I guess that these questions may use different logic independently or not i don't know. I just found one logic that fits only to the first one.

*These questions are from the one of high IQ Society founded by Xavier Jouve Ph.D for the top 0.3% of people along the IQ spectrum.

edit:other questions , last simillar type

  • $\begingroup$ does XJ explain the pattern of the boxes as a prelude to these type of puzzles anywhere? $\endgroup$ – JonMark Perry Nov 7 '18 at 7:31
  • $\begingroup$ No, these were totally new types. No additional information were given before. $\endgroup$ – user53678 Nov 7 '18 at 8:50
  • $\begingroup$ Ah, so they ARE separate puzzles rather than 3 pieces of one; thanks for the update. I don't know how much of a difference that makes but I feel like the logic between each can vary much more than if they were linked. Now, were 45-48 also the same type of puzzle? IE further examples of those above? $\endgroup$ – Dorrulf Nov 7 '18 at 22:20
  • $\begingroup$ link this is other questions, link this one only seems simillar type that left. sorry for my previously not mentioned about this. $\endgroup$ – user53678 Nov 7 '18 at 22:38
  • $\begingroup$ As you took this test, did you find that the previous questions, starting from 1, helped you develop a progressive understanding of the structure for the following problems? That is, by completing questions 1-10 in order, did you find you had a better understanding of the structure and what they were looking for in questions 11-20? In the end I guess I'm asking if you have a link to the test you took so that we may investigate to gain further insight into the specific questions you are asking about. $\endgroup$ – Dorrulf Nov 8 '18 at 1:08

I always found these kind of puzzles silly. There are an infinite number of justifications one could make -- and what you're really trying to do is predict the kind of justification a test-maker would deem sufficiently intelligent-sounding so as to warrant consideration.

That being said, here are my thoughts:

Puzzle 1

Answer 2. All blocks have to have at least one pair. A pair can either mean two white pieces adjacent to each other and in the same direction, or a single black piece anywhere in the same direction. We can rule out 1, 5, and 6 because they either don't have adjacent white pieces, or they have more than one black piece.

Puzzle 2

Answer 3. Pretty straightforward. You need a black block in every possible horizontal configuration to make a grouping of 'four.'

Puzzle 3

Answer 6. It's hard for me to fathom why any combination of pattern ideas would yield a completely distinct block from one already present. The most obvious answer would be half black (on top) and half white. Given that such a block is not present, perhaps the answer is as silly as "pick a block already present in the above diagram."
