Ghost Trick: Phantom Detective is an adventure game developed by Capcom for the Nintendo DS and iOS. Ghost Trick's story centers on the recently deceased protagonist Sissel, and his ghost's struggle to discover who he was when he was alive and who killed him. The player assumes the role of this ghost, who has the ability to perform various Ghost Tricks to solve puzzles and navigate the world around him.

Ghost Trick is an adventure game in which players control Sissel, a ghost that must use his powers to save lives. During gameplay segments, players can swap at will between the Land of the Living, where time flows naturally, and the Ghost World, in which time is stopped. In the Ghost World, Sissel can travel between objects within a certain radius. These objects are represented by blue cores, and in the Land of the Living, Sissel can animate these objects to perform actions, known as "Ghost Tricks", that open new paths or influence the characters around him. For example, moving a tray of donuts will prompt a character to change where he or she is currently seated, as well as giving Sissel access to new areas.
