How this page works
The puzzles above were built in your browser a moment ago, which is why there is no download and no PDF library to wade through. Press Print / save as PDF and your browser's own print dialogue takes over: choose your printer for paper, or "Save as PDF" for a file.
The page furniture — menu, footer, buttons and adverts — is removed automatically when printing. What lands on the paper is puzzles.
Paper sizes
The layout is measured in millimetres and fits both A4 and US Letter without changes. Choose one puzzle per page for a large grid you can write in comfortably, two for a good compromise, or four to six to save paper for a class set.
| Per page | Grid size on A4 | Good for |
|---|---|---|
| 1 | About 150 mm | Large print, pencil marks, poor light |
| 2 | About 120 mm | The usual choice |
| 4 | About 80 mm | A class set or a travel pack |
| 6 | About 76 mm | Answer sheets and compact packs |
Puzzle packs
Ask for 25 or 50 puzzles and you have a booklet. Generation runs in slices so the page stays responsive while it works, and the answer sheet at the end is numbered to match.

Common questions
Is there a PDF to download?
There is no file to download. Choose "Save as PDF" as the destination in your browser's print dialogue and you get exactly the same result, generated on the spot.
Will the answers print too?
Only if the answer-sheet box is ticked. The answers are placed on their own page at the end so a solver does not see them by accident.
Do the puzzles fit A4 and Letter?
Yes. The grid sizes are set in millimetres with margins that work on both, so nothing is cut off on either paper size.
Can I print the same puzzles twice?
Print the page again before regenerating and you get the same grids. Pressing Generate builds a fresh set.
