• AFAIK, you should specify the source of the puzzles, otherwise it would probably be put on hold. – WhatsUp Oct 21 '19 at 19:37

1)

Diagonals - 1x3,2x2,3x1 and 1x1,2x3,3x2.
So now it is easy to add 3x3 when you consider 1x2 and 2x1.
In each color there is 1-2-3 black squares, 1-2-3 dark grey squares and 1-2-3 light grey squares. So for blue squares i need to find square with 3 black, 2 dark grey and 1 light grey.

2) - is green surely correct solution?

Because it looks like dots are moving always by 1, so B. Sometimes you cannot see them, because they are under black squares, but still there.

3)

Changing order is x → o → ▲ → x (…), except third to first row, which is just simple turn. Each symbol after change move by one to the right or new row.

4)

D, first and last row has always only one change and for columns next one has two things in common.

5)

A, Like normal clock, except 3 clock hands moving clockwise each turn and one counterclockwise.

• Thanks for your answer. However, I'm having trouble understanding your explanations... Could you please elaborate a little more? For example, in 1) what does 1*3, 2*2, 3*1 mean? – neverevernever Oct 22 '19 at 14:51
• Clarification for @Jan Ivan answer n°2: each dots move 1 by 1, when they cross a black square, their color changes. foir me, the answer is the last one (with 2 white dots) [Answer posted by a user without enough rep to comment here; converted to a comment.] – makao Oct 23 '19 at 15:14
• @neverevernever I think the 1x3,2x2, and 3x1 refers to positions in the 3 by 3 square. So, Jan Ivan is saying there is a diagonal made up of the blocks at the coordinates (1,3), (2,2), and (3,1). – jazhang Nov 23 '19 at 18:49

1.

There are three of each shape in each colour, so we must have black3, darkgrey2, lightgrey1. There are 3 vertical images and 5 horizontal, so the answer is F.

2.

The circles occupy 1&3, 2&4, 3&5, etc..., and are covered by black squares, so either F or H. The circles also change colour when under a black square and at no other time, so H.

3.

B, as Jan says.

4.

D, as Jan says.

5.

A, as Jan says. Here's an image to demonstrate:
