Cryptogram Maker
Paste any quote or sentence and get a classic cryptogram: every letter is swapped for another using a random substitution alphabet. Solvers work out the mapping letter by letter — on paper via the print view, or interactively on the page and in embeds, with automatic checking and hints.

Notes
- The cipher never maps a letter to itself, and digits and punctuation are left unchanged — exactly like newspaper cryptograms.
- Typing a letter fills every cell that shares the same cipher letter, so progress compounds as you crack the code.
- Runs 100% in your browser — your words and puzzles never leave your device unless you publish an embed.
