I'm having flashbacks to Zynga buying Draw Something right as it was peaking for 200 million before a total collapse.
That being said, Wordle at a few million for access to that many daily users... Doesn't take a ton of them signing up for NYTimes puzzle accounts to make the math pencil out.
Happy for the creator, avid fan of the game myself. It's the perfect 10 minute break in the middle of the day.
