Binairo Generator
Takuzu-style binary logic grids — balance the 0s and 1s without tripling a digit or repeating a line. Every puzzle has exactly one solution.
About Binairo
Binairo (also known as Takuzu or Binario) is a binary logic puzzle played on even-sized grids. Fill every cell with 0 or 1 so that each row and column contains equal counts of both digits, no three identical digits appear consecutively in any direction, and no two rows or columns are identical. Every puzzle here is reduced from a full solution while a solver confirms uniqueness.
Tips
- Mark pairs first: any two identical digits with one gap force the middle cell.
- On the border between filled cells, 'two of a kind already placed' means the rest must be the other digit.
- Watch line uniqueness late-game — duplicate rows are the most common mistake.
FAQ
- What do the dots on the printed grid mean?
- Dots mark every second lattice intersection so counting cells in twos is easier on paper and e-ink screens.
- Which board size should I start with?
- 6×6 teaches all three rules in a couple of minutes; 8×8 is the classic daily-puzzle size; 10×10 and 12×12 add depth without new rules.
