1. Configure your bundle
Choose level and amount. The puzzles come from the same generator as the online game: always exactly one solution, never guessing.
Print binary puzzles
Prefer pen and paper? Configure your bundle below and download it as a PDF: choose the level, the number of puzzles and whether to include the solutions. Large print puts one extra large grid per sheet.

How it works
2. Download and print
The PDF is laid out for A4 with a thick outer border and clear digits — perfectly readable on a black-and-white printer too.
3. Puzzle on paper
Simply write the zeros and ones in the squares. Unsure somewhere? The solutions (if ticked) are at the back of the bundle.
Prefer the screen, with hints and error checking? Play the binary puzzle online or first read the rules and solving techniques.
Frequently asked questions about printing
Are the printed puzzles the same as online?
They come from the same generator, but the print bundle uses its own weekly seed. A fresh bundle appears automatically every week — and within that week everyone gets the same puzzles, handy for puzzling together.
Are the solutions included?
Only if you tick the box. The solutions then appear on separate sheets at the back, with the given digits in bold so you can tell them apart from your own entries.
What does large print mean?
One extra large grid per sheet, with thicker lines and bigger digits — pleasant if you prefer writing large or see less well.
Does printing cost anything?
The PDFs are completely free, without an account or watermark. You only pay for your own paper and ink.
