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.
This reminds me of the fake gameshow on 30 Rock called Homonyms
“Sorry! It’s the other one!”
