What you can do
Every puzzle is a real quotation written in a secret code — every letter of the alphabet swapped for another. Crack it one letter at a time and watch the words come through.
• 160 quotations across four difficulty levels, from short sayings to full passages • Every author is a classic voice — Shakespeare, Franklin, Dickinson, Marcus Aurelius, Twain — and every quotation is in the public domain • Tap a coded letter, type your guess, and it fills in everywhere at once • Conflicting guesses turn red so you always know where you stand • Three hints per puzzle when you're truly stuck • The author is revealed when you solve — no spoilers before
