FAQs
Quick answers
What is a binary puzzle?
A binary puzzle (also called Takuzu or Binairo) is a logic grid where each row and column must contain the same number of 0s and 1s without repeating lines.
What are the rules?
Each row and column has an equal number of 0s and 1s, no three identical digits appear consecutively, and no two rows or columns are identical in the final solution.
How does difficulty work?
Difficulty controls how many givens are left in the puzzle. Easy keeps more numbers visible; hard removes more values so the logic steps increase.
Can I print multiple puzzles?
Yes. Each download produces a print-ready PDF with six puzzles per page, plus an optional solutions page.
Can I choose the grid size?
Yes. This generator supports 6×6, 8×8, 10×10, and 12×12 grids.
Do you store anything?
No. Everything runs locally in your browser, and no inputs are sent to a server.
Do you include solutions?
Yes. Enable the solution toggle to add a second page with the completed grid.
Can I print on A4 or US Letter?
Yes. The PDF is print-ready and you can select A4 or US Letter in your printer dialog.
