LOST has invited VIRTRIX to partner up in developing and designing an app for Mobile Devices and Tablet, both IOS & Android. The app includes AR elements and games played in the physical escape rooms to solve riddles and puzzles to learn history. In the old detention rooms, there sets an escape game "THE CLUE", sponsored by the Yau Tsim Mong District Office and the Yau Tsim Mong District Fight Crime Committee, which requires the participants' observation and collaboration skills to prevent and detect crimes by deciphering clues.
