In Brainwaves: The Astute Goose, players must identify a burglar hiding in a crowd. What did the culprit look like? What colour were their clothes? And what animal accomplices did they have with them? Suspect cards are assigned a number, from one to six. Players look at these card, then turn them face down. On their turn, a player rolls two dice: one showing a number, the other a characteristic of the burglar card. If the player can correctly identify the item on the correct burglar card, they claim the card as a reward, then put a new burglar card in its place. Whoever correctly identifies the most burglars wins!
