.
• Stuck? Inspector Pounce walks you through the next deduction step by step, so you learn the logic instead of just getting an answer. A cat in the wrong place? The hint finds it first.
• Accuse whenever you're sure. An early arrest earns bonus treats; a wrong one costs a star, never the case.

🗞️ CASE CLOSED
• GUILTY! The floor plan fills in and the culprit confesses.
• Make the front page of The Daily Whisker, and share it with friends.
• Earn up to three stars a case and rise from Rookie Sniffer to Legendary Gumshoe.

🏡 200 CASES IN 10 PLACES
The Cozy Apartment, Cat Café, Farmhouse, Seaside Cottage, Bakery, Old Library, Toy Shop, Museum, Night Train and Snowy Lodge, each with its own rooms, furniture, crimes and regulars. Boards grow from 5×5 to 9×9, so the brain teasers go from gentle to a proper brain workout.

😼 16 SUSPECTS WITH SOMETHING TO HIDE
Mochi grooms extra hard after a crime. You can always hear Pepper coming. Meet every regular, their tells and their record in the Rogues' Gallery.

📅 A DAILY CASE
A new detective puzzle every day, the same for everyone: gentle on Monday, toughest on Sunday. Keep your streak going.

🧩 PUZZLE BREAKS
• Classic: one cat in every row, column and color, and no touching.
• Daily grid: a fresh Classic puzzle each day.
• Bedtime: every basket needs its own sleepy cat right beside it.
• Sniff: paw tiles count the cats around them, a little like minesweeper.
Every win pays a few treats, and every puzzle has one answer you can reach without guessing.

🛋️ THE DETECTIVE DEN
Spend treats on cat trees, donut beds, a cardboard castle and more. Seven rooms open one by one (the Den, Kitchen, Sunroom, Bedroom, Library loft, Toy attic and Lodge), and every piece you own earns cozy stars. The cats you've met drop by every six hours: pet them for a purr and a treat, and find each cat's favorite piece.

🎨 PLAY YOUR WAY
• No leaderboard to chase. Solve at your own pace.
• Color patterns put a little shape in every color, easier on colorblind eyes.

✅ ADS, PLAINLY
• Full-screen ads play only as a case or puzzle begins, never in the middle of one. A small banner sits below the board.
• Remove ads is a one-time purchase, not a subscription. It ends the full-screen ads and the banner for good.
• Reward videos (a hint, double treats) are always your choice.
• Or join the Detective Club: no full-screen ads or banner, unlimited hints and double treats on every case. The Club renews automatically until you cancel it in Google Play.

Grab your magnifying glass, detective. Pip is counting on you.
