🎮 How to Play

1. Start the game.
2. Choose a difficulty level (1, 2, or 3).
3. Choose the maximum number of attempts.
4. Watch out! Because colors can be reused, meaning the code could be green green blue red or green blue blue blue.
5. Enter your guesses as colors separated by spaces, for example:

red blue green yellow

5. After each guess you will receive feedback:

   • Black pin = correct color in the correct position
   • White pin = correct color in the wrong position

6. Guess the full code before your attempts run out to win the game.
