Takuzu vs Binairo vs Binoxxo: Names and Rules
Takuzu, Binairo, Binero and Binoxxo commonly name the classic binary-puzzle family: balance two symbols in every row and column, forbid three identical symbols in a line, and keep rows distinct from other rows and columns distinct from other columns.
Read the publisher's rules rather than relying on the name or artwork. A related binary puzzle can omit a constraint or add relationship signs. Colours, 0/1, X/O and suns/moons can represent the same two values.
| Name | How to interpret it | What to check |
|---|---|---|
| Takuzu / Binairo | Common classic-family labels | Balance, no triples, distinct rows and columns |
| Binero / Binoxxo | Names used in puzzle collections and publishing | Küng's Binoxxo rules include all three constraints |
| Binary puzzle / Binox | Generic description or a publisher's collection name | Krazydad's Binox includes the distinct-lines rule |
| Binario / Binaire and spelling variants | May be a language term, alternate title or unrelated query | Do not infer a separate rule set from a search spelling |
| Tango-style puzzle | A related two-symbol format | = / × clues; distinct lines are not required on Solvedle |
What does “distinct lines” actually require?
No two completed rows may have the same sequence, and no two completed columns may have the same sequence. A row may match a column. This is different from a unique solution: distinct lines is a rule inside a board; uniqueness says only one full board satisfies all clues and rules.
Suppose a completed row is 010101 and another is 0101··. Balance leaves one 0 and one 1. The ending 01 would copy the completed row, so the second row must end 10. This is a local example; other columns still need to be checked.
Is Binoxxo the same as Tango?
Not under the rules used here. Both balance lines and forbid triples, but classic Binoxxo's distinct-lines requirement supplies deductions that cannot be applied to Tango. Tango's signs supply different deductions. See the full rule comparison.
Which version can I play or print here?
Solvedle Takuzu follows the classic three constraints and offers 6×6 easy and medium boards. Its progress is separate from Tango practice. Use the distinct-lines checkpoints or classic printable pack to learn the difference.
