The number of searches on google for puzzles have been steadily declining since 2004. Are people just not interested in simple puzzles anymore? My first thought was maybe people are playing more online games.
But I think the decline in searches for the word “puzzles” is more tied to the decline of searches for sudoku. It blasted onto the scene in 2005, and naturally has calmed down once people figured out what it was.

yea, the suduko craze is over. My wife rode that wave. We always called it “suduko” instead of “sudoku”
