Mystery Case Files: MillionHeir is a Nintendo DS video game developed by Big Fish Games and Griptonite Games. Nintendo published the title. In the game you are required to seek out selected items from a hand painted scene and select it using the stylus. After all the items are found within the set time, then you'll progress through the game. The goal of the game is to find the rightful heir of a hefty sum of money, and in all there are 12 potential people. There are 30 scenes to investigate and over 1,000 objects. This is the first game in the series to allow for multiplayer play, though in order to do so you'll need a game card for each player. In between investigations are touch screen mini games that "add to the depth".
