How to play Binairo

1. Fill with 0 or 1. Every cell must contain either a 0 or a 1 when the puzzle is solved.
2. No three in a row. You may never place three of the same digit consecutively in a row or column.
3. Balance each line. Each row and each column must contain exactly as many 0s as 1s.
4. Keep lines unique. No two rows may be identical, and no two columns may be identical.

Binairo strategy & tips

• A pair like 1 1 forces a 0 on each open side to avoid three in a row.
• When a row already has all its 0s placed, fill every remaining cell with 1.
• Use the uniqueness rule late: a row that would duplicate another is illegal.
