If a Wordle user guesses a letter that's in the right place, that tile will then turn green. If the letter does appear at some point in the word, but not in the place the user has guessed, it will turn yellow. If the letter does not appear in the word at all then the tile will turn gray.

The game's popularity skyrocketed within months, growing from 91 players in November 2021 to more than 2 million by January 2022. This rapid growth caught the attention of The New York Times, which acquired it for an undisclosed seven-figure sum.
