Catdoku: Cat Sudoku Logic

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 every one of them is
solved by reasoning alone. 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: this is the shape of Sudoku with cats in place of digits.

You never guess. You cross out what is impossible until a single square is left,
and every placement tightens the board in a chain: it blocks a row, a column, a
territory and the eight squares around it. Keep going and the answer becomes
inevitable.

NEVER A LUCKY GUESS

Every hand-built 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.

BEAT THE CLOCK, 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
finishing sharply is worth something — and letting it run out costs a life, the
same as running out of hearts.

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. The hint marks the square the next cat goes
on and names the row, column or territory that forced it. That is the deduction,
in one line: not a walkthrough, and never 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. The 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.

NO TIMERS, NO PRESSURE, WHENEVER YOU WANT

Not every session wants a clock. The calm run deals you 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. Play it for as long as you
like.

A NEW PUZZLE EVERY DAY

Today's puzzle is the same board for everyone, everywhere, and a new one arrives
each day. Beat it and your streak grows. It needs no account and no connection —
the date is the only thing it asks for.

DRAWN, NOT PHOTOGRAPHED

A soft plush cat, and everything around it — paw prints, hearts, stars, fish —
drawn from shapes as you play, so it stays razor sharp on any screen and the
whole game is a small download.

GatitoSudoku is free to play. 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.

It includes optional rewarded ads you choose to watch, and optional in-app
purchases. 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.
