Woofdoku

Overview
Woofdoku is a free logic puzzle game for Android from MTAG PUBLISHING LTD, first released on Google Play in July 2026 and updated to version 1.0.40 in October 2026. It mixes Sudoku-style deduction with Queens-style placement logic, but instead of numbers you place cheerful husky dogs on a bright, colorful grid. On Google Play it holds a 4.7-star rating from more than 620 reviews and has passed 10,000 downloads. The game is free to download and play, works offline, and is rated Everyone. It contains ads and offers in-app purchases from $1.99 to $104.99 per item. You need Android 7.0 or later to run it.

Gameplay
Each level gives you a square grid split into colored regions. Your job is to place exactly one husky in every row, every column and every colored region, with one strict rule: no two dogs may touch each other, not even at the corners. Tap a cell to place a dog, and tap it again to remove it if you change your mind. When every row, column and region holds exactly one dog and no two dogs touch, the level is complete and the next one opens up. Early boards are small and gentle, while later levels grow larger and use cleverer color layouts that demand real deduction. There are no timers, so you can think for as long as you like. If you get stuck, a Hint booster can reveal a correct placement, and a Magnifier helps you inspect the board more closely.

Features
Woofdoku keeps its feature list short and focused on the puzzle itself. The boards are filled with cute husky characters, and the bright, clean design keeps the grid readable. The game offers hundreds of hand-crafted levels, from easy introductions to genuinely demanding boards. Two boosters, Hint and Magnifier, are there for the moments when logic alone is not enough. There are no timers and no pressure to finish quickly, which gives the whole game a calm feel. It runs fully offline, and it is rated Everyone, so it suits younger players as well as adults.

Tips for new players
Start by looking for rows, columns or colored regions that have only one cell left where a dog can go. Those forced moves are the safest way to open a board. Remember the touching rule: a dog blocks its own cell and all eight cells around it, including the diagonals. Work from the smallest colored regions first, because a region with only two or three cells narrows your choices fast. If a placement leads to a dead end, remove dogs and try a different arrangement. Save your Hint boosters for the larger boards, where one revealed dog can unlock a whole chain of deductions. Finally, if two neighboring regions look alike, check the borders before you tap; a few players have found the teal and light blue regions hard to tell apart.

Pros and cons
Pros: The rules are simple to learn but the puzzles still demand real thinking, so it works for casual players and logic fans alike. The husky theme and bright design give it more charm than a plain number grid. There are no timers, the game works offline, and it is free to download. The difficulty rises gradually across hundreds of levels, and the Hint and Magnifier boosters help when you are stuck. Cons: Several players report that the instruction boxes at the top of the screen cover the top row of the board. A few players say the teal and light blue regions are hard to distinguish. The game contains ads and in-app purchases up to $104.99 per item. One player who finished level 200 found that no new level unlocked afterwards, which suggests the level count may be limited.

FAQ
Is Woofdoku free to play?
Yes. Woofdoku is free to download and play on Android, and it works offline. It contains ads and offers optional in-app purchases from $1.99 to $104.99 per item, but you can play through the levels without buying anything.
What are the rules of Woofdoku?
Place exactly one husky in every row, every column and every colored region, and make sure no two dogs touch each other, not even diagonally. Tap a cell to place a dog and tap it again to remove it. When every row, column and region has exactly one dog, the level is complete.
Why can't I see or tap the top row of the board?
Some players have reported that the instruction boxes shown at the start cover the top row of cells. If this happens to you, try dismissing the instructions first; if the boxes do not move, restarting the level may help. The latest update notes only mention bug fixes, so no fix for this has been listed yet.
