# Binary puzzle Binairo

A binary puzzle is a grid you fill with 0s and 1s under three simple rules, the same puzzle known as Binairo or Takuzu. Shade no three alike in a line, keep each line balanced, and make every line unique. Each one here has one answer, reachable by logic alone.

Difficulty

Larger grids have more lines to balance. Every puzzle solves by logic, with no guessing.

8×8, 17 given cells. Fill the rest with 0s and 1s so no three repeat and every line is balanced.
