Bulls and Cows, a public domain code-breaking deduction game, was almost certainly the inspiration for Mastermind, designed by Mordecai Meirowitz and published by Parker Brothers in the early 1970s.Players will have to guess a random four-digit number to win the game. The number or bulls represents a correct number in the correct position while the number of cows represents a correct number in the wrong position.Enjoy!
