Puppydoku: Logic Puzzle

Find every hidden puppy using pure logic — no guessing, ever.

Puppydoku is a cozy brain puzzle in the star battle / queens family. Every board is a grid split into colored areas, and every row, every column and every color hides exactly one sleepy puppy. Rule out the cells that can't work, place the puppies, and finish the board with logic alone.

🐶 FOUR SIMPLE RULES
• One puppy in every row
• One puppy in every column
• One puppy in every color
• Puppies need space — they can't touch, not even corner to corner

Tap a cell to mark ✕. Double-tap to place a puppy. Press and drag to sweep ✕ across a whole line. That's the entire game — the rest is your brain.

🧠 NO GUESSING. NOT ONCE.
Every level was checked by a solver before it shipped: exactly one solution, and a path to it built only from moves a human can actually see. No 50/50 coin flips, no backtracking, no "restart and hope." If you're stuck, there is always a next move waiting to be found — and finding it is the whole pleasure.

🧩 11,000 PUZZLES ACROSS 8 WORLDS
Start on gentle 5×5 boards and grow into 12×12 master grids:
• Puppy School — 5×5, beginner
• Backyard — 6×6, easy
• Dog Park — 7×7, medium
• Beach Walk — 8×8, medium+
• Snow Trail — 9×9, hard
• City Streets — 10×10, hard+
• Mountain Camp — 11×11, expert
• Dream Kennel — 12×12, master
Each world brings a new look, a new accessory for your pup, and a real step up in difficulty.

💡 HINTS THAT TEACH, NOT HINTS THAT TELL
Stuck? A hint highlights the row, column or color that matters and explains the reasoning in one plain sentence — "Lavender only fits in row 2, so the rest of row 2 is clear." You don't just get the answer handed over, you learn the technique and spot it yourself on the next board.

📅 DAILY CHALLENGE & STREAKS
One fresh puzzle every day, the same board for every player in the world. Solve it to grow your streak, watch your week fill in, and collect a gift of hints every seventh day in a row.

🦴 THREE BONES — OR NONE AT ALL
Place a puppy where one can't be and you lose a bone; run out and the level starts over. Prefer to think without a clock on your shoulder? Switch on Relaxed mode: no lives, no fails, just you and the grid for as long as you like.

⭐ STARS, TIMES AND SCORES
Earn up to three stars on every level — a perfect run means no hints and no mistakes. Chain correct placements for combo points, beat your own best time, and push your best score on boards you've already cleared.

🔧 TOOLS THAT RESPECT YOUR TIME
• Unlimited undo
• Auto-cross clears the obvious cells for you
• Optional mistake checker for your ✕ marks
• Color-blind friendly pattern overlays on every region
• Sound, music and haptics, each on its own switch

🐾 LEARN IT IN THIRTY SECONDS
Three swipe cards teach the rules, and the first levels are guided — a friendly paw points at the next logical move until the pattern clicks. No manual, no tutorial you have to sit through twice.

✈️ 100% OFFLINE, NO SIGN-UP
Every puzzle is already on your device. Play on a plane, on the subway, in a waiting room — no internet, no account, no login. Your board saves itself when you leave, so you pick up exactly where you stopped.

🌍 PLAY IN YOUR LANGUAGE
English, 日本語, Español, Deutsch, Português, 한국어, Türkçe and हिन्दी.

🐕 MEET BISCUIT
A soft-eared little pup who waits beside the board, thinks hard with you, naps when you're gone, and throws a shower of bones every time you finish.

Perfect for quiet moments and long brain workouts alike — a five-minute 5×5 before bed, or a 12×12 you chew on all afternoon. If you love Sudoku, nonograms, minesweeper, kakuro or logic grid puzzles, this one is for you.
