This game is an old code cracker game, like mastermind.

We start off with either a 4, 5 or 6 digit code.  Then each person has a guess, you guess say 1234 (the code is 1253), this would mean there are 2 bulls -2 digits that are correct and in the correct place- and 1 cow - 1 digit is correct but in the wrong position so you'd answer like this.....

 Carry on guessing until the code is cracked, then whoever cracks it does the next code and so on...

No back to back posting unless 24 hours without an answer.

Now get cracking!
