Wordle is a single-player puzzle game where the player is presented with five blank spaces for letters along with a grid of the English letters A-Z. The goal is to determine what the secret word is by proposing guesses in the form of five-letter words. Feedback is then given to the player about which letters in the proposed word match the target word. Letters not in the target word are marked as gray, letters present in the target word but in the wrong position are marked as yellow, and letters in the target word and in the correct position are marked as green. The player then uses this information to make another proposal. The game ends when the player either determines the target word or runs out of chances, which are capped at six proposed words. The final proposal must be the target word for the player to win.
A grid of the alphabet is displayed for the user to help them keep track of letters that are untested (gray), tested and found to be absent from the target word (black), tested present in the word but in the wrong position (yellow), and tested present in the target word and in the correct position (green).
Statistics are kept of the user's success rates among all past Wordle games played, and users may see data on all players' collective average number of guesses taken to determine the target word.
