Catdoku! Cat Sudoku Puzzle

Place one cat per region. No ads. No in-app purchases. Just pure logic.

Catdoku! is a cozy logic puzzle game where you place exactly one cat in each colored region of an N×N grid. Sounds simple — but each cat needs its own row, its own column, and cats can never touch, even diagonally. Every puzzle has one perfect solution.

HOW TO PLAY • Single tap to mark a cell with an exclusion X • Double tap to place your cat • Wrong placements cost a heart — three wrong moves and the puzzle resets • Work through the logic and every solution clicks into place

317 HAND-TUNED LEVELS Start with a cozy 6×6 grid and work your way up through 7×7, 8×8, 9×9, 10×10, and finally 11×11 boards. Every level is hand-crafted and has exactly one correct solution — no guessing, pure deduction.

100% FREE · ZERO ADS · ZERO IN-APP PURCHASES No banners. No pop-ups. No ads mid-puzzle. No ad after every level. No paywall, ever. Catdoku! is completely free and will stay that way.

FULLY OFFLINE No account. No internet. No tracking. Play on a plane, in the subway, or anywhere else. Your progress saves automatically.

FAMILY FRIENDLY Rated 4+ with no violent content. Perfect for all ages — anyone who loves logic puzzles, sudoku, or cute cats will feel right at home.

THE LOGIC Each colored region gets exactly one cat. Each row gets exactly one cat. Each column gets exactly one cat. And no two cats can ever be adjacent — not even diagonally. These four rules are all you need. The depth comes from the board layout.

If you enjoy Queens, sudoku variants, or logic grid puzzles — Catdoku! was made for you.
