I hadn't heard of Wordle till yesterday, but as far as I can see it's just the old "Word Mastermind" game from the 70s, played in easy mode.
Readers will recall that in easy mode you get a black pin in the position of any correct letter in the right place and a white pin in the position of a correct letter in the wrong place. In standard mode the black and white pegs were sorted in order, so you didn't know which applied to each letter.
Any patent attempt in the UK should die instantly of prior art.
