Inspired by the internet's viral challenges that have gathered billions of views, Don't Lose Your Cool tests one's ability to remain calm under pressure. Players wear the Cool-O-Meter that measures their heart rate, and the opposing team rolls the dice that determine how they'll try to get the player to get flustered. A change in heart rate effects the meter and when the meter gets high enough the lights get to red, the alarm sounds, and the opponent wins for making that player lose their composure.
