There is a nice flow of logic in this puzzle. Well constructed.

Changed the nuance of the blue dots to differentiate it from the black dots.

So I messed up again. Unfortunately that seems to happen a lot. I actually linked the wrong puzzle before. Amazingly it still got 2 solves.
Now the link is proper and leads to the right puzzle that has been displayed from the start.

Clarified the rules.
Thank you Bankey for pointing out the uncertainties.

The rule does not clarify whether a circled digit n can have more then 1 "mirror" digit in a diagonal position. The example gives only non-duplicate pairs and has even number of circles, whereas the puzzle has odd number of circles (25). Please clarify.
*** A digit can mirror in two directions.
Thanks for clarifying, PetLov. I had meanwhile figured that out with some logic. :-) Thanks, again.
