## What is Binairo?

Fill the grid with 0s and 1s. Just three simple rules.
Binairo — also known as Takuzu or Binary Puzzle — is pure logic. No luck, no math.
A calm, beautifully minimal way to sharpen your mind, anytime, anywhere.

■ How to play
Put a 0 or a 1 in every cell. Follow three rules and fill the whole board:
- Never three of the same number in a row or column
- Each row and column has an equal count of 0s and 1s
- No two rows and no two columns are identical
No prior knowledge needed — most people are playing within minutes.

■ Features
- Always solvable by logic: every puzzle is verified in-app to have exactly ONE
  solution, so you never have to guess.
- Four difficulties: from a gentle 6x6 to a demanding 12x12.
- Daily Challenge: everyone plays the same puzzle each day, with streaks and a
  calendar to keep the habit going.
- Two display styles: numbers (0/1) or two-color stones — your choice.
- Gentle assists: mistake highlighting, remaining counts, undo, and hints.
- Fully offline: play anywhere, even with no signal.
- Private by design: your records stay on your device.

■ Great for you if…
- You've mastered Sudoku and want your next logic fix
- You love pure logic with zero luck involved
- You're tired of cluttered, ad-heavy, subscription puzzles
- You want a calm mental reset on the commute, on a break, or before bed
- The idea of 0s and 1s makes you smile

■ Privacy & peace of mind
- No account or sign-up required.
- No servers, no cloud — the app is fully offline.
- Your play records are stored only on your device and are never uploaded.
