Cows & Bulls Multiplayer

.

**How to Play**:
**Setup**:
🔍 The game creates a secret four-digit number. This number can have any combination of digits from 0 to 9 and should remain hidden from the player(s) (the codebreaker).

**Guessing**:
🤔 The codebreaker starts by making a guess of a four-digit number. This is their attempt to guess the secret number. The digits can't repeat in the guess.

**Feedback**:
📢 The Game provides feedback on the guess using "cows" 🐄 and "bulls" 🐂:
- A "bull" represents a correctly guessed digit in the correct position.
- A "cow" represents a correctly guessed digit in the wrong position.

For example, if the secret number is "1234," and the guess is "3147," the feedback would be "1 bull" (for the "1" in the correct position) and "2 cows" (for the "3" and "4" in the wrong positions).
