If you’ve been on Twitter recently, you will have seen the grid of green and yellow blocks with a number next to it. Wordle has taken over the internet with its simple web-only based puzzle (no app required). Its simplicity is why it is so popular; everyone has 24 hours to solve the same word. The addictive word game allows users to guess each five letters with no hints. After each guess, the color of the title either changes to yellow or green or gray, depending on how close you got to guessing the correct word.
