What's this?

4digits is a guess-the-number puzzle game. It's called Bulls and Cows, and in China people simply call it Guess-the-Number. The game's objective is to guess a four-digit number in 8 times using as less time as possible.

I used to play this game on Wenquxing (An old PDA). Someday which I forget, I find this game is not available on computer. I did not searched an ideal one, and have to write it by myself.
