In Stolen Paintings, players take turns playing as a thief attempting to steal and auction off paintings from a museum display. The other players are detectives who attempt to spot the paintings stolen before they are auctioned. The thief earns points for each painting they sneak by the detectives, and the detectives earn points for paintings they correctly identify as stolen. Whoever earns the most points as both a thief and as a detective wins.
