        for (int i = 0; i < guess.length(); i++) {
            if (guess.charAt(i) == hidden.charAt(i))
                hint += "" + guess.charAt(i); // append the correct character at the right position
            else if (hidden.indexOf(guess.charAt(i)) > -1)
                hint += "+"; // append a '+' if the guessed character exists in the hidden word but at a different position
            else
