The aim in CodeWord is to uncover the secret five letter word that has been hidden behind the question marks at the top of the screen. You do this by guessing combinations of five letters. After each guess, you will be told how good that guess was: a light green circle indicates a letter that was correct but in the wrong position in the word, a dark green circle indicates a letter that was correct and in the correct position in the word. Enter letters by clicking on one of the solid green squares and choosing a letter from the panel on the left side of the screen (or from a previous guess). You have ten guesses before the game ends.
