Start a 2 player game on Normal. The same player must come in 2nd place at the end of the round twice in a row. You get points for answering truthfully, so one player needs to lie as much as possible. Have one player tell the truth every time and another player lie.
Refer below for tips:
How to tell the Truth:Telling the Truth in this game is very easy. Simply sustain a single note noise as if you were singing for the entirety of the countdown during your answer. A higher note is preferred. You will get 1,000 points and a Truth every time.
How to tell the Lie:Lying is much harder. The best way I was able to lie was to use a very monotone voice, speak quietly, and break up my words so the sound breaks apart. To be honest, it worked best when I tried to sound very uninterested and sarcastic. I was saying: "I just want this game to be over. Please." lol
