8105 has one bull and one cow. I believe that narrows it down to only one possibility, though it’s entirely possible that I’m mistaken. | # | guess | bulls | cows | | --- | --- | --- | --- | | 1 | 1234 | 0 | 1 | | 2 | 5678 | 0 | 2 | | 3 | 0912 | 0 | 2 | | 4 | 9056 | 0 | 2 | | 5 | 7195 | 2 | 0 | | 6 | 7520 | 0 | 2 | | 7 | 8105 | 1 | 1 | ---

We are still waiting for someone to guess the secret number. * * * In the meantime I have a different kind of secret number: πŸ”΄ 🟠 🟒 πŸ”΅ Here’s some information about it: πŸ”΄ + 🟠 = 🟒 + πŸ”΅ 4 🟒 - 7 πŸ”΄ = πŸ”΄ - 🟠 What is the number symbolized by the colored circles? * * * Or you can guess **bibliophage** ’s secret number. πŸ™‚ ---

πŸ˜… Yeah, I forgot to mention that the same rules apply. You can only use a digit once in this number. You were close though. ---

The solution is not unique. I have found three solutions so far. ---

I’ve come up with additional clues so that the solution should not be ambiguous anymore: So, this is a a different kind of secret number: πŸ”΄ 🟠 🟒 πŸ”΅ Each digit must occur in this number only once.

8169? Please look at the first hint. Does 8+1 = 6+9 ? No, it doesn’t. [Previous page](https://boards.straightdope.com/t/bulls-and-cows/917561.md?page=8)
