The old, classic game of logic and deduction upon which Master Mind is most probably based!
Instructions: Guess the computer's four digit number in the fewest possible moves. After each guess, the computer will give you Bulls (or black marks) that each signify a correct digit in the correct position, and Cows (or white marks) that each signify a correct digit but in the wrong position. Then switch roles with the computer!
