What is Binairo?
Binairo is a logic puzzle with only two symbols: 0 and 1. The grid starts partly filled, and you complete it by keeping every line balanced and never letting three of the same digit line up.
The rules take seconds to learn and the puzzles get deep fast. Play Binairo online free here, from quick 6×6 grids to large 14×14 boards.
How to play Binairo
- Fill every cell with a 0 or a 1.
- No more than two of the same digit may sit next to each other in a row or column.
- Each row and each column holds as many 0s as 1s.
- No two rows are identical, and no two columns are identical.
Binairo tips
Break up pairs
Two 1s side by side must have a 0 on each end. This single rule solves a surprising share of every puzzle.
Fill the gap between two
In the pattern 1 _ 1, the middle cell must be 0, otherwise three 1s would line up.
Count to finish lines
On a 10×10 grid each line needs five 0s and five 1s. Once a line has five of one digit, the rest are the other.
