Catdoku Sudoku Puzzle

Catdoku Sudoku Puzzle is a region-placement logic puzzle with cats. The grid is divided into colored territories, and the rules are strict: each territory holds exactly one cat, no two cats share a row or column, and no two cats may touch, including diagonally. A single placement therefore eliminates a whole row, a whole column, and every square around it, and the challenge is deducing where each cat must go rather than trying spots at random.

It is a strong fit for a quick browser session because the levels are short and the rules never change, so you can start a puzzle in seconds. The early boards introduce the rules gently, and later ones need deeper chains of reasoning. Wrong taps cost hearts, which keeps you honest without a timer. The flexible layout and simple tap input make it comfortable on a phone in either orientation, on a tablet, or with a mouse on a desktop. The cat theme softens the look, but the puzzle underneath is rigorous. The developer stresses that every cat should be placed for a clear reason, and the pleasure comes from spotting a square that must hold a cat, placing it, and watching the rest of the grid open up as a result.

It suits Sudoku players, fans of logic grids, and anyone who likes a clean puzzle where every answer can be proven. If you enjoy star-battle or queens-style placement puzzles, nonograms, or other pure deduction games, this is the same kind of satisfaction with a friendlier look. Newcomers to logic puzzles can start here too, and they will pick up techniques that carry over to other grid puzzles, since the gentle opening boards teach the rules one at a time before the harder grids arrive.
