Brainwavesis a series of games developed by game designers and neuroscientists in which players challenge their episodic memory, that is, their memory of recent personal events.

InThe Astute Goose, players need to identify a burglar hiding in a crowd. What did the culprit look like? What color were their clothes? And what animal accomplices did they have? Number cards from 1-6 lie on the table, with a suspect card next to each number. Players look at these cards, then turn them face down. On a turn, a player rolls the two dice: one showing a number, the other a characteristic of a burglar card. If the player can identify the correct item on the correct burglar card, they claim that card as a reward, then put a new card in its place. Whoever collects the most cards wins.
