Mastermind and alike have existed in many different forms over decades. None of them became as popular as Wordle, not even close. It's been mediocre and outdated for a long time. But, Wordle has features that makes it unique, welcoming, and viral. The alternatives you quote aren't even close. That doesn't mean none of them can catch up with Wordle. I was saying that most of them was getting it wrong (like removing daily word limits, making the game harder, more convoluted, asking for signup, adding ads, etc). Nope. That's not going to work.
