GatitoSudoku: Cat Sudoku Logic

A campaign that never runs out: 96 hand-verified boards open the road, and the chapters keep coming. Every level is solvable by reasoning alone — never a lucky guess.

GatitoSudoku is a cat sudoku logic puzzle — also known as Star Battle, Queens or Two Not Touch. Every level is pure deduction: never a lucky guess. Place exactly one cat per row, column and colour.

Every level is a grid split into coloured territories, and four rules apply at once:

• one cat per row • one cat per column • one cat per territory • no two cats may touch — not even diagonally

No numbers anywhere: a brain puzzle with the shape of Sudoku and cats in place of the digits. You cross out what is impossible until a single square is left, and every cat you place blocks a row, a column, a territory and the eight squares around it.

NEVER A LUCKY GUESS

Every level 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.

HINTS THAT EXPLAIN, AND KEEP COMING BACK

Hints are never sold, for fish or for money. You get three, and another arrives for every three new levels you beat. A hint marks the square the next cat goes on and names the row, column or territory that forced it — the deduction in one line, not the rest of the board.

A CAMPAIGN THAT NEVER RUNS OUT

96 hand-verified boards open the road, and the road does not end there. Chapters keep coming, eight levels each, from gentle 5×5 boards up to 12×12 monsters, and every chapter ends with a boss. Board size inside a chapter is deliberately unpredictable, so a small board can follow a large one and give you a breather.

CALM RUNS, AND A NEW PUZZLE EVERY DAY

Not every session wants a clock. A calm run deals a board off the road with no countdown and nothing at stake — a wrong cat costs you nothing but the time to think again, and there is no way to lose. And today's puzzle is the same board for every player everywhere, with a new one each day. Beat it and your streak grows. Neither needs an account or a connection — the whole game plays offline.

ADS, IN PLAIN TERMS

Ads pay for the game, so here are the terms before you install. A banner on the map and the menus, never on a puzzle. One full-screen ad after about every third level you finish, and never two close together. And rewarded videos you can choose to watch for a life or for fish — a way to earn, never a toll, with nothing in the game locked behind one.

One purchase of 3,99 EUR or the same in your currency removes the banner and the full-screen ads for good. It deliberately leaves the rewarded ones, because those are a way to earn rather than an interruption, and the shop says so on the card.

You get three lives; losing a level or walking out of an unfinished one costs one, and a fresh life arrives every 25 minutes on its own. Fish are the in-game currency and buy lives, boosters and cat skins — winning levels and claiming the daily reward earn them for nothing. Skins change how your cat looks and nothing else, and there is no booster that does the reasoning for you: a deduction game that sold you an advantage would stop being a deduction game.
