Binairo - Binary Logic Puzzle

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. And when you get stuck, the hint tells you why a cell is decided, not just what goes there.
A calm, Japanese-inspired design makes a few minutes a day feel like a quiet reset.
