Number Guesser

This is a game based on 'Bulls and Cows', and I don't have much content to say, just give you a funny one!! When a number and position are both correct, you'll get an 'A', and when a number is correct, but the position is wrong, you'll get a 'B'. According to how many 'A' and 'B' you got in before turns, you'll guess the answer. In the game, you can: --play Bulls and Cows with 3, 4, or 5 digit numbers; --a timer can record how long the time you use to success; --a pace counter can record how many paces you use; --make your success result to a local rankings save file; --play while listening a classic music; --with your friends, play the game one by one, and see who's the best and cleverest. Who's Jether? He is just a different guy in China.
