Questions
- How is the code chosen?
- The 26 letters are shuffled with your browser's secure random generator. Every letter maps to exactly one other letter and no letter ever stands for itself, so the code can always be reversed. Numbers and punctuation are left as they are.
- How do the hints work?
- Each hint picks one letter of the quote at random and fills in every place where it appears. Hints are printed in the answer boxes, so the solver starts with a few anchors.
- What happens to accents?
- Accents are removed first, so “é” becomes E. Letters outside A to Z, such as “ß”, are kept as plain characters and are not encoded.
