How this generator works

Make your first cryptogram

  1. Write your sentence

    • Type the sentence players will decode.
    • Every letter gets a symbol at once, and the same letter always gets the same one.

  2. Give a way in

    • Under the sentence you choose which letters are given for free.
    • Pick the vowels, the most common letters or letters of your own.

  3. Choose the symbols

    • Numbers by default, or your own picture per letter.
    • New cipher shuffles the code again.

  4. Play, then share

    • Play shows what players see.
    • Share has the link, the QR code and the print option.

Print as a worksheet

Print the blank code for the class and the answer key for yourself.
