James86134, I see. My game is inspired from an old movie.
"The Battle of Wits". There are two glasses of wine. Each round a random player gets to select which glass of wine is poisoned and which is not. The chosen player can be interrogated/questioned but cannot reveal which wine is poisoned (The player can ignore questions, too). So, the other players have to ask questions that hint at where the wine may be.
"All I have to do is devine from what I know of you. Are you the sort of man who would put the poison into his own goblet, or his enemy's?" ~Vizzini
There are three rounds at minimum. You win by surviving the third round, or being the last man standing (Everyone picked the poison goblet but you).
