How to play
A hidden code has four digits, each from 1 to 6, and digits may repeat. Enter four digits without spaces. After every guess, you learn how many digits are in the correct position and how many more are correct but in the wrong position.
For example, if the code were 1123 and you guessed 1214, one digit would be in the correct position and two would be correct but misplaced. Try using the feedback to rule out possibilities logically.
