>>11951565In an individual square the number contention is:
12
34
56
Rules are the following:
1) The black dots all line up a series of parallel right diagonal line on the whole image. That means the black dot position of A, B, C, D, and F are valid.
2) Every image has two white dots that are directly adjacent to each other (diagonally do not count), but may be covered be a black dot. Images B, E, and F therefore not valid.
3) The white dots in the entire row must fill each of the six dot holes. For example, in the top most row there are white dots in 35; 46; and 12. There is a black dot that covers white dot at position 3 in the first square. For the final row that the white dots cannot appear in 126. There is a white dot in either 4 or 5. That means that B (again), C, D, and E are obviously not valid.
4) The white dots move 2 counterclockwise movements going left to right.
This means that image A is only one valid.
