The Computer guesses a number in which all the digits are unique. When you guess a number, the computer gives an answer in the form of cows and bulls. A bull indicates a digit in the correct place while a cow indicates that a digit is there in the number, but in the wrong place. Using these clues, you have to find the number.
This game also has an interesting feature. The game can be played without touching the phone through voice. At any time tap the microphone icon and it will guide you.
Assume the computer generated number is 5196
* If your guess is 1234 the computer responds as 1 Cow and 0 Bulls - as the digit 1 is there in the number but at a wrong place.
* If your guess is 2956 the computer responds as 2 Cows and 1 Bull - as the digit 5 and 9 are there in the wrong place and digit 6 at the right place.
