Using the power of the smartphone, 3Quest Challenge transforms cities into massive playing fields for timed scavenger hunts. True to the company's name, the game consists of three "quests," each with a trio of checkpoints. Teams answer riddles or complete tasks to collect a clue that will be used to solve a larger overall puzzle. Teams then must return to the home base for another clue before setting off on the next quest, all while racing against the clock.
