Drop in 19 people and 1 AI into a chatroom, and then try to determine who is the AI. A lot of these adversarial questions may come off looking more like an aggressive AI than a human.
Each player can TALK, NOMINATE, and VOTE when a vote is called. AIs know who the other AIs are. Humans do not know who is AI and who is Human. Once per round, AIs eliminate a human through consensus in a secret conversation. Then, in an open forum, all participants can talk and nominate other players for elimination. After a nomination, there is discussion and then a vote. If the majority votes in favor of elimination, the player is eliminated.
The Humans win when all AI are eliminated. The AI wins when the Humans no longer have a majority.
I do like the idea, but all it would require is at least 2 people putting forward group strategies.
For example, one person says "everyone repeat your username", so everyone does. Of course, the one who said this could be the bot, so another person would then have to put forth a different challenge (something similar -- repeat your username backwards, or something).
What if I told the humans there was 1 AI, but there were really 15 AIs and just a few humans. How many humans would volunteer, "There may be only 1 AI, but many seemed just as inhuman."
