I Spy Spooky Mansion is a game based on the book I Spy Spooky Night from the popular series of picture riddles. In this game, you go across several rooms in the house deciphering various riddles. Each riddle earns you a piece to a puzzle, which will reveal how to escape the haunted house you are currently in. There are 13 rooms with two riddles each, as well as a few minigames such as Creepy Collections.
The game is fully point-and-click, with the riddles read aloud at the bottom of the screen for you to look at any time. There is also a ghost-building minigame where you hunt around the house for ingredients, and is ultimately the machine used to escape from the house once you finish the puzzle.
