Sudoku is a good example, but not the one you're still ignoring.
A. Of course "you really don't see sudoku being played that much (by adults even)." Solving puzzles requires concentration and is a poor public activity. You don't really don't see a lot of people working crosswords, either. And yet both appear in almost every newspaper you pick up. Do you really think that newspapers---which are undergoing a fairly substantial economic crunch---would waste the space on something that isn't popular? (And consider what that means for astrology...)
B. The invention of modern mathematics by the ancient Greeks---who were almost completely innumerate by today's standards---renders your "natural progression" untenable. And I'm not the least surprised that you chose to ignore it.
