Defuse a logic bomb

It is very easy to play.

Your task is to solve the number that will stop time and the bomb will not explode.

The number consists of four digits.

This number will be randomly generated from 0 to 9.

The numbers are not repeated in the number.

The timing of the bomb is different every time.

Don't let the bomb explode.

If you do not have enough time, you can add it by watching ads.

This is a time bomb, the time before the explosion is different each time, from 1 to 5 minutes.

You just need to guess 4 numbers and put them in their places, nothing complicated.

We start with 1234, then 5678 and determine how many numbers were guessed.

If all 4 digits from 1 to 8 have not fallen out, then perhaps these are the numbers 8, 9 or 0.

Remember, the number doesn't start at 0, that's another complication.

We look at the LEDs, they should all burn yellow or green.

Their number should be 4, burning LEDs.

If all are yellow, then you guessed all 4 digits in the number.

But we need to put all these figures in their place.

Yellow is such a digit in the number, green is this digit in the number and it stands in its place.
