I was watching a Japanese game show.
The contestants were asked to find the black area.
I could tell that the black area was half of the overall area. However, the contestants said that
The alignment of this figure was based on some rules.
He does not said what rules was it nor mention that it was simply half black half white.
I might be overthinking this, but I was pretty curious whether there was such rule or not...
EDIT: Again, I can see that the area was half black half white. However, I just want to know if there is a well-known rule or pattern that fits this type of alignment.
