It's a mystery why there aren't more mobile adventures made, but one mystery that has made it onto iOS and Android devices is Relentless Software's The Trace.
The Trace casts players in the role of Detective Sam Pearce from the Baltimore PD, who's on the trail of a vicious murderer. While details about a story written by Sherlock: The Network's David Varela are sketchy, the player's assignment is clear in delving into the city's "murky underworld". In order to reconstruct crime scenes and solve the mystery, you must "search for clues, examine the evidence and solve the puzzles that will lead to a watertight conviction."
Designed specifically for mobile platforms by the creators of the Blue Toad Murder Files, the new game lets you explore its realistic and highly interactive 3D environments, allowing you to "navigate from room to room, zoom in to study [hundreds] of objects with ease, and scan for hidden evidence to help you solve this most puzzling of homicides."
