The new word won’t use any of the letter you’ve already ruled out (so if you guess “doors”, for example, the new word won’t have d, o, r, or s).
I know this isn’t exactly a new game, but I thought I’d share it because it is, as the name implies, absurd.
If you want another time sink, try redactle. It takes a random wikipedia page and redacts all but very common words. You guess words and it reveals them until you can guess the article title.
