Wordle
The Wordle game is similar to many other applications in which the user has to guess a five-letter word. Wordle seems elementary, which attracts users: the player must enter any five-letter word into the crossword cells. If among them there is a letter that is part of the hidden word, and it is in the right place, the cell is highlighted in green. If the letter is guessed, but there is no place, the cell will turn yellow, and if there are no letters at all in the word of the day, the cells will remain gray. Wardle prototyped the game in 2013 and perfected it during the pandemic for his girlfriend who loves word games. Back in November 2021, Wordle, as its creator said, had only 90 users, and in early January their number reached 1.8 million people.
