Cows and Bulls game


Players must enter a string of four numbers into a text field in an attempt to guess a hidden number. If one of their digits is in the correct place it’s a ‘bull’, if it exists in the hidden number but is in the wrong place it’s a ‘cow’. The hidden number doesn’t contains any duplicate digits.
