How to Play?

Crack the secret 4-digit system PIN within 10 attempts. After each guess, the terminal will give you clues:

🟢 Bulls: Correct digit in the correct position.
🟡 Cows: Correct digit in the wrong position.

Example: If the secret PIN is 8352 and you guess 8025:

  • 8 is correct and in the right spot = 1 Bull
  • 2 and 5 are correct but in the wrong spots = 2 Cows
  • Terminal Output: 🟢 1 Bulls | 🟡 2 Cows
