In this game, all players will play face-to-face, telling their own stories. Each player will receive a story prompt, and get assigned to a role of either a truth-teller, who tells a true story of themselves but sounds ridiculous; or a lie-teller, who tells a fake story they just made up but sounds genuine. Then, they will all have the opportunity to question and interrogate each other. The goal for each player is to hide their identity as well as find out other players' identities. And here's the most exciting part: during this game, when the players are telling their stories or answering questions, other players get to see their heartrate! Imagine bluffing in the face, but your heartrate betrays you; or you secretly shake your leg while telling a truth to increase your heartrate, and make them believe you are telling a lie!
