But do the categories (Animal, Vegetable, Mineral) just make no sense against the possibile answers?
The instructions for the game are at the top. A player picks a word from a card and the other player has to guess the word they've picked, starting by asking if it's an animal, vegetable or mineral.
The items all have (A), (V), (M) so I am assuming that's how they fit in the categories?
And the way they "fit" in those categories seems to be on what they are made of/where they come from, for example a Piggy Bank has (M) because it is made of clay, an Egg has (A) because it is an animal product and so it goes
