Bulls and Cows

But I will continue as planned: 8642. :slight_smile:

8642 has no bulls and one cow.

# guess Bulls Cows
1 9753 2 1
2 8642 0 1

“And thus, 0 and 1 can be already eliminated.”

“Amazing, Holmes.”

“Elementary, my dear Watson, elementary.”

My next guess is 9653.

9653 yields two bulls and no cows.

# guess Bulls Cows
1 9753 2 1
2 8642 0 1
3 9653 2 0

A clean shot: 6 will join 0 and 1, and 7 can’t wait to be promoted to the rank of bull.

Let’s try the following: 7853.

7853 has one bull and one cow.

# guess Bulls Cows
1 9753 2 1
2 8642 0 1
3 9653 2 0
4 7853 1 1

My next guess is 9257.

Well, that didn’t take too long. Congratulations, PlaceboTarget, you have solved the puzzle.

Thank you. :slight_smile:

When the stars align, everybody can get as sharp as a tack.

I will hold the trophy until someone guesses the next secret number:

I have time for one guess before going to bed. How about 9876?

Thank you for your guess. :slight_smile:
