There are few places in the world more mysterious and full of strange events than London. Prepare to enter the land of the inexplicable to discover its frightening stories on this haunted exploration game.

Each clue will lead you from one place to another, giving you exact directions, so you won’t need a map or GPS. When you solve it and guess the answer, the secret story of that place is unlocked. You won’t need a guide, just download the app, go to the starting point and you’re ready to go on a city exploration adventure.

After you buy the quest, receive a code that grants you access to the quest in the app (the app is free to download). The quest can be played at any hour. It will take you from 1 to 2 hours to complete, but there’s no time limit, so you can finish it at your own pace. The total length is about 2 miles (3 km).

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 smartphones. Alternatively, each person can purchase their own ticket.

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.
