Wordle unlimited is the Wordle game that has no limits or constraints. The most obvious advantage is that if you press Enter after finishing a task successfully, a new word will emerge in its place without having to wait a full day.
The length of the words is another differentiating aspect. You can modify the number of letters in the mystery word from four to eleven from the Settings menu. In particular, you should choose the five or six-word setting to get the most out of the game.
