Some people call this type of thing "enigmatic puzzles." Here's an example. There's a bunch of information that makes zero apparent sense. Maybe it's a bunch of crossword clues with no grid. Or a grid with no clues. Or a bunch of pictures of falcons.
It looks meaningless, or asinine, or impossible. But it means something, and if you somehow tune into the cleverness and creativity of the person who made it, you can unlock that meaning. I think that's beautiful. Although usually the secret meaning you unlock is something like "POWER BALLAD" or "MEGABYTE." Or a pun. But still.
These puzzles don't have fancy hints or answer checkers or explanations. They may have been written with very specific audiences in mind! They may be unfair.
