After each of these chances, the creator of the code (in this case, the computer) must reveal how many pegs are the correct color in the correct location, or the correct color in the incorrect location, or completely incorrect. With this little information, the code breaker must improve upon his previous guess to crack the code. For this game we'll allow you to have 12 guesses before requiring a forfeit."""
