Mystery Case Files MillionHeir is probably one of the simplest games ever thought up, but yet the simple idea behind the title has been turned into a highly playable puzzle game.
In the game extremely rich millionaire Phil T Rich has disappeared from his mansion and you are placed in the role of the detective, who has been charged with getting to the bottom of his mysterious disappearance."
