3Quest Challenge, Lexington

With the power of the smartphone, 3Quest Challenge transforms cities into massive playing fields for timed scavenger hunts. True to its name, the game consists of "quests" to locate a trio of checkpoints, where teams answer riddles or complete tasks to collect a clue that will be used to solve a larger overall puzzle. After visiting each checkpoint, teams must return to the home base for another clue before setting off on the next quest, all while racing against the clock.
