The Defeat of Medusa (メドゥーサの敗北) is a deduction game from Japan. One player is the Medusa, who turns people to stone by her gaze. Another player is the Hero, sent to defeat the medusa. The remaining players are statues, previous victims of the Medusa, who know her weakness. The statues must convey this weakness to the Hero, before Medusa identifies it first. The Statues know what the Medusa's vulnerability is, and they choose to freeze in poses in order to suggest what it is. The hero must try and work out what this is and declare it before the Medusa does. If so, the Hero and Statues win. But if the Medusa has also worked it out, the Hero and Statues lose. Medusa's weakness could be a variety of things, and a deck of cards suggests the types of things it could be. For example, it might be 'a certain dish', 'a creature', 'a character', 'a certain occupation', 'a certain color'.
