Mystery Case Files: Madame Fate is the fourth instalment in the Mystery Case Files franchise and was released in November 2007. The player investigates Madame Fate’s Carnival and the carnival workers to see which one of them causes the fortune teller’s death at midnight. Mystery Case Files: Madame Fate introduces more types of puzzles (including word puzzles and multiple crystal ball puzzles) while also changing the way a player can find items. Sometimes the player must combine two items on the screen, other times they must locate hidden areas to progress. The bulk of the game is still finding hidden objects, but there are a lot of other types of puzzles. Mystery Case Files: Madame Fate also introduced hidden object scenes inside hidden object scenes into the gameplay. Source: Wikipedia, "Mystery case files", available under the CC-BY-SA License.
