About Takuzu (Binairo)
Takuzu — also known as Binairo or Binary Puzzle — fills a grid with only 0s and 1s under three rules: no more than two identical digits in a row, an equal count of 0s and 1s in every row and column, and no two identical rows or columns.
How to play
- Use only 0 and 1 in each cell.
- Never place three of the same digit in a row or column.
- Each row and column has equal numbers of 0s and 1s.
- No two rows are identical; no two columns are identical.
Tips & strategy
- Two equal digits force the opposite digit on both sides.
- Complete a line’s majority digit once half are placed.
