Welcome to our free cryptogram game! What's a cryptogram, you say? It's a special type of puzzle where a famous quote is encrypted with a scrambled alphabet cipher, where each letter has been replaced with a different letter. Your job is to figure out which letters have been substituted for each other and crack the code. If you're a casual player, try our casual play mode which gives you access to plenty of hints and help. Experienced cipher-crackers should try out the expert mode.
The cryptograms are organized by topic (see the list of topics on this page). We also have a couple of "editor's choice" collections, where we organized a series of quotes into a set of puzzles you can work your way through. Either way, bookmark this page and check back regularly since we add quotes on a regular basis and are editing several new collections.
When you figure out the cryptogram, we score your results and compare them with other players. Your points score is based on your solution time and how many hints are used. For casual players, don't be afraid to use your hints - we give you five free hints to start and you can use extra hints if you're stuck. Expert games offer the option of using NO Hints (hardcore play!) for a higher score. After you solve the puzzle, we compare your raw points with everyone else who solved the puzzle to get a ranking.
Simple letter substitution ciphers have been around for thousands of years. These were considered state of the art during the late Roman Empire, both the simple Caesar cipher (substitution cipher based on a consistent "shift" in the letters) to more advanced matrixs and letter swap routines. They have been used by military strategists, politicians, revolutionaries, and secret lovers. Today, they survive as a popular puzzle and brain teaser. The easy ones can be used as cryptograms for kids.
We've got a ton of free cryptogram puzzles and cryptography puzzles, both digital and printable. Want to sit and look at a puzzle on paper? No problem, check out our printable cryptograms.
