Free Cryptogram Maker

Type a quote, a sentence, or a vocabulary list and get a coded puzzle students decode letter by letter. Print it with a starter letter and an answer key, or let students solve it online with hints. Free, unlimited, and ready in seconds.

What a cryptogram teaches

Decoding a cryptogram is pattern work: students look for one-letter words, common endings, and repeated letters, then test a guess against the rest of the message. That is spelling knowledge and logical reasoning at the same time, which is why cryptograms hold attention far longer than a word list ever does.

Set the difficulty for the class

Reveal several starter letters for younger students so they always have a foothold, or reveal none for a challenge. Shorter messages suit elementary classes; longer quotes work for middle school and adults.

Printable or online

The printable version fits one page with the code grid and a separate answer key, which makes it an easy sub plan or early-finisher task. The online version checks letters as students type and offers a hint when they stall.
