Introduction
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 in as less times as possible. It is similar to Mastermind, but the four digits are different to each other. 4digits has both graphical user interface version and textual user interface version. This manual demonstrates the GUI version.

Playing 4digits
When you start a game, what it looks like is show in Figure 1. You are given eight times to guess a four-digit number. A digit is marked A if its value and position are both correct, and marked B if only its value is correct. You win the game when you get 4A0B. Good luck!
Figure 1 The main window when you start a game.
In Figure 2, the answer is 5184, which is known somehow. The first guess is 1234, then you get 1A1B. Why? 1A because '4' in 1234 and 5184 has the same value and position, and 1B because '1' in 1234 and 5184 share the same value but different position. If you enter 3456 then, you get 0A2B, because the values of '4' and '5' are right but there positions are not correct.
Figure 2 You get 1A1B when the answer is 5184.
A typical game in which the player wins is shown in Figure 3. The answer 7564 is guessed in 96.3 seconds.
