Using your smartphone, you will be given an app to download and a starting location. Once you arrive at the starting location, you'll send a text to check-in and get your game set up on the app. From your starting location, also known as your Home Base, the app will lead you from checkpoint to checkpoint around the city to collect clues and solve puzzles. Once you've completed all 3 quests, you'll come back to your Home Base and solve the final puzzle.
