# Large Binairo

A 12 by 12 Binairo is a long, satisfying solve for someone who has the smaller grids down: more rows and columns to keep balanced, and longer chains to follow. Like every puzzle here it is proved solvable without guessing, and the answer prints on page two.

PuzzleDesign

Difficulty

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

12×12, 39 given cells. Fill the rest with 0s and 1s so no three repeat and every line is balanced.
