H&B　

It's a simple game where you can guess 3 digits.

If you enter a 3-digit number, the number of Hit or Blow will be displayed.
Using these as hints, I will guess the correct number.

Hit = numbers and digits are the same
Blow = Same number but different digits

Example: The correct number is 269

If you type 729, 2 will be counted as Blow and 9 will be counted as Hit.
