Wordle is a daily five-letter word puzzle that rose from obscurity to viral fame in late 2021. Its premise is simple: players have six attempts to guess a hidden five-letter English word. After each guess, tiles change color to show how close the guess was—green for correct letter and position, yellow for correct letter wrong position, and gray for absent letters. Despite minimalist mechanics, Wordle catalyzed wide cultural engagement and prompted fresh conversations about play, design, and social interaction.
