Alright!
Now I’m on a bit of a different schedule from you guys so I’m not sure how this will go, but I’m thinking of a four digit number that’s meaningful to me …
3210?
It really doesn’t matter. We can submit our guesses, and you will process them when you want.
My guess is 7654.
7654 - 1 bull
How do you do the table thing?
You forgot about Prof.Pepperwinkle’s 3210.
You can inform us traditionally, if you don’t know how to build a table.
I will look for the source now.
This thread:
In the section about tables, you should use the part after this line:
3210 - 1 bull 2 cows. This may be a quick one!
| guess | Bulls | Cows |
|---|---|---|
| 3210 | 1 | 2 |
| 7654 | 1 | 0 |
Not necessarily.
My guess now is 3219.
8012?
Although there are are still something like 30 numbers that are logically consistent with the evidence we have, I suspect I know the answer. If I’m right then 3219 will yield 1 bull and 2 cows and 8012 will yield 0 bulls and 2 cows.
| guess | Bulls | Cows |
|---|---|---|
| 3210 | 1 | 2 |
| 7654 | 1 | 0 |
| 3219 | 1 | 1 |
| 8012 | 2 | 0 |
3712?
The number I was thinking of obviously wasn’t right. I think there are two possibilities remaining and I have no basis for picking between them, so I’ll wait until after the results from Prof.Pepperwinkle’s latest guess.
| guess | Bulls | Cows |
|---|---|---|
| 3210 | 1 | 2 |
| 7654 | 1 | 0 |
| 3219 | 1 | 1 |
| 8012 | 2 | 0 |
| 3712 | 2 | 0 |
That is indeed the one! It’s the postcode of the suburb of Parkville where I formerly lived and currently work 
OK, I’m thinking of a four-digit number. You may begin guessing.
I will submit the first guess: 9753.
An inspired guess. 9753 has two bulls and one cow.
