Welcome to Animal Doku — a charming brain teaser that takes the addictive logic of Sudoku and "Queens"-style puzzles and wraps it in a world of adorable animals. 🐱🐘🐼 Each level is a grid split into colored regions, and your job is delightfully simple to learn but tricky to master: place exactly one animal in every color so that no two animals share a row or column — and none of them touch, not even diagonally.
