Wordle UK is an online word-guessing game that challenges players to guess a five-letter word in six or fewer attempts. The game is simple: the player types in a five-letter word, and the game tells them how many letters are correct and in the right position, as well as how many letters are correct but in the wrong position. The player then has another chance to guess the word, and the process repeats until the player guesses the correct word or runs out of guesses.
