Each turn in The #UpsideDownChallenge Game, the active player draws a challenge card, which might be an individual challenge or a group challenge. Whoever the active player is dons glasses that flip their vision upside down, then they try to do what they've been challenged to do, such as giving someone a high five, pouring water into a glass, or drawing a picture.
You win and lose points along the way, and whoever first collects six points wins!
