I went to a party where the average age was 60yos.
I never even heard of Wordle until the old folks spent an hour talking about it and sharing strategies.
So I equate Wordle to "old people games" like Sudoku, crosswords, and all those freemium iPhone puzzle games. (Not that there's anything wrong with that)
Wordle became very popular among the Twitterrati. It blew up there because of the way you could share your result without spoiling the answer. The average Twitter user back then wasn’t that old.
