Nerdle is a math game by replacing letters and words with numbers and equations. The game was designed by Reddit user, TheMann0707. The game was created with Wordle in mind, and its creators have called it "Wordle for math enthusiasts." The game gives you 8 columns of 6 guesses where you have to guess the equations daily. Just like in Wordle, you get color-coded hints for your predictions that you can use to come up with the right answer.
