I made some progress thinking about the white circles (the logic behind the black squares remains unsolved): I have no idea what is going on with the black circles. Maybe someone has an idea?

Hello to all, here is a new IQ test question. Perhaps this is a good place to get the problem solved? The question involves a 3x3 matrix and there is usually a logic sequence going from left to right, and sometimes also up to down. The idea is to supply the missing corner chosen from the eight samples below.

Hello to all, I am new to this forum. Recently I did an online IQ test. There is one which I still can't solve after driving myself nuts looking at it. Perhaps this is a good place to get the problem solved? The question involves a 2x2 matrix and there is usually a logic sequence going from left to right, and sometimes also up to down. The idea is to supply the missing corner chosen from the eight samples below.
