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!
