Supported inputs and limits

Bounded supplied text and supported letter/font scope. No text sourcing, content rights verification or secure encryption claim. Up to 2,000 characters. Only A to Z letters are substituted and cipher letters are uppercase; punctuation, spaces and digits remain. Original text and the full mapping appear in the on-screen result even when answer pages are off. Letters to reveal: 0–10. PDF text uses the supported built-in font character set; unsupported characters are refused rather than silently replaced.

The answer key contains the original supplied wording

Keep the answer pages separate from the puzzle when distributing worksheets. Only the supported letters are substituted; punctuation and other characters follow the stated text policy. A substitution puzzle is a learning activity, not a method for protecting private information.

Questions about Cryptogram Puzzle Worksheet

Will repeated letters keep one mapping?

Yes. The supported substitution is consistent within a generated puzzle.

Where does the puzzle text come from?

You supply it; the page does not fetch quotations.

Can I use this to protect a message?

No. Classical substitution puzzles do not provide modern secrecy.
