To begin, select "Play." 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.

You have two options to decode the puzzle:

Choose a letter you want to replace and click the letter on the onscreen keyboard that corresponds to the ciphered letter. Next, click the letter on the keyboard you wish to put in place of the ciphered letter, and the puzzle screen will be updated with your guess. All instances of that letter will be replaced with the same guess.

Or, click the ciphered letter you want to replace directly on the screen. Next, click the letter on the keyboard you wish to put in place of the ciphered letter, and the puzzle screen will be updated.

If you wish to erase your guess for a specific letter in the cipher, click the letter either on the keyboard or directly on the game screen that corresponds to the ciphered letter, then click "Clear." You can also erase all of your guesses by double-clicking "Clear."

When you're finished with the puzzle, you can share your score on Facebook.

Errors: If you complete a puzzle with incorrect letters filled in, you will be penalized 10 seconds for every incorrect letter.

Tips:

  1. Look for single-letter words, double letters within words, and apostrophes.
  2. Look for common words (e.g., the, an, that).
  3. The more you play, the more certain trends will become apparent.
