Based on the social party game Spyfall. At the start of each round, players receive a secret card informing them of the group's location — one of twenty unique DC locations, including Arkham Asylum, the Daily Planet, the Hall of Justice, and S.T.A.R. Labs — except for one player who receives the Joker card instead. The Joker doesn't know where he is, but if he can figure out his location before his cover is blown, he wins the round! DC Spyfall includes a few twists on the Spyfall formula. Since Harley Quinn usually follows wherever the Joker goes, each round, one player may receive a location card with a Harley image; if they do, they try to feed the Joker player information about the location, even if they don't know that player’s identity! If the Joker player guesses the location, the two collaborators each score points — unless the superheroes can turn the tables on them and determine who Harley is.
