Pupdoku: Dog Logic Puzzle

A cozy new logic puzzle starring Mushu the pup. Place one dog per row, column, and yard, and never let two touch. A fresh hand-crafted board every day.

Pupdoku is a cozy logic puzzle starring Mushu, a very good dog who just wants every pup to have a spot in the yard.

Each puzzle is a colorful grid, and the rules are simple to learn: place exactly one dog in every row, every column, and every colored yard. The catch is that no two dogs may ever touch, not even at a corner. Every board has a single solution, and you can always reach it by pure logic, so you never have to guess.

Hold a square to place a dog. Tap to leave a paw mark on a spot you have ruled out, and tap a dog to pick it back up. When you place a dog, the squares it rules out are marked for you, so the board fills in as you reason.

What is inside:

• 80 hand-crafted levels across four difficulties, from gentle Easy to tricky Expert.
• A brand new puzzle every day, with a streak calendar and paw-print history to keep your runs alive.
• Helpful hints that do not just point at a square, they explain why a dog must go there.
• Smart paw-marking, gentle sounds, and a happy wag when you solve it.
• Plays fully offline. No account, no login, and no ads interrupting your thinking.
• Your progress and daily streak are saved right on your device.

Whether you have two minutes in line or a quiet evening with a cup of tea, Pupdoku is a warm little brain break. Good dog.
