A Cryptogram is a puzzle in which each letter in a sentence is replaced by a different letter of the alphabet. The letters in the cryptogram are called “cipher” letters, and the letters you will write down are called “plain” letters.

Think of what the sentences might be saying and look for letter patterns that match the words that you think might be there.

BEGINNER: These cryptograms were created using a simple encryption system called the Caesar Cipher.

INTERMEDIATE: Think you've got the hang of it? Try breaking these three tough cryptograms.

ADVANCED: We saved the best for last!! See if you can solve them without looking at the solution first.
