A friend introduced me to Wordle, a puzzle game on the New York Times web page. It is a guessing game where you try to guess a five-letter word. Any correct letter will show up in yellow, or green if it is in the correct position. You have six chances to guess the word.
The on-screen keyboard helps you because it shows which letters have succeeded or failed so far. In my second and third guesses, I tried to use new letters so that I could narrow down the answer.
