Embark on a quest around London as "Theodgar", a powerful Wizard who chose to live among humans and protect them. You will follow clues you'll receive in the app, and fight Ozin, the sorcerer who wants to destroy Earth.

Along the way, you will arrive at Westminster Station, Downing Street, Horse Guards Avenue, Trafalgar Square, and other popular locations from the Harry Potter movies. Take your time to explore them, while also reading their story in the app.

After you book the game, you’ll get an mail with instructions on how to play. Head to the Westminster Station metro station and use the access code to unlock the quest in the app. End the tour at the beautiful Clement Danes church.

For larger groups, one person can purchase access for the entire group by selecting the number of people in the group. All group members will be able to play the city game on their smartphone. Alternatively, each person can purchase their own voucher.

You can play as a group and solve the clues together as you walk, or you can split into smaller groups/teams and compete against the others. Each person can also play on their own, separate from the group, and meet the group at the end.
