Re: Cow Bull 1
What's cow bull?
Its a game of guessing the number I have thought!
A four digit number starting with first digit 1 to 9, without repitition of digits.
Cow Bull 1.
I think of a four digit number. You have to guess what it is.
For example, I have thought of the number 9712 (remember, I always thinks of four digit numbers without repitition of digits and the first is always non-zero).
Your guess:- 3410 :- My reply would be 1 bull. Because 1 figures in your guess and my number, and in the same place (tenths place).
Your guess:- 3140 :- My reply would be 1 cow. Because the number 1 figures in both the number I thought and the one you guessed but its not in the same place!
Your guess:- 9087:- My reply would be 1 Bull and 1 Cow, because the number I thought of was 9712, 9 figures in both the numbers in the same place and 7 figures in both the numbers, but in different places.
Your guess:- 3456:- My reply would be Nil as there are no cows or bulls.
The idea is to guess the number with the previous results.
Revivial of the cow bull game
This time only three digit numbers, and in decimal!
Revived cow bull #1.

Ooh, I loved this game! Especially when we started playing in Hex and making hidden words with them.
Guess 4: 256
Why did the vector cross the road?
It wanted to be normal.

Re: Cow Bull 1
2/3rds of the credit goes to Mathsy and JRB for excellent follow-up guesses.

Re: Cow Bull 1
I wasn't particularly trying to be strategic, I just knew that my guess didn't contradict previous results and that ganesh loves powers of 2.
Very good Masterminding though. Now it's your turn!

Re: Cow Bull 1
What's not to love?
Let's stick with 3-non-repetitive-digit decimals. Guess away!
