What’s Up? is a classic version of the children’s game ‘Who Am I?’In this popular parlour game there are four categories of cards: people, 228, transport and animals. Each player puts a plastic card holder on their head, in which a card is placed. Each card has an image on it and the player must guess what is on their head by asking a series of questions, where the answer can only be yes or no. There are cards of varying difficulties for younger and older children.
