About PetDoku
PetDoku is a logic puzzle about working out where the pets are hiding. Every board is divided into colored regions, and exactly one pet belongs in each region — and in each row and each column. Pets are shy: no two of them may sit next to each other, not even diagonally.
There is no guessing. Every one of the 10,000 stages is checked by a solver so that it can be reached by reasoning alone. Five difficulties take you from a gentle 5x5 board up to a 12x12 challenge, with hints ready whenever you want one.
How to Play
- Tap a square once to mark it with X — that is how you rule places out.
- Double-tap a square (or press and hold) to place a pet there.
- One pet per colored region, per row and per column — and no two pets may touch, diagonals included.
- You have three hearts. Placing a pet where the logic rules it out costs one.
