A
Wordle has become one of the most popular online games in America since it came out last October. Players get six chances to guess and learn a five-letter word for the day. Many are sharing their game results on social media, adding more interest in the game. Here are other games that help learners with different subjects.
Mathematics
British data scientist Richard Mann of London was talking with his daughter about the popularity of Worlle. He thought there should be a game for people who like mathematics and developed Nerdle. It’s a daily game in which a player has six tries to guess a math solution.
Math teachers note that a Nerdle player uses logic, a careful way of thinking about something, to solve a math problem. It’s similar to how a Wordle player applies logic to guessing a word.
Geography
French video game developer Antoine Teuf invented Worldle in honor of that word game, Wordle.
Players guess a country based on its shape. They get six tries to guess a country based on information about the country. Teuf first shared the game on January 22. He said there would be two million visits a day to the game’s page a month later.
