The player plays as (best friends) Miley Stewart and Lilly Truscott as they search for the person who might reveal Miley's secret alter ego, Hannah Montana. The player must find clues and combine items to solve three original mysteries, with the help of gadgets: a specialized magnifying glass and a specialized flashlight. There is also an interactive dialogue and gesture system used to communicate with other people. In addition, Lilly may also ride her skateboard, rollerblades, or scooter in timed challenges. Players can also design customized clothing and access Hannah Montana's secret wardrobe via the Nintendo DS' wireless network. You have to search for clues with Oliver Oken's gadgets. You also have to avoid Amber, Ashley, and Jackson. In the end, when you finish the game you can go to the places and look for more wardrobe items and explore Malibu.
