- Choose a source. Select "Random Quote" for a surprise puzzle from the built-in library of kid-friendly sayings, or select "Custom Message" and type your own phrase to encode.
- Pick a difficulty. Easy reveals 3 letters as hints. Medium reveals 1. Hard gives no hints at all.
- Click Generate Puzzle. A coded message appears with each letter replaced by a different letter. Below each coded letter is a blank space for your answer.
- Click any coded letter. All instances of that letter will highlight. Type the letter you think it really stands for. Every copy of that coded letter fills in automatically.
- Use the frequency chart. The chart below the puzzle shows how often each coded letter appears. In English, the most common letters are E, T, A, O, I, N. Use that knowledge to make your first guesses.
- Watch for conflicts. If you assign the same decoded letter to two different coded letters, those cells turn red. Fix the conflict to continue.

About Cryptograms
A cryptogram is a type of puzzle where each letter in a message has been replaced with a different letter using a substitution cipher. To solve it, you figure out the pattern one letter at a time. For example, if the coded message uses the letter Q very often, Q probably stands for E, since E is the most common letter in English.
Cryptograms build logical reasoning, pattern recognition, and vocabulary skills. They have been used for centuries, from ancient Roman military codes to newspaper puzzle pages. This version uses a library of 30+ kid-friendly quotes and sayings with no inappropriate content. Everything runs in your browser with no data sent anywhere.
