This is a game where you guess a 4-digit number.
After selecting a number, press the GO button to judge whether it is correct or incorrect.

After judging, derive the correct answer from the number of "H" and "B".
*There are no duplicate numbers.


“H” – Number and digit match
“B” – Contains the correct number, but the digits do not match

※example
If the correct answer is "1290",
If the selected number is “2340”, it is “1H-1B”.

If the correct answer is "0583",
If the selected number is "1538", it is "1H-2B"
