Déjà VuForgetting something you saw only seconds earlier is one thing; remembering something that has never happened is the opposite experience. Both of these feelings come together in Déjà Vu, with players reacting to cards as they pass to grab repeated objects.
In more detail, the 36 object tiles are spread out around the deck of cards. These objects are each pictured on cards in the deck exactly twice. The cards in the deck are revealed one by one, and if you think that an object on a card has appeared previously, then you can grab the corresponding object tile and place it in front of you. Are you sure of what you saw? You better hope so because if a newly revealed card matches an object tile lying in front of you — and an opponent spots that tile in time and identifies your false memory — then you're out of the rest of the round.
Once you finish going through the deck, players score points for the items they collected. A total of three rounds are played, and with each subsequent round players might find it harder to remember exactly what they've seen. Was the object shown before, or am I thinking of the previous round? Whoever collects the most points after three rounds wins!
