What is a Cryptogram?

A cryptogram is a substitution cipher puzzle where each letter has been replaced by a different letter. Your goal is to decode the hidden quote by figuring out which cipher letter maps to which original letter.

How to solve it

Start by looking for single-letter words (likely A or I), then short common words. Use letter frequency — E, T, A, and O appear most often in English. Once you crack a few letters, the rest fall into place.

Who is this for?

Cryptograms work especially well for middle school through adult solvers. They build pattern recognition, logical reasoning, and vocabulary. Seniors find them a satisfying daily brain exercise.
