The computer mastermind has chosen a secret code. Can you crack the code before you run out of guesses? Guess the Code Free HD is the best codebreaker game for the iPad. Your iPad chooses a sequence of colors and you must try to guess the sequence within a specific number of guesses. Guess the Code Free HD includes a host of exciting features, including: * Great graphics and exciting sound effects * Configurable difficulty levels * "Use Letters" mode for colorblind players * Automatic save when you exit the app or receive a phone call If you are a fan of Mastermind, Bulls and Cows, or Vault Breaker, this is the game for you!

The result pegs tell you the number of guess pegs that are in the right position or are the right color, but not which ones. The code does not change over the course of the game and it is definitely possible to figure out the code in the number of guesses allotted.
