This is a quest in which you will have to follow clues and solve puzzles in order to discover new places and stories. To begin, you must go to the starting point and open the app. Once there, you will receive your first clue. Along the quest, you will discover some of the places used in filming the Harry Potter movies. Each clue will lead you from one place to another, giving you exact directions so you won't need a map, a GPS or a guide. When you solve the clues and guess the answer, the secret story of that place is unlocked. Start and stop whenever you want. The tour will take you from 1.5 to 2 hours to complete, but there’s no time limit so you can finish it at your own pace. After you buy the quest, you will receive an e-mail with instructions on how to play. Go to the starting point and be ready to begin the adventure.
