Who on Earth? is a party game wherein, in each round, players are each secretly assigned one 'partner' (person to describe) and, after all players answer 3 questions of the form 'If your partner was a (garden tool), what would they be?', all players attempt to guess which players were describing which players.Players score points for correct guessing of who was describing who, and then in a bonus round, the round's lowest scorer turns over a card from a second set of cards with questions of the form 'If you use the category of (species of animal) which player would best be described by (sloth)?'. All players answer secretly what they believe the card-flipper's answer would be, and for each match, both the matching player and the card-flipping low-scorer earns bonus points.Essentially a non-competitive party game, as all the players must play completely honestly for the game to work. - BoardGameGeek
