No ads. No Wi-Fi needed. Your progress backs up automatically with your Google account.

WHAT YOU'LL SOLVE
• Atbash: basic mirror substitutions
• Visual ciphers: Pigpen, the Dancing Men from Sherlock Holmes, and the Knights Templar cipher
• Caesar: the cipher Julius Caesar wrote with
• Aristocrats: classic letter-substitution cryptograms with spaces preserved
• Aristocrat K1 & K2: keyword ciphers with a scrambled alphabet
• Patristocrats K1 & K2: letters regrouped into 5-letter blocks, no word boundaries
• Affine: number-based substitutions
• Xenocrypt: Spanish-language aristocrats (27-letter alphabet, with the Ñ)

EVERY PUZZLE IS A REAL QUOTE
Thousands of quotes from writers, scientists, philosophers, and statesmen, including Mark Twain, Maya Angelou, Aristotle, and many more. It's cryptogram practice that leaves you a little smarter than it found you.
