Zovo Cryptogram Maker

Make printable cryptogram puzzles with answers from your own quotes, for a class, a club newsletter, a puzzle night or a grandparent who loves cryptoquotes. Zovo Cryptogram Maker is a cryptogram maker that turns each quote and author into a letter substitution puzzle and gives you a PDF with an answer key.

Each puzzle gets its own letter key, shuffled at random from a seed rather than taken from keyboard order. No letter stands for itself, and each cipher letter stands for one plain letter only, so the puzzle has a clean answer. Each key is checked before the PDF is made, and the same seed reprints the same puzzles.

Choose easy (3 hint letters filled in), medium (1 hint) or hard (no hints), or set the number of hints yourself. A letter count grid under each puzzle helps solvers start with the common letters. Large print uses bigger letters and boxes for seniors and anyone with low vision. The author line can be part of the puzzle, as in a newspaper cryptoquote, or printed plainly. Up to 30 puzzles fit in one PDF on Letter or A4, and the answer key pages list each quote with its letter key.

Only the letters A to Z are enciphered. Accented letters such as é, ł and ü and letters from other alphabets are printed as written, and the result tells you when that happens.

Stuck on a cryptoquote? The solver answers in seconds. It ranks possible readings against an English word list of about 25,000 words, shows the letter key, the letters still open and up to 2 alternatives, and says whether its confidence is high, medium or low. Give it a known letter from the printed clue to narrow it down.

Limitations: letter ciphers only (no symbol or number ciphers), the solver reads English only, uses word frequency without grammar, and is often unsure or wrong about short texts, names, pangrams and sentences made of rare words (it then says its confidence is low), and the PDF prints Latin, Greek and Cyrillic letters (Chinese, Japanese, Korean, Arabic, Hebrew and emoji are left out).
