Who wants to be a Millionheir!

Mystery Case Files: MillionHeir is a simple but addictive observation game designed exclusively for the portable Nintendo DS. Mystery Case Files: MillionHeir combines a fun mystery storyline with seek-and-solve puzzles to create an adventure that can be enjoyed by everyone.

Following a classic murder mystery storyline - with a witty undertone that will appeal to all ages - the game sees the player become a detective who must use his eagle eyes to scrutinise detailed locations, spot clues and find items that will lead to the identity of the heir to a grand manor and a financial fortune. Each place the player visits may seem, at first glace, to be quite normal, but a sleuth's job is to look beyond immediate impressions... With closer inspection they will discover inventively hidden items in the background..

The player is presented with a list of items to look for using the Touch Screen. Often the item on the list requires lateral thinking. Does a "Spade" mean you should seek a small shovel, for example? Or does it mean the suit from playing cards, perhaps the Ace of Spades? If the player-detective's instincts are right he might be able to locate the item and by simply tapping it on the Touch Screen to collect it.

As the player investigates different locations and spots hidden items and clues, the storyline develops. Later in the game, the player will be able to use tools to open up different challenges, such as having to use a torch to see in a dark location or blowing into the DS's microphone to put out fires that may conceal hidden items.

For the real super sleuths there are timed "search and find" sections which increase in difficulty and test a players observation skills to the limit, and with the added ability to challenge up to four other friends or family, across the Nintendo Wi-Fi Connection, there's hours of fun to be had!
