1. Each player secretly picks a number (e.g. 4 digits).
2. Players take turns guessing the opponent's number.
3. After each guess, the defender's screen shows how many digits are correct — correct number and correct position.
4. The defender reads the count out loud.
5. The guesser enters that count on their screen to log it.
6. Use your guess history to narrow down the answer.

Winning: Get all digits correct to win. If you win but your opponent has had fewer guesses, they get one final chance to tie. If they also guess correctly — it's a tie! 🤝
