Wordle sparked off sort of a global game jam around variants, maybe because it was such a wholesome project. And these variants have found players; there's a lot of people who play a whole bunch of daily word games, there's some youtubers, etc.

I've programmed 3; the way that went down is I was curious if an idea I had would be fun (two Wordles on the same board, sort of a mix between Wordle and a word jumble since you don't know which word the clues go to.) Since there was an open source implementation this only took me one night, and it was in fact fun and started gaining some traction as https://xordle.xyz

Then some game designer friends suggested their own takes and I implemented those too: https://fibble.xyz lies to you once per row, and https://warmle.org tells you if you're close to the right letter rather than if a letter is in the wrong spot which gives the gameplay a very different feel
