 html version may require some time to download.

you are going to find out the 4-digit secret number, all digits are different

each time you guess the number, a hint will be shown like "1a2b", which means there's 1 bull (the secret has one of your digits, and it's in right position) and 2 cows (the secret has two of your digits, but it's not in right position)

example: the secret is 1234 and you are guessing 1345, the hint will be "1a2b"

you have 9 tries to figure out the secret, good luck!
