Wangdoku: Doggo Logic Puzzle

About this app

Wangdoku is the cozy logic puzzle where cute dogs meet clever deduction. Blending the best of Sudoku, Minesweeper, and the classic N-Queens puzzle, every level is a satisfying test of pure reasoning—no luck, no guessing, just that "I figured it out!" feeling. Your goal is simple to learn but delightfully tricky to master: place one dog in each colored region of the board, following four golden rules. Solve it, and the pups are happy! THE RULES - One dog per colored region - No two dogs in the same row - No two dogs in the same column - Dogs can never touch—not even diagonally That last rule is where the real brain-teasing begins.
