About Cryptograms
A cryptogram is a famous quote scrambled with a letter-substitution cipher: every letter has been swapped for a different one. Your job is to crack the code. Type a guess under any cipher letter and it instantly fills in everywhere that letter appears, so each correct guess opens up the rest of the quote. Stuck? Spend a hint to reveal a letter for free. Decode the whole quote to win. No signup, no download, nothing uploaded.
