Can someone explain me how come Wordle can be acquire since it is an implementation of another game called Lingo? Isn't there some copyright or other intellectual property belonging to someone else?
Rules cannot be copyrighted. I can make a Wordle clone right now and as long as I don't reuse assets/names there's nothing they can do about it. See also 2048, which is a clone of 1024, which is a clone of Threes.
