Let's say a game, you could see a score and normally we just find the score and hack it.

But, what if there is another hidden score, or numbers that also record the score, so when every time even you change the visible score, it will still compare with the hidden one, and replace it with the hidden score (unchanged).

In this situation, do we still able to hack it?

Yes. The number may be hidden, but it's still there.
Try using unknown initial value, increased, and decreased value scans instead of exact value.

Random= 500
Hidden= 600
Actual score= Hidden-Random
Shown score= 100

But alot of the time there will be much more advanced hacking prevention, which would cause you to have to only use "changed value".

Something else you could try is "See what writes to this address" after finding the shown score.

er...i dun get what you mean with the:

Random= 500
Hidden= 600
Actual score= Hidden-Random
Shown score= 100

well, even its the hidden score, it might not be that straight forward.
For exp: the visible score is 500, then the hidden 1 might be 637 which add 137. How would we know how much we should add?

edit: the "See what writes to this address" is like we get the visible score, then we can check which memory has connection with it?

That was an example of why "increased" and "decreased" scans should be used. That's how basic hacking is blocked, or temporarily prevented most of the time. Along the way a game usually gets better hacking prevention, but that mostly only applies to online games.

You could have something like:
self= val1 / val2 xor val3 ^ val1 * val2 - self
where the value is constantly changing, and no matter of scanning could point you to the correct address easily, which is why you should use "Find out what writes to this address" to see what's going on, and where the value is stored.

In some cases, you may have to set a debug register or flag.

hmm...i scaned the numbers out, but when i go for "See what writes to this address", it scanned out 2 codes, i click on replace and stop, then i wanted to continue, but the whole browser seems hand like tat =.=
