About Binairo

Binairo — sold under the names Takuzu and binary puzzle, and the family that LinkedIn’s Tango belongs to — is logic puzzling at its most distilled: two symbols, three rules, zero arithmetic. The entire game is deciding which of two digits a square wants to be, and being certain before you commit. Use the three rules together: an equal count alone does not make a completed line valid.

A new board is generated every day and checked for a single answer that can be reached by deduction alone. Once the daily board is done, New practice deals another one as often as you like.

Strategy tips

  • Twins seal their ends: wherever 1 1 sits, both flanking squares must be 0.
  • Split pairs work the same way: the middle of 1 _ 1 can only take a 0.
  • Watch the line budget. The moment a row holds its third 1, every remaining blank in that row is a 0.
  • When a line is down to its last two blanks, compare it with the finished lines running the same direction — one arrangement would copy a finished line, so the other is forced.

The common mistake is to stop after balancing a line: a row can have three 0s and three 1s and still duplicate another completed row. Compare the remaining candidates with completed rows and columns before committing. For a colour-region version of placement logic, try the Queens Puzzle; for a cross-number version of the same deduction habit, try Sum Cross.
