Product Description: Hasbro Games - Inspired by the viral challenges that have gathered billions of views across the Internet, this Don't Lose Your Cool game from Hasbro tests one's ability to remain calm under pressure. Players wear the Cool-O-Metre unit that measures heart rate, and the opposing team rolls the dice to determine how they'll try to get the player's heart rate to rise. When the metre reaches the red lights, the alarm sounds and the opponent wins that round.
