Detective Solitaire The Ghost Agency continues the story of Inspector Magic. This time the detective is helping the Phantom Agency. The bloodhound is trying to prevent a disaster. He investigates crime scenes in the magical world. In this part, the number of locations has increased to 20. The hero will visit the witches' shop, a room with evidence, a gloomy alley, an abandoned home and other areas. To find clues, he has to solve puzzles, ranging from easy ones to more difficult ones. The number of levels has increased to 200 compared to its predecessors. In this continuation, new card backs and achievements have appeared (there are 15 achievements in total). But the interface remained the same.

Official Russian localizers translated the name of the project as Detective Solitaire: Phantom Agency. According to tradition for the series, the user can enter his nickname and select the difficulty before starting the passage. The player observes the field from above and removes the cards in a certain way, having guessed the correct sequence. For correct actions, coins are awarded – the local equivalent of points. A chain of successful decisions triggers a combo multiplier, which gives even more gold. The user can cancel his last move and use jokers. To gain access to a new location, you need to complete a sufficient number of stages in the current zone with a good result.
