Robert Lesser, a software engineer associated with U.S.-based data organization Observable, has created a series of visualizations tracking the difficulty of popular word game Wordle. He collected 15 million tweets showing players’ results, including the number of guesses they made. For each game, he labeled those won with one, two, or three guesses as shades of green, games won with four or five guesses, shades of yellow, games won with six guesses as orange, and lost games as red. According to the visualization, there was a noticeable increase in the average number of guesses taken to solve the game in the two weeks after the New York Times acquired Wordle.
