Developed by the National Security Agency, NSA CryptoChallenge is a game that tests your pattern recognition skills through a series of cryptographs. Your mission is to decipher encrypted quotes, factoids, historical events and more. It’s you against the clock to see how fast you can crack the code.

NSA executes some of the nation’s most important and sensitive intelligence operations. To help us accomplish our mission, we’re looking for the best and the brightest problem solvers to join our team.

If you can solve these puzzles, you just might have what it takes to help NSA keep America safe.
