After each set of three numbers is entered the computer will give you clues to help you find the mystery number. A red light means that none of the digits are correct. The amber light means that one digit is correct but it is in the wrong place. A green light means that one digit is correct and also in the correct position.
Use deductive reasoning skills to find the mystery number in the least number of tries.
