Guess the Code is like MasterMind that you used to play – except the code is determined randomly. Use logic to determine the code of colors in the correct sequence, in as few tries as possible. Each time you guess, you get feedback as to how many correct colors and correct positions you have (but not which ones they are) and you can work out the solution by logic. Note – you can choose to break a code of letters instead of color (good if you are colorblind).
