Nyandoku - Cat Logic Puzzle

Looking for a game that calms you down while keeping your brain awake?

Welcome to Nyandoku — a free logic puzzle game that takes the rigorous reasoning of Sudoku and
the tightening deduction of Minesweeper and hands it all to cats. There are no numbers to fill in.
Instead you work out where each cat belongs, using three rules and nothing else. No timers,
no pressure.

Your mission is simple: find the one right seat for every cat.

■ Three rules, deep strategy
• Exactly one cat in each colored region.
• Exactly one cat in each row and each column.
• Cats never touch. Not side by side, not diagonally.
The rules take three seconds to learn. But as the board grows you have to read two moves ahead
before you commit to one. Guessing will not carry you — this is a pure logic puzzle and real
brain training.

■ How to play
• Tap once — an X appears. That's your own note: "no cat can sit here."
• Tap the same cell twice — the cat moves in.
• Drag your finger to mark a whole run of cells at once.
Every puzzle has exactly one solution. Every clue you need is already on the board.

■ 300 handcrafted levels, then endless puzzles
300 levels from 4×4 up to 9×9, every one verified in advance. Difficulty doesn't climb in a
straight line — it rises and falls like a wave, so a hard board is followed by one that lets you
breathe. Once you clear all 300, Nyandoku keeps generating fresh ones. A free brain puzzle
with no finish line.

■ A daily puzzle, one a day
Every player in the world gets the same puzzle each day. Solved days are marked on your calendar,
and your streak is counted. Wake your brain up with one daily puzzle each morning.

■ Three hearts, and a flower grade
Every board starts with three hearts. A wrong placement costs one. However many hearts you
finish with becomes your grade — three hearts, three flowers. Combos and difficulty add to your
score, and your best score is kept separately for each board size.

■ Stuck? Take a hint
One hint is free every day. It opens a cell that logic has already settled, so you can keep
reasoning instead of guessing.

■ Global and country leaderboards
The daily puzzle has a leaderboard for that day, and there are separate global and country
rankings as well. No sign-up, no login — a nickname and a cat face is all it takes.

■ Free, offline, no account
Puzzles are built on your device. With no connection at all you can still play all 300 levels and
today's daily puzzle. Subway, plane, waiting in line — this is an offline brain puzzle that's most
useful exactly where the signal isn't. Nyandoku is completely free, and there is no account to make.

■ A good fit if you
• Enjoy Sudoku, Minesweeper, Nonograms — any puzzle solved by narrowing down the logic
• Want to concentrate quietly, without timers or an ad every thirty seconds
• Have ten minutes on the commute or before bed and want to use your head
• Are looking for a free puzzle game that works offline
• Like cats

■ Why Nyandoku stays on your phone
No daily check-in chores, no social mechanics pushed at you. One board, three rules, and a cat
that settles in when it finds its place. Seconds to learn, a long time to master — the logic puzzle
loop, kept intact. Beginners and seasoned solvers both start at the size that suits them.

■ 10 languages
English, 한국어, 日本語, Deutsch, Français, Español, Português (Brasil), Русский,

Nyandoku is free and supported by ads. An ad appears now and then between levels, and when you
want an extra hint or a heart back you can choose whether to watch one. That choice is always
skippable.
