Nice start.

ok so just for clarification, you're going by the same rules; that if, say the answer code that we were trying to guess for was #58#
then in this case
* the 5 was there and was in the correct place (so it was an X)
* the 8 was there but not in the correct place (so it was a /)
so in this situation it usually would have been [ ] [X] [ ] [/]
but instead, because the # and the other # were not significant, you shift everything over to the left, right?
so it's [X] [/] [ ] [ ]

The indicators are ordered X's first,  then slashes.  The order of the indicators means nothing.

oh well that makes this like 500x harder
so what we know is that the code is either
7--- or
-5-- or
--6- or
---8
and that within one of those four codes is another number from 7568
leaving us with 4(4*3) = 48 different possibilities based on those two numbers alone
add in the fact that the other 2 digits that can range anywhere within the ten digit range and you're looking at (2*10)*4(4*3) = 960 different possibilities??
i think i'm forgetting something but either way it ain't pretty
let's get cracking
i think it's best if we try out one new number and use one of the four confirmations i said above
let's try --6-
and throw in a 3
make sure we keep two of the numbers from 7568 in case we get lucky, how about 5 and 8?
toss it around and let's give it a go

8365


edit note: for those that actually read and understood all that junk up there (probably none of you) i was also taking into account the idea that the X and / may have been created because the number was repeating a digit twice, such as having multiple 7s. hell the number could even be 7777, that is one in those 960 possibilities.

I'm so unique and edgy because I read the whole message.

I read the whole message, didn't understand a word.

6 is in the third spot?

Code 1263

8547 is my new guess.

What. That doesnt make any sense.

Yes it does, the code has none of those numbers in it.

Amateurs at Mastermind often forget how important it is to get the entire code wrong. Knowing you have 5 numbers to work with rather than 10 makes everything so much easier. We're allowed to use 0, correct?

Yes.
