Of course Wordle is just Lingo but online. And Lingo is just televised Mastermind with letters instead of colours. Mastermind is an extension of Bulls and Cows and if you go back further I'm sure you can find another game like it.
There are some very big broadcasting companies that have put a lot of money into the "guess the word" genre and the New York Times probably know that they can't take down every game with similar rules.
The best they can do is find infringement of their trademark and pursue those who infringe upon it, or risk losing the trademark all together. They could also license the trademark, of course, but a blanket cease and desist letter is cheaper than negotiating a contract.
I'm asking about the name because you can't patent gameplay afaik, so even if it was a straight clone, as long as the word list (and code?) was original it would be OK.
On the other hand I recall Worlds.com suing (somewhat successfully?) both Second Life and Minecraft, so maybe you can patent game concepts?
I might be wrong as I'm not a lawyer, but I was under the impression that game rules are not protected by copyright.
WB games did patent a game rules system (Nemesis), but copyright is not the same as patents, and also I'm not sure how they got away with doing it.
The game concept (probably) isn't copyrightable, but the code certainly is.
But full credit to Wordle's creator, the one word a day and social media sharing stuff is the real secret sauce.
But it doesn't matter, you can't protect a game concept with intellectual property. Neither patents nor copyright allow this. The only thing that could be protected here is the name Wordle, the art assets (if there are any that are nongeneric enough), and the exact source code.
See Tetris, etc.
Secondly, everyone keeps mentioning (repeating?...) about this famous TV show in the UK; I have never heard of it until december. Reading the gameplay of the show on Wikipedia.... it sounds like an almost entirely different game, aside from the fact it (sometimes!) involves a 5 letter word, and you have to pick letters. Mastermind (the game), is so much closer
Did you actually see the tv show?

It'd be like claiming to own tic tac toe or rock paper scissors. It's just too simple imo.
