Four Rules. That Is the Entire Game.

GatitoSudoku is not a Sudoku — there are no numbers anywhere. Every level is a grid split into coloured territories, and you place exactly one cat in each of them while obeying four constraints at once. Learn them in ten seconds, spend hours on them.

Rule 01

One Cat per Row

The moment a cat lands, its entire row is spoken for. Nothing else can sit on that line.

Rule 02

One Cat per Column

Same again, vertically. Every placement kills a row and a column in one move.

Rule 03

One Cat per Territory

Each coloured region holds exactly one cat — no matter how oddly it is shaped.

Rule 04

No Two Cats May Touch

Not even at the corners. Each cat also blocks the eight squares around it — the rule that turns a grid into a chain reaction.

Hand-Drawn Boards, From 5×5 Up to 12×12

A soft plush cat and everything around it — paw prints, hearts, stars, fish — drawn from shapes as you play. Razor sharp on any screen, and a tiny download.

Never a Lucky Guess. Not Once, in Any Level.

Every one of the 96 levels was checked three ways before it shipped: it has exactly one solution, and it can be solved step by step by reasoning alone. If you are stuck, there is something there to find. That is a guarantee, not a figure of speech.

1

Exactly One Solution

An exhaustive solver proves each board has a single answer. It has to — the hearts rule compares your move against the true solution.

96

Levels, All Verified

A human-style deduction solver replays every level from scratch. If it cannot get there by reasoning, the level does not ship.

0

Coin Flips Required

You cross out what is impossible until a single square is left. Keep going and the answer becomes inevitable.

The Hint Explains Itself

Most puzzle games point at a square and leave you none the wiser. A GatitoSudoku hint tells you which rule applies and which squares prove it — it is a teacher rather than an answer key, so you finish the game better at it than when you started.

  • Named deductions. The reasoning is spelled out in plain words, with the squares that prove it highlighted on the board.
  • A hint never costs a star. Take one whenever you are stuck without wrecking your rating.
  • Optional auto-dimming. Turn on automatic dimming of squares that are already impossible, if you want the board to do the bookkeeping.

Finish Sharply, Keep the Change

Every level runs on a timer set with room to think rather than room to panic. Whatever is left on the clock when the last cat lands is paid out in fish — so a clean, quick solve is worth something.

  • Three hearts per level. A wrong placement costs one; run out and the level is lost.
  • Three lives overall. Losing a level — or walking out of an unfinished one — costs a life, and a fresh one arrives on its own every 25 minutes.
  • Fish are earned, not required. Win levels, beat the clock and claim the daily reward. Spend them on lives, hints, boosters and cat skins.
  • Nothing does the reasoning for you. Skins change how your cat looks and nothing else — a deduction game that sold you an advantage would stop being a deduction game.

96 Levels, 12 Chapters, Eight Difficulty Tiers

From gentle 5×5 boards up to 12×12 monsters. Board size inside a chapter is deliberately unpredictable, so a small board can follow a large one and give you a breather — but the difficulty keeps climbing, and every chapter ends with a boss. Finish the pack and the campaign doesn't stop: it keeps dealing boards turned and mirrored through the puzzle's own symmetries, holding at the hardest tiers, for as long as you keep playing.

A Boss Closes Every Chapter

Twelve chapters of eight levels. A chapter opens once the previous one's boss has been beaten.

Four Plush Cats to Collect

Each with its own moods. Cosmetic only — they never touch the puzzle.

Plays Fully Offline

No account, no sign-up, no connection needed. Solve on the train, in a queue, anywhere.

The Campaign Never Really Ends

Clear all 96 and the boards keep coming — turned and mirrored through the puzzle's own symmetries, at the hardest tiers, for as long as you want to keep playing.

How to Play GatitoSudoku

No tutorial to sit through. Four gestures cover the whole game.

Tap to Mark

A tap cycles a square between empty and a paw print. Paws are your notes — the squares you have ruled out.

Double Tap to Place

Sure about a square? Double tap and the cat lands there. Wrong guesses cost a heart, so make the deduction first.

Drag to Cross Out

Drag across a run of squares to cross them out — or un-cross them — in one sweep. On desktop, the right mouse button does the same.

Pinch on Big Boards

The 11×11 and 12×12 boards zoom and pan with a pinch, so even the Legend tier stays comfortable on a phone.

Frequently Asked Questions About GatitoSudoku

No — there are no numbers in GatitoSudoku at all. Each level is a grid divided into coloured territories, and you place exactly one cat in every row, every column and every territory — with the extra rule that no two cats may touch, not even diagonally. It is a constraint-elimination puzzle, closer to a non-attacking kings puzzle than to Sudoku.
Never. All 96 levels were checked three ways before shipping: each has exactly one solution, and each can be solved step by step by reasoning alone. If you are stuck, there is always something on the board left to find.
Yes, GatitoSudoku is free to play. It includes optional rewarded ads you choose to watch and optional in-app purchases. Skins only change how your cat looks, and no booster does the reasoning for you.
Yes. The whole campaign plays fully offline, with no account and no sign-up. Everything is drawn from shapes as you play, so the download stays small and stays sharp on any screen.
Most puzzle games point at a square. A GatitoSudoku hint tells you which rule applies and which squares prove it, so you learn the deduction instead of being handed the answer. A hint never costs you a star.
Hearts are your mistakes inside a level — you get three, and running out loses the level. Lives are your attempts across the game — you also get three, losing a level costs one, and a fresh life arrives on its own every 25 minutes. Fish are the in-game currency: you earn them by winning levels, by the time left on the clock and from the daily reward, and you spend them on lives, hints, boosters and cat skins.
From gentle 5×5 grids up to 12×12 monsters, across eight difficulty tiers: Easy, Simple, Medium, Hard, Master, Expert, Feline and Legend. The board size inside a chapter is deliberately unpredictable, so a small board can follow a large one and give you a breather, while the difficulty keeps climbing.
Your progress is stored on your device and the game needs no account or sign-up to play. The full privacy policy covers what the optional ads and in-app purchases involve.
Yes, both. GatitoSudoku is live on the App Store for iPhone and on Google Play for Android. It is the same game on either platform — the same 96 levels, the same rules and the same hints — and it is free to play on both.
The campaign keeps going. Once the 96-level pack is done, every board comes back turned or mirrored through the puzzle's own symmetries — a fresh layout that still shares its bones with one you already solved — and the difficulty settles in at the hardest tiers and stays there. There is no final level.
