Yangdoku: Logic Puzzle

Step into the world of Yangdoku.
It is a calm logic puzzle where sheep, wolves, and shepherd clues replace numbers.

🐑 What kind of game is Yangdoku?

Each color region has exactly one sheep.
Each wolf must see a sheep first in the direction it faces.
Each shepherd must have exactly one sheep in the surrounding eight squares.

The rules are short, but the board asks you to think.
Find which squares must be sheep, mark which squares must be X, and narrow the puzzle one step at a time.

✨ Why Yangdoku feels good to play

◆ Logic, not guessing
Every release puzzle is checked to have one solution.
You are not tapping by instinct; you are building reasons until the board is complete.

◆ Hints that explain the reason
When you get stuck, hints do more than reveal an answer.
They show why a square must be sheep or why it must be X, helping you find the next step yourself.

◆ Ads do not break the flow
There are no banner ads and no forced interstitial breaks.
Rewarded ads appear only when you choose to watch one for extra hints or the memo tool, and you can keep playing without watching any.

◆ A challenge that grows slowly
Early puzzles start gently, then wider boards and deeper reasoning patterns appear as you progress.
Play for a quick break or settle in for a slower puzzle session.

🧩 If you want to solve better
