The object of the game is to try to break the code in as little moves as possible. The code is either a 4 digit number, a 4 character word or a sequence of 4 colors.

To play the game, enter your code starting from the top of the screen. Tap each of the 4 squares to enter a number, letter or color according to the game being played. Then tap the OK button. You will be given a green peg for every square in your entry that matches the same square in the hidden code, a red peg for squares that match a square in the hidden code but in a different place, and a X for squares in your entry that are not in the hidden code. You can copy previous codes into the current line by tapping on the result square for the line you wish to copy. To copy a single square from a previous result, just tap on the square you wish to copy.
