Puppy Logic

Puppy Logic is a calm, dog-themed logic game built around clear rules and satisfying deductions.

How it works
Place exactly one puppy in every row, column, and colored region. Puppies cannot touch, even diagonally. Tap a square to rule it out with an X, double-tap to place a puppy, and swipe to rule out a whole run at once. Every level has exactly one solution, and the three rules stay on screen above the board so you never have to go looking for them.

Every guess counts
Each level gives you three biscuits. Put a puppy where one cannot go and it costs a biscuit, so the board pushes back and solving it is something you earn. Run out and you can start the level over, or watch an optional ad to carry on with the board you already have.

A Coach that explains
Puppy Coach reads the board, tells you which rule applies right now and why, then offers to carry that step out for you. Show Move simply points at a move when you would rather not think it through. Each tool comes with free uses to start; after those, one optional ad adds one use to your count, and it stays there until you choose to spend it. Clearing your own X marks and restarting a level are always free.

Plenty to solve
Work through 1,000 original levels on boards from 4x4 up to 10x10. The puzzles follow how you play: clear them cleanly and they get harder, get stuck and they ease off, and every tenth level from 21 is a marked hard one. Choose any unlocked level, keep a separate unfinished board for each one, and return later without losing your place. A Daily Puzzle gives you another reason to come back.

Fair by design
Every puzzle plays offline. There is no account and nothing to buy. Every ad is clearly labelled: the banner below the board appears only after you have finished ten levels and come back for a second session, and a rewarded ad is never forced - watching one is always your choice. Progress and settings stay in Android app storage, although Android may include them in your Google account system backup.

Recent changes:
The difficulty now follows how you play. Clear levels cleanly and the puzzles get harder; get stuck and they ease off. Boards run from 4x4 up to 10x10, and every tenth level from 21 is a marked hard one. The opening levels are gentler, and the free starter puppy steps back gradually instead of vanishing all at once. Levels you had in progress start over, because every board in the game is newly built.
