Frequently asked questions
What are the Binairo rules?
Each row and column has equal 0s and 1s, no three consecutive cells match, and no two complete rows or columns are identical.

Limits and accuracy
Use realistic values. The tool explains assumptions and does not replace professional, official or safety advice where that applies.
