DeWordle is a tool used to reverse-engineer Wordle game diagrams and the key to playing is understanding that not every color-block pattern is possible in every game.
As a result, the list of potential answers can be narrowed down to only those that could generate each pattern entered into the board because there is just enough variation in the guess patterns that can be made for each answer.
How to play
All of the answers can result in an empty board when you first play. You make a guess about the colors of a pattern of squares, let's say green, yellow, and gray. There are currently 1,994 answer words left after the game eliminates any answers that could never produce that guess pattern. It is your objective to keep making pattern guesses until there is only one answer word left.
