Only variations the TV show has is the 6 word version on Saturday and some comedians made a sketch with a 19 letter version: words like "Marshallplanachtige" [0]

EDIT: of course there's also this classic: https://www.youtube.com/watch?v=U7qxpAUKy4c in which some dude tries to not say a word he probably saw in a porno but does have to say it of course so mispronounces.
Not really true as it is, being based on local time. For example, there's only a one hour period each day where someone in New Zealand and someone in Hawaii have the same word.
Fortunatly Wordle clearly signals it with a countdown timer, instead of leaving it up to the reader to figure out what "day" they mean like other daily puzzle sites or people on the internet in general.
Anything that takes away from everyone getting the same word on the same day will absolutely nuke its popularity. There's really nothing novel about the game to make it popular other than that. Don't get me wrong, it's fun and well implemented, but the concept existed before Wordle. What makes Wordle successful is how dirt-simple it is to share your results on any medium.
