Takuzu and Binairo usually mean the same puzzle: a square grid filled with 0s and 1s under three constraints. The names come from different publishers and regions, not from different rules.
Whatever name you use, the solve is the same: avoid three identical digits in a row, balance every row and column, and prevent duplicate rows and columns.
